I need help with my science work

Answer:

16 in.

Step-by-step explanation:

Notice that 20*1.5 = 30

Use this ratio for 24 except reverse.

16*1.5 = 24

Hope this helps! Have a nice day!

Answer:

16

Step-by-step explanation:

Real length: 30 ft

Drawing length: 20 in.

Real width: 24 ft

Drawing width: x

30/20 = 24/x

3/2 = 24/x

1/2 = 8/x

x = 2 * 8

x = 16

Answer: 16

Answer:

240

Step-by-step explanation:

If the length of the drawing is 36cm, then we divide 36 by 6, which then equals 6...

Since we changed the 6,  we have to change the 40...

40 x 6 = 240

so the ratio is 36:240 and the object's length equals 240cm

The equivalent equation for the given equation is b=8/(a-3).

Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value.

The given equation is ab-8=3b.

Now, transpose 3b to other sides of an equation, we get

ab-3b=8

b(a-3)=8

b=8/(a-3)

Therefore, the equivalent equation for the given equation is b=8/(a-3).

Answer:

what grade are you

Step-by-step explanation:

Answer:

1) B is the answer

2) C is the answer

Step-by-step explanation:

1) 21:40=0.525

2) 21:40=0.525=52.5%

Because with percents it has to be out of 100 so 0.525 is not out of a hundred so multiply 0.525 times 100 to get 53.5%.

Answer:

-2

Step-by-step explanation:

you do -4+-6+2+6

First, we must determine slope using the given points and pluging them in the slope formula*.

[tex]m = \frac{6 - (-6)}{2 - (-4)} = \frac{12}{6} = 2[/tex]

The slope is 2. You can prove this by using the graph.

Second, we plug in the slope we found, and one of the given points to solve for b using slope-intercept form**.

[tex]6 = 2(2) + b\\\\6 = 4 + b\\\\2 = b[/tex]

The y-intercept (or b) is 2. You can prove this by using the graph.

Finally, we can now create the equation of the line in slope-intercept form.

[tex]y = 2x + 3[/tex]

*Slope formula: y₂ - y₁/x₂ - x₁

**Slope-intercept form: y = mx + b

Answer:

the answer you are looking for is letter C

Answer:

I think it should be (-1,-5)

Step-by-step explanation:

On a coordinate grid, when you flip this coordinate across the x-axis, the x-axis number won't change, meaning that -1 will stay. The intial number was in the second quadrant, this means that the new number will be in the third quadrant which is made up of all negative numbers. This means that 5 will now be graphed as negative 5, making (-1,-5) the correct answer in this situation.
