Step-by-step explanation:
Given
[tex]Ratio=12:40[/tex]
Required
Determine the actual distance between x and y
The question is incomplete, as the scale distance between x and y is not given.
To solve this, we make assumptions.
A scale measurement is represented as:
[tex]Ratio = Scale : Actual[/tex]
So, we have:
[tex]Scale : Actual = 12 : 40[/tex]
Express as fraction
[tex]\frac{Actual}{Scale} = \frac{40}{12}[/tex]
Make Actual, the subject
[tex]Actual = \frac{40}{12} * Scale[/tex]
Now, assume that the distance between x and y is 60 (on the scale), the actual distance traveled will be:
[tex]Actual = \frac{40}{12} * 60[/tex]
[tex]Actual = 200[/tex]

Answer: y=2x
Step-by-step explanation:
Answer:
The second choice has the largest rate of change by 3
Step-by-step explanation:
you find the slopes of all of them.
# 1 has a slope of 2
# 2. [tex]\frac{y^{2}-y^{1} }{x^{2}-x^{1} }[/tex] = [tex]\frac{12 - 6}{3 - 1}[/tex] = [tex]\frac{6}{2}[/tex] = 3
# 3. has a slope of -5
# 4. [tex]\frac{y^{2}-y^{1} }{x^{2}-x^{1} }[/tex] = [tex]\frac{2.5 - 3}{1 - 0}[/tex] = [tex]\frac{-0.5}{1}[/tex]= -0.5

Matt is bringing 0.4 of a cake to school. What fraction of the cake is he bringing?
Answer:
2/5
Step-by-step explanation:
also=4/10
4/10
=2/5
Here, Matt is bringing 0.4 of cake.
For the denominator:
We are taking 1 for [.] decimal and take 0 for 4.
So, its fraction becomes 4/10=2/5 [if we divide both denominator and lobe by 2].

What is m∠1? Help me, please
Answer:
∠1 = 72°
Step-by-step explanation:
exterior ∠ = the sum of two opposite(remote) interior ∠s
∠1 = 37° + 35°
=> ∠1 = 72°
Answer:
72 degrees.
Step-by-step explanation:
Angle 1 is one of the triangle's exterior angles. The exterior angle theorem states that the measure of a triangle's exterior angle is equal to the sum of the opposite interior angles. Therefore, m<1 is equal to the sum of 35 and 37:
35+37=72
m<1 = 72 degrees

can someone j help me w this, ive reposted it twice now :-(((( due in an hour please help!:( will give brainliest
Step-by-step explanation:
I got you,
a) Work...
First equation: y = 4x + 3
Second equation: y = 2x + 11
If he wants to play 2 games...
y = 4 (2) + 3
y = 11
y = 2 (2) + 11
y = 15
Answer for part a: If a customer wants to rent shoes and play two games, they'll pay more with the new price plan. With the current price plan, they'll pay 11 dollars, but with the new price plan, they'll pay 15 dollars.
b) Work...
seven games...
y = 4 (7) + 3
y = 31
y = 2 (7) + 11
y = 25
Answer for part b: If the customer wants to play 7 games, including the shoes, they would pay less using the new plan. If the shes were not included, the new price will still be less. With the shoes, 7 games, with the original plan, is 31 dollars but 25 dollars with the new plan. If they didn't want to rent shoes, they would pay 28 dollars with the original plan but only 14 dollars with the new plan. All in all, they spend less on the new plan anyways.

Some students reported how many pairs of shoes they have. The dot plot shows the data collected: A dot plot is titled Students Pairs of Shoes and labeled Number of Pairs. The values on the horizontal line are 1, 2, 3, 4, and 5. There is 1 dot above 1, 3 dots above 2, 5 dots above 3, 3 dots above 4, and 1 dot above 5. What do the dots above the number 4 indicate? (3 points) a There are exactly 3 students with less than 4 pairs of shoes. b There are exactly 4 students with less than 3 pairs of shoes. c There are exactly 4 students with 3 pairs of shoes. d There are exactly 3 students with 4 pairs of shoes.
Answer:
There are exactly 3 students with 4 pairs of shoes.
Step-by-step explanation:
Given
[tex]Pairs \to Dots[/tex]
[tex]1 \to 1[/tex]
[tex]2 \to 3[/tex]
[tex]3 \to 5[/tex]
[tex]4 \to 3[/tex]
[tex]5 \to 1[/tex]
Required
What does the 3 on 4 represents?
First, we plot the dot plot.
See attachment for plot
The dots represent the number of student
So 3 dots on 4 means that:
[tex]Students \to 3[/tex]
[tex]Pairs \to 4[/tex]
This implies that there are 3 students have exactly 4 pairs
Answer:
D) There are exactly 3 students with 4 pairs of shoes.
Step-by-step explanation:
It says number of pairs on the bottom which means how many and 1, 2, 3, 4, 5 are the pairs of shoes.
At the top it says Students' pairs of shoes which is the dots and that means how many students have that amount.

Suppose you are going to draw two cards from a standard deck. What is the probability that the first card is an even card and the second card is Queen? 16/663 5/169 06/13 20/663
Answer:
I would say 16/663 but I still have a suspicion it may be 20/663
Step-by-step explanation:
Answer:
20/633
Step-by-step explanation:
The probability of drawing an even card is the total number of even cards divided by the total number of cards. There are 5 even values (2,4,6,8,10) and 4 of each in the deck. That means there are 20 even cards in a deck of 52 cards. The probability is 20/52.
Next, the probability of drawing a Queen is calculated, but now there are only 51 cards total because you removed the first card. There are 4 Queens in a deck of 51 cards. The probability is 4/51.
Therefore, the probability of these two events is the product of the probability of each: (20/52)(4/51) = 20/663
The population of a certain animal species decreases at a rate of 3% per year. You have counted 80 of the animals in the habitat you are studying. Write a function that models the change in the animal population.
A: f(x) = 80(3)^x
B: f(x) = 80(.03)^x
C: f(x) = 80(.97)^x
D: f(x) = 80(1.03)^x
Answer:
C. f(x) = 80(.97)^x
Step-by-step explanation:
If the population decreases by 3% each year, then it would be the same as multiplying it by 97% or 0.97 each year.
The function shown the the graph is f(x) =

pls help asap,,
Answer:
B
Step-by-step explanation:
We will first look at the end behavior of the graph
Is it down then up which means that the degree is 3 and the coeficcent is positive
this leaves B or C
We then know that the x intercepts are (-2,0) (1,0) (3,0)
The easiest way to proceed from here is just plugging in numbers into our euqation and if the end result is 0 then we got it!
looking at the B we have
-2³-2*-2²-5(-2)+6
this equals 0 which means this is our answer (this elimates C because the only difference between the two equations is the sign on the 5x)
You can also factor it and find the zeroes that way, but it's just more work
2. The dimensions of a rectangle can be given by x + 7 and x + 2. If the area of the rectangle is 66 square inches, what are the dimensions of the rectangle?
Answer:
(x+7)(x+2) = 66
x^2+9x+14=66
x^2 + 9x -52 = 0
(x+13)(x-4) = 0
x = 4 bc the other root, -13, can't be used (it would make the dimensions negative values)
