What is the quotient of −112÷2 1/3 ?
Answer:
-48
Step-by-step explanation:
−112÷2 1/3 needs to be rewritten as -112 / (7/3), where 7/3 is the improper fraction version of 2 1/3.
Then we have
-112
---------
7/3
Recall that division by a fraction is equivalent to multiplication by the reciprocal of the fraction; thus, the above expression becomes
-112 * 3
-----------
7
This, in turn, can be reduced through division to -16*3, which equals -48.

Decide if the following statement is true or false. A simple random sample of twelve 2+ bedroom houses in Rockingham County has a mean monthly lease of $695 with a standard deviation of $135. The true rental cost will be from $560 to $830
Answer:
Step-by-step explanation:

The given statement is "False" because the statement's range is based on the mean and standard deviation of a simple random sample of houses, not the whole population of Rockingham County's houses..
What is a simple random sample?A simple random sample is a subset of a population chosen in a way that gives each member of the population an equal chance of being selected. The mean and standard deviation of a simple random sample provides information about the population from which the sample was drawn, but they do not provide a range in which the true value of a population parameter is guaranteed to fall.
In this case, the statement provides a range for the true rental cost of 2+ bedroom houses in Rockingham County, but there is no guarantee that the true rental cost will fall within this range. The range provided in the statement is based on the mean and standard deviation of a simple random sample of houses, not the entire population of houses in Rockingham County.
Hence, the given statement is False.

Which is the coordinate of point A?
(8, –6)
(–6, 8)
(6, –8)
(–8, –6)
Answer:
Option A is your definite answer.
Step-by-step explanation:
We know that the x coordinate is positive since it is on the positive half of the x-axis. We also can identify that the point A is in the 4th Quarter of the grid, so the y coordinate is negative.
The only choice that proves this reasoning true is option A :)

The highest common factor (HCF) of two numbers is 6.
The lowest common multiple (LCM) of the same numbers is 60
What are the two numbers?
Please explain every step
Answer:
12 and 30
Step-by-step explanation:
HCF = 6 = 2×3 means they both have in common a factor of 2 and a factor of 3, but at least one of the numbers has no more than one of each of these factors.LCM= 60=2²×3×5 means That the combined product of their factors counting only once the ones they have in common is 60.so they could be 2×2×3 = 12 and 2×3×5 = 30

2 ⅒
Answer:
2 1/10
Step-by-step explanation:
To convert the decimal 2.1 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
2.1 = 2.1
--------
1
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,
= (2.1 × 10)
(1 × 10) = 21
------
10
Now you have to simplify, 2 1/10.

y = 6.5x + 75.5
Which statement below best interprets the slope in the context of the problem?
Answer:
proof: answer is 2/13
1 / 6.5 = m
m = 0.153846154
10/65 = m
m = 2/13
2/13 = m
m = 0.153846154
Therefore we could show multiplication proof
m = 10/65 = m = 2/13
2 x 5 = 10
13 x 5 = 65
Step-by-step explanation:
See attached graph of y = 6.5x+75.5
plotting the graph
1. Mark y intercept at 75.5 as given in the equation
2. find the slope to whole numbers
m = 10 across / 65 across = 6.5 slope
Mapping Pythagoras 10^2 +65^2 = c^2
sqrt 100 + sqrt 4225 = c^2
c^2 = sqrt 4225 = 65.7647322 = 65.8
0.7647322 / 65 = 0.0117651108 = 100th
65 + 0.0117651108 = 65.011765.....
Therefore 10 across / 65.0118 down
or 10 across / 65 down is another way to graph, as seen on graph.
m = 10/65 = m = 2/13
2 x 5 = 10
13 x 5 = 65

Answer:
m<v= 60 degrees
m<x= 100 degrees
Step-by-step explanation:
1) First let's find the measure of angle v. Most of the time if none of the angles are known then it is impossible to find others. However, this specific triangle is an equilateral, which has special rules. We know this is an equilateral because all the sides have the same length. Equilaterals will always have angles with measures of 60 degrees. This is due to the fact that sides and angles are proportionate. Therefore, if all the sides are the same, then the angles must be as well and 180 divided by 3 is 60.
2) Then, we can find the next measurement. This triangle is isosceles. Isosceles triangles have 2 equal sides and angles. The triangle represented above has 2 congruent sides; therefore, the base triangles must also be congruent. So we know that angles Y and W are 40. To find angle X make the expression 180-(40+40). This means that angle x must be 100 degrees.

6 adults & 4 senior citizens have to pay $228 while 13 adults and 7 senior citizens have to pay $459 to visit an exhibition at the Art science Museum . Find the total amount 2 adults & Senior citizen have to pay to visit the exhibition.
Answer: Rs. 69
Step-by-step explanation:
Let the amount that the adults have to pay be Rs. “x” and the amount that the senior citizens have to pay be Rs. “y”.
Step 1:
According to the question, we get
Equation 1:
6x + 4y = 228
Equation 2:
13x + 7y = 459
Step 2:
Then, by multiplying equation 1 by 7 & equation 2 by 4, we get
7 * [6x + 4y = 228]
⇒ 42x + 28y = 1596 …. (iii)
And,
4 * [13x + 7y = 459]
⇒ 52x + 28y = 1836 …. (iv)
Step 3:
Now, Subtracting eq. (iii) from eq. (iv), we get
52x + 28y = 1836
42x + 28y = 1596
(-) (-) (-)
---------------------------
10 x = 240
----------------------------
⇒ x = 240/10 = 24
Substituting the value of x in Eq. (1)
(6*24) + 4y = 228
⇒ y = [228 - 144]/4 = 21
Step 4:
Thus,
The total amount that 2 adults and a senior citizen have to pay to visit the exhibition is,
= 2x + y
= (2*24) + 21 ….. [substituting x= 24 & y = 21]
= Rs. 69

An increase of 20 miles per hour in the average speed of the plane decreases the travel time by 12 minutes. What initial average speed results in this decrease in travel time? (Round your answer to one decimal place.)
The speed of the airplane is the ratio of the distance to the time
The initial average speed of the airplane is approximately 110.8 mph
Reason:
Given parameters are;
The distance between Portland Oregon and Seattle Washington = 145 miles
The decrease in travel time when the speed is increase by 20 mph = minutes
The initial speed of the airplane, v = Required;
Solution;
[tex]t = \dfrac{145}{v}[/tex]
[tex]t - \dfrac{12}{60} = \dfrac{145}{v + 20}[/tex]
Therefore;
[tex]\dfrac{145}{v} - \dfrac{12}{60} = \dfrac{145}{v + 20}[/tex]
Which gives;
[tex]\dfrac{145}{v + 20} - \dfrac{145}{v} + \dfrac{12}{60} = 0[/tex]
Therefore
0.2·v² + 4·v - 2,900 = 0
v ≈ ±110.8 mph
The initial average speed of the airplane, v≈ ± 110.8 mph
