Answer:

[tex] \frac{8}{25 } [/tex]

8/25 m³

Step-by-step explanation:

each cubic is 8/125 m³ because 2/5 * 2/5 * 2/5 = 8/125 m³

and there is 5 cubic in this object 5*8/125 = 8/25 m³

Answer:

y = 1/3x - 2

Slope = 1/3

y- intercept = -2

Step-by-step explanation:

To find the slope and y-intercept, first put the equation in y = mx + b format, Where m is your slope and b is your y-intercept.  

Step one:  Subtract x from both sides

To translate x over to the right side of the equation, subtract x from both sides, leaving you with this equation:

x - x -3y = -x + 6; which simplifies to:

-3y = -x + 6

Step Two: Divide Every Term By Negative 3

To get y alone by itself we need to cancel out -3 on the right side of the equation, to do that you must divide every term by negative 3 leaving you with this equation:

[tex]\frac{-3}{-3}[/tex]y = [tex]\frac{-1}{-3}[/tex]x + [tex]\frac{6}{-3}[/tex]; which simplifies to:

y = 1/3x - 2

M, slope, = 1/3

B, y-intercept, = -2

Answer:

1244 Ibf(Pounds force)

Step-by-step explanation:

The formula for Total force on a piston when given the diameter of the bore area =

F = P × π × d²/4

P = 150 lb/sq.In

π = 3.14

d = 3.25 in

Hence,

F = 150 lb/sq.In × 3.14 × 3.25 in /4

= 4974.9375 ÷ 4

= 1243.734375 Ibf(Pounds force)

Approximately = 1244 Ibf(Pounds force)

Answer:

Its C

Step-by-step explanation:

Answer:

C. 3

Step-by-step explanation:

First I'll solve y + 1 = 3x - 12 for y.

y + 1 = 3x - 12 All you need to do for this first part is subtract 1 from both sides.

y = 3x - 12 - 1

y = 3x - 13

I'll use the point for x being 6, and x being 12.

3(6) - 13

18 - 13

5

y is 5 when x is 6. (6, 5)

3(12) - 13

36 - 12

y is 23 when x is 12. (12, 23)

The formula for slope is y2-y1/x2-x1

(23 - 5)/(12 - 6) Subtract 5 from 13, and then subtract 6 from 12.

18/6 Divide 18 by 6.

3

The slope to the line y + 1 = 3(x - 4) is 3, which is C.

Answer:

13

Step-by-step explanation:

To solve the problem, you have to do A squared + B squared = C squared. So for your A and B it doesn't matter what order you put them in. We will do 12 sqaured + 5 squared = C squared. 12 squared is 144 and 5 squared is 25. By adding 144 and 25 together, it gives us 169. When we take the square root of 169, we get 13. 13 is the length of the hypotenuse.

Answer:

Step-by-step explanation:

Here, we need to know about the concept of the alternate interior angle theorem. This says that the alternate interior angle of two parallel lines formed with one transversal is equal. For a more graphical explanation, please refer to the attachment below.

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

Given

∠GBD=4x+84

∠EFC=16x

m∠GBD=m∠EFC

Solve

4x+84=16x ⇔ Given

4x+84-4x=16x-4x ⇔ Subtract 4x on both sides

84=12x ⇔ Simplify

84/12=12x/12 ⇔ Divide 12 on both sides

x=7 ⇔ Simplify

Substitute the x value into each angle expression

∠GBD=4x+84=4(7)+84=28+84=112

∠EFC=16x=16(7)=112

Hope this helps!! :)

Apply the absolute rule:

If |u| <a, a>0 then -a <u < a

|x-4| <9

-9 < x-4 < 9

The correct answer is the second one.

Answer:

y = 19*(8)^x

Step-by-step explanation:

We want to write an equation like:

y = a*b^x

That goes through the points (0, 19) and (3, 9728)

Then, when x = 0, we must have y = 19

Replacing those values in the equation we get:

19 = a*b^0 = a*1 = a

19 = a

Then the equation is:

y = 19*b^x

We also know that when x = 3, y = 9728

If we replace these values in the equation, we get:

9728 = 19*(b)^3

Let's solve this for b.

9728/19 = b^3

512 = b^3

∛512 = b = 8

Then the equation is:

y = 19*(8)^x

A triangular prism and its dimensions are shown in the diagram. What is the lateral surface area of this triangular prism in square centimeters? F 192 cm2 G 128 cm2 H 152 cm2 J 144 cm

Answer:

G

The lateral surface area of the triangular prism is 128 square centimeters. The correct answer would be an option (G) 128 cm².

A triangular prism is a three-sided prism consisting of a triangular base, a translated duplicate, and three faces connecting similar sides.

As per the question, we have dimension are:

side legth of base  = 6 cm, 5 cm, and 5 cm

height = 8 cm

Lateral surface area = (a+b+c)h

Substitute the values and we get

Lateral surface area = (6+5+5)8

Lateral surface area = 16 × 8

Lateral surface area = 128 cm².

Hence, the lateral surface area of the triangular prism is 128 square centimeters.

Answer:

9cm2

Step-by-step explanation:

length of two sides: 3

3 x 3 = 9

Since a square has equal lengths you know for sure that it's 3 on each of the sides since all sides are equal in a square and all sides have 3.

To get an area multiply the two different or same given lengths.

When it gives you one given length in a square know that all sides are equal so you multiply the given length by 2 times.

Answer:

9 cm squared

Step-by-step explanation:

The question asks us to find the area, and the way to find the area is in this formula:

length x width = area

Now we just have to find the length and the width of the square and multiply it to find the area.

If you count two non parallel sides, they both are 3 centimeters. So, we just have to plug that in into the formula:

3 (Length) x 3 (Width) = 9 (area)

So, 9 cm squared is our answer :)

If you look at the sample section of the 5 different prices, you can see that $2,000 is very far away from the rest of the prices, which range from $14,000 to $17,000. This $2,000 is an outlier, and is likely not accurate in predicting reasonable prices for Hank's bike, so it should not be a factor in his decision or contribute to the mean value.
