Patrick is in a grocery store parking lot, 90meters away from his car. If he pushes his shopping cart at a constant velocity of 2meterspersecond toward his car, how much time will it take him to get one-third of the way to his car?
Write your answer as a whole number.
15 seconds of time will it take him to get one-third of the way to his car
What is Distance?The length along a line or line segment between two points on the line or line segment.
Given,
Patrick is in a grocery store parking lot, 90meters away from his car
Patrick pushes his shopping cart at a constant velocity of 2meterspersecond toward his car.
We need to find time will it take him to get one-third of the way to his car
one-third of the way to his car means 1/3 of 90 which is 30 meters.
Speed =Distance/ Time
Time=Distance/speed
=30/2
=15 units.
Hence, 15 seconds of time will it take him to get one-third of the way to his car

15 points!! Is the triangle a right triangle?
Answer: Yes.
Step-by-step explanation:
Answer:
yes, it is because the right side is the bigger side.
Step-by-step explanation:
See in a right triangle, the side that is opposite of the 90° angle is the longest side of the triangle, and is called the hypotenuse.
In ARST, r = 71 cm, /T=48° and /R=37°. Find the length of t, to the nearest 10th of
a centimeter.
In the given triangle, the length of side t is 87.7 cm
Calculating the length of a side in a triangleFrom the question, we are to determine the length of t.
From the given information,
r = 71 cm
∠T = 48°
∠R = 37°
From the law of sines, we can write that
t / sin T = r / sin R
t / sin 48° = 71/sin 37°
t = (71 × sin 48°)/sin 37°
t = 87.6736
t ≈ 87.7 cm
Hence, the length of t is 87.7 cm

ethanol. The fuel contains either 13 percent ethanol or 69 percent
ethanol. How much of 69% percent ethanol fuel should you use so
that your tank is 40 percent ethanol?
Answer: 7.5
Step-by-step explanation:
the tank is 15 gallons and you can get 13 percent ethanol or 69 percent ethanol, so you simply just get 7.5gallons of 69 percent and then 7.5 gallons of 13 percent
.69 divided by 15 is .046
.13 divided by 15 is .008
The amount of 69% percent ethanol fuel should you use so that your tank is 40 percent ethanol is equivalent to 4.35 gallons.

The length of a rectangle is 3ft longer than its width.
If the perimeter of the rectangle is,58ft find its length and width.
The length and width of the rectangle is 16 ft and 13 ft respectively.
What is the dimensions of the rectangle?The perimeter of a rectangle = 2(length + width)
Perimeter of the rectangle = 58 ftWidth of the rectangle = w ftLength of the rectangle = (w + 3) ftThe perimeter of a rectangle = 2(length + width)
58 = 2{(w + 3) + w}
58 = 2(w + 3 + w)
58 = 2(3 + 2w)
open parenthesis
58 = 6 + 4w
subtract 6 from both sides
58 - 6 = 4w
52 = 4w
divide both sides by 4
w = 52/4
w = 13
Hence,
Width of the rectangle = w ft
= 13 ft
Length of the rectangle = (w + 3) ft
= 13 + 3
= 16 ft
Therefore, the dimensions of the rectangle is given by 16 ft and 13 ft respectively

The price for 7/8 of a pound of almonds is $6.65 . What is the cost of 3 and 1/2 pounds at the same rate?
The cost of 3 and 1/2 pounds of almond at the same rate is $26.60.
What is a fraction?A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In the illustration given as m/n, it should be noted that m is the numerator and n is the denominator.
Since the price for 7/8 of a pound of almonds is $6.65, the fraction per pound will be done by dividing the amount for a pound by 7/8.
= $6.65 ÷ 7/8
= $7.6
The cost of 3 and 1/2 pounds at the same rate is:
= 3 1/2 × $7.6
= $26.60

Find the equation for the line that passes through the point (−2,0), and that is parallel to the line with the equation y=−12x−72
The linear equation parallel to y = -12x - 72 that passes through (-2, 0) is:
y = -12x - 24
How to find the linear equation?A general linear equation is written as:
y = m*x + b
Where m is the slope, and b is the y-intercept.
And two lines are parallel only if the lines have the same slope and a different y-intercept.
So, if we want to find a line parallel to:
y = -12x - 72
Then the slope of our line must be -12, then our line is something like:
y = -12x + b
Now we know that the line must pass through (-2, 0), replacing that in our line we get:
0 = -12*-2 + b
0 = 24 + b
-24 = b

7. Casey bought a 15.4-pound turkey and an 11.6-pound ham for Thanksgiving and paid $38.51. Her
friend Jane bought a 10.2-pound turkey and a 7.3-pound ham from the same store and paid $24.84.
Find the cost per pound of turkey and the cost per pound of ham.
Answer:
t = 1.195pounds.
Step-by-step explanation:
The cost per pound of Turkey and Ham are: 1.195pounds and 1.733pounds respectively.
By observing the question, we must notice this is a word problem and can be written mathematically thus;
For Casey:
15.4t + 11.6h = 38.51
For Jane:
10.2t + 7.3h = 24.84
Therefore, to find the cost per pound of Turkey and Ham, the pair of equations need to be solved simultaneously.
Therefore, we can make t the subject of the formula in equation (2) as follows;
t = (24.84 - 7.3h)/10.2
Therefore, we can substitute the value of t into equation (1) to get;
15.4{(24.84 - 7.3h)/10.2} + 11.6h = 38.51
37.51 - 11.023h + 11.6h = 38.51
0.577h = 1
h = 1.733pounds
Therefore, by substituting the value of h into equation 1, we get the value of t to be;
t = 1.195pounds.

A canoe rental service charges a $20 transportation fee and $30 dollars an hour to
rent a canoe. Write and graph an equation representing the cost, y, of renting a canoe
for x hours. What is the cost of renting a canoe for twelve hours?
The graph of the equation y = 30x + 20 is shown below.
It would cost $380 for 12 hours.
How to Write and Graph an Equation?The equation of a graph can be written as y = mx + b, if we know the slope of the graph (m) and the y-intercept (b) which is the point on the y-axis that the line will intercept.
Therefore:
Slope/unit rate (m) = $30 per hour
Rental service charges is the y-intercept (b) = $20
To write the equation, substitute m = 30 and b = 20 into y = mx + b:
y = 30x + 20
See the attachment below for the graph of the equation.
Substitute x = 12 into the equation y = 30x + 20 to find the cost of renting canoe for 12 hours:

One rectangle is "framed" within another. Find the area of the shaded region if the "frame" is 2 units wide. 7 and 2
24 units is the area of the shaded region if the "frame" is 2 units wide.
What is Area of Rectangle?The area of Rectangle is length times of width
We know that the frame is 2 units wide, and the measure of the rectangle and the frame are:
width = 7 units
length = 12 units
Now, if we remove the frame, we will remove 2×2 units = 4 units for each measure (because for each measure we have the frame in both sides).
So the measures for the shaded rectangle are:
width = 7 units - 4 units = 3 units
length = 12 units - 4 units = 8 units.
And the area of a rectangle is given by the product between the width and length, then we have:
A = (3 units)*(8 units) = 24 square units.
Hence, 24 units is the area of the shaded region if the "frame" is 2 units wide.
