3 1/2 - 4 2/5<br> how do i do this?
Nadusha1986 [10]

Answer:

Ok so first you would have to turn them into improper fractions which is

3 \frac{1}{2\\} = \frac{7}{2} and 4 \frac{2}{5} = \frac{22}{5}

So now that you have made them both improper fractions you have to find common denominators.

To find common denominators you must multiply both the numerator and the denominator by the same thing. Since your oposing fraction has a denominator of 5 you can know that a even number wont go in an odd number so take \frac{22}{5} and mutiply both numbers by 2 and get \frac{44}{10}. Then mutiply both numbers in \frac{7}{2} by 5 to get a common denominator.

\frac{35}{10}

\frac{35}{10} - \frac{44}{10} =35 - 44 = -9 so your answer is -\frac{9}{10}

For each container of tea, McKenzie uses 16 tea bags and 3 cups of sugar. If McKenzie uses 64 tea bags, how many cups of sugar w
cestrela7 [59]
So tis is a ratio  16 is to 3 or 16:3
if use 64 tea bags then how many cups of sugar so
turn 16:3 into fraction
16:3=16/3 or 3/16, it doesn't matter
then you want to find 64:x or 64/x or x/64

we know that 16/3=64/x because it tis an equivalent ratio
so 16/3=64/x
multiply both sdies by (3 times x)
16 times x times 3/3=64 times 3 times x/x
16 times x=64 times 3
16x=192
divide both sdies by 16
x=12
theanswer is 12 cups of sugar

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The period of a periodic function is 8 s

From the question:

8n = 30

n = 30/8

n = 3.75 cycles

Thus, the number of cycles of the periodic function is 3.75 cycles if the  period of a periodic function is 8 s option (G) 3.75 is correct.
