long explanation: these are (x,y) sets {(0,3), (3,0), (0,4), (4,0)} the first choice shows that there are two X solutions if they are equal to 0 (0,3) (0,4) so this cant be a function.

second choice {(0,2), (2,0), (4,6), (6,4)} does not have two X solutions so this is a function
third choice{(2,6), (3,6), (4,6), (2,0)} has two X solutions if x is equal to 2
and the last choice {(6,2), (2,0), (4,6), (6,4)} has two X solutions if x is equal to 6

Final answer:

Set B is the only set that represents a function.

Explanation:

A function is a relation in which each element of the domain is mapped to a single, unique value in the range. In set A, there are two distinct ordered pairs with the same first element, making it not a function. In set B, each member of the domain occurs in just one ordered pair, making it a function. Therefore, set B is the only set that represents a function.

A movie made $297.2 million in 22 weeks. How much did the movie make on average each week?

Answers

Final answer:

The movie made an average of $13.509 million each week.

Explanation:

To find the average amount of money the movie made each week, we need to divide the total amount made by the number of weeks. In this case, the movie made $297.2 million in 22 weeks. To find the average, we divide $297.2 million by 22, which gives us an average of $13.509 million per week.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total number of boys in the class be = A

Let the total number of girls in the class be = B

Now , the percentage of students in the class that are boys = 40 %

So , ( 40/100 ) of the students are boys

A = 40/100

A = 0.4

Now , the remaining students in the class are girls

So , 100 - 40 = 60

The percentage of students in the class that are girls = 60 %

So , ( 60/100 ) of the students are girls

B = 60/100

B = 0.6

Hence , The percentage of students that are girls in Mr.Klein's class is 60 % and the decimal value is 0.6

How do I solve this?

Answers

First, you isolate the absolute value.

4 + 8|2b| = 84

8|2b| = 80

|2b| = 10

Now to solve the absolute value part, set what is inside the absolute value equal to 10 and set it equal to -10 and solve both equations.

2b = 10   or   2b = -10

b = 5   or b = -5

Team Tool Bella canoed 15 3/4 miles in 5 1/4 hours. What was their average speed in miles per hour

Answers

Thee miles per hour

we know that

To find the average speed divide the total distance by the time

In this problem we have

[tex]total\ distance=15\frac{3}{4}\ miles[/tex]

[tex]time=5\frac{1}{4}\ hours[/tex]

Convert mixed numbers to an improper fractions

[tex]total\ distance=15\frac{3}{4}\ miles=\frac{15*4+3}{4} =\frac{63}{4}\ miles[/tex]

[tex]time=5\frac{1}{4}\ hours=\frac{5*4+1}{4} =\frac{21}{4}\ hours[/tex]

Divide the total distance by the time

[tex]\frac{(63/4)}{(21/4)} =\frac{63}{21} =3\frac{miles}{hours}[/tex]

therefore

the answer is

the average speed is  [tex]3\frac{miles}{hours}[/tex]

Omar owns a sandwich shop, and his best selling sandwich is the BLT. When making BLT sandwiches, it takes 3/4 of a pound of bacon to make 4 sandwhiches. he uses 1 1/20 pounds of bacon for every 2 tomatoes used and 5 tomatoes for every full head of lettuce used. If Omar is making enough BLT sandwiches to use 2 full heads of lettuce, then he is going to use blank pounds of bacon and will make a total of blank blt sandwiches.

Answers

Answer:

He is going to use 21/4 pounds of bacon.

He will make a total of 28 BLT sandwiches.

Step-by-step explanation:

It is given that:

for every full head of lettuce used the number of tomatoes used are: 5

This means that when he used 2 full heads of lettuce then the number of tomatoes which are used are: 10

( since for 1 head of lettuce --- 5 tomatoes are used.

and for 2 head lettuce---- 5×2=10 tomatoes are used )

Now, it is given that for every two tomatoes used 1 1/20 pounds of bacon is used.

i.e. for every 2 tomatoes --  21/20 pounds of  bacon is used.

Hence, for 1 tomato---   (21/20)×(1/2) pound of bacon is used.

i.e. for 1 tomato ---- 21/40 pound of bacon is used.

