The midsegment is half the length of the base. So the base = 2*4 = 8 in.
Since it is an isosceles triangle, the other two sides are equal in length.
Perimeter = sum of two equal sides + base = 20 in.
2x equal side + 8 = 20
equal side = 12/2 = 6
Each of the equal sides = 6"
To answer this question, make a setup like this;

multiply across, and your answer is 1/15.
Is the picture supposed to have a black line
Answer:
Step-by-step explanation:
Work can be found by multiplying the force by the distance traveled in the direction of the force.
The force is 45 Newtons.
The distance traveled is 1 meter.
Substitute the values into the formula.
Multiply.
1 Newton meter is equal to 1 Joules.
Therefore our answer of 45 Newton meters is equal to 45 Joules.
The work done is <u>45 Joules.</u>
1 gallon = 16 cups. She is making 2 gallons so needs 32 total cups.
The ratio is 4:3:1
Add the ratios: 4+ 3 + 1 = 8
Divide total cups by total ratio:
32/8 =4
Now multiply that by each portion of the ratio:
Grape juice = 4 x 4 = 16 cups
Pineapple juice = 3x4 = 12 cups
Cider = 1x 4 = 4 cups
She needs 12 cups of pineapple juice.
