Answer:
n = -56
Step-by-step explanation:
1/8n=−7
1/8 * n = −7
n * 1/8 = −7
n/8 = −7
8 * n/8 = -7 * 8 ==> multiply each side by 8 to isolate n and remove fractions
n = -56
__________________________________________________________
Hello! In this question, we are going to solve for the variable "n".
__________________________________________________________
Explanation:
In the question, we were given the equation:
[tex]\frac{1}{8} n=-7[/tex]
We will solve for the variable "n" by getting it by itself, which would then be our "n" value.
__________________________________________________________
Solve:
Let us solve for n:
[tex]\frac{1}{8} n=-7\\\\\text{To get "n" by itself, we will multiply by 8 to eliminate the fraction}\\\text{Whatever you do to the left side of the equal sign, you do to the right}\\\text{Multiply both sides by 8}\\\\8\times\frac{1}{8} n=-7\times8\\\\n=-56\\\\\text{Since "n" is now by itself, we can't simplify any further, therefore our }\\\text{ "n" value would be \boxed{-56}.}[/tex]

[tex]\boxed{n=-56}[/tex]

What is the volume of the composite figure?
Answer:
1428 in³
Step-by-step explanation:
To find the volume of this figure, we will need to use two formulas. The volume of a Rectangular Prism [tex](A=l*w*h)[/tex] and volume of a triangular prism.
[tex](A=\frac{1}{2} (b*h )[/tex]
If we look at the Rectangular Prism, we can find that l = 17, w = 8, and h = 5. Multiply these to find the volume:
17 × 8 × 5 = 680 in³.
Solving for the triangular prism gives us:
A = 1/2 (11 × 8 × 17)
A = 748.
Add these two volumes to find the volume of the composite figure:
748 + 680 = 1428 in³

-10 + 15xy = 20 Direct and inverse variation. constant of variation (k)
Answer:
This is an inverse variation, and the constant of variation is k = 2.
Step-by-step explanation:
Direct variation is something like:
y = k*x
Where k is the constant of variation.
So as x increases also increases y.
Inverse variation is something like:
y = k/x
k is the constant of variation.
In this case, if x increases, y decreases.
Now let's look at the equation:
-10 + 15*x*y = 20
Let's isolate y in one side of the equation:
15*x*y = 20 + 10 = 30
15*x*y = 30
y = 30/(15*x) = (30/15)/x = 2/x
y = 2/x
Then we can conclude that this is an inverse variation, with a constant of variation equal to 2.

Which value of "X" is a solution to this equation?
4x2 +22x +10
Answer:
Two solutions: X = -5 and X = -0.5
Step-by-step explanation:

Akiko is making a pizza. The radius of the pizza is 19 inches. What is the circumference of the pizza (use 3.14 for pi and round to nearest tenth)?
Answer:
≈119.3
Step-by-step explanation:
The area for circumference is as follows:
[tex]C = 2\pi r\\or\\C = d\pi[/tex]
The above equations mean the same thing, because the diameter is just 2 times the radius.
Anyhow, we insert this value into the equation...
[tex]C = 2\pi(19)\\C = 38(3.14)\\C = 119.32\\[/tex]

Grogg skips count by 5 starting at x. The sum of the first 5 numbers he says is 65. What is the value of x?
Answer: 11
Step-by-step explanation:
Let the 5 numbers be x,x+1,x+2,x+3 and x+4.
Therefore,
x + x+1 + x+2 + x+3 + x+4 = 65
5x + 10 = 65
5x = 65 - 10
5x = 55
x = 55/5
x = 11
Therefore, the 5 numbers are 11, 12, 13, 14 and 15.
The first number is 11

Diagonals of a parallelogram bisect each otherGiven vertices:
(-2,-1), (1,3), (6,3), (3,-1)Plot the points.
We see the diagonals are:
(-2,-1) (6,3) and (1,3), (3,-1)The midpoint of any diagonal is the intersection of the diagonals.
Use midpoint formula to find the coordinates:
x = (x₁ + x₂)/2 = (-2 + 6)/2 = 4/2 = 2y = (y₁ + y₂)/2 = (-1 + 3)/2 = 2/2 = 1The point is (2, 1)

The time it takes to travel to a destination varies inversely with the average speed. It takes two hours when the average speed is 40mph.
If the average speed changes to 80mph, what is the new travel time?
Answer:
1 hour
Step-by-step explanation:
The time it takes to travel to a destination varies inversely as its speed
T= k/S
K= TS
Time= 2 hours
Speed= 40mph
K= 2×40
= 80
Therefore if the average speed changes to 80mph then the new travel time can be calculated as follows
T= 80/80
= 1 hour
Hence the new travel time is 1 hour
What is the slope of the line that passes through the points (3, -2) and (9, -2)?
a) 0
b) 3
c) -3
d) undefined
Answer:
a) 0
Step-by-step explanation:
the equation of the slope (m) for a line from two points is given as (y2-y1)/(x2-x1)
we are given the points (3,-2) and (9,-2)
we can label the points:
x1=3
y1=-2
x2=9
y2=-2
now substitute into the equation:
m=(-2--2)/(9-3)
simplify
m=(-2+2)/6
m=0/6
m=0
the slope of the line is 0, which is option a
