Answer:
The dimensions of Marianne scarf = 12 × 7 inches
The length of the scarf =12inches
The width of the scarf = 7 inches
Step-by-step explanation:
Step(i):-
Let 'x' be the width of the scarf
Given that the length of the scarf = x+5
The area of the rectangle = length × width
Given that the area of the rectangle (scarf) = 84 square inches
Step(ii):-
length × width = 84
(x+5) × x = 84
x² + 5x - 84 =0
x² + 12 x - 7 x - 84 =0
x(x+12) -7( x+12) =0
(x-7)(x+12) =0
x -7 =0 and x+12=0
x =7 and x= -12
Step(iii):-
We have to choose x =7
The length of the scarf = x+5 = 7+5 =12inches
The width of the scarf = x = 7 inches

Jane has just begun her new job as on the sales force of a very competitive company. In a sample of 16 sales calls it was found that she closed the contract for an average value of 108 dollars with a standard deviation of 12 dollars. Company policy requires that new members of the sales force must exceed an average of more than $100 per contract during the trial employment period. Can we conclude that Jane has met this requirement at the significance level of 90%
Answer:
There is significant evidence that Jane has met the requirement.
Step-by-step explanation:
Given that:
μ = 100
μ > 100
Sample size, n = 16
Sample mean, x = 108
Sample standard deviation, s = 12
Level of significance, α = 0.1
Degree of freedom, df = n - 1 = 16 - 1 = 15
Test statistic
T = (x - μ) / s÷sqrt(n)
Tstatistic = (108 - 100) / 12 ÷ sqrt(16)
Tstatistic = 8 / 3
Tstatistic = 2.6667
Using the pvalue calculator :
Tstatistic at 0.1, df = 15 ;
P-value = 0.008799
Since pvalue < α
We reject the Null
The is no significant evidence to conclude that Jane has exceeded an average of more than $100

In the figure shown, determine the measures of the marked angles
Step-by-step explanation:
9x+4+2x=180
= 11x=176
= x=176/11
=x=16
2x=32°
9x+4=148°
The measure of two angles are 2x=31.6° and (9x+4)°=146.4°.
From the given figure, there are two angles 2x° and (9x+4)°.
What are adjacent angles?Adjacent angles are those angles that are always placed next to each other in such a way that they share a common vertex and a common side but they do not overlap each other.
Here,
2x°+(9x+4)°=180° (Sum of two adjacent angles is 180°)
⇒ 11x+4=180
⇒ 11x=174
⇒ x=174/11
⇒ x=15.8°
So, 2x=31.6° and (9x+4)°=146.4°
Therefore, the measure of two angles are 2x=31.6° and (9x+4)°=146.4°.

5(21+4) - i = 38
distributive property
Answer:
i = 87
Step-by-step explanation:
First, you would distribute 5 through the parenthesis by multiplying everything inside by 5. So 5*21=105 and 5*4=20. Next, you would add them together and simplify the equation to 125 - i = 38. Then you would subtract 38 from 125 to receive the equation 87 - i = 0. Finally, you would add i to both sides and get i = 87.

A jacket with an original price of $160 is on sale for 15% off what is the sale price
Answer:
$137.50
Step-by-step explanation:
Multiply 160 by 0.15 to find what 15% of 160. The answer is 22.5. Then subtract 22.5 from 160 to find the answer (137.50)
Answer:
$136
Step-by-step explanation:
To solve percent problems, you can use the formula part %
------- = -----
whole 100
The % would be 15, the whole would be 160, and the part would be x. Cross multiply to get 100x = 2400. Divide 2400 by 100 to get x = 24. Then, subtract 24 from $160 to get $136. The sale price is $136.
Ten full crates of walnuts weigh 370 pounds, whereas an empty crate weighs 10 pounds. How much do the walnuts alone weigh?
Answer:
so
Step-by-step explanation:
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The weight of the walnuts alone is 360 pounds
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example: 2x + 3 = 4 is an equation.
We have,
Number of craters of walnuts = 10
Weight of 10 craters of walnuts = 370 pounds
Weight of empty crate = 10 pounds
Weight of the 10 walnuts = M
Weight of the 10 walnuts + weight of the crater = 370 pounds
This can be written as an equation:
M + 10 = 370
Subtract 10 on both sides.
M = 370 - 10
M = 360 pounds
Thus,
The weight of the walnuts alone is 360 pounds

Philip is saving money to buy a new computer. He saves the same amount of money each week.
• After 2 weeks of saving, Philip still needs $520 to buy the
computer.
• After 6 weeks of saving, Philip still needs $300 to buy the
computer
How much does the computer cost?
(Note: Express the answer as dollars.cents.)
Answer:
If he still needs 520 to buy the computer in 2 weeks of saving, and 300 to buy the computer in 6 weeks of saving, he saves (520-300)/4, or 55 dollars each week.
So, at week zero, we can find the cost of the computer, which is 520+55+55, or 630 dollars.

A building casts a shadow that is 50 feet in length. If the distance from the end of the shadow to the top of the building is 250 feet, what is the height of the building
Answer:
The height of the building is of 244.95 feet.
Step-by-step explanation:
We use the Pythagorean Theorem to solve this question.
We have that:
The shadow of 50 feet is one side of the right triangle, while the height h is other side.
The hypotenuse is the distance from the end of the shadow to the top of the building, which is 250 feet.
So
[tex]50^2 + h^2 = 250^2[/tex]
[tex]h^2 = \sqrt{250^2 - 50^2}[/tex]
[tex]h = 244.95[/tex]
The height of the building is of 244.95 feet.
