The United States has 435 members of the House of Representatives in Congress. If there are 325.7 million people in the country,

drek231 [11]

Answer:

$1.36\times 10^{-6}:1$

Step-by-step explanation:

We have been given that the United States has 435 members of the House of Representatives in Congress. There are 325.7 million people in the country.

To find the ratio of members to the people, we will find compare both numbers.

1 million equals 1,000,000.

$\text{325.7 million}=325.7\times 1,000,000$

$\text{325.7 million}=3257,000,000$

Ratio of members to the people:

435: 3257,000,000

$0.0000013355848941:1$

$1.3355848941\times 10^{-6}:1$

$1.36\times 10^{-6}:1$

Therefore, our required ratio would be $1.36\times 10^{-6}$ members per person.

What is the value of x in the equation x – y = 30, when y = 15?

oee [108]

<span>x - y = 30 therefore if y is 15 x - 15 = 30 so it follows that x = 30 + 15 which means x has a value of 45x - y = 30 therefore if y is 15 x - 15 = 30 so it follows that x = 30 + 15 which means x has a value of 45</span>

Help I can't solve it right.

djyliett [7]

Answer:

x = 7

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are in proportion , that is

$\frac{LM}{QR}$ = $\frac{KN}{PS}$ , substitute values

$\frac{4x+4}{48}$ = $\frac{7x-9}{60}$ ( cross- multiply )

48(7x - 9) = 60(4x + 4) ← divide both sides by 48

7x - 9 = 1.25(4x + 4) ← distribute parenthesis

7x - 9 = 5x + 5 ( subtract 5x from both sides )

2x - 9 = 5 ( add 9 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

Write an equation in slope-intercept form for the line that passes through (0,1) and (1,3)

Lana71 [14]

Answer:

y= 2x+1

Step-by-step explanation:

Points:

(0,1) and (1,3)

Form of the line:

y=mx+b, m- the slope, b- y-intercept

Finding the slope:

m= (y2-y1)/(x2-x1)
m=(3-1)/(1-0)= 2/1= 2

Line is now:

y= 2x+b

Using one of the given points to find out the value of b:

1=2*0+b
b=1

So the equation for the line is:

y= 2x+1
