Answers

Answer 1

Answer:

79.8 cm²

Explanation:

surface area of triangular prism: (a + b + c) × length + base × height

Here given:

a = 3 cm, b = 3 cm, c = 3 cm, length = 8 cm, base = 3 cm, height = 2.6 cm

Inserting the values:

(a + b + c) × length + base × height

(3 + 3 + 3) × 8 + 3 × 2.6

79.8 cm²

If a certain measurement of a polygon is 283 in2, it means:

A. the polygon's measurements are 283 inches by 283 inches.

B. the polygon's volume is 283 in?

C. 283 one-inch by one-inch squares will fit over its surface.

D. none of the above.

Answers

Answer A

In^2 this multiplies the number used by itself therefore in your case 283 x 283. You are using the measurement for inches.

Answer: C

Step-by-step explanation:

A says the polygon's measurements are 283 inches by 283 inches. Is it Correct? No. If we multiply these numbers we get 80,089 inches squared, which is not equal to our actual surface of 283 inches squared.

B says the polygon's volume is 283 inches cubed, which is not correct because it says that a certain measurement of a polygon is 283 inches squared, not cubed, which means we got a surface/area, not a volume.

C says that our 283 inches squared area could fit 283 one-inch by one-inch squares, which is correct because one-inch by one-inch is an one inch squared area, if we multiply this one-inch squared by the number 283, we get 283 inch squared area.

And D couldn't be because the answer is C.

how do i find the LCD? ( Lowest Common Denominator )

Answers

Answer:

First for example let's say

3 and 15

your going to doing what you do normally for gcf but then make an l and times it if that makes sense

Step-by-step explanation:

To find the Lowest Common Denominator, or LCD, you would start by listing the multiples of two numbers. From there, you would find the smallest integer of the two that are the same. That would be your lowest common denominator because it’s the lowest number that the two given denominators have in common. For example, let’s take the numbers 2 and 5:

Multiples of 2:

2, 4, 6, 8, 10, 12, 14, 16, 18, 20

Multiples of 5:

5, 10, 15, 20, 25, 30, 35, 40, 45, 50

The two numbers common in the multiples seen above are 10 and 20, because they are multiples of both 2 and 5. However, 10 is less than 20, which would render it to be the lowest common denominator. In cases like this, the lowest integer (the number closest to 0) will always be the LCD.

If you have any further questions, I am open for discussion. Have a nice day!

Answers

Answer:

C (√34)

Step-by-step explanation:

Pythagoras' theorem states that: a² + b² = c², where c is the hypotenuse and what we are trying to figure out.

So, 3² + 5² = c²

9 + 25 = 34 = c²

c = √34

Add 7 on both sides then multiply by 2 to isolate m, and you should get m=4, so the answer is

the last option.

Hope this helped :)

The last one because m/-2= 4/-2=-2-7 which would equal -9 cause negative and negative equals to negative
