Answer:
Boys: 75%
Girls: 25%
Step-by-step explanation:
Total: 28 Students: 100%
7 Girls in clas
28(total)-7 (girls)= 21 Boys in class
__________________
If we divide the amount boys OR girls ( depending on which gender) after the toal and move the decimal to the right twice after dividing) we will get our answer.
Formula:
(Amount of Boy or girls) = x
X/28
So since we are trying to get the percentages of boys, we will replace X with the amount of boys
21/28 = .75 ( then move the decimal to the right TWICE) = 75
Then you should get your percentages: 75% Also if your lookings for girls percentages, you basically subtract 75 ( boys percentages) with the total percentages ( 100) then you should get your answer for the girls: 25%
Answer:
wilma is 22.5 mph
fred is 25.5 mph
Step-by-step explanation:
Time:40 minutes, or 2/3 hours
Speed:
Fred:x+3
Wilma: x
Distance:32 miles
2/3(x+x+3)=32
2/3(2x+3)=32
1 1/3x+2=32
4/3x=30
x=22.5
wilma is 22.5 mph
fred is 22.5+3= 25.5 mph
Answer:
0.01
Step-by-step explanation:
Your equation is 50 / x = 5,000
You are able to switch this around to 50 / 5,000 = x
Because you know that a x b = c is the same as b x a = c
When you divide 50 by 5,000, you get 0.01
So, 50 divided by 0.01 will get 5,000
Answer:
use the distance Formula D=sqrt of {(x1-x2)^2+(y1-y2)^2}
Step-by-step explanation:
So(-5--9)^2 + (-5- -2)^2 =
(4)^2 + (-3)^2 =
16 + 9 = 25
and the square root of 25 is 5.
5 is the answer
