Answer:
95.5°F
Step-by-step explanation:
Given the regression equation :
y = 1.8x - 76.9 ; the relationship between temperature (°F) and number of ice cream sold
y = number of ice cream sold
x = temperature (°F)
The temperature when 95 iccream cones are sold will be ;
Here, y = 95
Using the model :
95 = 1.8x - 76.9
95 + 76.9 = 1.8x
171.9 = 1.8x
Divide both sides by 1.8
171.9 / 1.8 = x
95.5°F = x
Hence, temperature when 95 cones of ice-cream are sold is 95.5°F
You just need to divide the given numbers to get the answer.

Question: Chad reads 30 pages in 3 hours. How many pages can he read in 1 hour.
Answer: 30/3=10
Therefore, Chad reads 10 pages in 1 hour.

Answer:
Step-by-step explanation:
The standard vertex form of a quadratic (which is what your graphs are) is
where h and are the coordinates of the vertex. The vertex is really all we need to fill in this equation. Looking at the blue graph, the vertex is located at (-4, 1), so h = -4 and k = 1. Filling in the equation:
which simplifies down to
. It's that simple.I think that's choice C (I'm not sure; it's very tiny!)
Bethany says, Using these exchange rates, £1 is worth 1.17 euros.
<u>Step-by-step explanation</u>
1 euro = 1.07 dollars
£1 = 1.25 dollars
Now ,
⇒ £1 = 1.25 dollars
⇒ £1 = 
⇒ £1 = 
⇒ £1 = 
⇒ £1 = 
⇒ £1 =1.17 euros
Therefore , Bethany says, Using these exchange rates, £1 is worth 1.17 euros.
