Answer:
Total wood required for the project will be 9 3/8 feet.
Step-by-step explanation:
As given in the question Quentin has lumber of length = 6 5/8
feet =53/8 feet.
Now Quentin needs more lumber = 2 3/4 feet =11/4 feet or 22/8 feet.
So we can get total wood required by adding these two figures
That is = 53/8 + 22/8
= (53 +22)/8
= 75/8
= 9 3/8 feet
Answer:
[tex]The\ total\ wood\ will\ the\ project\ have\ used\ be\ 9 \frac{3}{8}.[/tex]
Step-by-step explanation:
As given
[tex]Quentin\ has\ 6 \frac{5}{8}\ feet\ of\ lumber\ but\ needs\ another\ 2 \frac{3}{4}\ feet\ to\ complete\ the\ project\ he's\ working\ on.[/tex]
i.e
[tex]Quentin\ has\ \frac{53}{8}\ feet\ of\ lumber\ but\ needs\ another\ \frac{11}{4}\ feet\ to\ complete\ the\ project\ he's\ working\ on.[/tex]
[tex]Total\ wood\ will\ the\ project\ have\ used =\frac{53}{8} + \frac{11}{4}[/tex]
L.C.M of (8,4) = 8
Than
[tex]Total\ wood\ will\ the\ project\ have\ used =\frac{53 + 11\times 2}{8}[/tex]
[tex]Total\ wood\ will\ the\ project\ have\ used =\frac{53 + 22}{8}[/tex] [tex]Total\ wood\ will\ the\ project\ have\ used =\frac{75}{8}[/tex]
[tex]Total\ wood\ will\ the\ project\ have\ used = 9 \frac{3}{8}[/tex]

You have performed increasingly well this past year and you are earning a 6% pay increase to your current $62,900 annual salary."
To calculate a new salary after a pay increase, multiply the current salary by the percentage increase and add it to the original salary. In this case, a 6% increase on a $62,900 salary results in a new annual salary of $66,674.
Explanation:The subject of this question is determining the new salary after a pay increase, which is a common problem in mathematics related to percentages. To calculate the new salary after a 6% pay increase to a current salary of $62,900, you multiply the current salary by the percentage increase in decimal form, which is 0.06.
Step-by-Step Calculation
Determine the increase amount by multiplying the current salary by the percentage increase: $62,900 × 0.06 = $3,774.
Add the increase to the current salary to get the new salary: $62,900 + $3,774 = $66,674.
The new annual salary after a 6% increase will therefore be $66,674.
To generalize, the formula to calculate the percentage change or growth rate is given by:
Percentage change = (Change in quantity / Original Quantity) × 100
For example, a $2 per hour raise on a $10 per hour job represents
Percentage change = ($2 / $10) × 100 = 20%

Three times one number plus a second number is 40, and the one number minus the second number is 4. Find the numbers.
Answer:
The numbers are 11 and 7
Step-by-step explanation:
To find these, use the statements to create equations in standard form.
3x + y = 40
x - y = 4
Now that we have these two, we can add them together and get the y's to cancel out.
3x + y = 40
x - y = 4
-------------------
4x = 44
x = 11
Now that we have the first number as 11, we can solve for y using either equation.
x - y = 4
11 - y = 4
-y = -7
y = 7

Calculate the value of the exterior angle
10
95
3.57
1.4
Answer:
95
Step-by-step explanation:
We have been given a diagram triangle in which measurement of few angles in terms of x are given.
Using those we need to find the exterior angle but before that we need to find the value of x.
We know that exterior angle is equal to sum of two distant interior angles of that triangle so we can write:
(8x+15)=(3x+20)+(4x+5)
8x+15=3x+20+4x+5
8x+15=7x+25
8x-7x=25-15
x=10
Now plug x=10 into exterior angle 8x+15
8x+15=8*10+15=80+15=95
Hence final answer is 95.
One number is 3 less than twice another. If their sum is 39, find the numbers.
Which of the following systems of equations represents the word problem?
y = 2x - 3 and y = x + 39
y = 2x - 3 and x + y = 39
y = 2(x - 3) and x + y = 39
Answer with Step-by-step explanation:
Let x and y be two numbers.
One number is 3 less than twice another.
⇒ y=2x-3
Their sum is 39.
⇒ x+y=39
Hence, system of equations are:
y = 2x - 3 and x + y = 39
Putting y=2x-3 in x+y=39
x+2x-3=39
⇒ 3x-3=39
⇒ x-1=13 (dividing both sides by 3)
⇒ x=14
y=2x-3
⇒ y=2×14-3
⇒ y=28-3
⇒ y=25
Hence, Two numbers are:

