grapes are sold for $3.20 per bag. if you have $12, how many bags of grapes can you buy?

Answers

Answer:

you can buy 4 bags of grapes with $12.

Step-by-step explanation:

Hope this helps :)

Answer:

Step-by-step explanation:

Since we know that one bag of grapes = $3.20, we can divide $12 by $3.20 to get how many bags of grapes you can buy.

12/3.2=3.75.

In the exact amount, you can buy 3.75 bags of grapes. Now you can't buy .75 of a bag. Rounding it, you would have approximiatly bought 4 bags. Reality, you would have bought 3 bags.

The area of a parallelogram is the same as the area of a square. The base of the parallelogram is twice the length of its height. The side of the square is 2 less than the height of the parallelogram

Area of a parallelogram: a = base • height

Area of a square: a = (side)2

1. variable h = parallelogram height

2. square area + parallelogram area

3. equation: (h – 2)2 + (2h • h)

two angles in a triangle have measures of 62 degrees and 15 degrees. What is the measure of the third angle.

A.92 degrees

B.47 degrees

C.77 degrees

D.103 degrees

Answers

Answer:

the answer is 103

Step-by-step explanation:62°+15°=77° degrees

Then it is 180° - 77° degrees

180°-77°=103°

The measure of the third angle of a given triangle is 103°.

Given that the measure of two angles is 62° and 15°.

We need to find the measure of the third angle.

What is the angle sum property of a triangle?

The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°.

Let the measure of the third angle be x.

Now,  62°+15°+x=180°

⇒x=180°-77°

⇒x=103°

Therefore, the measure of the third angle is 103°.
