$1.80


54×\frac{1}{3}=18

54×0.30=16.2


18-16.2=1.8

Answer:

Option B - 1.8$

Step-by-step explanation:

She gets skirt at 54$

Though she got discount = 30%

This clearly indicates that she safe 30% from her purchase,

Calculation,

54 * 30 / 100 = 16.20$

However, her friend told to get discount 1 / 3 of 54

This means 54 / 3 = 18

We subtract both discounts to each other like the following,

18 - 16.20 she will get more discount about 1.8$

Ultimately the answer would be B.

find the average rate of change from t=2 to t=5 for the velocity function v(t)=t^2-t+10. WILL GIVE THE BRAINLIEST ANSWER--EXPLAI
Elina [12.6K]
Answer: The average rate of change is 6.
First, plug in each value of <em>t</em> into the function, v(t) to find there coordinate pairs.

v(2) = (2)^2 - (2) + 10
v(2) = 4 + 8
v(2) = 12

v(5) = (5)^2 - (5) + 10
v(5) = 25 + 5
v(5) = 30

You can write these values as coordinate pairs, like so: (2, 12) and (5, 30).
The formula for the average rate of change is A(x) =  \frac{f(x)-(f(a)}{x-a}. When you plug in the values from this particular case, the average rate of change formula becomes A(t) = \frac{30-12}{5-2}, or A(t)= \frac{18}{3}.

Looking at the equation, you can solve for the average rate of change between t = 2 and t = 5, which equals 6.

Mrs. Avery's class ate 1/5 of their green pepper pizza and 9/12 of their pepperoni pizza. Which pizza did they eat more of?
Anton [14]
So what you have to do is make the denominators equal. You do that by finding out what number they can both go into which is 60. 12 can go into 60 5 times and so you have to do 9/12 times 5 which is 40/60. then 5 goes into 60 12 times so you have to do 1/5 times 5 which is 12/60. Then you see that 40/60 >12/60 therefore the class ate more of the pepperoni pizza
