The <em><u>correct answers</u></em> are:
KL = 2*JL; JK = (√3)JL; and JK = ((√3)/2)KL
Explanation:
This is a 30-60-90 right triangle. This type of triangle has a special relationship among the sides. Let the smallest side, across from the 30° angle, be t. This means JL = t.
The hypotenuse of the triangle is two times the length of the smallest side; this means that KL = 2t, which means that KL = 2*JL.
The side of the triangle opposite the 60° angle will be the "medium sized" side; it is equal to √3 times the smallest side, or √3t; this gives us that JK = √3t = (√3)JL.
Comparing JK to KL, we have
The t on top and bottom cancel out, leaving us with the ratio (√3)/2. This means that JK = ((√3)/2)KL.
Divide by 10 to find how many tens he needs.
1200/10 = 120
Answer: He needs 120 tens
Complete question :
Jeremiah plans on building a 5 meter long garden walkway that is paved with square stones that measure " 5/6 meter on each side. There will be no spaces between the stones. How many stones will be needed to complete the garden walkway?
Answer:
12
Step-by-step explanation:
Given that:
Length of square block to be used = 5/6 meters
Length of garden. Walkway = 5 m
Since length of walkway is the same on both sides, then the Total length = 5m + 5m = 10 meters
Number of square stones required :
Total length of walkway / side length of stones to be used
= 10 meters ÷ (5/6) meters
= 10 * 6/5
= 60 / 5
= 12 stones
Answer:
6 hours
Step-by-step explanation:
She already has $55, so we can subtract that from $395.
395-55 = 340
So now we can figure out how many hours she needs to work. We'll set up the problem like this, where x = the number of hours needed:
60x = 340
Divide each side by 60: x = 5.666(repeating decimal)
Rounding up to the nearest hour, Marie needs to work 6 hours.
Answer:
0.16 Acres per sheep
Step-by-step explanation:
Since there are 40 acres spread upon 250 sheep, you would divide the acres by the number of sheep. Make an equation
40/250 =....
