The answer is 18. 30 divided by 5 is 6. so 3 times 6 is 18.

What is three-fifths of thirty?
well we can look at this way easier by setting them both up with fractions
and since we don't know the numerator (the top number) for thirty we just put x in its place:)
3 x
----- -----
5 30

all we need to do is figure out what we multiplied by 5 to get 30
well lets just divide 30 by 5 ...
30 ÷ 5 = 6
so that means that we multiplied 6 to get 30
in order to get x we do the same to the top number of 3/5 so (3)
3 x 6 = 18 and thats what equals x!
so 3/5s of 30 is 18!
Answer = 18
hope this helps!

Elizabeth wants to use a sheet of fiberboard 27 inches long to create a skateboard ramp with a 17^{\circ}

erma4kov [3.2K]

The height of the ramp above the ground from its highest end is 7.9 inches.

<h3>What is height?</h3>

Height is the vertical distance between two points.

To calculate the height of the ramp above the ground, we use the formula below.

Formula:

h = Lsin∅............. Equation 1

Where:

h = Height of the ramp above the ground
L = Length of the fiberboard
∅ = Angle of elevation from the ground

From the question,

Given:

L = 27 inches
∅ = 17°

Substitute these values into equation 1

h = 27×sin17°
h = 7.89
h ≈ 7.9 inches

Hence, the height of the ramp above the ground is 7.9 inches.

Answer:

Step-by-step explanation:

$2.\\(a-b)^2=a^2-2ab+b^2\\\\x^2-16x=-8\\\\x^2-2(x)(8)=-8\\\\\text{We have}\ 2ab=2(x)(8).\ \text{Therefore}\ b=8.\\\\x^2-2(x)(8)=-8\qquad\text{add}\ 8^2=64\ \text{to both sides}\\\\x^2-2(x)(8)+8^2=-8+64\\\\(x-8)^2=56$

$5.\\2x^2+x-1=2\qquad\text{subtract 2 from both sides}\\\\2x^2+x-3=0\\\\2x^2+3x-2x-3=0\\\\x(2x+3)-1(2x+3)=0\\\\(2x+3)(x-1)=0\iff 2x+3=0\ \vee\ x-1=0\\\\2x+3=0\qquad\text{subtract 3 from both sides}\\2x=-3\qquad\text{divide both sides by 2}\\\boxed{x=-\dfrac{3}{2}}\\\\x-1=0\qquad\text{add 1 to both sides}\\\boxed{x=1}$

$6.\\2x^2-4x=0\qquad\text{divide both sides by 2}\\\\x^2-2x=0\\\\x(x-2)=0\iff x=0\ \vee\ x-2=0\\\\\boxed{x=0}\\\\x-2=0\qquad\text{add 2 to both sides}\\\boxed{x=2}$
