Step-by-step explanation:
PART C; The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:
-$23.50.
Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is
-$23.50 – (-$23.50 × 0.2).
Further simplify the expression by factoring -$23.50 from both terms:
-$23.50 – (-$23.50 × 0.2)
=
-$23.50(1 – 0.2)
=
-$23.50(0.8).
The net change to her banking account balance is $83.22.
What is net change?The net change theorem states that when a quantity changes, the final value equals the initial value plus the integral of the rate of change. Net change can be a positive number, a negative number, or zero.
Given that, She spent $36.50 plus 8% tax. (to calculate the tax amount, we have to multiply the cost by the percentage in decimal form)
36.50 x (8/100) =$2.92 (value of tax)
Adding to the original cost
36.50+2.92 = $39.42
Then, she spent $25 to refuel her car at the gas station.
39.42 +25 = $64.42
She bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase
23.50 x (20/100) = 4.7 (amount of discount)
Subtracting to the purchase
23.50 -4.7= $18.8
Hence, adding to the total cost.
64.42 +18.8 = $83.22

Answer:
Students in 7th grade took a standardized math test that they also had taken in 5th grade. The results are shown on the dot plot, with the most recent data shown first.
Find and compare the means to the nearest tenth.
7th-grade mean:
✔ 16
5th-grade mean:
✔ 13.4
What is the relationship between the means?
✔ The 7th-grade mean is about 2.5 points higher.
Step-by-step explanation:
Mean for 7th Grade Students is: 16
Mean for 5th Grade Students is: 13.4
Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.
What is the Mean of a Data Distribution?The mean is the average of the data set, that is the sum of each data value divided by the number of data points.
Given that, 7th Grade Students in 7th grade took a standardized math test that they also had taken in 5th grade.
Mean for 7th Grade Students:
Mean = [10 + 11 + (2 × 12) + 13 + 14 + (2 × 15) + (3 × 16) + (3 × 17) + (2 × 18) + (2 × 19) + (3 × 20)]/21
Mean = 335/21
Mean = 15.95 = 16
Mean for 5th Grade Students:
Mean = [8 + (2 × 9) + (2 × 10) + (2 × 11) + (2 × 12) + (2 × 13) + 14 + (3 × 15) + (2 × 16) + 17 (2 × 18) + 19
Mean = 281/21
Mean = 13.38 = 13.4
The difference between their means = 16 - 13.4 = 2.6.
Hence, Mean for 7th Grade Students is: 16
Mean for 5th Grade Students is: 13.4
Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.

First, let's find the area of A and C
5 ✕ 12 = 60

Then B
8 ✕ 12 = 96
Then the triangles
3 ✕ 5 ÷ 2 = 12 / 2
But now think,because there are 2 triangles, so we have to times it by 2 later so we can just leave it like this.
