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?
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

Answer:
312.5 t⁴
Step-by-step explanation:
25*t⁻⁴ = (5²) / t⁴ (1)
5⁻³*10*t⁻⁸ = 5⁻³*2*5¹ / t⁸ (2)
(1)/(2): ((5²) / t⁴) / ((5⁻²*2) / t⁸) = 5⁴ * t⁴ / 2 = 625 t⁴ / 2 = 312.5 t⁴
Answer:

I need help.... Quickly!
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)

GivenR is the midpoint of SQ and PTTo proveΔPQR ≅ ΔTSRSolutionR is the midpoint of SQ
SR = 1/2SQ and RQ = 1/2SQ ⇒ SR ≅ RQR is the midpoint of PT
PR = 1/2PT and RT = 1/2PT ⇒ PR ≅ RTSQ and PT intersect at point R ⇒
∠PRQ ≅ ∠TRS as vertical anglesTriangles PQR and TSR have two sides and the included angle congruent, therefore:
ΔPQR ≅ ΔTSR,as per SAS congruence postulate

24 + 125 + 31 = 130
Your doctor told you to eat 25 25 grams of fiber each day. You had 4 4 grams of fiber for breakfast. What percent of the 25 25 grams of fiber have you eaten so far?
Answer: 16%

Grams of fiber recommended by doctor = 25 grams
Grams of fiber had for breakfast = 4
Percentage of gram ate = Grams had for breakfast / Grams recommended by doctor × 100
= 4/25 × 100
= 4 × 4
= 16%

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?
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.
