Given a right triangle with legs 5cm and 12cm, find the length of the hypotenus. Show work please

Answers

Answer 1

Answer:

13 cm

Step-by-step explanation:

We can use the Pythagorean Theorem to find the length of the hypotenuse. The Pythagorean Theorem is used to find a missing side to a right triangle.

The theorem states that [tex]a^2 + b^2 = c^2[/tex], where a and b are the legs, and c is the hypotenuse.

The legs of this triangle are already states - 5 and 12, so we can plug it's values into the formula.

[tex]5^2 + 12^2 = c^2\\\\25 + 144 = c^2\\\\169 = c^2\\\\c = \sqrt{169}\\\\c=13[/tex]

So the hypotenuse of this triangle is 13 cm.

Hope this helped!

keeping the restrictions in mind, solve the equation.
3/x+4 + 2/x-4 = 16/(x+4)(x-4)
A. what is/ Are The value our values of the variable that make(s) the denominators zero?
x=

Answers

Answer:

A. -4 and 4

B. No solution.

Step-by-step explanation:

The given equation is

[tex]\dfrac{3}{x+4}+\dfrac{2}{x-4}=\dfrac{16}{(x+4)(x-4)}[/tex]

A.

Equate the denominators equal to 0 to find the restrictions on the variable.

[tex]x+4=0\Rightarrow x=-4[/tex]

[tex]x-4=0\Rightarrow x=4[/tex]

Therefore, [tex]x\neq -4,4[/tex].

B.

We have,

[tex]\dfrac{3}{x+4}+\dfrac{2}{x-4}=\dfrac{16}{(x+4)(x-4)}[/tex]

[tex]\dfrac{3(x-4)+2(x+4)}{(x+4)(x-4)}=\dfrac{16}{(x+4)(x-4)}[/tex]

Multiply both sides by (x-4)(x+4).

[tex]3x-12+2x+8=16[/tex]

[tex]5x-4=16[/tex]

Add 4 on both sides.

[tex]5x=16+4[/tex]

[tex]5x=20[/tex]

Divide both sides by 5.

[tex]x=4[/tex]

Here the solution is x=4 but it is the restricted value.

Therefore, the given equation has no solution.

For the given rational equation, we have that:

A. The values of the variable that make(s) the denominators zero are x = -4 and x = 4.B. The equation has no solution.

Rational Equation:

The rational equation given in this problem is:

[tex]\frac{3}{x + 4} + \frac{2}{x - 4} = \frac{16}{(x + 4)(x - 4)}[/tex]

Then, applying the least common factor:

[tex]\frac{3(x - 4) + 2(x + 4)}{(x + 4)(x - 4)} = \frac{16}{(x + 4)(x - 4)}[/tex]

[tex]\frac{5x - 4}{(x + 4)(x - 4)} - \frac{16}{(x + 4)(x - 4)} = 0[/tex]

[tex]\frac{5x - 20}{(x + 4)(x - 4)} = 0[/tex]

Item a:

The denominator cannot be zero, hence:

[tex](x + 4)(x - 4) \neq 0[/tex]

[tex]x \neq -4[/tex]

[tex]x \neq 4[/tex]

The values of the variable that make(s) the denominators zero are x = -4 and x = 4.

Item b:

[tex]5x - 20 = 0[/tex]

[tex]5x = 20[/tex]

[tex]x = \frac{20}{5}[/tex]

[tex]x = 4[/tex]

However, x = 4 makes the denominator zero, hence the equation has no solution.

(6) (i) Express this requirement as a ratio (ii) Express the amount of tin required as a percentage of the total (iii) If the total amount of tin in a particular casting is 150 kg, find the amount of copper

Answers

Answer:

you need 17 parts copper and 3 parts tin in order to make brass

1. ratio of copper with respect to brass: 17:20

  ratio of tin with respect to brass: 3:20

  ratio of tin with respect to copper:   3:17

2. percentage of tin required in brass:  fraction of tin in brass X 100

  3/20 X 100 = 15%

3. if we used 150 kg tin in the alloy, then 150 kg is 15 % of the alloy

  (from last answer)

  150/x X 100 = 15%

  x = 1000 kg

if the total brass formed is 1000 kg, and 150 kg of it is tin,

copper used = 1000 - 150 = 850 kg copper

What is the common ratio of the geometric sequence below?

Answers

Answer:

The answer is option B

Step-by-step explanation:

Since it's a geometric sequence, to find the common ratio divide the previous term by the next term.