Andy Taylor and Ben share their team payment in the ratio 1:3:4. What percentage of the total does Andy recieve?
Answer:
12.5%
Step-by-step explanation:
sum the parts of the ratio 1 + 3 + 4 = 8 parts
8 parts represents 100%, hence
1 part = [tex]\frac{100}{8}[/tex] = 12.5% ← Andy's percentage of the total
Andy Taylor's share in the ratio of 1:3:4 results in him receiving 12.5% of the total team payment.
Explanation:The question is about the sharing of a total team payment between Andy Taylor and Ben in the ratio of 1:3:4. To find out what percentage Andy receives, we first need to establish the total parts in the ratio. The ratio 1:3:4 sums up to 8 parts in total. Andy's share is represented by 1 part out of these 8. To find the percentage, we divide Andy's 1 part by the total 8 parts, multiply by 100, giving us 12.5%. This means that Andy receives 12.5% of the total team payment.

Tax returns filed manually have a 20% chance of containing errors, while tax returns filed electronically have a 0.05% chance of containing the same. If 2.7 million tax returns are filed each way, how many more erroneous manually filed returns will there be than erroneous electronically filed returns? a. 270,675 b. 538,650 c. 541,350 d. 269,325
Answer:
B) 538, 650
Step-by-step explanation:
Given:
Errors on tax returns filed manually = 20%
Errors on tax returns filed electronically = 0.05%
Tax return filled in each way = 2.7 million
Manual filing:
2,700,000 x 20% = 2,700,000*0.2 = 540,000
Electronic filing:
2,700,000 x 0.05% = 2, 700,000*0.0005 = 1,350
Error difference = 540,000 - 1,350 = 538,650
There will be 538,650 more erroneous tax returns filed manually than there are filed electronically.

The measurement, y, varies directly with regard to another value, x. If y = 9 and x = 24, find x for y = 25.
Answer:
x=66.667
Step-by-step explanation:
Basically, if y varies directly with a value x, you get an equation of the form y=kx, where k is a constant. To answer the question, first substitute 9 into y, and 24 into x.
9=24k
k=0.375
k is 0.375, so to get x, substitute 0.375 into k and 25 into y
25=0.375x
x=66.667
And we got it!
Final answer:
To find x when y = 25 in a direct variation where y = 9 when x = 24, first find the constant of proportionality (k = 3/8), then use this constant to solve the equation 25 = (3/8)x which yields x ≈ 66.67.
Explanation:
The student's question concerns direct variation, which is a concept where one variable changes in proportion to another variable. In this particular problem, the measure y varies directly with x. Given that y = 9 when x = 24, we can use this information to establish the constant of proportionality k where y = kx.
First, we solve for k using the initial condition:
9 = k * 24
k = 9/24
k = 3/8
Now that we have the constant of proportionality, we can find x when y = 25 by setting up the equation:
25 = (3/8)x
x = 25 * (8/3)
x = 200/3
x ≈ 66.67
Therefore, when y = 25, the value of x is approximately 66.67.
Which equation shows a line perpendicular to the line
Answer:
The second answer: y= 3/4x + 2
Step-by-step explanation:
Subtract 4x to the other side
Divide by 3 to get y by itself

The new pentagon has a perimeter of 27 centimeters.
Explanation:To find the perimeter of a regular pentagon, we multiply the length of one side by the number of sides. In this case, the perimeter is 18 centimeters, so each side of the pentagon is 18/5 = 3.6 centimeters long.
When this pentagon is dilated by a scale factor of 3/2, each side of the new pentagon will be 3/2 x 3.6 = 5.4 centimeters long.
Therefore, the new pentagon has a perimeter of 5.4 x 5 = 27 centimeters.

