owen and needed to get his computer fixed he took it to the repair store the technician at the store worked on the computer for 5.5 hours and charged him $70 for parts the total is $702.50 what was the total cost of labor per hour
To figure out this problem, let's set up an equation first to make it easier:
702.50 = 5.5x + 70
x = amount charged per hour
702.50 = 5.5x + 70
-70 -70
-----------------------------
632.5 = 5.5x
/5.5 /5.5
--------------------
115 = x
Owen was charged $115 per hour

Mt. Boma is 8150 yards above sea level. There are 3 feet in a yard and 5280 feet in a mile, how many miles above sea level is Mt. Boma?
3.1 miles
46 miles
31 miles
1.5 miles
4.6 miles
15 miles
Answer:
4.6
Step-by-step explanation:
8,150 x 3 = 24,450 so
8,150 yards = 24,450 feet
and 24,450 divided by 5,280 = ~4.63
so 24,450 feet = 4.6 miles

Answer: h(35) = 43
Step-by-step explanation: The question is asking you to solve the equation if t = 35:
h(t) = 50 - t/5
h(35) = 50 - 35/5 <— I substituted 35 in for t.
h(35) = 50 - 7
h(35) = 43
Answer:
The answer is 43
Step-by-step explanation:
[tex]h(t) = 50 - \frac{t}{5}[/tex]
[tex]h(35) = 50 - \frac{35}{5}[/tex]
[tex]h(35) = 50 - 7[/tex]
[tex]h(35)=43[/tex]

alan is spreading fertilizer on a field to get it ready for planting. The directions say to use 4/5 of a quart of fertilizer for each acre of land. Alan has two fields, one that is 22 1/2 and one that is 38 1/4. How much total fertilizer will Alan need for his two fields?
Answer:
48.6 quart of fertilizer
Step-by-step explanation:
The directions say to use 4/5 of a quart of fertilizer for each acre of land.
Alan has two fields,
Field 1
22 1/2 acre of land
1 acre of land = 4/5 quart
22 1/2 acre of land = x
Cross Multiply
x = 22 1/2 × 4/5
x = 45/2 × 4/5
x = 18 quart of fertilizer
Field 2
38 1/4 acres of land
1 acre of land = 4/5 quart
38 1/4 acre of land = x
Cross Multiply
x = 38 1/4 × 4/5
x = 153/4 × 4/5
x = 30.6 quart of fertilizer
The total fertilizer that Alan will need for his two fields is calculated as:
18 quart of fertilizer + 30.6 quart of fertilizer
= 48.6 quart of fertilizer

a system of inequality, where x is the rate of a spaceship in a video game and y is where the ship travels on the screen in 3.5 seconds, is represented by the graph. which symbol could be written in both circles in order to represent this system algebraically?
Answer: B. >=
Step-by-step explanation: Sorry if I'm late, but here's proof. If you see that both the lines intersect and split ways at -6 x-int on the graphing calculator, its the same graph. So the answer would be >=.
:)
The system of inequality is solved and 3 ≤ x ≤ 5
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
y ≤ (7/4)x + (17/2) (left circle)
y ≥ (7/4)x + (17/2) (right circle)
So, we can write the system of inequalities algebraically as:
3 ≤ x ≤ 5
(7/4)x + (17/2) ≤ y ≤ (7/4)x + (17/2)
The correct symbol to write in both circles in order to represent this system algebraically is "≤" (less than or equal to)

what is 16/20 minus 1/4 in simpilest forrm
Answer:
11/20
Step-by-step explanation:
16/20 - 1/4
rewrite 1/4 with same denominator (multiply by 5)
16/20 - 5/20 = 11/20
Is this correct or no
Answer:
Incorrect
Step-by-step explanation:
The correct answer is A.
The slope-intercept form is y-y₁=m(x-x₁)
The problem with B is that if you take out the coordinates for x₁ and y₁, you get the coordinates (1,4). This coordinate does not land on the line.
The coordinates for A is (-1,4). This point does land on the line.

