Step-by-step explanation:
g/b = 6/5
g = (6/5)b
g + b = 33
---
g + b = 33
(6/5)b + b = 33
(6/5)b + (5/5)b = 33
(11/5)b = 33
---
b = 33(5/11)

100 - 85 = 15%
15% = 6
1% = 0.4
100% = 0.4 x 100 = 40

The Pythagorean theorem is the idea that the sum of the two legs which are both squared is equal to the hypotenuse's length squared.
*<em>look at the image I attached for a better explanation</em>
By looking at the picture, we are missing the leg's length, and by using the Pythagorean theorem, we get the equation
Thus the <u>missing side length is 13.2 cm</u>
Hope that helps!
The problem statement is not clear regarding which money is invested. We will assume it is the 80% of $8750 that is set aside for future education. That amount is
... 0.80 × $8750 = $7000
If x represents the amount invested at 7%, then the total interest earned is
... (7000 -x)×4% + (x)×7% = 420
... 280 +0.03x = 420
... x = 140/0.03 ≈ 4666.67
$4666.67 was invested at 7%.
$2333.33 was invested at 4%.
I think it’s the last one
