1. What percent of 600 is 12?
Ainat [17]

Answer:

2%

Step-by-step explanation:

Set up a proportion

x / 100 = 12 / 600

Cross multiply

600x = 1200

Divide both sides by 600

x = 2

I hope this helped and please mark me as brainliest!

The lengths of the bases of a trapezoid are 17 inches and 10 inches. The trapezoid has an area of 189 square inches.
Mamont248 [21]

Answer:

height of this trapezoid is 14 inches.

Step-by-step explanation:

\boxed{Area -of -trapezoid=\frac{a+b}{2} h}

[ Here lengths, a = 17 and b = 10 and area of trapezium given 189 ]

using the formula:

\frac{17+10}{2} *h = 189

\frac{27}{2} h = 189

h = \frac{189*2}{27}

h  =14

In triangle △ABC, ∠ABC=90°, BH is an altitude. Find the missing lengths. AB=4 and BC=3, Find AH, CH and BH.
IRISSAK [1]

Answer:

  • AH = 3.2
  • CH = 1.8
  • BH = 2.4

Step-by-step explanation:  

It can be convenient to compute the length of the hypotenuse of this triangle (AC). The Pythagorean theorem tells you ...

   AC^2 = AB^2 + CB^2

   AC^2 = 4^2 + 3^2 = 16 + 9 = 25

   AC = √25 = 5  

The altitude divides ∆ABC into similar triangles ∆AHB and ∆BHC. The scale factor for ∆AHB is ...

  scale factor ∆ABC to ∆AHB = AB/AC = 4/5 = 0.8  

And the scale factor to ∆BHC is ...  

  scale factor ∆ABC to ∆BHC = BC/AC = 3/5 = 0.6  

Then the side AH is 0.8·AB = 0.8·4 = 3.2

And the side CH is 0.6·BC = 0.6·3 = 1.8  

These two side lengths should add to the length AC = 5, and they do.  

The remaining side BH can be found from either scale factor:    

  BH = AB·0.6 = BC·0.8 = 4·0.6 = 3·0.8 = 2.4

_____  

The sides of interest are ...  

  AH = 3.2

  CH = 1.8

  BH = 2.4
