The correct answers are:

90°, 180° and 270°

Explanation:

Squares have rotational symmetry at 90°. This can be found by dividing the number of degrees in a circle, 360, by the number of sides, 4:

360/4 = 90

This means that at all multiples of 90, the square will rotate onto itself. This means that 90, 180 and 270 are all correct.

Answer:

A.)351 cubic inches

Step-by-step explanation:

The computation of the volume of the prism is shown below:

As we know that

Volume of the prism is

= Base × height

= 27 square inches × 13

= 351 cubic inches

hence, the first option is correct

And, the rest of the options are wrong

Someone please help me on this math problem!

Galina-37 [17]

Look at the picture.

Therefore we have the equation:

10y - 29 = 7y + 19 add 29 to both sides

10y = 7y + 48 subtract 7y from both sides

3y = 48 divide both sides by 3

y = 16

3x + 7 = 5x - 21 subtract 7 from both sides

3x = 5x = -28 subtract 5x from both sides

-2x = -28 divide both sides by (-2)

x = 14

Because of this, the pair of opposite numbers are 3 and 8 if you want the pair that equal 11.

Someone please help me I only have until January 18th to turn this in. Question: Mr Lopez picks up 2 pallets of dog food to deli

miv72 [106K]

Answer:

Mr. Lopez delivers 1.5 tons of dog food to the animal shelter.

Step-by-step explanation:

Mr Lopez picks up 2 pallets of dog food to deliver to the animal shelter. Each pallet contains 40 bags of dog food, and the dog food weighs 37 1/2 pounds pet bag.

The weight of 1 bag of dog food = $37\frac{1}{2}\text{ pounds }$

The weight of 40 bags of dog food = $40 \times 37\frac{1}{2} =1500 \text{ pounds }$

Each pallet weighs = 1500 pounds

2 pallets weighs = 1500×2=3000 pounds.

We know that 2000 pounds = 1 ton

$\frac{3000}{2000} \text{ pounds}=1.5 \text{ tons}$

Hence, Mr. Lopez delivers 1.5 tons of dog food to the animal shelter.
