5. Rizza bought 24 face masks for Php172.80 and sold them for Php10.00 each. How much profit did she get? A. Php 62.50 B. Php67.20 C. Php40.00 D. Php67.50
Answer: Rizza got a profit of Php 67.20---B
Step-by-step explanation:
Profit = Selling Price - Cost Price
But
Selling price =Php10.00 x 24=240Php
Cost Price =Php172.80
Therefore,
Profit=Php240 -Php172.80
=Php 67.20
To find the total cost ( c ), substitute the value of (p) you just found, 285.7 , into one of the equations in the system
Answer:
c = 214.28 OR 214.275
Step-by-step explanation:
You could do c = 0.75(285.7) and you would get c = 214.275

Solve for x in the diagram below.
Answer:
x = 20
Step-by-step explanation:
The sum of the two angles is 90 degrees
x+3x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x+10-10 = 90-10
4x= 80
Divide each side by 4
4x/4 = 80/4
x = 20
Answer:
x = 20
Step-by-step explanation:
x and 3x + 10 form a right angle, then
x + 3x + 10 = 90
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20

Gilded Gifts Company hires employees to make handmade greeting cards. The manager is determining how the time spent training new employees affects their production of greeting cards. The scatter plot below shows how many greeting cards each employee made the past month and the number of hours of training the employee received. A line of best fit is drawn.
Complete the statements based on the scatter plot.
The slope of the line of best fit is
. This means that for every additional hour of training,
more greeting cards are expected to be made per month.
Without any training, an employee is expected to make
greeting cards per month.
If an employee has 70 hours of training, the employee is expected to make
greeting cards per month.
Answer:
I think its A
Step-by-step explanation:
a. The equation of the trend line is c=5x+100.
b. The equation of the trend line is c=-5x+100.
c. As the hours of training increase by 5, the greeting cards made increases by 25.
d. As the hours of training increase by 5, the greeting cards made decreases by 25.
Answer:
The slope of the line of best fit is 5.
Without any training, an employee is expected to make 100 greeting cards.
If an employee has 70 hours of training, the employee is expected to make 450 greeting cards per month.
Step-by-step explanation:
First, find the slope of the line of best fit by substituting any two points on the line into the slope formula. The following calculation uses (10,150) and (20,200).
So, the slope of the line of best fit is 5.
The y-intercept is the point at which the line crosses the y-axis or when x = 0. So, the y-intercept of the line of best fit is 100.
The equation of the line of best fit can be represented in slope-intercept form, where the slope, m, is 5 and the y-intercept, b, is 100.
A slope of 5 in this situation means that for every additional hour of training, 5 more greeting cards are expected to be made per month. The y-intercept is 100 when the number of hours of training is 0. So, without any training, an employee is expected to make 100 greeting cards.
To find the number of greeting cards an employee would produce after receiving 70 hours of training, substitute x = 70 into the equation for the line of best fit and solve for y.
So, if an employee has 70 hours of training, the employee is expected to make 450 greeting cards per month.
If – 2/3X – 1 = 4, then x =
Answer:
2/5
Step-by-step explanation:
The value of x will be x = -15/2
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We are given that the equation – 2/3X – 1 = 4
Here, we need to solve for x,
– 2/3X – 1 = 4
Now combine the like terms;
– 2/3X = 4 + 1
-2/3x = 5
x = -15/2
Therefore, the solution will be as;
x = -15/2
The value of x will be; x = -15/2

Determine the approximate average rate of change in the number of tickets sold between the 3rd and 10th days after the release.
OA.

The number of tickets sold changed at an average rate of approximately -20 tickets per day.
The number of tickets sold changed at an average rate of approximately – 7 tickets per day.
The number of tickets sold changed at an average rate of approximately –10 tickets per day.
The number of tickets sold changed at an average rate of approximately –3 tickets per day.
Ос.
D.
Answer:
-3 Is the average rate
Step-by-step explanation:
The number of tickets sold changed at an average rate of approximately -20 tickets per day. The correct answer is option A.
What is the average rate of change?The average rate of change is the average amount by which the function changed per unit throughout that time period. It is calculated using the slope of the line linking the interval's ends on the graph of the function.
The rate of change is calculated by the formula below:-
Rate of change = Final value - initial value.
From the given graph the value of tickets on the 3rd day is 100 and on the 10th day is 80. The final value of tickets is 80 and the initial value is 100.
The average rate of change in the number of tickets sold between the 3rd and 10th days after the release will be calculated as below:-
Rate of change = Final value - initial value.
Rate of change = 80 - 100
Rate of change = -20
Therefore, the number of tickets sold changed at an average rate of approximately -20 tickets per day. The correct answer is option A.

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal costs $78.48 before the discount, and they leave a 20% tip. If the tip applies to the cost of the meal before the discount, what is the total cost of the meal? Round your intermediate calculations and answer to the nearest cent.
how much does the meal cost?
Answer:
Step-by-step explanation:
c=t+p
c=0.2(78.84)+(1-0.15)(78.84)
c=0.2(78.84)+0.85(78.84)
c=15.768+67.015

The area of a triangle is 14 square units it has a side length of a and b what is the value of b if a is 1/5
Answer:
140 ft
Step-by-step explanation:
Given data
Area= 14 square feet
Height a = 1/5 ft
Base b=????
We know that the area of a triangle is given as
Area= (1/2)B*H
substitute
14= 1/2* B* 1/5
14= B/10
cross multiply
B= 140
Hence the base is 140 ft

The equation has a minimum value with a y coordinate of -21 Oc. the equation has a minimum value with a y coordinate of -27 Od. The equation has a maximum value with a y coordinate of -21
Answer:
D. The equation has a maximum value with a y coordinate of -21Step-by-step explanation:
The quadratic equation has the extreme value at vertex with x-coordinate of
x = -b/2aFor the given equation the vertex is:
x = -12/2(-3) = 2The value of y at x = 2 is:
y = -3(2²) + 12(2) - 33 = -12 + 24 - 33 = -21Since the leading coefficient is negative, the extreme is the maximum for the given equation.

7 minus n
3

4
StartFraction n Over 7 EndFraction
Expression number:
To find the difference between two numbers you would subtract them.
You are told the first number is 7 and you want to find the different of 7 and a number, which is represented by the letter n.
To find the difference you would subtract n from 7, which would be written as 7 - n
The correct answer would be 2. 7 - n ( 7 minus n)
Answer: 7 - n (Look at the explanation to understand it clearly)
Normally you'll subtract this equation, but since there isn't a number but is a variable, you would have to rewrite it.
In this problem, we would represent n as the variable and 7 as the number. Rewrite it like this:
7 - n
Or you could say it like this:
A number decreased by 7.
"A number" would represent the variable.
Hence, your answer is 7 - n.

Mr. Torres bought 3 chairs on Saturday. He paid d dollars for each chair. Mr. Torres received $15 dollars in change when he bought the chairs. Which expression can be used to find the total amount Mr. Torres paid for these chairs
Answer: c. 3d + 15
Step-by-step explanation:
Mr. Torres paid d dollars for each of the three chairs which gives the expression of:
= 3 * d = 3d
He then paid with an amount that was greater than this 3d and got a change of $15.
That total amount that he paid is therefore, the price of the three chairs added to the $15 that he received back.
= 3d + 15
