enter your response here square feet
(Simplify your answer.)
(a) Christine will decompose the shape into 2 trapezoid
(b) Christine will need 29 square feet area of carpet
How to evaluate for the area of the trapezoid.area of the trapezoid is calculated using the formula: 1/2 × (AB + CD) × height, where AB and CD are the lengths of its parallel sides.
(a). The shape will be decomposed into two (2) trapezoid
(b). For the bigger trapezoid;
8ft 6in = 8.5 ft
area of bigger trapezoid = 1/2 × (8.5 + 12) × 2 ft²
area of bigger trapezoid = 20.5 ft²
For the smaller trapezoid;
2ft 6in = 2.5 ft
area of smaller trapezoid = 1/2 × (2.5 + 6) × 2 ft²
area of smaller trapezoid = 8.5 ft²
Total square feet area of carpet = 20.5 ft² + 8.5 ft²
Total square feet area of carpet = 29 ft²
Therefore, (a) Christine will decompose the shape into 2 trapezoid
(b) Christine will need 29 square feet area of carpet

please help me out with this problem, i'd really appreciate it
Answer:
Step-by-step explanation:
let amount of nickels = y
then amount of quarters = 12-y
let amount of dimes = 2y
according to given condition,
Total amount = y+12-y+2y
we will +y and -y because of different signs,(+,- = -).
10.60 = 12+2y
12-10.60 = 2y
2.60=2y
using / as division sign,
y=2.60/2
y = 1.30
amount of quarters = 1.30
amount of nickels = 12-y
= 12-1.30
= 10.70
amount of dimes = 2y
=2(1.30)
=2.60

How many degrees is angle 7?
Answer:
42°
Step-by-step explanation:
This is defined as a transversal in geometry, where one line intersects two straight lines.
It is given that one of the angles is 42°. Let the angle that measure 42° be denoted as ∠42.
∠4 ≅ ∠42 based on the alternate interior angles theorem.
∠4 ≅ ∠7 based on the vertical angles theorem.
Therefore, ∠42 ≅ ∠7 based on CPCTC.
Therefore,
m∠7 = 42°.

I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter. How old am I now?
Answer:
65 years old.
Step-by-step explanation:
Define the variables:
Let x be the age of the granddaughter.Let y be the age of the grandparent.Given:
I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter.Create two equations with the given information and defined variables:
\(\begin{cases}y = 13x\\y + 1 = 11(x + 1)\end{cases}\)
Substitute the first equation into the second equation and solve for x:
\(\implies 13x+1=11(x+1)\)
\(\implies 13x+1=11x+11\)
\(\implies 2x=10\)
\(\implies x=5\)
Substitute the found value of x into the first equation and solve for y:
\(\implies y=13(5)\)
\(\implies y=65\)
Therefore, the age of the grandparent now is 65 years.
Given statements:
I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter.Let us represent the character's age by variables. Assuming that the grandparent's age is G and the granddaughter's age is D. Now, using the obtained variables and the statements, create two equations that represents the provided statements. Then, we can compare the equations and simplify if needed to determine the value of the variables.
\(\implies \left[\begin{array}{ccc} \text{G = 13D} \\ \text{G + 1 = 11(D + 1)}\\\end{array}\right]\)
Since G = 13D is in the form of direct variation, we can substitute the value of G into the second equation to determine the value of D (the age of the granddaughter). Then, we can substitute the value of D into any of the two equations to determine the age of the grandparent.
⇒ G + 1 = 11(D + 1)⇒ G + 1 = 11(D + 1) [G = 13D]⇒ 13D + 1 = 11(D + 1)To solve for D, simplify both sides of the equation by using the distributive property. We need to simplify both sides of the equation so that we can isolate the variables on the other side of the equation.
⇒ 13D + 1 = 11(D + 1)⇒ 13D + 1 = 11D + 11Isolate the variables on one side. This step is necessary because it can cancel out the extra variable and simplify the other variable. To do this, you can either add or subtract on both sides of the equation.
Note: I am subtracting 11D on both sides of the equation since it is my preference. But you can also subtract 13D on both sides of the equation.
⇒ 13D + 1 - 11D = 11D + 11 - 11D⇒ 1 + 2D = 11To further isolate 2D, we need to subtract 1 on both sides of the equation to cancel out the 1 on the left-hand side of the equation. Then, we have:
⇒ 1 + 2D - 1 = 11 - 1⇒ 2D = 10But the variable is still not completely isolated since there is a coefficient being multiplied to D. To isolate the coefficient from the variable, we will need to divide the coefficient (2) on both sides of the equation.
⇒ 2D = 10⇒ 2D/2 = 10/2Then, simplify both sides of the equation. Eventually, we will have a variable on one side and a numerical value on the other side.
⇒ 2D/2 = 10/2⇒ D = 5Now we know the age of the granddaughter, we can substitute the age of the granddaughter into one of the equations and simplify it to determine the age of the grandparent. I am going to choose G = 13D since it is easier to simplify. Then, we will substitute the value of D into the equation.
⇒ G = 13D ⇒ G = 13(5)⇒ G = 65 yearsTherefore, the age of the grandparent is 65 years.
A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day

