45 is 26% of what number?

1 answer:

7 0

45 is 26% of 173.076

Change the percentage into a decimal by dividing the percentage over 100:
$\frac{26}{100} = 0.26$

Divide 45 by the decimal (0.26):
$45 \div 0.26 = 173.076$

1. The perimeter of the equilateral triangle below is 75. Solve for the value

Firdavs [7]

Answer:

Step-by-step explanation:

Given,

Perimeter of a triangle = 75

One side of the triangle = 5x

Therefore, 

By the problem, 

5x + 5x + 5x = 75

=> 15x = 75

=> x = 75/15

=> x = 5 (Ans)

Anna went to the grocery store. She bought 3 oranges and 6 apples. She paid $4.50. Maria went to the same store and bought 2 ora

klemol [59]

Answer: The apple costs 0.45

Step-by-step explanation: Oranges will be x in our equations and Apples will be y.

Anna's equation is: 3x + 6y = 4.5 (1)

Maria's equation is: 2x + 2y = 2.1 (2)

As we need to find y, we need to cancel x, this way, we multiply equation (1) by 2 and equation (2) by 3.

3x + 6y = 4.5 (x2)

2x + 2y = 2.1 (x3)

__________________

6x + 12y = 9

6x + 6y = 6.3

__________________

Now, we subtract them

6x + 12y = 9

-6x - 6y = -6.3

________________

6y = 2.7 → y = 2.7/6 → y = 0.45

Kyle is making a frame for a rectangular piece of art. The length of the frame is 3 times the width, as shown below. If Kyle use

satela [25.4K]

Answer:

———————

6.75 feet |

———————

Step-by-step explanation:

Let the width be x. If the width is x, the the length has to be 3x because in the question it says that the length is 3 times the width.

Since this is a rectangle, the opposite side has the same measure, like in the attachment below.

To find the perimeter, you would add up all the sides.

3x+3x+x+x

=6x+2x

=8x

It is also given in the question that he uses 18 feet. Which means that the perimeter is 18 feet. But you figured out that 8x is ALSO the perimeter. This means that you can say: 8x=18.

Solve for x, 18/8=9/4=2.25.

You want the length, which is 3x. So 3(2.25) is your answer.

3(2.25) = 6.75

Someone could help me out to find the answer thanks

Luden [163]

Answer:

h(x) = 11/(x -4)

Step-by-step explanation:

The domain of m(x) is restricted to x≠1. That means the domain of m(n(x)) must be restricted so that n(x)≠1, or x≠4.

The only offered choice with a domain restriction x≠4 is the 3rd choice:

h(x) = 11/(x -4)
