Answer:
61.538461538462%, 23.076923076923%, 15.38461538461538
Step-by-step explanation:
there are 65 candies in total
(candy bars) 40 is 61.538461538462% of 65
(gum) 15 is 23.076923076923% of 65
(lolipops) 10 is 15.38461538461538% of 65
Solve the equations by modeling. Draw the steps, using circles for the variables and squares for the numbers. 1) Solve 5x−4 = 3x +8. A. Model. B. Perform the step to have variables (circles) on only one side. C. Write the resulting step. D. Perform the step to have the variables (circles) alone on one side. E. Write the resulting step. F. Divide the variables (circles) and numbers (squares) into equal group
Answer:
x = 2
Step-by-step explanation:
Given the expression 5x−4 = 3x +8, we are to solve for the value of x;
Step 1: Collect the like terms so that the variables are on one side and Constants on the other side
5x - 3x = 8-(-4)
5x - 3x = 8+4
Step 2: Evaluate the expression in both sides
5x-3x = 8+4
2x = 12
Step 3: Divide both sides by 2
2x = 12
2x/2 = 12/2
x = 6
Hence the value of x is 2
A 20 foot ladder leans against a house the base of the ladder is 12 feet from the house. What is the distance from the ground to the top of the ladder?
Answer:
16ft
Step-by-step explanation:
Please see attached diagram depicting the above scenario.
Since the ladder leans against a house, then it forms a right angled triangle while the hypothenus is 20 foot, the distance of the base of the ladder is 12 feet from the house, hence we are required to find the point at which the ladder touches the house I.e height, rep by h.
We will apply Pythagoras theorem to solve the problem.
h^2 = 20^2 - 12^2
h^2 = 400 - 144
h^ 2 = 256
h = √256
h = 16ft
Hence, the distance from the ground to the top of the ladder is 16ft.

(-32) × 7x(-4)=x
Answer: X=0
Step-by-step explanation:
X=0
Simplify ( − 32 ) ⋅ ( 7 x ( − 4 ) ) . Tap for fewer steps... Multiply − 4 by 7 . − 32 ⋅ ( − 28 x ) = x Multiply − 28 by − 32 . 896 x = x Move all terms containing x to the left side of the equation. Tap for fewer steps... Subtract x from both sides of the equation. 896 x − x = 0 Subtract x from 896 x . 895 x = 0 Divide each term by 895 and simplify. Tap for fewer steps... Divide each term in 895 x = 0 by 895 . 895 x 895 = 0 895 Cancel the common factor of 895 . Tap for more steps... x = 0 895 Divide 0 by 895 . x = 0

Emily wants to have her résumé printed. The printing company charges $24.50 for the first 100 résumés, and then a flat rate for each additional 100 résumés. Emily pays $48.50 for 300 résumés. Write a piecewise function that describes this situation. r(x) = and calculate how much is the flat rate for each additional set of 100 résumés after the first 100 résumés are purchased? Please label your answer and round to two decimal places (hundredths) if needed.
Answer:
________{$24.50 if x ≤ 1
r(x) - - - - - {24.50 + f(3 - 2) if x > 1
Flat rate paid for each additional 100 = $12
Step-by-step explanation:
Given that :
Cost of first 100 resume = $24.50
Flat rate for each additional 100 resumes
Total amount paid for 300 resumes = $48.50
Let x = number of sets of 100 resumes
Number of sets of 100 copies = {1, 2, 3}
Since first 100 copies = $24.50
r(x) = cost of printing resume
r(x) = 24.50 if x ≤ 1
Cost of additional 100 equals ;
Let flat rate paid for each additional 100 = f
r(x) = 24.50 + f(3 - 1) if x > 1
________{$24.50 if x ≤ 1
r(x) - - - - - {24.50 + f(3 - 2) if x > 1
The flat rate paid for additional 100 resume ;
(Total amount paid - cost of first 100) / 2
($48.50 - $24.50) / 2
$24 / 2
= $12
A standard number cube that is labeled 1 through 6 is rolled 150 times. What is a reasonable prediction for the number of times it will land on a 3 or a 4?
Answer:
100 times
Step-by-step explanation:
Mathematically, the probability of getting a 3 or 4 is the probability of getting a 3 + probability of getting a 4
Probability of getting a 3 = number of 3/total number = 1/6
Probability of getting a 4 = number of 4/total number = 1/6
Thus, the probability of getting a 3 or 4 is 1/6 + 1/6 = 2/3
So the number of times will be probability multiply by number of rolls
= 2/3 * 150 = 100 times
Write the equation of the line described that passes through (12,-17), perpendicular to y = -3/7x - 5
Answer:
y + 17 = 7/3(x - 12)
General Formulas and Concepts:
Point-Slope Form: y - y₁ = m(x - x₁)
x₁ - x coordinate
y₁ - y coordinate
m - slope
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Perpendicular lines have the negative reciprocal slope of the given line's slope.
Step-by-step explanation:
Step 1: Define
Line: y = -3/7x - 5
Slope m = -3/7
Point (12, -17)
Step 2: Find slope of perpendicular line
Take the negative reciprocal of the original slope.
Slope m = 7/3
Step 3: Write perpendicular line equation
x₁ = 12
y₁ = -17
m = 7/3
y + 17 = 7/3(x - 12)

How would I find the x-intercept and the y-intercept for the equation: 6x+5y=−60?
Answer:
use the slope intercept form of the equation
y = Mx +b
Step-by-step explanation:
6x+5y = -60
5y = -6x - 60
y = (-6/5)x -12
now just plug in zero for x in that above equation ... that will be the y intercept -12
and plug in zero for y and solve for x
0 = (-6/5)x -12
12= -6/5x
(-5/6)(12) = x
-10 = x

Graph the lines given by the following equations:
y=3-1/2x
To calculate the y position given an x value, multiply the x value by -2 and subtract 3.
Answer:
switch the equation around so it looks like the slope intercept form
y= Mx + b
Step-by-step explanation:
y=3 - 1/2x
y= -1/2x +3
so when x = 0 you know this line is at 3 on the y axis
make a point on the graph at (0,3)
also you know that when x=6 they y is zero.. so
make a point on the graph at (6,0)
now draw a straight line between those two points on your graph :)
y=1/2√x
y=2x-7

Kaleb has 45 DVD's in his collection and Eileen has 61. If Kaleb buys 4 new DVD's each month and Eileen buys 2 new DVD's each month, after how many months will Kaleb and Eileen have the same amount of DVD's?
Answer: After 8 months they will have equal number of DVD's.
Step-by-step explanation:
Given: Kaleb has 45 DVD's in his collection and Eileen has 61.
Let x= Number of months
If Kaleb buys 4 new DVD's each month and Eileen buys 2 new DVD's each month , then
Total DVD's Kaleb has = 45+4x
Total DVD's Eileen has = 61+2x
When they has equal DVD's , then
[tex]45+4x =61+2x\\\\\Rightarrow\ 4x-2x=61-45\\\\\Rightarrow\ 2x=16\\\\\Rightarrow\ x=\dfrac{16}{2}\\\\\Rightarrow\ x=8[/tex]
Hence, after 8 months they will have equal number of DVD's.
