Step-by-step explanation:
Acceleration= (final velocity - initial velocity)/ time
= v-u/t
v = 20m/s
u = 5m/s
t= 30s
= 20-5/30
= 15/30

The solution is, her speed was, A) 0.1 mile per minute.
What is speed?Speed is measured as distance moved over time. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
Speed = Distance/ Time.
here, we have,
Explanation:
From physics we know that distance, time and speed are related by the following equation:
Speed = Distance/ Time.
So we can write the distance as:
d = s*t
Here we have a line that passes through the origin and whose independent variable is t and dependent variable is d and the slope is s. From the graph, we can calculate the equation of the line as:
y = mx;
where, slope = m = y2 - y1 / x2 - x1
here, (x1, y1 ) = (0,0)
(x2, y2 ) = (10, 1 )
we get, m = 1/ 10
So:
y = x/10
or, y = 0.1 x
As you can see from the graph:
y is related to distance (d)
x is related to time (t)
Therefore, we can rewrite our equation as:
d = 0.1 t
Finally, the speed (s) is:
s = 0.1 per mile
again, we have,
The line goes through (0, 0), so Maria's speed is the ratio of miles to minutes:
(4.5 mi)/(45 min) = 0.1 mi/min
hence, The solution is, her speed was, A) 0.1 mile per minute.

How do you find the area and perimeter of a rectangle. And how do you find the area and perimeter of a square?
Answer:
The perimeter of a rectangle is P = 2 b + 2 h , where is the base (or width) and is the height (or length). If a rectangle is a square, with sides of length , the formula for perimeter is P s q u a r e = 2 s + 2 s = 4 s and the formula for area is A s q u a r e = s ⋅ s = s 2

Describe how you can tell whether a line’s slope is greater than 1, equal to 1, or less than 1.
Answer:
the slope is determined by rise over run, meaning you first have to see if the line is negative or positive by the direction it is facing,then you have two points that match accordingly to rise over run,to find out you have to see how many boxes(y) you are rising and however many boxes to the right(x) you are running,then you divide rise/run(look in picture attached for more)

The side of a square is Two raised to the seven halves power inches. Using the area formula A = s2, determine the area of the square.
Answer:
Step-by-step explanation:
Area of a square = s²
s is the side length of the square
Given
s = 2^{7 1/2}
s = 2^15/2
Area = ( 2^15/2)²
Area = 2^15
Hence two area of the square is 2^15 inches
Answer:
A = 128 square inches
Step-by-step explanation:
A square is a figure with equal length of sides.
Given a square of side, s, [tex]2^{\frac{7}{2} }[/tex] inches.
Area of a square, A = length of side x length of side
= s x s
= [tex]s^{2}[/tex]
Thus,
A = [tex]s^{2}[/tex]
= [tex](2^{\frac{7}{2} } )^{2}[/tex]
= [tex]2^{\frac{14}{2} }[/tex]
= [tex]2^{7}[/tex]
= 128
A = 128 square inches
The are of the square is 128 square inches.

The equation is x + 28 = 224. Then the amount earned by babysitting will be $196.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Nandita earned $224 last month. She earned $28 by selling cards at a craft fair and the rest of the money by babysitting.
Let 'x' be the amount earned by babysitting. Then the equation is given as,
x + $28 = $224
Simplify the equation for 'x', then we have
x + $28 = $224
x = $224 - $28
x = $196
The equation is x + 28 = 224. Then the amount earned by babysitting will be $196.

Tobin and me, the two of us, went down to Coney one day. There was four dollars between us. Tobin had need of distractions. Katie Mahorner, his sweetheart, of County Sligo, was lost since she started for America three months before. She had two hundred dollars of her own savings, and one hundred dollars from the sale of Tobin's inherited estate, a fine cottage and pig on the Bog Shannaugh. Since Tobin got the letter saying that she had started to come to him, not a bit of news had he heard or seen of Katie Mahorner. Tobin advertised in the papers, but nothing could be found of the girl.

Write an equation in slope-intercept form for the line with slope -3 and y-intercept -1. Then graph the line.
Answer:
y=-3x+-1 or y=-3x-1; y intercepts(0,-1); x intercepts(0,1/3)
Step-by-step explanation:
y=mx+b
-1=-3*0+b
-1=0+b
(subtract 0 from both sides)
-1=b
So your equation will be: y=-3x-1
The equation of the line with a slope of -3 and y-intercept of -1 is given as y = -3x - 1. And the graph is shown below.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
Write an equation in slope-intercept form for the line with slope -3 and y-intercept -1.
We know that the equation of the line is given as
[tex]\rm y = mx +c[/tex]
Where m is the slope and c is the y-intercept. Then the equation will be
[tex]\rm y = -3x - 1[/tex]
Then the graph of the line is given below.
