The perimeter of a rectangle is 42 inches if the width of the rectangle is 6 inches what is the length
Answer:
The length would be 15 inches.
Step-by-step explanation:
Since we are solving for perimeter the first step would be doing 6+6 = 12 (covering 2 sides). The next thing we would do is subtract 12 from 42 getting 30 as our answer. We need to divide 30 by 2 to get an answer of 15. I hope this helps! :)

Penelope’s 2000 kg new painted car accelerates from 50.0 m/s to 100.0 m/s. Calculate the impulse experienced by Penelope’s car.(Note: Include correct units and sign. Ex. "20 J" , "20 m" , "20 m/s")
The impulse that Penelope's car would experience is 100, 000 Kg. m/s
How to calculate the impulse
The formula for calculating the impulse is;
Impulse = m Δ v
Where m = mass = 2000kg
Δv = change in velocity = 100 - 50 = 50m/s
Substitute values into formula
Impulse = 2000 × 50 = 100, 000 Kg. m/s
Therefore, the impulse would be 100, 000 Kg. m/s

What are m∠1 and m∠2?
Answer:
B. <1 = 35, m<2 = 30
Step-by-step explanation:
To figure out m<1 I first need to figure out the other missing angle. A straight line is a 180 degree angle. Taking that information you can do 180 - 115. This means that the missing angle is 65 degrees. The interior angles of triangles always add up to 180.
80 + 65 = 145
180 - 145 = 35
<1 = 35
Repeat with the other side.
85 + 65 = 150
180 - 150 = 30
<2 = 30

What is the y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1? m Y 1 77](V₂ − V₁] + V₁ m+n -8 -5 0 6
The y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.
How to carry out division of line segments?
From the attached line segment graph, we see the coordinates as;
J (1, -10) and K (7, 2)
Let us assume that, point L divides the directed line segment from J to K into a ratio of 5:1.
From the properties of coordinate geometry we know that, the coordinates of point that divides the line joining (x₁, y₁), (x₂, y₂) in m:n, are;
[(mx₂ + nx₁)/(m + n)], [(my₂ + ny₁)/(m + n)]
Plugging in the relevant values gives;
[(5 * 7 + 1 * 1)/(5 + 1)], [(5 * 2 + 1 * -10)/(5 + 1)]
⇒ (6, 0)
Therefore, the y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.

Seven x's and 3y's cost as much as 4z's. One z costs as much as 1x plus 1y together. How many x's cost as much as 1y?
Answer:
Step-by-step explanation:
Equations
7x + 3y = 4z
Second equation
x + y = z Multiply the entire equation by 4
4[x + y = z] Now distribute the 4 through the equation
4x + 4y = 4z Both equations = 4z. Equate the lefts.
Third equation
7x+3y = 4x + 4y Subtract 3y from both sides
7x + 3y -3y = 4x + 4y -3y
7x = y + 4x Subtract 4x from both sides
7x - 4x = y + 4x - 4x Combine
3x = y
Answer: 3x = y
Big Brothers, Inc. borrows $267,999 from the bank at 18.16 percent per year, compounded annually, to purchase new machinery. This loan is to be repaid in equal annual installments at the end of each year over the next 10 years. How much will each annual payment be?
Round the answer to two decimal places.
Based on the amount borrowed and the interest per year, Big Brothers, Inc will pay an annual payment of $59,973.15.
How much will Big Brothers, Inc. pay annually?This can be found by using the present value of an annuity formula because the annual payment will be constant and therefore like an annuity.
Formula is:
Present value of annuity = Annual payment x ( 1 - (1 + rate) ^ -number of periods) / rate
Solving gives:
267,999 = Amount x ( 1 - ( 1 + 18.16%)⁻¹⁰) / 18.16%
267,999 = Amount x 4.46865
Amount = 267,999 / 4.46865
= $59,973.15
