Decrease $820 by 32%
Answers
Answer:
557.6
Step-by-step explanation:
Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
32% = 32/100 = 32 ÷ 100 = 0.32.
100% = 100/100 = 100 ÷ 100 = 1.
Percentage decrease = 32% × 820
New value =
820 - Percentage decrease =
820 - (32% × 820) =
820 - 32% × 820 =
(1 - 32%) × 820 =
(100% - 32%) × 820 =
68% × 820 =
68 ÷ 100 × 820 =
68 × 820 ÷ 100 =

what is
5y+3=4y+8=146
Answers
Answer: y=15
Step-by-step explanation:
Solution for (5y+3)+(4y+8)=146 equation:
Simplifying
(5y + 3) + (4y + 8) = 146
Reorder the terms:
(3 + 5y) + (4y + 8) = 146
Remove parenthesis around (3 + 5y)
3 + 5y + (4y + 8) = 146
Reorder the terms:
3 + 5y + (8 + 4y) = 146
Remove parenthesis around (8 + 4y)
3 + 5y + 8 + 4y = 146
Reorder the terms:
3 + 8 + 5y + 4y = 146
Combine like terms: 3 + 8 = 11
11 + 5y + 4y = 146
Combine like terms: 5y + 4y = 9y
11 + 9y = 146
Solving
11 + 9y = 146
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-11' to each side of the equation.
11 + -11 + 9y = 146 + -11
Combine like terms: 11 + -11 = 0
0 + 9y = 146 + -11
9y = 146 + -11
Combine like terms: 146 + -11 = 135
9y = 135
Divide each side by '9'.
y = 15

Kelly purchased 6 equally-priced CDs for a total of $75.30 what is the cost per CD?
Answers
Answer:
$12.55 per CD
Step-by-step explanation:
If each CD is of equal price, you must then divide the price by the number of CD's. (75.30/6=12.55)
Answer:
$75.30/6 = $12.55 per CD
Step-by-step explanation:
Since the CDs are equally-priced, my thought is that you would divided the quantity that you purchased by your total to get your answer. So, your total, $75.30 divided by, the amount of CDs purchased, 6. This would lead you to the answer $12.55, which is the cost of each CD. To check your answer you would multiply $12.55 by 6 to get $75.30.

Step-by-step explanation:The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet " ⇒ D
Step-by-step explanation:
The boiling point of water (measured in degrees), at altitude (measured in feet), is modeled by the function T(a) = −0.0018 a + 212, where
a is the altitude measured in feet
T(a) is the boiling point of water in degree
The form of the linear function is f(x) = mx + b, where m is slope (the rate of change), and b is the y-intercept (the value of f(x) at x = 0)
By comparing between the form of the function and the given function
∴ m = -0.0018 ⇒ degrees per foot
∵ The sign of the slope is negative
∵ The slope = Δf(x)/Δx
- That means T(a) is decreasing function
∴ The boiling point is decreases when the altitude increasing
∵ -0.0018 = degrees per feet
∴ The boiling point decreases by 18 degrees as the altitude
increases by 10,000 feet or the boiling point decreases by 1.8
degrees as the altitude increases by 1,000 feet
The statement which describes the meaning of the slope is " The boiling point decreases by 1.8 degrees as the altitude increases by 1,000 feet "

in this picture lines AB and CD are parallel. Find the measures of the following angles. Explain your reasoning.
Answers
Answer/Step-by-step explanation:
1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°
2. m<ECF = m<BCD (corresponding angles)
m<ECF = 38° (substitution)
3. m<DCF + m<ECF = 180° (linear pair)
m<DCF + 38° = 180° (substitution)
m<DCF = 180° - 38° (Subtraction property of equality)
m<DCF = 142°
The measure of the following angles are as follows;
∠BCD = 38°
∠ECF = 38°
∠DCF = 142°
Angles form when a transversal cut parallel linesWhen a transversal line cut across parallel lines, the angles form include corresponding angles, alternate angles etc.
Therefore,
∠BCD = 38 degrees(alternate angles)
∠ECF = 38 degrees(corresponding angles)
∠DCF = 180 - 38 = 142 degrees(angles on a straight line)

Which linear equation has a slope of 3 and a y-intercept of -2?
y = 3x + 2
y=3x-2
y=-2x + 3
y = -2x - 3
Answers
Answer:
y=3x-2
Step-by-step explanation:
3 is the coefficient of x (slope)
-2 comes after (y-int)
linear equation y = 3x-2 has a slope of 3 and a y-intercept of -2.
What is the Slope of a line?A line's slope can be determined by looking at its slope. The slope is determined mathematically as "increase over run" (change in y divided by change in x). There are several ways to find the slope, including standard form, slope-intercept form, and point-intercept form.
Given, A linear equation that has a slope of 3 and a y-intercept of -2.
Y-intercept of -2 means at x = 0 y would be -2
The slope-intercept form of a line is
y = mx + c
where m = slope
c = constant
Substituting the values in the given equation
-2 = 0 * 3 + c
c = -2
thus, the equation of the line,
y = 3x -2
therefore, The y-intercept of the linear equation y = 3x-2 is -2, and its slope is 3.

Question 1: Write an equation.
Question 2: How long will the job be when both companies will cost the same amount?
Question 3: How much will they charge?
Answers
Answer:
BelowI hope it helps ♥Step-by-step explanation:
1. Equation representing when both companies will cost the same amount :
[tex]350 + 15x = 275 + 20x[/tex]
2. Let x equal the number of hours a job takes , then the first house painting company will charge 350+15x , the second house painting will charge 275 +20x. If the two companies charge the same amount , we will have;
[tex]350 +15x = 275+20x\\\\350 - 275 = 20x - 15x\\\\75 = 5x\\\\\frac{75}{5} = \frac{5x}{5} \\\\15 = x\\\\x = 15\:hours[/tex]
3. For a job that takes 15 hours , the first company will cost ;
[tex]350 + 15(15) = 575[/tex]
For a job that takes 15 hours , the second company will cost ;
[tex]275+20x\\\\275+20(15)\\\\275 +300\\\\=575[/tex]
