1 answer:

4 0

Dad = d
Carolyn = 1/2d
1/2d + d = 75
d = 50

1/2(50) + 50 = 75
25 + 50 = 75
75 = 75

Carolyn = 25 years
Caleb = 50 years

To make sure that a given parallelogram is a rectangle, at least hon many of

zmey [24]

Answer:

D. One

Step-by-step explanation:

A parallelogram will have two sets of equal sides. Since we have that fact, all we need to know are the angles.

A quadrilateral will have a total of 360° in its angles. If only one angle is equal to 90°, then we can do the math to figure out that all the others must be 90° as well. A rectangle is a parallelogram with the opposite sides being parallel and all the angles being 90°. This then answers the question.

"The Math"

-> Keep in mind there will be four angles

-> Once we subtract the first angle of 90°, we will have three angles left. Hence why we divide by 3.

360° - 90° = 270°

270° / 3 = 90° ✓

I’m stumped, can anyone please help me understand this

Answer:

B. Store T sells apples at the lowest rate

Step-by-step explanation:

Store R sells apples at $1.20 per pound.

Store S sells 4 pounds of apples at $5.00.

Store T sells 3 pounds of apples at $3.48.

To find the answer, you have to find the unit price for both Store S and Store T.

For Store S: 4 pounds = $5. Divide the cost by the pounds. This will give us $1.25 per pound.

For Store T: 3 pounds = $3.48. Same thing as Store S, divide the cost by the number of pounds. This will give us 1.16 per pound.

Now, we know the unit prices for each store. It's time to answer the question.

A. Store R sells apples at the lowest rate.

This is incorrect because the store that sells the apples at the lowest rate is Store T.

B. Store T sells the apples at the lowest rate.

This answer is correct, but I'll also take a look at the other two

C. Store S charges a lower rate for apples than Store T.

Again, this is incorrect because Store T sells apples at the lowest rate.

D. Store T charges the same rate for apples as Store R.

Nope, Store T sells the apples at a lower rate than Store R.

This means your answer will be B. Store T sells apples at the lowest rate.
