In class A, 15 out of the 30 students are girls, and in class B, 24 out of the 40 students are girls. Which class has a higher percentage of girls?​

Answer:

0.80a + 0.95b

Step-by-step explanation:

They have given 2 different terms, which demonstrates the number of bananas and apples she may buy.

To find the total price we multiply the cost of one item with the number of items.

So the total cost for apples is 0.80 × a = 0.80a

And the total cost for bananas are 0.95 × b = 0.95b

Altogether, the amount will be: 0.80a + 0.95b

Answer:

25 yards

Step-by-step explanation:

A parallelogram is a quadrilateral (a four sided object) with parallel sides

Some of the characteristics of a parallelogram includes :

Area of a parallelogram = base x height

Area = 525

base = 21 yards

height = ?

525 = 21 x height

divide both sides of the equation by 21 to find the value of the height

525 / 21 = height

height = 25 yards

Answer:

   1/6

Step-by-step explanation:

The gradient of the line segment is the same as slope

m = (y2-y1)/(x2-x1)

   = ( -4 - -5)/( 2 - -4)

   = (-4+5)/( 2 +4)

   1/6

Answer:

Step-by-step explanation:

Gradient = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]

               [tex]=\frac{-4-[-5]}{2-[-4]}\\\\=\frac{-4+5}{2+4}\\\\=\frac{1}{6}[/tex]

The question is incomplete. The complete question is :

Nate starts a lawn-mowing business. In his business, he has expenses and revenue. Nate's expenses are the cost of the lawn mower and gas, and his revenue is $25 per lawn. At what point will Nate's revenue exceed his expense?

Cost of lawn mower = $ 200

Cost of gasoline = $ 2 per lawn

Solution :

Given :

Cost of the lawn mower = $ 200

The cost of gasoline expense for one lawn = $ 2

The revenue generated for one lawn = $ 25

So let the number of lawn to be mowed = x

Therefore the total expenses = [tex]$200+2x$[/tex]

So, the total revenue = [tex]$25x$[/tex]

The point for which the revenue will exceed the total expenditure will be :

[tex]$25x \geq 200+2x$[/tex]

So at [tex]x=9, \ 225 > 218[/tex]

Thus the revenue exceeds the total expenditure after mowing 9 number of lawns.

Answer:

For part a and b of this question

Step-by-step explanation:

x= # of lawns cut      y= total cost

revenue: y=25x

cost: y= -2x-200

He earns 25 per lawn, but loses $200 for his lawnmower and $2 per lawn.

b.  y=25x            y=-2x-200                    y=25x              

    y=-2x-200     25x=-2x-200                y=25(-7.40)

                              27x= -200                 y=-185

                                   x=-7.40

I believe this is correct.

Answer:

x= -9/4

Step-by-step explanation:

1) Isolate X

2) This will give you x+15x+4x=-21-24

(moving terms to another side will make it opposite, in this case positive 24 moving to the right will become negative 24)

3) Add the like terms

x+15x+4x = 20x

-21-24= -45

this will give you 20x=-45

4)Find the value of X by moving the 20 multiplier to the other side (this will become the opposite, division of 20)

x= -45/20

5) Simplify your answer

= -9/4

Answer:

65 degrees :)

Step-by-step explanation:

If you have 115 degrees, and you know triangles are always 180 degrees in total, then you have to subtract 115 from 180 to get your answer for what the measures are. 180-115=65

So  it's 65 degrees.

I think this is what you want to know :)

Answer:

6/7

Step-by-step explanation:

so, here's the thing ,the product of the slopes of perpendicular lines when multiplied must be equal to -1. So in this situation ,first find the slope of the line that passes through the given points like this :

m = y2 - y1 / x2- x1 (formula for the slope)

m= 7 - 0 / 3- 9

m=7 /-6

now you can find the perpendicular slope like this

m1 * m2= -1. (m1 = 7/-6)

7/-6 *m2=-1

m2 = 6/7

Answer:

The discriminant of the quadratic equation is 0

Step-by-step explanation:

Here, we want to calculate the discriminant of the given quadratic equation

Mathematically, we have the discriminant calculated by the following formula;

D = b^2 - 4ac

where;

b represents the coefficient of x which is -2

a is the coefficient of x^2 which is 1/7

c is the last number which is 7

Substituting these values;

D = (-2)^2 -4(1/7)(7)

D = 4 - 4

D = 0

1. They will meet as 7:20 PM

explanation: The first friend runs at a speed of 8 miles per hour.

The second friend runs at a speed of 7 miles per hour.

they left at 6 p.m.

their houses are 20 miles apart,

Since they are running towards each other the effective speed will be

(8+7) = 15 mph

Distance = 20 miles

time they run = 20/15 =4/3 hours

They will meet at 7:20 pm
