Elena babysits her neighbors children. her earnings are given by the equation y=8.40x, where x represents the number of hours she worked and y represents the amount of money she earned. Jada earns 7$ per hour mowing her neighbors lawn.
question: How much money does Jada make after working 5 hours?
ANSWER FAST PLEASEE.
Answer:
she makes 10$ an hour
Step-by-step explanation:
Jada makes 35$ after working for 5 hours.
What is the ratio?We may determine how much of one quantity is in the other by comparing two amounts of the same units and finding the ratio.
Given, Jada earns 7$ per hour mowing her neighbor's lawn. remaining data is unnecessary for the given problem.
working 1 hour Jada makes = 7
working 5 hours Jada makes = 7* 5 = 35
Therefore, $35 is money Jada makes after mowing her neighbor's lawn.

Step-by-step explanation:
Step 1: Define
6 + 18r = 20r - 18 - 4r
Step 2: Solve for r
Combine like terms: 18r + 6 = 16r - 18Subtract 16r on both sides: 2r + 6 = -18Isolate r term: 2r = -24Isolate r: r = -12The visitors at a carnival can play two different games for a chance to win tickets to put towards a prize. Game A costs two tokens to play and the probability of winning a ticket isGame B costs three 1/3 tokens to play and the probability of winning a ticket is Which of the following strategies is most 1/2 likely to result in a person getting the most tickets?
Answer:
B
Step-by-step explanation:
Both games have the same probability so it does not matter which one you choose. Game A gives a ticket 1/3 of the time and costs two tokens to play so you need 6 tokens to win a ticket. Game B gives a ticket 1/2 and costs three tickets to play so you also need 6 tokens to win a ticket.

11. The price of a new
pair of True Religion
jeans is marked down
from $159.99 to $39.99.
What percentage was
taken off?
Answer:
The percentage which was taken off = 75%
Step-by-step explanation:
Initial value = $159.99Final value = $39.99Using the formula
Percentage Decrease = [ (Initial Value - Final Value) / |Initial Value| ] × 100
= [(159.99 - 39.99) / (159.99)] × 100
= [120 / 159.99] × 100
= 0.75 × 100
= 75%
Therefore, the percentage which was taken off = 75%
Matt has 4 deciliters of milk . Will the milk fill a 1-litre bottle
Answer:
no
Step-by-step explanation:
because 1 deciliters is 0.1 liters
The 4 deciliter milk will not fill a 1 litre bottle
How to determine the milk quantity?From the question, the amount of milk is:
Amount = 4 deciliters
As a general rule;
1 deciliter = 0.1 liters
So, we have:
Amount = 4 * 0.1 liters
Evaluate the product
Amount = 0.4 liters
0.4 is less than 1
Hence, the milk will not fill a 1 litre bottle

The equation modeling the population growth of a small town is P(t)=30000(1.02)^t, where P represents the population, and t represents the years from now. What is the approximate population change that occurs between 2 years from now and 10 years from now.
a.5,358
b.6,570
c.31,212
d.35,150
e.36,570
Answer: I’m not for sure but I got 31,212
Step-by-step explanation: You multiply 30000 to 1.02 and then with the 2 and the 10 you divided and get 31,212
The population change between these years is (a) 5358
The population model is given as:
[tex]\mathbf{P(t) = 30000(1.02)^t}[/tex]
When t = 2, we have:
[tex]\mathbf{P(2) = 30000(1.02)^2}[/tex]
[tex]\mathbf{P(2) = 31212}[/tex]
When t = 10, we have:
[tex]\mathbf{P(10) = 30000(1.02)^{10}}[/tex]
[tex]\mathbf{P(10) = 36570}[/tex]
The population change is then calculated as:
[tex]\mathbf{\Delta P = P(10) - P(2)}[/tex]
So, we have:
[tex]\mathbf{\Delta P = 36570 - 31212}[/tex]
[tex]\mathbf{\Delta P = 5358}[/tex]
Hence, the population change between these years is (a) 5358

Farhan cycles the first part of a 150-km journey at an average speed of 35km/h and walks the
remaining distance at an average speed of 5 km/h. if he takes 4.5 hours for his entire journey, find the
distance by he cycles.
Answer:
PLEASE MARK AS BRAINLIEST
Step-by-step explanation:
5 x 4.5 = 22.5 (km)
150 – 22.5 = 127.5 (km)
35 – 5 = 30 (km/h)
127.5/30 = 4.25 (h)
4.25 x 35 = 148.75 (km)
Alternatively,
Let x be the distance that he cycles.
x/35 + (150 – x)/5 = 4.5
x + 1050 – 7x = 157.5
6x = 892.5
x = 148.75
Ans : 148.75km.

The answer here is option C.
===========================================
Explanation:
Point P is the center of dilation. So it does not move for any dilation applied as long as its stays as the center of course.
The scale factor 4/3 = 1.33 approx means that point A's distance from P will be scaled 1.33 times larger. In other words
(A'P)/(AP) = 4/3 = 1.33
Points B' and C' are also further away than their counterparts, with relation to the center point P.
All of this means the image triangle A'B'C' is larger compared to its preimage triangle ABC.
What results is what you see in diagram C
-------------------
Side notes:
Diagram A is not correct because point B hasn't moved when it should have.Diagram B is not correct because the image triangle is smaller when it should be larger compared to its preimageDiagram D is not correct because B hasn't movedShawn would like to know the average height of the trees in the back field at school. She measures the heights of each tree in a random sample of 20 trees. The mean height of Shawn's sample is 61 inches, and the MAD (mean absolute deviation) is 2 inches.
Select all that apply
Question options :
The median height of the sample must be between 59 and 63 inches.
Another random sample of 20 trees is likely to have a mean between 57 and 65 inches.
The mean height of these 20 trees is likely to be the same as the mean height of all trees in the back field .
The mean height of these 20 trees is likely to be the same as the mean height of a second random sample of 20 trees.
Shawn would be more likely to get an accurate estimate of the mean height of the population by sampling 40 trees instead of sampling 20 trees.
Answer:

Shawn would be more likely to get an accurate estimate of the mean height of the population by sampling 40 trees instead of sampling 20 trees
Explanation:
The mean absolute deviation is the summary of absolute deviations from the central point or average of a data set. The central point measurement can be the mean, median or mode of the data set. An average absolute deviation can be used instead of a standard deviation to measure dispersion from central point.
In the above case, a sample is taken of 20 trees and there is a mean absolute deviation of 2, hence, median can be between 59 and 63. Also sample represents population, therefore mean of another sample taken is likely to be same as the previous one taken. Mean invariably gets more accurate as sample size increases too.

Answer:
You'd distribute the 2 to everything in the parenthesis. So, you'd do 2(4x) - 2(-11), which would then be 8x - (-22) = 19. You'd then add 22 to 19 to get 41. The only thing you can do from here is divide 8x by 41 to get 41/8 = x
