Answer:
y = -2/3x + 8
Step-by-step explanation:
Format: y = mx + b
m = slope (rise over run) - 2/3 The graph is negative so the slope is also negative.
b = y - intercept (8)

A person is standing 215 feet above the ocean
watching a ship come in. Initially the angle of elevation
from the boat to the person is 31 degrees. After
traveling towards the person for a few minutes, then
angle is 48 degrees. How far did the boat travel
between the two points? Round to the nearest foot.
Answer:
Step-by-step explanation: I don’t know I just want my extra points
Answer: 164 ft
Step-by-step explanation:
tan 48=215/x
-> x.tan48=215
->x =215/tan 48
->x = 193.6
tan 31=215/y
-> y.tan31 = 215
-> y= 215/ tan 31
-> y= 357.82
BC= y-x
= 357.82-193.6
= 164.22 = 164 ft
Mrs. Williamson had 18 students in her homeroom at the beginning of the school year and 24 students at the end of the year. What was the approximate percent increase in the number of students in Mrs. Williamson’s homeroom?
25%
33%
57%
75%
Answer:
25%
Step-by-step explanation:
An easy way to figure this out is just by dividing the initial amount of students (18) by the current amount of students (24), and then subtracting 1.
So, 18/24 = 0.75 (aka 75%), and 1 - 0.75 = 0.25 (aka 25%)

Step-by-step explanation:
Do cross multiplication.
In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Olivia sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below. 144 visitors purchased no costume. 182 visitors purchased exactly one costume. 9 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase no more than one costume as a decimal to the nearest hundredth.
Answer:
There is a 54.328% probability that the next person will purchase no more than one costume.
Step-by-step explanation:
Since in a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance, and Olivia sets up a website where players can buy and sell these costumes online, and information about the number of people who visited. the website and the number of costumes purchased in a single day states that 144 visitors purchased no costume, 182 visitors purchased exactly one costume, and 9 visitors purchased more than one costume, to determine, based on these results, the probability that the next person will purchase no more than one costume as a decimal to the nearest hundredth, the following calculation must be performed:
144 + 182 + 9 = 335
335 = 100
182 = X
182 x 100/335 = X
18,200 / 335 = X
54,328 = X
Therefore, there is a 54.328% probability that the next person will purchase no more than one costume.

1. Lilly has two cousins. One of the cousins is 7 years older than Lilly. The other cousin is 3 years younger than Lilly. The product of Lilly’s cousins' ages is 24. How old is Lilly?
2. Jackie is building a rectangular football field that has an area of 6000 square yards. The football field must be 40 yards longer than its width. Determine the width of the football field, in yards.
3. James is reading a book and noticed the page numbers are consecutive integers whose product is 1640. What is the value of the larger page number?
Answer: a. 5 years
b. 60 yards
c. 41
Step-by-step explanation:
1. Let Lily's age be x.
One of the cousins is 7 years older than Lilly. The age will be = x + 7
The other cousin is 3 years younger than Lilly. The age will be = x - 3
Therefore, (x + 7)(x - 3) = 24
x² - 3x + 7x - 21 = 24
x² + 4x - 21 - 24 = 0
x² + 4x - 45 = 0
x² + 9x - 5x - 45 = 0
(x² + 9x) - (5x - 45) = 0
x(x + 9) - 5(x + 9) = 0
(x - 5)(x + 9) = 0
(x - 5) = 0
x = 0 + 5
x = 5
Therefore, Lily is 5 years
2. Let the width be represented by x
Therefore, length will be x + 40.
Area = length × width
6000 = x(x + 40)
x² + 40x = 6000
x² + 40x - 6000 = 0
x² + 100x - 60x - 6000 = 0
x(x + 100) - 60(x + 100) = 0
(x - 60)(x + 100) = 0
x - 60 = 0
x = 0 + 60 = 60
Therefore, the width is 60 yards
3. Let the consecutive numbers be x and x+1.
Therefore, x(x + 1) = 1640
x² + x = 1640
x² + x - 1640 = 0
x² + 41x - 40x - 1640 = 0
x(x + 41) - 40(x + 41) = 0
(x - 40) = 0
x = 0 + 40
x = 40
Larger number = x + 1 = 40 + 1 = 41

