Answer:

12 $\frac{5}{6}$

Step-by-step explanation:

$\frac{77}{6}$ = 12 remainder 5

The remainder of 5 forms the numerator of the fractional part of the mixed number while the denominator remains as 6

$\frac{77}{6}$ = 12 $\frac{5}{6}$ ← mixed number

Dr. Irvine saw 130 patients in one week. The ratio of kids to adults that he saw is 3 to 7. If k represents the number of kids a

Vitek1552 [10]

Answer:

The correct answer is

C. k+d=130

7k = 3d

Number of kids Dr. Irvine see in a week is 39.

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Number of patients Dr. Irvine see in a week = 130

Radio of kids to adults = 3:7 or 3/7

Number of Kids = k

Number of adults = d

2. Let's find the equations system that should be set up to find out how many kids Dr. Irvine see

k + d = 130 (Number of patients Dr. Irvine see in a week)

Including the ratio:

7k = 3d

Replacing d:

d = 130 - k

Now substituting:

7k = 3 * (130 - k)

7k = 390 - 3k

10k = 390

k = 390/10

k = 39

The endpoints of a diameter of a circle are A(2,1) and B(5,5). Find the area of the circle in terms of pi.

Tcecarenko [31]

Answer:

The area of the circle is $A=6.25\pi\ units^{2}$

Step-by-step explanation:

step 1

Find the diameter of circle

we know that

The diameter of the circle is equal to the distance AB

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$AB=\sqrt{(5-1)^{2}+(5-2)^{2}}$

$AB=\sqrt{(4)^{2}+(3)^{2}}$

$AB=\sqrt{25}$

$AB=5\ units$

therefore

the diameter of the circle is

$D=5\ units$

step 2

Find the area of the circle

The area of the circle is equal to

$A=\pi r^{2}$

$r=5/2=2.5\ units$ ----> the radius is half the diameter

substitute

$A=\pi (2.5)^{2}$

$A=6.25\pi\ units^{2}$
