Answer:

v = 5.4

4.9 6.1

6.1 V 26.46

6.1 6.1

v= 4.337704918

v=4.34

the reason u are glancing at 26.46 with no answer is that I cross multiplied every number which gave me 6.1 V and 26.46 ...Don't forget we are focused only on V .The sign that is joining V and 6.1 is MULTIPLICATION sign so we use the opposite which is division .I divided both sides by 6.1 cause we are looking for V which gave me 4.337704918 which looks a little bit odd .So I looked for three significant figures which gave me 4.34 .When u round it to the nearest 100 it stays the same round 4.34 to the nearest hundredth consider the thousandths’ value of 4.34, which is 0 and less than 5. Therefore, the hundredths’ value of 4.34 remains 4.

The original price is c. Then the grocery bill will be: c - 0.05c = 0.95 c. You can also say since the beggining that 5% disscount implies 0.95 factor, which leads to c * 0.95 = 0.95c. Sorry if it’s wrong

The world population at the beginning of 1980 was 4.5 billion. Assuming that the population continued to grow at the rate of app

Answer:

$Q(t) = 4.5(1.013)^{t}$

The world population at the beginning of 2019 will be of 7.45 billion people.

Step-by-step explanation:

The world population can be modeled by the following equation.

$Q(t) = Q(0)(1+r)^{t}$

In which Q(t) is the population in t years after 1980, in billions, Q(0) is the initial population and r is the growth rate.

The world population at the beginning of 1980 was 4.5 billion. Assuming that the population continued to grow at the rate of approximately 1.3%/year.

This means that $Q(0) = 4.5, r = 0.013$

$Q(t) = Q(0)(1+r)^{t}$

$Q(t) = 4.5(1.013)^{t}$

What will the world population be at the beginning of 2019 ?

2019 - 1980 = 39. So this is Q(39).

$Q(t) = 4.5(1.013)^{t}$

$Q(39) = 4.5(1.013)^{39} = 7.45$

The world population at the beginning of 2019 will be of 7.45 billion people.

Math help? 15 Points

Masja [62]

I think the best answer would be F.
When √10 is converted into a decimal it is 3.16, and F is the most close to that.
Hope this helps!