Solve: Four more than a number is more than 13
Inequality :
Solution :
Answer:
x + 4 > 13
x > 9
Step-by-step explanation:
In this equation, the value of the "number" is unknown, so I used a variable (x) to represent the unknown value.
FOUR more than x would mean addition.
x + 4.
According to this word problem, four more than x is larger than thirteen, so a greater than symbol was used.
Like this,
x + 4 > 13.
We can find the solution to 'x' by subtracting 4 from 13.
Like this,
13 - 4 = 9
Therefore, the solution is x > 9
And, the inequality is x + 4 > 13.
The length of a living room is 12ft and it's width is 10 1/2 ft. The length of the living room is being expanded by X feet? Choose an expression to represent the new area of the living room in square feet and the expanded fotm of the expression? Select all that apply
Answer:
C. 10.5(12 + x) square feet
E. (126 + 10.5x) square feet
Step-by-step explanation:
A. 10.5(12x) square feet
B. (10.5 + 12 + x) square feet
C. 10.5(12 + x) square feet
D. 126x square feet
E. (126 + 10.5x) square feet
F. (22.5 + x) square feet
length of a living room = 12ft
width = 10 1/2 ft
The length of the living room is being expanded by X feet
New length of a living room = 12ft + x feet
new area of the living room = length × width
= 12ft + x feet × 10 1/2 ft
= (12 + x) 10 1/2
Note: 10 1/2 is equivalent to 10.5
= (12 + x) 10.5
= (126 + 10.5x) square feet
Options that applies
C. 10.5(12 + x) square feet
E. (126 + 10.5x) square feet

Without properly working spark plugs, a vehicle will not run. For a specific vehicle, the spark plugs are supposed to have a gap between 3.9mm and 4.3mm. Any spark plugs with gaps larger or smaller than this will fail inspection and be discarded. At the factory, the machine that sets the gap follows a normal distribution with a mean of 4.1mm and standard deviation of 0.075mm. What is the probability that a randomly selected spark plug passes inspection
Answer:
The probability that the spark plugs are supposed to have a gap between 3.9mm and 4.3mm.
P(3.9≤X≤4.3) = 0.9922
Step-by-step explanation:
Step(i):-
Given that the mean of the Normal distribution = 4.1mm
Given that the standard deviation of the Normal distribution = 0.0075mm
Let 'X' be the random variable in a normal distribution
Given that X₁ = 3.9mm
[tex]Z_{1} = \frac{X_{1} -mean}{S.D}[/tex]
[tex]Z_{1} = \frac{3.9 -4.1}{0.075} = -2.666[/tex]
Given that X₂ = 4.3mm
[tex]Z_{2} = \frac{X_{2} -mean}{S.D}[/tex]
[tex]Z_{1} = \frac{4.3 -4.1}{0.075} = 2.666[/tex]
Step(ii):-
The probability that the spark plugs are supposed to have a gap between 3.9mm and 4.3mm.
P(3.9≤X≤4.3) = P(-2.666≤Z≤2.666)
= P(Z≤2.666)-P(Z≤-2.666)
= 0.5 +A(2.666) - (0.5-A(2.666)
= 2 × A(2.666)
= 2×0.4961
= 0.9922
Final answer:-
The probability that the spark plugs are supposed to have a gap between 3.9mm and 4.3mm.
P(3.9≤X≤4.3) = 0.9922

find the missing measurement
9514 1404 393
Answer:
4.2 km
Step-by-step explanation:
The altitude of the triangle can be found using the triangle area formula:
A = 1/2bh
22.7 km² = 1/2(10.8 km)h
h = (22.7 km²)/(5.4 km) ≈ 4.2037... km
The missing measurement is about 4.2 km.

The given expression is:
[tex]\dfrac{-2}{3}\times \dfrac{5}{7}\times \dfrac{-9}{16}\times \dfrac{14}{25}[/tex]
To find:
The value of the given expression.
Solution:
We have,
[tex]\dfrac{-2}{3}\times \dfrac{5}{7}\times \dfrac{-9}{16}\times \dfrac{14}{25}[/tex]
It can be written as:
[tex]=\dfrac{-2}{3}\times \dfrac{5}{7}\times \dfrac{-3\times 3}{2\times 2\times 2\times 2}\times \dfrac{2\times 7}{5\times 5}[/tex]
[tex]=\dfrac{-2\times 5\times (-3)\times 3\times 2\times 7}{3\times 7\times 2\times 2\times 2\times 2\times 5\times 5}[/tex]
Cancel out the common factors.
[tex]=\dfrac{-(-3)}{2\times 2\times 5}[/tex]
[tex]=\dfrac{3}{20}[/tex]
Therefore, the value of given expression is [tex]\dfrac{3}{20}[/tex].
