Answers
Answer:
(x - 4)(x + 3)
Step-by-step explanation:
Given
x² - x - 12
Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (- 1)
The factors are - 4 and + 3, since
- 4 × + 3 = - 12 and - 4 + 3 = - 1, then
x² - x - 12 = (x - 4)(x + 3) ← in factored form

The set for a school play needs a replica of a historic building painted on a backdrop that is 20 feet long and 16 feet high. The actual building measures 320 feet long by 256 feet high. A stage crewmember writes (x, y) arrow right ( 1/20 x, 1/20y) to represent the dilation. Is the crewmember's calculation correct if the painted replica is to cover the entire backdrop? Complete the explanation.
Answers
Answer:
Stage crewmember's calculation is incorrect
Correct = 1/16x 1/16y
Step-by-step explanation:
Given that:
Dimension of backdrop : 20 feets long ; 16 feets high
Actual dimension of building : 320 feets long ; 256 feets high
The correct scale factor can be obtained thus :
Ratio of backdrop dimension to the actual dimension of building
Length : 20 / 320 = 1 /16
Height : 16 / 256 = 1/16
Hence, stage crewmember's calculation of (1/20x ; 1/20y) is incorrect.

Answer:
M = K =
101°Step-by-step explanation:
M = K, because it's a kite.
Kite has 2 angles on the left and right, each with the same size,The kite also has different angles at the other angle points.(Addition of kite angles result in 360°)
Therefore
360 = 63 + 95 + 2M
2M = 360-63-95
2M = 202
M = 202÷2
M = K = 101°
The size of each angle M and angle K = 101 degrees.

The sum of the speeds of two trains is 723.1 miles per hour. If the speed of the first train is 10.9 mph faster than that of the second train, find the speeds of each.
What is the speed of the first train?
Answers
9514 1404 393
Answer:
367 miles per hour
Step-by-step explanation:
The speed of the faster train is half the total plus half the difference:
s1 = (723.1 +10.9)/2 = 367 . . . . miles per hour
_____
Check
The slower train is 367-10.9 = 356.1, and the total is 723.1 mph, as required.
_____
If you want an equation, you can let x represent the faster speed. Then the total is ...
x + (x -10.9) = 723.1
2x = 723.1 +10.9
x = (723.1 +10.9)/2 = 367

First open the parentheses by applying the distributive property.
To do this, multiply each term you have inside (-3x⅔ + 5x + 7) by -1.
Thus, you would have the following:

Add like terms

Answer for question 2 is What is 18 percent (calculated percentage %) of number 32? Answer: 5.76.
hope it helps. Please mark me Brainleist please.
Answer:
1. 40%
2. 56.25%
Step-by-step explanation:
1. N% of 15 = 6
N/100 x 15 =6
N = (6 × 100)/15
N = 40
2.N% of 32 = 18
N/100 x 32 = 18
N = (18 x 100) /32
N= 56.25
Leah spent 1 hour 32 minutes less than Carl reading last week. Carl spent 51 minutes less than Pete. Pete spent 3 hours reading. How long did Leah spend reading?
Answers
Answer:
37 minutes
Step-by-step explanation:
Carl spent 51 minutes less than Pete, so subtract.
3 hours = 180 minutes
180 - 51 = 129 minutes = 2 hours and 9 minutes
And Leah spent 1 hour 32 minutes less than Carl, so subtract again.
1 hour = 60 minutes + 32 = 92 minutes
129 - 92 = 37 minutes.

There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 reds?
Answers
Answer: The probability of getting two red marbles is P = 0.141
Step-by-step explanation:
We know that in the bag there are 3 blue marbles and 5 red marbles, then there is a total of 8 marbles in the bag.
The probability of taking at random a red marble is equal to the quotient between the number of red marbles and the total number of marbles, this is:
p = 3/8
Suppose we got a red marble:
Now we replace the red marble we took, so in the bag there are again 3 red marbles and 8 total marbles, then the probability of getting another red marble is again:
q = 3/8
The joint probability (this is, the probability of both events happening) is equal to the product of the individual probabilities, with gives us:
P = p*q = (3/8)*(3/8) = 9/64 = 0.141
The people of Bridgetown wanted to build a bridge across a nearby river. Since they were poor swimmers, their master Trigonomos agreed to measure the width of the river without actually crossing it. Trigonomos spotted a tree across the river and marked the spot directly across from it. Then he walked to another point 151515 meters down the river and found that the angle between his side of the river and the line connecting him to the tree was 76^\circ76 ∘ 76, degrees. What is the width of the river?
Answers
Answer:
60.16 m
Step-by-step explanation:
Let w = width of river
Using trigonometry :
The width, w of the river is can be calculated thus :
Tan θ = opposite / Adjacent
Tan 76 = w / 15
4.0107809 = w / 15
w = 15 * 4.0107809
w = 60.1617 m
Hence, width of the river is 60.16 m
The length of a 1-inch paperclip is about 1.6 x 10−5 miles. It takes about 1.5 x 1010 paperclips linked together to reach the moon. What is the approximate distance to the moon?
A. 3.1x 10^5 miles
B. 2.4 x 10^-2 miles
C. 3.1x10^-2 miles
D. 2.4 x 10^5 miles
Answers
Answer:
D. 2.4 x 10⁵ miles.
Step-by-step explanation:
Given;
length of 1-inch paperclip, L= 1.6 x 10⁻⁵ miles
number of paperclips linked together to reach the moon, n = 1.5 x 10¹⁰
The approximate distance to the moon is calculated as follows;
distance to the moon, d = L x n
distance to the moon, d = 1.6 x 10⁻⁵ miles x 1.5 x 10¹⁰
distance to the moon, d = 2.4 x 10⁵ miles
Therefore, the approximate distance to the moon is 2.4 x 10⁵ miles.
The correct option is D.

Answers
Answer:
(3 and 15)
Step-by-step explanation:
If the product of both of these two numbers needs to be a negative 45 then there are no pair of integers that comply with both requirements.
If the multiplication in the question is wrong and it is a positive 45 then the pair of integers that would comply with these requirements would be (3 and 15). Multiplying this pair together would give you 45 and the difference between them is also 12 meaning it complies with both requirements that were asked for in the question.
