HELP!!! this is due today and i’m super dumb :( pls help me the help will be very much appreciated.

Answer:

A(8)=32cm

B(9)=36cm

C(10)=40cm

Step-by-step explanation:

let 8:9:10=A:B:C

∑ratios=8+9+10=27

Therefore lengths or triangles:-

The acceleration of the block is 13 m/sec².

Acceleration is defined as the rate of change of velocity with respect to time, It is a vector quantity with units of m/sec².

Force = 52 N

Mass of the block = 4kg

Acceleration =?

The formula for the force applied to any object is given by

F = mass *  Acceleration

Substituting the values

52 = 4 * Acceleration

Acceleration = 52 / 4 = 13 m/sec².

Therefore, The acceleration of the block is 13 m/sec².

Answer:

[tex] \rm b = \dfrac{2A }{h} [/tex]

Step-by-step explanation:

[tex] \rm Solve \: for \: b: \\ \rm \longrightarrow A = \dfrac{1}{2} bh \\ \\ \rm A = \dfrac{bh}{2} \: is \: equivalen t \: to \: \dfrac{bh}{2} = A: \\ \rm \longrightarrow \dfrac{bh}{2} = A \\ \\ \rm Divide \: both \: sides \: by \: \dfrac{h}{2} : \\

Answer:

b in terms of A and h will be:

[tex] \boxed{ \rm{b = \frac{2A}{h} }}[/tex]

Step-by-step explanation:

This is basically the formula for finding the area(A) of the triangle in terms of b and h. We have to solve for b in terms of A and h.

[tex] \rm{A = \dfrac{1}{2} bh}[/tex]

Multiplying 2 in the LHS. This is shift because inverse of division is multiplication.

[tex] \rm{2A = bh}[/tex]

Dividing h from both sides,

[tex] \rm{b = \dfrac{2A}{h} }[/tex]

And we are done! :D

Answer:

8. The length of the longest side is 40 ⇒ H

Step-by-step explanation:

8. In the given figure

∵ The triangle has two equal sides 2x + 12 and 5x - 9

→ Equate their expressions to find the value of x

∴ 5x - 9 = 2x + 12

→ Add 9 to both sides

∵ 5x - 9 + 9 = 2x + 12 + 9

∴ 5x = 2x + 21

→ Subtract 2x from both sides

∵ 5x - 2x = 2x - 2x + 21

∴ 3x = 21

→ Divide both sides by 3 to find x

∵ [tex]\frac{3x}{3}[/tex] = [tex]\frac{21}{3}[/tex]

∴ x = 7

∵ The longest side is 6x - 2

→ Substitute the value of x in its expression to find its length

∴ The longest side = 6(7) - 2 = 42 - 2

∴ The longest side = 40

∴ The length of the longest side is 40

Answer:

y = 1/25

Step-by-step explanation:

Reciprocal of y^(1/2)  : 1/y^(1/2)

1/y^(1/2) = 5

y^(1/2) = 1/5

y = (1/5)^2

Answer:

  10x -30y = 3

Step-by-step explanation:

In general form, you can start by swapping the x- and y-coefficients, negating one of them. To find the new constant for the equation, substitute the values for the given point

  2x -6y = 2(-3.9) -6(-1.4)

  2x -6y = 0.6

Multiplying by 5 will make the numbers be integers, so will put the equation in standard form.

  10x -30y = 3

Answer:

  create widespread damage

Step-by-step explanation:

Hurricanes are tropical storms that generally develop over the Atlantic ocean. The ones of concern in the US are the ones that follow a westward path. They generally gain strength over water, and dissipate over land. They can last several days, though their movement generally means the worst impact in a given area lasts only a matter of hours. (Clean-up may take months or years.)

Hurricanes are one of the largest of storm systems, so can cause widespread damage.

Answer:

At the bottom!

Step-by-step explanation:

Put the two equations into the same standard form:

2x-y=8

-5x+2y=3

Now if you add the two equations up, guess what will happen?

You will "eliminate" the y variable, and only be left with the x variable.

Technically, you will get:

2x-y+2+28-5x+29+2y=8+23

-3x+20y=11

-3x=11

Answer:

Step-by-step explanation:

First you need to find the Slope Intercept form or find the point and slope.

The point is: (-2,3)

and the slope is: 1/2

y - 3 = 1/2(x + 2)

y - 3 = 1/2x + 1

y = 1/2x + 1 + 3

y = 1/2x + 4

Slope intercept form: y = 1/2x + 4
