Answer: Brice's initial amount is smaller than Yolanda's.
Step-by-step explanation: To find Yolanda's slope, we do 180-120, and then 4-2. This yields a slope of $30 per month, making Yolanda's slope equal to Brice's. Using that slope, we now know that Yolanda would need a much higher initial amount.

Determine the direction and degree of rotation used to create the image.
90° counterclockwise rotation
270° clockwise rotation
90° clockwise rotation
180° counterclockwise rotation
Answer: 90° clockwise rotation (I think you posted this question twice? It seems to have the same answer as the previous one I answered)
Step-by-step explanation:
The rules for rotation are below:
90° clockwise rotation = (x, y)→(y, -x)
270° clockwise rotation = (x, y)→(-y, x)
180° counterclockwise rotation = (x, y)→(-x, -y)
90° counterclockwise rotation = (x, y)→(-y, x)
Let's take point B. Point B's coordinates are (3, -2). Point B' is (-2,-3). -x would be -3, and y stays the same.
Therefore, the answer is 90° clockwise rotation.

Triangle PQR has vertex coordinates at P(4, 0), Q(6, 4), R(5, 1). If the triangle is translated so that Q′(9, 4), determine the translation direction and number of units.
3 units down
3 units up
3 units to the right
3 units to the left
3 units to the right.
The direction is to the right, and the number of units is 3.
For the first step, we need to compare the given position of point Q (6, 4) with its new position Q' (9, 4). In the x-axis, the x-coordinate of Q' is greater than the x-coordinate of Q,i.e., 9>6. This means that the triangle has been translated to the right. To get the number of units we subtract the new Q' value from the given Q value, 9-6=3. Hence the number of units is 3. In the y-axis, the y-coordinate of Q' is the same as the y-coordinate of Q,i.e., 4=4. This means that there has been no vertical translation.
Hence Option C is the correct answer.

A car uses 3 gallons of gas to travel 75 miles. At this rate, which equation can be used to determine g, the number of gallons of gas the car uses to travel 350 miles?
Answer:
3/75 = g/350where g is the number of gallons of gas the car uses to travel 350 miles. To solve for g, we can cross-multiply:3 × 350 = 75 × g1050 = 75gDividing both sides by 75, we get g = 14Therefore, the equation that can be used to determine g is:3/75 = g/350, or simply g = 14.
A fair 6-sided die is rolled 360 times. What is a reasonable prediction for the number of times the event of landing on an odd number will occur?
60
180
240
320
Answer:
correct answer is B) 180.
Step-by-step explanation:
When rolling a fair 6-sided die, there are three odd numbers (1, 3, and 5) and three even numbers (2, 4, and 6). The probability of rolling an odd number on a single roll is therefore 3/6 or 1/2.
If the die is rolled 360 times, we can expect that the event of landing on an odd number will occur roughly (1/2) * 360 = 180 times, on average. Therefore, the most reasonable prediction for the number of times the event of landing on an odd number will occur is 180.
The students in Dr. Doug's second period math class measured the time they spent watching television over the weekend and used the data to make a dot plot. What percent of the students in Dr. Doug's second period math class spent more than 75 min watching television?
Answer: 20%
Step-by-step explanation: Without the dot plot or the raw data, it's impossible to give an exact percentage. However, we can make an estimate based on the dot plot.
Let's say that the dot plot has a range of 0-150 minutes, with each dot representing one student. We can count the number of dots that are above 75 minutes and estimate what percentage of the total dots that represents.
For example, let's say there are 20 dots above 75 minutes and a total of 100 dots on the dot plot. Then the percentage of students who spent more than 75 minutes watching TV would be:
20/100 * 100% = 20%
Again, this is just an estimate based on hypothetical numbers. The actual percentage could be different depending on the data in the dot plot.

8) The length, width and height of a rectangular prism are 16 feet, 7 feet and 27 inches respectively. What is its
volume in cubic feet?
Answer:252 cubic feet
Step-by-step explanation:
To find the volume of a rectangular prism, you will use the formula:
V = l x w x h
V is the volume, l is the length, w is the width, and h is the height.
So we would multiply all the given measurements and find the volume but one of the measurements is given in inches instead of feet, which is what the answer should be in, cubic feet.
To convert inches to feet, divided inches by 12. Because one foot makes 12 inches, and 12 inches makes one foot. Just like the subs at Subway, a half footlong is 6 inches and a footlong is 12 inches. Now 27/12 is 2.25, so 2.25 ft is the measurement in feet. Now we can multiply all the measurements to get the volume.
V = l x w x h
V = 16 ft x 7 ft x 2.25 ft
V = 252 ft^3
Always remember to cube the solutions to volume and square the solutions to area.

The total number of hours each student spends volunteering in their community is shown in the stem-and-leaf plot.
Which statement is supported by the data in the stem-and-leaf plot?
A.
The most common number of hours volunteered is 25.
B.
The number of students who volunteered more than 30 hours is greater than the number of students who volunteered fewer than 30 hours.
C.
The number of students who volunteered between 9 and 20 hours is greater than the number of students who volunteered more than 40 hours.
D.
The most common number of hours volunteered is 42.
Answer:
C
Step-by-step explanation:
The most common number of hours volunteered is 34, so the answer can't be A or D. 7 students volunteered more than 30 hours, while 12 students did less than 30 hours, which means B is incorrect. There are 3 students that volunteered more than 40 hours and 6 that volunteered between 9 and 20 hours, which means C is correct.

