The number of rotations for the new wheel will be  1,056 rotations

Let the initial circumference be 50 rotations  (assumed)

If the number of rotations of the circumference of the tires were increased by 20%, then the new circumference will be:

Ne circumference = 1.2 * 50 = 60

number of rotations for the new wheel = 63360/60
number of rotations for the new wheel = 1,056 rotations

Hence the number of rotations for the new wheel will be  1,056 rotations

Answer:

c) 2 2/3 times greater

Step-by-step explanation:

The length of the rectangle:

The width of the rectangle is x. If you add the two widths together when finding perimeter, x + x, that would give you 2x.

Sum of widths: x + x = 2x

Use the sum of the widths to find the sum of the lengths by subtracting from the perimeter.

sum of lengths = perimeter - sum of widths

8x - 2x = 6x

Since there are 2 lengths divide by 2.

6x/2 = 3x

The length of the rectangle is 3x

Perimeter of the square:

The sides of the square are 1/4 of the length of the rectangle. "of" means to mulitply: (I made 3x a fraction by placing it over 1)

[tex]\frac{1}{4} (\frac{3x}{1} )[/tex] = [tex]\frac{3}{4} x[/tex]

Now find the perimeter of the square by multiplying the side length by 4.

[tex]\frac{3}{4}x(\frac{4}{1} )[/tex] = [tex]3x[/tex]

Last part:

solve the rectangle's perimeter by substituting x with 4.

P = 8x

P = 8(4)

P = 32 cm

Solve the square's perimeter by substituting x with 4.

P = 3x

P = 3(4)

P = 12 cm

Divide the rectangle's perimeter by the square's perimeter.

32/12 = 2 2/3 times bigger.

Answer:

-1

Step-by-step explanation:

-100x-100=0

-100x=100

x/-100=100/-100

x=-1

When you are solving for a variable your goal is to get the variable by it seff.

x = -1

- 100x = 100

Step-by-step explanation:

[tex] - 100x - 100 = 0[/tex]

Move the constant to the right side and change the sign

[tex] - 100x = 100[/tex]

Change the sign of both side of the equation

[tex]100x = - 100[/tex]

Divide both side by the same number

[tex]x = - 1[/tex]

[tex] - 100x[/tex]

[tex] - 100 \times - 1[/tex]

Remove the ( - ) sign since negative number are multiplied by even number...

Answer:

False, it would actually be 106 beads. If this was a multiplication problem, that would also be false, because 6 times 100 is 600, not 350.

But let's attempt to make this statement true.

First/Last step: Find the missing beads.

The missing beads are 144.

Why?

Because you must add 144 to reach 250, there is no other way but to multiply. In this case, because the key word is, "In all" we are adding.

Given system of equations

Substitute the value of y into second equation

Solve for x

Find the value of y

Answer:

(-5, 9)

Step-by-step explanation:

Given system of linear equations:

[tex]\begin{cases}-2x-y=1\\-4x-y=11\end{cases}[/tex]

To solve by substitution, use arithmetic operations to isolate y in Equation 1:

[tex]\implies -2x-y=1[/tex]

[tex]\implies -2x-y+y=1+y[/tex]

[tex]\implies -2x=1+y[/tex]

[tex]\implies -2x-1=1+y-1[/tex]

[tex]\implies y=-2x-1[/tex]

Substitute the expression for y into Equation 2 and solve for x:

[tex]\implies -4x-(-2x-1)=11[/tex]

[tex]\implies -4x+2x+1=11[/tex]

[tex]\implies -2x+1=11[/tex]

[tex]\implies -2x+1-1=11-1[/tex]

[tex]\implies -2x=10[/tex]

[tex]\implies -2x \div -2=10 \div -2[/tex]

[tex]\implies x=-5[/tex]

Substitute the found value of x into one of the equations and solve for y:

[tex]\implies -2(-5)-y=1[/tex]

[tex]\implies 10-y=1[/tex]

[tex]\implies 10-y+y=1+y[/tex]

[tex]\implies 10=1+y[/tex]

[tex]\implies 10-1=1+y-1[/tex]

[tex]\implies y=9[/tex]

Therefore, the solution to the given system of linear equations is (-5, 9).

The inequality of the graph is a linear inequality

The inequality shown in the graph is y > -2x -2

The points on the graph are given as:

(x,y) = (-2,2) and (0,-2)

The slope (m) is calculatedusing:

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

This gives

m =(-2 - 2)/(0 + 2)

Evaluate

m = -2

The equation is then calculated as:

y = m(x - x1) + y1

This gives

y = -2(x - 0) -2

y = -2x -2

The upper part of the graph is shaded with a dotted line, so the inequality is a greater than inequality

The equation becomes

y > -2x -2

Hence, the inequality shown in the graph is y > -2x -2
