Answer:
<u>The lengths of side A is 22.4 and B is 11.9</u>.
Step-by-step explanation:
Given:
If side A is twice as long as B and C is 25 using the Pythagorean Theorem.
Now, to find the lengths of side A and B.
Let the side B be 
So, the side A be 
Side C = 25.
Now, to solve by using Pythagorean Theorem:
A² + B² = C²
<em>Dividing both sides by 5 we get:</em>
<em>Using square root on both sides we get:</em>
<u>B rounding to the nearest tenth = 11.9.</u>
Now, to get A by substituting the value of 
:
<u>A rounding to the nearest tenth = 22.4.</u>
Therefore, the lengths of side A is 22.4 and B is 11.9.
Answer:
x = -11/9
Step-by-step explanation:
7(x+3)=-2(x-5)
Distribute
7x+21 = -2x+10
Add 2x to each side
7x+21 +2x = -2x+10+2x
9x +21 = 10
Subtract 21 from each side
9x +21-21 = 10-21
9x = -11
Divide each side by 9
9x/9 = -11/9
x = -11/9
Start with y = mx + b. Subst. -34 for m and 5 for b: y = -34x + 5
Answer:
cups plaster of paris.
Step-by-step explanation:
Given:
for one batch of sidewalk chalk = 
cup plaster of paris.
Number of bathes = 3
We need to find quantity of plaster of paris.
Solution:
For making 1 batch of sidewalk chalk = cup plaster of paris.
For making 3 batches of sidewalk chalk = 
cup plaster of paris.
Therefore, he needed cups plaster of paris.
