Which regions have population ls with 7 as the power of 10
Kryger [21]

From the list, the only region that has a population with seven as the power of ten is Oceania.

<h3>What is the meaning of "the power of ten"?</h3>

In mathematics, large numbers are often expressed as the power of ten. For example 6500 can be expressed as 65 x 10^2 as the exponent (2) indicates the number of zeros.

<h3>What region has a population with seven as the power of ten?</h3>

From the options, the only region that has as a exponent the number seven is Oceania.

Note: This question is incomplete; here is the missing information:

  • In the introduction, we looked at the human populations of different geographic groups. There are about 1 x 10^9 people in Africa, 4.2 x 10^9 in Asia, 7.4 x 10^8 in Northern America, 3.7 x 10^7 in Oceania, and 6 x 10^8 in Latin America and the Caribbean.

Mary takes a sightseeing tour on a helicopter that can fly 450 miles against a 35 mph headwind. In the same amount of time it ca
monitta

Answer:

V = 160mph

Step-by-step explanation:

We need to start from the formula of speed: V=d/t

We have two travels, with and against the wind, both done in the same time.

Clearing t from the formula, we will have: t=d/V2

450miles/V-35mph (speed of the wind is subtracted)

702miles/V+35mph (speed of the wind is subtracted)

Now, we find V:

450miles/V-35mph = 702miles/V+35

450*V+35 = 702*V-35

450V+15,750 = 702V-24,570

702V-450V = 15,750 + 24,570

252V = 40,320

V = 40,320/252

V = 160mph

The graph shows the cost of some taxi journeys<br><br> work out a formula for c in terms of n
Vitek1552 [10]

Answer:

c=\frac{3}{5}(n)+2.5

Step-by-step explanation:

see the attached figure to better understand the problem

Let

c -----> the cost of some taxi journeys

n ----> the number of miles

we know that

The graph is a line

The equation of a line in slope intercept form is

c=m(n)+b

where

m is the slope

b is the c-intercept (value of c when the value of n is equal to zero)

Observing the graph  we have the points

(0,2.5), (5,5.5)

<em>Find the slope</em>

The formula to calculate the slope between two points is equal to

m=\frac{c2-c1}{n2-n1}

substitute the values

m=\frac{5.5-2.5}{5-0}

m=\frac{3}{5}

we have

b=2.5 -----> because the point (0,2.5) is the c-intercept

substitute in the equation of slope-intercept form

c=\frac{3}{5}(n)+2.5