8th grade math i mark as brainliest
Answer:
52
Step-by-step explanation:
Since your finding what c is, you will use the Pythagorean Theorem formula. [tex]A^{2}[/tex] + [tex]B^{2}[/tex] = [tex]C^{2}[/tex]
A² + B² = C² --> Step 1: Set up the formula.
20² + 48² = C² --> Step 2: Plug in 20 for a and 48 for b.
400 + 2304 = C² --> Step 3: 20 x 20 = 400, 48 x 48 = 2, 304.
2704 = C² --> Step 4: Add both 400 and 2, 304 to get 2, 704.
√2704 = √c² Step 5: Square root both 2, 704 and [tex]C^{2}[/tex].
52 = c --> C = 52.
So your answer is 52. Hopefully this helps, let me know if it doesn't.
Seki, a professional bike racer, takes out a loan to buy her first high-end bike. The bike costs $seven thousand, five hundred, and the simple interest loan is for thirty months. She calculates that she will end up paying $seven hundred fifty in interest over the life of the loan.
.
What is the interest rate on Seki's loan?
The following sentence or sentences contain missing information in the form of one or more blanks. For each blank, there will exist a corresponding input field. Use the input fields to complete the sentence or sentences.
Interest Rate =
%
What is the total amount Seki will pay when the loan is due?
Balance = $
Answer: Seki's interest rate for the bike is 33.33% each year; Seki will owe $8250 at the end of the loan.
Step-by-step explanation:
To calculate the simple interest rate, the equation is: r = (1/t)(A/P - 1)
Where:
r - interest rate per year (in decimal format)
t -time (loan time in years)
A - total accrued amount (initial price paid + amount of interest paid)
P - principle (initial price paid)
For this scenario:
r = (1 / 30)(8250 / 7500 - 1)
- simplify both sets of parentheses: 1 / 30 and 8250 / 7500
r = (.033333)(1.1 - 1)
- simplify the second set of parentheses
r = (0.033333) x 0.1
- multiply
r = 0.0033333
- convert r (as a decimal) to R (as a percentage) by multiplying r x 100
R = .3333
The interest rate on Seki's loan is 33.33%
The total amount Seki will pay:
equation for total due: A = P + I
Where:
A - total accrued amount (initial price paid + amount of interest paid)
P - principle (initial price paid)
I - amount paid in interest that accrued over time
For this scenario:
A = 7500 + 750
A = 8250
Seki will pay $8250 when the loan is due.
Roll a standard number cube. Then flip a quarter. Write the sample space in your workbook and enter the number of outcomes below.
Answer:
The sample space for rolling a standard number cube and flipping a quarter can be represented using a table, where the rows correspond to the possible outcomes of the coin flip and the columns correspond to the possible outcomes of the number cube roll:
| H | T
---------------
1 | 1H| 1T
2 | 2H| 2T
3 | 3H| 3T
4 | 4H| 4T
5 | 5H| 5T
6 | 6H| 6T
In the table, "H" represents heads and "T" represents tails. Each cell in the table represents a possible outcome of the experiment, where the first element corresponds to the number cube roll and the second element corresponds to the coin flip.
The total number of outcomes in the sample space is equal to the product of the number of outcomes for each of the two experiments. Since there are 6 possible outcomes for rolling a standard number cube and 2 possible outcomes for flipping a quarter, the total number of outcomes in the sample space is 6 x 2 = 12.

Barbara runs a lemonade stand to raise money for Barton Children's Hospital. Last weekend, she made 8 liters of lemonade to sell. Saturday was rainy, so she only sold 8 glasses. The weather was better on Sunday, so she sold 24 glasses. If each glass holds 200 milliliters, how many liters of lemonade does Barbara have left?
PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!
Answer:
1.6 liters of lemonade
Step-by-step explanation:
There are 1000 milliliters in one liter so she made 8000 milliliters of lemonade
Next we have to figure out how many milliliters of lemonade she sold each day:
Saturday: 200 milliliters of lemonade in a glass * 8 glasses = 1600 milliliters of lemonade sold
Sunday: 200 milliliters of lemonade in a glass * 24 glasses = 4800 milliliters of lemonade sold
1600 + 4800 = 6400 total milliliters of lemonade sold
Since there are 1000 milliliters in one liter, we have to divide 6400 by 1000:
6400 ÷ 1000 = 6.4 liters
Lastly, we have to subtract 6.4 from 8:
8 - 6.4 = 1.6 liters of lemonade

Hey,
You can see that the line next to both angles is straight, so it is equivalent to 180 degrees. This means both other angles are supplementary (they add to equal 180). Therefore, 78 + (5q+2) = 180.
Here are the steps to solve:
1) Subtract 78 from the 180 total.
180 - 78 = 102
2) Reassign the value of the variable term
5q+2 = 102
3) Subtract 2 from both sides.
5q = 100
4) Divide by 5
q = 20
