12 cubic inches

Step-by-step explanation:

The formula for the area of a triangle is : $\frac{base*height}{2}$

To work out the volume you would first need to work out the area of a triangle. you can do this by first multiplying base of 4 by the height of 3, this gives you 12.

The next step is to divide 12 by 2, this gives you 6. this is because the formula is the same for a square, however a triangle is half of a square with the same dimensions.

Now that you have worked out the area, to work out the volume you would

multiply the area of 6 by the width of 2, this gives you 12 cubic inches.

1) Multiply 4 by 3.

4*3=12

2) Divide 12 by 2.

12/2=6

3) Multiply 6 by 2.

6*2=12inches^3

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
