Answer: I believe  that A is the function to this problem

Step-by-step explanation:

Answer:

1 - A is not a function

2 - B is not a function

3 - A is not a function

X can have only 1 value

for example 2B features x=5 where f(x) = -4 but also 1. That means it's not a function

Answer:276+z= 87+n

Step-by-step explanation:

Answer:  The slope is 6.

Step-by-step explanation:

One way to see the slope is to look at the graph and find places where the graphed line crosses the corners formed by the grid lines. Then count the number from top to bottom and divide that number by the number of blocks left to right  (IF the scale is the same for both the x-axis and y-axis!) Then divide up-down number by left-right number. If it is the same, the slope is 1.

Here the line crosses the y axis at -1 exactly: (0, -1) The next place where it crosses the corner exactly is at (1, 5). Counting blocks:  6 from top to bottom, only 1 left to right  6/1

Or do it with the numbers: Find the difference in y-values, them divide by the difference in x-values, Using Coordinates (0,-1) and (1,5)  the difference in y-values is 5-(-1) = 5+1 = 6 The difference in x-values is 1 - 0 = 1   6÷1 = 6

Answer:

a. 3.1 acres

b. 7.44 acres

Step-by-step explanation:

a.

0.25 can also be written as 25%

to find 25% of 12.4 do:

25/100 * 12.4 (cross multiply by 4)

= 25/25 * 3.1

= 1 *3.1

= 3.1

b.

0.6 * 12.4

= 7.44

Negative 3, negative 2.4, negative 1.5, negative 2 and one-fourth, negative 1 and one-eighth

Explanation:

Let's rewrite each given fraction with a common denominator of 5*7 = 35.

1/5 = (1/5)*(7/7) = 7/35

1/7 = (1/7)*(5/5) = 5/35

Then we can see that 6/35 is between 5/35 and 7/35, since 6 is between 5 and 7.

Put another way:  5/35 < 6/35 < 7/35 since 5 < 6 < 7

This then means 1/7 < 6/35 < 1/5

Therefore, Maria's claim is incorrect.

Answer:

160° (But you should input the answer as 160 as the instructions say)

Step-by-step explanation:

We know that the interior angles of a triangle add up to 180°. In this case, (interior) angles A, B, and C. For those three angles, we are given only A and B. Let's solve for C.

First, let's set up an equation with our given values:

--------------------------------------------------------------------------------------------------------------

m∠A + m∠B + m∠C = 180°

Plug in our known values:

↓

(5x - 10)° + (12x)° + m∠C = 180°

Let's call m∠C just InC (to stand for interior C) for now and solve the equation for InC:

↓

Combine the x's

(5x + 12x) -10 + InC = 180

↓

17x - 10 + InC = 180

(-17x + 10)               (-17x + 10)

↓

InC = 190 - 17x

--------------------------------------------------------------------------------------------------------------

Okay, so what we've got for InC looks pretty confusing at first. You're probably wondering what the heck we're supposed to do with this weird value. Well, this is where the exterior C angle the problem gives us comes in handy:

We can see that line AC is a straight line, which means InC and the exterior C angle are supplementary angles, or that they add up to 180°.

Looks like it's time to solve for another equation now that we know this!

--------------------------------------------------------------------------------------------------------------

We'll call the exterior C angle ExC. So:

InC + ExC = 180°

Well, look at that! The good news is, we've already got a value for InC (from the previous equation we just solved) AND ExC (the question tells us).

That means all we need to do is plug this in and solve for x! Let's go:

↓

InC + ExC = 180°

Plug in our known values:

↓

(190 - 17x) + 16x = 180°

Combine the x's:

↓

(-17x +16x) + 190 = 180°

↓

Isolate x:

-x + 190 = 180

(-190)        (-190)

↓

-x = -10

Multiply both sides by -1 to cancel:

↓

x = 10

--------------------------------------------------------------------------------------------------------------

Yay, we've got x!

Now, be careful not to fall for the trick of putting the value of x for your answer. Remember, they're asking for the value of the exterior angle at C.

