Answer:
12.73 Degrees
Step-by-step explanation:
I'm going to assume some things. The height of the truck is not changing, i.e. the distance and length of the ramp are but the height stays the same.
We draw our right triangle, see photo*
We really only care about finding out what side a is so
So, since I stated that height did not change, the same process just using 32 for the hypotenuse.
Answer: (A) 10
<u>Step-by-step explanation:</u>
<u>Value</u> <u>Quantity</u> = <u>TOTAL Value</u>
dimes: .10 Q + 5 = .10(Q = 5)
quarters: .25 Q = .25Q
Dimes + Quarters = $4.00
.10(Q + 5) + .25Q = 4.00
.10Q + .50 + .25Q = 4.00
.50 + .35Q = 4.00
.35Q = 3.50
Q = 10
Quarters = 10
Dimes = Q + 5
= 10 + 5
= 15
What you have to do is solve for x of course stated above
4x - 2 + 5x + 10 = 2x +14
9x +8 = 2x + 14
(minus 2x from both sides)
7x + 8 = 14
(minus 8 from both sides)
7x = 7
(divide 7 from both sides)
x=1
Answer:
The surface area increases by 11.16 cm².
Step-by-step explanation:
First find the surface area of the original shape
A=2(wl+hl+hw) Use this equation to find the surface area of the rectangular prism.
A = 2[(4.6 x 14)+(32 x 14)+(32 x 4.6)] Multiply and add
A = 1319.2 cm²
Now increase the height by 0.3 cm
A = 2[(4.6 x 14)+(32.3 x 14)+(32.3 x 4.6)] Multiply and add
A = 1330.36 cm²
Subtract 1330.36 by 1319.2 = 11.16 cm²
