-1 17/20 and -1 8/10 can be compared easily if we give them common denominators. If we multiply the second fraction by 2, both fractions will have a denominator of 20.

8 * 2 = 16
10 * 2 = 20
New fraction: 16/20

-1 17/20 vs. - 1 16/20

-1 16/20 (-1 8/10) is greater. (For negative numbers, you can tell which one is greater by determining which one is closest to zero.)

the number of cakes baked varies directly with the number of hours the caterers work. What is the ratio of cakes baked to hours

aniked [119]

The required ratio of cakes baked to hours worked = 30: 1

Concept:

We know that a ratio is a term in mathematics that signifies how many times one value contains the other.

Given: The number of cakes baked varies directly with the number of hours the caterers work.

Explanation:

From the given graph, it can observe that,

30 cakes are made in 1 hour. ( When we draw a vertical line from x = 1 to the curve, we get y=30 i.e. point is ( 1,30).

The required ratio of cakes baked to hours worked = 30: 1

The projected world population (in billions of people) t years after

MA_775_DIABLO [31]

Answer:

y = 5 e^r * t

Let y be the population in billions and t the value of elapsed years

7 = 5 e^r * t is the equation being used where t = 15

7/5 = e^r * t

ln 7/5 = r * t taking ln of both sides

r = .336 / 15 = .0224

y = 5 e^(.0224 t) is then our equation

Check - suppose you want y at 2020

y = 5 e^(.0224 * 20) would be the equation

y = 5 e^.449 = 7.83 billion - seems to be a reasonable answer
