Greatest common factor of 28 and 42

Answers

Answer:

Step-by-step explanation:

To calculate the greatest common factor (GCF) of 28 and 42, we need to factor each number (factors of 28 = 1, 2, 4, 7, 14, 28; factors of 42 = 1, 2, 3, 6, 7, 14, 21, 42) and choose the greatest factor that exactly divides both 28 and 42, i.e., 14.

To write 0.64 as a __,multiply it by 100

Answers

If you multiply by 100 you will get the percentage

A(n) _____ in the money supply will cause interest rates to decrease, which, in turn, causes spending to _____. A.decrease; decrease
B.increase; increase
C.decrease; increase
D.increase; decrease

Answers

I think the correct answer from the choices listed above is option B. An increase in the money supply will cause interest rates to decrease, which, in turn, causes spending to increase. Decrease of interest rate means money is cheap which will result to more spending.

Answer:

increase; increase

Step-by-step explanation:

What is the percentage of 199.50 out of 286?

Answers

286 = 100 %
199.5 = x

In order to find x we need to cross multiply 286*x=199.5*100
286x=19950 / 286
x=69.8 (%)

What is the length of RS

What is the length of UV

Answers

Answer:

The length of RS is 22

The length of UV is 22

Step-by-step explanation:

6x-8. ---------- equation (i)

4x+2 ------------ equation (ii)

Now,

equating equation i and ii, we get

6x-8 = 4x+2

or, 6x-4x = 2+8

or, 2x = 10

or, x = 10/2

.°. x = 5

Then,

length of RS = 6x-8

= 6×5-8

= 30-8

= 22

Again

length of UV = 4x+2

= 4×5+2

= 20+2

= 22

Final answer:

The value of x is 5. The length of both RS and UV is 22.

Explanation:

In mathematics, when two lines or segments are said to be equal, it means you can set your two given equations equal to each other. In this case, you can equate RS to UV, which would give you the equation 6x - 8 = 4x + 2. To solve for x, you would start by moving the 4x from the right side of the equation over to the left by subtraction to get 2x - 8 = 2. Next, to isolate x, you would move the 8 over to the right side of the equation using addition, so the equation becomes 2x = 10. Finally, divide each side by 2 to get x = 5. To find the lengths of RS and UV, substitute x = 5 into the original equations, yielding RS = 6*5 - 8 = 22 and UV = 4*5 + 2 = 22.
