Answer:
9x + 22y ≥ 220
x + y ≤ 16
Step-by-step explanation:
First x is number of hours washing cars and y is number of hours tutoring.
He makes $9 per hour on cars, $22 per hour tutoring. So we use variables as substitutes for actual values.
That is 9x + 22y. He can't make less than 220, so use the sign greater or equal to 220.
He also must work no more than 16 hours. Total hours is x+y, and no more than 16 means use the sign less than or equal to.

The number of hours washing cars and number of hours tutoring, if Blake is working two summer jobs, making $9 per hour washing cars, making $22 per hour tutoring, are 10.2 and 5.85 respectively. The graph is also attached below.
What is equation?A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation. As in, 3x + 5 Equals 15, instances.
Given:
Blake is working two summer jobs, making $9 per hour washing cars, making $22 per hour tutoring,
Total working hour = 16
Total money to be earned = $220
Write the equation of the above statement as shown below,
x + y = 16
9x + 22y = 220
Solve the above equation using a graph,
y = 5.85 and x = 16 - 5.85 = 10.2

Answer:
Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Todhunter (1888) who wrote it as "y = mx + c".

jake earned 30 points out of a total of 43 on his most recent math test. on his social studies test, jake scored 85 out of a possible 124 points.
on evict rest did jake score a higher percentage of the total? just your answer.
Answer: See explanation
Step-by-step explanation:
Your question isn't really clear but let me help.
For Maths test,
Point earned = 30
Total point = 43
Percentage = 30/43 × 100 = 69.77%
Social studies test
Point earned = 85.
Total point = 124
Percentage = 85/124 × 100 = 68.55%
From the above, we can see that Jake scored a higher percentage in the Maths test.

Step-by-step explanation:
We can change the km to m first. 1km = 1000m.
84km/h = 84 000m/h
Then, we can change the h to s. 1h = 3600s.

If the temperature outside increases by 3 1/2 degrees every 1 1/2 hours, by how much will the temperature increase after 4 hours?
please answer in fractions.
Part 1:
What is the rate per hour of the temperature increase?
Part 2:
How much will the temperature increase after 4 hours?
Answer:
2 1/3 ; 9 1/3
Step-by-step explanation:
Given that:
Outside temperature increases by 3 1/2 degrees every 1 1/2 hours
The rate per hour of temperature increase will be :
Let rate per hour = x
3 1/2 = 1 1/2
x = 1
Cross multiply :
1 1/2 * x = 3 1/2 * 1
3x/2= 7/2
Multiply both sides by 2/3
3x/2 * 2/3 = 7/2 * 2/3
x = 14/ 6
x = 2 2/6
x = 2 1/3
Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.
2.) Temperature increase after 4 hours :
(Temperature rate per hour * number of hours)
(2 1/3) * 4
(7/3) * 4
28 / 3
= 9 1/3
Hence, temperature increase after 4 hours = 9 1/3
2 1/3 ; 9 1/3
Step-by-step explanation:
Given that:
Outside temperature increases by 3 1/2 degrees every 1 1/2 hours
The rate per hour of temperature increase will be :
Let rate per hour = x
3 1/2 = 1 1/2
x = 1
Cross multiply :
1 1/2 * x = 3 1/2 * 1
3x/2= 7/2
Multiply both sides by 2/3
3x/2 * 2/3 = 7/2 * 2/3
x = 14/ 6
x = 2 2/6
x = 2 1/3
Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.
2.) Temperature increase after 4 hours :
(Temperature rate per hour * number of hours)
(2 1/3) * 4
(7/3) * 4
28 / 3
= 9 1/3
Hence, temperature increase after 4 hours = 9 1/3

A statue that is 80 m tall stands on a 625 m2 base. An artist creates a replica using a ratio of 1:15. What is the area of the replica's base?
Answer: [tex]2.78m^{2}[/tex]
Step-by-step explanation:
given data:
height of the statue = 80m.
base of the statue = [tex]625m^{2}[/tex].
scale of the statue replica = 1:15.
solution:
[tex]= 1:15^{2} \\\\\= 1:225\\\\[/tex]
[tex]= \frac{625m^{2} }{225}[/tex]
= [tex]2.78m^{2}[/tex]
the area of the replica is [tex]2.78m^{2}[/tex]
Answer:
2.78 m^2 is the correct answer. :)

F a person is earning $34,923 per year, approximately how much should they be saving, including retirement and other savings?'
Answer:
$6,984.60 per year.
Step-by-step explanation:
Using a normal and very common budget, you should divide your monthly/annual salary into 3 main tiers, which are the following
50% = necessities (rent, food, bills, etc)30% = lifestyle choices (clothes, entertainment, hobbies, etc)20% = savings (retirement, emergency fund, etc.)If we go by this budget then we would need to turn the 20% into a decimal by dividing it by 100 and then multiply that decimal by the person's annual salary.
20% / 100 = 0.20
$34,923 * 0.20 = $6,984.60
Finally, we can see that the individual should be saving roughly $6,984.60 per year.

Answer:
A
Step-by-step explanation:
edge
The polar form of z is 6√2(cos(135°) + isin(135°)).
What Is Polar Form of Complex Numbers?Complex numbers are represented in polar form as the complex number's modulus r and argument combined. Given as z = r cosθ + i r sinθ = r (cosθ + i sinθ). the polar form of the complex number z = x + iy with coordinates (x, y) is given. Polar coordinates of real and imaginary numbers in the coordinate system are used to express the polar form. A complex number in a two-dimensional coordinate system is A = x + i y
Given the point z
From the positive real axis, the angle to the point in the second quadrant is calculated (the x-axis). The only options that make sense for the second quadrant are the 135° angles, which fall between 90° and 180°.
The square root of the sum of the squares of z's components determines its magnitude:
|z| = [tex]\sqrt{x^{2} + y^{2} }[/tex]
here x = -6 and y = 6
|z| = √(-6²) + (6²)
z = 6√2
polar form is
z = 6√2(cos(135°) + isin(135°))
Hence the complex form is 6√2(cos(135°) + isin(135°)).

grid. I asked him to use patches of red, blue,
green and yellow, but to ensure that no patch
touches another of the same colour, not even di-
agonally.
The picture shows an attempt which fails only
because two yellow patches touch diagonally.
In how many different ways can my grandson

Answer:
168
Step-by-step explanation:
Below are shown the 7 different kinds of arrangements that can be made. Each of these can be permuted into 24 different arrangements by assigning colors in a different order than the one used here:
{1, 2, 3, 4} ⇒ {green, blue, red, yellow}
Then the total number of possible correct colorings is 7·24 = 168.
__
These colorings were found using a computer program that identified all 168 viable colorings, then eliminated permutations. It started by identifying ways to color 2 rows, then adding rows based on that.

The 8th Grade wants to raise money for a field trip that costs $800. 15 students are in charge of fundraising. What is the minimum amount of money they each have to raise to achieve their goals (if they each raise the same amount of money)?
Answer: $54.35
Step-by-step explanation:
If each one of the 15 students raises the same amount, let's define this amount by the variable X, then the total amount they will collect is 15 times X, or:
15*X
And the minimum amount they need to collect is $800
Then we will have the inequality:
15*X ≥ $800
Now we can divide both sides by 15 to get the minimum amount that each student needs to raise:
(15*X)/15 ≥ $800/15
X ≥ $54.33...
Where we should round up the right number to $54.35, because we can not have a $0.0333... and if we round down, they would collect less than $800.
Then the inequality is:
X ≥ $54.35
This means that the minimum amount that each one of the 15 students needs to collect is $54.35
