Find the surface area of the prism. 7 mm 4 mm 5 mm

Mathematics
1 answer:
dolphi86 [110]3 years ago
7 0

Answer:

Since there are 2 sides, a front & back, and a top & bottom, you must find the surface area of each of those 3 surfaces and multiply by 2.

Step-by-step explanation:

The formula would be:

Top & Bottom - 5 × 4 (multiply by 2 for top AND bottom)

Front & Back - 5 × 7 (multiply by 2 for front AND back)

Sides - 4 × 7 (multiply by 2 for BOTH sides)

___________________________________________________

Once you find the 3 surface areas, add the areas all together for the total. (I did not show the answer because that is for you to do on your own.)

Ex. Top & Bottom + Front & Back + Sides

What is -4/3 on this? Say all that apply (5 stars and brainliest for best answer)
Aleks04 [339]

Answer:

Rational Numbers

Step-by-step explanation:

- An integer in its most simplified form cannot be a decimal nor a fraction, meaning -4/3 nor -0.75 would work.

- A whole number is a number that is either positive or negative but cannot be a decimal in simplified form. -4/3 is -1.333.... which is less than one and negative, meaning it cannot be a whole number due to it obviously being a decimal.

- -4/3  is not a natural number as it is both a decimal and negative.

- -4/3 is not irrational because it repeats when in decimal form.

- -4/3 is rational as in decimal form it repeats and to give more information, rational numbers can be both positive and negative numbers. The 3 that repeats in the decimal form of -4/3 works as a rational number due to this.

Therefore, it would apply to the first square.

Thanks!

A factory uses 1/8 of a barrel of raisins in each batch of granola bars. Yesterday, the factory used 3/4 of a barrel of raisins.
dimaraw [331]

Answer: 6

Step-by-step explanation:

From the question, we are informed that a factory uses 1/8 of a barrel of raisins in each batch of granola bars and that the factory used 3/4 of a barrel of raisins yesterday.

To calculate the number of batches of granola bars that the factory made yesterday, we divide 3/4 by 1/8. This will be:

= 3/4 ÷ 1/8

= 3/4 × 8/1

= 24/4

= 6

The company made 6 batches of granola bars
