Select all shapes that have a volume of 36pi cubic units.

Answer:

Step-by-step explanation:

The area of this figure is a sum of areas of a rectangle 5 m × 21 m and a triangle with base of 21 m and hight of 4 m.

A = 5×21 + 0.5×21×4 = 105 + 42 = 147 m²

Answer:

52.5 feet

Step-by-step explanation:

3.5x2.5x2=52.5

Answer: v+6*8*2 = 96

v = 6*8 = 48

5.5-2 = 3.5

48*3.5 = 168

168/2 = 84

96+84 = 180

The volume is 180 feet.

Answer:

1.3%

Step-by-step explanation:

Phat = 0.53

1 - phat = 1 - 0.53 = 0.47

Sample size, n = 5913

Assume the confidence level = 95%

Zcritical at 95% = 1.96

Margin of Error = Zcritical * √(phat(1 -phat)) / n

Margin of error :

1.96 * √((0.53 * 0.47) / 5913)

1.96 * 0.0064905

= 0.0127215

= 0.0127215 * 100%

= 1.272%

= 1.3%

Answer:

6

Step-by-step explanation:

Remark

This is one of those things that when you see it, you think that really is something.

The trick is to subtract a smaller right triangle from a larger one.

The base for both triangles is 4 (going from where the right angle is to your right where the lines of the red enclosure meet.

Calculations

The height of the larger triangle is 8

The height of the smaller triangle is 5

Area_L = 1/2 8 * 4 = 1/2 * 32 = 16

Area_S = 1/2 5 * 4 = 1/2 * 20 = 10

Red area = 1/2 * 32 - 1/2*20 = 16 - 10 = 6 units

Answer:

D: 14q + 21√qr

Step-by-step explanation:

We want to find the product of;

(2√q + 3√r) and 7√q.

Where p and q are integers.

Using distributive property, we have;

(2√q × 7√q) + (3√r × 7√q)

>> 14q + 21√qr

Correct option is D

Answer:

A). 9/5

Step-by-step explanation:

To find the slope, plug the values of x and y into the slope formula.

y2 - y1 / x2 - x1

-16 - 2 / -10 - 0

9/5

Better yet, let y = 6 and solve for x.

6 = x^2 –2x + 5

Now solve for x.

Answer:

D

Step-by-step explanation:

Given

n² - n - 42

Consider the factors of the constant term (- 42) which sum to give the coefficient of the n- term (- 1)

The factors are - 7 and + 6 , since

- 7 × + 6 = - 42 and - 7 + 6 = - 1 , then

n² - n - 42 = (n - 7)(n + 6) ← in factored form

Solution :-

Given,

We need to factorise it.

So let's start !!

Two factors are -7 and 6.

Therefore,

Answer:

90kg

Step-by-step explanation:

it is so because, to decrease a number by a ratio you have to multiply with the smallest number and divide with the biggest one. For example 117 in the ratio 7:3. 117×3=351 which is divided by 7 and is equal to 50.14.

The value 117kg decreased in the ratio 10:13 will be 90kg

Given the ratio 10:13. To reduce 117kg in this ratio, we will follow the steps:

Step 1: Multiply 117 by the smallest value

117 * 10 = 1170

Step 2: Divide the result by the largest value to have:

Value = 1170/13

Value = 90kg

Hence the value 117kg decreased in the ratio 10:13 will be 90kg

Answer:

2x + 3

Step-by-step explanation:

So, the equation here is:

[tex]\frac{2x^2 - 5x - 12}{x - 4}[/tex]

And so, using this we can set up our synthetic equation using the dividends as the coefficients of the equation, which are 2, -5, and -12; and the divisor 4, which derives from -4.

It's a bit hard to create a table here, so I'll just write out the values and hope you piece it together.

4 | 2 -5 -12

  | 2  8  12

   2   3  0

Thus, we are given our coefficients for our desired equation.

2x + 3

And we can ascertain this to be the answer by working the converse.

(2x + 3)(x - 4)

2x² - 5x - 12
