If R= (-1, 0, 1, 2, 4, 5) and S = (4, 5, 6) Find R (upside down U) S.
Answers: A) (-1, 0, 1, 4, 5). B) (4,5). C) () D) (-1, 0, 1, 2, 4, 5, 6)
Answer:
Option B is correct.
Step-by-step explanation:
Given
R = {-1, 0, 1, 2, 4, 5}
S = {4, 5, 6}
To determine
R ∩ S = ?
The intersection of two given sets R and S is the largest set which consists of all the elements that are common to both sets.
Thus, we conclude that:
R = {-1, 0, 1, 2, 4, 5}
S = {4, 5, 6}
The intersection of two given sets R and S:
R ∩ S = {4, 5}
Hence, option B is correct.
Convert the following equation to slope-intercept form
3x-2y=7
Step-by-step explanation:
Slope-intercept form: y = mx + c.
3x - 2y = 7
=> 2y = 3x - 7
=> y = 1.5x - 3.5.
A trail is
of 9/10 of a mile long. Abdul hiked 2/5
of the length of the trail. Which steps could be used to determine how far he hiked, in simplest terms? Check all that apply.
-Add 9/10 to 2/5
-Find the product as follows: 9/10 x 2/5=11/50
-Find the product as follows: 9/10 x 2/5 = 18/50
-Find a common factor for the numerator and denominator.
-Simplify the product as 9/25
mile.
Answer:
The third and fifth ones
Step-by-step explanation:
To find the answer to this, you have to multiply 9/10 and 2/5 to get 18/50, making the third one true. The next thing you would do is simplify 18/50 to get 9/25, making the fifth choice true.
Your total cost with tax is $29.51, including 7% sales tax. What is the price without the tax?
Step-by-step explanation:
Make an equation first.
29.51=1.07 (x)
The 29.51 is after the 7% sale tax, so we are trying to figure out the original price.
After you make the equation, you solve the 1 step equation.
Divide both sides by 1.07 to get the answer.
27.57944=x
So you woyld want to round this answer to get $27.58

Two faulty tennis ball machines start to shoot balls from opposite sides of a 25 meter by 10 meter tennis court. The green ball machine shoots green balls that stop on the court 5 meters to 20 meters from the green machine's side. The yellow ball machine shoots yellow balls that stop on the court 2 meters to 16 meters from the yellow machine's side. Find the area of the tennis court that has balls of either color on it.
Answer:
180 m²
Step-by-step explanation:
The tennis court has a length of 25 meters and a width of 10 meters. The faulty tennis ball machines are placed at both ends of the court length.
The green ball machine has a range of 5 meters to 20 meters from the green machine's side while the yellow ball machine has a range of 2 meters to 16 meters from the yellow machine's.
Therefore the area of the tennis court with balls on it, has a range of 2 meters from the yellow machine and 5 meters from the green ball machine. Hence:
length of court with balls = 25 m - (5 m + 2 m) = 25 m - 7 m = 18 m
width of court = 10 m
Therefore, the area of the tennis court that has balls of either color on it = length of court with balls * width of court with balls = 18 m * 10 m = 180 m²

A weather forecaster reported that the total amount of rainfall for the month was 0.95 inch. He also reported that this amount was 0.35 inch below the average amount of rainfall for the same month during the last ten years. The forecaster summarized his findings in this table. What was the average amount of rainfall, in inches, for this month during the last ten years?
Answer:
1.3 in
Step-by-step explanation:
x = average amt of rainfall in the last 10 years
0.95 = x - 0.35
0.95 + 0.35 = x
1.3 = x

there are 30 6th graders, 40 seventh graders, and 20 eighth graders marching in a band. How many degrees in a circle graph are needed to represent band members in each grade relative to the entire band
Answer:
324 degrees
Step-by-step explanation: A circle has 360 degrees. In the question, they are 90 quantities. So that means we need 90% of the circle graph.
So first let divide 90 by 100 which gives us 0.9.
Now let multiply 0.9 times 360 which gives us 324.
Tariq has earned $54 for cutting the grass of three houses.
Part A: If he continues to earn money at this rate, how much will he make after cutting all 11 lawns on his street?
Part B: How many lawns would he need to cut if he wanted to earn enough money to buy an Xbox One that costs $324?
Answer:
Part A: $198
Part B: 18 lawns
Step-by-step explanation:
Part A:
Find out how much he earns for cutting the grass of one house.
3 houses = 54
1 house = 54 ÷ 3 = 18
11 houses = 18 x 11 = 198
(Final answer)
Part B:
Since you know how much you earn for cutting the grass of one house, take the amount of money needed divided by how much you earn for cutting grass per house.
324 ÷ 18 = 18
(Final answer)
