When you say that two numbers are relatively prime, it means that both numbers do not have a common factor except 1. Stephen is incorrect because 38 and 40 are both multiples of 2.

I hope I answered your question. Thank you J

Relatively prime numbers have a GCF of 1. The numbers 38 and 40 have a GCF of 2, so they are not relatively prime.

Veronica got 3 times as many gifts as Natalie. Together Veronica and Natalie got a total of 12 gifts. How many gifts did Natalie

umka21 [38]

Natalie = x

Veronica = 3x

Altogether 4x meaning 4 parts

12 divided by 4 = 3

Natalie got 3 gifts veronica got 9

Another way to work this out is with ratio

1:3 of 12 gifts
1+3 = 4
12 divided by 4 = 3
Each part is 3 gifts

Ava had $28.50 to spend at the farmer's market. After buying 3 pumpkins Ava, has $12 left. Which equation could you use to find

Alona [7]

Answer:

Step-by-step explanation:

Ava had $28.50 to spend at the farmer's market. She bought three pumpkins from the $28.50 that she had to spend.

After buying the three pumpkins, she had $12 left. This means that the amount that she spent on the pumpkin would be the total amount she had to spend - the amount she had left. This becomes

28.50 -12 = $16.5

This means that the cost pet pumpkin would be total amount that she spent on pumpkin / the number of pumpkin that she bought. It becomes

The equation that will be used to find the price of pumpkin,P would be

P = cost of n pumpkins /number of pumpkins

Where n is the number of pumpkins

In this case

Price of one pumpkin, p = cost of 3 pumpkins / 3 pumpkins

P = 16.5/3 = $5.5

Ellen said she spent half her money for lunch and half of what was left for a movie. She now has $1.20. How much did she spend f

goldenfox [79]

Answer: She spend $1.20 for lunch.

Step-by-step explanation:

Let the total amount be 'x'.

Half of her money spend for lunch be $\dfrac{x}{2}$

Half of her money left for a movie be $\dfrac{x}{2}$

Amount she has now = $1.20

So, According to question, it becomes ,

$\dfrac{x}{2}=1.20\\\\x=1.20\times 2\\\\x=\$2.40$

Hence, Amount she spend for lunch is $\dfrac{x}{2}=\dfrac{2.40}{2}=\$1.20$

Therefore, she spend $1.20 for lunch.

Mr. Barth is painting an arrow on the school parking lot. He draws the edges between the following points on the coordinate plan

andreyandreev [35.5K]

Answer:

70 square units

Step-by-step explanation:

I have plotted the points on the coordinate system and connected roughly using a red line. Image is attached.

The arrow created, consists of a TRIANGLE and a RECTANGLE. The area of the arrow would be:

Area of Arrow = Area of Triangle + Area of Rectangle

Area of Triangle = 0.5 * base * height

Base is 12 units

Height is 7 units, so

Area of Triangle = 0.5 * 12 * 7 = 42

Now,

Area of Rectangle = length * height

Length is 7

Height is 4

Area of Rectangle = 7 * 4 = 28

Area of Arrow = 42 + 28 = 70 square units
