You and your sister help your neighbor rake their lawn. Your sister can rake at a rate of 2
square meters per minute, and you can rake at a rate of 4 square meters per minute. You
start at the same time. After how many minutes will you rake 8 square meters more than
Your sister?

Answers

Answer 1

Answer:

4 minutes

Step-by-step explanation:

Min. Sister. You

1. 2. 4

2. 4. 8

3. 6. 12

4. 8. 16

Answer 2
4 minutes
If you started at the same time, and both your sister and you stay at the same constant rate, you would have raked 8 more squared meters than her after 4 minutes.
Zero minutes:You rated 0, she raked 0
One minute:You raked 4, she raked 2
Two minutes:You raked 8, she raked 4
Three minutes:You raked 12 she raked 6
Four minutes:You raked 16 she raked 8

A Sand dune stands 5 feet above sea level. the hill is eroding at a rate of 1 foot per 20 years. let y represent the height of the sand dune after x years. which equation represents the situation

Answers

Answer:

5 - (1 + 20) = yx

Step-by-step explanation:

So if 5ft is the original height, we would need to distribute that to decrease in the following years. That is where the 5 - comes from. Next we know that is it is eroding 1 foot in 20 years so that is 5- (1+20) You HAVE to distribute that and not add. Then it equals y the height of the dune in x, the years. Honestly 5 feet above sea level is kinda puny for a sand dune ;P.

Andrew participated in a bicycle race. The total distance covered was 56
miles. If he cycled at a constant rate of 14 miles per hour, how much time
did Andrew take to complete the race?
O A) 1 hr.
B) 4 hr.
C) 7 hr.
OD 9 hr.

Answers

(B) 4 hr is the correct answer.

Explanation :

★ Speed of body is defined as the ratio of distance travelled to the time taken[tex].[/tex]

speed = distance/time

Given that,

distance = 56 miles

speed = 14 miles per hour

By substituting the values, we get

⭆ time = distance/speed

⭆ time = 56/14

⭆ time = 4 hr

Solve 3kx + 24 = 9 kx for x.

Answers

Answer:

Step-by-step explanation:

3kx + 24 = 9kx

First subtract 3kx to both sides.

24 = 9kx  - 3kx

24 = 6kx

Divide both sides by 6

24/6 = kx

4 = kx

Divide both sides by k.

4/k = x

A pizza restaurant charges a flat fee for a plain cheese pizza. There is an extra charge for any additional toppings. The cost of a pizza can be determined from the equation c=0.5m+5, where M is the number of additional toppings and see is the cost of the pizza ordered. What are the interpretations of slope and Y intercept in the equation?

Answers

Answer:

The y-intercept is the flat fee for the pizza - $5. The slope is the charge for each additional topping - $.50

Step-by-step explanation:

c=.5m+5

y=mx+b - slope intercept formula

In the slope-intercept formula, the 'b' is the y-intercept. We know that would be the flat fee because there is no variable attached to it.

In that formala, m is the slope and is attached to a variable, x. This problem uses the variable m instead of x, but we can see that the slope for .5m would be .5. Thus, that's the charge for the toppings. Hope that helps!

A figure with 4 sets of parallel sides is graphed on a grid. The figure is then rotated 90 degrees clockwise. How many pairs of parallel sides does the figure have after the rotation?

Answers

Answer:

Step-by-step explanation:

After being rotated by 90 degrees, the figure has 4 pairs of parallel sides.

What is 90° rotation of an object?

The transformation P(x, y) P' can be used to represent a 90° rotation for any point in the plane (x, y) (-y, x). This transition can be produced by applying two reflections.Transformation involves moving a shape from one position to another  

Given data ,

A figure with 4 sets of parallel sides is graphed on a grid

The figures with 4 sets parallel sides are : Rhombus, Square , Rectangle

The figure is then rotated 90° clockwise

Now ,

90 degrees clockwise transformation carries the square , rhombus as well as the rectangle onto itself that is after rotation there will be 4 pairs of parallel sides

Hence , after being rotated by 90 degrees, the figure has 4 pairs of parallel sides.
