what is the GCF of 45 and 60?

Answers

Answer:

The GCF of 45 and 60 is 15.

Step-by-step explanation:

First let us find the factors of 45 and 60.

[tex]\left[\begin{array}{ccc}&45&\\15&*&3\\5*3&&\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}&60&\\15&*&4\\5*3&&2*2\end{array}\right][/tex]

Based on this, you can tell that they both have the number 3 and the number 15 in their factors.

15 > 3

The GCF of 45 and 60 is 15.

What is the length of the shortest side if the perimeter of the rectangle is 56 inches?

Answers

Answer: Length of Shortest Side = 12 inches

Step-by-step explanation: Length of Shortest Side = L = 3x

Length of Longest Side = W = 5x-4

Condition:

2L+2W = Perimeter

2(3x)+2(5x-4) = 56

6x+10x-8 = 56

16x-8 = 56

Adding 8 to both sides

16x = 56+8

16x = 64

Dividing both sides by 14

=> x = 4

Now,

Length of the Shortest Side = L = 3(4) = 12 inches

Length of the Longest Side = W = 5(4)-4 = 16 inches

If the radius of a circle is cut in half, what is the scale factor needed to adjust the area of the original circle to the smaller circle?

Answers

When the radius is halved, your area will be divided by 4. If you think about it, radius is already half of the diameter so your area is already divided by 2, so if you cut the radius is half again, your area will be divided by 4.

Calculate the value of x

Answers

Answer:

x = 55

Step-by-step explanation:

x + (2x+15) = 180

3x + 15 = 180

3x = 165

x = 55

Answer:

55°

Step-by-step explanation:

since angles in a straight line add up to 180°

x+2x+15=180°

3x+15=180°

3x=180-15

3x=165

divide by 3 on both sides

x=55°

Isaac’s family took a cab to a concert. The bill came to a total of $43.50. The family wants to tip the driver at least 20%. Which tip amounts would be sufficient? Select all that apply.

$9
$10
$11

Answers

Answer:

The option d is the correct answer

to find a percentage of something we were taught this method

%% x
—— • ——
100 total price

you then want to multiply the total price by the percentage and then divide by 100

so in this case

20 x
—— • ——
100 $43.50

20•43.50=870

870/100= 8.7

so i believe 9,10,11 would all be correct.
