Answer:

7+(11-4\times 2)=10

Step-by-step explanation:

So, this question involves you to play around with the numbers and the operations a bit. I've come up with a solution, but perhaps there are others as well.

So, we have:

7\text{ } 11\text{ } 4\text{ } 2\text{ } =\text{ } 10

So, what we can do is, for instance, multiply 4 and 2. Subtract that into 11. And then add the difference to 7. Thus:

7+(11-4\times 2)=10

This is a true number sentence. Let's do it to make sure.

First, do the operations inside the parentheses.

Multiplication comes first, so multiply:

7+(11-8)=10

Again, do the parentheses first. Subtract:

7+(3)=10

Now add:

10=10

So our answer is correct :)

Find the center and the radius of this equation by completing the
Colt1911 [192]

Answer:

x^2 +4x +(4/2)^2 +y^2 -20 y +(20/2)^2 +100 = (4/2)^2 +(20/2)^2

And solving we got:

x^2 +4x+ 4 +y^2 +20y +100 +100 = 4 +100

If we subtract 100 from both sides we got:

(x+2)^2 +(y+10)^2 = 4

C= (-2,-10)

r = \sqrt{4}=2

Step-by-step explanation:

For this case we have the following equation given:

x^2 +4x +y^2 -20 y +100=0

We want to find a general expression given by:

(x-h)^2 +(y-k)^2 = r^2

Where the center is (h.k) and the radius is r.

We can begin completing the squares of the equation given and we got:

x^2 +4x +(4/2)^2 +y^2 -20 y +(20/2)^2 +100 = (4/2)^2 +(20/2)^2

And solving we got:

x^2 +4x+ 4 +y^2 +20y +100 +100 = 4 +100

If we subtract 100 from both sides we got:

(x+2)^2 +(y+10)^2 = 4

Then we can conclude that the center is:

C= (-2,-10)

And the radius would be:

r = \sqrt{4}=2

A baseball player reaches first base 3 out of 10 times he is at bat. If the baseball player bats 80 times, about how many times
Amanda [17]

Answer:

I think the answer is 24.

Step-by-step explanation:

I think the answer is 24 because if the baseball player hit the bat and ran the base 3 out of 10 times, then you would multiply 8 x 3 to get 24 out of 80. I don't know if this is the correct answer, this is just what I think it may be.
