What is "A" in this problem equal to? 4/5 = 24/A. Explain your answer! *
Answer:
A = 30
Step-by-step explanation:
cross multiply to get A out from the denominator
4/5 = 24 /A
4A = 24 x 5
4A = 120
4A/4 = 120/4 divide
A = 30
June is driving for brookline massachusetts, to brooklyn,new york. the cities are 200 miles apart. pretend June lives in a world in which she encounters no traffic jams and can drive at a constant speed of 50 mph the entire way. consider the following function. the distance June has traveled , c, is a function of her driving time t. what is the range of the function?
The range of the function c = 50t + 200 is given by [200, ∞).
What is a linear equation?A linear equation is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the y intercept.
Let c represent the distance travelled in t hours, hence:
c = 50t + 200
The range of the function c = 50t + 200 is given by [200, ∞).

Peyton is a salesperson who sells computers at an electronics store. She makes a base pay amount of $60 per day regardless of sales and she earns a commission of 2.5% of the dollar amount of all sales that she makes. Write an equation for P,P, in terms of x, representing Peyton's total pay on a day on which she sells xx dollars worth of computers.
Answer:
Step-by-step explanation: if Peytons base pay= $60 plus she earns commission on $x (computers sold)
P= $60+ (0.025x)
You would multiply by 0.025 as this equals 2.5%

Please answer ASAP. Thank you.
Answer:
Slope is 1/2
Step-by-step explanation:
up one, right 2
How I learned it: Rise/ Run
Hope that helps!
Answer:
1/2
Step-by-step explanation:
Slope is defined as rise over run. In the graph, you can see that for every 2 units in the positive x-direction, there will be 1 unit in the positive y-direction. Therefore, the answer is change in x/change in y = 1/2

Fernando has been saving money to buy an e-book reader. A store has just marked down the price of its readers by 40%. Each reader comes with a mail-in rebate for $25. If the reader used to cost $150, what will Fernando's final price be after the markdown and rebate? The total amount off includes the markdown and rebate. What is the total amount off?
Answer:
$85Step-by-step explanation:
We are expected to solve for the amount off the reader after 40% discount and $25 refund(rebate)
Now given that the book is $150
40% of 150
=(40/100)*150
=0.4*150
=$60
The total amount off includes the markdown and rebate.
the total amount is
60+25=$85

Step-by-step explanation:
Which of the following properties are true for rigid transformations?
i. Increases or decreases the size of the figure
ii. Moves the location of the figure.
iii. Changes the shape of the figure
O ii only
O i and ii
O ii and in
O i, ii, and in
Answer:
The first choice is correct. ii only.
Step-by-step explanation:
A rigid transformation changes the location of the shape without changing its size. There are three basic rigid transformations: reflections, rotations, and translations.
We are given these properties:
i. Increases or decreases the size of the figure
ii. Moves the location of the figure.
iii. Changes the shape of the figure.
Let's analyze each choice below:
O ii only . This is true. The other two properties are non-rigid transformations. Correct
O i and ii . This is not true. Increasing or decreasing the size of the figure is a non-rigid transformation. Incorrect.
O ii and iii. Changing the shape of the figure is a non-rigid transformation. Incorrect.
O i, ii, and iii. Properties i and iii are non-rigid transformation. Incorrect.
what is the m∠q ?????????????????????? help i taking a test and imma get beat if i fail
Answer:
Unlike the previous problem, this one requires application of the Law of Cosines. You want to find angle Q when you know the lengths of all 3 sides of the triangle.
Law of Cosines: a^2 = b^2 + c^2 - 2bc cos A
Applying that here:
40^2 = 32^2 + 64^2 - 2(32)(64)cos Q
Do the math. Solve for cos Q, and then find Q in degrees and Q in radians.
Step-by-step explanation:
Answer:
x = 30
Step-by-step explanation:
this is an isosceles triangle, which mean that PRQ and PQR are equal.
all sides of a triangle equal 180.
using this, you can make the following equation:
x + (2x + 15) + (2x + 15) = 180
combine like terms
5x + 30 = 180
subtract 30 from both sides
5x = 150
divide both sides by 5
x = 30

Jackson went into a movie theater and bought 8 bags of popcorn and 2 candies, costing a total of $58. Cooper went into the same movie theater and bought 4 bags of popcorn and 5 candies, costing a total of $49. Write a system of equations that could be used to determine the price of each bag of popcorn and the price of each candy. Define the variables that you use to write the system.
Answer:
Jackson: 8p + 2c = 58
Cooper: 4p + 5c = 49
Step-by-step explanation:
p= popcorn
c= candies
When you write this equation, have the cost on one side of the equation and the coefficients on the other.

Mother is three times as old as her daughter. Three years ago she was four times as old as her daughter was. Find their present ages.
Answer:
daughter = 9yrs
mother = 27yrs
Step-by-step explanation:
let age of daughter be x
age of mother = 3x
by qsn,
three yrs ago,
4 (x-3) = 3x-3
4x-12 = 3x-3
4x-3x = -3+12
× = 9 yrs (age of daughter )
3x = 3×9 = 27 yrs ( age of mother)

HELP ASAP Find the equation of a line that goes through the points (8, -9) and (-4, 15).
Answer:
Your answer is: y= -2x+7
Step-by-step explanation:
Hope this helped : )
The equation of a line that goes through the points (8, -9) and (-4, 15) is y = -2x + 7
The formula for calculating the equation of a line is expressed as y = mx+ b
m is the slope of the line
b is the y-intercept
Given the coordinate points (8, -9) and (-4, 15)
Get the slope of the line;
[tex]m =\frac{15-(-9)}{-4-8}\\m=\frac{24}{-12} \\m = -2[/tex]
Get the y-intercept of the line
Recall that y = mx + b
15 = -2(-4) + b
b = 15 - 8
b = 7
Get the required equation in the form y = mx + b
y = -2x + 7
Hence the equation of a line that goes through the points (8, -9) and (-4, 15) is y = -2x + 7
