Answer:

102°

Step-by-step explanation:

Triangle has 180 degrees

We know the degree values of two angles already.

50+28+x=180

x=180-50-28

x=102

The 3 inside angles need to equal 180 when added together

angle B = 180 - 50 -28 = 102

answer: angle B = 102 degrees

5/9 + 4/9 = 1

So your answer is D

Answer:

Step-by-step explanation:

In the question we are given two fraction that are ,

And we have asked to add the fraction and reduce them to their lowest terms. So , Starting Solution :

[tex] \longmapsto \: \frac{5}{9} + \frac{4}{9} [/tex]

Step 1 : As we can see that denominator of both the fraction is same i.e. 9 . So simply adding the equation :

[tex] \longmapsto \: \frac{5 + 4}{9} [/tex]

[tex] \longmapsto \: \cancel{\frac{9}{9} }[/tex]

Step 2 : Now dividing 9 by 9 to get 1 :

[tex] \longmapsto \: \pink{ \boxed{1}}[/tex]

Answer:

Step-by-step explanation:

Answer:

A. 2

Step-by-step explanation:

To add fractions we make them have a common denominator, since these fractions already do we don't have to worry about that. Next, we add up the nominators, so 9 + 5 which equals 14. So 14/7, now we simplify, since 7 is half of 14 when we simplify we get 2/1 or 2. So A would be the correct answer. Hope this helps!

Answer:

3) 27 cubed

4) 72 cubed

5) 125 cubed

8) 27 cubed. 3 is the length, 3 is the width, and 3 is the height.

9) 72 cubed. 6 is the length, 3 is the width, and 4 is the height.

10) 125 cubed. 5 is the length, 5 is the width, and 5 is the height.

Step-by-step explanation

Here's what to show if your teacher requires for you to show your work.

3) 3 x 3 x 3 = 27

4) 6 x 3 x 4 = 72

5) 5 x 5 x 5 = 125

8) 3 x 3 x 3 = 27

9) 6 x 3 x 4 = 72

10) 5 x 5 x 5 = 125

These are the ones I'd suggest putting the up and down form on.

10) and 5) Also put 5 x 5 = 25.          4) and 9) Also put 6 x 3 = 18.

     2                                                        3

     25                                                      18

  x  5                                                     x 4  

   125                                                      72

Answer:

  147 square meters

Step-by-step explanation:

You want the area of the given irregular figure.

The figure can be divided by a couple of lines into two rectangles and a triangle as shown in the attachment.

The area of a rectangle is the product of its length and width. The upper rectangle is 9 m wide and 4 m high, so has an area ...

  A = LW = (9 m)(4 m) = 36 m²

The lower rectangle is 3 m wide and 7 m high, so has an area ...

  A = (7 m)(3 m) = 21 m²

The triangle has a base of 18 m and a height of 10 m, so an area of ...

  A = 1/2bh

  A = 1/2(18 m)(10 m) = 90 m²

The area of the entire figure is the sum of the areas of its parts. That is ...

  total are = 36 m² +21 m² +90 m² = 147 m²

The area of the figure is 147 square meters.

[tex]5\sqrt{96}[/tex].
I converted it into decimal form with a calculator and got approximately 48.9898

And if you round that, you will get the 49, which fits the inequality of

45<  [tex]5\sqrt{96}[/tex] < 50 since it becomes 45 < 49 < 50 which is true

Step-by-step explanation:

I got it through division but without remainders.

1. Divide the anwser with Does Mcdonalds Sell Burgers?

Divide the number multiply closest to it subtract both numbers then bring down the next repeat until you get the answer.

2. Round up so there isnt a remiander.

Answer:

1. y= |x| -15

2. y = -|x| +3

Step-by-step explanation

.The V shape means absolute value (the | | ), since its upside down, the equation has to be negative. The tip of the V doesn't start at 0 like normal, it's up 3, so the equation has a +3 at the end. The x intercept at (3, 0) is just so you can check your work. If we plug in 3 for x, we do in fact get 0 for y.

Not sure, if correct but here.

Answer:

Step-by-step explanation:

The (positive) slope of the line whose domain is (-infinity, -1) is

m = rise/run = 1/1, or m = 1.  The (negative) slope of the other line segment is

m = rise/run = -1/1, or m = -1.

Let's now find the equation of the line with m = 1.  Using the slope-intercept form, y = mx + b, where m = +1, we get 1 = +1(-1) + b, or b = 2.  Then the equation is y = x + 2 on the domain (-infinity, -1).

Now find the equation of the line with negative slope:

y = -x + b; the y-intercept is immediately evident from the graph as b = 0.

Then the desired eequation is y = -x on the domain (-1, infinity).

Answer:

502.4 units³

The volume of a cylinder is known as the area of the circuar base multiplied by the height of the cylinder.

In the cylinder shown, we can tell that the radius of the circular base is 4 units and the height of the cylinder is 10 units. Therefore,

[tex]\implies\text{Volume of cylinder}: [\pi (4)^{2}] \times [10][/tex]

[tex]\implies\text{Volume of cylinder}: [\pi (16)] \times [10][/tex]

Substituting π as 3.14, we get;

[tex]\implies\text{Volume of cylinder}: [(3.14) (16)] \times [10][/tex]

[tex]\implies\text{Volume of cylinder}: [50.24] \times [10][/tex]

[tex]\implies\boxed{\text{Volume of cylinder}: 502.4 \ \text{units}^{3}}[/tex]

Therefore, the volume of the cylinder is 502.4 units³.

Im not sure but I think its C

Answer:

C

Step-by-step explanation:

Because it is the only one that goes down into a negitive slope, A increases, B is constant (Stays the same), and D increases. so C is also your only option

Answer:

D. The range of the data set is 18.

Step-by-step explanation:

The question asks for the variability of the data.

That means it refers to the range of the data.

It shows how variable the data points in a set are.

Option D is the best answer.

Answer:

Mean: 5.8

Median: 5

Range: 7

Step-by-step explanation:

Arrange the following data set from least to greatest.

2, 3, 3, 4, 4, 6, 9, 9, 9, 9

Mean: Finding the total average of the following data set.

Median: The middle number in the data set

Range: Subtracting the highest and the lowest value from the arranged data set.

Mean: Add all the numbers listed above and divide by the number of numbers in the set (10)

Median: Middle number. No middle number so I chose the number in between 4 and 6 which is 5.
Mode: Subtract smallest number from biggest number (9-2=7)

Step-by-step explanation:

area of a prism is obtained by taking the sum of (twice the base area) and (the lateral surface area of the prism). The surface area of a prism is given as S = (2 × Base Area) + (Base perimeter × height) where "S" is the surface area of the prism.

Answer:what is the hole Qestion? But it’s 12 x 4 = 48 2

Step-by-step explanation:

Answer:

Part A: Variables : M = money, H = number of hours. So the number of hours(H) is independent and the money(M) is a dependent variable.

Part B: Ordered pairs : (0 Hours, 0$), ( 1 Hour, 5$), (2 Hours, 10$)

Part C: H*5 = M

Step-by-step explanation:

Part A: The money is dependent on the number of hours because per hour she paints the fence, she gets 5$. So the hour changes, and because of this, Latisha gets 5$ more.

Part B:  The ordered pairs are in the form (number of hours, money).

Part C: H*5 = M. A few examples of this are 1x5=5, 2x5=10, 10x5=50.

Good Luck!
