Answer:

x = 14

Step-by-step explanation:

146° = 9x + 20°

146° - 20° = 9x

126° = 9x

x = 126°/9

x = 14

Answer:

2.1 cups per day and you will run out of juice in 5 days.

Step-by-step explanation:

1.2 cups + .9 cups = 2.1 cups per day

10.5 divided by 2.1 = 5 days

From the equation calculated, 2.1 cups of juice will be drank daily.

The total juice that will be drank each day will be:

= 1.2 + 0.9 = 2.1

Therefore, 2.1 cups of juice will be drank daily.

The number of days before the person runs out of drink will be:

= 10.5 / 2.1

= 5

The person will use 5 days before running out of drink.

Answer:

59%

Step-by-step explanation:

No. of squares in a whole = 10*10=100

No. of spaces shaded = 59

No. of spaces not shaded = 41

Hence, percent represented by the shaded area = 59%

Answer:

First box plot

Step-by-step explanation:

In the figure attached, the options are shown.

The left end of the box is the lower quartile (also called quartile 1 or Q1)

The right end of the box is the upper quartile (also called quartile 3 or Q3)}

The interquartile range (IQR) is computed as follows:

IQR = Q3 - Q1

If Q1 = 3 and IQR = 5, then Q3 = 5 + 3 = 8

The first box plot is the only one with a lower quartile of 3 and an interquartile range of 5

The box plot that could represent a data set that has an interquartile range of 5 is the box plot shown in the image attached below (see attachment).

Interquartile range (IQR) of a data set is the distance between the lower quartile (Q1) and the upper quartile (Q3) on a box plot.

Thus, a box plot that has a lower quartile of 3 and interquartile range of 5 will have a distance of 5 from the lower quartile to the upper quartile.

Therefore, the box plot that could represent a data set that has an interquartile range of 5 is the box plot shown in the image attached below (see attachment).

13-B $11.46

Step-by-step explanation:

I tend to think of parallel lines as train tracks (the metal rail part anyway). Inside the train tracks is the interior region, while outside the train tracks is the exterior region. Alternate exterior angles are found here. Specifically they are angles that are on opposite or alternate sides of the transversal cut.

Both pairs of alternate exterior angles are shown in the diagram below. They are color coded to help show how they pair up and which are congruent.

A thing to notice: choices B, C, and D all have point W as the vertex of the angles. This means that the angles somehow touch or are adjacent in some way due to this shared vertex point. However, alternate exterior angles never touch because parallel lines never do so either. We can rule out choices B,C,D from this reasoning alone. We cannot have both alternate exterior angles on the same exterior side of the train tracks. Both sides must be accounted for.

Step-by-step explanation:

The surface area of a rectangular pyramid is formed by one rectangle at the center, and four triangles attached to it.

In this case, the rectangle has dimensions of 10 inches (height) by 4 inches (length). 2 triangles have a base of 10 inches and a height of 5 inches. The other 2 triangles have a an area of 13.6 square inches.

Basically, we need to find the area of the other two triangles and the area of the rectangle at the center.

[tex]A_{1}=4 \times 10 = 40 \ in^{2}[/tex]

[tex]A_{2}= 2(\frac{1}{2} \times 10 \times 5 )=2(25) \ in^{2} = 50 \ in^{2}[/tex]

Now, we sum all areas

[tex]A=40 + 50 + 13.6 +13.6= 117.2 \ in^{2}[/tex]

Therefore, the total surface area is 117.2 square inches.

The answer is 117.2 square in

Answer:

5 to 1.

Step-by-step explanation:

There are 5 unshaded and one shaded section so it's

5:1.

The ratio of unshaded sections to shaded sections is;

Option D; 5 to 1

We are told that the diagram is divided into equal parts.

Now, from the given, we can see that there are 6 equal parts. However, out of the 6 equal sections, only one section is shaded while 5 sections are unshaded.

This means that the ratio of unshaded sections to shaded sections is; 5 to 1.

In conclusion, the ratio of unshaded sections to shaded sections from the given diagram that was divided into equal parts is; 5 to 1.

Correct question:

Evaluate the expression below for x = 2, y = –3, and z = –1.

Given: [tex] x^2 z^2 -y^2(x+z) [/tex]

Options:

A.–23

B.–5

C.13

D.27

Answer:

B. -5

Step-by-step explanation:

In this question we are given the following values:

x = 2

y = -3

z = -1

Given the expression:

[tex] x^2 z^2 -y^2(x+z) [/tex]

To evaluate, let's substitute for 2, -3 & - 1 for x, y & z respectively

Therefore,

[tex] x^2 z^2 -y^2(x+z) [/tex]

Substituting values, we have:

[tex] (2^2) (-1^2) - (-3^2)(2+(-1)) [/tex]

Simplifying, we have:

[tex] [(2^2) (-1^2)] - [(-3^2)(2-1)] [/tex]

[tex]= [(4) (1)] - [(9)(1)] [/tex]

[tex]= 4 - 9[/tex]

To solve you can use inverse operations.

Here are the steps to find the answer:

1. Write out the equation: -6(x-2)+3x= -3(x+3) +21

2. Distribute both sides: -6x+12+3x= -3x-9+21

3. Simplify both sides: -3x+12=-3x+12

4. This equation is true for all values, or infinity, because the equation is the same on both sides

Answer:b

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Answer:

The sides are 3 and 9

Step-by-step explanation:

Since this is a right triangle, we can use the pythagorean theorem

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

x^2 + (3x)^2 = (3 sqrt(10))^2

x^2 + 9x^2 = 9*10

10x^2 = 90

Divide each side by 10

x^2 = 90/10

x^2 =9

Take the square root of each side

x = sqrt(9)

x = 3

The sides are x=3  and 3x = 3(3) = 9

Answer: x=10

Step-by-step explanation:

Since the original statements were x, 3x, and 3[tex]\sqrt{x}[/tex], is already given as 10 in 3[tex]\sqrt{x}[/tex], therefore, 3x is 3*10 and x is 10

Answer:

[tex]\frac{\sqrt{8} }{\sqrt{10} }[/tex]

Step-by-step explanation:

A perfect square is a number that has two identical factors, meaning it can be square rooted. The numbers 64 and 100 are an example:

8 · 8 = 64

10 · 10 = 100

So when you take the square root of [tex]\frac{64}{100}[/tex], you get:

[tex]\frac{\sqrt{8} }{\sqrt{10} }[/tex]

It doesn't say to simplify, so we can just leave it at that.

6 cube/to the 3rd units

Step-by-step explanation:

um idk if this is what you want but yeah

if you spilt it into a 2x2x1 and a 1x2x1 you can count that there are 6 cube units

Answer:6 cubes

Step-by-step explanation:

There are 2 ways that I think you could solve this.

1. First, you could make those 2 missing cubes actual cubes, so then you could find the volume of the cube by doing 2x2x2(length x width x height) and you would get 8 cubes. After that, you would take away the two missing cubes, and you would get 6 cubes.

2. You could also just count the cubes. I counted the two inner cubes and then counted the 4 outer cubes, and got 6 cubes.
