Answer:
53.3333333%
Step-by-step explanation:
Given the following question:
14 desktops
16 laptops
14 + 16 = 30
To find the answer use the formula to calculate percentages.
[tex]\frac{16}{30}\times100[/tex]
[tex]16\div30=0.533333333[/tex]
[tex]0.533333333\times100=53.3333333[/tex]
[tex]=53.3333333[/tex]
16 of 30 as a percentage is "53.3333333%."

Answer:
x=-1
Step-by-step explanation:
3x+12-8x=19+2x (combine liked terms)
-5x+12+19=2x (move variable to the left-hand side and change its sign)
-5x-2x+12=19 (combine liked terms)
-7x=19-12 (divide both sides of the equation by -7)

The slope between the points (-1,-5) and (r, -9) is 2. What is the value of r?
Answer:
r = 2
Step-by-step explanation:
slope = (y2 - y1)/(x2 - x1)
(-1, -5)
(r, -9)
-5 - (-9) / -1 - r = 2
4 / -1 - r = 2
r = -2
-1 - (-3) = 2
4 / 2 = 2

When the bathroom at your house started to leak, the plumber came to fix it. In all, he used 18 feet of pipe, which came in either 2-foot or 4-foot sections. How many of each did he use if he needed 6 pieces of pipe
4 two foot and 2 four foot
3 two foot and 3 four foot
2 two foot and 4 four foot
5 two foot and 1 four foot
Answer:
3 two foot and 3 four foot
Step-by-step explanation:
In order to find how many of each he used, you have to find how much pipe in total with the options that were given you.
(3*2)+(3*4)=6+12=18 feet of pipe
8) Choose the inequality that represents the statement.
He is older than 100.
The expression of the inequality that states his age is x > 100.
What is inequality?Inequality compares two non-equal quantities on both sides of the inequality sign. Inequalities are of four types they are:- Less than, Greater than, Less than or equal to, and Greater than or equal to. Their symbols are as follows:- <, >, ≤, ≥.
Given in the statement he is older than 100 which means his age is strictly more than 100.
Assuming his age to be x years.
∴ The inequality which represents this scenario is,
x > 100.

Hope makes 3 group of shapes
What Larger group to the shapes in a and B belong in
The shapes in the three groups are quadrilaterals
The shapes in group A and B belong to parallelograms and rectangles
How to determine the shapes?From the complete question, we can see that the shapes in the group A have opposite parallel sides and the angle between the adjacent sides is not 90 degrees.,
This means that the shapes in group A are parallelograms
Similarly, the shapes in the group B have opposite parallel sides and the angle between the adjacent sides is 90 degrees.
This means that the shapes in group A are rectangles
Hence, the shapes in group A and B belong to parallelograms and rectangles

The radius of a sphere is 3 cm. What is the sphere's volume? Round to the nearest tenth.
Answer:
113.1
I answered this question before with the exact radius, and I remember the answer being this.
Formula:
V=4
3πr3=4
3·π·33≈113.09
Hope this helps!
Answer:
Step-by-step explanation:
the answer is 113.1 cm³
The volume of a sphere of radius r is V = (4/3)πr³.
If the radius is 3 cm and the answer is to be expressed to the nearest tenth, then we get:
V = (4/3)(3.14159)(3 cm)³
= (4/3)(84.82 cm³
= 113.1 cm³

Problem 3
Answer: Choice A and Choice C
-----------------------
Explanation:
Think of stacks of coins. Let's say we had 2 stacks of 10 quarters each. The quarters are identical, so they must produce identical volumes. Those sub-volumes then add up to the same volume for each stack. Now imagine one stack is perfectly aligned and the other stack is a bit crooked. Has the volume changed for the crooked stack? No, it hasn't. We're still dealing with the same amount of coins and they yield the same volume.
For more information, check out Cavalieri's Principle.
With all that in mind, this leads us to choice C. If the bases are the same, and so are the heights, then we must be dealing with the same volumes.
On the other hand, if one base is wider (while the heights are still equal) then the wider based block is going to have more volume. This leads us to choice A.
This is long and complex, may you please get some help?

PLS HELP PLS PLS TYSM
Answer:
y = -x + 6
Step-by-step explanation:
We can plug the given point and slope into the point-slope formula and solve for the y-intercept formula.
y - y = m(x - x) <-- Point-Slope Formula
m = -1
(x,y) = (1, 5)
y - 5 = -1(x - 1)
y - 5 = -x + 1
