Ella wants to make a fruit salad for herself and 5 friends.

She has 5 cups of grapes, 3 pints of strawberries, and 1 quart of watermelon pieces.

1. How many cups of fruit salad does Ella have?

2. If she wants to share the fruit salad between herself and 5 friends, how much fruit salad will each person get?
Answer both to get brainlest. Also please explain.

Answers

1. I believe she would have 15 cups of fruit salad because it’s 5 cups of grapes, 6 cups strawberries(1 pint = 2 cups which means 6 cups of strawberries) and 4 cups of watermelon (1 pint = 4 cups
2. Since there are 15 cups of fruit salad you would need to divide 15 by the number of friends which would make it 2.5 cups of fruit salad per person
1.) 15 cups
2.) 3 cups per person

Nicole is half as old as Donald. The sum of their ages is 72.

How old is Nicole, in years?

Answers

Your gonna divide 72 by 2 so therefore you get 36
So that equals to Nicole’s age

Answer:

24 years

Step-by-step explanation:

let Donald's age be x

then Nicole's age would be 1/2 * x = x/2

now, x + x/2 = 72

3x/2 = 72

3x = 72*2

x = 144/3 = 48

Donald's age is 48, so Nicole's age is 1/2 * 48 = 24 years.

The cost for the number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. How many shirts were purchased?

Answers

Answer:

6x + 4 - 1/100 = 77.5

Step-by-step explanation:

Inc shipping all shirts 77.49

Shirt individual cost = 12.25

We find the division first = 77.49-3.99 = 73.5  = 73 1/2

Then we divide 73.5 / 12.25 = 6

Then we have our equation

6x + 4 - 1/100 = 77.5

1/9 of the shirts sold at Peter’s shop are striped. 5/8 of the remainder are printed. The rest of the shirt are plain colored shirts. If Peter’s shop has 81 plain colored shirts, how many more printed shirts than plain colored shirts does the shop have?\

Thanks
Spectrier

Answers

Answer:

54 more printed than plain shirts.

Step-by-step explanation:

Alright, so... if 1/9 of the shirts are striped and 5/8 of the remaining shirts are printed then 3/8 of the remaining shirts are plain.  if 81=3/8 of the remaining shirts then 1/8 of the remaining shirts is 27 shirts.  27x5=135 meaning  135 of the remaning shirts are printed.  If 1/8 of the remaining shirts is 27, there are 216 total remaining shirts.  This also means that 216 is 8/9 of all of the shirts.  Since 27 is 1/8 of the remaining shirts, 216+27=the total amount of shirts.  216+27=243.  243/9=27 meaning that 1/9 of the shirts is 27 (which also means I did that math for no reason, it's 2:00 am, my brain can't funtion rn XD).  135 printed shirts-81 plain shirts=54.  There are 54 more printed shirts than plain shirts.  Sorry if I am wrong, hope it helps.  Have a wonderful day!

So Nelly gets £8 an hour for the first 15 hours, so you have to find the product of 8 and 15 which is £120. Then she gets an extra £10 for every extra hour, so we have tl subtract 15 hours from how many total she worked. To do that, we first have to add all of the hours together which would be 22 hours. Then we have to subtract the 15 which is 7 hours. However, the 5 hours on Saturday are going to pay double so we will calculate that afterwards. so 7 minus 5 is 2. Nelly gets paid £8 pounds for every hour so she gets £16 for 2 hours. Now, since are doubling £8 we get £16. So Nelly gets paid £16 an hour for the hours she worked on Saturday. 5 times 16 is £80. Now we add it all together. £120 + £16 + £80 = £216

Hope this helps :)

Do the calculation below

6(18 + 14)

Answers

Answer:

Explained below...

Step-by-step explanation:

First, recognize the acronym PEMDAS, which stands for:

P - Parenthesis

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

So, as there are parenthesis, that will be your first step in the expression.

6(18 + 14) --> 6(32)

Now, you will find the next step in PEMDAS, which would be multiplication.

6 * 32 = 192.

So, your answer for the equation is 192.

Hope this helps! :)

Answer:

6(18 + 14) = 192

Help Please, There are 5 rectangular flower gardens each measuring 16 feet by 13 feet in a rectangular city park measuring 90 feet by 140 feet. How many square feet of the park is not used for flower gardens?

Answers

Answer:

11560 ft squared

Step-by-step explanation:

16 x 13 = 208

208 x 5 = 1040 ft2

1040 ft 2 is how much space used

90 x 140 = 12600 ft2

12600 ft2 is all of the space

12600 - 1040 = 11560 ft squared

the answer is 11560 feet squared