That's

[tex] \frac{48}{ - 96} = - \frac{1}{2} [/tex]

And also

[tex] \frac{ - 24}{48} = - \frac{1}{2} [/tex]

[tex] \frac{12}{ - 24} = - \frac{ 1}{2} [/tex]

Also

[tex] \frac{ - 6}{12} = - \frac{1}{2} [/tex]

Since the common ratio is the same for any of the terms chosen the common ratio of the sequence is

[tex] - \frac{1}{2} [/tex]

Hope this helps you

Answer:

B. -1/2

Step-by-step explanation:

The common ratio is the ratio between two numbers next to each other To find the common ratio, divide a term by the preceding term.

For example, if the term is 48, divide by -96.

48/-96 = -1/2

Another example, if the term is -24, divide by 48.

-24/48= -1/2

Let’s try one more example. If the term is 12, divide by -24

12/-24= -1/2

Therefore, the common ratio is 1/2 and the correct answer is B.

Problem PageQuestion A circle has a radius of . Find the radian measure of the central angle that intercepts an arc of length . Do not round any intermediate computations, and round your answer to the nearest tenth

Answers

Answer:

0.1π rad

Step-by-step explanation:

The question is incomplete. Here is the complete question.

A circle has a radius of 19m . Find the radian measure of the central angle θ that intercepts an arc of length 5m.  Do not round any intermediate computations, and round your answer to the nearest tenth.

The formula for calculating the length of an arc [tex]L = \frac{\theta}{360} * 2 \pi r[/tex]

θ is the central angle

r is the radius of the circle = 19m

L is the length of an arc = 5m

Substitute the given values into the formula and get the central angle θ

5 = θ/360 * 2(22/7)*19

5 = θ/2π * 119.4285714

θ/2π = 5/119.4285714

θ/2π = 0.041866

θ = 2π*0.041866

θ = 0.083732π

θ = 0.1π rad (to the nearest tenth)

Hence the radian measure of the central angle that intercepts an arc of length to the nearest tenth is 0.1π rad

Suppose that you roll two dice and don’t get to look at the outcome. Your friend looksat the outcome and tells you honestly that at least one of the dice came up 6. What isthe probability that the sum of your two dice is 8?

Answers

Answer:

2/11

Step-by-step explanation:

We have to calculate this by

p(B nA)/p(A)

= We have A¹ to be that none of the die roll gives us 6

P(A¹) = 5/6²

P(A) = 1 -5/6²

= 11/36

BnA = one die being 6 and summation being equal to 8

= BnA = (6,2)(2,6)

= P(BnA) = 2/36

Therefore we have (2/36)/(11/36)

The proper choice of toothbrush is important in dental care. On 14 patients, measures of Gingivitis were taken at the beginning of the experiment. After this, each was given an experimental toothbrush to be used for the next 45 days. Afterwards, dental exam measures were given again of these same individuals. The mean of the differences in scores was 5.5 with a sample standard deviation of 11.6. The mean score before the experiment was 56.4 with a sample standard deviation of 6.4 The mean score after the experiment was 60.6 with a sample standard deviation of 4.3 Let alpha = 0.05
What is the p value from the test of the previous hypothesis?

Answers

Answer:

The p-value of the test is 0.049.

Step-by-step explanation:

The dependent t-test (also known as the paired t-test or paired samples t-test) compares the two means associated groups to conclude if there is a statistically significant difference amid these two means.

In this case a paired t-test is used to determine whether the experimental toothbrush was effective or not.

The hypothesis for the test can be defined as follows:

H₀: The experimental toothbrush was not effective, i.e. d = 0.

Hₐ: The experimental toothbrush was effective, i.e. d < 0.

The information provided is:

 [tex]\bar d=5.5\\S_{d}=11.6\\n=14[/tex]

Compute the test statistic value as follows:

 [tex]t=\frac{\bar d}{S_{d}/\sqrt{n}}[/tex]

   [tex]=\frac{5.5}{11.6/\sqrt{14}}\\\\=1.7740617\\\\\approx 1.774[/tex]

The test statistic value is 1.774.

Decision rule:

If the p-value of the test is less than the significance level then the null hypothesis will be rejected and vice-versa.

Compute the p-value of the test as follows:

 [tex]p-value=P(t_{n-1}<1.774)[/tex]

                [tex]=P(t_{13}<1.774)\\=0.049[/tex]

*Use a t-table.

The p-value of the test is 0.049.

p-value= 0.049 > α = 0.05

The null hypothesis will be rejected.

Thus, it can be concluded that experimental toothbrush was effective.

vertically opposite angle. coointerior angles sum is 180°.

