Find 72% of 50(REEEEEE)​

Mathematics
1 answer:
Snowcat [4.5K]3 years ago
8 0

Answer:

The answer is 37.44

Step-by-step explanation:

Step 1: Divide 52 by 100

In this case, the number that we are "comparing" to 100 is 52, so we must first normalize the number by dividing it by 100. The operation we have to solve is this:

52

100

=

52

÷

100

=

0.52

Step 2: Multiply 0.52 by 72 to get the solution

Now that we have our normalized number, 0.52, we just have to multiply it by 72 to get our final answer. The forumla for this is obviously quite simple:

0.52

×

72

=

37.44

What value does each equation need to be multiplied by in order to eliminate the y terms equation 1 6x-5y=-4 equation 2 4x+2y=28
Alex777 [14]
In order to eliminate the y term, you need to find what y is equal to in the equation.
1. 6x-5y=-4
-5y=-4-6x
Y=6/5x+4/5
You then sub in 6/5x+4/5 in for y in the equation
2. 4x+2y=28
2y=-4x+28
Y=-2x+14
Hope this helps!

The ABC company's brand has a market share of 30%. Suppose that in a survey, 800 consumers of the product are asked which brand
Anna007 [38]

ABC market share = 30%

number of customers surveyed = 800

probability that more than 32% prefers ABC

p ( x ≥ 256 )

= 1 - ( 256/800 )

Dmitriy789 [7]
Just add the two equations together.
2b = 18
b = 18/2
b = 9

9 = k + 10
9 - 10 = k

What is 5% of 220? Show work please
luda_lava [24]
It is easier (for me anyway) to find 10% then work around that.
Following that path would mean that, by making a table:

100% = 220
10% = 22
5% (Which is half the 10) = 11
