Anyone know this as well?

Answer:

24.08

Step-by-step explanation:

We use the Pythagorean theorem and we get (16)^2 + (18)^2 = (x)^2

256 + 324 = x^2

x^2 = 580

x is about 24.08.

Answer:

the answer would be 35.7 the reason why is because your multiplying the width by its heigh  

Step-by-step explanation:

4.2x8.5=35.7

Answer:

0,15/ 5,20/ 10,25/ 15,30/ 25,35

Step-by-step explanation:

the additional hours is x and total hours is y.

Answer:

-3/20

Step-by-step explanation:

Let other number = x

∴ -9/20 + x = -3/5

∴ x = -3/5 + 9/20

∴ x = -3/20

Hope this helps  :) !!!!

Answer:

[tex]-\frac{3}{20}[/tex]

Step-by-step explanation:

GIVEN :-

TO FIND :-

SOLUTION :-

Let the another rational number be 'x'.

According to the question , the equation formed will look like this :-

[tex]x + (-\frac{9}{20} ) = -\frac{3}{5}[/tex]

[tex]=> x - \frac{9}{20} = -\frac{3}{5}[/tex]

Now solve the equation.

[tex]=> x - \frac{9}{20} + \frac{9}{20} = -\frac{3}{5} + \frac{9}{20}[/tex]

[tex]=> x = \frac{9}{20} - \frac{3}{5} = \frac{9 - (3 \times 4)}{20} = \frac{9 - 12}{20} = \frac{-3}{20}[/tex]

Answer:X=(-2,3) or X= (0,0)

Answer:

x = 7 and x = 5

Step-by-step explanation:

12x - 35 = x²

x² - 12x + 35 = 0

(x - 7)(x - 5) = 0

x = 7 and x = 5

Answer:

h = 4cm

Step-by-step explanation:

Diameter = 18cm

Radius = Diameter/2 = 18/2 = 9cm

V = 1/3*pi*r^2*h

We know that the volume is 108pi cm^3. We can just plug in 108pi cm^3 for V and we also know that our Radius (r) is 2.

So,

108 pi = 1/3*pi*9^2*h

108 pi = (81pi*h)/3

multiply 3 from both side

108pi*3 = (81pi*h)/3 *3

324pi = 81pi*h

Now divide the 81pi from both side

324pi/81pi = (81pi*h)/81pi

4 = h

So the height is 4cm

Answer:

h = 4cm

Step-by-step explanation:

Diameter = 18cm

Radius = Diameter/2 = 18/2 = 9cm

V = 1/3*pi*r^2*h

We know that the volume is 108pi cm^3. We can just plug in 108pi cm^3 for V and we also know that our Radius (r) is 2.

So,

108 pi = 1/3*pi*9^2*h

108 pi = (81pi*h)/3

multiply 3 from both side

108pi*3 = (81pi*h)/3 *3

324pi = 81pi*h

Now divide the 81pi from both side

324pi/81pi = (81pi*h)/81pi

4 = h

So the height is 4cm

Answer:

x=-11

Step-by-step explanation:

14x-3x+16=7(x-4)

Distribute

14x-3x+16= 7(x) + 7(-4)

14x-3x+16=7x-28

Combine Like Terms

11x+16=7x-28

Combine like terms

4x+16=-28

Combine like terms

4x=-44

Isolate x

x=-44/4

Simplify

x=-11

Answer:

the answer is C

Step-by-step explanation:

the percent decrease is by 8 percent

Answer:

12 feet

Step-by-step explanation:

w = width

w+2 = length

w(w+2) = 8

w² + 2w - 8 = 0

(w+4)(w-2) = 0

w = -4   exclude because a length cannot be negative

w = 2

length = 2+2 or 4

P = 2(2)+2(4)

P = 4+8 or 12

Answer:

im assuming that we are solving for g. i got 8x^2-10x-3 over x

Step-by-step explanation:

1. gx^2=8x2−10x−3

then u divide both sides by x which gets u gx over x = 8x^2-10x-3 over x

i hope that makes sense and helps!

