( 9 ÷ 3 ) x 2 = 3 x 2 = 6 marbles ;
Answer: 40
Step-by-step explanation:
The width is 18.
step by step:
1. 2 lengths are 20 which is 20+20 that's 40.
2. 76-40= 36
3. Two widths are 36 cm.
4. so do 36÷2 and that equals 18
23/50 you want the denominator to be 100 so you multiply both by 2
then you get
46/100 or you can divide and get .46
to turn it to a percentage multiple by 100
.46 and 46%
Let the distance of the engineer from the base of the building be x, then
tan 38 = 300/x
x = 300/tan 38 = 300/0.7813 = 383.98
Therefore, the distance from the engineer to the base of the building to the nearest whole foot is 384 feet.
