There is a total of 63 bikes if the ratio of blue to black bikes is 4 to 5 how many are blue

DedPeter [7]

Since the given ratio is blue:black is 4:5
4+5=9

4/9= 0.44 ~ 44%
5/9= 0.56 ~ 56%

Since there are a total of 63 bikes and 44% of these bikes are blue we just multiply 44% with the total number of bikes.

Solution:
1. 0.44 x 63 = 28
2. 0.56 x 63 = 35

Conclusively, there are 28 bikes that are colored blue.

A state map has a circle-shaped compass. If the radius of the compass is 15 millimeters, what is the approximate area of the com

GuDViN [60]

The area of a circle by definition is given by:
A = pi * r ^ 2
Where,
r: radius
Substituting the values we have:
A = (3.14) * (15) ^ 2
A = 706.5 mm ^ 2
Answer:
The approximate area of the compass is:
A = 706.5 mm ^ 2

A Square has the vertices at (-2,6) (6,1) (1,-7) (-7,-2). At what point do the diagonals of the square intercect

DerKrebs [107]

Answer: At point ( $-\frac{1}{2},-\frac{1}{2}$ )

Step-by-step explanation: Diagonal is a line uniting two opposite points. In a square, the diagonals intersect in a 90° and bisect each other, i.e., divides each diagonal into two segments of the same length.

In other words, the diagonals of a square meet at their midpoint, which is found as the following:

(x,y) = $(\frac{x_{1}+x_{2}}{2} ,\frac{y_{1}+y_{2}}{2})$