Hence, for 10 tomatoes ---(21/40)1×10 pounds of bacon is used.

i.e. for 10 tomatoes ---- 21/4 pounds of bacon is used.

Now, it is given that:

with the help of 3/4 pounds of bacon 4 sandwiches are made.

Hence, with the help of 1 pound of bacon  16/3 sandwiches will be made.

Hence, with the help of 21/4 pounds  of bacon  (16/3)×(21/4) sandwiches could be made.

i.e. with the help of 21/4 pounds of bacon 28 sandwiches could be made.

Final answer:

To calculate the amount of bacon Omar will use to make BLT sandwiches and the total number of sandwiches, we follow the given conversion factors. We set up proportions to find the amount of bacon used for the total sandwiches and the two full heads of lettuce. The total number of sandwiches is found by dividing the number of tomatoes by 5.

Explanation:

To calculate the amount of bacon Omar will use to make BLT sandwiches and the total number of sandwiches, we need to follow the given conversion factors. 1. For every 4 sandwiches, 3/4 of a pound of bacon is used. So, we can set up a proportion: 3/4 pound / 4 sandwiches = x pound / total sandwiches. Solving for x will give us the amount of bacon used for the total sandwiches. 2. For every 2 tomatoes, 1 1/20 pounds of bacon is used. Since Omar is using 5 tomatoes for two full heads of lettuce, we can set up another proportion: 1 1/20 pounds / 2 tomatoes = x pound / 5 tomatoes. Solving for x will give us the amount of bacon used for the two full heads of lettuce. To find the total amount of bacon used, we add the amount used in the sandwiches to the amount used for the lettuce. Finally, the total number of sandwiches can be found by dividing the number of tomatoes by 5.

Erase 3/5 of the shape part below. How much of the original figure will be shaded?

Okie doke. So, to find what 3/5 of the shape would be above, we should do 2/3 * 3/5. When you multiply straight across, you get 6/15 or 2/5 in simplest form. 2/5 of the original figure will be shaded after you erase 3/5 of the shaded part. The answer is 2/5.

The amount of the original figure shaded is 4/15

How to find how much left

the sum of two numbers is 70 and their difference is 24.Find the two numbers

Answers

The two answers are 23 and 47. You would subtract 24 from 70 then divide by 2 which would equal 23 then add the 24 back to it which is 47. 23 plus 47 equals 70.

The two numbers whose sum is 70 and has a difference of 24 is 23 and 47

Let

x = smaller number

y = Larger number

y + x = 70 (1)

y - x = 24 (2)

subtract (2) from (1) be to eliminate y

x - (-x) = 70 - 24

x + x = 46

2x = 46

x = 46 / 2

x = 23

substitute x = 23 into (1)

y + x = 70

y + 23 = 70

y = 70 - 23

y = 47

Therefore, two numbers whose sum is 70 and has a difference of 24 is 23 and 47

NO. You cannot subtract 3x from 6, since they are NOT like terms. 
You can think of it as the 6 does not have an x term, but in 3x, there is an x term. 
Answer:  When "x = 1" ;  "2(6-3x) + x"  DOES EQUAL "2(3x) + x" .

the graph shows the height of 10 sunflower grown in pjs garden

Answers

i think it is 1/2. (just filling the 20 characters now)

Answer:

B. [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

We have been given a graph that shows the height of the 10 sunflowers grown in PJ's garden. We are asked to find the probability that the 11th flower will be at least 60 inches.  

[tex]\text{Probability}=\frac{\text{Total number of favorable outcomes}}{\text{total number of possible outcomes}}[/tex]

From the given experiment we can see that there are 5 sunflowers with height more than or equal to 60 inches, so total number of favorable outcomes is 5.

Since there are total 10 sunflowers, so total number of possible outcomes is 10. Upon substituting our given values in probability formula we will get,

[tex]P(\text{The 11th plant will be at least 60 inches})=\frac{5}{10}[/tex]

[tex]P(\text{The 11th plant will be at least 60 inches})=\frac{1}{2}[/tex]

Therefore, the probability that 11th plant will be at least 60 inches is [tex]\frac{1}{2}[/tex] and option B is the correct choice.
