A wire is first bent into the shape of a triangle. Each side of the triangle is long. Then the wire is unbent and reshaped into a square. What is the length of a side of the square?
Answers
Answer:
18 inStep-by-step explanation:
Here is the complete question.
A wire is first bent into the shape of a triangle. Each side of the triangle is 24in long. Then the wire is unbent and reshaped into a square. What is the length of a side of the square?
A triangle have 3 sides. If each sides is 24in long, the perimeter of the triangle will be:
P = s1 + s2 + s3
P = 24in + 24in + 24in
P = 72in
If the same length of wire is unbent and reshape into a square, this means:
Perimeter of the triangle = Perimeter of the square
Perimeter of the square = 72in
To get the length of a side of a square, we will use the formula:
Perimeter of a square = 4L
72 = 4L
L = 72/4
L = 18in
Hence the length of a side of the square will be 18in.

Whitney sells cars at a local dealership. She receives a monthly salary of $904.00 and a $159.00 commission on each car she sells. If Whitney receives her commission check at the end of the month along with her salary check, which of the following equations can be used to determine her total pay for the month?
(Let x represent the number of policies sold and y represent the total amount of pay for the month.)
A.
y = 904x + 159
B.
y = 159x
C.
y = 159x + 904
D.
y = 15.9x + 904
Answers
Answer:
The equation can be used to determine her total pay for the month is
y = 159x + 904 ⇒ C
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope ⇒ rate of changeb is the y-intercept ⇒ initial amount∵ Whitney receives a monthly salary of $904.00
→ It is a fixed amount
∴ The initial amount of her salary is $904.00
∴ b = 904
∵ She takes a $159.00 commission on each car she sells
→ That means the commission is changing with the number of cars sold
∴ The commission is the rat of change
∴ m = 159
→ Substitute the values of m, b in the form of the equation above
∴ y = 159x + 904
The equations can be used to determine her total pay for the month is
y = 159x + 904

Answers
Answer:
$468.12
Step-by-step explanation:
Given that:
Amount to deposit:
Check 1: = $95.62
Check 2 = $432.50
Amount he'll like to receive or withdraw = $60
Total amount he'll be depositing :
Check 1 + Check 2 - withdrawal
$95.62 + $432.50 - $60
= $468.12

Write an equation in slope-intercept form for the line with slope 1/5 and y-intercept -8
Answers
Answer:
y= 1/5x + -8
Step-by-step explanation: slope-intercept form= y=mx+b
y= the number on the y-axis or the simple y
m=slope
x= the number on the x-axis or the simple x
b= y-intercept
The required slope-intercept form of the equation is given as y = 1/5x - 8.
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The slope intercept of the equation is given as,
y = mx + c,
From the given, we have a slope of line m = 1/5 and y-intercept, c = -8.
Now,
y = mx + c
y = 1/5x - 8
Thus, the required slope-intercept form of the equation is given as y = 1/5x - 8.

A farmer wants to increase the weight of her lambs and is considering supplementing their diets with niacin, which is advertised as an effective weight gain supplement. To add niacin to their diets, the farmer would need to purchase a supply, which is fairly expensive. But if it does actually increase the weights of her lambs, it will lead to higher sales for her farm over time. So she conducts an experiment where she compares the weight gains of a sample of lambs on regular feed to a sample that receives an additional niacin supplement. a. Write an appropriate null and alternative hypothesis for her experiment. (1pt) b. In the famer’s perspective, explain the consequence of a Type-I error. (1pt) c. In the famer’s perspective, explain the consequence of a Type-II error. (1pt) d. Suppose the farmer analyzed her experimental data and got a p-value of 0.15. What would be the appropriate conclusion? (2pt) e. List a potential confounding variable for this study
Answers
Answer:
H0: ρ= 0 against Ha : ρ≠0
Step-by-step explanation:
The null hypothesis would be the weight gains of a sample of lambs on regular feed is equal to the weight gains of the sample that receives an additional niacin supplement against the claim that the weight gains are not equal .
H0: ρ= 0 against Ha : ρ≠0
Type 1 Error would be when the H0 is true and there's no difference but H0is rejected or Ha is accepted that there is difference in the weight gains.
Type 2 Error would be when the Ha is true and there is difference but Ha is rejected or H0 is accepted that there's no difference in the weight gains.
The appropriate conclusion would be Ha is accepted and H0 is rejected fail to reject.
A confounding variable is the one which effects the results . It is the biased variable which should be identified and ignored.
For example in this experiment the independent variable would be the amount of the supplement the dependent would the weight gain but the gender of the sheep is the confounding variable. It is not directly related to amount of supplement .
1) gender of sheep
2) the breed of sheep
3) the number of sheep
4) the height of sheep

