The school store sells pencils for $0.30 each, hats for $14.50 each, and binders for $3.20 each. Elena would like to buy 3 pencils, a hat, and 2 binders. She estimated that the cost will be less than $20.

1. Do you agree with her estimate? Explain your reasoning.

2. Estimate the number of pencils could she buy with $5. Explain or show your reasoning

Answers

1. No I do not agree with her estimate, because after adding up all of the cost of the things she wants to purchase, the cost will be over 20 dollars.

Answers

Answer:

1. C) 4 ft

2. B) 3 yds

3. C) 15840 ft

4. D) 128 oz

5. A) 105 oz

Step-by-step explanation:

For No. 1, to find how many feet, you can divide the number of inches by how many inches in a foot, or 12:

48/12 = 4 ft

For No. 2, to find how many yards, you would do the same. This time, there's 3 ft in a yard. You can also develop strategies for solving these. A ratio is a good way to visually see the problem:

3 ft      9 ft

-----  =  -----

1 yd     ? yd

Cross multiply:

3 · ? = 9

? = 3

For No. 3, to find how many feet in 3 miles, first recall how many feet in 1 mile. That's 5280 ft.

We want 3 of those, so you would multiply it:

5280 · 3 = 5280 + 5280 + 5280

               = 10560 + 5280

               = 15840

For No. 4, you can use a ratio again:

16 oz       ? oz

-------- =  --------

 1 lb        8 lb

Cross multiply:

16 (8) = ?

128 = ?

For No. 5, you can use the same ratio as No. 4:

16 oz       ? oz

-------- =  --------

 1 lb        6.5 lb

Cross multiply:

16 (6 1/2) = ?

(16 · 6) + (16 · 1/2) = ?

96 + 8 = ?

104 = ?

How many 1/2's are in 2 and 1/2?

Answers

Answer:

5

Step-by-step explanation:

there are 2 halves in one whole. Knowing that we will multiply, 2x2. That is 4, and then we will add the other half to our amount of halves to see the answer.

the answer is 5

This is because if you divide 2 and 1/2 by 1/2 you would get 5. So if you add 1/2 + 1/2 + 1/2+ 1/2+1/2 you would get 2 and a 1/2. If you count all the half’s you added there is 5.

Answer:

3.60

Step-by-step explanation:

took the test

Answer:

Area of the parallelogram is 3.69 ft²

Step-by-step Explanation:

We have,

A parallelogram in shape of a poster.And we need to find the area of parallelogram.

For solving,

The parallelogram is divided in 3 parts. 2 triangles and one rectangle.We will find all of there areas separately and then will add it up to have the final area of parallelogram.

★Area of triangles:

= ½ × base × height

= ½ × 0.5 × 1.5

= 0.5 × 0.75

= 0.375 ft²

Since there are to triangles of same size,

= 2 × 0.375

= 0.75 ft²

★Area of rectangle:

= Length × breadth

= 1.9 × 1.5

= 2.85 ft²

Final area of parallelogram:

= Area of both triangles + area of rectangle

= 0.75 + 2.85

= 3.60 ft²
