To calculate the length of the diagonal, use the Pythagorean theorem:
c^2 = a^2 + b^2, where c is the diagonal.
c^2 = 65^2 + 34^2
c^2 = 4225 + 1156
c^2 = 5381
c ~ 73.36
To the nearest tenth of a meter, the diagonal has a length of 73.4 m
Answer:
-12
Step-by-step explanation:
Answer:
Step-by-step explanation:
9=-d+17
(add d to both sides because it is the opposite of subtracting)
9+d=17
(subtract 9 from both sides because it is the opposite of adding)
d=17-9=8
Start with
Subtract 
from both sides:
Divide both sides by 
And thus we solved the expression for l:
Answer:
70percent =42
100percent ×42 ÷70
100/7×42
10/7×42=60
therefore the original cost was $60
