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?
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.

Use the graph to answer the question. Graph of polygon ABCD with vertices at 1 comma negative 1, 3 comma negative 5, 7 comma negative 5, 5 comma negative 1. A second polygon A prime B prime C prime D prime with vertices at 1 comma negative 6, 3 comma negative 10, 7 comma negative 10, 5 comma negative 6. Determine the translation used to create the image. 5 units down 5 units up 1 unit down 1 unit up
Answer:
The translation used to create the image from polygon ABCD to polygon A' B' C' D' is 5 units down.
Step-by-step explanation:
You can see this by observing that all of the y-coordinates in A' B' C' D' are 5 units less than their corresponding y-coordinates in ABCD. Specifically, the y-coordinates of the vertices in ABCD are (-1, -5, -5, -1), and the y-coordinates of the vertices in A' B' C' D' are (-6, -10, -10, -6).
Therefore, the vertical shift or translation used to create the image is 5 units down.
Answer:
5 units down.
Step-by-step explanation:
To solve this question, we need to compare the coordinates of the corresponding vertices of the two polygons and see how they change. A translation is a type of transformation that slides a figure by a certain distance and direction without changing its size or shape. The rule of a translation can be written as (x, y) -> (x + h, y + k), where h and k are the horizontal and vertical shifts, we can see that:
A (1, -1) maps to A’ (1, -6), which means x stays the same and y decreases by 5.B (3, -5) maps to B’ (3, -10), which means x stays the same and y decreases by 5.C (7, -5) maps to C’ (7, -10), which means x stays the same and y decreases by 5.D (5, -1) maps to D’ (5, -6), which means x stays the same and y decreases by 5.We can see that all the vertices have the same change in their coordinates: x stays the same and y decreases by 5. This means that the translation used to create the image is 5 units down. The rule of this translation can be written as (x, y) -> (x, y - 5). Therefore, the answer is 5 units down.

Answer: 360.67
Step-by-step explanation:
425.82 + 120.75 = 546.57
546.57 - 185.90 = 360.67
deposit = adding

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

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
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.

-4y = 72
Horozontal or vertical??
Answer:
horizontal
Step-by-step explanation:
You want to know if the equation -4y = 72 describes a horizontal or vertical line.
Constant equationThe equation reduces to ...
-4y = 72
y = -18 . . . . . . . . divide both sides by -4
The points on a graph that have y-coordinate -18 will form a horizontal line. They are all 18 units below the x-axis. The line is parallel to the x-axis.

Additional comment
The equation x = constant describes a vertical line.
If you are in doubt, you can always graph the equation with your graphing calculator.

Answer:12/13
1/2
5/8
1/4
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

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.

Answer: x=16 degrees
Step-by-step explanation:
Let's assume that angle (7x-2) is angle P, and angle (4x+6) is angle Q. The lines are parallel, so angle P is correspondent to Angle F, meaning that they are equal.
So we know that a straight line is 180 degrees, so we can form an equation like this: Angle F+ Angle Q= 180 degrees.
Now let's add in the information:
7x-2+4x+6= 180 degrees
11x+ 4= 180
11x= 180-4
11x = 176
x= 16 degrees

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.
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%.

A gardener uses a total of gallons of gasoline in one month. Of the total amount
of gasoline, was used in his lawn mowers. How many gallons of gasoline did the
gardener use his lawn mowers in one month?
Answer:
D. 36.9
Explanation:
three-fifths of 61.5 is 36.9!
Answer:
D. 36.9
Step-by-step explanation:
The total amount of gallons the gardener typically uses in a month is 61.5 gallons. Since the gardener used 3/5 gallons, we know that 5/5 is 61.5 gallons. So you would have to divide 61.5 by 5 in order to get 1/5 of the gallons which would be 12.3. Then you have to multiply the 12.3 by 3 in order to get 3/5 of how much the gardener used which is 39.9 gallons. I hope this helped!
I dont need an answer I just need help.. The picture below, is it just 9x9 and like 6x6 or is it 9x2 and 6x2? And then the answer would be c x 2 or c x c?
Answer: 45
Step-by-step explanation:
Pythagorean Theorem is a^2+b^2=c^2
In this case it would be 9^2-6^2 which is 45
Answer:
In this case, it would be 9x9 and 6x6
Step-by-step explanation:
The ² in the problem means to multiply the number by itself, like 9x9. It's called the square.
a² + b² = c²
eg.
(a x a) + (b x b) must be = (c x c)
c = hypotenuse which means it is the longest part, which is why it is a² + b² = c²