Answer:

n = 6

Step-by-step explanation:

Given the following data;

Sum of interior angles, S = 720°

Mathematically, the sum of the interior angles in a regular polygon is given by the formula;

S = 180(n - 2)

Where;

n is the number of sides.

S is the sim of the interior angles

720 = 180(n - 2)

720 = 180n - 360

180n = 720 + 360

180n = 1080

n = 6

Answer: The correct choice is letter C.

Step-by-step explanation:

Cosine = adjacent/hypotenuse

In this triangle, you are looking for angle degree of cos X.

When finding an angle degree, you must use the inverse of whatever trig ratio you are using. In this case, you would use [tex]cos^{-1}[/tex].

The adjacent side from x is 12 and the hypotenuse is 15.

So you form your trig ratio which is your answer.

[tex]cos^{-1}[/tex] [tex]\frac{12}{15}[/tex] = 0.80

Answer:

2/20

Answer:

Debit Office Supplies Expense: 15,066, Credit Office Supplies: 15,066

Step-by-step explanation:

Office Supplies Account started with a $4000 debit balance.

Apply the adjustment of the end of the year total. $4000-$2334 = $1666.

The company purchased supplies for $13,400

$13,400 + $1666 = $15,066

Answer:

[tex](0.17 - 0.27) \pm 1.65\sqrt{\frac{0.17*0.83 + 0.27*0.73}{200}}[/tex], that is, option C

Step-by-step explanation:

From a random sample of 200 people in City C, 34 were found to subscribe to the streaming service. From a random sample of 200 people in City K, 54 were found to subscribe to the streaming service.

This means that the proportions are:

[tex]p_C = \frac{34}{200} = 0.17[/tex]

[tex]p_K = \frac{54}{200} = 0.27[/tex]

Subtraction of proportions:

In the confidence interval, we subtract the proportions. So:

[tex]p = p_C - p_K = 0.17 - 0.27[/tex]

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

Standard error:

For a subtraction, as the standard deviation of the distribution is the square root of the sum of the variances, we have that:

[tex]\sqrt{\frac{\pi(1-\pi)}{n}} = \sqrt{\frac{0.17*0.83 + 0.27*0.73}{200}}[/tex]

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

So the confidence interval is:

[tex](0.17 - 0.27) \pm 1.65\sqrt{\frac{0.17*0.83 + 0.27*0.73}{200}}[/tex], that is, option C

Answer:

130.81

Step-by-step explanation:

127 ⋅ ( 103/ 100 ) =130.81

Answer:

D, or 150

Step-by-step explanation:

We can see that we have to multiply 6 by 30 to get 180. So, if we multiply the denominator by this and we want an equal fraction, we can multiply 5 by 30 to get [tex]5\cdot30=150[/tex].

Answer/Step-by-step explanation:

I think its "D. 150"!

Answer:

You have 16 different toppings

Step-by-step explanation:

Given

[tex]Sameer = 12[/tex]

Required

How many topping at your sundae shop

From the question, we understand that Sameer's is3/4 of your toppings

Mathematically, this is:

[tex]Sameer = \frac{3}{4} * Y[/tex]

Where

Y represents You

Make Y the subject

[tex]Y = \frac{4}{3} * Sameer[/tex]

Substitute 12 for Sameer

[tex]Y = \frac{4}{3} * 12[/tex]

[tex]Y = 4 * 4[/tex]

[tex]Y = 16[/tex]

Answer:

Pvalue = 0.193

There is not enough evidence to conclude that the proportion of registered organ donors is less than 40%

Step-by-step explanation:

H0 : p = 0.4

H1 : p < 0.4

Test statistic :

z=pˆ−p/√p(1−p)/n

pˆ = 74 / 200 = 0.37

Z = (0.37 - 0.40) / √(0.40(1 - 0.40) / 200

Z = - 0.03 / √0.0012

Z = - 0.03 / 0.0346410

Z = - 0.866

Test statistic = -0.866

The Pvalue :

P(Z < -0.866) = 0.193

α - level = 0.05

If Pvalue < α ; Reject H0

Since Pvalue > α ; There is not enough evidence to conclude that the proportion of registered organ donors is less than 40%
