If the length of each side of an equilateral triangle were increased by 50 percent, what would be the percent increase in the ar

Shkiper50 [21]

Answer:

<u><em>The area increase by 225%</em></u>

<em><u>Step-by-step explanation: </u></em>

<em><u>attachment of a triangle</u></em>

<em><u>The area of a triangle equilateral is calculated with the next formula:</u></em>

<em><u>A= $\frac{a*h}{2}$ </u></em>

<em><u> $h^{2} +(\frac{a}{2})^{2}$ = $a^{2}$ </u></em>

<em><u> $h^{2} = a^{2} - \frac{a^{2} }{4}$ = $\frac{a^{2} }{4}$ *3</u></em>

<em><u>h= $\sqrt{\frac{a^{2}*3 }{4} }$ </u></em>

<em><u>h= $\frac{\sqrt{3}*a }{2}$ </u></em>

<em><u>replacing in the A equation:</u></em>

<em><u>A= $\frac{a*\sqrt{3}*a }{2*2}$ </u></em>

<em><u>A= $\frac{\sqrt{3}*a^{2} }{4}$ </u></em>

<em><u>Now each side increse by 50% ⇒ a=1.5a</u></em>

<em><u>A= $\frac{\sqrt{3}*(1.5a)^{2} }{4}$ </u></em>

<em><u>A= $\frac{\sqrt{3}*a^{2}* 2.25 }{4}$ </u></em>

<em><u>A=2.25 * $\frac{\sqrt{3}*a^{2} }{4}$ </u></em>

<em><u>It means that the area incrase by 225%</u></em>

What is the order of rotational symmetry for the figure

Naily [24]

Answer:

Order of symmetry = 1

Step-by-step explanation:

First of all we will define rotational symmetry.

Rotational symmetry is when a shape looks the same after some rotation or less than one rotation.

The order of rotational symmetry is how many times it matches the original shape during the rotation.

The given shape, when rotated will only have the shape like original shape after one complete rotation so the order of symmetry is one ..

Next-door neighbors Bob and Jim use hoses from both houses to fill Bob's swimming pool. They know that it takes 22 h using both

FrozenT [24]

Answer:

correct answer: Bob's hose required alone 33 hours and Jim's hose required alone 66 hours

Step-by-step explanation:

Given:

Bob's hose time = 50% of Jim's hose time ⇒

⇒ Jim's hose time = 2 · Bob's hose time

Let be x Bob's hose time and 2x Jim's hose time

The following equation will solve the problem:

1/x + 1/ 2x = 1/22

The common denominator for both fractions is 2x, so we will multiply the first fraction by the number 2 and get:

2/2x + 1/2x = 1/22 ⇒ 3/2x = 1/22 ⇒ x = 3 · 22 / 2 ⇒ x = 3 · 11 = 33 hours

Bob's hose time x = 33 hours and

Jim's hose time 2x = 66 hours

God is with you!!!
