Children : 144
Adults : 51
Explanation
Step 1
Set the equations
let
x represents the number of children
y represents the number of adults
charge per child:8
charge per adult:11
total people:195
then
a)the total people is 195, so
b) the total bill was $1713,so
total childrend +total adults=173
but,
total adults cost= rate*number of adults
total children cost= rate*number of childe
replacing
Step 2
solve the equations,
a) isolate the x value from equation 81) and replace in eqaution (2)
replace in equation (2)
therefore, the number of adults is 51
b) now, replace the y value into equation (1) to find x
so, the number of children is 144
I hope this helps you
Answer:
60%
Step-by-step explanation:
Total number of people in the survey = 600
And 360 said their favorite was pepperoni.
Percentage of those who said pepperoni was their favorite will be
No. Of those who said their topping was pepperoni divided by the total number of people in the survey multiplied by 100%
That’s
360/600 x 100%
0.6 x 100%
60%
Answer:
126
Step-by-step explanation:
Answer:
We need to find the circumference, and in order to find the circumference we must know the formula for it.
Formula for circumference of a circle;
a = 2πr
Where π is the pi(3.14 or 22/7), and r is the radius which is half of the diameter.
Since we are given the diameter, we need to find the radius. So 1/2 of the diameter (26 x 1/2) = is 13
Now we just plug in the actual values in the formula:
a = 2πr
a = 2 x 3.14 x 13
a = <u>18.84 feet</u>
But now, we need to find how many revolutions it would take to get to 500 feet.
So we divide 500 feet by 18.84 feet;
500/18.84 = 26.53, around 27 revolutions.
Sadly, the cube you promised us is not shown.
IF the cube is resting on the table in the normal way ... with
two of its faces horizontal and the other four faces vertical,
then any horizontal or vertical slice is a square.
You know what's fun ? Try doing this problem with cubes of
chocolate cake, and after you make slices, look at them and
then eat them.
