26$
Step-by-step explanation:
1% = 4/100 * 25
1% = 1
25 + 1 = 26
Another way to solve
Percentage increase = 100% + 4%
104/100 = 1.04
1.04 * 25 =26
y = -2x + 13 when x = 6
Answer: 1
Work: After plugging in the 6 in the X, the new equation is -2(6) + 13. After doing the multiplication of -2 and 6, you get -12. Add -12 + 13, and the answer (Or y) equals 1.

Diego cut 7 smaller boards of equal length from a board that is 9 and one-third feet long. How long is each of the 7 smaller boards?
Answer:
1 1/3 feet long
Step-by-step explanation:
Answer:
Each of the seven smaller boards will be 1.3 feet long
Step-by-step explanation:
We must divide 9 1/3 by 7
9 1/3 / 7 = 1.333286
We now have to round to the nearest tenth which would give us:
1.3
So our final answer would be 1.3
WORTH 15 POINTS!! - Eileen's Energy Bars has determined that an energy bar measuring 3.25 inches long has a z-score of +1 and an energy bar measuring 3.50 inches long has a z-score of +2.
What is the standard deviation of the length of energy bars produced at Eileen's Energy Bars?
3.5
3.25
0.75
0.25
Answer:
0.25
Step-by-step explanaition:
The z-score represents how many deviations a value is from the mean. When the bar measures 3.25, the z-score is +1. When the bar measures 3.50, the z-score is +2. You'll notice that whenever the bar size increases by 0.25, the z-score goes up +1. So, the standard deviation from the mean must be 0.25.

What is the slope of AB in parallelogram ABCD?
The slope of the line [tex]\overline{AB}[/tex] is the rate at which the line rises at a point.
[tex]\mathrm{The \ slope \ of \ \overline{AB} \ is \ D.} \ \dfrac{5}{2}}[/tex]
Reasons:
The slope of a line is given by the ratio of the rise to the run of the line
The coordinates of point A = (-9, -4)
The coordinates of point B = (-5, 6)
The rise of the line [tex]\overline{AB}[/tex] = The difference in the y-values = (6 - (-4)) = 10
The run of the line [tex]\overline{AB}[/tex] = The difference in the x-values = (-5 - (-9)) = 4
[tex]Slope \ of \ \overline{AB}= \dfrac{Rise \ of \ line \ \overline{AB}}{Run \ of \ line \ \overline{AB}}[/tex]
Therefore
[tex]Slope \ of \ \overline{AB}= \dfrac{10}{4} = \dfrac{5}{2}[/tex]

Answer: (C) 42 cm
Work Shown:
(length on paper)/(real length) = (length on paper)/(real length)

Your answer:
x = 15
x = 13
x = 60
ox=37
pls helpppppo
Answer:
x = 13
Step-by-step explanation:
All triangles equal 180 degrees
Since this is an equilateral triangle, all angles have the same measurement
180 degrees divided by 3 angles = 60 degrees per angle
Make an equation based on the info given:
60 = 5x - 5
Solve:
*add 5 to both sides*
65 = 5x
*divide both sides by 5*
13 = x
-x + y = 5
x - 5y = 2 ---> x= 5y + 2
I have solved the second equation for x. What is the next step if solving this system with substitution?
A. -(5y+2) + y = 5
B. -x + y = 5 + 5y + 2
C. None of the Above
D. -x + 5y + 2 = 5
Answer:
A. -(5y+2) + y = 5
Step-by-step explanation:
Solving the above Equation given to us in the Question,
-x + y = 5...... Equation 1
x - 5y = 2....... Equation 2
Step 1
We make x subject of the formula in Equation 2
---> x= 5y + 2
Step 2
This would be to substitute 5y + 2 for x in Equation 1
-x + y = 5...... Equation 1
-(5y+2) + y = 5
Hence, Option A is the correct option

Answer: 24.8 and 155.2
Step-by-step explanation:
x+x+130.4=180
2x=49.6
x=24.8
Answer:
155.2
Step-by-step explanation:
let x be the supplimentary angle
then the angle is
130.4+x
we have
130.4+x+x=180
2x=49.6
multiply both sides with 2
x=24.8
then the angle is
130.4+24.8

A piano teacher charges $20 per lesson plus a $30 fee for supplies. Another
teacher does not have a supply fee but charges $30 per lesson. After how
many lessons will the cost of the two teachers be the same?
Answer:
3 Lessons
Step-by-step explanation:
Find out the difference between the initial price of each lesson. In this equation it's $10. With that being said, for every lesson the difference will always be $10. So the next lesson would be a $20 lesson and so forth. By the third lesson the difference would be $30. You add the $30 to the $30 per lesson teacher and you'll get $90 which would be equal to the teacher doing it for $30 an hour to begin with.
The total number of lessons when the cost of the two teachers be the same is 3 and this can be determined by forming the linear equation.
Given :
A piano teacher charges $20 per lesson plus a $30 fee for supplies. Another teacher does not have a supply fee but charges $30 per lesson.The following steps can be used in order to determine the total number of lessons will the cost of the two teachers be the same:
Step 1 - Let the total number of lessons be 'x'.
Step 2 - The total amount of money the first piano teacher earn is:
= 20x + 30
Step 3 - The total amount of money another piano teacher earn is:
= 30x
Step 4 - According to the given data, the cost of the two teachers be the same, that is:
20x + 30 = 30x
Step 5 - Simplify the above equation.
30 = 10x
x = 3

How many of the first million positive integers share no common factors greater than 1 with 2020
9514 1404 393
Answer:
396,040
Step-by-step explanation:
Factors of 2020 are 2, 5, 101.
There are 1,000,000 / 1010 = 990 multiples of 2 and 5 and 101.
There are 1,000,000 / 505 -990 = 990 multiples of 5 and 101 only.
There are 1,000,000 / 202 -990 = 3,960 multiples of 2 and 101 only.
There are 1,000,000 / 10 - 990 = 99,010 multiples of 2 and 5 only.
There are 1,000,000 / 101 -990 -990 -3960 = 3,960 multiples of 101 only.
There are 1,000,000 / 5 -990 -990 -99,010 = 99,010 multiples of 5 only.
There are 1,000,000 / 2 -990 -3960 -99,010 = 396,040 multiples of 2 only.
So, the total number of multiples of any factor of 2020 is ...
990 +990 +3960 +99,010 +3960 +99010 +396040 = 603960
Then the number of integers in the first million that do not share any common factors greater than 1 with 2020 is ...
1,000,000 -603,960 = 396,040

Please show working out
Answer:
Please Mark As Brainliest!!
834 and 799
Step-by-step explanation:
x+y=1633
x-y=35
2x= 1668
x=834
y=799
Answer:
((819.458,813.542)
Step-by-step explanation:
sum of two numbers=1633
x+y=1633----equation (i)
their difference=35
(x-y)^2=35----equation (ii)
solve simultaneous equation by using substitution method
x+y=1633
make x the subject of the formula
x=1633-y---(i)
substitute equation (i)into (ii)
(x-y)^2=3
(1633-y-y)^2=35
(1633-2y)^2=35
apply square root both sides
√(1633-2y)^2=√35
1633-2y=√35
-2y=√35-1633
-2y=-1627.08392
divide both sides by -2
y=813.5419601
substitute the value of y in equation (i
x=1633-y
x=1633-813.5419601
x=819.4580399
therefore the two numbers are (819.458, 813.542)