Now,

angle 6= 38° { Vertically opposite angle}.

angle 6 + angle 5 = 180° { as sum of coointerior angles are equal to 180°}

38°+angle 5 = 180°

or, angke 5 = 180°-38°

Therefore, angle 5 = 142°

Answers

Answer:

B=1 M=6 D=3

Step-by-step explanation:

the equations are 4M+4D+2B=38

                               M+D+B=10

                              2D=M

step two: 4M+4D+2B=38 (multiply 2nd equation by -4)

               -4M-4D-4B=-40

4M AND 4D cancels out and your left with -2B=-2 B=1

then you take the first equation and subsitute the third equation for M

step three:  M+D+1 =10 (SUBSITUTE B WITH 1)

M+D=9

STEP FOUR: take the last equation (M+D=9) and subsitute 2D=M

2D+D=9

3D=9

D=3

subsitute D=3 into 2D=M  so you get 2(3)=M M=6

DOUBLE CHECK USE THE SECOND EQUATION

M+D+B=1-

The required number of mice, deers, and birds are 3, 6, and 1 respectively.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements.

Here,
Let the number of mice be x and the number of birds is y
Number of Deers  = 2x
There are a total of 10 animals,
mice + deer + bird = 10
x + 2x + y =  10
3x + y = 10
y = 10 - 3x  - - - - - - -(1)


Legs of mouse = 4
Legs of deers = 4
Legs of birds = 2

Total number of legs = 38
4x + 4 * 2x + 2y = 38
4x + 8x + 2y =38
12x + 2y = 38 - - - - - - - (2)
Solving equations 1 and  2
12x + 2(10 -3x ) = 38
12x + 20 - 6x = 38
6x = 18
x = 3
Put x in equation 1
y = 10 - 3 * 3
y = 1

Now,
Mice= x = 3
Deers = 2x = 2 *3 = 6
Bird = y = 1


Thus, the required number of mice, deers, and birds are 3, 6, and 1 respectively.

Write an equation to describe the relationship between time (t) and the number of workers (n), which are inversely proportional.

Answers

Answer:

t = 8 / n

Step-by-step explanation:

Time (t) and the number of workers (n), which are inversely proportional.

t = k (1/n)

t = k / n

Where,

t= time it will take workers to finish their job

n = number of workers doing the job

k = constant of proportionality

He estimates that it would take 2 days for 4 workers to wash the windows.

t= 2 days

n= 4 workers

t = k / n

2 = k / 4

Cross product

2*4 = k

8 = k

The relationship between time an number of workers is

t = k / n

b.) $0.10
c.) $0.01
d.) $0.20

Answers

Answer:

The correct answer is:

Variance is a measure of the squared differences from the mean.

Variance is simply the square of the standard deviation. It is mathematically shown as:

[tex]s^2 = \frac{\sum(x - \bar x)}{n} }[/tex]

The critical value for this hypothesis test would be ________.

Answers

Answer:

0.1492

Step-by-step explanation:

Mean (m) = 9.5

Standard deviation (sd) = 3.4

Number of observations (n) = 50

Computing the test statistic :

X = 10

Z = (x - m) / standard error

Standard Error = sd/sqrt(n)

Z = (x - m) / (sd/sqrt(n))

Z = (10 - 9.5) / (3.4/sqrt(50))

Z = 0.5 / 0.4808326

Z = 1.0398 = 1.04

Using a P-value calculator, we can obtain the critical value with α = 0.10, hence, the critical value = 0.14917

23. Due to an increase in taxes on electronic devices, the price of a 46" LED flat TV screen has increased
to £845, which is 30% increase of the original price.
What was the original price of the TV prior to the increase?​

Answers

Answer:

£591.5

Step-by-step explanation:

First find the price increase by multiplying the new price by 30 percent . Then subtract the answer from the new price.

The original price of the TV prior to the increase is £650 and this can be determined by using the unitary method.

Given :

The price of a 46" LED flat TV screen has increased  to £845, which is 30% increase of the original price.

The following steps can be used in order to determine the original price of the TV prior to the increase:

Step 1 - The unitary method can be used in order to determine the original price of the TV prior to the increase.

Step 2 - According to the given data, the increased price of the TV is £845 which is 130%.

Step 3 - Now, let the original price of the TV be 'x'.

Step 4 - So, the value of 'x' is:

[tex]x = \dfrac{100}{130}\times 845[/tex]

Step 5 - Simplify the above expression.

[tex]x = \dfrac{8450}{13}[/tex]

[tex]x = 650[/tex]

So, the original price of the TV prior to the increase is £650.
