PLEASE ASAP HELP GIVING BRAINLIEST AND DOUBLE POINTS!!
Step-by-step explanation:
Given
Area of the cube (A) = 64 cm²
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

Find the median of 6,2,0,1,1,2,3,2,0,2,3,4,2,3,5
Answer:
2
Step-by-step explanation:
The median is the middle number when the numbers are lined up from least to greatest or greatest to least.
First, the numbers must be lined up from least to greatest.
0, 0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 5, 6
Then, find the middle number.
The middle number is 2.
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

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
