<span>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.</span>
A) 6x + 4x - 6 = 24 + 9x
10x - 9x = 24 + 6
x = 30
b) 25 - 4x = 15 - 3x + 10 - x
25 - 4x = 25 - 4x
Infinite Solutions.
c) 4x + 8 = 2x + 7 + 2x - 20
4x - 4x = 7 - 20 - 8
0 = - 22
No solution
The primes factors of 75 are 3 and 5
Answer:
9
Step-by-step explanation:
If you want the number to be divisible by three make sure the sum of all the numbers are divisible by three. Add all the numbers you have to see what they make.
3+4+2+8+4=21
So we just need to find the greatest number we can add to that to have it remain divisible by three. A number divisible by three is 30, and we can add 9 to 21 to make 30. Of course, there are other numbers we could add, but nine is the largest one-digit number that would work. Other smaller numbers include 3 and 6.
3+4+2+8+4+9=30
Now we check to see if our number is divisible by three
342984÷3 = 114328
114328 is a whole number so we know it's divisible.
The acute angle is 40.40 degrees
<h3>How to determine the acute angle?</h3>
The cosine of the angle is given as:
cos(x) = 0.7620
Take the arc cos of both sides

Evaluate the arc cos
x = 40.359
Approximate
x = 40.40
Hence, the acute angle is 40.40 degrees
