The ratio of girls to boys at soccer practice is 3:4. If on Saturday there will be a total of 42 players, how many boys will be

Alex777 [14]

Answer:

$Boys = 24$

$Girls = 18$

Step-by-step explanation:

Given

$G:B= 3:4$

$Total = 42$

Required

Determine the number of boys and girls

We have to convert the ratio to fraction;

Number of girls can be calculated as:

$Girls = \frac{G}{G + B} * Total$

$Girls = \frac{3}{3 + 4} * 42$

$Girls = \frac{3}{7} * 42$

$Girls = 3 * 6$

$Girls = 18$

$Boys = Total - Girls$

$Boys = 42 - 18$

$Boys = 24$

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

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

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

Solve the equation log^7b>2

ahrayia [7]

Answer:

b > 12.71

Step-by-step explanation:

Here in this question we have to solve the inequality equation given for b (An unknown variable}

Now, the equation is $(\log b)^{7} > 2$

⇒ $\log b > 2^{\frac{1}{7} }$

We are taking the base of the log here is 10.

So, $10^{(\log b)} > 10^{2^{\frac{1}{7} } }$ {Since $10^{\log x} =x$ and $e^{\ln x} = x$ }

⇒ b > 12.71 (Approximate) (Answer)

What is the product?

Maurinko [17]

Answer:

option C

15 14

-1 9

Step-by-step explanation:

Given in the question a 2x3 and 3x2 matrix

Since, the column of first matrix and row of second matrix is of equal integer, 3, so we can multiply them.

The resultant matrix will be of 2x2

We will use dot product

1(2) + 3(3) + 1(4) 1(-2) + 3(5) + 1(1)

-2(2) + 1(3) + 0(4) -2(-2) + 1(5) + 0(1)
