State if the triangle is congruent
melisa1 [442]

Answer:

Step-by-step explanation:

m∠ JHI + m∠GHJ = 180    { linear pair}

m∠JHI + 90 = 180

m∠JHI = 180 -90 = 90

In ΔGHJ and ΔJHI,

          GJ = IJ   { given}

         JH = JH    {common}

 m∠ JHI = m∠GHJ  { above proved}

ΔGHJ  ≅ ΔJHI     { Angle Side Side congruence}

Lia has a red ribbon that is 2 1/12 inches long she has a blue ribbon that is 4 time as many inches as long how many inches long
Rom4ik [11]

Answer:

8 1/3 inches

Step-by-step explanation:

Length of the ribbon = 2 1/12 inches

Blue ribbon is 4 time as many inches as long as red

Length of the blue ribbon = 4 * 2 1/12

Length of the blue ribbon = 4 * 25/12

Length of the blue ribbon = 100/12

Length of the blue ribbon= 25/3

Length of the blue ribbon = 8 1/3 inches

Hence the blue ribbon is 8 1/3 inches long

Composite volcanoes are known for their beautiful, distinctive cone shape. A composite volcano called Mayon in the Philippines h
Grace [21]

Answer: 77.283km^{2}

Step-by-step explanation:

The formula for the lateral area of a cone L.A is:

L.A=\pi r h

Where:

r=10km is the radius of the circular base of the cone

As we know its diameter d=20km, its radius is r=\frac{d}{2}=10km

h=2.46km is the height of the cone

L.A=\pi (10km)(2.46km)

L.A=77.283km^{2} This is the lateral area of the volcano with the shape of a cone

A suit is on sale for $154. If the original price of the suit was $440, what percent was discounted for the sale
Zina [86]
440(100-p)/100=154

440(100-p)=15400

44000-440p=15400

-440p=-28600

p=65%

So the price was discounted 65% off the original price.
