Answer 1

Answer:

Step-by-step explanation:

(4)(3) = 12

x^3(x^[-5]) = x^(3 - 5) = x^(-2)

                                                                                                          12

Combining these in multiplication we get the final answer    ------------

Answers

Answer:

y = 50°, x =50°

Step-by-step explanation:

y + 70 + 60 = 180° .......straight line has 180°

y = 180° - 60° -70° =50°

x = y.......here vertical angles are always equal. So,

x = 50°

Answer:

y = 50°, x =50°

Step-by-step explanation:

y + 70 + 60 = 180° .......straight line has 180°

y = 180° - 60° -70° =50°

x = y.......here vertical angles are always equal. So,

There are x students in Mrs. Schwartz's third-grade class. One fewer than half the students have brown eyes. Six fewer children have blue eyes than have brown eyes. The rest of the students have green eyes. How many students have green eyes?


F. 8
E. 7
G. x/2-7
H. x - 8

Answers

Brown Eyes: 1/2x - 1
Blue Eyes: 1/2x-6

Let the students who have green eyes be y.

1/2x-1+1/2x-6= x-y (Because the RHS is the students with brown and blue eyes and hence x-y on the LHS)
x-7=x-y
-y=-7
y=7

Therefore 7 students have green eyes.

Answer:

See below

Step-by-step explanation:

Part A

Standard form is Ax + By = C

x - price of adult tickets, y - price of child tickets, the equation in the standard form is:

15x + 9y = 90 ⇒ 5x + 3y = 30Part B

y-intercept is obtained when x = 0

15*0 + 9y = 909y = 90y = 10

It represents the amount of child tickets if no adult tickets sold

x-intercept is obtained when y = 0

15x + y*0 = 9015x = 90x = 6

It represents the amount of adult tickets if no child tickets sold

Part C

Converting the equation into slope-intercept form of y = mx + b

5x + 3y = 303y = -5x +  30y = -5/3x + 30/3y = -5/3x + 10Part DThe slope is -5/3. It represents the negative ratio of ticket prices

Of the students at Milton Middle School, 216 are girls. If 60% of the students are girls, how many total students are there at Milton Middle school?

you will be the brainliest

Answers

Answer:

360

Step-by-step explanation:

x*60/100=216

60x=21600

x=21600/60

x=360

Answer:

360 students are thee in Milton Middle School.

Step-by-step explanation:

Number of girls in Milton Middle School = 216

Percentage of girls in Milton Middle School = 60%

From the above information we can know that 216 = 60% of Milton Middle School.

1% of students in the school = 216/60

                                                 = 3.6

100% of students in the school = 3.6 * 100

                                                      = 360 students


                                      Or

Total number of students in Milton Middle School = 216/60 * 100

                                                                                       = 216/6 * 10

                                                                                       = 36 * 10

                                                                                        = 360 students

Answer:

Step-by-step explanation:

You want to know the difference in miles per hour between a satellite traveling 45000 miles in 5 hours and one traveling 79200 miles in 18 hours.

Miles per hour

The speed in miles per hour is the ratio of miles to corresponding hours. The difference in miles traveled in one hour will be ...

  A speed - B speed

  45000 mi/(5 h) - 79200 mi/(18 h) = 4600 mi/h

Explorer B travels 4600 fewer miles in an hour than Explorer A.

Answers

Answer:

D. 36.9

Explanation:

three-fifths of 61.5 is 36.9!

Answer:

D. 36.9

Step-by-step explanation:

The total amount of gallons the gardener typically uses in a month is 61.5 gallons. Since the gardener used 3/5 gallons, we know that 5/5 is 61.5 gallons. So you would have to divide 61.5 by 5 in order to get 1/5 of the gallons which would be 12.3. Then you have to multiply the 12.3 by 3 in order to get 3/5 of how much the gardener used which is 39.9 gallons. I hope this helped!