(3m)^-3 / (1n)^-3To get rid of the fact that th exponents are negative, we can flip the fraction!(1n)^3 / (3m)^3Now we distribute the exponent to the numbers and variables1n^3 / 27m^3That is your example answer for #9. 10. -(2a)^-2 b°Anything to the power of 0 is 1. -(2a)^-2Since we have a negative exponent, flip the fraction-(1/(2a)^2)-1/4a^2That is your example answer for 10. 11) 2m^-1/3(ab)^-4c^-7Flip the exponents with negative powers to make it positive2(ab)^4 c^7 / 3mdistribute the 4 exponent 2a^4b^4c^7/3mThat is your example answer for 11. 12) 4 x y^-1 z^0 / v^-3Anything to the power of 0 is 1. 4 x y^-1 / v^-3Flip the variables that have a negative exponent. 4xv^3/yThat is your example answer for 12

Tyshawna and Jean both work at a sneaker store and make a fifthteen dollar commission for every sneaker sold. However, Jean makes a flat rate of 75 dollars a day because he has been working at the store longer than Tyshawna. Tyshawna makes a flat rate of 65 dollars a day.
(a. Will Tyshawn and Jean ever make the same amount of money in a day? Why or why not?
Answer:
Since Jean makes a higher flat rate than Tyshawna, they won't make the same amount in a day. Jean makes a flat rate of 75 dollars a day, while Tyshawna makes a flat rate of 65 dollars a day. Tyshawna is only a few flat rates behind. Although it would seem like they could make the same amount, they wouldn't be able to. If they both had the same flat rate, they would be making the same amount almost everyday.
I hope I helped :)
Answer:
yes, because the total pay is based on how many shoes are sold and not how long one has been there so if Tyshawna sells more shoes her or his pay rate will rise.

Six of the seven data items in a data set are 19, 20, 22, 14, 17, and 11. The median of this data set is 19. If x is the seventh value, which of the following statements is true?
Answers are:
x is less than 19
x is greater than 19
x is ≤ 19
x is ≥ 19
Answer:
B. x is greater than 19
Step-by-step explanation:
The first thing you want to do is organize the values from smallest to largest.
11, 14, 17, 19, 20, 22
If x is your 7th term, then it comes after the 6th term, 22. If we continue to follow the pattern of increase, then x must be greater than 19.
One out of every 9 light bulbs is defective.
What constant of proportionality relates defective bulbs to total bulbs?
The constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.
What is Constant Proportionality?The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality. Constant ratio, constant rate, unit rate, constant of variation, and even rate of change are other names for the constant of proportionality.
Given:
One out of every 9 light bulbs is defective.
Total bulbs = 9
So, Defective bulbs = 1
Thus, Constant of proportionality = Defective bulbs / Total bulbs.
Constant of proportionality = 1 / 9
Hence, the constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.

d. using the whole number of π makes the calculation easier but using the π with more decimals will make the result more accurate.
Step-by-step explanation:
Diameter = 10 => radius = 10/2 = 5
Circumference: C = 2πr = 2π(5) = 10π
