Answer:
-4/3
Step-by-step explanation:
2^(8x-8)=4^7x
2^8x-8=4^7x
2^8x-8=4^2×7x
8x-8=2×7x
8x-8=14x
-8=14x-8x
-8=6x
-8/6=x
-4/3=x
x=-4/3

Answer:
The area of the lateral surface of the cube is 12.96 cm²
Step-by-step explanation:
The lateral surface area
4 × (1.8 cm)²
An objects lateral surface are the surfaces of the object that exclude the top and bottom surfaces
In a cube, the lateral surface are the vertically oriented (with respect to the base and the top which are then oriented horizontally) surfaces of the cube
Therefore, the lateral surface area of the cube consist of four vertically oriented equal sized faces, each with side 1.8 cm
The area of the lateral surface of the cube = The area of the four vertically oriented faces of the cube
∴ The area of the lateral surface of the cube = 4 × 1.8 cm × 1.8 cm = 12.96 cm.²
Equivalent expression for m-(8-3m)
Answer:
4m-8
Step-by-step explanation:
answer
Answer:
4m - 8
Step-by-step explanation:
Given expression,
→ m - (8 - 3m)
Simplifying the expression,
→ m - (8 - 3m)
→ m - 8 + 3m
→ 4m - 8
→ 4(m - 2)
Hence, answer is 4m - 8.
What is the slope of the line?
Answer:
Step-by-step explanation:
by inspection.. ( looking at the graph) we can see that the slope is down hill. so it's going to be negative and also slope = rise / run [rise is negative in this question] soo ... i'm looking carefully to see where the line is crossing the grid marks exactly .. it looks like to me (-3,1) and (2,-3) you tell me if that looks right... if it does .. then the rise / run is 4/5 and this is a negative slope sooo
- 4/5

A company rents two storage units. Both units are cube- shaped. What is the difference in volume of the two storage units? Note that the volume of a cube a square is s(2) , where is the side length. Explain.
Answer:
The difference between their volumes is [tex]237.375ft^3[/tex]
Step-by-step explanation:
The attachment completes the question.
For cube 1:
[tex]s_1 = 8ft[/tex]
For cube 2:
[tex]s_2 = 6.5ft[/tex]
Required
The difference in their volumes
First, we calculate the volume of box 1
[tex]V_1 = s_1^3[/tex]
Substitute 8 for s1
[tex]V_1 = 8^3[/tex]
[tex]V_1 = 512ft^3[/tex]
Next, we calculate the volume of box 2
[tex]V_2 = s_2^3[/tex]
Substitute 6.5 for s2
[tex]V_2 = 6.5^3[/tex]
[tex]V_2 = 274.625ft^3[/tex]
The difference is then calculated as:
[tex]Difference = |V_1- V_2|[/tex]
[tex]Difference = |274.625- 512|[/tex]
[tex]Difference = |-237.375|[/tex]
[tex]Difference = 237.375[/tex]
Hence, the difference between their volumes is [tex]237.375ft^3[/tex]
A family went to a restaurant for dinner. The subtotal for the meal including tax is $65.90. The family decided to leave a 20% tip. How much did the family pay total including tip?
Answer:
$79.08
Step-by-step explanation:
Find 20% of 65.90. 20% as a decimal is 0.20. Multiply 0.2 and 65.90.
65.90 x 0.20 = 13.18
Add 13.18 to the original price.
13.18 + 65.90 = 79.08

Answer:
[tex]x = 5[/tex]
Step-by-step explanation:
[tex] {2}^{2x - 3} + 52 = 180[/tex]
[tex] {2}^{2x - 3 } = 128[/tex]
[tex] {2}^{2x - 3} = {2}^{7} [/tex]
[tex]2x - 3 = 7[/tex]

What is the solution to this inequality?
-6x + 5 > -1
A: x > -1
B: X 1
D: X < -1
Step-by-step explanation:
-6x + 5 > -1
-6x > -6 (subtract 5 on both sides)
x < 1 (divide -6 on both sides, flip the sign)
Hence the answer is x < 1.

What is the area of the given circle? Use 3.14 for it.
A)
56.52 cm2
B)
254.34 cm2
C)
324.09 cm2
D)
1017.36 cm2
Answer: B. 254.34 cm^2
Step-by-step explanation:
The area of a circle is pi times the radius squared.
Using the diameter we have to find the radius.
The diameter is two times the radius meaning that the radius is half the diameter.
18/ 2 = 9
The radius will be 9 cm
Now using the formula v= pi * r^2 , input the value for pie and the radius and solve for v the volume
v = 3.14 * 9^2
v= 3.14 * 81
v = 254.34 cm^2
Answer:
The answer would be B) 254.34 cm2

The ratio of males to females was 4:5. If there are 180 people at the fair how many males
are there?
9514 1404 393
Answer:
80
Step-by-step explanation:
Let m represent the number of males. Then you have ...
m/(180 -m) = 4/5
5m = 4(180 -m) . . . . cross multiply
9m = 720 . . . . . . . . add 4m, simplify
m = 80 . . . . . . . . . . divide by 9
The number of males at the fair was 80.
