Convert the mixed numbers into improper fractions...
-19/3 - (-13/3)
The LCD is 9
-19/9 + 13 * 3/9
-19 + 3 * 13/9
20/9
to mixed number is 2 2/9
Answer is A
Answer:
Choice D, 20 inches.
Step-by-step explanation:
The Pythaogorean theorem tells us that the hypotenuse of a triangle, c, can be found by taking: c =
. In this case, a = 3 and b = 4. So:
c = ![\sqrt{a^{2} + b^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7Ba%5E%7B2%7D%20%2B%20b%5E%7B2%7D%20%7D)
c = ![\sqrt{3^{2} + 4^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B3%5E%7B2%7D%20%2B%204%5E%7B2%7D%20%7D)
c = ![\sqrt{9 + 16}](https://tex.z-dn.net/?f=%5Csqrt%7B9%20%2B%2016%7D)
c = ![\sqrt{25}](https://tex.z-dn.net/?f=%5Csqrt%7B25%7D)
c = 5
The sides of a rhombus are all equal. Given that one side is equal to 5, we can simply multiply 5 by 4 to get 20. The perimeter is 20 inches.
Answer:
(a) is 4*C and (B) is 16*C
Answer:
$10.19
Step-by-step explanation:
We are told:
If the mean of 20 prices is $10.39
We have to find the total price
= Mean × number of prices
= 20 × $10.39
= $207.8
5 of the items with a mean of $10.99 are sampled
We would also find the total price
Mean × Number of samples
$10.99 × 5
= $54.95
what is the mean of the other 15 prices?
We find the total prices of the 15 prices
= Total 20 prices - Total of 5 prices
= $207.8 - $54.95
= $152.85
The mean of the other 15 prices
= $152.85/15
= $10.19
