1. Roderick can water his lawn with a small hose or
a large hose. The small hose pumps 15 gallons of
water per minute. The large hose pumps water at
twice the rate of the small hose. Graph the
relationship between time and the gallons of water
pumped by the large hose.

Answers

Answer 1

The graph showing the relationship between time and the gallons of water pumped by the large hose is given below.

What is Slope?

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Given that,

Roderick can water his lawn with a small hose or a large hose.

The small hose pumps 15 gallons of water per minute.

So the slope of the graph is 15.

If the amount of water pumped by small hose is represented by y, and the time taken is represented by x,

y = 15x

The large hose pumps water at twice the rate of the small hose, that is 30 gallons per minute.

So the slope is 30.

If the amount of water pumped by large hose is represented by y', and the time taken is represented by x',

y' = 30x

So the points in the graph are, (0, 0), (1, 30), (2, 60),.....

Hence the graph is drawn below.

Lines j and k are parallel. They are intersected by the transversals, l and m.

Answers

Answer:72

Step-by-step explanation:

72 and the angle to the top right of x are corresponding angles. This means they are the same. Using this, we can see that the same angle to the top right of x that we now know is 72 is also vertical to x. Vertical angles are also equal, so x = 72

The value of x is 72°

Parallel lines:

Parallel lines are lines in the same plane and of the the same distance.

The parallel line j and k are intersected by the transversals l and m.

Therefore, corresponding angles, alternate angles etc. can be formed.

Since the pair of parallel lines are cut by the transversal lines then the alternate exterior angles are congruent . Therefore,

x = ∠72°

∠x ≅ ∠72°(alternate exterior angles)

Step-by-step explanation:

On a position-time graph, "does not move" means the position is a constant—a horizontal line.

"Positive velocity" means the position is increasing as time increases. The graph goes up to the right. The rate of change (slope) is the velocity.

"Negative velocity" means the position is decreasing as time increases. The graph goes down to the right. Again, the rate of change (slope) is the velocity.

The various sections of the graph are identified in the attachment.

Last week at the park, Heather ran 4 miles in 48 minutes. When she runs her next race, she hopes to improve her time by 2 minutes per mile.
Last week at the park, what was Heather’s rate of speed in miles per hour? Use words and/or numbers to explain your answer.​

Answers

Answer:

she ran 10 miles a hour

Step-by-step explanation:

she runs 10 miles a hour because she wants to improve her time per mile by 2 minutes so you do 2x4 and get 8, then you subtract 8 from 48 and get 40 then you divide 40 by 4 and get 10

Heather's rate of speed last week was 1/12 miles/min.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that last week at the park, Heather ran 4 miles in 48 minutes. When she runs her next race, she hopes to improve her time by 2 minutes per mile.

Heather's rate of speed last week -

{r} = 4/48 = 1/12 miles/min

{r} = 1/12 miles/min

Therefore, Heather's rate of speed last week was 1/12 miles/min.

What is a right-angle triangle?

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

Using sin ratio to find the value of x:

sin45 = X/1

1/√2 = X/1

X = (1/√2)(√2/√2)

X = √2/2

Thus, the length of the side is 1/√2 or √2/2 units after applying the sin ratio.

simplifying the expression

[tex]-6-7\left(c+10\right)[/tex]

Expanding -7(c + 10) = -7c - 70
