Answer:
[tex]y = \frac{1}{2}x +4[/tex]
Step-by-step explanation:
Given:
[tex]R = (0,0)[/tex]
[tex]S= (8,4)[/tex]
[tex]T = (-2,3)[/tex]
First, we have that the line is parallel to RS.
This means that the line has the same slope as RS and the slope of RS is calculated as follows:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{4-0}{8-0}[/tex]
[tex]m = \frac{4}{8}[/tex]
[tex]m = \frac{1}{2}[/tex]
So, the line has a slope of [tex]m = \frac{1}{2}[/tex]
Next, we have that the line passes through [tex]T = (-2,3)[/tex].
The equation of the line is then calculated using the following formula
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 3 = \frac{1}{2}(x - (-2))[/tex]
[tex]y - 3 = \frac{1}{2}(x +2)[/tex]
Open bracket
[tex]y - 3 = \frac{1}{2}x +1[/tex]
Make y the subject
[tex]y = \frac{1}{2}x +1+3[/tex]
[tex]y = \frac{1}{2}x +4[/tex]
Events A and B are independent. The probability of A given B has occurred is 0.43, and the probability of B given A has occurred is 0.35.
What is the probability, to the nearest hundredth, that A and B occur?
Answer:
0.43* 0.35 = 0.1505 or 0.15 after rounding
Step-by-step explanation:
Based on the probabilities of A and B occurring with conditions, the probability of A and B occurring is 0.15.
What is the probability that both A and B occur?This can be found by the formula:
= Probability that A occurs if B occurs x Probability of B occurring if A occurs
Solving gives:
= 0.43 x 0.35
= 0.15
In conclusion, the probability is 0.15.

The volume of a cube is given by s9 and the total surface area of a cube is given by 632, where s is the side length of the cube.
If the side length of a cube is 5 inches, the volume of the cube is [ ]
cubic inches and its total surface area is[ ]
square inches

Answer:
Surface area of a cube = side * side * 6
632 = side * side * 6
side^2 = 632/6
side^2 = 105.3333333333
side = 10.2632028789

(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.
(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.
What is velocity?Velocity is the rate of change of displacement with time. The velocity of the cars depends on displacement and time of motion.
First velocity of the car at the 0.25 meter markThe first velocity is calculated as follows;
v1 = 0.25 m / t1
let t₁ = 2 s
v₁ = 0.25/2
v₁ = 0.125 m/s
Second velocity of the car at the 0.5 meter markv2 = 0.25 m / (t2 – t1)
let t₂ = 3 s
v₂ = 0.25(3 - 2)
v₂ = 0.25 m/s

Kareem cannot decide which of two washing machines to buy. The selling price of each is $480. The first is marked down by 30%. The second is marked down by 20% with an additional 10% off. Find the sale price of each washing machine. Use pencil and paper. Explain why Kareem should buy the first washing machine rather than the second if the machines are the same except for the selling price.
Answer:
1. $336
2.$345.6
Step-by-step explanation:
First off the first machine is cheaper because of the 30% off of the total price rather than 20 off the price then another 10 percent off that price.

PROBLEM: Juan hires an electrician. Juan pays a one-time fee of $30. Juan also pays $45 for each hour the electrician works. A. Write a function that can be used to find the total charge, c, Juan will pay when the electrician works, h, hours. Y=mx+b B. How much will Juan pay if it takes the electrician 6 1/2 hours to complete the job? (Vou should have 9 answers in question 2
Answer:
A: C=45h+30
B: C=$322.50
Step-by-step explanation:
A: We'll start with the equation for the total charge. Juan is saying he will pay a one time fee of $30, meaning there is 30 dollars added to what ever the hourly wage is. This can be represented by the +30. Now if "h" represents the variable for which the hourly wage will be calculated, and he pays $45 dollars per hour this will be represented as 45h. As an example if I pay you 2 dollars per hour using the same variable "h", this would be represented as 2h. So if you worked for two hours you would get 4 dollars, this is proven by the fact the 2(2) (remeber im replacing the "h" with the hours you worked) obviously 2 times 2 is 4 proving my point. This information will give you the equation you see above.
B: Onto solving for how much Juan will pay. Now you say youre supposed to have 9 answer but this can't be true. All you need to do is plug the hours given into "h" and solve the equation. It should look something like:
C=45h+30
C=45(6.5)+30
Im using a decimal because it should be clear 1/2=0.5
C= 292.5+30
45x6.5 always go with PEMDAS, we are multiplying first. Then add 292.5 plus 30
This results in the answer of:
C=$322.50
From his house, Shane could drive due north to get to his parents' house or he could drive due east to get to his grandparents' house. It is 8 miles from Shane's house to his parents' house and a straight-line distance of 17 miles from his parents' house to his grandparents' house. How far is Shane from his grandparents' house?
Answer:
15 miles
Step-by-step explanation:
It is given that,
Shane could drive due north to get to his parents' house or he could drive due east to get to his grandparents' house.
It is 8 miles from Shane's house to his parents' house and a straight-line distance of 17 miles from his parents' house to his grandparents' house.
It can be calculated by considering a right angled triangle. Using pythagoras theorem, we can find the distance between Shane from his grandparents' house. Let it is d.
[tex]d^2=\sqrt{17^2-8^2} \\\\=15\ \text{miles}[/tex]
Hence, Shane is 15 miles from his grandparents' house.

1080 m^2 Don't submit m^2 in your answer.
Step-by-step explanation:
Givens
The catch is to find h
To do that, use a^2 + b^2 = c^2
a b and c are in the same 1/2 triangle.
a = 48/2 = 24 m
b = h = ?
c = 51 meters
Solution
a^2 + b^2 = 51^2 Substitute for b^2 = h^2
24^2 + h^2 = 51^2 Expand 24^2 and 51^2
576 + h^2 = 2601 Subtract 576 from both sides
h^2 = 2601 - 576
h^2 = 2025 Take the square root of both sides
h = 45
Area
Area = 1/2 b * h
Area = 1/2 48 * 45
Area = 1080
Remark
Notice that to find h you only use 1/2 of 48 because that is the base of the right triangle.
To find the area, you need to use all of 48 because 48 is the full length of the base.

Identify the Y intercept of the the equation 5x+8y =120
O A. (0,24)
O B. (15,0)
O C. (0,15)
O D. (24,0)
Answer:
(0,15)
Step-by-step explanation:
The Y-intercept is when X=0, so plug in x=0 into the given equation. 5(0)+8y=120. Now solve for Y. 8y=120, y=15. So When x=0, y=15: this is the coordinate (0,15).
y = -x + 5

In order to construct the perpendicular bisector of AB, which statement describes the compass settings and the number of arc intersections needed? A less than half the length of AB : 1 B В. less than half the length of AB : 2 more than half the length of AB : 1 O D more than half the length of AB : 2
Answer:
Answer:
D. More than half the length of AB ; 2 intersections needed
Step-by-step explanation:
Bisection implies dividing a given segment or angle into two equal halves.
To bisect AB, open the radius of the compass more than half the length of AB. With center A, describe an arc at the upper region of AB and below AB. Now, using B as the center, draw a second arc upward and downward to intersect the initial arcs at a point. Join the two points of intersection with a line passing through AB. Thus, AB has been bisected.
