Answer:

x = 10

The shaded angles are each 31 degrees.

Step-by-step explanation:

I don't know if you are being asked to solve for x or the shaded angle, so we'll solve for both.

Those 2 shaded angles are equal to each other. So set them equal to each other & solve for x.

91-6x = 4x-9

91+9 = 4x+6x

100 = 10x

10 = x

Now substitute x=10 to find the measure of the shaded angles (which are equal).

91-6x = 91-6(10) = 91-60=31

The shaded angles are both 31 degrees .

Answer: IQR= 18

Step-by-step explanation:

First, you need to put the numbers in order from least to greatest, which they already are.

23, 58, 58, 64, 76,87

then, you draw an imaginary line down the middle of the numbers (between 58 and 64), and then you find the number in the middle of these. The Q1 is 58, and the Q3 is 76. In order to find the Interquartile range (IQR), you simply subtract the two.

76-58= 18

And you have your answer

Hope this helps!

Answer:

44

Step-by-step explanation:

First, we need to find the median in the data set.

It's between 58 and 64. To find the median, we add those two numbers and then divide by 2.

58 + 64 = 122

122 ÷ 2 = 61 (Mark this point in between the numbers on the data set)

            median = 61

23, 58, 58, | 64, 76, 87

Now that we have the median, we have to find the upper quartile and the lower quartile in order to find the interquartile range.

Lets find upper quartile first. In order to do that, add up all the numbers to the right of the data set from the median point, then divide by 2.

64 + 76 + 87 = 227

227 ÷ 2 = 113.5

The same goes for the lower quartile (to the left).

23 + 58 + 58 = 139

139 ÷ 2 = 69.5

Lastly, to find the interquartile range, simply subtract the lower quartile from the upper quartile.

113.5 - 69.5 = 44

Therefore interquartile range = 44.

The domain and ranges of 5 emoticons that make a function are (B , Open) , (C , Wink) , (D , Horizontal line) , (E , Smile) , (F , Open smile).

What is a function ?

A function is a relationship between inputs and outputs where each input has precisely one output and the output can be linked to its input.

A set of emoticons are given and we have to make a list of 5 emoticons that make a function.

We know that domain is the set of values that we plug into our function. So , here the domain are the names of emoticons i.e., B , C , D , etc. Let's choose 5 emoticons :

B , C , D , E and G

The domain will be :

D = (B, C , D , E , G)

And ranges are the set of values which comes out as the output of the domains we have entered. Ranges here are shapes of emoticons.

So , the ranges for B , C , D , E and G will be :

Open , Wink , Horizontal line , Smile , Open smile.

So , the domain and ranges of 5 emoticons are as follows :

(B , Open) , (C , Wink) , (D , Horizontal line) , (E , Smile) , (F , Open smile)

Therefore , the domain and ranges of 5 emoticons that make a function are (B , Open) , (C , Wink) , (D , Horizontal line) , (E , Smile) , (F , Open smile).

Answer: B

The best type of graph to show changes over time is a line graph. A line graph is ideal for displaying trends and variations in data over a continuous period. It consists of a series of data points connected by line segments, allowing for a clear visualization of how values change over time. Bar graphs, histograms, and circle graphs are better suited for other types of data analysis, such as comparing categories or showing proportions.

Answer:

-{2√7} or {2√7}

Step-by-step explanation:

1) Simplify the exponents 6^2 and 8^2 by multiplying 6*6=36 and 8*8=64.

2) Write an equation, 36+b^2=64

3) Subtract 36 from both sides, b^2=28

4) Apply a square root to both sides, √(b^2)=√(28)

5) Simplify the equation, b=-√(28) or b=√28

6) If you want, factor the square root by finding a factor that is a square number, -{√(4)*√7} or  {√(4)*√7};  -{2√7} or {2√7}

Step-by-step explanation

The domain is the values on the x-axis for the graph notice that the graph starts at (0,75) so x is going to be greater than or equal to zero

The range is the values on the y-axis for the graph so the values for y on the graph are greater than or equal to 75  

This is a Linear graph so the x values will increase from 0 to infinity in the positive direction

and the Y-value will increase from 75 to infinity

The line is positive Linear graph reading from left to right so both Y and X values increase in the positive direction.

