For answer #1. just divide both numbers by 8.
Let's see:
400=8r
400/8=8r/8
400/8 equals 50
So, answer #1 is 50.

For answer #2, count the number of times it shows 5, then write that number on the top, in the right-hand corner.(or use an arrow to show it's going up)
Let's see:
5×5×5×5×5=5 times it shows 5
So, 5∧5 would be the answer.

R=50 because 8×50=400 so that is what r would equal
The exponent would be 5 the fifth power, because since the number your using to multiply it by is 5 and you are multiplying is by 5 fives it would be 5 to the fifth power

The side lengths of a triangle are 5, 8, and 12. Is this a right triangle?
professor190 [17]

Answer:

A) No...

Step-by-step explanation:

We can check if this triangle is a right triangle by using the Pythagorean Theorem.

  • a² + b² = c²
  • where a and b are the legs of the right triangle, and c is the hypotenuse (longest side)

Using 5 for a, 8 for b, and 12 for c, let's see if this satisfies the equation:

  • 5² + 8² = 12²

Simplify.

  • 25 + 64 = 144
  • 89 = 144

We can see that 89 ≠ 144, so this leaves us with answer choices A and B. I think you meant to write < for the last + sign.

Seeing as the sum of the two lengths of the triangle is greater than the third side length, this creates a normal triangle. This cannot be the correct answer choice since this only satisfies the requirements for a triangle, but not a right triangle.

This leaves us with answer choice A.  52 + 32 ≠ 122 and 52 + 32 < 122. (I'm not sure why the squares of the side lengths are not used, but this should be the correct answer.)

A jacket costs $45. The sales tax on the jacket is 6%. Julia has $48.
liubo4ka [24]

Answer:

Julia has enough money to buy the jacket.

Step-by-step explanation:

6% of 45 is 0.06*45

With the sale tax jacket costs

45 + 0.06*45 = 47.7 or $ 47.70

$ 47.70 < $ 48

So, Julia has enough money to buy the jacket.
