What is the radius of a cylinder that has a volume of 500 ft ³ and that is 10 ft tall?
Answer:
The answer is 3.98942, rounded its 3.99.
Step-by-step explanation:
Answer:
3.99 ft
Step-by-step explanation:
Volume of a cylinder = πr²h
π = 3.14
volume = 500 ft³
height = 10 ft
πr²h = 500
3.14×r²×10 = 500
r² = 500/3.14×10
= 15.92..
= √15.92
r = 3.9899.. ≈ 3.99 ft

1) In the figure below, m_2 = 60°. Find the measure of each angle. Write which postulate(s) or
theorem(s) you used.
a ) angle 1
b) angle 2
c) angle 8
Answer:
Step-by-step explanation:
From the picture attached,
Two lines are the parallel lines and a third line (transversal line) is intersecting these parallel lines.
m∠2 = 60°
a). m∠1 + m∠2 = 180°
m∠1 + 60° = 180°
m∠1 = 180° - 60°
m∠1 = 120°
b). m∠2 = 60° [Given]
c). m∠2 = m∠8 = 60° [Alternate exterior angles are equal]
Melissa has started training for a race. The first time she trains, she bikes 5 miles. Each subsequent time she trains, she bikes 0.5 mile farther than she did the previous time.
A. Use summation notation to write an arithmetic series to represent the total distance Melissa has biked after she has trained n times.
B. Use the formula for a partial sum of the series you wrote in part a, above, to answer this question: What is the least number of times Melissa must bike for her total distance biked during training to exceed 60 miles? (3 points)

Answer:
A. d = ∑[k=1,n] (4.5+0.5k)
B. 9
Step-by-step explanation:
A) The series has first term 5 and common difference 0.5. The general term is given by ...
an = a1 +d(n -1)
an = 5 + 0.5(n -1) . . . . substitute numbers for this series
an = 4.5 +0.5n . . . . . . simplify
The sum is the sum of these terms:
[tex]\displaystyle \boxed{d_n=\sum_{k=1}^n(4.5+0.5k)}[/tex]
__
B) The sum of terms of an arithmetic series is the average of the first and last, multiplied by the number of terms. We want to solve for n to make the sum greater than 60.
[tex]\displaystyle d_n=\frac{n}{2}(5 +4.5 +0.5n)\\\\\dfrac{n}{2}(9.5+0.5n)>60\\\\n(19+n)>240\qquad\text{multiply by 4}\\\\n^2+19n+9.5^2>240+9.5^2\qquad\text{complete the square}\\\\n+9.5>\sqrt{330.25}\qquad\text{square root}\\\\n>18.17-9.5=8.67\qquad\text{positive root, subtract 9.5}[/tex]
Melissa's total distance will first exceed 60 miles the 9th time she trains.
Answer:
A. d = ∑[k=1,n] (4.5+0.5k)

What is the area of this triangle?
Answer:
The answer would be 14 units.
Step-by-step explanation:
Count each of the units to find the height and base.
Height - 4 units
Base - 7 units.
Then use the formula A = 1/2*h*b
A = 1/2*7*4
A = 1/2*28
A = 14 units.
The area of the given triangle is 14 units².
Use the concept of the triangle defined as:
A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.
And area of triangle = (1/2)x base x height
In the given triangle:
Width = 5 units + 2 units
Width = 7 units
Height = 2 units + 2 units
Height = 4 units
Put the values into the above formula of area,
Area of triangle = (1/2)x 7 x 4
Area of triangle = 14 unit²
Hence,
The area of the given triangle is 14 units².

What is the approximate surface area of a cylinder that's base has a radius of 2, and it's lateral rectangle has a length of 6.28, and a width of 4?
Answer:
Surface area of cylinder = 50.26 unit² (Approx.)
Step-by-step explanation:
Given:
Radius of base r = 2 units
Width of lateral rectangle = 4 units
Length of lateral rectangle = 6.28 units
Find:
Surface area of cylinder
Computation:
Surface area of cylinder = 2[Area of base] + Area of lateral rectangle
Surface area of cylinder = 2[πr²] + [l][b]
Surface area of cylinder = 2[(22/7)(2)²] + [6.28][4]
Surface area of cylinder = 2[(22/7)(4)] + 25.12
Surface area of cylinder = 25.14 + 25.12
Surface area of cylinder = 50.26
Surface area of cylinder = 50.26 unit² (Approx.)

