Explain whether 20/16 is an equivalent ratio to 60/48

1 answer:

6 0

So since 20x3=60 all we have to do is multiply 16 by 3 to find out if it comes out to 48, which in this case it does, so the two ratios are equivalent.

Suppose a city with population 800,000 has been growing at a rate of 5% per year. If this rate continues, find the population of

AleksandrR [38]

Answer:

2,340,208.5 or 2,340,209

Step-by-step explanation:

You could answer this by multiplying the current population of 800,000 by 1.05 (1.05 represents the annual growth rate of population) and do that 22 times. But that would take a while.

we got 1.05 because the formula says that y = a( 1 + r ) power t

for a we will give it 1

so y = 1 ( 1 + 0.05) power t

it will give us 1.05

to do this faster, you would first calculate (1.05)22and then multiply this by 800,000.

So, 800,000 x (1.05)22 = 2,340,208.5 or 2,340,209

Gitta is asked to find the probability of getting all heads on 3 coin tosses. This is a compound event.

DedPeter [7]

1. P(getting all head)= $\frac{n(getting-all-head)}{n(Sample-space)}$

2. Event: getting all head can happen in only one way: HHH

3. n(Sample space) can be calculated by

a. counting, a good ways to organize counting is drawing a tree diagram, CHECK THE PICTURE

or
b. There are 2 possible outcomes each time we throw the dice so 2*2*2=8 is the total number of outcomes, that is the number of the sample space.

4. So finally P(getting all head)= $\frac{1}{8}$

I need the answers for number 9 and 10

Sladkaya [172]

Number 9 is yes, they are congruent.

number 10 is no, they are not congruent because x=3, so segment xy=3(3)+5 which is 14 and segment yz=9(3)/2 which is 13.5
