Answer:

[tex]Persephone = 27\frac{3}{7}[/tex]

[tex]Madison = 20\frac{4}{7}[/tex]

Step-by-step explanation:

Given

[tex]Pages = 48[/tex]

[tex]P=8\ mins[/tex] --- Persephone

[tex]M = 6\ mins[/tex] --- Madison

The question is incomplete, however a possible question could be:

To determine the number of pages colored by each of them

First, we determine the ratio of time spent by each:

[tex]P : M = 8 : 6[/tex]

The number of pages covered by Persephone is:

[tex]Persephone = \frac{P}{P + M} * Pages[/tex]

[tex]Persephone = \frac{8}{8+6} * 48[/tex]

[tex]Persephone = \frac{8}{14} * 48[/tex]

[tex]Persephone = \frac{384}{14}[/tex]

Simplify

[tex]Persephone = 27\frac{3}{7}[/tex]

This implies that Madison colors the remaining pages.

This is calculated as:

[tex]Madison = Pages - Persephone[/tex]

[tex]Madison = 48 - \frac{384}{14}[/tex]

Take LCM

[tex]Madison = \frac{48 * 14 - 384}{14}[/tex]

[tex]Madison = \frac{288}{14}[/tex]

Simplify

[tex]Madison = 20\frac{4}{7}[/tex]

Answer:

The volume of the space for each drawer is 6 feet^3.

Step-by-step explanation:

Solve for the volume of the entire dresser.

Formula for volume of a rectangle:

Volume (v) = Length (l) × width (w) × height (h)

v = 2 × 6 × 3

v = 12 × 3

v = 36

Now divide the volume by the number of drawers.

36 ÷ 6 = 6

Answer: x=30°

Step-by-step explanation:

A parallelogram always add up to 360°.

Opposite angles like F and H are always the same, so H=150°.

150+150=300 (what angles F and H add up to)

So we can do:

360-300=60

Now we know that the angle x and E have to add up to 60 but still be the same, so x will equal 30°.

We can check this by adding up all of the sides:

150+150+30+30=360°

Hope this helped :)

Answer:

1 in 10, or 10% because there is a 90% chance she will choose the wrong number.

Answer:

[tex]\frac{1}{10}[/tex]

Step-by-step explanation:

1-10 is 10 numbers, only one of which is the correct one.

The resulting proportion is:

[tex]\frac{1}{10}[/tex]

Answer:

Let me get my homie on here to help you.

Step-by-step explanation:

Step-by-step explanation:

Given

Circumference of circle = 48.042 yards

diameter (d) = ?

we know

Circumference = πd

or, 48.042 = 3.14 * d

or, d = 48.042 / 3.14

Therefore d = 15.3 yards

The circle's diameter is 15.3 yards.

Hope it will help :)❤

Answer:

(3, 0 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c (a ≠ 0 )

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

y = 5x² - 30x + 45 ← is in standard form

with a = 5, b = - 30 , then

[tex]x_{vertex}[/tex] = - [tex]\frac{-30}{10}[/tex] = 3

Substitute x = 3 into the function for corresponding value of y

y = 5(3)² - 30(3) + 45 = 45 - 90 + 45 = 0

vertex = (3, 0 )

Answer:

Vertex is (3,0)

Step-by-step explanation:

Given y= 5x^2 - 30x + 45

         y    = 5 ( x^2 - 6x + 9)

               = 5 ( x -3 )^ 2 + 0

Standard formula of parabola is y = a(x - k)^2 + k where vertex is (h,k)

Here, h = 3 and k = 0

So,  Vertex is ( 3, 0)

Answer:

It can be the line of best fit because it is closest to most of the data points.

Answer:

1: 45

2: 32

3: 35

4: 32

Step-by-step explanation:

when finding the area of a trapezium you can also just split the rectangle and triangle to have 2 different areas then combine to have the same area. but also this would be more difficult if you needed to separate the trapezium into more than 3 shapes.

so if there is like a trapezoid that you split and there is a rectangle and 2 triangles it is harder than doing the formula.

so use the formula sometimes too if it is easier.

Answer:

1 would be 45, 2 would be 32, 3 would be 35, 4 would be 32

Answer: 9.21954

it’s pythagorean theorem btw :)

Answer:

5 and 7

Step-by-step explanation:

Let the two numbers be x and x + 2.

According to Question ,

[tex]\implies x + x + 2 = 12 \\\\\implies 2x = 12 -2 \\\\\implies 2x = 10 \\\\\implies x =\dfrac{10}{2}\\\\\implies\boxed{ x = 5 }[/tex]

Hence the nos . are 5 and 7

Answer:

2 miles

Step-by-step explanation:

12 mph would be 6 miles in a half hour

8 - 6 = 2 miles

Answer:

8 cm

Step-by-step explanation:

The formula of circumference is c= πd------(1)

where C = circumference, π = 3.14 and d = diameter

as we know that diameter is equal to d= 2r

put the diameter formula in eq(1)

we get c= π2r-------(2)

from eq (2) separate r means radius

hence, r= c/(π2)------(3)

put the values in eq(3)

and radius is equal to 8 cm.

Multiplying N by what he makes for each one and add to his salary:

P = 70N + 2200

Replace n with 26 and solve:

P = 70(26) + 2200

P = 1820 + 2200

P = 4020

He earns $4,020
