Which expression represents x2−12x+36 in factored form? (x−4)(x−9) (x+6)2 (x+6)(x−6) (x−6)2
Two factors of x²-12x+36 are
(x-6) and (x-6)
Solution;
x²-12x +36
x²-6x -6x +36 ( split -12x in two parts such that if add them we will get-12x and if multiply will get 36x²)
Taking x common from first two terms and 6 from next two terms
x(x-6) -6(x -6)
taking (x-6) common
(x-6)(x-6)
Answer:
[tex]x^2 - 12x + 36 = (x-6)(x-6) = (x-6)^2[/tex]
Step-by-step explanation:
We are given the following expression:
[tex]x^2 - 12x + 36[/tex]
We need to factor the given expression.
We will do this with the help of technique of splitting the middle term.
Factorization can be done as:
[tex]x^2-12x + 36\\=x^2 - 6x-6x+36\\=x(x-6)-6(x-6)\\=(x-6)(x-6)\\=(x-6)^2[/tex]
Thus, the factored form of given expression is:
[tex]x^2 - 12x + 36 = (x-6)(x-6) = (x-6)^2[/tex]

The number of seconds in a 40-hour work week can be calculated as follows:
40hrs*60mins/1hr=2400mins
2400mins*60secs/min=144,000secs
First we can calculate how many seconds there are in an hour:
Since 1 hour has 60 minutes and each minute has 60 seconds.
Then 1 hour = 60 minutes * 60 seconds/1minute = 3,600 seconds.
Now we have to multiply x 40 to calculate how many seconds there are in 40 hours.
In a 40-hour work week = 40 hours * 3,600 seconds/1hour = 144,000 seconds
Answer : 144,000 seconds there are in a 40-hour work week

Therefore, correct option is C.
Use the Law of Sines to find the missing angle of the triangle.
Find m∠C to the nearest tenth.
Answers
C = 58.84
B = 97.16°
Explanation
The sine rule states:
SinA/a = sinB/b
∴ sin24 / 77 = sinC / 162
sinC = (162 × sin24)/77
= 65.89/77
= 0.85573
C = 58.84°
Angles in a triangle add up to 180°
∴ B + 24 + 58.84 = 180
B = 180 - 24 - 58.84
= 180 - 82.84
= 97.16°
=
Using the Law of Sines, which states that the ratio of a side length to the sine of its opposite angle is the same for all sides, you can solve for the missing angle. Rearrange the formula to sinC = c * sinA / a, then take the inverse sine of both sides to find the measure of the missing angle.
Explanation:To find the missing angle m∠C using the Law of Sines, you first need to know the lengths of the sides of the triangle and one of the angles. The Law of Sines states that the ratio of the length of a side of a triangle to the sine of its opposite angle is the same for all three sides of the triangle. In other words, if a, b, and c represent the lengths of the sides and A, B, and C represent the measures of the opposite angles, we have: sinA/a = sinB/b = sinC/c.
To solve for m∠C, you rearrange the Law of Sines to: sinC = c * sinA / a. After that you take the inverse sine (or arcsin) of both sides to find m∠C = arcsin(c * sinA / a). Notice that you are assuming that the sine of the missing angle is positive, which is valid for angles less than 180 degrees.

a.36meters
b.54meters
c.24meters
d.18meters
e.40meters
The fencing that is needed to enclose the garden is 36 meters.
Let the width be represented by x.
Let the length be represented by x+2.
The area is given as 80m².
Therefore, the length and width will be calculated thus;
x(x + 2) = 80
x² + 2x - 80 = 0
x² + 10x - 8x - 80 = 0
x(x + 10) - 8(x + 10) = 0
x - 8 = 0
x = 8

To prepare for a wedding, Aiden bought 60 candles . He paid $0.37 for each candle . His sister bought 170 candles at a sale where paid $0.05 less for each candle than Aiden did.
Aiden spent $22.20 on 60 candles. His sister spent $54.40 on 170 candles, $32.20 more than Aiden.
Let's break this down step by step:
a. To find out how much Aiden spent on candles, we multiply the number of candles he bought (60) by the price per candle ($0.37):
Total cost for Aiden = 60 × $0.37 = $22.20
So, Aiden spent $22.20 on candles.
b. Aiden's sister bought 170 candles and paid $0.05 less per candle than Aiden did. This means she paid $0.37 - $0.05 = $0.32 per candle.
To find out how much Aiden's sister spent on candles, we multiply the number of candles she bought (170) by the price per candle ($0.32):
Total cost for Aiden's sister = 170 × $0.32 = $54.40
So, Aiden's sister spent $54.40 on candles.
c. To compare who spent more on candles, we simply compare the total costs. Aiden spent $22.20 and his sister spent $54.40.
Aiden's sister spent more. To find out how much more she spent, we subtract Aiden's total from his sister's:
$54.40 - $22.20 = $32.20
So, Aiden's sister spent $32.20 more on candles than Aiden did.
The complete question is here:
To prepare for a wedding, Aiden bought 60 candles. He paid $0.37 for each candle. His sister bought 170 candles at a sale where she paid $0.05 less for each candle than Aiden did.
a. How much did Aiden spend on candles?

