Answer:
21.62m
Step-by-step explanation:
first draw the the pipe
second you need know wich is the angle between the pipe and the corner
β=Tan^-1(6/9)=33.7
find the components using tow triangles
a=9/cos(33.7)=10.81m
b=6/sen(33.7)=10.81m
finally sum the leghts
L=10.81+10.81=21.62mm
attached procedure
61*40=60*40+1*40=2400+40=2440.
Therefore [] is 4
In order to find the unit rate of acres per day, or in other words, how many acres can they plant in one day, you must divide 5/8, the number of acres planted, by 4/5, the number of days it took to plant. When you divide the two fractions, first set up an expression:
5/8<span>÷4/5
Then, to make things simpler, turn the division expression into a multiplication statement so that you have 5/8*5/4. Then multiply straight across and you get your answer as 25/32. This means that the workers can plant 25/32 acres per day.</span>
Each roast beef cost $4 and each vegetarian sandwich cost $2.5
Let x represent the cost of each roast beef and let y represent the cost of each vegetarian sandwich.
Bhargav buys five roast beef and three vegetarian sandwiches and the order costs $27.50. This can be represented by the equation:
5x + 3y = 27.50 (1)
Bhargav buys 2 roast beef and 6 vegetarian sandwiches and the order costs $23.00. This can be represented by the equation:
2x + 6y = 23.00 (2)
To find x and y, we have to solve equation 1 and 2 simultaneously. Multiply equation 1 by 2 and subtract equation 2 from the result:
8x = 32
x = 4
Put x = 4 in equation 2
2(4) + 6y = 23.00
6y = 15
y = 2.5
Therefore each roast beef cost $4 and each vegetarian sandwich cost $2.5
