Answer:

slope is 2

Step-by-step explanation:

Pick any two points

say point (0,0) and point (2, 4)

to find slope, subtract the x and y coordinates as a fraction.

y on the top, x on the bottom

y/x = (4 -0)/ (2-0) = 4/2 = 2

Answer:

actual area = 900 square feet

ratio = 1cm2 : 36ft2

Step-by-step explanation:

square room

area = 25cm2

1 side =  √ 25

         =  5cm

1cm = 6ft

5cm = 5 x 6

      = 30ft = 1 side

actual area = 30 x 30 = 900ft

ratio = square cm : square feet

       = 25     :     900  ( simplify both ratio )

      = 1cm2  :  36ft2

Answer:

In simplified form, sin D is;

4/5

Step-by-step explanation:

The given figure and dimension parameters in the question are;

Triangle ΔDEF is a right triangle

The length of leg [tex]\overline{EF}[/tex] which is opposite side to the reference angle = 20

The length of segment [tex]\overline{ED}[/tex] which is the hypotenuse side of the right triangle ΔDEF = 25

The length of segment [tex]\overline{DF}[/tex] which is adjacent side to the reference angle = 15

By trigonometric ratios, we have;

[tex]sin\angle X = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]

Therefore, we have;

[tex]sin\angle D = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length} = \dfrac{20}{25} = \dfrac{4}{5}[/tex]

∴ In simplified form, sin(D) = 4/5.

Answer:

11. x = 5

12. x = 24

Step-by-step explanation:

11.

8x° + 140° = 180°

(Linear pair angles)

8x° = 180° - 140°

8x° = 40°

x ° = 40°/8

x° = 5°

x = 5

12.

2x° + 42° = 90°

(complementary angles)

2x° = 90° - 42°

2x° = 48°

x ° = 48°/2

x° = 24°

x = 24

Answer:

497.39 FEET

Step-by-step explanation:

Please check the attached image for a diagram of the bearings

This question can be solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

we want to determine the value of c

250² + 430² = 247400

c = √247400 = 497.39 feet

Answer:

The correct answer is C. That problem best represent x - 15 =60.

Answer:

C

Step-by-step explanation:

So lets look at the first equation.

This would represent 60-15=x

This is because 60 shells minus 15 shells she gave away.

Next is B, whihc is also 60-15=x

This is because Mr yungs brother is 60 years old and mr yung is 15 years younger.

Next is c, whihc is 60+15=x

This is because they had 60, gave 15 already, and want to find out what they started with.

FInally we are left with d.

This is 15+x=60

Well...none of those look like x-15=60

But lets go back to c:

60+15=x

Lets try to rwwrite this.

Subtract 15 from both sides, and you get:

60=x-15

Just make this proper by putting the x-15 before the 60:

x-15=60

That looks like x-15=60

Now we know our answer!

C

Hope this helps ;)

$0.09 × 100 = 9

$62.47 × 4 = 249.88

249.88 + 9 = 258.88

Answer:

D

Step-by-step explanation:

To solve this question we can use the area formula for an octagon.

It is as follows:

A=2(1+√2)a^2

where "A" is the total area and "a" is the length of a side.

Plug in our side length a=10.4

A=2(1+√2)10.4^2

≈522.24268

Alternatively, you can split the octagon into 8 equal triangles.

The base of each triangle would be 10.4 and the height would be 12.5 since opposite sides are 25 feet apart. (25/2)

The area of a triangle would then be:

A=1/2bh

where "b" is base and "h" is height

A=125*10.4*1/2

=65

Since there are 8 we multiply that by 8 for the area of an octagon

65*8=520

The area of the octagon base is 520 square feet.

I'll use this value to do my calculations as it is more exact.

Now, using this area, we need to find the volume of the pool we are meant to fill.

To do this, we simply multiply the area of the base by the height.

520*3=1560

Now, we know that the volume of the pool is 1560 cubic feet.

Each cubic foot takes 7.5 gallons to fill.

1560*7.5=11700

Therefore, the pool takes 11700 gallons of water to fill.

12x^3+x^2-9x+2

Step-by-step explanation:

(12x^2-8x-3x+2)(x+1)

(12x^2+(-8x-3x)+2)(x+1)

(12x^2-11x+2)(x+1)

12x^2(x+1)-11x(x+1)+2(x+1)

12x^3+12x^2-11x(x+1)+2(x+1)

12x^3+12x^2-(11x^2+11x)+2(x+1)

12x^3+12x^2-11x^2-11x+2x+2

12x^3+(12x^2-11x^2)+(-11x+2x)+2

12x^3+x^2-9x+2