Write an equation in point-slope form of the line that passes through (-4,1) and (4,3).
Answer:
An equation in point-slope form of the line that passes through (-4,1) and (4,3) will be:
[tex]y-1=\frac{1}{4}\left(x+4\right)[/tex]
Step-by-step explanation:
Given the points
(-4,1)(4,3)Finding the slope between the points (-4,1) and (4,3)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-4,\:1\right),\:\left(x_2,\:y_2\right)=\left(4,\:3\right)[/tex]
[tex]m=\frac{3-1}{4-\left(-4\right)}[/tex]
Refine
[tex]m=\frac{1}{4}[/tex]
Point slope form:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointin our case,
m = 1/4(x₁, y₁) = (-4,1)substituting the values m = 1/4 and the point (-4,1) in the point slope form of line equation.
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-1=\frac{1}{4}\left(x-\left(-4\right)\right)[/tex]
[tex]y-1=\frac{1}{4}\left(x+4\right)[/tex]
Thus, an equation in point-slope form of the line that passes through (-4,1) and (4,3) will be:
[tex]y-1=\frac{1}{4}\left(x+4\right)[/tex]

Answer: 11.375°
Step-by-step explanation:
55 + (4x + 17) + (4x + 17) = 180° Set up equation
4x + 4x + 55 + 17 + 17 = 180° Commutative Property of Addition
8x + 89 = 180° Combine like terms
8x = 91° Subtract 89 from both sides
x = 11.375° Divide both sides by 8

Answer:
y=-3.5x-9.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
so we use the equation y2-y1=m(x2-x1)
let's say (-3,1) is point 1 and (-5,8) is point 2
we plug in what we know
8-1=m(-5-(-3))
subtracting a negative is the same as adding so -5 - (-3) = -2
7=-2m
divide both sides by -2
-7/2=m
-3.5=m
so slope intercept form is y=mx+b
we know the slope (m) but we still need the "b" which is the y-intercept.
so you pick whichever point you want (I'm going to chose point 1 but it doesn't matter) and plug it in
1=-3.5(-3)+b
1=10.5+b
-9.5=b
so the equation would be y=-3.5x-9.5

Answer:
-8,-6
Step-by-step explanation:
The completed table for y = 2x - 4 is ( - 2, 0), (- 1, - 6), and (0, -4)
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A function y = 2x - 4.
Now at x = - 2 we'll simply put the numerical value of x in y.
y = 2(2) - 4.
y = 4 - 4.
y = 0.
( - 2, 0).
At x = - 1.
y = 2(-1) - 4.
y = - 2 - 4.
y = - 6.
(- 1, - 6).
At x = 0.
y = 2(0) - 4.
y = 0 -4.
y = -4.
(0, -4)

Find the area of the
regular figure below:
A) 67.3 in2
B) 70.2 in2
C) 74.6 in2
D) 77.1 in 2
E) 82.8 in2
pls show work
Answer:
Option E
Step-by-step explanation:
Central angles of a regular polygon = [tex]\frac{360}{n}[/tex]
Here, n = Number of sides of the regular polygon
Therefore, central angle of the regular polygon = [tex]\frac{360}{8}[/tex] = 45°
From the picture attached,
m∠AOB = [tex]\frac{45}{2}[/tex] = 22.5°
By tangent rule,
tan(∠AOB) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(22.5°) = [tex]\frac{AB}{OB}[/tex]
AB = OB[tan(22.5°)]
AB = 5(0.414213)
= 2.07 in
Therefore, area of ΔAOC = 2 × (Area of ΔABO)
= [tex]2(\frac{1}{2})(\text{Base})(\text{Height})[/tex]
= AB × OB
= 2.07 × 5
= 10.35 in²
Since, area of the given regular octagon = 8 × (Area of ΔAOC)
= 8(10.35)
= 82.5 in²
Therefore, Option (E) is the answer.
