Answer:
148 inches
Step-by-step explanation:
1. You would want to split the rhombus into 4 right triangles.
2. You know two sides of the right triangles (One side would be 12 inches and the other 35) Knowing that you would use the Pythagorean theorem.
3. 35^{2}+12^{2}=c^{2}
4. Solve: 1225 + 144 = 1369
5. The square root of 1369 is 37
6. Multiply 37 x 4 (For all the sides of your triangles)
7. 148 inches
Answer:
x= 13.5
Step-by-step explanation:
f(x) = 2x + 9
f(x) = 36
Set the 2 equations equal to each other;
2x + 9 = 36
Subtract 9 from both sides;
2x = 27
Divide both sides by 2;
x = 13.5
<em>Check:</em>
f(x) = 2x + 9
f(13.5) = 2(13.5) + 9= 27 + 9 = 36
Answer:
h = 80
Step-by-step explanation:
Remark
The general Volume formula for a pyramid is V = 1/3 * B * h
Givens
base edge = 3 m
V = 240 m^2
Solution
V = 1/3 * B * h
B = s^2
B = base edge^2
B = 3^2
B = 9
240 = 1/3 * 9 * h multiply by 3
240 * 3 = 9 h Divide by 9
80 = h
Answer:
(5/2,-5)
Step-by-step explanation:
plug in zero for each of the variables to get the other one
2x-0=5
2x=5
x=5/2
2(0)-y=5
-y=5
y=-5
The answer to the question above is B.)
