# Could somebody please answer these three questions with simple yet explanatory answers?

Answer: This is for #11 and #12.
First lets find the lateral area of each triangle. We will use thefollowing formula:-
lateral area = 4 (1/2 * base * slant height)
11. LA = 4 (1/2 * 8cm * 7.5 cm)
= 120 cm^2

12. LA = 4 (1/2 *14 in * 12in ) =
LA = 336 cm^2
Nowlets find the surface area:-
surface area = lateral area + area of the base
11. S.A. = 120 cm^2+ 8 * 8
= 120 cm^2 + 64

= 184 cm^2
S.A. = 336 cm^2+ 14 * 14
12.     = 336 cm^2 + 196

= 532 cm^2

LateralArea:-
11. 120 cm^2
12.
336 cm^2
SurfaceArea:-
11.
184 cm^2
12. 532 cm^2

Equation for 14+ W= 26

Answer: w = 12

Step-by-step explanation: In this problem, we want to get w by itself on one side of the equation. Since we have 14 + W, in order to get w by itself, we must subtract 14 from the left side of the equation.

If we subtract 14 from the left side of the equation, we must also subtract 14 from the right side of the equation. So on the left, +14 and -14 cancel each other and on the right, 26 - 14 simplifies to 12 so w = 12.

To check our answer, we substitute a 12 back in for w in the original equation and we have 14 + (12) = 26 or 26 = 26 which is a true statement so the answer checks.

Which of these pairs of points defines a line with a slope -4/3?A) (-1, 6) and (-4, 10)
B) (6, -1) and (-4, 10)
C) (-1, 6) and (10, -4)
D) (6, -1) and (10, -4

The point pair establishing a line with a slope of -4/3 is  (-1, 6) and (-4, 10). which is the correct answer would be an option (A).

### What is the slope of the line?

The slope of a line is defined as the gradient of the line.

To determine the slope of a line, we can use the formula: slope m = (y₂ - y₁)/(x₂ -x₁ )

Using this formula, we can calculate the slope for each of the pairs of points given:

A) (-1, 6) and (-4, 10):

slope = (10 - 6)/(-4 - (-1)) = -4/3

B) (6, -1) and (-4, 10):

slope = (10 - (-1))/(-4 - 6) = -11/10

C) (-1, 6) and (10, -4):

slope = (-4 - 6)/(10 - (-1)) = -10/11

D) (6, -1) and (10, -4):

slope = (-4 - (-1))/(10 - 6) = -3/4

Therefore, the pair of points that defines a line with a slope of -4/3 is (-1, 6) and (-4, 10).

Plz help me with 3 through 5 show ur work

The equation to find the volume of a pyramid is V=
3.)  V=  → Multiply the top V= → Divide by 3 V=
4.)  V= → Multiply the top V= → Divide by 3 V=59.904 or V=59.9
5.)  Since you need to find h you put the V value in and keep the h value blank. 1,350= → 1,350= → Multiply 3 by both sides 3×1,350=×3 → 4,050=225×h → Divide 225 from both sides 4,050÷225=225×h÷225 → 18=h

I hope that helps!

A major league baseball player hits 70 homeruns in 162 games.create a unit rate for this questionidk whata. unit rate is

--  (162 games) / (70 homers)  =  average of 2.314 games per home run.

--  (70 homers) / (162 games)  =  average of 0.432 home run per game.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates
to find the unit rate of this problem you divide 162 by 70 which is 2.31

Determine the value of impulse from this graph of momentum vs time