Answer:

56 \(in^2\)

Step-by-step explanation:

We can first break this down into 2 smaller rectangles.

1x2x4 rectangle

4x3x4 rectangle.

Then we can find out the area of each, and we get 8+48 = 56.

You also could find this out by subtracting the area that is missing.

Answer:

The volume of the container is 56 in^3

Step-by-step explanation:

To solve, I split this figure vertically at the corner between the two steps. We know that the formula for volume of a container is V= l*w*h. The first, smaller portion of the container has a length of 4, a width of 1, and a height of 2. 4*1*2= 8 in^3

The second, larger portion of this container has a length of 4, (look at the side of the first portion), a width of 3, (4-1=3), and a height of 4. 4*3*4= 48 in^3.

Finally, add together the volumes of the two portions and that is the volume of the whole figure. V= 56 in^3

Answer:

275/9

Step-by-step explanation:

9/10x + 4/5 = 28.3

leave out the decimal sign in 28.3 and then turn it into a fraction.

9/10x + 4/5 = 283/10

Multiply them by 10

9/10x • 10 = 9x

4/5 • 10 = 8

283/10 • 10 = 283

9x + 8 = 283

Separate the x from the non x

9x = 283 - 8

= 275

9x = 275

275/9 = x

The solution to the equation 9/10 x+4/5=28.3 is x = 275/9, Option B is correct.

Two or more expressions with an Equal sign is called as Equation.

The given equation is 9/10 x+4/5=28.3

Nine by ten times of x plus four by five equal to twenty eight point three

x is the variable in the equation

We have to solve for x

Subtract 4/5 from both sides

9/10x = 28.3 - 4/5

9/10x= 28.3 -0.8

9/10x=27.5

9x=27.5×10

9x=275

Divide both sides by 9

x=275/9

Hence, the solution to the equation 9/10 x+4/5=28.3 is x = 275/9, Option B is correct.

Answer:

-81/3+32/5

-81×5+32×3/15

-243+96/15

-147/15

-49/5 Ans

To answer your question ("do you multiply the whole number too?"): Yes, you have to multiply the whole number as well. You can't just separate 1/3 from -8 and multiply it with 2/5, because the whole number is part of the mixed #. Whenever you multiply, add, divide, subtract, or do anything to two mixed numbers, you must include the whole term.

- - - - - - - - - -

Now your question is addition. Like I said, when you add them together, the whole number and the fractions count as one term.

So basically, -8 1/3 + 3 2/5...

- - - - - - - - - -

1) Find the LCM (least common multiple) of the denominators

The LCM of 3 and 5 is 15. To get from 3 to 15, you have to multiply 3 by 5. Now multiply the numbers of the fraction part only by 5.

1/3 --> 5/15 (as you can see, 1x5 = 5, 3x5 = 15)

Now for 2/5: To get from 5 to 15, multiply 5 by 3. Do the same thing to the numbers in the fraction

2/5 --> 6/15 (2x3 = 6, 5x3 = 15)

***TO CLARIFY, DO NOT MULTIPLY THE WHOLE TERM BY THE NUMBER***

Right: 2x3 = 6, 5x3 = 15, 6/15

Wrong: 2/5 x 5 = 2

- - - - - - - - - -

2) So now that we found a common denominator, change the two terms to -8 5/15 + 3 6/15 (because we had to find the LCM to make life a lot easier)

- - - - - - - - - -

3) We just add them together. Even though they are a term together, you can split them apart and add them together separately thanks to the commutative property of addition*.

Time to split it apart to make life a whole lot easier. -8 5/15 can be split apart into the two terms -8 and 5/15. For 3 6/15, it can be split into 3 and 5/15.

Two options from here on:

Set up a single equation: Put all the terms into one equation. -8 + 3 + 5/15 + 6/15. Solve by adding all the terms together in whichever order you prefer (again, thanks to the commutative property of addition)

It would result in the answer -4 4/15

Or...

Set up two separate equations: Set up an equation for whole numbers, and another one for fractions.

Equation 1: -8 + 3 = -5

Equation 2: 5/15 + 6/15 = 11/15

(6 + 5 = 11)

And we add the sums together. -5 + 11/15 = -4 4/15

And that's it!

- - - - - - - - - -

*Commutative Property of Addition: The sum of the numbers will NOT change even if you change the order of the addends