Well, we know that the exterior angle at C equals 16x, AND we've figured out the value of x. All we have to do is plug in our value:

↓

16 * 10 = 160°

↓

There it is! 160° is our value of the exterior angle at C

--------------------------------------------------------------------------------------------------------------

From here on, we're just going to double-check our answer to be sure! You can skip it if you would like.

So, what we're going to do to make sure that we got the right value for x is plug it into the values of m∠A, m∠B, and m∠C. If the three numbers add up to 180° (and if m∠C and the exterior angle at C equal 180°), then we're 100% correct :)

Let's see if the triangle adds up to 180° first:

↓

m∠A = 5x - 10

Let's plug in 10 into x (since that's the value we calculated for x):

↓

m∠A = 5(10) - 10

↓

m∠A = 50 - 10 = 40

↓

m∠A = 40°

-------------------------------

m∠B = 12x

↓

m∠B = 12(10) = 120

↓

m∠B = 120°

-------------------------------

Let's use the value of InC we calculated in the very first equation we did as our value of m∠C:

m∠C = 190 - 17x

↓

m∠C = 190 - 17(10)

↓

m∠C = 190 - 170 = 20

↓

m∠C = 20°

-------------------------------

Now:

m∠A + m∠B + m∠C = 40° + 120° + 20°

↓

= 180°

--------------------------------------------------------

Woo! Look's like we're right after all. While we're at it, why don't we do the "m∠C and the exterior angle at C equal 180°" check I mentioned too:

↓

Since we just solved for the value of x, we can already see that 20° + 160° = 180°, so this double-check method also tells us we're right, but let's pretend that we haven't done the first double-check method and therefore don't know what m∠C equals:

↓

m∠C + Exterior Angle at C = 180°    (because they're supplementary angles)

↓

We'll plug in the original value of InC for m∠C, and of course our answer for the questions for "Exterior Angle at C":

(190 - 17x) + 160 = 180°

Plug in our known value of x:

↓

(190 - 17(10)) + 160 = 180

↓

(190 - 170) + 160 = 180

↓

20 + 160 = 180

↓

180 = 180

--------------------------------------------------------

So, now that we've double-checked our answer twice, we can be sure that 160° is the correct answer! You don't have to double-check your answer all the time, but these are the double-check methods if you're ever unsure about your answer.

And we're finally finished! If you have any more questions about this problem (I didn't completely explain things that I felt you might already know), please comment, and I will answer as soon as possible!

The number of cookies prepared in an hour is \(3\frac{27}{32}\) cookies.

Given that, 8 ⅕ cookies can make in 1 ¹/₃ of an hour.

Here, 8 ⅕ can be written as 41/8 and 1 ¹/₃ can be written as 4/3.

Now, unit rate = Number of cookies/Number of hours

= 41/8 ÷ 4/3

= 41/8 × 3/4

= 123/32

= \(3\frac{27}{32}\)

Therefore, the number of cookies prepared in an hour is \(3\frac{27}{32}\) cookies.

Answer:

Mean is 69 to get the mean you have to add all the numbers up and then count how many numbers there are all together and then divide it by the sum you got. The median is 70 to get the median you have to arrange all the numbers from least to greatest and then see which one is in the middle if there are 2 numbers then add them up and divide by 2 thats what I had to do to get 70. The mode is the most frequent number so the mode would be 71. That's all I can do for you I do not know the others sorry but hope this at least helped!

20% of 16 = 3.2

3.2 + 16 = 19.20

7.5% of 19.20 = 1.44

1.44 x 2 = 2.88

19.20 x 2 = 38.4

38.4 + 2.88 = 41.28

Firstly, brainly allows 1 question per question. So do not try this again.

Lets make the fractions all like terms.

242/4 - 37/4=205/4. Lets now make this a mixed fraction.
By doing 205/4, we find out that 4 goes in less than 51 times.

1. 51  1/4.

2. 11/2 = 66/12.....so 66/12 - 29/12= 37/12. Make it mixed fraction: 3 1/12.

3. 36/5=72/10.      72/10 - 37/10 = 35/10. As a mixed it is 3 1/2

4. 35/3 - 17/2 can be rewritten by finding their GCM (Greatest Common Multiple). In this case it is 6.

70/6 - 51/6 = 19/6. 3 1/6.
