7. On Monday, Jeremiah had a debt of $92.80 after buying a pair of Jordan's. Jeremiah was
paid $126.42 from his job at Home Depot on Tuesday. After depositing his check from
Home Depot, what is the amount, in dollars, in Jeremiah's bank account?
A $33.62
B. $219.22
C. $174.42
D. $42.22
Answer:
A $33.62
Step-by-step explanation:
To figure this out you have to take -92.80 and add 126.42 to get $33.62. Have a great day and LEAVE ME ALONE PLZ! <3
Answer:
-92.80+126.42=33.62
Step-by-step explanation
Since you owe $92.80 it would be a negative. So it would be like this.
126.42-92.80= 33.62
Or
-92.80+126.42=33.62

A spinner has 8 equal sectors with different letters for each sector, as shown below:
A spinner with 8 equal sectors is shown. The sectors are labeled B, Y, G, P, O, V, M, and R.
Hamlet spins the spinner 13 times, and it stops at the letter R 9 times. If he spins the spinner a 14th time, what is the theoretical probability that this time it will stop at the letter R?
Answer:
The theoretical probability of obtaining letter 'r' at the 14th spin is:
1/8
Step-by-step explanation:
It is given that:
A spinner has 8 equal sectors with different letters for each sector.
The sectors are labeled b, y, g, p, o, v, m, and r.
Hamlet spins the spinner 13 times, and it stops at the letter r 9 times.
We are asked to find the theoretical probability that we will get letter r at the 14th spin.
The theoretical Probability is given as the ratio of number of favorable outcomes to the total number of outcomes.
Hence, the theoretical probability of obtaining letter 'r' at the 14th spin is:
( As there are a total of 8 outcomes( or 8 sectors) out of which there is only one sector which is red)

What is the measure of angle b?
Just show me some work. I don’t need anything else I know the answer
Answer:
well i mean i guess you know what it is
Step-by-step explanation:
We know that all of the angles in a triangle must add up to 180. so to find the measure of angle b, we can add the two known angles together, and take that number away from 180. (we would do this to find out how much is left to complete a full 180 degrees) 115+31=146. 180-146=34. since all of the angles 31, 115, and 34 add up to 180, we know that 34 is the correct answer

To determine the number of trout in a lake, a conservationist catches
185 trout, tags them and throws them back into the lake. Later,44 trout are caught;
11 of them are tagged. How many trout would the conservationist expect to be in the lake?
11/44 reduces to 1/4
1/4 of the trout caught were tagged.
185 trout were tagged
185 / 1/4 = 740
There are 740 total trout.

1. Is Andres triangle congruent to the one on the data card?
2. What other information could Andre have asked for to be sure the triangle he drew is congruent?
Answer:
1. Yes, both of the triangles are congruent to each other
2. Are the sides on the triangles from AB∠, BC∠, and CA∠ the same length as Andres triangles?
Step-by-step explanation:
Congruent means the same so number one is asking if the triangles are the same and yes the are because they have the same angles

245 ÷ 5 = 49
tickets to the zoo cost $12 for adults and $8 for children the school has a budget of $240 for the field trip. an equation representing the budget for the trip is 240 = 12x + 8y here is s graph of the equation
Answer: x=

y+20
Step-by-step explanation
240=12x+8y
Step 1: Flip the equation.
12x+8y=240
Step 2: Add -8y to both sides.
12x+8y+−8y=240+−8y
12x=−8y+240
Step 3: Divide both sides by 12.
12x

solve for m with step by step work please i need that more then the answer
Answer:
m = 7
Step-by-step explanation:
Step 1:
- 6m + 8 = - 6 - 4m Equation
Step 2:
8 = - 6 + 2m Add 6m on both sides
Step 3:
14 = 2m Add 6 on both sides
Step 4:
m = 14 ÷ 2 Divide
Answer:
m = 7
Hope This Helps :)
Answer:
8+6=6m-4m( because when 6goes to first its+ be- and -6m goes right it be 6m it has own and rule).
then,
14=2m
14/2 =m
7 =m

Answer:
Step-by-step explanation:
opens down refers to the value of a being negative or positive. If it opens down, then a is negative.
shifting left or right refers to the value of h
shifting up or down refers to the value of k
For the first one: y = -a (x+8)² + k
second one: y = -a(x+h)² + 7

Connor has hired two painters to paint his house. The first painter charges $12 an hour and the second painter charges $11 an hour. It will take 15 hours of labor to paint the house. A. Wrote a polynomial to represent the total cost of the job if the first painter does x hours of work. B. Write a polynomial to represent the total cost of the job if the second painter does y hours of labor.
Answer:
Cost = cost of first painter + cost of second painter
= $12/hr * hours worked + $11 * hours worked
where x is the hours the first painter works
C(x) = 12 x + 11 ( 15 - x)
= 12 x + 165 - 11x
= x + 165
C(x,y) = 12 x + 11 y
where y = 15 - x because the total hours is 15
