The answer is D because all you need to do is multiply everything by 0.5, or one half.

Aidan's average speed on his drive home is 26 2/3 miles per hour

Average speed is the total distance travelled per time. It indicates how fast an object is moving.

Average speed = total distance / total time

The first step is to determine the time it would take Aidan to drive to school :

Time = distance / speed

16 / 40 = 2/5 hours = 2/5 x 60 = 24 minutes

The second step is to determine the time it would take Aidan to drive from school

Time it would take to drive home from school = 60 minutes - 24 minutes = 36 minutes = 36/60 = 3/5 hours

Aidan's average speed to drive home = 16 miles ÷ 3/5

16 x 5/3 = 80 / 3 = 26 2/3 miles per hour

Step-by-step explanation:

Step 1: Define Equation

2x + 10 = -4x - 9

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 11/3 does indeed equal 11/3.

∴ x = -19/6 is the solution to the equation.

divide 162 by 200

Answer:

$160

Step-by-step explanation:

Step one:

It costs $100 to rent the bowling alley

plus $4 per person

the expression for the cost is

[tex]C=100 + 4n[/tex]

where n is the number of people

for n= 15

Step two:

let us substitute

[tex]C= 100+4(15)\\\\C= 100+60\\\\C= 160[/tex]

===========================================

Work Shown:

t = x³

f(x) = 1 + 12x³ + 3x⁶

f(x) = 1 + 12x³ + 3(x³)²

f(t) = 1 + 12t + 3t²

f(t) = 3t² + 12t + 1

f(t) = 3(t² + 4t) + 1

f(t) = 3(t² + 4t + 4 - 4) + 1 .... see note below

f(t) = 3( (t²+4t+4) - 4) + 1

f(t) = 3( (t+2)² - 4) + 1

f(t) = 3(t+2)² - 3*4 + 1

f(t) = 3(t+2)² - 12 + 1

f(t) = 3(t+2)² - 11

The smallest that t² can get is 0. By extension, the smallest (t+2)² can get is also 0, and same goes for 3(t+2)².

So effectively we replace the 3(t+2)² portion with 0 and end up with  3(t+2)²-11 = 0-11 = -11 as the minimum value of f(x)

This is the smallest output possible. Confirmation of such is shown in the  graph below.

------------

Note: Recall that (A+B)² = A²+2AB+B². If we use this rule on (t+2)², then we get t²+4t+4. Earlier we simply had t²+4t without the extra +4 at the end. So I added 4 and subtracted 4 to balance things out. This completed the square.

Answer:

The equation in the slope-intercept form will be:

y  = 1/4x - 7

Step-by-step explanation:

Given the points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-4,\:-8\right),\:\left(x_2,\:y_2\right)=\left(-8,\:-9\right)[/tex]

[tex]m=\frac{-9-\left(-8\right)}{-8-\left(-4\right)}[/tex]

[tex]m=\frac{1}{4}[/tex]

We know that the slope-intercept of line equation is

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

substituting m = 1/4 and the point (-4, -8) to find the y-intercept 'b'

y = mx+b

-8 = 1/4(-4)+b

-8 = -1 + b

b = -8+1

b = -7

so the y-intercept = b = -7

substituting m = 1/4 and b = -7 in the slope-intercept form of line equation

y = mx+b

y  = 1/4x + (-7)

y  = 1/4x - 7

Thus, the the equation in slope-intercept form will be:

y  = 1/4x - 7

Answer:

The answer is C.

Step-by-step explanation:

In order to find the x-intercept and y-intercept, you have to substitute 0 into each expression :

[tex]let \: x = 0[/tex]

[tex]0 - 3y = 6[/tex]

[tex] - 3y = 6[/tex]

[tex]y = 6 \div ( - 3)[/tex]

[tex]y = - 2[/tex]

[tex]let \: y = 0[/tex]

[tex]2x - 0 = 6[/tex]

[tex]2x = 6[/tex]

[tex]x = 6 \div 2[/tex]

[tex]x = 3[/tex]

Given that the x-intercept is 3 and y-intercept is -2. By looking at the picture, graph C fits the coordinates, (3,0) and (0,-2).

Answer: it’s 8 to 14 number c

Step-by-step explanation:

Let me know if I’m wrong

The ratio equivalent to 20 to 35 is 8 to 14.

Option C is the correct answer.

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

20 to 35

This can be written as,

= 20/35

= 5 x 4 / 5 x 7

= 4/7

Now,

5 to 7 = 5/7

7 to 5 = 7/5

8 to 14 = 8/14 = 4/7

14 to 8 = 14/8 = 7/4

Thus,

20 to 35 is the same as 8 to 14.

Answer:

23.41 feet

Step-by-step explanation:

The ladder forms a right angle triangle with the wall

Height of the wall (opposite) = 22 feet

Bottom of the ladder from the wall (adjacent) = 8 feet

What is the length of the ladder?

Length of the ladder (hypotenuse)

Using Pythagoras theorem

Hypotenuse ² = opposite ² + adjacent ²

= 22² + 8²

= 484 + 64

= 548

Hypotenuse ² = 548

Hypotenuse = √548

= 23.41 feet

The length of the ladder is 23.41 feet

To cover a floor with an area of 10 square foot, 5 tiles is needed.

Area is the amount of space enclosed by a two-dimensional figure.

If the tile is 2 feet long and twice as long as they are wide, suppose that the tile is a rectangle, then the area of each tile will be:

Area of tile = l x w

where l = 2 feet

w = 1 foot

Area of tile = 2feet(1 foot)

Area of tile = 2 ft^2

To determine how many tiles are needed to cover a 10 foot square floor, divide the area of the floor with the area of each tile.

# of tiles = Area of floor/Area of each tile

# of tiles = 10 ft^2/2ft^2

# of tiles = 5

1  21/50

The number 142 % in mixed number form is 1 21/50

What are Mixed Numbers?

A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.

Given data ,

The number given is = 142 %

On simplifying , we get

142 % = 100 % + 42%

We know that 100 % = 1

So ,

42 % = 42 / 100

Divide by 2 on both numerator and denominator , we get

21 / 50

So , the number 142 % is written as 1 21/50

Or ,

Simplifying 142 / 100 , we get

142 / 100 = 71 / 50

Converting 71 / 50 into mixed number , we get 21 as the remainder ,

Therefore , the mixed number form of 71 / 50 is 1 21/50

Hence , the mixed number form is 1 21/50

Answer:

Scale factor: 2

PR = 14

Perimeter = 34

Step-by-step explanation:

Similar Triangles

Similar triangles are those who have their corresponding side lengths proportional, i.e. the ratio of the corresponding sides is equal.

The figure shows similar triangles ABC and PQR. We can also see corresponding sides BC and QR have lengths 6 and 12 respectively.

The scale factor is [tex]\frac{12}{6}=2.[/tex]

The rest of the sides can be calculated by using the per-image triangle ABC side lengths and the new-found scale factor. Thus:

PR = AC*2 = 7*2 = 14

PR = 14

PQ = AB*2 = 4*2 = 8

The perimeter of the triangle PRQ is the sum of its side lengths:

P = 12 + 14 + 8 = 34
