Answer:
1.27cm
Step-by-step explanation:
Volume(v) =100 cm
Radius(r) =5cm
Height(h) =?
Now,
Volume of cylinder (v) =¶r^2h
100 =22/7*5*5*h
100=78.57h
H=100/78.57
H=1.27cm
Height of cylinder is 1.27cm

Let y=|x|-2, where the domain is the set of integers from – 4 to 4.
What is the range?
i dont know i wish I could help.
Answer:
-2 to 2
Step-by-step explanation:
see there's the sign of absolute value around x
so even if we put a negative number in place of x we'll get a positive outcome.
for example,
if x = -4|x| = 4
if x = -3|x| = 3
and so on
so the actual domain of |x| reduces to => 0 to 4.
as you'll get the values of |x| in between 0 and 4 throughout -4 to 4.
where the smallest value is 0 and largest is 4.
for range,
I'll just put these smallest and largest values in place of x and solve for domain
at x = 0y= |0| - 2
y = -2
at x = 4y = |4| - 2
y= 4 - 2
y = 2
so, the range of the function becomes -2 to 2.

Annika borrowed a book from the library and forgot to return it on time. The library charges $0.25 per day for the first four days and $0.30 per day for all of the remaining days. If Annika had to pay the library $4.00, how many days late was her book?
please help me.
The number of days the book was late is 14 days.
The given parameters include;
let the number of days late before she returned the book = xThe following algebraic equation will be set to calculate the number of days the book was late before it was returned;
[tex]0.25(4) + (x - 4)0.3 = 40\\\\[/tex]
simplify the equation as follows;
[tex]1 + 0.3x - 1.2 = 4\\\\[/tex]
collect similar terms together;
[tex]0.3x = 4.2\\\\[/tex]
divide through by 0.3
[tex]x = \frac{4.2}{0.3} \\\\x = 14 \ days[/tex]
Thus, the number of days the book was late is 14 days.

Find how many days late was her book
The total days late is 14 days
charges per day for first 4 days = $0.25
charges per day for the remaining days = $0.30
Total amount Annika paid = $4.00
let x = number of days of the remaining days
Total amount paid = Amount paid for first 4 days + amount paid for remaining daysAmount paid for first 4 days = $0.25 × 4
= $1
Amount paid for remaining days = 0.30 × x
= 0.30x
Total amount paid = Amount paid for first 4 days + amount paid for remaining days
4 = 1 + 0.30x
4 - 1 = 0.30x
3 = 0.30x
x = 3/0.30
x = 10 days
Total days late = 4 days + 10 days
= 14 days

-2^2(-5x+10)=100
Answer:
[tex]x=7[/tex]
Step-by-step explanation:
Hi there!
[tex]-2^2(-5x+10)=100[/tex]
Solve -2^2:
[tex]-4(-5x+10)=100[/tex]
Divide both sides by -4:
[tex]\displaystyle \frac{ -4(-5x+10)}{-4}=\frac{100}{-4} \\\\-5x+10=-25[/tex]
Subtract 10 from both sides:
[tex]-5x+10-10=-25-10\\-5x=-35[/tex]
Divide both sides by -5:
[tex]\displaystyle \frac{-5x}{-5} = \frac{-35}{-5} \\\\x=7[/tex]
Therefore, x = 7.

To find range we first need to find the highest number and the lowest number
3 , 4 , 4 , 7 , 7 ,7 ,7 7, 8
least number = 3
highest number = 8
now substract the lowest number from the highest to get the range
= 8-3
= 5

what is 640 divided by 20
Answer:
640/20 is 32
hope it's helpful
When the number 640 is divided by the number 20, the result is 32.
To divide 640 by 20, we perform long division or use the concept of division as the inverse of multiplication. By dividing 640 by 20, we are essentially finding how many times 20 can be evenly divided into 640.
On Dividing 640 by 20 yields a quotient of 32. This means that 20 can be divided into 640 exactly 32 times, without any remainder.
Thus, 640 divided by 20 is equal to 32. In simpler terms, if we distribute 640 items into 20 groups, each group will contain 32 items.
