Answer: 430 cm²
Step-by-step explanation:
1) Front x Back= 15 x 7 x 2= 210 (We do time 2 because there are two of the same shapes ex. there are two squares that are both 16 ft so just do 16 x 2)
2) Right x Left= 7 x 5 x 2 = 70
3) Top x Bottom= 15 x 5 x2 = 150
4) Add. 150 + 210 + 70 = 430 cm²
Hope that helped! :)
Given parameters:
Perimeter of the court = 100m
Unknown:
Dimensions = ?
Solution:
let the width = w
Length is 16m more;
Length = w + 16
Perimeter = 2(L + w)
100 = 2 (w + 16 + w)
100 = 2(2w + 16)
100 = 4w + 32
4w = 100 -32
4w = 68
w = 17
So, length = w + 16 = 17 + 16 = 33m
The dimensions of the court are length 33m and width 17m
To find out which angles are coterminal, add and subtract 360 degrees from 50 degrees, so
your answer is 310, 670, -410, -770
Answer:
7.5 days
Step-by-step explanation:
A working = 10 days
AB working = 4 days
AB = 4 --> 10B = 4
/10 /10
B = .4
AB = 3
A(.4) = 3
/.4 /.4
A working alone = 7 .5 days
<em>*pretty much solve for B and then equal AB to the amount of days the worked together before B left, 3 days, then it gives you the amount of time A must work to finish the house alone*</em>
