Answer:
The mistake she made was ; She didn't change the sign when subtracting -3/4 from both sides
She wrote 5/4+3/4 instead of 5/4-3/4
Step-by-step explanation:
Correct solution:
Subtract-3/4 from both sides
Simplify
45x+zy=-c is the anser because of many reasons
Answer:
yes
Step-by-step explanation:
So the circumfrehce of a circle is basically the perimiter of the circle. Let me help with number 1. We need to find the radius. In order to do tuis we divide 6 in half giving us 3. Then we plug in 3 into the circumfrence formula (Pi times the radius multiplied by 2). So it would be 3.14*3*2. The answer for number 1 is 18.85
percent increase = (new -original)/original
= (1200-550)/550
650/550
=1 100/550
1 2/11
1.181818
118.18 percent
to the nearest whole number
118 %
Answer:
10√3m
Step-by-step explanation:
Given :-
- Angle of elevation = 60°
- Distance between man and pole = 60°
We need to find the height of the pole . We are given here base. Therefore using ratio of tan ,
=> tan 60° = p/b
=> √3 = h / 10 m
=> h = 10 m× √3
=> h = 10√3 m
