Answer:
percentage of increase = 49%
Step-by-step explanation:
Percentage change for any value is given by
percentage change = (new value - old value)/old value * 100 %
If there is increase in new value, percentage change can be called as percentage increase.
If there is decrease in new value, percentage change can be called as decrease increase.

Distance covered in first half of game = 50.5 yards
Distance covered in first full game = 75 yards
percentage of increase = (Distance covered in first full game - Distance covered in first half of game)/Distance covered in first half of game * 100 %
percentage of increase = (75 - 50.5)/50.5 * 100% = 24.5/50 * 100%
percentage of increase = 49% answer

what does x equal 8x−2=12x+18
Answer:
x = -5
Step-by-step explanation:
Start by combining terms.
8x-2 = 12x +18
8x -12x = 18+2
-4x = 20
*Divide both sides by -4
x = -5
Point J located at (2, 7) is rotated 90 degrees counterclockwise about (-1, -3). What is the y-coordinate of J’?
A. 9
B. 0
C. -11
D. -9
Given:
Coordinates of point J are J(2,7).
It is rotated 90 degrees counterclockwise about (-1, -3).
To find:
The y-coordinate of J’.
Solution:
If a figure rotated 90 degrees counterclockwise about a point (a,b), then
[tex](x,y)\to (-(y-b)+a,(x-a)+b)[/tex]
Point J is rotated 90 degrees counterclockwise about (-1, -3). So, a=-1 and b=-3.
[tex](x,y)\to (-(y-(-3))+(-1),(x-(-1))+(-3))[/tex]
[tex](x,y)\to (-(y+3)-1,(x+1)-3)[/tex]
[tex](x,y)\to (-y-3-1,x+1-3)[/tex]
[tex](x,y)\to (-y-4,x-2)[/tex]
Coordinates of point J are J(2,7).
[tex]J(2,7)\to J'(-7-4,2-2)[/tex]
[tex]J(2,7)\to J'(-11,0)[/tex]
Therefore, the y-coordinate of J' is 0. Hence, the correct option is B.

How do you make the yellow "First answer" on your questions??????????? it looks like the thing below.
This tag only appears on a user's question when it's their first question on the site.
If x = 1, what is the value of y given 2x + 2y = 18?
Answer:
y=8
Step-by-step explanation:
2(1)+2y=18
2+2y=18
minus 2 from both sides
2y=16
divide by 2 from both sides
y=8
Answer:
y=8
Step-by-step explanation:
1. If x is equal to 1, 2x is just 2.
2. We can subtract the 2 we already have. 18-2=16
3. 2y=16, divide by 2 on both sides.
y=8

A theater is tracking the number of adults and children in the audience at
various shows. The table shows how the number of adults and children
are related
Select the equation that matches the relationship.
X+y = 1000
X-y1000
y-x= 1000
Y= 1000xc
Adults
Children
500
500
450
550
400
600
350
650 I Need help i dont understand!!!!!!!!
Answer:
The correct option is;
x + y = 1000
Step-by-step explanation:
The data from the table can be presented as follows
Adults (x) [tex]{}[/tex] Children (y)
500 [tex]{}[/tex] 500
450 [tex]{}[/tex] 550
400 [tex]{}[/tex] 600
350 [tex]{}[/tex] 650
Therefore, we have the rate of change of the children, y to the adults, x, which is also the slope of the graph of the data given as follows;
The slope, m = dy/dx = (650 - 500)/(350 - 500) = 150/(-150) = -1
m = -1
The function of the graph in point and slope form, using the first point, becomes;
y - 500 = -1 × (x - 500) = -x + 500
∴ y - 500 = -x + 500
y + x = 500 + 500 = 1,000
Which gives
y + x = 1,000
y + x = x + y = 1,000

Ms. Granger gave the cashier $20 to pay for 3 bags of Halloween candy. The cashier gave her $5.24 in change. Each bag cost the same amount. What is the cost in dollars and cents for each bag of candy?
Answer:
$4.92 per bag
Step-by-step explanation:
20 - 5.24= 14.76
14.76 divided by 3 = 4.92
If the discriminant of a quadratic equation is 8, which statement describes the roots?
O There are two complex roots.
O There are two real roots.
O There is one real root.
O There is one complex root.
Answer:
There are two real roots
Step-by-step explanation:
From the value of the discriminant b² - 4ac
• If b² - 4ac > 0 then 2 real and distinct roots
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then 2 complex roots
Here b² - 4ac = 8 > 0 , then there are two real roots
20 p − 4 ( 3 p − 6 ) = 8 ( 3 p − 6 ) − 16 p
Give steps to please !!!!
Answer:
5.5
Step-by-step explanation:
20p-4(3p-6)=8(3p-6)-16
20p-12p+24=24p-48-16
8p+24=24p-64
+64 on both sides
8p+88=24p
-8p on both sides
88=16p
/16 on both sides
answer = 5.5
Last week, Kimi spent $181.91 at the grocery store on Monday. Then she spent another $186.40 on Friday. How much did Kimi spend at the grocery store last week?
Answer:
$368.31

Jane contribuyó con $ 10,000 y Julie contribuyó con $ 6,000. Después de un año, la empresa obtuvo una ganancia de $ 4,000. ¿Qué proporción de las ganancias debería tomar Julie si se comparten en la misma proporción que sus contribuciones originales?
Answer:
Ganancias Julie= $1,500
Step-by-step explanation:
Dada la sigueinte información:
Jane contribuyó con $ 10,000 y Julie contribuyó con $ 6,000. Después de un año, la empresa obtuvo una ganancia de $ 4,000.
Primero, debemos calcular la proporción de aportes de cada una:
Jane= 10,000/16,000= 0.625
Julie= 6,000/16,000= 0.375
Ahora, lo que le corresponde a Julie de las ganancias:
Ganancias= 4,000*0.0375
Ganancias Julie= $1,500

The points (6,r) and (9, 9) lie on a line with slope 5. Find the missing coordinate r.
Answer:
r = -6
Step-by-step explanation:
Use the slope formula and solve for r.
slope = y2 -y1
x2 -x1
Since you know all the numbers except for r, plug everything in and you get:
5 = 9 - r
9 - 6
So then do the arithmetic, you find that 9 - r = 15. So r must = -6.
Solve for x with given angle measures.
Answer:
Step-by-step exx=3planation:
The exterior angle is equal to the sum of the opposite interior angles
3x^2 -6x+8x = 2x^2 +3x+6
Combine like terms
3x^2+2x=2x^2+3x+6
Subtract 2x^2 from each side
3x^2+2x -2x^2=2x^2-2x^2+3x+6
x^2+2x=3x+6
Subtract 3x from each side
x^2+2x-3x=3x-3x+6
x^2-x=6
Subtract 6 from each side
x^2 -x-6 =0
Factor
( x-3)(x+2) =0
Using the zero product property
x-3 =0 x+2 =0
x=3 x=-2
But x cannot be negative since an angle would have a negative value so
x=3
Check
3x^2 -6x+8x = 2x^2 +3x+6
3 ( 3)^2 -6(3) +8(3) = 2 (3)^2 +3(3)+6
3*9 -18 +24 = 2 *9 +9+6
27 -18+24 = 18+9+6
33=33

the answer is JKN = 57
Step-by-step explanation:
JKN is JKL + LKN
we know that LKM = 42, and LKN is half of that because KN bisects LKM (splits into 2 equal parts)
so, LKN is half of 42
LKN = 21
to find JKL, subtract 42 from 78
JKL = 36
36 + 21 = 57
