Using the concept of proportionality, it is found that these following situations represent proportionality:
A) The total amount a babysitter makes who earns $10 an hour for babysitting r hours.
C) The total amount Andrew saves when he saves $24 a week for w weeks.
In a proportional relationship, the output y is given by the input x multiplied by a constant k, that is:
[tex]y = kx[/tex].
Thus, when x = 0, y = 0.In this problem:
In options A and C, when the input is 0, the output is also 0, thus they are proportional.In option B, when the input is 0 days, the output is 5 inches of snow, thus it is not proportional.In option D, when the input is of 0 months, the height is of 7 inches, thus also not proportional.A similar problem is given at https://brainly.com/question/22846068

3 to the power of 4 divided by 3 to the power of 9 all simplified expressions
Answer:243
Step-by-step explanation:
The simplified value of [tex]3^4[/tex]/[tex]3^9[/tex] is 1/ [tex]3^5[/tex].
what are exponents and power?Exponent rules, commonly referred to as the "laws of exponents" or "properties of exponents," facilitate the task of simplifying exponent-based statements.
Some laws are
[tex]a^0= 1[/tex][tex]a^m . a^n = a^{m+n[/tex][tex]a^m/ a^n = a^{m-n}[/tex]Given:
3 to the power of 4 divided by 3 to the power of 9
Writing into expression
[tex]3^4[/tex]/[tex]3^9[/tex]
Now, using law of exponents
[tex]a^m/ a^n = a^{m-n}[/tex]
So, [tex]3^4[/tex]/[tex]3^9[/tex]
=[tex]3^{4-9}[/tex]
= [tex]3^{-5[/tex]
=1/ [tex]3^5[/tex]
Hence, the simplified value is 1/ [tex]3^5[/tex].

A small order of fries at Wendy’s has 90 more calories than the small order of fries at McDonald’s. If together they have 550 calories, how many calories are in the Wendy’s small order of fries?
Answer:
320 caloriesStep-by-step explanation:
Small order of fries at Wendy’s = x calories
Small order of fries at McDonald’s = y calories
x = y + 90x + y = 550Substitute x in the second equation
y + 90 + y = 5502y = 550 - 902y = 460y = 230Then, x is:
x = 230 + 90 = 320 caloriesplease helppp!!!!!!!

You start at (5, -5). You move up 4 units and down 2 units. Where do you end?
Answer:
(5, -3)
Step-by-step explanation:
if you move up four units and then down two, you're only moving up 2 units
the -5 is the y (up/down) value, so you add two to it, ending up with (5, -3)

Is the relationship for Camille’s puppies weight in terms of linear or nonlinear
Answer:
linear
Step-by-step explanation:
Where is the picture for this problem???
Answer:
Camille's is linear
Step-by-step explanation:
The weight for Camille's puppy increases in a constant rate(the puppy gains .5 pound per week, every week).
Amit's puppy is non-linear. Observe the table
X 1 2 3 4 5 6 7 8 9 10
Y 4 6 8 12 16 20 22 24 28 32
weeks start out with constant + 2 changes, then at week 3-4 the puppy gains a +4 (no longer linear - your line is no longer straight)

Finley and Cooper are wanting to go to SkyZone. Finley pays $53.75 for 5 hours. How much will Cooper pay for 3 hours?
Answer:
10.75 x 3 = $32.25
Step-by-step explanation:
first, we need to figure out how much the cost is for one hour:
53.75/5 = 10.75
therefore, the cost at skyzone for 1 hour is $10.75 , BUT, we still need to figure out the time for 3 hours.
so, 10.75 x 3 = $32.25
Answer: 32.25

Use the figure to find the measure of
the angle. Explain your reasoning.
1. ∠4
2. ∠5
3. ∠8
4. ∠6
Answer:
1. ∠4 = 152°
2. ∠5 = 152°
3. ∠8 = 152°
4. ∠6 = 28°
Step-by-step explanation:
1. ∠4 and 152° are vertical angles. Therefore, m∠4 = 152°.
2. ∠5 and 152° are corresponding angles. Therefore, m∠5 = 152°
3. ∠8 and 152° are alternate exterior angles, therefore, m∠8 = 152°
4. ∠6 and <8 are a linear pair. Therefore,
m∠6 + m∠8 = 180°
m∠6 = 180° - m∠8
m∠6 = 180° - 152°
m∠6 = 28°
