Answer:

26.7pounds

Step-by-step explanation:

Suppose that an individual has a body fat percentage of 15.9% in weighs 168 pounds

This is calculated as:

Pounds of his weight that is made up of fat is calculated as

Body fat percentage × Body weight in pounds

= 15.9% × 168 pounds

= 15.9/100 = 168 pounds

= 26.712 pounds

Approximately to the nearest tenth = 26.7 pounds

Answer:

y = 1 , x = 3

Step-by-step explanation:

3x + y = 10

x = 2y + 1

3(2y + 1) + y = 10

6y + 3 + y = 10

7y = 7

y = 1

x = 2(1) + 1

x = 3

Answer:

The volume of the given figure is 150 mm³

Step-by-step explanation:

The formula of the volume of the triangular pyramid is V = [tex]\frac{1}{3}[/tex] AH, where

The formula of the area of a triangle is A = [tex]\frac{1}{2}[/tex] bh, where

In the given figure

∵ The pyramid has a triangular base

∵ The triangle has a base of 12 mm and a height of 7.5 mm

∴ b = 12 mm and h = 7.5 mm

→ By using the 2nd formula above, find the area of the base

∴ A = [tex]\frac{1}{2}[/tex] (12)(7.5)

∴ A = 45 mm²

∵ The height of the pyramid is 10 mm

∴ H = 10 mm

∵ A = 45 mm²

→ Substitute them in the first formula above to find the volume

∴ V = [tex]\frac{1}{3}[/tex] (45)(10)

∴ V = 150 mm³

∴ The volume of the given figure is 150 mm³

Answer:

y=-7x -2

Step-by-step explanation:

use formula to find the equation when you know slope and a point

it is: y-y1 = m(x-x1)

plug in values

y-(-30) = -7(x-4)

y+30 = -7x + 28

- 30 from both sides

y = -7x -2

Answer:

the first one

Step-by-step explanation:

Answer:

I believe the answer is C

Answer:

Slope = 8 Y-intecept = (0, 3)

Step-by-step explanation:

Slope-intercept form: y = mx + b

m = slope

b = y intercept value

y = 8x + 3

m = 8

y = 3

Answer:

Over time, mathematicians have developed a set of rules called the order of operations to determine which operation to do first. The rules are: Multiply and divide from left to right. Add and subtract from left to right.

Step-by-step explanation:

Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to perform multiplication and division from left to right. Next, add and subtract from left to right.

Answer:

You got to give me an qestion with numbers but hears how you do it.

Answer:

true

Step-by-step explanation:

To round off a number to its nearest whole number, look at the first number after the decimal point. If the number is equal or greater than 5, add 1 to the number before the decimal point. If it is  less than 5, add zero.

Because the first number after the decimal point is 3, which is less than 5, add zero to 16 . 16 + 0 = 16

If the number were 16.571, rounding off to the nearest whole number would give 17

Answer:

4 < x < 36;  values that apply are 5, 16, 20, 35

Step-by-step explanation:

use triangle inequality theorem:

the sum of any two sides is greater than the third

16 + x > 20;   x > 4

16 + 20 > x;   x < 36

Answer:

  see below

Step-by-step explanation:

The symbol ≤ means the dot at -9 will be solid, because the value -9 is part of the solution set. The line is shaded for values less than -9, because that is what the inequality is telling you are values of r that are in the solution set.

(A) You will have to finish the assignment yourselves.

Step-by-step explanation:

In B, C, and D, the "yourself" and "myself" words aren't adding any emphasis to the situation! But in sentence (A), the speaker is saying that, you will have to finish the assignment YOURSELF. No help from anyone else! (This implies that the task might be difficult, putting emphasis!)

Answer: 1/4

Step-by-step explanation:

A die has 6 figures which are 1, 2, 3, 4, 5 and 6. There are 3 even numbers which are 2, 4 and 6. A coin has 2 outcomes which are head or tail.

The probability of getting an even number is 3/6 = 1/2.

The probability of getting a head is 1/2.

Therefore, the probability of obtaining an even number and a head will be:

= 1/2 × 1/2

= 1/4
