The answer is 12.92 in, 12 in, and 11.2 in
The area (A) of the triangle is:
A = s * a / 2
s - side
a - altitude
We know:
A = 84 in²
s1 = 13 in
s2 = 14 in
s3 = 15 in
a1 = ?
a2 = ?
a3 = ?
_______
a1 = ?
A = s1 * a1 / 2
84 = 13 * a1 / 2
84 * 2 = 13 * a1
168 = 13 * a1
a1 = 168 / 13
a1 = 12.92 in
_________
a2 = ?
A = s2 * a2 / 2
84 = 14 * a2 / 2
84 * 2 = 14 * a2
168 = 14 * a2
a2 = 168 / 14
a2 = 12 in
_______
a3 = ?
A = s3 * a3 / 2
84 = 15 * a3 / 2
84 * 2 = 15 * a3
168 = 15 * a3
a3 = 168 / 15
a3 = 11.2 in
Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:(7,6)
Equation Form: x=7, y=6
Answer:
9
Step-by-step explanation:
for every pie pua needs 3/4 cups of sugar
you can know this by dividing the sugar by the pies
then you can multiply 12 by 3/4 to find how many cups are needed for 12 pies, which is 9
Answer:
3/5 or 0.6 pounds.
Step-by-step explanation:
We would have to divide 1 1/4 by 3/4 to get the answer. We can convert 3/4 into 0.75 and 1 1/4 into 1.25 to get 0.75/1.25, which equals 0.6. Since 0.6 is the same as 3/5, the answer is 0.6 or 3/5 pounds of mashed pumpkin.
