Answer:
153.86 square feet
Step-by-step explanation:
The formula for the area of a circle is :
To work this out you would simply multiply pi by the radius of 7 squared, this gives you 153.86. This is because if you were to substitute the values into the formula you would also get the same answer.
1) Multiply pi by 7 squared.
In this question pi is as 3.14
If you would like to solve the inequation G/4 - 8 <= - 10, you can calculate this using the following steps:
G/4 - 8 <= - 10
G/4 <= - 10 + 8
G/4 <= - 2 /*4
G <= - 2 * 4
G <= - 8
The correct result would be G <= - 8.
46 emails were gotten in 2 weeks.
1 email was gotten in (2/46) week
115 emails will take: (2/46)* 115 = 5
115 emails will be gotten in 5 weeks.
I hope this helps.
Answer:
The number of Television at the beginning was 90
The number of video cassette recorders at the beginning was 89
Step-by-step explanation:
Selling Price of 1 Television =$360.
Selling Price of 1 video cassette recorders for $270.
Let the number of Television at the beginning=x
Let the number of video cassette recorders at the beginning =y
Opening Stock =$56,430.
Therefore:
It sells three quarters of the televisions and one third of the video cassette recorders for a total of $32,310.
270x+90y=32310
We then solve the two equations to obtain x and y.
- 360x+270y=$56,430. (Multiply by 270)
- 270x+90y=32310 (Multiply by 360)
97200x+72900y=15236100
97200x+32400y=11631600
Subtract
40500y=3604500
y=89
Substitute y=89 into 270x+90y=32310 to obtain x
270x+90(89)=32310
270x=32310-8010=24300
x=90
Therefore:
The number of Television at the beginning was 90
The number of video cassette recorders at the beginning was 89