A rectangle has a height of 5 inches and a area of 35 squared inches what is the length of the base of the rectangle? Please help I dont get it.
Answer:
The length of the base of the rectangle is 7 inches
Step-by-step explanation:
The Area of the rectangle can be found out by multiplying length with the breadth
Area= length * breadth
35 squared inches= x *5
5x= 35
x= 35/5
x= 7inches
Hence the length of the base of the rectangle is 7 inches.
If the area and one side are known then we can simply find the 2nd side by simply substituting x in its place and solving the equation.

Let f(x) = 1/x and g(x) = x²-
6x. What
two numbers are not in the domain of fºg?
Separate your answers with a comma.
Enter the correct answer.
Step-by-step explanation:
f°g=[tex]f(g(x))[/tex]
[tex]g(x)=x^2-6x[/tex]
[tex]f(x)=1/x[/tex]
[tex]f(g(x))=[/tex][tex]\frac{1}{x^2-6x}[/tex]
if the denominator is zero the number is undefined which makes it not in the domain of the function
set [tex]x^2-6x[/tex] equal to 0
the values for x is 0 or 6
so the only value that is not in the domain of f°g is 0 and 6

Answer:
3.33
Step-by-step explanation:
each cube represents 1, so each flat represents 0.1 and each unit represents 0.01. so if there are 3 of each, it would be 3+0.3+0.03 which equals 3.33
Answer:
3.33
Step-by-step explanation:
Each cube in this picture is equal to 1 unit as the diagram in the upper right corner shows.
We have 3 cubes so -> 1 + 1 + 1 = 3
We also have 3 squares that are 1/10th of a cube.
1/10 * 1 = 0.1 so each square is equal to 0.1 unit.
We have 3 squares so it would be 0.1 + 0.1 + 0.1 = 0.3
We have 3 tiny squares that are 1/100th of a cube.
1/100 * 1 = 0.01 so each tiny square is equal to 0.01 unit.
We have 3 tiny squares so it would be 0.01 + 0.01 + 0.01 = 0.03
Add everything up: 3 + 0.3 + 0.03 = 3.33

Sue wants to know whether wearing sunglasses improves driving performance. If she uses an independent groups design, she would manipulate the variable by randomly requiring half the drivers to drive with sunglasses and the other half to drive without sunglasses. having all drivers first drive without sunglasses and then with sunglasses. having half the drivers first drive without sunglasses and then with sunglasses and having the other half first drive with sunglasses and then without sunglasses. requiring all drivers to first drive with sunglasses and then without sunglasses.
Answer:
randomly requiring half the drivers to drive with sunglasses and the other half to drive without sunglasses.
Step-by-step explanation:
When employing an independent group design in a research or experimental study, the different groups in the study are assigned entirely different subjects such that, subjects in the treatment group are different from those in the control group. Therfore, adopting an independent group design in the scenario described above means diving the subjects into two at random with one half driving with sunglasses and the other half having to drive without it.

We have the equation to find this as follows;
D = √((x2-x1)^2 + (y2-y1)^2
where (x1,y1) = (-4,2) and (x2,y2) = ((2,4)
so we have the length calculated as follows;
D = √(2-(-4))^2 + (4-2)^2
D = √6^2 + 2^2
D = √36 + 4
D = √40
D = 6.3 units
Mario's grape vine grows 7.5 inches in 3 weeks. At this rate, how much will the grape vine grow in 15
weeks?
Answer:
It will grow 37.5 inches
Step-by-step explanation:
It grew 7.5 in 3 weeks. Divide 7.5 by 3 and you'll get 2.5. So that means every week it grows 2.5 inches. So multiply 2.5 x 15 and you'll get 37.5 inches
