Answer: $300 per month (assumed)
Step-by-step explanation:
As figures are lacking in this question, I will use assumed figures and you can use it as a reference.
Assume Penelope had been tutoring for 60 hours a month and her hourly rate was $10 originally.
If she reduces this time to half, the amount of hours she begins to tutor is:
= 60 hours / 2
= 30 hours
At a rate of $10 an hour, her monthly income becomes:
= 10 * 30
= $300 per month
Samantha has 52 jelly beans. She decides that she will eat 4 jelly beans per minute, and she wants to create an expression that represents how many jelly beans she has left after x minutes. Which of the following expressions correctly models this situation?
Select one:
A. 4x + 52
B. x + 52
C. -x + 52
D. -4x + 52
~and also if whoever answers doesn't mind, please put an actual explanation since I just wanna be able to fully understand the concept! It would be greatly appreciated! ~
Answer:
-4x+52
Step-by-step explanation:
So we know that Samantha has 52 jelly beans and that she'll eat 4 jelly beans per minute in X minutes.
It'd be 4*x=4x
Usually, it'd be 52-4x
But you can create an equivalent
Lets say x=5
So she'd eat 20 jelly beans
52-20=32
BUT
-20+52=32
So, the answer would be D
Last week, she bought two pounds and paid $7.96, and this week she bought only one-half pound and paid $1.99. What is the unit rate for the pistachio nuts? How do you know?
Answer:
$3.98
the unit rate can be determined by dividing the total costs of the pistachio by the total pounds bought
Step-by-step explanation:
unit rate = total cost / total pounds bought
7.96 / 2 = $3.98
1.99 / 0.5 = $3.98
Suri makes $15 per hour and gets a weekly bonus of $25. Juan makes $14 per hour and gets a weekly bonus of $50. Is it possible for Suri and Juan to make the same amount of wages, y, by working the same number of hours, x, in one week?
Yes, because the slopes of the equations are different so the system of equations will have one solution.
No, because the slopes of the equations are different so the system of equations will have no solutions.
Yes, because the slopes of the equations are the same so the system of equations will have infinitely many solutions.
No, because the slopes of the equations are the same so the system of equations will have no solutions.
Answer:
Yes, because the slopes of the equations are different so the system of equations will have one solution.

help:(, i’m not sure how to do this
Answer:
i think you have to multiply the sides..
Step-by-step explanation:
Answer:
Step-by-step explanation:
1) PQ² + PR² = QR²
PQ² + 14² = 50²
PQ² + 196 = 2500
PQ² = 2500 - 196 = 2304
PQ = √2304
PQ = 48
Sin Q = [tex]\frac{opposite side}{hypotenuse}=\frac{14}{50}\\[/tex]
[tex]Cos Q = \frac{adjacent side}{hypotenuse}=\frac{48}{50}\\\\Tan Q = \frac{oppsite}{adjacent}=\frac{14}{48}\\\\\\\Sin R = \frac{48}{50}\\\\Cos R = \frac{14}{50}\\\\Tan R = \frac{48}{14}\\\\[/tex]
2) tan 48 = [tex]\frac{x}{17}[/tex]
x = 17 * tan 48 = 17 * 1.1106 = 18.8802
x = 18.8802

Answer:
13. 24ft = 8yd
14. 120in = 10 ft
15. 2 yd = 72 in
16. 5 yd = 180 in
17. 20yd = 60 ft
Step-by-step explanation:
24ft*12 in = 288 inches/36 inches(1yd) = 8yd
120in/12in = 10ft
2yd*36in = 72 in
5yd*36in = 180 in
20yd*36in = 720/12in = 60ft
1ft = 12inches
1 yd = 36 inches

Se quiere realizar la adición y multiplicación de los números enteros 43 y -32. En relación con los signos de las operaciones se puede decir que
Answer:
El caso de la adición es trivial.
La adición entre los números A y B es:
A + B
Entonces la adición entre los números 43 y -32 es:
43 + (-32)
No hace falta realizar la suma para darnos cuenta de que el resultado tendra signo positivo, esto se da porque el módulo del número positivo es mayor que el del número negativo.
Así tenemos:
43 + (-32) = 43 - 32 = 11
Para el caso de la multiplicación podemos recordar:
(+)*(+) = (+)
(-)*(+) = (-)
(+)*(-) = (-)
(-)*(-) = (+)
Entonces el producto entre un número positivo y uno negativo (como es nuestro caso con 43 y -32) siempre tendrá un signo negativo.
Entonces podemos concluir que el signo de la multiplicación entre esos dos números va a ser negativo.
También podemos resolver la multiplicación de otra forma para ver esto:
43*(-32)
43*( (-1)*32)
43*(-1)*(32)
(-1)*(43*32)
Que es claramente un número negativo.

here is a triangle prism
why is the surface area of the prism, in square centimeters?
Answer:
Step-by-step explanation:
(6 * 4) + 2(10 * 5) + (10 * 6)
Multiply 6 by 4 to get 24.
24 + 2(10 * 5) + (10 * 6)
Multiply 10 by 5 to get 50, then multiply by 2 to get 100.
24 + 2(50) + (10 * 6)
24 + 100 + (10 * 6)
Multiply 10 by 6 to get 60.
24 + 100 + 60
Add 24 to 100 to get 124.
124 + 60
Add 124 to 60 to get 184.
184 cm²
The surface area of the prism is 184 cm².

A group of four friends went out for dinner. Their bill came to $50.95. They also need to pay 8% sales tax, and want to tip their server 18% on the cost of the meal (including tax). How much will EACH friend have to pay? Round your answer to the nearest cent.
Answer:
Enter cost and tip percent to get a tip amount and total dinner amount. Also split the total amount; divide among any number of people. ... Money, Pay, Taxes. > Tip ... Enter your meal or dinner cost along with the tip percentage. ... To calculate a gratuity or tip on any calculator it is a simple multiplication. ... All rights reserved
Step-by-step explanation:
After eating at your favorite restaurant, you know that the bill before tax is $52.60 and that the sales tax rate is 8%. You decide to leave a 20% tip for the waiter based on the pre-tax amount. How much ... To figure out the tip, you need to find 20% of $52.60. 0.2 \times 52.6
The amount that each person should pay is $22.06 .
What is percent?Percentages can be stated as essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) beside the number. We can take as example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.
here, we have,
in the question ,
it is given that
total number of persons = 3 person + 1 = 4 persons
cost of the meal = $72.50
sales tax percent = 6.75%
tip percent = 15%
So , the amount of sales tax = 6.75% of cost = 0.0675 * 72.50 = $4.89
and , the amount of tip is = 15% of cost
= 0.15 * 72.50
= 10.87
So , the total amount payable is = cost + sales tax + tip
= 72.50 + 4.89 + 10.87
= 88.26
since the total number of persons is 4 ,
the amount per person is = 88.26/4 = 22.06
Therefore , The amount that each person should pay is $22.06 .

What is the slope of (12,-18) and (11,12)? Please I’m very confused.
Answer:
-30
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.
Slope
[tex] = \frac{12 - ( - 18)}{11 - 12} [/tex]
[tex] = \frac{12 + 18}{ - 1} [/tex]
