PLSSS HELP, I need to figure out the answer to this with showing work included.

Answer:

I think it will be 400 cm^2

Step-by-step explanation:

8cm x 20cm/ 2 = 80cm^2  this is for the triangle

So the base is 20cm^2 and so me multiply that x2  which will give us 400cm^2 for the square

Answer:

13%

Step-by-step explanation:

Given the two way frequency table :

Country Music Rock Total

West 26 15 41

East 24 22 46

South 7 33 40

North 41 25 66

Total 98 95 193

From. The table :

n(West n Country music) = 26

n(Total) = 193

P(West n Country music) = n(West n Country music) / n(Total)

P(West n Country music) = 26 / 193

= 0.1347

= 13.47%

= 13%

Answer:

Distance cover by train = 112.5 km

Step-by-step explanation:

Given;

Speed of train = 75 km/h

Time started = 15:43 min

Time ended = 17:13 min

Find:

Distance cover by train

Computation:

Time started = 15:43 min = 15.716 hour

Time ended = 17:13 min = 17.216 hour

Total time taken = 17.216 - 15.716

Total time taken = 1.5 hour

Distance cover by train = Total time taken x Speed of train

Distance cover by train = 75 x 1.5

Distance cover by train = 112.5 km

Answer:

  (f/g)(8) = -104/41

Step-by-step explanation:

Fill in the value for x and do the arithmetic.

  f(8) = 3 -2·8 = 3 -16 = -13

  g(8) = 1/8 +5 = (1+40)/8 = 41/8

Then the ratio is ...

  (f/g)(8) = f(8)/g(8) = -13/(41/8) = -13(8)/41

  (f/g)(8) = -104/41

(B) The equation of line is 5 X = 2 Y.

Step-by-step explanation:

2 ounces of pineapple juice

5 ounces of fruit punch

Other is 4 ounces pineapple juice and 10 ounces fruit punch

(A) Graph is shown below:

(B) Let X is the pineapple juice and Y is the fruit punch

(2, 5)  and (4, 10)

So, the equation of line is

[tex]Y - 5 = \frac{10-5}{4-2}\times (x -2)\\\\Y-5=2.5 (X-2)\\\\Y - 5 = 2.5 X - 5 \\\\2.5 X = Y\\\\ 5 X = 2 Y[/tex]

Answer:

30 experimental outcomes exist for the entire experiment.

Step-by-step explanation:

Fundamental counting principle:

States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.

In this question:

Three outcomes possible for the first step.

Two for the second step.

Five for the third step.

How many experimental outcomes exist for the entire experiment?

Steps are independent, so, by the fundamental counting principle:

3*2*5 = 6*5 = 30

30 experimental outcomes exist for the entire experiment.

Answer:

[tex]x^3[/tex]

Step-by-step explanation:

Let the greatest common factor of [tex]a,b,c[/tex] such that [tex]a,b,c \in\mathbb{Z}[/tex] and they are not all equal to zero, [tex]d[/tex] is the common divisor of [tex]a[/tex] and [tex]b[/tex]. Therefore, [tex]d \mid a[/tex] and [tex]d \mid b[/tex]

You can write

[tex]D(a) = \{d \in\mathbb{Z} : d \mid a\}[/tex]

[tex]D(b) = \{d \in\mathbb{Z} : d \mid b\}[/tex]

The greatest common factor of [tex]a,b[/tex] is given as

[tex]D(a,b) = \{d \in\mathbb{Z} : d \mid a \text{ and } d \mid b\}[/tex]

and

[tex]D(a, b) = D(a) \cap D(b)[/tex]

This happens because [tex]D(a,b)[/tex] is upper bounded because if [tex]a\neq 0[/tex] then [tex]d \leq |a|[/tex]

for all [tex]d\in D(a, b)[/tex]. Therefore, the set [tex]D(a, b)[/tex] has the greatest elements.

Taking [tex]x^3, x^7, x^9[/tex] such that [tex]x>0[/tex]

You can note that [tex]x^7 = x^3 \cdot x^4[/tex] and [tex]x^9 = x^3 \cdot x^6 = x^3 \cdot x^3 \cdot x^3[/tex]

Therefore, the greatest common factor is [tex]x^3[/tex]

Note: [tex]x^3 \cap x^7 \cap x^9 = x^3[/tex]

Answer:

B. HL

Step-by-step explanation:

Answer:

B.  8.384 to 11.616

Step-by-step explanation:

We have

mean = 10

s = 4

n =  26

the degrees of freedom = n-1

= 26 - 1 = 25

α = 1-95%

= 1 - 0.95

= 0.05

α/2 = 0.05/2 = 0.025

using the t table

t0.025, 25 = 2.06

we find the margin of error

t * s/√n

= 2.06 * 4/√26

= 1.616

10-1.616 < μ < 10+1.616

= 8.384<μ<11.616

therefore option b is the right solution

Answer:

  y(x(t)) = -4t^2 -8t -5

Step-by-step explanation:

Fill in the argument value and simplify.

  y(x(t)) = y(t^2 +2t) = -4(t^2 +2t) -5

  y(x(t)) = -4t^2 -8t -5

Step-by-step explanation:

Given that,

x=4y - 12 ....(1)

And

-2y= x- 6 ....(2)

Put equation (1) in equation (2). So,

-2y= (4y - 12)- 6

-2y = 4y - 12 -6

-2y-4y = -12-6

-6y = -18

y = 3

So, substituting x=4y - 12 into the equation -2y= x- 6 will produce y = 3.

Answer:

- 31

Step-by-step explanation:

4(3 − 2) − 7(5)

Subtract 3 - 2

4(1) - 7(5)

Multiple -7 and 5

4 - 35

Subtract 4 - 35

The correct answer is -31.

The simplified form of 4(3 − 2) − 7( + 5) is -31.

To simplify the given expression, using (PEMDAS/BODMAS) and simplify each part step by step.

4(3 − 2) − 7( + 5)

First, simplify the expressions inside the parentheses:

3 − 2 = 1

+ 5 = 5

then, the expression becomes:

4(1) − 7(5)

Next, let's perform the multiplications:

4(1) = 4

7(5) = 35

The expression now becomes:

4 − 35

Finally, let's perform the subtraction:

4 − 35 = -31

Therefore, the simplified form of 4(3 − 2) − 7( + 5) is -31.

Answer:

12 units

Step-by-step explanation:

From the given figure,

AB=4 units & BC=3 units

By Pythagoras Theorem, [tex]AC^{2} = AB^{2} + BC^{2}[/tex]

Here, [tex]AC^{2} = 4^{2} + 3^{2}[/tex]

Thus, AC=5 units

Now, perimeter of triangle is equal to the sum of all sides.

Perimeter = AB + BC + AC = 4 + 3 + 5 = 12 units

Answer:

2 pipes

Step-by-step explanation:

So.. I'm not too sure either, but I'll try to solve it.

Equation: 4x=8 when x=number of pipes turned off after 12 hours

Since there were initially 8 pipes and there are 4 hours between 36 planned hours to fill the whole pool and 32 actual hours passed to fill the rest of the pool, you multiply them.
