Answer:
S = 8
Each side of a face is 8 units.
Step-by-step explanation:
The surface area of the cube is 384 units.
One face of the cube has an area of s^2
A cube has 6 faces
6s^2 = 384 Divide by 6
s^2 = 384 / 6
s^2 = 64 Take the square root of both sides
sqrt(s^2) = sqrt(64)
s = 8
Answer:
8 units
Step-by-step explanation:
Area of 1 side = 384 ÷ 6 = 64 sq units
Length of 1 side = sq.rt. (64) = 8 units Answer

If U = {a, b, c, d, e, f, g, h}, A= {a, b, c, d, e) and B= {c, d, e, f, g), find A-B and A nB.
here,
U = {a, b, c, d, e, f, g, h}, A= {a, b, c, d, e) and B= {c, d, e, f, g),
now,
A-B = {a,b}
A n B = { c,d,e}
Gina paid $131 for a car stereo on sale for 30% off. There was also 7% sales tax on the purchase. Find the original price of the stereo
Answer:
It would be 98.12 dollars
Step-by-step explanation:
Hope this helps. :D
The original price of the car stereo before any discounts or taxes was approximately $187.14.
We have,
Gina paid $131 for the car stereo after it was discounted by 30%.
Let's represent the original price of the stereo as "x" dollars.
The discounted price would be 70% (100% - 30%) of the original price:
Discounted price = 0.70 * x
Given that Gina paid $131, we can set up the equation:
0.70 * x = 131
Now, solve for "x" by dividing both sides of the expression by 0.70:
x = 131 / 0.70
x ≈ 187.14
So, the original price of the stereo before the discount was approximately $187.14.
There was also 7% sales tax on the purchase.
To find the sales tax amount, we calculate 7% of the original price:
Sales tax = 0.07 * 187.14 ≈ 13.10
Now, to find the total original cost before the sales tax, we add the original price and the sales tax:
Total original cost = Original price + Sales tax
Total original cost ≈ 187.14 + 13.10 ≈ 200.24
Therefore,
The original price of the car stereo before any discounts or taxes was approximately $187.14.

(a) Find the average rate of change of the function between
for x = a
and
x = a + h.
Answer:
The average rate of change of g from x = a to x = a + h is -3.
Step-by-step explanation:
We are given the function:
[tex]g(x) = -3x + 4[/tex]
And we want to determine its average rate of change of the function for x = a and x = a + h.
To determine the average rate of change, we find the slope of the function between the two points. In other words:
[tex]\displaystyle \text{Avg} = \frac{g(a + h) - g(a) }{(a + h ) - a}[/tex]
Simplify:
[tex]\displaystyle \begin{aligned} \text{Avg} &= \frac{g(a + h) - g(a) }{(a + h ) - a} \\ \\ &=\frac{(-3(a+h) + 4) - (-3a+4)}{h} \\ \\ &= \frac{(-3a -3h + 4) + (3a - 4) }{h} \\ \\ &= \frac{-3h}{h} \\ \\ &= -3\end{aligned}[/tex]
In conclusion, the average rate of change of g from x = a to x = a + h is -3.
This is the expected result, as function g is linear, so its rate of change would be constant.

A lion paced up and down the ridge 10 times. The ridge is 5 ft. 3 in. long. How far did the lion travel? (12 in.=1 ft.)
Answer:
105 ft.
Step-by-step explanation:
5 x 12 = 60
So 5 feet is 60 inches.
60 + 3 = 63
That makes the ridge 63 inches long.
When the lion went up the ridge, it traveled 63 inches.
When the lion went back down the ridge, it traveled another 63 inches, totaling 126 inches.
The lion did this 10 times.
126 x 10 = 1260
Divide 1260 by 12 to find the measurement in feet.
1260 ÷ 12 = 105

Generate a ratio table with at least two ratios equivalent to $10 per 15 tickets. Then describe how the table shows an additive structure and multiplicative structure.
Ratios are used to show proportions of related quantities.
The ratio table equivalent to $10 per 15 tickets is:
[tex]\begin{array}{cc}{Amount}&{Tickets}&10&15&20&30&30&45&40&60\end{array}[/tex]
Given that:
Ratio = $10 per 15 tickets
Using proper notation, we have:
[tex]Ratio = 10:15[/tex]
To generate a ratio table, we simply multiply or divide each part of the ratio by the same unit.
For instance,
Multiply by 2
[tex]Ratio = 20:30[/tex]
Divide the original ratio by 5
[tex]Ratio = 2:3[/tex]
A possible ratio table is:
[tex]\begin{array}{cc}{Amount}&{Tickets}&10&15&20&30&30&45&40&60\end{array}[/tex]
The additive structure
From the above table, we can see that as the amount (x) increases by 10 units, the number of tickets (y) increases by 15 units.
So, the additive structure of the above table is:
[tex](x,y) \to (x_i+10,y_i + 15)[/tex]
The multiplicative structure
The multiplicative structure simply implies that the amount (x) and the number of tickets (y) be multiplied by the same unit.
So, the multiplicative structure of the above table is:
[tex](x,y) \to n(x_i,y_i)[/tex]
