<h2><u>☼︎</u><u>Answer:</u></h2>
The cost price of cow = Rs.80
Explanation:
<h2><u>☼︎</u><u>Given :-</u></h2>
- By selling a cow for Rs 144, there is a profit of the same percentage as its cost price.
<h2><u>☼︎</u><u>T</u><u>o Find</u><u>:</u><u>-</u></h2>
<h2 /><h2 /><h2><u>☼︎</u><u>L</u><u>e</u><u>t</u><u>:</u><u>-</u></h2>
- The cost price of cow = Rs.x
<h2><u>☼︎</u><u>Solution :-</u></h2>
<h2><u>Hence: </u></h2>
The cost price of cow =<u>R</u><u>s</u><u>8</u><u>0</u>
Let the measures of three angles be 2x, 9x, 4x
Sum of the angles of a triangle = 180
2x+9x+4x = 180
15x = 180
x = 180/15 = 12
First angle = 2x = 2*12 = 24°
Second angle = 9x = 9*12 = 108°
Third angle = 4x = 4*12 = 48°
I hope it is helpful:D
Step-by-step explanation:
5x - 5° = 40° ( being vertically opposite angles)
5x = 40° + 5°
5x = 45°
x = 45°/ 5
x = 9°
Now
< 1 = 5 * 9° - 5 = 45° - 5° = 40°
Hope it will help :)
<h3>
Answer: D) 198 square meters</h3>
======================================================
Explanation:
Extend the side that's 9.5 meters long out to the left so that you form a trapezoid on top and a rectangle underneath. The side we extended is now 5+9.5 = 14.5 meters long.
Let
- A = area of the trapezoid up top
- B = area of the rectangle underneath
The goal is to find A+B
The trapezoid has the parallel sides of 14.5 and 10 meters. The height of the trapezoid is 28-20 = 8 meters. So we can say
Area of trapezoid = height*(base1+base2)/2
A = h*(b1+b2)/2
A = 8*(14.5+10)/2
A = 98
The rectangle has area of B = length*width = 5*20 = 100 square meters
Therefore,
total area = A+B = 98+100 = 198 square meters.
3. Cost of each box = $84/12 = $7
4. Donation to each charity = $120/4 = $30
