Consider U = {x|x is a real number}. A = {x|x ∈ U and x + 2 > 10} B = {x|x ∈ U and 2x > 10} Which pair of statements is correct? 5 ∉ A; 5 ∈ B 6 ∈ A; 6 ∉ B 8 ∉ A; 8 ∈ B 9 ∈ A; 9 ∉ B
8 is not an element of set A since all the elements must be greater than 8. 8 ∉ A is correct.
Sets and valuesGiven the following set of values
U = {x|x is a real number}
A = {x|x ∈ U and x + 2 > 10}
B = {x|x ∈ U and 2x > 10}
The equivalent elements of the sets are:
U = {real numbers}
A = {x > 8}
B = {x > 5}
From the set above, we can see that 8 is not an element of set A since all the elements must be greater than 8.

Rhianna is baking a cake and some cookies for a party. She used cups of flour for the cake. For each tray of cookies, she needs cups of flour. She decides to use at least 15 cups of flour for the cake and the cookies.
Assuming she can make fractional trays of cookies, how many trays, x, can she make? Select the inequality that includes the minimum number of trays of cookies Rhianna can make.
Answer:
x > 15
Step-by-step explanation:
At least means that x will be greater than 15 so it is x > 15.

Answer:
Tennessee
Step-by-step explanation:
First, let's find out how much tax he paid...
$695.49-$649.99=$45.50
We can use this to set up an equation...
x%(649.99)=45.50
We can convert x% to x/100 since any percentage is just that number over one hundred...
[tex]\frac{x}{100}*649.99=45.50\\\\\frac{649.99x}{100}=45.50[/tex]
Multiply 100 to both sides
[tex]649.99x=4550[/tex]
Divide both sides by 649.99
[tex]x$\approx$6.92[/tex]
This is closest to 7 (our answers is not exact since you can only have two decimal places in money), therefore he lives in D. Tennessee

One week, Steph worked 20 hours, Marco
worked 12 hours, and Destiny worked 32 hours.
How much did the owner, Layla, pay herself?
Answer: 9
Step-by-step explanation:
Add 20, 12, and 32 together then divide by 7 because it says "One week" and a week is 7 days. So, it should be like 20 +12 + 32= 64
64 / (divided by) 7 = 9
The number of daily work hours, if in One week, Steph worked 20 hours, Marco worked 12 hours, and Destiny worked 32 hours, is 9.1 hours.
What is division?It is the basic arithmetic operation, in which you are separating the number into some parts.
Given:
One week, Steph worked 20 hours, Marco worked 12 hours, and Destiny worked 32 hours,
Calculate the total time of work as shown below,
The total time = 20 + 12 + 32
The total time = 64 hours in a week
Calculate the daily work time as shown below,
Daily work time = 64 / 7
(1 week = 7 days)
Daily work time = 9.1 hours

3- 7.2 kg of sugar cost R51.84.
4- It will use 4 liters of oil to travel a distance of 80km.
5- Peter can paint 8 square meters with 1 liter of paint.
Calculus
To answer the questions made, the following calculations must be made:
1. If 15 apricots cost R5.60, how many apricots will cost R10.08?
5.60 = 1510.08 = X10.08 x 15 / 5.60 = X151.2 / 5.6 = X27 = XTherefore, 27 apricots will cost R10.08.2. How much will it cost for 1kg of polony if 0.35 kg of polony costs R25.10?
0.35 = 25.101 = X25.10 / 0.35 = X71.71 = XTherefore, 1 kg of polony will cost R71.71.3. If 12.5 kg of sugar cost R90, how much will 7.2 kg of the sugar cost?
12.5 = 907.2 = X7.2 x 90 / 12.5 = X648 / 12.5 = X51.84 = XTherefore, 7.2 kg of sugar cost R51.84.4. A scooter uses 6.5ℓ petrol to travel a distance of 130 km. How much petrol will it use to travel a distance of 80km?
130 = 6.580 = X80 x 6.5 / 130 = X520 / 130 = X4 = XTherefore, it will use 4 liters of oil to travel a distance of 80km.5. Peter used 5ℓ of paint to paint a wall that is 8m long and 5m high. How many square meters can Peter paint with 1ℓ of paint?
8 x 5 = 4040 / 5 = 8Therefore, Peter can paint 8 square meters with 1 liter of paint.Learn more about calculus in https://brainly.com/question/26453068
The actual distance between town A and twon b is 64 question # 10
Answer:
8 cm; from the table
Step-by-step explanation:
The equation gives the ground distance in terms of the map distance, so would have to be solved for x to be used to find map distance.
The graph is not shown.
The table appears correct, and includes the value 32 km for a map distance of 4 cm. The ground distance of interest is 64 km, which is twice that table value. That means the map distance will be twice the corresponding table value: 2×4 cm = 8 cm.
The distance from Town A to Town B is represented on the map by 8 cm.

Grandma baked 1.5 times as many pancakes as waffles. After she baked 45 more waffles, and her grandchildren eat 12 pancakes, there were 17 more waffles than pancakes. How many waffles were there initially
Answer:
(x + 45) - (1.5x - 12) = 17
Step-by-step explanation:
The number of waffles there were initially is; 80 waffles
Simultaneous equationsLet the number of pancakes be x.
Let the number of waffles be y
Hence, after she baked 45 more waffles, and her grandchildren eat 12 pancakes, what she has is;
y +45 waffles and x-12 pancakes.There were 17 more waffles than pancakes.
y+45 = x-12 +17.......equation (1)And initially, x = 1.5y
Hence, to determine y, we must substitute x = 1.5y into equation (1)
Therefore, we have;
y+ 45 = 1.5y -12+170.5y = 40y = 40/0.5y = 80 waffles.Read more on simultaneous equations;
