Now
The volume of the cube (V)
[tex]v \: = {a}^{ \frac{3}{2} } \\ v \: = 64 ^{ \frac{3}{2} } \\ v = 8 ^{ \frac{3 \times 2}{2} } \\ v \: = {8}^{3} \\ v = 512cm ^{3} [/tex]
Hope it will help :)❤
Answer:
512 cm³Step-by-step explanation:
Let us understand the letters in the formula first. The rest is really quite simple.
V = volume
A = area
Let's substitute the known area in for A
V = 64^3/2
Solve for V
64^3/2 = 512
V = 512
Hence, the volume of the cube is 512 cm³
HELP HELP HELP HELP HELP HELP HELP
Answer:
Hi,
In a square, all sides are equal.
The area is obtained by multiplying one side by another side.
So, A = L^2
A = Area
L = length of a side
24ft^2 = L^2
L = square root(24) = 4.9
L = 4.9
We can say x^2 = 24
And the length of one side is therefore 4.9
A college student takes the same number of credits each semester. Before beginning college, the student had some credits
earned while in high school. After 2 semesters, the student had 34 credits, and after 4 semesters, the student had 58
credits.
Answer:
The student gets 12 credits per semester, and started college with 10 credits that he earned in high school.
Step-by-step explanation:
Given that a college student takes the same number of credits each semester, and that before beginning college, the student had some credits earned while in high school, while after 2 semesters, the student had 34 credits, and after 4 semesters, the student had 58
credits, to determine how many credits she obtains each semester and how many credits she had at the beginning of college, the following calculation must be performed:
(58 - 34) / 2 = X
24/2 = X
12 = X
34 - 12 x 2 = X
34 - 24 = X
10 = X
Thus, the student gets 12 credits per semester, and started college with 10 credits that he earned in high school.
Answer:
C(t) = 12t + 10
Step-by-step explanation:
We're given two data points, (2,34) and (4,58). We want to find an equation of the form C(t)=mt+b where m is the rate of change and b is the y-intercept.
First, we find the rate of change.
m=(58−34)/(4−2)
m=24/2
m=12
This rate of change means that the student earns 12 credits each semester.
Finally, we need to solve the equation C(t)=12t+b for b, or the y-intercept. We do this by plugging in one of our data points. We'll use (2,34).
C(t)=12t+b
34=12(2)+b
b=34−24
b=10
This y-intercept means that the student earned 10 credits in high school.
Now that we've found m and b based on the given data, we find that the equation is C(t)=12t+10.

Working together, two pumps can drain a certain pool in 6 hours. If it takes the older pump 15 hours to drain the pool by itself, how pump to drain the pool on its own?
Answer:
10
Step-by-step explanation:
Rate of drainage for pump A and B = [1 pool drained]/[6 hours]
Rate of drainage for pump A (older pump) = [1 pool drained]/[15 hours]
Rate for pump B (newer pump) = [1 pool drained]/[t hours]
Thus, adding the rate of drainage of A and B,
1/t + 1/15 = 1/6
t=10

julio has $10 in a bank account. each week he earns $125. let x represent the number of weeks and f(x) represent the account balance,
Answer:
f(x) =10+125x
Step-by-step explanation:
Given data
Account Blance= $10
Weekly earning= $125
Let x be the number of weeks
and the account Balance after x weeks be f(x)
Hence the expression for the account balance is
f(x) =10+125x
The price of a CD player was reduced from $80 to $52. What was the percent decrease in the price of the CD player?
Answer:
35%
Step-by-step explanation:
The cd players price decresed by 35%
The percentage decrease is given by the equation P = 35 %
What is Percentage Error?
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage error is the difference between the measured value and the true value , as a percentage of the true value
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Given data ,
Let the percentage decrease be P
Let the original cost of the CD player be A = $ 80
Let the reduced price of the CD player be B = $ 52
Now , the equation will be
Percentage Decrease = [ ( | Measured Value - True Value | ) / True Value ]x 100
Substituting the values in the equation , we get
Percentage decrease P = [ ( 80 - 52 ) / 80 ] x 100
On simplifying the equation , we get
Percentage decrease P = ( 28/80 ) x 100
Percentage decrease P = 0.35 x 100
Percentage decrease P = 35 %
Therefore , the value of P is 35 %
Hence , the percentage decrease is 35 %

According to the exterior angle theorem, the angle ∠ADC is equal to the sum of ∠C and ∠B. Therefore:
120 = (15 + 5) + (22x + 4)
Combine like terms:
120 = 37x + 9
Subtract 9 from both sides:
111 = 37x
Divide both sides by 37:
x = 3.
