Sid has a baseball cap collection. 65% of his caps have sports team symbols. If 26 of the caps have the team symbols, how many total caps does Sid have?

39
40
73
91

Answers

B. 40

As we know Sid has 26 Caps

we also know that 26 is 65% of total

so let total caps = x

to calculate x

we know that percent = (Values*100)/total Values.......... i

and here Value = 26 caps

percentage = 65

So we have

65 = (26*100)/x---------------- (As we know that per = fraction*100)..... from i

65x= 2600x = 2600/65x=40 caps

Hence Answer is 40

To make iced coffee, Sara puts her hot coffee into a refrigerator when it’s temperature is at 130 ℉ . The temperature of the coffee drops 4 ½ ℉ each hour. What is the temperature of the coffee after 5 hours?

PLEASE HELP I’M CONFUSED

Answers

To solve this all you need to do is multiply 4 1/2 x 5 and then subtract the Sun by 130°F. So 4 1/2×5 equals 22.5. 130-22.5=107.5. so the temperature of the coffee after five hours is 107.5°F.
If the coffee starts a 130 degrees and it cools if 4 1/2 degrees an hour and is in the fridge for 5 hours so 5 X 4 1/2 and that equals 22 1/2 so you would subtract 130 by 22 1/2 which would equal 107 1/2 degrees or 107.5 degrees

Every New Year's Day, Jennifer brings 13 candies for each of her grandchildren and 20 more candies for the adults to share.
Let g represent the number of Jennifer's grandchildren and c represent the total number of candies she brings.

Find the value of c when g=9.

Answers

Answer:

We can use the given information to set up a system of two equations:

c = 13g + 20

c - 13g = 20

The second equation is obtained from the first equation by subtracting 13g from both sides.

To solve this system, we can use substitution.

First, we solve the second equation for c.

c = 20 + 13g

Then, we substitute this expression for c into the first equation.

20 + 13g = 13g + 20

Then, we simplify.

20 = 20

So, the value of c when g = 9 is 20 + 13 * 9 = 20 + 117 = 137.

Step-by-step explanation:

C=137 because if you use the equation 13(7) + 20 you will get 137 candies.

Answer is y=6x

Explanation


When you have a graph, you can find the slope or coefficient next to x, by finding rise over run on the graph or using slope formula.

On the graph, from 0, 0, we go up or rise +6 and go right or run +1. Slope is 6/1 or 6.

Or, you have (0, 0) and (1, 6) as two definite points. Using slope formula
y2 - y1 over x2 - x1

6 - 0 over 1 - 0 = 6/1 or slope of 6.

Y=6x I think. Have a good day

Tell whether ratios form a propotion
1/4; 3/12
54/10; 81/15
18/24; 15/20
someone help me pls:(

Answers

Answer: Ratios form a proportion if they are equal when cross-multiplied.

1/4 and 3/12

Cross-multiply these ratios to compare them: 1/4 * 12 = 3, 3/12 * 4 = 3.

So they are equal and form a proportion.

54/10; 81/15

Cross-multiply these ratios to compare them: 54/10 * 15 = 81, 81/15 * 10 = 54.

So they are equal and form a proportion.

18/24; 15/20

Cross-multiply these ratios to compare them: 18/24 * 20 = 15, 15/20 * 24 = 18.

So they are equal and form a proportion.

Hence, all the ratios mentioned above form a proportion.
