FIRST TO HELP ME WILL GET Brainleyist!!! Find the perimeter - 1

Answers

Answer 1
Answer:

Answer:

C. 31.8ft

Step-by-step explanation:

Perimeter of a parallelogram is calculated by this formula P = 2(a+b) (b: base, a: side)

The base given here is 10.8 ft and side is 5.1 ft

2 × (5.1+10.8) = 31.8 ft
Answer 2
Answer:

Answer:

B) 24.84.

Step-by-step explanation:

Its hard to explain but ===>

First do Pythagorean theorem with 2.3 and 5.1.

You will need to do two thing with that answer.

First subtract it from the 10.8.  That will be used for later.

Also, multiply it by 2.3 that is for the triangles that are on the sides.

Next you will want to take the number you set aside and multiply it by 2.3.

Finally add and you will have your answer.

Mason is going to have a lemonade stand. His Aunt buys him 10 lbs. of Lemons. if he sells each cup for a quarter,how many cups does he need to sell to pay her back?The Price of 1 lb. of Lemons is $0.89.

I have already did 0.89 x 10 which gives me 8.90.

Please Help

Answers

8.90 divided by 0.25= 35.6 (round up to 36 because you cant sell .6 cups of lemonade)

he would have to sell 36 cups of lemonade to pay his aunt back

after he sells 36 cups and pays his aunt back the $8.90 he will have $0.10 left to keep for himself
Okay, so first we do:

10 lbs × $0.89 = 8.90 (Which you did already)

Then we see how many cups he needs to sell, in order to get to $8.90.

.25 × 36 = $9

So that would be the approximate answer. 

The exact answer would be .25 × 35.6 = $8.9 or $8.90

The ratio of boys to girls of a class is 3 to 4. If there are 42 students, how many of them are boys? Show your work.

Answers

Answer:

There would be 18 boys.

Step-by-step explanation:

If the ratio of boys to girls is 3:4 that means in a classroom of 7 people there would be 3 boys and 4 girls. So all you do is multiply 3 boys by 6 (18) and 4 girls by 6 (24) cuz 7*6=42 which means that there would be a total of 42 students with 18 boys and 24 girls.

jayson buys a car and pays by installments.each installmentsis $567 per month.after 48 month, jayson owes $1250. what was the total price of the vehicle ?

Answers

Let

T--------> the total price of the vehicle

x--------> amount paid

y--------> amount owed

we know that

the total cost of the vehicle is equal to the amount paid plus the amount owed

so

T=x+y

Find the amount paid

x=567*48\n x=27,216\ dollars

Find the amount owed

y=1,250\ dollars

Find the total cost of the vehicle

T=x+y\n T=27,216+1,250\n T=28,466\ dollars

therefore

the answer is

the total price of the vehicle is 28,466\ dollars

The total price of the vehicle is 28,466

  • Each installment monthly = $567
  • Amount owes by Jayson after 48 months = $1250

Further Explanation

To determine the total price of the vehicle, we can solve this question using the area model (please refer to the attachment below)

Firstly, let’s use the area model method to calculate the total price of the vehicle.

Therefore, we have:

567 x 48

= (500 + 60 + 7) x (40 + 8)

= (500 x 40) + (500 x 8) + (60 x 40) + (60 x 8) + (7 x 40) + (7 x 8)

= 20000 + 4000 + 2400 + 480 + 280 + 56

= 27216.

Recall, Jaycee still owes $1250 after 48 months; therefore we can derive the total price of the vehicle by adding the total money for the whole 48 months and the amount Jayson owes.

Therefore we have:

27216 + 1250

= 28466

Thus, the total price of the vehicle is $28,466

The area model refers to a rectangular diagram used in solving multiplication and division problems in mathematics.
