Answer:
I'm going to use the Pythagoras theorem
1. hypotenus²= base²+height²
h²=80²+18²
h²=6400+324
√h²=√6724
hypotenuse= 82
2. 53²=45²+h²
2809=2025+h²
2809-2025=h²
784=h²
√784=√h²
h=28
3. 40²=b²+24²
1600=b²+576
1600-576=b²
√1024=√b²
b= 32
0<5xb<5 divide all terms by 5
0<xb<1 divide all terms by x
0<b<x
If you meant 5b as in 5*b then:
0<5b<5 divide all terms by 5
0<b<1
b is infinitely many values between 0 and 1.
In the given interval 1 < x < 6, the function is decreasing.
As seen from the graph, the value of function is lower at every next value of x than its previous value. For example value function is lower at x = 2 as compared to x = 1. Likewise the value is lower at x = 3 than x = 1 and x = 2 and this continues till x= 6. Therefore, the function is decreasing.
Another way to look at the problem is see the slope of the function. The line is constantly falling down, which means it is a decreasing function.
Answer : 3 cups of brown sugar to 1 cup of milk
Answer:
18 (or more)
Step-by-step explanation:
Let's start off by creating an inequality:
Let "r" represent one pet rock
5r > 50 + 2r
Let's cancel out the 2r on the right side of the inequality by subtracting 2r from both sides:
5r > 50 + 2r
3r > 50
Now, to isolate r, we must divide both sides by 3:
3r > 50
r > 16.7
(Since we can't sell 16.7 pet rocks, we round up to 17)
r > 17
That means that Rosa has to sell at more than 17 pet rocks (so 18 or more pet rocks) to make profit.
