Answer:

A)  10[tex]\sqrt{2}[/tex]

Step-by-step explanation:

this is an isosceles triangle because it has 2 equal sides

it is also a 45-45-90° triangle because the right angle measures 90° so the sum of the other two equal angles must be 90°; therefore each base angle measures 45°

the sides of a 45-45-90° triangle, respectively, have a ratio of 1 to [tex]\sqrt{2}[/tex]

so if the legs are 10 then 'x' must be 10[tex]\sqrt{2}[/tex]

Instead of explaining why D is right, I will explain why A, B, and C are wrong.

A) Speed does not apply to graphs unless that is the x or y value.

B) Constant slopes only apply to linear graphs, in which the only change would be a constant one.

Step-by-step explanation:

A company shipped a certain amount of books to a school. The books

were shipped in large boxes that are 25 in. X 10 in. X 12 in. The books are

all 5 in. X 4 in. X 3in. How many of these books did the school receive if

there were 50 large boxes in the shipment?

the first step is figure out how many books fit in one box so here is how to calculate that!  

(5 in.) x (4 in.) x (3 in.)                                           (25 in.) x (10 in.) x (12 in.)

=983 milliliters                                               =49 liters

so in that case how many milliliters can go into 49 liters? the answer is this 49,161 so divide that by the volume of the books

20 books should fit in each box

the school got a shipment of 1000 books

Answer:

(x, y) = (3, 5/2)

Step-by-step explanation:

[tex]4x+2y=17\\3x+2y=14[/tex]

I'll solve by elimination here. If you invert the second equation and add it to the first, 2y and -2y would cancel out.

[tex]4x+2y=17\\-(3x+2y=14)[/tex]

Now just add those from top to bottom.

[tex]\rightarrow (4x-3x)+(2y-2y)=17-14\\\rightarrow x=3[/tex]

Nothing else needs to be done for that part. Now, you can pick either equation and use the known value of x to solve for y.

[tex]4x+2y=17\\\rightarrow 4(3)+2y=17\\\rightarrow 12+2y=17\\\rightarrow 2y=5\\\rightarrow y=\frac{5}{2}[/tex]

The surface area of a shape is the amount of space on it

The surface area of the hexagonal prism is 189.9 square millimeter

The given parameters are:

Side length : l = 4.2 mm

Height: h = 3.9 mm

Base area: A = 45.8 square mm

The surface area is then calculated as:

[tex]SA = 6lh + 3l^2\sqrt {3[/tex]

So, we have:

[tex]SA = 6 * 4.2 * 3.9 + 3 * 4.2^2\sqrt {3[/tex]

Evaluate

[tex]SA = 189.9[/tex]

Hence, the surface area of the hexagonal prism is 189.9 square millimeter

Step-by-step explanation:

Answer:

C.

Step-by-step explanation:

If each pack had 5 pieces, that would mean that every pack (p) would equal 5•p, or 5p. The question is asking how many total pieces she has. So if 5 pieces equals one pack, you would have to add the pieces she previously had to add those to 5p. We don't know how many packs she bought, so we would have to replace that number with a variable (p). So 5p + 3

The true statements are:

The question is an illustration of a linear function; a linear function is a function that has a constant rate/slope

A linear function is represented as:

[tex]y=mx + c[/tex]

Where

Start by calculating the slope using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{51 - 15.75}{4 -1}[/tex]

[tex]m = 11.75[/tex]

The linear equation is then calculated as:

[tex]y=m(x -x_1) + y_1[/tex]

So, we have:

[tex]y=11.75(x -1) + 15.75[/tex]

[tex]y=11.75x -11.75 + 15.75[/tex]

[tex]y=11.75x +4[/tex]

Start by calculating the slope using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{57 - 26.25}{4 -1}[/tex]

[tex]m = 10.25[/tex]

The linear equation is then calculated as:

[tex]y=m(x -x_1) + y_1[/tex]

So, we have:

[tex]y=10.25(x -1) + 26.25[/tex]

[tex]y=10.25x -10.25 + 26.25[/tex]

[tex]y=10.25x+16[/tex]

To do this, we simply equate both equations

[tex]11.75x +4 = 10.25x + 16[/tex]

Collect like terms

[tex]11.75x -10.25x = -4+ 16[/tex]

[tex]1.5x = 12[/tex]

Solve for x

[tex]x = 8[/tex]

Substitute 8 for x in any of the equations.

[tex]y=11.75 \times 8 +4[/tex]

[tex]y=98[/tex]

Hence, the price of both products will be the same at $98.00

You can convert from scientific notation to simple notation using the fact that negative powers can be converted to division.

The correct option is given by

Option C. The greatest number is 8. 2 × 10-3. It is 2,000 times greater than the smallest number.

Suppose you have got [tex]a^{-b}[/tex]

Then we have

[tex]a^{-b} = \dfrac{1}{a^b}[/tex]

[tex]8.2 \times 10^{-3} = \dfrac{8.2}{10^3} = \dfrac{8.2}{1000} = 0.0082\\\\5.2 \times 10^{-6} = \dfrac{5.2}{10^6} = \dfrac{5.2}{1000000} = 0.0000052\\\\4.1 \times 10^{-6} = \dfrac{4.1}{10^6} = \dfrac{4.1}{1000000} = 0.0000041[/tex]

Thus, we can see that

The greatest number among given numbers is [tex]8.2 \times 10^{-3}[/tex]

The smallest number among the given numbers is [tex]4.1 \times 10^{-6}[/tex]

Dividing greatest number by smallest to see how many times the greatest number is greater than the smallest number

[tex]\dfrac{8.2 \times 10^{-3}}{4.1 \times 10^{-6}} =\dfrac{8.2}{4.1} \times \dfrac{10^{-3}}{10^{-6}} = 2 \times 10^{-3 - (-6)} = 2 \times 10^3 = 2000[/tex]

Remember that when base are same, and there is division, then power gets subtracted, that's why we got [tex]\dfrac{10^{-3}}{10^{-6}} = 10^{-3 - (-6)} = 10^3[/tex]

Thus, we have the greatest number 2000 times bigger than the smallest number among the numbers given.

Thus, the correct option is

Option C. The greatest number is 8. 2 × [tex]10^{-3}[/tex]. It is 2,000 times greater than the smallest number.
