Anyone know how to do this??
Answer:
its square roots
Step-by-step explanation:
you gotta take the "answer" so in this case its 3m with something to the power and the square root of 7, which is 2.6. Then you take 3m and add it to 2.6, which is 5.6m. Then you take 5.6 and take the to the 17th power and do that which is 5.2e+12. You simplify that and thats the answer. I'm pretty sure.
Which one of these is not a 3D shape?
a.) Pyramid
b.) Cone
c.) Sphere
d.) None of these
Answer: d all others are 3d
Step-by-step explanation:
Answer:
D) None of the above
Step-by-step explanation:
This is because all of the shapes above are examples of 3D shapes. A 3D shape would have the dimensions of length and width and height. However a 2D shape would only have the dimensions of length and width.
An example of a 2D shape is a rectangle. as it consists of a length and a width, but does not have a height.
On the other hand a £D shape such as a cube would have a length, width and a height.

Calculators cannot display repeating decimals. Calculators always round. Yuri's calculator displays decimals to 5 places. He uses his calculator to find the decimal equivalent for each of the fractions below. For each number, choose what his calculator will display as the decimal equivalent. Then choose whether or not this is the exact decimal equivalent.
1/9
Calculator display for 1/9:
Is this the exact decimal equivalent?
7/9
Calculator display for 7/9:
Is this the exact decimal equivalent?
9/10
Calculator display for 9/10:
Is this the exact decimal equivalent?
1/9 = 0.111111111..., No
7/9 = 0.777777...8, No
9/10 = 0.9, Yes
Dividing by a non-factor of 9 by 9 will always result in an infinite decimal, similar to dividing a non-factor of 3 by 3 or a non-factor of 7 by 7.
However, dividing a number by 10 will simply move the decimal one value to the right, so 9.0 divided by 10 is 0.90.

Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi and enter your answer as a decimal.
Answer:
V≈3.09×108
Step-by-step explanation:
Shape: Cylinder
Solved for volume
Radius: 333
Height: 888
Formula: Radius, Height
Exact answer: V≈3.09×108
Hope this helps.
The volume of the cylinder is = 98,469,432π
Calculation of volume of cylinderThe radius of the cylinder = 333
The height of the cylinder = 888
Therefore the volume is = ?
The formula for the volume of cylinder = πr²h
V = π× 333² × 888
V = π × 110,889× 888
V = 98,469,432π
Therefore, the volume of the cylinder is = 98,469,432π

Becca sells bracelets for $9 each. She has to pay $4.35 for the materials for each bracelet. How much money does she make from each bracelet after she pays herself back for the materials? How much money does becca make from the sale of 15 bracelets?
i am marking brainiest
Answer:
$4.65$69.75Step-by-step explanation:
How much money she makes from each bracelet:
9-4.35=$4.65
How much money she makes from the 15 bracelets:
4.65 x 15= $69.75
Answer:
Part 1: 4.65
Part 2: 69.75
Step-by-step explanation:
The first question is "How much money does she make from each bracelet after she pays herself back for the materials?"
To answer that, we must find how much she is selling them for ($9) and subtract the cost of the materials from it ($4.35), which equals 4.65
The second question is How much money does becca make from the sale of 15 bracelets?
In other words, they are only asking for the profit made which means they don't want the materials used cost included. So we can use the answer from before and multiply by 15, so 4.65*15=69.75.
Hope that makes it clear, and good luck with studies :)

The central angle of an arc measures 120° The radius of the circle measures 3 cm what is the area of the sector to the nearest hundredth of a square centimeter
Answer:
The area of the sector should be 9.42[tex]cm^2[/tex] .
Step-by-step explanation:
-The formula for finding the area of a sector:
[tex]A = \frac{Arc}{360} \pi r^2[/tex]
-Next use the arc measure and the radius in order to solve and get the answer:
[tex]A = \frac{120\textdegree}{360\textdegree}\pi 3^2[/tex]
-Solve:
[tex]A = \frac{120\textdegree}{360\textdegree}\pi 3^2[/tex]
[tex]A = \frac{120\textdegree}{360\textdegree}\pi \times3^2[/tex]
[tex]A = \frac{1}{3} \pi \times 3^2[/tex]
[tex]A = \frac{1}{3} \pi \times 9[/tex]
[tex]A = 3\pi \approx 9.424[/tex]
-Round to the nearest hundredth:
[tex]A \approx 9.42[/tex]

