Answer:

3. A. 173.1 Million people.

   B. 26.4 Million people.

Step-by-step explanation:

3. A.

1: 33.89+110.65 = 144.54 Total pop. of Mexico and Canada.

2: 317.64-144.54 = 173.1 million.

Population of the United States minus the total population of Mexico and Canada as found before.

B.

1: Entire Population of Canada plus 30.81 mil for population overage.

33.89+30.81 = 64.7

2: The population of Canada and the defined 2 states minus the given population of one of the states.

64.7-38.3 = 26.4 million people.

Part a is simple just add Mexico and Canada together then take then the formula is US-Mexico and Canada explain my saying how you figured it out

part b is a little more complicated but basically the entire population of Canada is 33.89 million people and the 2 most populated states are 30.81 times greater then the entire population of Canada so first you add that with Canada’s total population and you get 64.7 million now we know the most populated city in the us is 38.3 million so you go 64.7-38.3 and you get 26.4 million for the second most populated state

The value would be 829.89.

The formula we use is 

A=p(1+\frac{r}{n})^{nt},

where A is the total amount, p is the principal, r is the rate expressed as a decimal number, n is the number of times per year the interest is compounded, and t is the number of years. 

We will use 800 for p; 5.25/100 = 0.0525 for r; 365 for n; and (255/365) for t (since it is not a full year):
A=800(1+\frac{0.0525}{365})^{\frac{255}{365}\times365}
\\
\\=800(1+\frac{0.0525}{365})^{255}=829.89

Hi :), im really struggling with this. Just wanted to know if anyone can explain step by step for me please. Id really appreciat
Dvinal [7]

Answer:

314 m²

Step-by-step explanation:

the formula for the surface area of a sphere (As) is

As = 4×pi×r²

the radius r (half of the diameter) is clearly indicated as 5m.

so, As = 4×3.14×5² = 4×3.14×25

I don't even need a calculator for this, as 4×25 = 100

so, As = 100×3.14 = 314

(you know, when multiplying by 10, the decimal point moves right one position. multiply by 100 it moves 2 positions, and so on).

Which equations may be used to determine the 3 consecutive integers whose sum is 127?
s344n2d4d5 [400]

Answer:

a and b.

Step-by-step explanation:

I’ll explain by giving an example.

Let’s say that: a=3;b=4;c=5; => they all are consecutive -> their sum is 12.

=> if we use a) n=3 => 3*n+3=3*3+3=12 => correct.

b) n+(n+1)+(n+2)= 3+4+5=12=> correct.

c)n+2n+3n=3+6+9=18=>incorrect.

d)3n=3*3=9=>incorrect.

HELP PLEASEE!!!!
ss7ja [257]

Answer:

See below ~

Step-by-step explanation:

\textsf {Each of the steps has been reasoned below :}

\implies \textsf {3x - 2 = 4 (Given)}

\implies \textsf {3x = 6 (Addition Property of Equality)}

\implies \textsf {x  = 2 (Division Property of Equality)}

\textsf {In the second step, the property has been applied}\\\textsf {by adding 2 to each side of the equation.}

\textsf {In the third step, the property has been applied by dividing 3 on each side.}
