Surface area of a cylinder in terms of pi
|5z−8|=7
Can someone help me with this question I will mark you brainliest if you get the correct answer. THANKS!! :))
Answer:
z = [tex]\frac{1}{5}[/tex], z = 3
Step-by-step explanation:
The absolute value function always returns a positive value.
However, the expression inside can be positive or negative, that is
5z - 8 = 7 ( add 8 to both sides )
5z = 15 ( divide both sides by 5 )
z = 3
OR
- (5z - 8) = 7
- 5z + 8 = 7 ( subtract 8 from both sides )
- 5z = - 1 ( divide both sides by - 5 )
z = [tex]\frac{1}{5}[/tex]
As a check
Substitute these values into the left side of the equation and if equal to the right side then they are the solutions
z = 3
left side = | 15 - 8 | = | 7 | = 7 = right side
z = [tex]\frac{1}{5}[/tex]
left side = | 1 - 8 | = | - 7 | = 7 = right side
Thus z = [tex]\frac{1}{5}[/tex], z = 3 are the solutions

Which of the following could represent the scale factor of the smaller figure to the larger figure?
4:25
6pi:15pi
8:125
20pi:125pi
16pi:250pi
2:5
Answer:
It could be 2:5 or 6pi:15pi
Step-by-step explanation:
If you write the ratio of the surface area as a fraction, you would get [tex]\frac{20\pi *yd^{2} }{125\pi *yd^{2} }[/tex]. Simplifying it would leave [tex]\frac{4}{25}[/tex]. But this is NOT the answer because that is the ratio of the surface area. You have to square root it to find the scale factor. The square root is [tex]\frac{2}{5}[/tex]. The answers would be 2:5 and 6pi:15pi.
Answer:
6π : 15π
2 : 5

The graph will be a solid line with a y-intercept of negative four and a slope of seven. The graph will be shaded above the line.
The graph will be a solid line with a y-intercept of seven and a slope of negative four. The graph will be shaded below the line.
The graph will be a dashed line with a y-intercept of seven and a slope of negative four. The graph will be shaded above the line.
Answer:
It's the second description
Step-by-step explanation:
It's one of the inequality symbols for greater/less than or equal to, which means the line is solid. Then, y is greater than or equal to 7x-4 which means it will be shaded above the line.

Functions math, please help
Answer:
Slope: 2
Y-intercept: (0,-7)
Step-by-step explanation:
2(x-3)=y+1
distribute the 2 through the parentheses
2x-6=y+1
2x+6=0+1
(change the y to 0)
2x-6=1
add 6 to both sides(+6 cancels out -6)
2x=1+6
divide both sides by 2

Can someone help me with this please? In Belleville, the library is due south of the courthouse and due west of the community swimming pool. If the distance between the library and the courthouse is 9 miles and the distance between the courthouse and the city pool is 15 miles, how far is the library from the community pool?
Answer:
12 miles
Step-by-step explanation:
A right triangle is formed, where the distance between the library and the courthouse is one leg ( = 9 miles), the distance between the library and the swimming pool is the other leg (let's call it x), and the distance between the swimming pool and the courthouse is the hypotenuse ( = 15 miles).
From Pythagorean theorem:
15² = 9² + x²
225 - 81 = x²
x = √144
x = 12 miles

A circle has a radius of 6ft. What is the area of the sector formed by a central angle measuring 300 degrees
Answer:
30π ft^2 which is 94.25 ft^2 to the nearest hundredth.
Step-by-step explanation:
The area of the full circle is π * 6^2
= 36π so:
the area of the 300 degrees sector = 300 * 36 π / 360
= 30 π

What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
The expression is,
⇒ (3 + √7) (3 - √7)
Now, We can multiply the number as,
⇒ (3 + √7) (3 - √7)
⇒ (9 - 3√7 + 3√7 - 7)
