Two times the sum of a number and twelve is 40. What is the number?
Answer:
8
Step-by-step explanation:
n= that number
2(n+12)=40
2n+24=40
-24 -24
2n=16
2n/2=16/2
n=8
Answer:
the number is 8
Step-by-step explanation:
2(12 + n) = 40
24 + 2n = 40
2n = 16
n = 8

Use the domain {-1, 0, 1, 2, 3} and plot the points on the graph that would best satisfy the equation. The bold grid marks represent one unit, the horizontal red line represents the x-axis while the vertical red line represents the y-axis.
y = 2x
Answer:
Plot the following points on the graph
[tex](-1, \frac{1}{2})[/tex], (0, 1), (1, 2), (2, 4), (3, 8)
Step-by-step explanation:
If the equation for the line is y = [tex]2^{x}[/tex], whatever the power/exponent "x" equals, then y is equal to however many times 2 is multiplied by x.
For example, if our domain is {-1, 0, 1 , 2, 3}
then we would plug in each x value into the exponent to find the y-value in order to plot the points to solve the problem.
If x = -1, then y = 1/2. **If there is an a negative exponent it would get turned into a positive fraction with the denominator as the positive version of that number.
[tex]y = 2^{-1} = \frac{1}{2^{1} } = \frac{1}{2}[/tex]
If x = 0, then y = 1
**When the exponent is 0, the number automatically equals 1.
If x = 1, then y = 2.
If x = 2, then y = 4
If x = 3, then y = 8
So you would plot the following coordinates on the graph:
[tex](-1, \frac{1}{2})[/tex]
(0, 1)
(1, 2)
(2, 4)
(3, 8)
A 10 2/3 -inch long pipe is cut into 8 equal length pieces. How long is each piece?
Answer:
Each peice is 1 1/3 (4/3) long.
Step by step explanation:
10 2/3 divided by 8
10 2/3 = 32/3
32/3 divided by 8 = 32/3 x 1/8
32 times 1 = 32, 3 times 8 = 24 =32/24
32/24 in simplest form is 4/3 (aka 1 1/3)
Hope this helped! :)

A golf ball is hit on the moon so that
the height of the ball (in feet) is modeled by the
function h(x)=-2.7t^2+21.6t after t seconds.
The ball will land in t = ? seconds
I am just not sure if I did this properly. My professor hasn't really gone over when to use the range equation but I would assume range would equal the distance traveled therefore can be used for this problem. If not the how would I go about solving this? I did 1/6*9.8=1.63 for g on the moon Then used R=(Vi^2sin2theta)/g so on the moon R=((28^2)sin2*35)/1.63=452m

What is mean by Fraction?
A fraction is a part of whole number, and a way to split up a number into equal parts.
Or, A number which is expressed as a quotient is called fraction.
It can be written as the form of p : q, which is equivalent to p / q.
Given that;
A robot can complete 7 tasks in 2/5 hour.
Each task takes the same amount of time.
Now,
Since, 7 tasks = 2/5 hour
So, 1 tasks = 2 / 5×7
= 2 / 35 hour
Thus, The robot take 2 / 35 hour to complete one task.
And, 2/5 hour = 7 tasks
So, 1 hour = 7 x 5 / 2
= 35 / 2
Thus, The robot complete 35/2 tasks in one hour.
Therefore,
a) The robot take 2 / 35 hour to complete one task.
b) The robot complete 35/2 tasks in one hour.

You decide to buy a 60 in plasma-screen TV. You borrow $4500 from the
electronics store at 1.9% per month simple interest, with no payments due for
2 years from the date of purchase.
How much will you owe on the loan after 15 months? Round your answer to
the nearest whole dollar.
A. $5783
B. $5355
C. $6552
D. $4586
The answer is A. $5,783
Explanation:
= $4,500.00(1 + [0.019 * 15])
= $4,500.00(1 + 0.285)
= $4,500.00(1.285)
= $5,782.50
Round $5,782.50 to the nearest whole dollar and you get $5,783

Write an equation of the line, in point-slope form, that passes through the two given points. points: (-3,18). (12,-12)
Answer:
y = -2x + 12
Step-by-step explanation:
First, find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-12 - 18) / (12 + 3)
-30 / 15
= -2
Then, plug this and a point into y = mx + b and solve for b:
y = mx + b
-12 = -2(12) + b
-12 = -24 + b
12 = b
Then, plug in the slope and b into y = mx + b
y = -2x + 12 is the equation of the line

What causes a stars to shine brightly?
Answer:
Stars are actually exploding when you see them, so the light is produced from the explosion.
Step-by-step explanation:
:)
Answer: Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars.
Step-by-step explanation:
In most stars, like our sun, hydrogen is being converted into helium, a process that gives off energy that heats the star, this energy also causes the star to shine brightly.
