Problem:
Craig earns extra money as a lifeguard. He earns $37 for 4 hours and $64.75 for 7 hours.
Answer:
The answer is: y = 9.25x
Step-by-step explanation:
Let the equation for the proportionality relation is y = mx .......... (1), where y represents the money that Craig earns for a duty of x hours.
Here, m is the constant of proportionality and we have to find its value.
Given that Craig earns $37 for 4 hours duty.
So, from equation (1), we have 37 = 4m, ⇒ m = 9.25
Therefore, the equation becomes y = 9.25x. (Answer)

a group of 8 friends go out to pizza. each person will buy a soda and 2 slices of pizza. Let s represent the cost of sodas and p represent the cost of pizza slices
Answer:
Step-by-step explanation:
If I'm not mistaken you're looking for an equation, if not then comment below...
y = 8s + 16p
Since there's 8 of them, they'll get 8 sodas total and 16 sliced of pizza total.
Water flows from a faucet at a constant rate. Kian
measures 8 cups of water in 6 seconds.
What is the constant of proportionality for the relationship of cups of water to minutes?
Answer:
4 cups every 3 second which means so 80 cuos in one minute
Step-by-step explanation:
hope this helps
The constant of proportionality for the relationship of cups of water to minutes is 80
Represent cups with c and time with t.
So, the given parameter can be represented using the following ratio
c : t = 8 : 6
Multiply by 10
c : t = 80 : 60
60 seconds = 1 minutes.
So, we have:
c : t = 80 : 1
Express as fractions
[tex]\mathbf{\frac ct = \frac{80}1}[/tex]
Multiply both sides by t
[tex]\mathbf{\frac ct = 80}[/tex]
Multiply both sides by 6
[tex]\mathbf{c = 80t}[/tex]
A proportional equation is represented as:
[tex]\mathbf{c= mt}[/tex]
Where m represents the constant of proportionality
By comparison:
[tex]\mathbf{m = 80}[/tex]
Hence, the constant of proportionality is 80

538 = ? hundred + ? tens + ? ones
What is the answer?
(I am doing this cause my friend won't stop saying that 8 is in the tens
Answer:
500 (or 5) is in the hundreds place, 30 (or 3) is in the tens place, and 8 is in the ones place.
Step-by-step explanation:
500 is five-hundred, 30 is a ten (10, 20, 30, 40...), and 8 is a one because it is a single digit number and no other numbers come before it, unless it is a decimal.
Tell whether the angles are complementary or supplementary. Then find the value of x
Answer:
Complementary, x=78
Step-by-step explanation:
90= (x-8)+20
complementary angles add up to 90 degrees.
Answer:
Complementary, x is 78
Step-by-step explanation:
Let's first define what complementary and supplementary angles are. Complementary angles add up to 90 degrees, and supplementary add up to 180. From this image, we can see that this is a right angle. Right angles add up to 90 degrees, therefore, this is a complementary angle.
Now, because we know that it is 90 degrees and that (x-8)+(20) = 90, then we can solve for x. However, if the angle is unknown, then we would do x-8=20. In this case, sense we know for sure this angle is complementary, we do
(x-8)+(20) = 90
X+12=90 We combined like terms
X=78 Inverse operations
You can plug 78 into x and check to see if it is correct if they are 90 degrees total.
If (he)={(0,1),(2,3),(-4,1)}, find h^-1(x)
The given function is
[tex]h(x) = \{ (0,1), (2,3), (-4, 1) \}[/tex]
The inverse function is
[tex]h^{-1}(x) = \{ (1,0), (3,2), (1,-4)\}[/tex]
To get the inverse, we swap each x and y coordinate.
The rule is [tex](x,y) \to (y,x)[/tex]
So that's why the point (0,1) becomes (1,0) for instance.
What integer values satisfy both inequalities?
−1 < x ≤ 2
−2 ≤ x < 3
Answer:
0, 1 and 2
Step-by-step explanation:
- 1 < x ≤ 2
has solutions x = 0, 1, 2
- 2 ≤ x < 3
has solutions x = - 2, - 1, 0, 1, 2
Thus the values of x that satisfy both are x = 0, 1, 2
Inequalities are used to represent unequal expressions.
The integer values satisfy both inequalities are 0, 1 and 2
The inequalities are given as:
[tex]\mathbf{-1 < x \le 2}[/tex] and [tex]\mathbf{-2 \le x < 3}[/tex]
First, we list out the elements of both inequalities
[tex]\mathbf{-1 < x \le 2}[/tex]
[tex]\mathbf{x = 0,1,2}[/tex]
[tex]\mathbf{-2 \le x < 3}[/tex]
[tex]\mathbf{x = -2 ,-1, 0, 1,2}[/tex]
0, 1 and 2 are common integers between both inequalities
Hence, the integer values satisfy both inequalities are 0, 1 and 2

There are 24 students in the class. They had the choice to buy supplies from two different stores, Store A and B. Each of them bought 2 binders and 5 notebooks. The students have a total of $420 to spend.
Answer:
Step-by-step explanation:
There's 24 students so I would do 5 × 24 which equals 120 so 420 - 120 is 300. Then 2 × 24 is 48. Now 300-48 is 252. They would have $252 left.

In a sixth grade class the ratio of boys to girls is 4:3 if there are 35 students in the class how many girls are there
Answer:
The given ratio is 3:4 this means there are 7 people in each unit of this ratio.
It is stated that there are 35 students in total . That would mean that there are
5 Total sets of students in this class . When we multiply the numbers in our starting ratio by this multiple of 5 , our ratio now becomes 15 : 20
15 and 20 do indeed add up to 35 … But , our question wants to know how many more GIRLS are in the class . Boys were calculated to be 15 in number .
Girls were calculated to be 20 in number .
We now know there were 5 more girls than boys in that class ..
5 is your answer .

total number of student in class=35
let the number of boys be 3x
let the number of girls be 4x
so therefore 3x+4x=35 =>7x=35 =>x=5
so therefore number of boys in class is 3x=>3(5)=15
and number of girls in class is 4x=>4(5)=20
so there are 20–15=5 more girls in class than boys.

Let the number boys in the class be b. So b/(35-b)=3:4, or 105-3b=4b, or 7b=105, or b=15. The number of girls in the class is 35-15=20 20-15=5
Ans: there are 5 more girls than the number of boys in the class.

Given that,
Triangle ABC is an isosceles right angle triangle.
In an isosceles triangle, two sides are equal and corresponding angles are equal.
Let the corresponding angles are α and α.
Since, one angle of right angle isosceles triangle is 90°.
Also, the sum of angles of triangle is 180°
Implies that,
α + α + 90 = 180
2α = 180 - 90

Sorry Guys, Angle 12 & 10 are effectively corresponding angles, but angle 10 & 7 are alternate interior angles. Anyways, Angle 12 & 10 are congruent and 10 & 7 are congruent. At the end, the three angles 12, 10, and 7 have the same measure. If we put it otherwise, the line B is intersecting line D which form right angles equals to 90 degrees, so angle 12 = 90, and the same happens with angle 10 and 7, so the three angles are congruent, but at the same time, angle 7 is supplementary with angle 12 because their sum is equal to 180, (90 + 90 = 180). If you think from different angles is hard to choose the right answer, so what I guess is that we don't need to take into account the angle 10, just the fact that line A intersect line C, and Line B intersect line D forming right angles, and that angle 7 and 12 are right angles which sum equals 180, therefore, we could say that they are supplementary angles, but also congruent because they measure the same, so at the end, I don't know what answer to choose. Both seems correct to me.
