Antonio’s pizza charge $8.00 for a large pizza and $1.50 for each topping zine’s pizzeria charge $10.00 for a large pizza and $1
hichkok12 [17]
In this problem you would set these two equations equal to each other.
$8+ $1.50x = $10+ $1x 
After this you would simplify the equation to isolate x (being the number of toppings you put on the pizzas) 

$8+ 1.50x =$10+ 1x
-8              -8
----------------------------
$1.50x = $2 + $1x
-1x             -1x
--------------------------- 
$.50x/.50 = $2/.50
_______________
x= 4 toppings and the pizzas would equal $14 total

A Ferris wheel rotates 9π/8 radians prior to making a stop. The total height of the Ferris wheel is 246 ft. How far around did t
WARRIOR [948]

Answer:

The ferris wheel travelled 434.717 ft.

Step-by-step explanation:

Assuming that the ferris wheel is a perfect circle, then it's height is the same as the diameter of the circle, therefore it's radius is:

radius = height/2 = 246/2 = 123 ft

The distance travelled by the ferris wheel is the same as the length of the arc created by a angle of (9pi/8). The length of an arc is given by:

length = r*(angle in radians)

length = 123*(9pi/8)

length = 434.717 ft

The ferris wheel travelled 434.717 ft.

Monthly water bills for a city have a mean of $108.43 and a standard deviation of $36.98. Find the probability that a randomly s
GaryK [48]

Answer:

The bill size can be considered usual.

Step-by-step explanation:

Mean (μ) = $108.43

Standard deviation (σ) = $36.98

Now, consider the distribution to be normal distribution :

P(Z=\frac{X-\mu}{\sigma}>\frac{a-\mu}{\sigma})=P(Z>\frac{173-108.43}{36.98})\\\\\implies P(Z>1.75)

Now, finding values of z-score from the table. We get,

P(Z > 1.75) = 0.9599

⇒ 95.99%

So, only 4.01 % of the people in the city wastes water.

Hence, the bill size can be considered usual.
