A soccer team played 32 games. If they won 25% of them, how many games did they win?

Answers

X/32= 25/100
100x, 800
800 divided by 100= 8
X = 8 games

25% is the same as 1/4.
1/4 is the same as ÷ 4
32 ÷ 4 =
16 ÷ 2 =
8

If a soccer team won 25% of their 32 games, they won 8 of them.

Which of the following prefixes is best for measuring large quantities like the mass of a person?milli
kilo
deci
deca

Answers

Kilo, for kilogram is the best to use for easuring the mass of a person. 1 Kilogram (Kg) = 1000 grams. For example, I have 60 kilograms (132.27 pounds).

Mili is used for very small quantities (Mili = 1/1000 grams). Deci = 1/10 grams and deca 10 kilograms = 10.000 grams. Good luck !

The metric unit for weight is kilo.

PLZ HELP ME! I WILL MAKE YOU BRAINLIEST! Xian and his cousin Kai both collect stamps. Xian has 60 stamps, and Kai has 76 stamps. The boys recently joined different stamp-collecting clubs. Xian's club will send him 16 new stamps per month. Kai's club will send him 12 new stamps per month. After how many months will Xian and Kai have the same number of stamps? How many stamps will each have? THANKS!

Answers

Answer: After 4 months they will have the same number of Stamps

Xian and Kai will have 124 stamps each one.

Step-by-step explanation:

60+16x = 76+12x (Subtract 12 from both sides)

-12 -12

60+4x = 76 (Subtract 60 from both sides)

-60 -60

4x/4x = 16/4x (Divide 16 by 4)

X = 4

Which is more 0.02 or 0.1 ?

Answers

0.1 is the same as 0.10. If you forget the decimal it is 02 and 10 which is the same as 2 and 10. 10 is bigger than 2 so the answer is 0.1

.1 because if you change .1 to = .02 it is .10 and .10 is bigger than .2

What+8,477.6=10,248 what+0.07=0.1

Answers

x+8477.6=10248
-8477.6 -8477.6 1770.4+8477.6=10248
x=1770.4

x-0.07=0.1
+0.07 +0.07 0.17-0.07=0.1
x=0.17

Question one: x + 8477.6 = 10248

solve your equation step-by-step.

x+8477.6=10248

Subtract 8477.6 from both sides.

x+8477.6−8477.6=10248−8477.6

x=1770.4

S0 1770.4 + 8477.6 = 10248

Question two: x + 0.07 = 0.1

solve your equation step-by-step.

x+0.07=0.1

Subtract 0.07 from both sides.

x+0.07−0.07=0.1−0.07

x=0.03

So 0.03 + 0.07 = 0.1

If 2b= -3, what is the value of 1 – 4b?

Answers

If we have the expression 2b = -3, then the value of the expression 1 - 4b is 4.

Step 1: Solving for 'b'

We are given the equation 2b = -3. To isolate 'b,' we need to get rid of the coefficient 2 attached to 'b'. To do that, we'll divide both sides of the equation by 2:

2b / 2 = -3 / 2

b = -3/2

Step 2: Substitute 'b' in the expression 1 - 4b

Now that we have the value of 'b' as -3/2, we can substitute it into the expression 1 - 4b:

1 - 4(-3/2)

Step 3: Simplify the expression

To simplify the expression, we'll perform the multiplication first:

1 + 6/2

Next, we add 1 and 6/2:

1 + 3 = 4
