Maria's Grocery Store buys grapefruit at a cost

of 5 for a dollar. They sell them at a price of 5

for three dollars. How many must they sell in

order to make a profit of ten dollars?

Answers

Answer: 25 grapefruits

Step-by-step explanation:

They buy grapefruit at a price of 5 per dollar. This means that the price per grapefruit is:

= 1 / 5

= $0.20 per grapefruit.

They then sell at a price of 5 per $3. The selling price per grapefruit is:

= 3 / 5

= $0.60

The profit per grapefruit is:

= 0.60 - 0.20

= $0.40

In order to make a profit of $10, they should sell:

= 10 / 0.4

= 25 grapefruits

Angelica has a babysitting business. She babysat on Friday night and made $60
plus a 20% tip. How much was the tip? How much was the total?

Answers

Answer:

The tip was $12. The total was $72.

Step-by-step explanation:

First, we need to find how much the tip is. 20%=1/5 of the amount of money. If you divide 60 by 5, you get 12. This means that the tip was 12 dollars. If you add 60+12 you get 72 meaning that the total amount of money Angelica got was $72.

The tip was $12 so the total amount would be $72.

You take 60 and multiply it by .2 , then you will get the 20% tip.

Step-by-step explanation:

GivenR is the midpoint of SQ and PTTo proveΔPQR ≅ ΔTSRSolution

R is the midpoint of SQ

SR = 1/2SQ and RQ = 1/2SQ ⇒ SR ≅ RQ

R is the midpoint of PT

PR = 1/2PT and RT = 1/2PT ⇒ PR ≅ RT

SQ and PT intersect at point R ⇒

∠PRQ ≅ ∠TRS as vertical angles

Triangles PQR and TSR have two sides and the included angle congruent, therefore:

ΔPQR ≅ ΔTSR,

as per SAS congruence postulate

If two sides and the included angle in one triangle are congruent to two sides and the included angle in another triangle, then the two triangles are congruent

Answer:

Rectangle Y.

Step-by-step explanation:

Find the perimeter of both rectangles.

If you want to find rectangle X, the breadth of the rectangle but the length of it isn't the same since it has been shortened, and since it covers half of the card for length...

Length = 14 ÷ 2 = 7cm

Perimeter = 6cm + 6cm + 7cm + 7cm = 26cm (Rectangle X)

Now, let's find perimeter for rectangle Y.

The length for the rectangle is the same as it isn't shortened or anything else, but the breadth is different as it have been shortened, since it covers half of the card for breadth...

Breadth = 6 ÷ 2 = 3cm

Perimeter = 3cm + 3cm + 14cm + 14cm = 34cm

(Rectangle Y)

Explaination: Rectangle Y will have the longer perimeter, (add in the solution that I wrote for rectangle X and Y)
