The answer is 11. The radius of the circle is 11 because in the equation (x-h)^2=(y-k)^2=r^2, we take the square root of the constant term on the outside to get the radius. The equation given can be rewritten as (x+5)^2+(y-10)^2=(11)^2.

The standard form of a circle:
(x-h)^2+(y-k)^2=r^2
Where:
(h; k) - the coordinates of a centerr - the radius
We have: (x+5)^2+(y-10)^2=121
therefore
(-5;\ 10) - the center
r^2=121\to r=\sqrt{121}\to r=11 - the radius
Answer: 11

What is 25 percent of 148​
valentina_108 [34]

Answer: 37

Step-by-step explanation: To find 25% of 148, first write 25% as a decimal by moving the decimal point two places to the left to get .25 which is the decimal equivalent to 25%.

Next, the word "of" means multiply so we will need to multiply.

(.25) (148) = 37

Therefore, 37 is 25% of 148.

James uses the Distributive Property to find how many cans of paint are in the art supply closet. There are 5 boxes in the close
julia-pushkina [17]

Answer:

70 cans of paint

Step-by-step explanation:

We are told in the question that:

1 box holds = 14 cans of paint

5 boxes =

Cross Multiplying

5 boxes will hold = 5 × 14

= 70 cans of paint

This question, requires that we use Distributive property

Distributive property states that: when 2 factors or numbers are multiplied together the result will be the same as splitting on of the numbers(factors) into two distinct numbers, multiplying both number by the other factor, and adding together both products.

Applying the definition above to solve the question, we would be splitting the number of boxes which is 5 into 2 distinct number = 2 and 3

As , 2 + 3 = 5

Hence, we have:

14 × 5 = 14( 2 + 3)

70 = 28 + 42

70 cans of paint = 70 cans of paint.

The numbers of cans of paint that are in the art supply closet is 70 cans of paint

Check the picture below.

\textit{vertex of a vertical parabola, using coefficients} \\\\ y=\stackrel{\stackrel{a}{\downarrow }}{-16}x^2\stackrel{\stackrel{b}{\downarrow }}{+160}x\stackrel{\stackrel{c}{\downarrow }}{+20} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right)

\left(-\cfrac{ 160}{2(-16)}~~~~ ,~~~~ 20-\cfrac{ (160)^2}{4(-16)}\right) \implies \left( - \cfrac{ 160 }{ -32 }~~,~~20 - \cfrac{ 25600 }{ -64 } \right) \\\\\\ \left( 5 ~~~~ ,~~~~ 20 +400 \right)\implies (\stackrel{seconds}{5}~~,~~\stackrel{feet}{420})
