Hello!

You have to find \frac{4}{5} of 25

\frac{4}{5} =  \frac{x}{25}

Cross multiply

25 × 4 = 100

100 ÷ 5 = 20

The goalie made <u>20 blocks</u>

We can use a ratio expression to find the answer to this problem.

Set up the ratio.
4/5 = x/25
Multiply both sides by 25.
100/5 = x
Divide by 5.
20 = x
This means out of 25 times the ball is kicked toward the goal, the goalie will block it 20 times.

joanne cannot decide which of two washing machines to buy. The selling price of each is ​$660. The first is marked down by ​40%.
Alexxx [7]

Answer: The first machine would cost $420

and the second machine would cost $432

you should buy the first machine

Step-by-step explanation:If you get a 30% discount, then you are paying 70% of the selling price.

Machine 1:  600(.70) = 420

Machine 2:  A 10% discount means you pay 90%

600(.90) = 540   But now you get a 20% discount on that amount, which means you would pay 80%

So, 540(.80) = 432

Tiana replaced one Third of the buttons on her coat . If she replaced a total of 3 buttons,how many buttons are on tianas coat i
kompoz [17]

I believe the answer is 9, because 1/3 is .33 so 33%. so 33% is equal to 3 buttons and add another 66% which would be another 6 buttons would add up to 99% in all. after that I don't think they would add a quarter of a button.

Question number 3 pls
marissa [1.9K]
Factoring f(x) would give a factor (x-1-2i), so you can divide f(x) by this, leaving (x-3)(x+4)(x-1+2i), so the other roots are:

x=3
x=-4
x=1-2i

Answer:

  17.74

Step-by-step explanation:

The fraction is easily converted to one with a denominator of 100 (a power of 10):

Then the number of interest is ...

  17 37/50 = 17 74/100 = 17.74
