The quantities x and y are proportional.

Answer:

a

Step-by-step explanation:

step 1: simplify the expression (parentheses)

2 (-2 - 4p) + 2 (-2p - 1)

-4 - 8p + -4p - 2

step 2: add similar number together

-6 - 12p

Answer: These lines are perpendicular

Step-by-step explanation:

Let's use slope intercept form, y=mx+b (m=slope, b=y intercept)

Parallel lines have the same slope, or m

Perpendicular lines have an opposite reciprocal slope

y=-2x+1 is already in slope intercept form. Let's change the other problem

Here are the two problems: y=-2x+1 and y=1/2x+5/4

Look closer. These lines are actually perpendicular.

Take the second problem's slope, 1/2. Make it a negative reciprocal, which means -2/1 or -2. These lines are perpendicular.

Answer:

n = -7/2

Step-by-step explanation:

2(n - 3) = 4n + 1

=> 2n - 6 = 4n + 1

=> -6 - 1 = 4n - 2n

=> -7 = 2n

=> n = -7/2

As per the graph, the time it takes for the person riding the ferris wheel to make a complete revolution is typically 60 seconds.

When the ferris wheel starts, the height of the red car will initially increase as it ascends from the ground level. As the ferris wheel continues to turn, the red car will reach its maximum height, usually at the topmost position of the ferris wheel, and then descend back to the ground level. This motion will repeat as the ferris wheel continues to rotate.

Now, let's determine how long it takes for the person riding the ferris wheel to make a complete revolution. One revolution corresponds to the time it takes for the ferris wheel to complete one full cycle of motion, going from its initial position, through its highest point, and back to its initial position. This time can be calculated by finding the time period of the sinusoidal function representing the height of the red car.

To find the time period, we need to know the duration for one complete cycle of the sine wave, which is the time it takes for the ferris wheel to complete one revolution. The time period can be derived from the angular speed of the ferris wheel. If we know the angular speed (usually given in rotations per minute or radians per second), we can calculate the time it takes for one revolution.

Answer: 14.13

Step-by-step explanation:

Your answer is 14.13

First, the formula for area of a semi circle is 3.14 x r^2 and divide by two.

To find the radius, we need to divide the diameter by two, which is 3.

So like

3.14 x 3^2/2

3.14 x 9/2

28.26/2

A=14.13

Answer:

14.13

Step-by-step explanation:

normal circle area equation = r^2*3.14

6/2=3

3*3*3.14

= 28.26

it's a semicircle so /2

=14.13

Answer:

First, we know that:

1 1/3 = 4/3

10 2/3 = 32/3

15 minutes = 0.25 hours

Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.

From the information, we can tell that:

Lee can type:

4/3 pages in 0.25 hours

32/4 pages in x hours

So x should be:

x = (32/4 . 0.25)/4/3 = 2 (hours)

So it takes Lee 2 hours ro type 10 2/3 pages

-4(-2x + 5) + 2x + 3 =-11

Distribute

8x-20 +2x+3 = -11

Combine like terms

10x-17 = -11

Add 17 to each side

10x-17+17 = -11+17

10x =6

Divide by 10

10x/10 = 6/10

Answer:

2b + 42 = 134 —> Opposite angles

2b= 134 – 42

2b= 92

b= 92/2

(2b+42) = 2(46)+42 = 92 +42= 134°

134 + (3a+4) =180

134+3a+4=180

3a+138=180

3a= 180 – 138

3a = 42
