Answers
Answer:
The first yes, the second no.
Step-by-step explanation:
Proportional means they follow a constant proportion. In the first example, 1 hr is 4.5 ft, so the constant is 4.5, which means that everything in the top line multiplied by 4.5 should equal the bottom line. 2*4.5=9, 3*4.5=13.5, if you check it it all works out. But on the second problem, 2 hrs is 20 ft, which means that the constant should be 10, because 2/2 is 1 and 20/2 is 10, but 4*10 does not equal 30, it equals 40, so right off the bat we know it’s not proportional.

1/8
Step-by-step explanation:1)there are 4 kings in a deck so the probability of not getting them is 1-(the probability of getting them)=1-(4/52)=12/13
2)there are heads and tails so the P of getting ont of them is half=1/2
4)there are 4 suits in a deck so 52/4=13; therefore, there are 13 hearts in the deck so 13/52=1/4
5)and means multiplication, so flipping heads*drawing a heart= question 2* question 4 =1/2 * 1/4=1/8
3) its a little complicated so you can consider it as the last option possible and choose, anyways "or" means addition so add the two probabilities to get 5/8

A waitress sold 15 ribeye steak dinners and 28 grilled salmon dinners, totaling $551.97 on a particular day. Another day she sold 24 ribeye steak dinners and 14 grilled salmon dinners, totaling $581.91. How much did each type of dinner cost?
Answers
Answer:
Ribeye (ea) = $18.54
Salmon (ea) = $9.78
Step-by-step explanation:
x is the price for each ribeye steak
y is the price for each grilled salmon
15x + 28y = $551.97 (a)
24x + 14y = $581.91 (b) -----(x2)------> 48x + 28y = 1163.82 (c)
Subtract c with a
48x + 28y = 1163.82 (c)
15x + 28y = $551.97 (a)
=================== -
33x = 611.85
x = 18.54
Put the value of x into a
15 · 18.54 + 28y = 551.97
278.1 +28y = 551.97
28y = 273.87
y = 9.78
In conclusion, the price of 1 ribeye is $18.54, and the price of 1 salmon is $9.78.

A 25-foot magazine rack begins 20 feet south of the checkout desk and continues south. What are the coordinates of the beginning and end of the magazine rack? Explain or show how you got your answer. ANSWER CORRECTLY WITH AN EXPLANATION
Answers
Answer: The coordinates of the beginning of the magazine rack are (0,-20), and the coordinates of the end of the magazine rack are (0,-45).
Explanation:
The magazine rack begins 20 feet south of the checkout desk, so its starting point is 20 feet below the x-axis. This gives us the coordinates (0,-20) for the beginning of the rack. Since the rack is 25 feet long, it extends 25 feet to the south of its starting point. Therefore, the endpoint of the rack is 20 feet (the starting point) minus 25 feet (the length of the rack), or -5 feet south of the checkout desk. This gives us the coordinates (0,-45) for the end of the rack.
Brainliest?
Let's assign the x-coordinate of the checkout desk as 0. Then, the x-coordinate of the beginning and end of the magazine rack will also be 0.
The y-coordinate of the beginning of the magazine rack is 20 feet south of the checkout desk, which means it is 20 feet less than the y-coordinate of the checkout desk. If we assume that the y-coordinate of the checkout desk is y = 0, then the y-coordinate of the beginning of the magazine rack is y = -20.
To find the y-coordinate of the end of the magazine rack, we add the length of the rack (25 feet) to the y-coordinate of the beginning of the rack (-20 feet). This gives us y = 5.
Therefore, the coordinates of the beginning of the magazine rack are (0,-20) and the coordinates of the end of the magazine rack are (0,5).

Piper has $425.82 in her checking account. How much does she have in her account after she makes a deposit of $120.75 and a withdrawal of $185.90?
Answers
Answer: 360.67
Step-by-step explanation:
425.82 + 120.75 = 546.57
546.57 - 185.90 = 360.67
deposit = adding
withdrawal = subtraction
Answer:
$360.67
Step-by-step explanation:
Break it down:
Original: $425.82
Deposit: $120.75
Withdrawal: $185.90
What is a deposit?
A deposit is used in terms of money, and it's when you put money into your account/bank. We would use addition.
What is a withdrawal?
A withdrawal is also used in terms of money, and it's when you take money out. We would use subtraction.
Let's write an equation:
425.82+120.75
=546.57
546.57-185.90
=360.67
Piper will have $360.67 after her 2 transactions. Hope this helps! :)

Answer: $88
Step-by-step explanation:
1. Plug in the given data into the formula.
p = 80
r = 0.1 (represents 10%)
t = 1 year
2. Solve for i based on the formula's values
i = (80)(0.1)(1) = 8
Interest earned is $8 but THIS IS NOT THE FINAL ANSWER!
3. Add i (interest) to p (starting amount)
Elena started with $80, so the interest of $8 is added for a final answer of $88 after one year.
Joseph has a fair dice with 4 faces numbered 1 to 4.
He also has a fair dice with 6 faces numbered 1 to 6.
He rolls both dice.
Find the probability of rolling a different number on each dice.
Answers
Answer:
To find the probability of rolling a different number on each dice, we can determine the total number of possible outcomes and the favorable outcomes.
The total number of possible outcomes when rolling a 4-sided die and a 6-sided die is the product of the number of sides on each die: 4 × 6 = 24.
The favorable outcomes occur when we roll a different number on each die. We can calculate this by considering all the possible combinations.
For the first die (4-sided), there are 4 possible outcomes.
For the second die (6-sided), there are 6 possible outcomes.
Since we want different numbers on each die, the total number of favorable outcomes is 4 × 6 = 24.
Therefore, the probability of rolling a different number on each die is:
Probability = (Number of favorable outcomes) / (Number of total outcomes)
Probability = 24 / 24
Probability = 1
Hence, the probability is 1 or 100%.

The total area of the figure is 52 square feet by adding the areas of the parallelogram and trapezoid
Calculating the total areafrom the question, we have the following parameters that can be used in our computation:
parallelogram and trapezoid
Wher we have
Area of parallelogram = 7 * (6 - 2)
Area of parallelogram = 28
Also, we have
Area of trapezoid = 1/2 * (7 + 5) * 4
Area of trapezoid = 24
So, we have
total area = 28 + 24
total area = 52
Hence, the total area is 52 square feet
