Aubrey claims that if the dimensions of the parallelogram shown are doubled, then the area of the larger parallelogram will be 4 times more than the original. Which statement about her claim is completely true?
A parallelogram with a base of 6 inches and height of 3 inches. A side has a length of 5 inches.

Aubrey is correct because the area of the new parallelogram is 12 (6) = 72 square inches. The original area is 18 square inches. Since 4 (18) = 72, the new parallelogram has 4 times the area of the original.

Aubrey is correct because the area of the new parallelogram is 10 (7) = 70 square inches. The original area is 18 square inches. Since 4 (18) = 72, it is about 4 times larger than the original.

Aubrey is incorrect because if one doubles each dimension, then the area will automatically be doubled as well. The original area is 18 square inches so the new parallelogram will have an area of 2 (18) = 36, or two times more than the original.

Aubrey is incorrect because if one doubles each dimension, then the area will automatically be doubled as well. The original area is 30 square inches so the new parallelogram will have an area of 2 (30) = 60, or 2 times more than the original.

Answer 2

Answer:

The last one you listed is correct

Step-by-step explanation:

The area can be shown as length times width or length times the base of a shape. 6 times 5 would give you an original area of 30 and the last one listed as an answer is the only one that even says the original area is 30.

David has pears and apricots in a ratio of 24:20. How many pears does he have if he has 5 apricots?

On the double number line below, fill in the given values, then use multiplication or division to find the missing value.

Answers

Answer:

The answer is 6 pears.

The answer is 6 pears.

First turn the ratio into a fraction.
The fraction would be 24/20

Next find the greatest common factor.

You do this by finding the greatest common factor which would be 4.
Four is the GCF because it is the highest number that you can divide both 24 and 20 by.

Since the question is in the order of pears then apricots you divide 24 by 4 to get the number of pears.

Your final answer is 6.

Find the Surface Area of the Pyramid. Round to the NEAREST TENTH.

Answers

Answer:

Step-by-step explanation:

The side triangles are: 352.35

Middle triangle is: 113.4

352.35 + 113.4 = 465.75

Answer:

465.75 or 465.8 rounded to the nearest tenth

Step-by-step explanation:

You would multiply 16.2 and 14.5 and divide by 2 to get 117.45. You then multiply by 3 for the 3 sides to get 352.35. Lastly, to find the area of the base you would need to multiply 16.2 and 14 and divide it by two to get 113.4. Add it with the 3 sides and you get 465.75.

What is the total surface area of the triangular prism? Round to the nearest hundredth if necessary.

Answers

Answer:

Step-by-step explanation:

There are 5 surfaces:

2 surfaces as triangle, each with area = 5 x 4.3 /2 = 10.75sqft

3 suraces as rectangle, each with area = 10 x 5 = 50sqft

Total surface area = 50 x 3 + 10.75 x 2 = 150 + 21.5 = 171.5 sqft

A regular-size box of crackers measures 2 inches by 9 inches by 14 inches. The manufacturer also sells a snack-size box that has a volume that is 1/4 of the volume of the regular-size box. What is the volume of the snack-size box

Answers

Answer:

Step-by-step explanation:

2 x 9 x 14 = 252, 1/4 of 252 is 63

Answer:

63 in³

Step-by-step explanation:

Volume of regular box = width × length × height

= 9 × 14 × 2

= 252 in³

If the snack box is 1/4 of the volume of the regular-size box, to find the volume of the snack box, multiply the volume of the regular-size box by 1/4:

Volume of snack box = Volume of regular box × 1/4

= 252 × 1/4

= 252 ÷ 4

= 63 in³

Answer: 84 in

Step-by-step explanation:
The area of a triangle would be 1/2 bh so the first step would be to find the area of the triangle. So, you would need to multiply 6*6 and then divide it by 1/2. Then you would need to find the area of the rectangle, for this you would need to multiply the length times the width which would be 6*11 then you just add both of the areas up. which would be 84.

The answer is 84 in

Step 1: area of rectangle
A = a x b
A = 11 x 6
A = 66 in

Step 2: area of triangle
A = 1/2 x a x b
A = 1/2 x 6 x 6
A = 18 in

Step 3: total area
A = 66 + 18
A = 84 in

Factor the expression using the GCF.

(This is not the same as my last question) Find the value of X

A. 25
B. 7
C.11
D.18

Answers

Answer:
B. 7

Step-by-Step-Explanation:
This is a right angle, a right angle is equal to 90° since it is 1/4 of 360
(360 is all the way around)

Our equation here is;
5x° + 55° = 90°
(we do inverse operation, inverse of addition is subtraction.)
Subtract 55° from both sides, 55 - 55 cancels out (0)
90° - 55° = 35°

Now our equation is;
5x° = 35°
(to find x we need to find out what 1x equals so we divide 35° by 5°)
(35 / 5 = 7)
x = 7

To make sure we plug in it into our original equation (5x° + 55° = 90°)
5(7)° + 55° = 90°
35° + 55° = 90°
(35 + 55 = 90 so this is correct)

x = 7

the value of c is B. 7
