Answer: 36 3/32
<u>Turn 5 1/4 into an Improper Fraction</u>
Multiply 5*4 and get 20. Now add 1 and get 21.
5 1/4 = 21/4
<u>Turn 2 1/2 into an Improper Fraction</u>
Multiply 2*2 and get 4. Now add 1 and get 5.
2 1/2 = 5/2
<u>Turn 2 3/4 into an Improper Fraction</u>
Multiply 2*4 and get 8. Now add 3 and get 11.
2 3/4 = 11/4
Your New Problem: 21/4×5/2×11/4
<u>Multiply</u>
21/4×5/2×11/4=1155/32
<u>Simplify</u>
1155÷32=36.09375
<u>Trun 36.09375 into a Mixed Number</u>
36.09375 = 36 3/32
Answer:
15 hours.
Step-by-step explanation:
Suppose the time taken to catch Mike is t hours and the distance ran by Mike is x miles then
5.5 = x/ t (Mike) --- ...(1)
6 = (x +7.5 )/ t (Julia ).......(2)
From equation (1):
x = 5.5t ..............(3).
From equation (2):
x + 7.5 = 6t
x = 6t - 7.5............(4).
Eliminating x from equations 3 and 4:
6t - 7.5 = 5.5t
0.5t = 7.5
t = 15 hours.
I'm thinking b
or c is what i think hope i could help ^-^
Answer:
or 2.738
Step-by-step explanation:
Let’s just look at the triangle on the top with the on the top and x on the bottom. (Basically the top half to the equilateral triangle)
There is a small square in the bottom right corner, which indicates that this triangle is a right triangle. This means that we can use the Pythagorean Theorem:
We know that \sqrt{10} is our hypotenuse, and therefore our c in our equation. Let’s say that x=a in our equation. Therefore we are left to find b. However, b is half the length of the side of the original equilateral triangle. An equilateral triangle means that all three sides are the same length. Therefore our side would also be \sqrt{10} units long. However we know that b is half of that value, so b= or
Plugging these values into the equation:
x^2+ (\frac{\sqrt{10} }{2})^{2}=\sqrt{10} ^{2}
This approximately equals 2.738
