s2008m [1.1K]

The 32,500 is the original cost of the truck and the (0.92) You take v(x)=32,500(0.92)
and raise that to the 2nd power, to represent the 2nd year and you will get an answer of $27,300.
Each year the truck is losing $2,600 in value, after two years the truck has lost $5,200 in value equalling

18.4b=44.16 need help fast

MaRussiya [10]

Answer:

<u>If it's 18.4b=44.16:</u> $b=2.4$

<u>If it's 4b=44.16:</u> $b=11.04$

Step-by-step explanation:

<u>If it's 18.4b=44.16:</u>

$18.4b=44.16\\\\\frac{b}{18.4}=\frac{44.16}{18.4}\\\\b=2.4$

<u />

<u>If it's 4b=44.16:</u>

<u /> $4b=44.16\\\\\frac{b}{4}=\frac{44.16}{4}\\\\b=11.04$ <u />

HELP PLEASE!!!!!!!!

The angles of a triangle add up to 180 degrees

180 - 80 = 100

Both of the unknown angles are the same. So...

100/2= 50

X = 50 degrees

Please help me i’ve tried so many of these and i can’t figure out how to do it

zheka24 [161]

Answer:

15.4%

Step-by-step explanation:

Calculate the volume of both containers.

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

$V_{A}$ = π × 10² × 11 = 1100π ft³

$V_{B}$ = π × 7² × 19 = 931π ft³

Subtract volume of B from volume of A to find quantity left in A

quantity left in A = 1100π - 931π = 169π ft³

To calculate the percentage left in A after B has been filled

$\frac{left}{full}$ × 100%

= $\frac{169\pi }{1100\pi }$ × 100%

= $\frac{169}{1100}$ × 100%

= 15.4% ( to the nearest tenth )
