Answer:
Height of the sail is 15 inches.
Step-by-step explanation:
Given:
Area of the fabric =
Base of the sail = 8 in.
We need to find the height of the sail.
Solution:
Let the height of the sail be 'h'.
Now we know that;
Area of Triangle is given by half time base multiplied by the height.
framing in equation form we get;
Dividing both side by 4 we get;
Hence height of the sail is 15 inches.
<u>1 and 2/3 tasks</u>
a) A robot can complete 7 tasks in 3/5 hours.
This means ;
7 tasks = 3/5 hours
1 task = ?
perform cross- multiplication as;
{1*3/5} /7
3/35 hours
b)
3/5 hours = 1 task
1 hour = ?
{1*1} / 3/5
1 / 3/5
1 * 5/3
(4 x 1.39) + (3 x 0.89) = x
5.56 + 2.67 = x
x = 8.23
