Answer:

a = 5.81 m

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2

where b= 1.5 and c= 6

a^2 +1.5^2 = 6^2

a^2 +2.25 = 36

Subtract 2.25 from each side

a^2 +2.25-2.25 = 36-2.25

a^2 = 33.75

Take the square root of each side

sqrt(a^2) = sqrt(33.75)

a = 5.809475019

We only take the positive root because length must be positive

The surface areas of two similar figures are 4 in2 and 9 in2. If the volume of the larger figure is 216 in3, what is the volume
OverLord2011 [107]
We know that
surface area smaller figure=scale factor²*surface area larger figure
scale factor=√[surface area smaller figure/surface area larger figure]
scale factor=√[4/9]-----> scale factor=2/3
so
volume smaller figure=scale factor³*volume larger figure
volume smaller figure=(2/3)³*216----> (8/27)*216----> 64 in³

the answer is
the volume of the smaller figure is 64 in³

SOLVE THE INEQUALITY -X/7+ 4 ≥ 3X A. x ≤ 14/11 B. x ≤ 2/5 C. x ≤ 2/1 D. x ≥ –1
Mrrafil [7]

You can eliminate fractions by multiplying the whole thing by 7.

... -x +28 ≥ 21x

Now, add x to get all x-terms on the right. Then, divide by the coefficient of x.

... 28 ≥ 22x

... 28/22 ≥ x

This fraction can be reduced, so we have ...

... A. x ≤ 14/11

4(5x-3)=48<br><img src="https://tex.z-dn.net/?f=4%285x%20-%203%29%3D%2048" id="TexFormula1" title="4(5x - 3)= 48" alt="4(5x - 3)

Hello, My Dear Friend!

Solution for 4(5x-3)=48 equation:

<span>Simplifying:
</span>4(5x + -3) = 48<span>

</span><span>Reorder the terms:
</span>4(-3 + 5x) = 48
(-3 * 4 + 5x * 4) = 48
(-12 + 20x) = 48<span>

</span><span>Solving:
</span>-12 + 20x = 48<span>

</span><span>Solving for variable 'x'.
</span>Move all terms containing x to the left, all other terms to the right.
<span>Add '12' to each side of the equation.
</span>-12 + 12 + 20x = 48 + 12<span>

</span>Combine like terms: -12 + 12 = 00 + 20x = 48 + 12
20x = 48 + 12<span>

</span><span>Combine like terms: </span>48 + 12 = 60
20x = 60<span>

</span><span>Divide each side by '20'.
</span>x = 3<span>

</span><span>Simplifying:
</span>x = 3<span>

Therefore, THAT is The Answer!^^^ 

</span>=====> x = 3 <=====
