A graph represents a function when no vertical line will intersect the graph in more than one point.

Answer:

D) m<1 = 50 m<7 = 130

Step-by-step explanation:

Lets set up the equation!

We know m<4 is 4x-30 and the m<5 is 2x + 50 due to alternate interior angles they are congruent so we can forge an equation, all we do is set them equal to each other!

4x-30 = 2x+50

Add 30 to both sides

4x = 2x +80

Subtract 2x from both sides.

2x = 80

Divide both sides by 2

x = 40

Now that we know x we can just plug it into the expression of m<4 to find m<1

4x-30

4(40)-30

80 - 30

50

m<4 = 50

Because m<1 and m<4 are vertical angles they are congruent!

m<1 = 50

We also know m<4 and m<5 are congruent so m<5 = 50 as well.

Because <7 is supplementary to <5 we know that the sum of both angles amount to 180.

x represents m<7

50 + x = 180

Now we solve by subtraction 50 from both sides

x = 130

m<7 = 130

Answer:

108:72

Step-by-step explanation:

Answer:

The missing value in the ratio that will appear next is: 108 and the ratio is 108:72

Step-by-step explanation:

The pattern of equivalent ratios is given in the picture.

The ratios are equivalent which means that the simplest form of ratio will be same for all ratios in the pattern.

So,

[tex]\frac{18}{12} = \frac{36}{24} = \frac{54}{36} = \frac{72}{48} = \frac{90}{60} = \frac{3}{2}[/tex]

This means that the simplest form of ratio for upcoming in the pattern will be 3/2

Let x be the missing value in ratio

Then

[tex]\frac{x}{72} = \frac{3}{2} \\x = \frac{3}{2} * 72\\x = 108[/tex]

Hence,

The missing value in the ratio that will appear next is: 108 and the ratio is 108:72

The recursive formula will be g(n) = g(n-1) + 5

"A recursive formula refers to a formula that defines each term of a sequence using the preceding term(s). The recursive formulas define the following parameters:

The first term of the sequence.

The pattern rule to get any term from its previous term.

Recursive Formula for Arithmetic Sequence

The recursive formula to find the nth term of an arithmetic sequence is:

an = an-1 + d for n ≥ 2

where

an is the nth term of a A.P.

d is the common difference."

Given,

[tex]g(n) = 1 + 5(n-1)[/tex]

Let the remaining term be x

Now,

[tex]g(n) = g(n-1) + x 1 + 5(n-1) = 1 + 5(n - 1 - 1) + x\\\\ 1 + 5n - 5 = 1 + 5n - 10 + x \\\\x = 5[/tex]

So, [tex]g(n) = g(n-1) + 5[/tex]

And, [tex]g(1) = 1 + 5(1 - 1) + 5[/tex]

[tex]g(1) = 6[/tex]

Hence, [tex]g(1) = 6[/tex] and [tex]g(n) = g(n-1) + 5[/tex]

Answer:

10 liters

Step-by-step explanation:

let sugar in  x liters of 60 % sugar syrup be equivalent to sugar in 40 liters of 45 % sugar syrup.

x×60 %=40×45%

60x=40×45=1800

x=1800/60=30

40-30=10

so 10 liters of 60 % sugar syrup be replaced with 10 liters of distilled water to make 40 liters of 45 % sugar syrup.

Answer:  The baker needs to pour off 10 liters of the solution and replace it with 10 liters of distilled water.

.6(40) = 24.  .45(40) = 18  24-18 = 6   6 = .6(10)  10 liters must be substituted.

Step-by-step explanation:

The original 60% solution contains 24 L syrup and 16 L water.

A 45% solution must contain 18 L syrup and 22 L water.

The difference in syrup is 6 L.  10 L of the 60% solution contains 6 L syrup.

After pouring off  10 L, the remaining  30 L will contain 18 L syrup and 12 L water.  

By adding 10 L water, the resulting solution is 18 L syrup and 22 L water.

18/40 = .45 which is the desired 45% syrup.

1. More time for studying

2. Possibly change your study habits

3. Make sure that you are learning with the technique that works best for you

Step-by-step explanation:

1. Allow yourself more time to study. If this is a specific subject that you feel that you are struggling in, allow yourself more time in a day to study your notes and prep for classwork, tests, etc. in comparison to your other classes.

2. If you feel that your current studying method(s) is working for you, great! If not, there are so many other methods that may work better for you. There's tons of videos on the internet regarding ways to study, there's internet articles explaining ways, and so many other resources! You may learn new ways to take notes, find the perfect balance of studying and taking breaks, and possibly even new memorization techniques! Just find out what works best for you!

3. Ask yourself what kind of learning method you prefer. If you prefer working in groups, maybe meet up with some friends for a group study session in which you guys can discuss ideas and questions. If you can't meet in person, try a zoom call! If you prefer learning with visual methods, maybe find some videos on the topic with visuals to demonstrate! Try to study with your preferred method of learning as often as you can!

If you have any other questions, just let me know! I'm happy to help and hope these tips help as well! :)

44 wins

Step-by-step explanation:

47+39+x/100*70

A baseball team has a record of 47 wins and 39 losses, then they have to win 44 games in a row so that their winning percentage will be above 70%. Hence, option E is correct.

The Latin term "per centum," which signifies "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentage are fractions. To put it another way, it's the relationship here between component and a whole, in which the value of the whole is always assumed to be 100. A specific portion or amount in each hundred is referred to as the percentage. The fraction is denoted by the sign "%," and its denominator is 100.

Finding the proportion of a whole in units of 100 is the goal of percentage calculations. There are two methods to calculate a percentage:

Change in y over change in x

Answer:

The zeroes of the function are: 3 and 4

Step-by-step explanation:

Zeroes of a function are the values on which the function produces zero output. To find the zeroes of a function, the function is put equal zero and the values of the variable are found using the equation. The values of x are the zeroes of the function.

Given function is:

[tex]f(x) = (x-3)(2x-8)[/tex]

Putting the function equal to zero

[tex]f(x) = 0\\(x -3)(2x -8) = 0\\x-3 = 0\\x = 3\\2x-8 = 0\\2x = 8\\\frac{2x}{2} = \frac{8}{2}\\x = 4[/tex]

We get two values for x, x=3 and x=4

Hence,

The zeroes of the function are: 3 and 4

Answer:

2.3 mL

Step-by-step explanation:

This is called finding the volume by displacement. By subtracting the final volume and the initial volume you can determine how much the volume changed when the object was added. That change in voulme represents the volume of the object, so in this case:\

14.5-12.2 = 2.3 mL

The change in the volume of the object is, 2.3 mL.

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

We have to given that;

An object placed in a graduated cylinder raised the volume from 12.2 mL to 14.5 mL .

Here, An object placed in a graduated cylinder raised the volume from 12.2 mL to 14.5 mL .

Hence, The change in the volume of the object is,

⇒ 14.5 - 12.2 mL

⇒ 2.3 mL