Which set of numbers can represent the side lengths, in inches, of an acute triangle? 4, 5, 7 5, 7, 8 6, 7, 10 7, 9, 12
oof
Answer:
4 5 7
Step-by-step explanation:
i know it
Answer:
Set B i.e., 5 , 7 , 8 represent the side of acute angled triangle.
Step-by-step explanation:
Given: Set of numbers.
To find: Set that represent sides of an acute angled traingle.
We use the following result:
When given 3 triangle sides then to determine if the triangle is acute angled , right angled or obtuse angled.
First find Square all 3 sides, then Sum the squares of the 2 shortest sides and then Compare the sum to the square of the last side.
if sum > Square of last side ⇒ it is Acute Triangle
if sum = Square of last side ⇒ it is Right Triangle
if sum < Square of last side ⇒ it is Obtuse Triangle
a). 4 , 5 , 7
4² = 16 , 5² = 25 , 7² = 49
16 + 25 = 41
∵ 41 < 49
⇒ It is an Obtuse Traingle.
b). 5 , 7 , 8
5² = 25 , 7² = 49 , 8² = 64
25 + 49 = 74
∵ 74 > 64
⇒ It is an acute Triangle.
c). 6 , 7 , 10
6² = 36 , 7² = 49 , 10² = 100
36 + 49 = 85
∵ 85 < 100
⇒ It is an Obtuse Triangle.
d). 7 , 9 , 12
7² = 49 , 9² = 81 , 12² = 144
49 + 81 = 130
∵ 130 < 144
⇒ It is an Obtuse Triangle.
Therefore, Set B i.e., 5 , 7 , 8 represent the side of acute angled triangle.

Answer:
the median is 80.5
Step-by-step explanation:
first we put them in order
75,76,77,79,80,81,85,86,90,91
the median is the middle number...however, in cases where there are an even number of numbers, ur gonna have 2 middle numbers....so u take the average of those 2 numbers...basically, u add them and divide by 2.
So we have 2 numbers in the middle.....we add them and divide by 2 to get the median.
(80 + 81) / 2 = 161/2 = 80.5 <== the median

Solve the given system by substitution.
n=5m
n=2/3 m-13
Answer:
n = -15 and m = -3
Step-by-step explanation:
To solve the given system of equation, we will follow the steps below:
n = 5m ----------------------------------------------------------------------------(1)
n = [tex]\frac{2}{3} m -13[/tex] ---------------------------------------------------------------------(2)
substitute for n= 5m in equation (2)
5m = [tex]\frac{2}{3} m -13[/tex]
subtract [tex]\frac{2}{3} m[/tex] from both-side of the equation
5m - [tex]\frac{2}{3} m[/tex] = [tex]\frac{2}{3} m[/tex] - [tex]\frac{2}{3} m -13[/tex]
At the right-hand side of the equation [tex]\frac{2}{3} m[/tex] will cancel-out leaving us with just -13
5m - [tex]\frac{2}{3} m[/tex] = -13
[tex]\frac{15m - 2m }{3}[/tex] = -13
[tex]\frac{13m}{3}[/tex] = -13
multiply both-side of the equation by 3
3 × [tex]\frac{13m}{3}[/tex] = -13 × 3
At the left-hand side of the equation 3 will cancel-out 3 leaving is with just 13m
13m = -39
Divide both-side of the equation by 13
13m/13 = -39/13
m = -3
substitute m = -3 in equation (1)
n = 5m
n = 5 (-3)
n = -15
Therefore, n = -15 and m = -3
