Answer: 36 are red
Step-by-step explanation:
3 out of every 5
5*12 = 60
so do 3*12 which = 36
36/60
For 1:
Use pythagorean theorem because of the radius tangent theorem(point of contact = 90 degrees)
12 is the hypotenuse (the right angle points at the hypotenuse)
Therefore:
(9)^2 + (x)^2 = (12)^2
81 + x^2 = 144
Subtract 81 from both sides of the equation
x^2 = 63
Square root both sides to get rid of square on x and isolate the variable
The square root of 63 = 7.93 (roughly)
Let x be the price of Tanya's item. Tanya spent 5x, because she bought 5 of them.
The cost of Tony's item is x-1.75, because the price is 1.75 less than Tanya's. He spent 6(x-1.75), because he bought 6 of them.
They spent the same amount of money, so we have
So, Tanya's item costs 10.5, and Tony's item costs 8.75.
In fact, we have
