Answer:

-19/132

Step-by-step explanation:

To add fractions, find the lowest common multiple of the two denominators and multiply accordingly to make both denominators the same. In this case, the lowest common multiple of 11 and 12 is 132, so we need to multiply the first number by 12 and the second by 11. So we get $\frac{36}{132} + (-\frac{55}{132} )$ = $\frac{36-55}{132}$ = $\frac{-19}{32}$ $-\frac{19}{132}$

Mr McDonald has 45 1/2 pounds of grain to feed his farm animals. If each animal eats 3/4 of a pound of feed, how many animals ca

denis23 [38]

Donald can feed 61 animals approximately

Solution:

Given that Donald has $45\frac{1}{2}$ pounds of grain to feed his farm animals

Each animal eats $\frac{3}{4}$ of a pound of feed

To find: number of animals he can feed

From given information,

Total pounds of grains = $45\frac{1}{2} = \frac{2 \times 45 +1}{2} = \frac{91}{2} \text{ pounds }$

One animal feeds = $\frac{3}{4} \text{ pounds }$

number of animals he can feed = Total pounds of grains divided by one animal feeds

$\rightarrow \frac{\frac{91}{2}}{\frac{3}{4}}=\frac{91}{2} \times \frac{4}{3}=\frac{91 \times 2}{3}=\frac{182}{3}=60.66$

Thus he can feed 61 animals approximately

What is the distance between (-2, 6) and (-2, -1)

Sloan [31]

Answer:

7 units

Step-by-step explanation:

(-2,6)=(X1,Y1)

(-2, -1)=(X2,Y2)

now ,

distance=√{(x2-x1)^2+(y2-y1)^2}

=√{(-2+2)^2+(-1-6)^2}

=√49

=7 units
