Answer: 90

Step-by-step explanation:

The key word is "of." Anytime you see "of," multiply the two variables given.

For example, you have 30% × 300. <u>Recall that percentages are out of </u><u>100.</u> This mean that 30% is 30/100, or 0.30. Multiply 0.30 and 300 and you get 90.

42.5p=c

You get you get the number 42.5 since you know 10 people paid 425, you would divide 425 by 10 to know how much every person paid.

M is representing the amount of money each person paid

(M)10=425
M=425/10
M=42.50 <- since it’s about money

Each person paid $42.50


The cost for 15 people is $637.50.

42.5p=c
42.5(15)=637.5

Which is largest 3.3 times 10^5 or 3.1 times 10^5
erik [133]

Answer: 3.3 times 10^5 is bigger

Step-by-step explanation: 10^5= 10*10*10*10*10=100,000.

so 100,000 multiplied by 3.3 = 330,000

or 3.1 multiplied by 100,000 = 310,000 so it's obvious that 330,000 is bigger.

The measure of one of two complementary angles is 6 degrees less than one half the measure of the other. Find the measure of the
solmaris [256]
It's helpful to choose letters to represent the measures of these complementary angles.  Let x represent one and y the other.

What does "complementary angle" mean?  x + y = ??

Let x be the smaller angle.  First, we take "half the measure of the larger angle," or (y/2).  Then we subtract 6 degrees from this result (y/2).  The result is the xmaller angle, x.

Now you have two equations in x and y.  Solve for one of these angles, and then find the other.  Please show your work.
