You earn $320 in 40 hours. At this rate how many hours do you work to earn $440?
Answer:
60.5
Step-by-step explanation:
320/44=7.27
440/7.27=60.5
Answer: 55 Hours
Step-by-step explanation:
If you take 320 and divide it by 40
you get 8
This means you earn $8 for every hour you work.
Now if you take 440 and divide it by 8, meaning $440 dollars divided by $8
You will get
55, meaning you must work 55 Hours to make $440.

Which table represents a quadratic function?
Answer:
D
Step-by-step explanation:
A table of values can be generated from a quadratic function by substituting the x-values and calculating the values for f(x). When looking at a table of values for a quadratic function, the x-intercepts represent the x-values where y = 0. This corresponds to the x-values where f(x) is 0 in function notation.

pls help trigonometry is confusing to me :(
My first tip would be to label your triangles.
If you find our reference angle and go across, that would be our opposite side, so x is the opposite side.
The line with both the reference angle and the right angle would be our adjacent side, so 40 would be the adjecent side.
If you find the right angle and go across, that would be our hypotenuse.
//
In this problem, we are given an angle and the adjacent side and we are looking for the opposite side, so that means that we would be using our tangent ratio.
[tex]tan = \frac{opp}{adj} = \frac{x}{40} [/tex]
[tex] \tan(43) = \frac{x}{40} [/tex]
if the thing you are looking for is on the numerator, we would have to multiply. If the thing you're looking for is in the denominator, you would have to divide.
Since x is on the numerator, we would have to multiply.
[tex]x = 40 \tan(43 ) [/tex]
[tex]x = 37.3006034455[/tex]
[tex]x = 37.30[/tex]

Complete the statements about the system of linear equations represented by the tables.
The equation representing the left table is
.
The equation representing the right table is
.
The solution to the system of equations is
Answer:
The equation representing the left table is:
y = 1.5x – 6
The equation representing the right table is:
y = –4x + 6.1
The solution to the system of equations is:
(2.2, –2.7)
Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The first table is
x y
0 -6
1 -4.5
2 -3
3 -1.5
Slope = -4.5+6/1
=1.5
Now let us find y intercept
-6=1.5(0)+b
-6=b
So the equation representing the left table is y=1.5x-6
Now let us find second table
x y
0 6.1
1 2.1
2 -1.9
3 -5.9
m=2.1-6.1/1=-4
Now y intercept
2.1=-4+b
b=2.1+4
b=6.1
Equation representing the right table is y=-4x+6.1
Now equate two equations
1.5x-6=-4x+6.1
1.5x+4x=6.1+6
5.5x=12.1
x=12.1/5.5
x=2.2
and y=-4(2.2)+6.1
y=-8.8+6.1
y=-2.7
Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

The table shows data for a car stopping on a wet road. Stopping distance formula [tex]d(v)=\frac{2.15v^{2} }{64.4f}[/tex]
Determine the value of f, rounded to the nearest hundredth.
Answer:
0.35
the next one is d(v) = 2.15v^2 / 22.54
Step-by-step explanation:
i just did this assignment. also thanks to the answer above me :)
We have that the value of f, rounded to the nearest hundredth.
f_1=0.02
f_2=0.009
f_3=0.009
From the question we are told that
d(v)= \frac{2.15v^2}{64.4f}
Generally the equation for the f is mathematically given as
f= \frac{2.15v^2}{64.4*d(v)}
Therefore
For v=20 and f=38
f= \frac{2.15(20)^2}{64.4*(38)(20)}
f=0.02
For v=30 and f=86
f=\frac{2.15(30)^2}{64.4*(86)(30)}
f=0.01
For v=40 and f=153
f=\frac{2.15(40)^2}{64.4*(153)(40)}
f=0.009

Leigh-Anne invests £2500 for 4 years in a savings account.
She gets 3% per annum compound interest.
How much money does Leigh-Anne have at the end of 4 years.
Answer:
After 4 years, Leigh-Anne will have £ 2,813.77 in her account.
Step-by-step explanation:
Given that Leigh-Anne invests £ 2500 for 4 years in a savings account, and she gets 3% per annum compound interest, to determine how much money does Leigh-Anne have at the end of 4 years, the following calculation must be performed:
X = 2,500 x (1 + 0.03 / 1) ^ 4
X = (2,500 x 1,003) ^ 4
X = 2,813.77
Thus, after 4 years, Leigh-Anne will have £ 2,813.77 in her account.
HELPPPPPPP pleaseeeeee it's a test!!!
Answer:
-18, -12, 0, 25, 5
0, -12, 5, -18, 25
25, 0, -18, 5, -12
-12, 25, 5, 0, -18
5, -18, 25, -12, 0
Step-by-step explanation:
The only values you need to use here are 0, 5, 25, -12, and -18.
I started with the bottom right box because the far right column only had one empty box. From the set of values I stated above, that column already had each of those numbers except for 0, so 0 would go in the bottom right box.
Another way to think about it is each row or column must have a 5 and a 25 to make 30, and a -12 and a -18 to make -30. Those two numbers cancel each other out to make 0, and then each row/column will include a 0 value which obviously wouldn't effect that balance. So the whole row/column will come out to be 0.
After figuring out that first bottom right box, go to the next row/column with only one empty box left (this happened to be the very bottom row), and use the same strategy to fill in the missing value.
Continue finding the next row/column with only one empty box left and figure out its missing value until you've completed the whole box.
Write the equation of the line in slope-intercept form with slope = 1/4 and point (-8, 6)
Step-by-step explanation:
This is the standard linear equation:
[tex]y=mx+b[/tex]
[tex]m[/tex] represents slope and [tex]b[/tex] represents the y-intercept. In a finished equation, [tex]x[/tex] and [tex]y[/tex] are left as variables. [tex]x[/tex] and [tex]y[/tex] represent any given point in the function. In this case, one of the given coordinates is [tex](-8, 6)[/tex], and we can use this by using [tex]-8[/tex] as [tex]x[/tex] and [tex]6[/tex] as [tex]y[/tex]. After plugging in known variable, the equation becomes this:
[tex]6 = \frac{1}{4} ( - 8) + b[/tex]
This simplifies to:
[tex]6 = - 2 + b[/tex]
Then to:
[tex]4=b[/tex].
After plugging in slope and y-intercept, the finished equation is:
[tex]y = \frac{1}{4} x + 4[/tex]
