Step-by-step explanation:

square-based pyramid:

volume V = (⅓)b²h

    = (⅓)7²·16  

    ≅ 261.3 ft³

Can't help with question 3. I haven't learned triangle-based pyramids.

:::::

cone:

volume V = ⅓πr²h

              = ⅓π17²·20

              = 6052.8 yd³

Answers

Answer:

8 hours

Step-by-step explanation:

t = time for Bob and Nina to make 60 leashes

Bob = 7 in 2 hr  = 3.5 in 1 hr

Nina = 4 in 1 hr

3.5 + 4 = 7.5 leashes per hour

Help me to find the value of x, please

Answers

Add all the values and set them equal to 180. This is because they make a straight angle. So...

15x + 90 + 8x-2 = 180
23x + 88 = 180
23x = 92
x = 4

Answer:

x = 4

Step-by-step explanation:

The easiest way to do this is to look at the vertical angles. (15x)º has its own vertical angle, and the part with (8x-2)º and 90º does as well.

Also, every angle will add up to 360º, which is a crucial part of the equation

Do 15x + 15x + 90 + 90 + 8x - 2 + 8x - 2 = 360

This can be simplified into this once you combine like terms:

46x + 176 = 360

Subtract 176 from 360, which will give you:

46x = 184

Divide by 46 on both sides, resulting in:

x = 4

To check the answer, plug in 4 for x:

15(4) + 15(4) + 90 + 90 + 8(4) - 2 + 8(4) - 2 = 360

60 + 60 + 90 + 90 + 32 - 2 + 32 - 2 = 360

120 + 180 + 60 = 360

360 = 360, x is 4

Hope this made sense!

2/5 of a number is -8 what is the number

Answers

Answer:

-20

Step-by-step explanation:

let x be the whole. 2/5 of x = -8 so -8 1/5 is -4. -4*5 to find the whole so its -20

Answer: The number is 35

If 2/5 of a number is 14, then we will perform a function of cross multiplication in order to determine the missing number.

Step-by-step explanation:

Let the missing number = y

To perform a cross multiplication, firstly, we multiply the numerator of first fraction by the denominator of the second fraction.

Secondly, we multiply the denominator of the first fraction by the numerator of the second fraction. Then, the resulting values are divided by each other to get a final numerical value.

Therefore, the missing number (y) will the denominator of the second fraction i.e. 14/y . The first fraction is 2/5.

Thus,

2/5 of 14/y

2/5= 14/y

(2 x y) = (5 x 14)

(2y) = (70)

2y = 70

Since we are looking for value of y, divide both sides by the value beside y

Thus,

2y/2 = 70/2

y = 35

Therefore, the missing number is 35

Answers

Answer:

y = -1/3

x = 0

Step-by-step explanation:

3x-6y = 2    then 3x = 2+6y,   x=(2+6y)/3

4x+3y = -1

substitute for x

4(2/3+2y)-6y = 2

8/3+8y-6y = 2

reduce

2y = 2-8/3

2y = -2/3

divide both sides by 2

y = -1/3

4x+3(-1/3) = -1

4x = 0

x = 0