Tomas is making trail mix using granola and walnuts. He can spend a total of $12 on the ingredients. He buys 3 pounds of granola that costs $2.00 per pound. The walnuts cost $6 per pound. He uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. He solves the equation for y, the number of pounds of walnuts he can buy. Which is the first error that Tomas made? Tomas substituted the 3 for x when he should have substituted 6 for x. Tomas added 6 to both sides of the equation instead of subtracting 6. Tomas should have written the equation as . Tomas substituted 3 for x when he should have substituted 3 for y.
Answers
Correct question is;
Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. The walnuts cost $6 per pound. He uses the equation 2x + 6y = 12 to represent the total cost,
Where x represents the number of pounds of granola and y represents the number of pounds of walnuts. He solves the equation for y, the number of pounds of walnuts he can buy.
2x + 6y = 12
2(3) + 6y = 12
6 + 6y + 6 = 12 + 6
6y = 18
y = 3
which is the first error that tomas made?
A) tomas substituted the 3 for x when he should have substituted 6 for x.
B) tomas added 6 to both sides of the equation instead of subtracting 6.
C) tomas should have written the equation as 3x + 6y = 12.
D) tomas substituted 3 for x when he should have substituted 3 for y.
Answer:
Option B: tomas added 6 to both sides of the equation instead of subtracting 6.
Step-by-step explanation:
We are told that; x represents the number of pounds of granola while y represents the number of pounds of walnuts.
Now, we are told that He can spend a total of $12 on the ingredients. Also that he buys 3 pounds of granola that costs $2.00 per pound while the walnuts cost $6 per pound.
Thus;
2x + 6y = 12
He buys 3 pounds of granola. Thus;
2(3) + 6y = 12
6 + 6y = 12
The next step here is to subtract 6 from both sides but Tomas added 6 to both sides instead.
Thus, option B is the correct answer.

The distance an electric car can travel on one full charge depends on the speed of the car. The table shows the approximate distances a certain model of electric car can travel on one full charge
when moving at various constant speeds.
The speed and the corresponding distance form an arithmetic sequence, where the speed represents the number of the term and the corresponding distance represents the value of the term.
What is the distance, in miles, that the car can travel on one full charge when moving at a constant speed of 75 miles per hour (mph)?
A) 220
B250
С270
D290
Answers
Answer:
Distance covered by the car = 220 miles
Step-by-step explanation:
Speed (mph) (s) Distance (miles) (d) Difference in distances
45 400 -
50 370 400 - 370 = 30
55 340 370 - 340 = 30
60 310 340 - 310 = 30
65 280 310 - 280 = 30
Since differences between each successive term of the distances are common,
Therefore, table represents a linear function.
Let the equation representing the relation between the speed and distance is,
d = ms + c
Where m = slope of the line
And c = y-intercept
For a point (45, 400) lying on the line,
400 = 45m + c ----- (1)
Similarly, for a point (60, 310),
310 = 60m + c -------(2)
Equation (1) - equation (2)
400 - 310 = 45m - 60m
90 = -15m
m = -6
By substituting m = -6 in equation (1),
400 = 45(-6) + c
c = 400 + 270
c = 670
Therefore, equation will be,
s = -6d + 670
Now we have to calculate the distance covered by the car when moving with a constant speed of 75 mph,
d = -6(75) + 670
d = 670 - 450
d = 220 miles
