An arcade charges for admission and tokens. Admission and 3 sets of tokens costs $50. Admission and 5 sets of tokens costs $80. What is the price of admission (initial value)?

A) $15

B) $5

C) $8

D) $3

_____________________________________

Answer: B) $5

1 Token Costs: $15.00

Admission Costs: $5.00

_______________________________

$15.00 × 5 = $75.00

$75.00 + $5.00 = $80.00

_______________________________

$13.00 × 3 = $45.00

$45.00 + $5.00 = $50.00

What is the measure of x°? 1. 90° 2. 101° 3. 114° 4. 111°

Ivenika [448]

Answer:

114

Step-by-step explanation:

The 5 angles equal 540, so subtract the 4 angles and you are left with 114.

540-111-103-122-90=114

Carissa also has a sink that is shaped like a half-sphere. The sink has a volume of 3000

defon

Answer:

a) 80
b) 56

Step-by-step explanation:

a) Calculate the volume of the the cup using volume of cylinder equation: $V = \pi r^{2} h$

Where V = Volume, r=radius, and h=height. Your answer should be in cubic inches ( $in^3$ ).
You're given diameter, so use equation $d/2 = r$ to find radius.
Substituting these equations will give you: $V = \pi (d/2)^2 h$
However, the given volume of the sink is 3000 $\pi$ , meaning that you should modify your results to match this value. Do not substitute $\pi$ for 3.14..., leave it as a symbolic value. Your final V of the cup should = 37.5 $\pi$
Divide the volume of the sink by the volume of the cup. This number will be the amount of cups needed to empty it. In equation form:
$Vsink / V cup =$ # of cups.
Note the the $\pi$ will cancel each other out, so there's not need to factor that in.
b) Repeat the steps above with the new d (diameter) value.
