So, the question on my test was a pair of in line skates is on sale for 90. if this price represents a 9% discount from the original price, what is the original price to the nearest cent. My teacher got 98.90, but i got 98.10. which is mathematically correct?

Answer:

the answer would be 11 hours and 25 minutes

Step-by-step explanation:

Answer:

4.42 hours

The reason why is by adding, 8:45 can round up to 9, and 1:10 can round down to 1, this make it simpler. 8:45+15 1:10-10

9AM to 1PM

9AM+3=12PM, add 1 and you get 1 pm=4 hrs, add 15+10, and you get somewhere close to it.

Answer:

x = - 6

Step-by-step explanation:

A line with a slope of zero is a horizontal line parallel to the x- axis with equation

x = c ( where c is the value of the x- coordinates the line passes through )

The line passes through (- 6, - 7 ) with x- coordinate - 6 , then

x = - 6 ← equation of line

Answer:

The answer I think, might be or possibly is A 20 aq ft. Bcuz, if you use the 1:4 scale, you'll get like for an example, 20:80..So, 5:? must be 5:20..get what I mean??? it's kinda tuff for me to explain since English is not my first language but thereee you go XD

it would be the second one because it is exactly the same the first one is a little bit shorter so there not exactly the same

Answer:

g(x)=3

Step-by-step explanation:

Answer:

26

Step-by-step explanation:

g(x) = 3x-1

f(x)= x+5

g(f(4)

plug 4 into f

f(4)

now apply x+5

f(4)=4+5=9

plug 9 into g

g(9)

now apply 3x-1

g(9)=3(9)-1

3 ×9= 27

27-1=26

hence the answer is 26

Answer:

x = 6

Step-by-step explanation:

110 and 19x - 4 are alternate exterior angles and are congruent, then

19x - 4 = 110 ( add 4 to both sides )

19x = 114 ( divide both sides by 19 )

x = 6

Answer:

can you give me points ??

Answer:

Step-by-step explanation:

first put 6:4

6 is 3 by 2

4 is 2 by 2

the 2 in 4 and 6 is gone

so we will have in the 6 3 left and in the 4 2 left

so what is 3 by 2

Answer:

3. W=4, L=10

4. W=4, L=8

Step-by-step explanation:

3.

L = 3W-2

W = W

P = 2L + 2W

P = 2(3W-2)+2W

P=28

2(3W-2)+2W=28

8W-4=28

8W=32

W=4

L=3W-2, or 10

Check: 2(4)+2(10) = 28? Yes

4.

L=2W

W=W

P=24

2L+2W=24

2(2W)+2W=24

6W=24

W=4

L=8

Check: 2(8)+2(4)=24 ? 16+8 = 24 Yes

Queremos ver que fracción de la finca se ha destinado a plazas de aparcamiento.

La solución es:

La fracción de la finca que se destina a plaas de aparcamiento es 3/56

Sabemos que originalmente se iba a destinar 3/14 del total de la finca a plazas de aparcamiento, pero finalmente se destino 3/4 de lo previsto a zonas ajardinadas.

Es decir, se destino 3/4 de los 3/14 del total de la finca a zonas ajardinadas, entonces el 1/4 restante se dedico a plazas de aparcamiento, esto da:

(1/4)*3/14  = 3/56

La fracción de la finca que se destina a plaas de aparcamiento es 3/56

Answer:

$306

Step-by-step explanation:

Adult cost = no of adult × adult cost

no of adult = 12

adult tickets cost = $8

= 12 x $8

= $96

kids cost = no of kids x kids tickets cost

no of kids = 42

kids tickets cost = $5

= 42 x $5

= $210

total sales for the theatre =$96 +$210

= $306

Answer:

41 inches of wire will cost 164 cents.

Step-by-step explanation:

1st Method

Use proportions!

18/ 72 = 41/ c

Cross multiply

18 * c = 72 * 41

18c = 2952 divide both sides by 18

c = 164

2nd Method.

Find the rate of the costs. r = rate

18*r = 72

r = 4 cents/inch

Now that you've found the rate you can multiply it by 41 inches to find the cents the wire costs!

41 inch * r (cents/inch)          inches cancels out.

41 * 4 = 164

164 cents

Answer:

y-1= -3/4(x-1)

Step-by-step explanation:

find the slope then put it in the format: y2-y1=m(x2-x1)

y-1= -3/4(x-1)

Answer:

y = -3/4x + 7/4

Step-by-step explanation:

So we have 2 points:

(-3, 4) & (1, 1)

The formula for point-slope is:

y - y1 = m (x - x1)

First, we need to find the slope between the points

The formula for this is

(y2 - y1) /(x2 - x1)

1 - 4 / 1 - (-3) ->

-3 / 4

Our slope is -3/4 (m)

y = -3/4 (x + 3) + 4

I've done this using a simplified formula for point slope which is

y = m(x - x1) + y1

we can simplify this equation more

y = -3/4x + 7/4

is our final equation.

Answer:

135 onions

Step-by-step explanation:

bc

7 1/2 = 15/2

15/2 x 3 = 45/2

45/2 = 22.5

bc its only 1 of 6 pieces, you have to multiply 22.5 by 6

22.6 x 6 = 135

Answer: 9

Step-by-step explanation:

-3 1/3 x (-2 7/10)

-3  = -3*(3/3) = -9/3

-3 1/3 = -10/3

(-2 7/10)

-2  = -2(10/10) = -20/10

-2 7/10 = -27/10

(-10/3)*(-27/10) = (270/30) = 9
