7 0

Answer:

18 ducks

Step-by-step explanation:

add the parts of the ratio 7 + 6 = 13

divide the total by 13 to find one part of the ratio

$\frac{39}{13}$ = 3 ← 1 part of the ratio

7 parts = 7 × 3 = 21 ← number of swans

6 parts = 6 × 3 = 18 ← number of ducks

Part I: Describe the center and radius of the circle.

trasher [3.6K]

Answer:

Center (2,4) , radius=3, h=2 v=4 & r=3

Step-by-step explanation:

Ok so in order to find the center of the circle, use the graph (like you can see that the x is 2,if you count down from 5 to the left. the y is 4,because it's below 5 in the y pole).So the center is (2,4)

Now, in order to find the length of the radius, you need to do the following:

Take the center point (2,4) and the point where the circle ends (2,1) . Because radius is a straight, you can substract the y values of the two points : 4-1=3

As you can see in the equation, the h symbolizes the x of the center point and the v symbolizes the y.The r is the radius that we already found(3)

So it's shouldn't be a problem now to find the equation of the circle,simply replace the values with their numbers:

(x-2)^2 + (y-4)^2 = 9

The center of a sphere is HURRY ON A TIMER

omeli [17]

Answer:

Center of the Sphere is a fixed point in its interior which is equidistant from each point on sphere. Option 1 is not right because it says center is line segment. Option 3 is right as it says it is fixed and equidistant from point of surface.

Step-by-step explanation:

1 The center of a sphere is

2 a line segment from the center point to the surface of the sphere.

3 a fixed point equidistant from all points on the surface of the sphere.

4 a three-dimensional circle in which all points are equidistant from a fixed point.

5 the same as the base of the sphere

Businesses deposit large sums of money into bank accounts. Imagine an account with 10 million

Nikitich [7]

Answer:

The account will earn in one year the amount of $10,512,000

Step-by-step explanation:

Given as :

The principal in the account = $10,000,000

The rate of interest = 5.12% at simple interest

The time period = 1 years

Let The amount that account earn after 1 year = $A

<u>From Simple interest method</u>

Simple interest = S.I = $\dfrac{\textrm principal\times \textrm rate\times \textrm time}{100}$

or, S.I = $\dfrac{\textrm 10,000,000\times \textrm 5.12\times \textrm 1}{100}$

or, S.I = $\dfrac{51200000}{100}$

or, S.I = $512,000

So, Simple interest = S.I = $512,000

Now, Amount = Principal + Interest

I.e A = $10,000,000 + $512,000

Or, A = $10,512,000

So, Amount = A = $10,512,000

Hence The account will earn in one year the amount of $10,512,000 Answer
