Answer:
n = 185/9
Step-by-step explanation:
(6n-25) + (3n + 20) = 180
Combine like terms
9n -5 = 180
Add 5 to each side
9n - 5 +5 = 180+5
9n = 185
Divide each side by 9
9n/9 = 185/9
n = 185/9

A guitar is originally priced at $80. The online retailer gives a discount and the guitar is now priced at $44. Enter the percentage discount for the cost of the guitar. (PLEASE ANSWER THIS I NEED THE ANSWER BY TODAY RIGHT NOW!!!)
Answer:
The percentage discount for the cost of the guitar is 45%.
Step-by-step explanation:
First let's find the difference between the original price and the new price.
80 - 44 = 36
So the actual discount got the price down by $36.
To find the percentage discount we need to ask ourselves the question
36 is what percent of 80?
36 = X percent of 80
In math, of means multiply.
36 = X percent * 80
So to get the "X percent" part alone we divide by 80 on both sides.
36 divided by 80 = 0.45
36 is 45 percent of 80.
The percentage discount for the cost of the guitar is 45%.

Find the slope of a line through (4, 5) and (4, -5). Determine if the line is vertical, horizontal, or neither.
Answer:
Vertical
Slope cannot be determined
Step-by-step explanation:
To find the slope, we are going to use the slope equation as follows
m = (y2-y1)/(x2-x1)
(x1,y1) = (4,5)
(x2,y2) = (4,-5)
m = (-5-5)/(4-4)
This gives an undefined answer and thus we cannot hate the slope value
Looking at the x-axis coordinates, we can see that the difference is just the y axis coordinates and as such we can confirm that the line is vertical

Answer:
B: 112.5
Step-by-step explanation:
first, we split up the rhombus into two triangles, with the height of 15 and the length of 7.5. when you multiply these you will get 112.5, and normally if you are just getting the area of the triangle, then you would divide it by two, but seeing that we have 2 triangles here, we would multiply it by two afterwards so an easier way to do it is just to not divide.
If the equation y=-5x+12 is translated up five units, what would the new equation be?
Answer:
y=-5x+17
Step-by-step explanation:
Answer:
[see below]
Step-by-step explanation:
We would add '5' to the y-intercept (12) to make a translation up 5 units.
y = -5x + 12 + 5
y = -5x + 17

The circumference of a circle is 8.34cm. Find the length of the diameter. Give your answer rounded to 2 DP.
Answer:
Diameter, D = 2.65 cm
Step-by-step explanation:
Given the following data;
Circumference of circle = 8.34 cm
To find the length of its diameter;
Mathematically, circumference of a circle is equal to;
C = πD
Where;
C is the circumference of a circle.D is the diameter of a circle.Pie, π = 3.142Substituting into the formula, we have;
8.34 = 3.142 * D
[tex] D = \frac {8.34}{3.142} [/tex]
Diameter, D = 2.65 cm

If f(x) = \XI + 9 and g(x) = -6, which describes the range of (f + g)(x)?
O (f + g)(x) > 3 for all values of x
O (f + g)(x) < 3 for all values of x
O (f + g)(x) < 6 for all values of x
O (f + g)(x) > 6 for all values of x
Answer:
the first option
Step-by-step explanation:
well, 9 +(-6) = 3
so the equations last part is changed, but the rest stays the same
The range of (f + g)(x) is (f + g)(x) > 3 for all values of x.
What is a function?A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Gives are two function, f(x) = |XI + 9 and g(x) = -6, we need to find the range of (f + g)(x),
f(x)=|x|+9 and g(x)= -6
Taking the sum of the functions:
f(x) + g(x) = |x|+9 + (-6)
f(x) + g(x) = |x|+9 - 6
f(x) + g(x) = |x|+3
Due to the modulus of x which is positive,
Hence (f + g)(x) is greater to 3 for all values of x

A salesman is paid $450 a week, plus a commission of 35 cents for every item that he sells. Write a linear function where the paycheck, P, of the salesman is a function of the number, N, of items he sells. If the salesman only has 1400 items available to sell each week, find the domain and range of the function.
Answer:
Step-by-step explanation:
1400×0.35
490+450
940
Answer:
The domain is thus [0, 1400].
The range is thus [$450, $940]
Step-by-step explanation:
A suitable function is P(N) = ($450) + ($0.35 / item)*N, where $450 is the base pay per week and N is the number of items sold.
In this case the salesman has only 1400 items available to sell each week. Therefore N begins at 0 (no items to sell) and ends at 1400 (the max number of items available to sell). The domain is thus [0, 1400].
The smallest amount the salesman could receive would be when he has not sold any items: $450.
The max amount is then $450 + ($0.35/item)(1400 items), or
$450 + $490, or
$940
The range is thus [$450, $940]
angle H and angle D are supplementary. If angle H has a measure of 128 degrees, find the measure of angle D
m<H + m< D = 180°
Since m<H and m<D are supplementary angles.
128°+m<D =180°
m<D = 180-128
m<D = 52°
Answer: m<D = 52°
Answer:
angle D=52 degree
Step-by-step explanation:
In supplementrary angles sum of two angles is always 180 degree
angle H +angle D=180 degree (since they are supplementary angles)
sbstitute the value of H
128 + angle D=180
angle D=180-128
angle D=52 degree
therefore angle D is 52 degree.

Ophelia spins each of the three shown spinners once. What is the probability that the first spinner will land on A, the second on 4, and the third on Green? Enter your answer as a fraction in simplest form. Use / to write your fraction.
Answer:
1 /24
Step-by-step explanation:
Given the 3 spinners :
Probability = required outcome / Total possible outcomes
Probability that Spinner 1 lands on A :
P(spinner 1 lands on A) = 1/2
Probability that spinner 2 lands on 4 :
P(lands on 4) = 1 / 4
Probability that spinner 3 lands on green :
P(lands on green) = 1/3
Combined probability = 1/2 * 1/4 * 1/3 = 1 /24
7th grade girl!
*(urgent, please help! )*
For all the angles, you will have to solve for x
A: 162 = 3x
162/3 = x
54 = x
M: 120 + 2x = 180
2x = 180 - 120
2x = 60
x = 60/2
x = 30
W: 150 = 30x
150/30 = x
5 = x
S: 20 + 2x = 90
2x = 90 - 20
x = 70/2
x = 35
Q : 45 + 5x = 90
5x = 90 - 45
x = 45/5
x = 9
P: not too sure if its 150,
150 + (x+5) = 180
x+5 = 180- 150
x = 30 - 5
x = 25
now you will put all the x values in order. ( i think thats what you supposed to do)
it will be: 5, 9, 25, 30, 35, 54

height, H = 6 ft
The area of walls is
= 2 (L W + W H + H L)
= 2 (30 x 50 + 50 x 6 + 6 x 30)
= 2 (1500 + 300 + 180)
= 3960 square feet