A patient is given a 100-milligram dosage of a drug that decays exponentially at a rate of 11% per hour. The doctor wants to know when 15 milligrams of the drug remains.
Write an equation that models the situation. Explain each aspect of your equation.
Answer:
16.3 hours.
Step-by-step explanation:
"Decays exponentially at a rate of 11% per hour" translates into
(1 - 0.11)^h, where h is the number of hours during which the drug decays.
The negative sign comes from "decay."
The complete formula applicable here is
d(h) = (100 mg)(1 - 0.11)^h, where h is the number of hours.
We want to know how many hours it will be until all but 15 mg remain. The appropriate formula for this is
15 mg = (100 mg)()^h. Dividing both sides by 100 mg, we get:
15 mg
------------- = 0.89^h, or 0.15 = 1.11^h
100 mg
Apply properties of logs to solve this. Take the natural log of both sides of the above equation. We get:
ln 0.15 = h(ln 0.89). Dividing both sides by ln 0.89, we get:
h = 16.3
The original 100 mg dosage would decay to 15 mg after 16.3 hours.

Answer:
The no. of adult's tickets sold is 25.
The no. of adult's tickets sold is 247
Step-by-step explanation:
Given :
Tickets for a basketball game cost $2 for students and $5 for adults.
The number of students was 3 less than 10 times the number of adults.
The total amount of money from ticket sales was $619.
To Find : No. of each ticket were sold
Solution :
Let x be the no. of the student's tickets sold
Let y be the no. of adult's tickets sold
Since we are given that The number of students was 3 less than 10 times the number of adults.
⇒ x = 10y -3 --(A)
Now cost of 1 student's ticket is $2
Thus, cost of x student's ticket is $2x
Now cost of 1 adult's ticket is $5
Thus,cost of y adult's ticket is $5y
Since we are given that the total amount of money from ticket sales was $619.
⇒2x +5y =619 ---(B)
Solving equation A and B by substitution method :
putting value of x from (A) in (B)
We get :
⇒2( 10y -3) +5y =619
⇒20y-6+5y= 619
⇒25y = 625
⇒y = 625/25
⇒y=25
Thus, the no. of adult's tickets sold is 25.
Putting value of y in equation A to get value of x .
⇒x = 10(25) -3
⇒x = 247
Thus the no. of adult's tickets sold is 247

Rita spends 52% of her pocket money on magazines and 23% on movies. If her pocket money was RS.144 what amount of her pocket money is left
Answer:
The amount of Rita's pocket money left is Rs. 36.
Step-by-step explanation:
Pocket money that Rita had before = 144
Money spent for magazines = 52% of 144
= [tex]\frac{52}{100} (144)[/tex]
= 0.52(144)
= 74.88
Money spent for movies = 23% of 144
= [tex]\frac{23}{100} (144)[/tex]
= 0.23(144)
= 33.12
Money left with Rita = 144 - (74.88 + 33.12)
= 144 - 108
= 36
Hence, Rita left with Rs. 36.
Aliter:
Total money spent = (52 + 23)% = 75%
So, money left with Rita = 100 - 75 = 25%
25% of 144 = 0.25(144) = 36.

Which value of y is a solution of the inequality? 2y+9≤11
y = 1
y = 2
y = 11
y = 9
Answer:
y=1 for [tex]y\leq 1[/tex]
Step-by-step explanation:
We can solve an inequality much like we solve an equation. We will use inverse operations to isolate y. If we need to divide by a negative then we will need to flip the inequality.
[tex]2y+9\leq 11\\2y+9-9\leq 11-9\\2y\leq 2\\\frac{2y}{2}\leq \frac{2}{2} \\y\leq 1[/tex]
First, we moved 9 across the equal sign to combine it with 11 by subtracting by 9 from both sides.
Second, we divided both sides by 2.
[tex]y\leq 1[/tex] is the solution. All solutions equal to 1 and less than 1 will work.