There are 20 cards labeled from 1 to 20 in a bag. A card is randomly selected from the bag.
What is the probability of getting an even number or a 1?
9/20
11/20
1/2
3/5
Answer:
option 2=11/20 is the answer.
Step-by-step explanation:
given that there are 20 cards numbers 1,2... 20.
A card is randomly drawn.
We have to find the probability of drawing either 1 or even card.
P(drawing even card) = no of even cards/total cards = 10/20= 0.5
P(drawing one) = no of 1's/total cards = 1/20 = 0.05
P(drawing both one and even card) = 0 (since impossible)
Hence P(drawing even or one) =0.5+0.05-0
=0.55
= 11/20
Hence option 2 is the answer.
Answer : 11/20
There are 20 cards labeled from 1 to 20 in a bag. A card is randomly selected from the bag.
Total number of outcomes = 20
outcomes of an even number ={2,4,6,8,10,12,14,16,18,20}
So number of outcomes of even number = 10
outcomes of a 1 ={1}
So number of outcomes of a 1 = 1
Number of outcomes of even number and a 1 = 10+1 = 11
Probability ( any event) =number of favorable outcomes divide by total number of outcomes
Probability (getting an even number or a 1) = [tex]\frac{11}{20}[/tex]

the temperature dropped from 80°F to 70°F. what is the percent drop in temperature?
Final answer:
The percent drop in temperature from 80°F to 70°F is calculated as (10°F / 80°F) × 100%, which equals 12.5%.
Explanation:
To find the percent drop in temperature from 80°F to 70°F, we need to calculate the decrease in temperature and then express that decrease as a percentage of the original temperature. The decrease in temperature is 80°F - 70°F = 10°F. To find the percent drop, we use the formula for percentage change, which is (Change/Original) × 100%.
Therefore, the percent drop = (10°F / 80°F) × 100% = 12.5%. So, the temperature dropped by 12.5% from 80°F to 70°F.
Final answer:
To find the percent drop in temperature from 80°F to 70°F, calculate the difference between the temperatures and divide by the original temperature, then multiply by 100%. The result is a 12.5% decrease in temperature.
Explanation:
The question asks to find the percent drop in temperature when it drops from 80°F to 70°F. To calculate this, we use the formula for percent decrease, which is (original value - new value) / original value × 100%. Applying this formula, the original temperature is 80°F, and the new temperature is 70°F.
(80°F - 70°F) / 80°F × 100% = 10°F / 80°F × 100% = 0.125 × 100% = 12.5%.
Therefore, the temperature dropped by 12.5% when it fell from 80°F to 70°F.

Question: The table below shows the number of times the dishwasher was used in three different houses over three days.
-On Friday, 17.5 total gallons of water were used. On Saturday, 31.5 total gallons were used. On Sunday, 24.75 total gallons were used. What is the difference between the water use per load of the dishwasher that uses the most water and the dishwasher that uses the least water?
A. 0.5 gallon
B. 0.75 gallon
C. 3 gallons
D. 4 gallons
WILL MARK BRAINLIEST! Picture below.
Answer:
Option B. 0.75 gallons is the right answer.
Step-by-step explanation:
Let the load of dishwasher used in house A = x gallons
Let the load of dishwasher used in house B is = y gallons
and similarly we assume for house C = z gallons
Now from the given question
On Friday amount of water used in all three houses = 17.5 gallons
From the table we will make the equation
x + 2y + 2z = 17.5-----(1)
For Saturday
2x + 3y + 4z = 31.5 ----(2)
For Sunday
2x + 2y + 3z = 24.75 -----(3)
By subtracting equation 3 from 2
y + z = 31.5 - 24.75 = 6.75 ------(4)
Equation (1) multiplied by 2 - equation (2)
2×(x + 2y + 2z) - (2x + 3y + 4z) = 17.5×2 - 31.5
y = 35 - 31.5 = 3.5
By putting y = 3.5 in the equation (4)
z = 6.75 - 3.5 = 3.25
By putting y = 3.5 and z = 3.25 in the equation (1)
x + 7 + 6.5 = 17.5
x = 17.5 - 13.5 = 4
Now the difference between load of dishwasher that uses least water and the most.
x - z = 4 - 3.25 = 0.75 gallons
Option B is the right answer.
Answer:
Option B. 0.75 gallons is the right answer.

Victor baked 30 chocolate chip cookies, 18 peanut butter cookies, and 24 sugar cookies. He wants to split them into equal identical bags to sell at the bake sale. What is the greatest number bags of cookies Victor can make?
Answer:
6
Step-by-step explanation:
The greatest common factor (GCF) of 18, 24, and 30 is 6.
Victor can make at most 6 bags with equal numbers of each type of cookie.
_____
18 = 6×3
24 = 6×4
30 = 6×5
One way to look for the GCF is to consider the differences between the numbers. The smallest difference between any pair is 6, which also divides all of the numbers evenly. Hence 6 is the GCF.
By finding the greatest common divisor (GCD) of the counts of each type of cookie (30, 18, 24), it is determined that Victor can make 6 identical bags for the bake sale.
Explanation:To determine the greatest number of bags Victor can make, we need to find the greatest common divisor (GCD) of the counts of each type of cookie: 30 chocolate chip cookies, 18 peanut butter cookies and 24 sugar cookies. The GCD is the largest number that exactly divides all these counts.
First, list the divisors of each number:
Divisors of 30: 1, 2, 3, 5, 6, 10, 15, 30 Divisors of 18: 1, 2, 3, 6, 9, 18 Divisors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Find the highest number that appears in each list. The highest common factor of 30, 18, and 24 is 6, so Victor can make a total of 6 equal bags with each type of cookie.
