Given that triangle GHI and JKL are similar, the measure of side JK to the nearest tenth is 43.7

<h3>What is the measure of side JK?</h3>

Similar triangles are triangles that have the same shape and are proportional, but their sizes may vary.

Given that;

  • Triangle GHI is similar triangle JKL
  • Side IH = 13
  • Side GH = 9.8
  • Side LK = 58
  • Side JK = ?

Since the triangle are similar;

IH/GH = LK/JK

Plug in the given values and solve for side JK.

13/9.8 = 58/JK

Cross multiply

13 × JK = 58 × 9.8

13 × JK = 568.4

JK = 568.4 / 13

JK = 43.7

Given that triangle GHI and JKL are similar, the measure of side JK to the nearest tenth is 43.7.

Three days,
1 1/4 = 5/4  
1/2= 2/4
2/4+1/4= 3/4 the first day
5/4-3/4= 2/4 
2/4 = 1/4 and 1/4 = two days

To work out the area in m² of material required for a pair of curtains, a seamstress squares the height of the window in m and a
Kisachek [45]

Answer:

a. Area = 1.94m²

b. Area = (p² + 0.5)m²

c. Height = 1.5m

Step-by-step explanation:

Given

<em>Let H represents Height and A represents Area</em>

<em>From the first and second statements, we have that:</em>

<em></em>A = H^2 + 0.5<em></em>

<em></em>

<em>a. Calculating Area When Height = 1.2</em>

<em></em>A = H^2 + 0.5<em></em>

<em>Substitute 1.2 for H</em>

<em></em>A = 1.2^2 + 0.5<em></em>

<em></em>A = 1.44 + 0.5<em></em>

<em></em>A = 1.94<em></em>

<em></em>

Hence, the area is 1.94m²

<em></em>

<em>b. Calculating Area When Height = p</em>

<em></em>A = H^2 + 0.5<em></em>

<em>Substitute p for H</em>

<em></em>A = p^2 + 0.5<em></em>

<em></em>

Hence, the area is (p² + 0.5)m²

<em></em>

c. <em>Calculating Height When Area = 2.75m</em>²

<em></em>A = H^2 + 0.5<em></em>

<em>Substitute 2.75 for A</em>

<em></em>2.75 = H^2 + 0.5<em></em>

<em>Subtract 0.5 from both sides</em>

<em></em>2.75 - 0.5 = H^2 + 0.5 - 0.5<em></em>

<em></em>2.75 - 0.5 = H^2<em></em>

<em></em>2.25 = H^2<em></em>

<em></em>

<em>Take Square Root of both sides</em>

<em></em>\sqrt{2.25} = \sqrt{H^2}<em></em>

<em></em>\sqrt{2.25} = H<em></em>

<em></em>1.5 = H<em></em>

<em></em>H = 1.5<em></em>

<em></em>

Hence, the height is 1.5m

How long does it take $450 to double at simple interest rate of 14%
umka2103 [35]
A = P(1+rt)
A (Future) = 450(2) = 900
P (Principal) = 450
R (Rate) = 14% = .14
T (Time) = Unknown

Create the equation:
900=450(1+.14t)

Distribute the 450:
900=450 + 450(.14t)

Multiply the 450(.14t)
900=450 + 63t

Subtract the 450:
450 = 63t

Divide by 63:
t=7.142857

Answer:
It will take 7.1 years.
