If 2a+3<10 then which of these could be a value of a?
A. 6
B. 4
C. 2
D. 10

How would you find 28% of 612?
A. Take 0.28 multiplied by 612
B. Take 0.28 divided by 612
C. Take 0.0028 multiplied by 612
D. Take 0.028 divided by 612?

C. 2

A. Take 0.28 multiplied by 612

Step-by-step explanation:

We can make the first problem an easy comparison of numbers by simplifying the inequality 2a + 3 < 10:

2a + 3 < 10    (Subtract 3 from both sides)

2a < 7    (Divide both sides by 2)

a < 3.5

This means that a has to be less than 3.5, which means the answer is C. 2.

To find a percentage, we need to simply multiply the given number by said percent. In this case, we need to find what 28% of 612 is. We know that percentages can be written with a denominator of 100: , which can be simplified into a decimal as 0.28.

Now we just apply the property that we multiply the given number by said percent to get the value, which means that the answer is A. Take 0.28 multiplied by 612.

other answer is correct. i had used the radius of the radius somehow. a website:
