A car is moving at a constant acceleration of 7.0 m/s/s. How fast (velocity) is it going after 4.0 seconds, if it starts from rest.? Show work using ESA format.
Answers
28 m/s is the velocity , when it is going after 4.0 seconds.
What is Acceleration?When a point or an object moving in a straight line , the acceleration is the rate at which velocity changes with time, in terms of both speed and direction.
Here, given that,
A car is moving at a constant acceleration of 7.0 m/s/s
Now, we have,
Velocity = acceleration * time
After 4 sec. = 7*4 = 28 m/s
Hence, 28 m/s is the velocity , when it is going after 4.0 seconds.

We are given that y = 4x and the equation is 3x - y = 1.
We need to evaluate.
3x - y = 1
||
\/
3x - 4x = 1.
To make the equation true, x = -1.
||
\/
3(-1) - 4(-1) =
-3 minus -4 = 1.
Final answer:
Explains how to solve a system of two linear equations by substitution.
Explanation:
The provided equations are:
y = 4x
3x - y = 1
To solve the system of equations, we can substitute the value of y from the first equation into the second equation:
Substitute y = 4x into 3x - y = 13x - 4x = 1-x = 1x = -1Substitute x = -1 back into y = 4x to find yTherefore, the solution is x = -1 and y = -4.
Sean wrote the equation 9.25 = 5m, where m is the cost per pound of pears, to show the relationship between the total cost and the number of pears he bought at Quick Mart.
What is the unit cost per pears? Write an equation.
Does this relationship represent a proportional relationship? Use a graph to prove it. Explain how the graph proves the situation is a proportional relationship.
Answers
Answer:
see the explanation
Step-by-step explanation:
The correct question is
Sean wrote the equation 9.25=5m, where m is the cost per pound, to show the relationships between the total cost, $9.25, and the number of pounds of pears, write an equation to show the cost y of x pounds of pears, and use the equation to complete the table. then use the information in your table to make a graph
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
y ----> the total cost
x ---> the number of pounds of pears
In this problem we have a proportional relationship between the variables x and y
we have
[tex]9.25=5m[/tex]
where
m is the cost per pound of pears
That means
The value of m and the value of the constant k of proportionality is the same
Find the value of m
[tex]9.25=5m\\m=\$1.85\ per\ pound[/tex]
The linear equation is equal to
[tex]y=1.85x[/tex]
Construct the table
assume different values of x and determine the value of y
[tex]For\ x=0 ----> y=1.85(0)=0[/tex]
[tex]For\ x=1 ----> y=1.85(1)=1.85[/tex]
[tex]For\ x=2 ----> y=1.85(2)=3.70[/tex]
[tex]For\ x=3 ----> y=1.85(3)=5.55[/tex]
[tex]For\ x=4 ----> y=1.85(4)=7.4[/tex]
[tex]For\ x=5 ----> y=1.85(5)=9.25[/tex]
therefore
[tex]\begin{array}{cc}x(\text{Number of pounds}) & y(\text{Cost in dollars})\\0 & 0\\1 & 1.85\\2 & 3.7\\3 & 5.55\\4 & 7.4\\5 & 9.25\end{array}[/tex]
using a graphing tool
The grahp in the attached figure
Final answer:
The unit cost per pound of pears is $1.85, found by dividing the total cost ($9.25) by the number of pounds (5). This represents a proportional relationship, as the graph of the equation y = 5x is a straight line through the origin, showing a constant ratio of total cost to pounds of pears.
Explanation:
The question regarding the equation 9.25 = 5m asks us to find the unit cost per pound of pears and determine whether the relationship represents a proportional relationship. To find the cost per pound, we simply need to divide both sides of the equation by 5. This gives us m = 9.25 / 5, which calculates to m = $1.85. Therefore, the unit cost per pound of pears is $1.85.
To test for a proportional relationship, we can graph the equation y = 5x, where 'y' is the total cost and 'x' is the number of pounds of pears. A proportional relationship is one where the ratio of y to x is constant, and the graph is a straight line through the origin. Since our equation represents a linear relationship that passes through the origin (0,0), it confirms that this is, indeed, a proportional relationship. The graph would show a straight line with a slope of 5, indicating that for every increase of 1 pound of pears, the cost increases by $5.

how much wrapping paper would you need to cover a rectangular that is 18.25 inches by 12inches by 3 inches if you need 10% more wrapping paper than the surface area of the box? give your answer to the nearest square inch
Answers
Answer: 681 square inch
Step-by-step explanation:
Hi, we have to apply the formula for the surface area:
A = 2wl + 2lh + 2hw
Where:
w: width
l: length
h: height
Replacing with the values given:
A = (2x12x18.25) + (2x12x3)+(2x18.25x3)
A= 438+72+109.25
A=619.5 in2
Since it has to be 10% more than the surface.
619.5 x (10/100) = 61.95 in2
Adding that value to the surface area
619.5+61.95 = 681.45in2 = 681 in2

tom and adam have a total of 240 stamps.The ratio of the number of tom's stamps to adam's is 3:7.Tom buys some stamps from Adam.The ratio of tom's stamp to adam's is now 3:5.How many stamps does tom buy from adam
Answers
Answer:
18
Step-by-step explanation:
In both cases, the number remains constant, 240 stamps.
Given that 3:7 is equal to 3/10 to 7/10
Initially, Tom had 3/10*240=72 stamps
Finally, 3:5 equal to 3/8 to 5/8
Tom has 3/8*240=90 stamps
Difference is 90-72=18 stamps
Therefore, Tom bought 18 stamps from Adam and Adam didn't replace
Given the initial and new ratios of Tom's and Adam's stamps, and the total number of stamps they have, we can setup and solve an equation which reveals that Tom bought 48 stamps from Adam.
Explanation:This math question involves the concept of ratios and some algebra. Given that Tom and Adam initially had a total of 240 stamps between them in a ratio of 3:7, we can divide 240 by the total parts of their ratio (3 + 7 = 10 parts). So, one 'part' is 240 divided by 10, which equals 24.
Therefore, Tom initially had 3 parts i.e., 3*24 = 72 stamps while Adam had 7 parts i.e., 7*24 = 168 stamps.
After Tom buys some stamps from Adam, their ratio changes to 3:5. Let's denote the number of stamps Tom bought as x. Then, Tom would have 72 + x stamps, while Adam would have 168 - x stamps.
Since their ratio is now 3:5, we can set up an equation represented by (72 + x) / (168 - x) = 3 / 5. Solving this equation gives us x = 48.
So, Tom bought 48 stamps from Adam.

Answer:
180 - 116 = 64 so the congruent angles measure 64/2 which is 32.
Step-by-step explanation:
Final answer:
To find the measure of the congruent angles in a triangle with one angle measuring 116°, you can use the fact that the sum of the interior angles of a triangle is 180 degrees. By solving the equation, you can calculate the measure of the congruent angles as 32°.
Explanation:
Question: One angle of a triangle measures 116°. The other two angles are congruent. Enter and solve an equation to find the measure x of the congruent angles.
To find the measure of the congruent angles, we know that the sum of the angles in a triangle equals 180 degrees. Let x be the measure of each congruent angle, then the equation to solve is: 116 + x + x = 180. Simplify to find x.
Answer: By solving the equation 116 + x + x = 180, x = 32°. Therefore, each congruent angle measures 32°.

A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 1,017.36 square feet use 3.14 for pi
Answers
Answer:
18
Step-by-step explanation:
1,017.36 is the area of the circle and you need to find the radius
area formula : 3.14rsquared
so the formula you are going to solve for your answer is 3.14rsquared=1,017.36
divide by 3.14
rsquared = 324
un square it to get you radius which is 18
you didnt clarify whether you wanted radisu or diameter so ill give both
R: 18
D:36
Answer:
The sprinkler can spread water up to 36 feet away!
Step-by-step explanation:
First, identify the formula used to find the area of a circle:
Area = pi x r^2
We already know the area that the sprinkler makes, so just plug that in! Then, we just need to reverse engineer the formula!
1,017.36 square feet = pi x r^2
1,017.36 square feet= 3.14 x r^2
1,017.36/3.14 = r^2
324 = r^2
sqrt of 324 = 18
So, we figured out that the radius of the circle is 18 feet! Now, remember the radius is just half the amount of the diameter!
18 x 2 = 36 feet
