13/11,24/13,11/13,11/24

Answer:

65:55, 55:65, 55:120

Step-by-step explanation:

Fiberglass boats are = 65 because 120-55=65

Fiberglass to wood means that there is a 65:55 ratio because there are 65 fiberglass boats and 55 wood boats

wood to other, this is kind of a trick question, but its 55:65 because there are 65 other boats and 55 wooden boats

wood to total, this is 55:120 there are 55 wood boats and 120 total boats.

Gina has been offered a job as a dog walker. Each week Gina works, she gets a flat amount of $10, plus an additional $5 per dog walked. Gina's goal is to earn at least $75 each week. Which inequality can be used to find the number of dogs Gina must walk in a week in order to reach her goal?

Answers

Answer:

Step-by-step explanation:

Given data

flat amount =$10

let the number of dogs walked be x

and let the money earned be y

y= 10+5x

for y= 75

let us find x

75= 10+5x

75-10= 5x

65= 5x

divide both sides by 5

x= 65/5

x=13

Hence the number of dogs is 13

Are these terms alike or unlike: 2xy and 2xyz

Answers

Answer:

Unlike

Step-by-step explanation:

When it comes to like terms, the numbers must have the same ending variable, 2xy and 2xyz do not have the same ending variable, which seeing it, one ends with 2xy and the other with 2xyz. Therefore these terms are not the same and the answer is unlike.

Answer:

unlike

Step-by-step explanation:

this is bc 2xy does have a z while 2xyz does

Renee bought 7 potatoes at the supermarket. The shortest diameter of each, in centimeters, is shown below. 2,3,,4,4 6,6,7 After Renee used one potato to make dinner, the median diameter of the remaining potatoes was 5 centimeters. Which of these could be the diameter, in centimeters, of the potato Renee used?

Answers

Answer:

2 cm, 3 cm or 4 cm

Step-by-step explanation:

Diameters of potatoes:

2, 3, 4, 4, 6, 6, 7

Median is:

4 cm

After one potato used the median becomes 5 cm.

Out of 6 potatoes left, the two in the middle should give 5 cm in average

This is 4 cm and 6 cm.

Renee must have used one of the 4 potatoes on the left: 2 cm, 3 cm or 4 cm

= P 500

3. The actual sits accommodated by the passengers is

= 60 sits ×50%

= 30 sits

Please do number 18 for me.

Answers

Step-by-step explanation:

angle S + angle W + angle STW = 180

(7x + 6) + (7x + 1) + angle STW = 180

So angle STW = 180 - (7x + 6) - (7x + 1)

angle STW + angle STP = 180 (straight angle = 180)

180 - (7x + 6) - (7x + 1) + angle STP = 180

angle STP = 180 - 180 + (7x + 6) + (7x + 1)

= 7x + 6 + 7x + 1

= 14x + 7

15x = 14x + 7

x = 7

angle STP = 15x = 15(7) = 105

Each wallet contained the name and address of the owner and either a photograph of a baby, a photograph of a puppy, a photograph of a young family, a photograph of an older couple, or no photograph. The researchers hypothesized that the type of photograph left in the wallet would influence the rate of return. The wallets with a photograph of the baby and the wallets with a photograph of the puppy were left early in the morning, the wallets with a photograph of the young family were left in the afternoon, and the wallets with either no photograph or a photograph of an older couple were left in the evening.
