4 1/6 + (-2 5/6)= kjoijoijoiojijjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj
Bogdan [553]

Answer:

I don’t know about the last part but what I do know id the answer to the equation.

Answer: 1 1/3

Step-by-step explanation:

1. Remove the paranthesis

Removing the paranthesis will make it much easier to solve the equation.

We now have 4 1/6 + -2 5/6.

2. Rearrange the equation

We can’t have two symbols next to each other. We need to cross out one symbol so we can have only one. + and - = -. So let’s keep the "-" symbol.

We now have 4 1/6 - 2 5/6.

3. Solve the remaining equation

Now that we have a proper equation which we can solve, let’s do it.

We should then end up with 1 1/3.

Answer: 1 1/3

9. Wendy noticed that out of 345 cars that passed by her house 56 were
Ilya [14]

Answer:

The answer may be slightly off for a multiple choice question. but for fill in the blank, it should be fine to plur 340.83 as the answer

Step-by-step explanation:

First you find the percentage of tye 1st event

That would be represented by "56 is what percentage of 345?"

to find this, divide 56 by 345, which is .1623

then multiply is by 100 which is 16.23

This says that 16.23 percent of the cars that passed by were SUVS.

Finally, find what 16.23 percent of 2100 would be.

divide 2100 by 100 which is 21. then multiply it by 16.23 which is 340.83.

Find the area of the shaded region of the square.
marishachu [46]

Answer:

42cm^{2}

Step-by-step explanation:

area of the square=14*14(l*w)

                              =196 cm^{2}

radius=14/2

         =7 cm

area of the circle=\pi r^{2}

                           =\frac{22}{7}*7*7

                          =154 cm^{2}

area of the shaded part =196-154

                                        = 42cm^{2}
