Answer:

A. 25/100

B. 1.75 billion people in the world would have no food or shelter. In scientific notation this translates to 1.75 × 10^9

C. 17 percent of the worlds population speaks Chinese, or 1.19 billion people. In scientific notation that translates to 1.19 × 10^9.

D. In a world of 100 people, around 4/100 or 4 percent would live in the U.S.

In 3 × 10^8, that translates to 300 Million out of 7 billion. Exactly 4.28 percent of the worlds population would live in the U.S. Now, translating that percent to a much smaller scale, out of 100 people only 4 people would live in the U.S. You can't have 0.28 percent of a person, so we just estimate it to 4 people.

How many solutions does this linear have y= 5x-1 -15x-3y=3?
musickatia [10]
-15x - 3y = 3

-15x - 3(5x-1) = 3 [input y]
-15x - 15x - 3 = 3 [distribute 3 over 5x and -1]
-30x - 3 = 3 [combine like terms]
-30x = 6 [add 3 to eliminate the negative]
x = \frac{6}{-30} [divide by -30 to get x alone]
x = \frac{1}{-5} [reduce the fraction]

Hopefully this is helpful enough to get you to your answer

What is the distance between (–4, –10) and (–4, –4)?
Gre4nikov [31]

Answer:

6 units

Step-by-step explanation:

(-4 , -10) ; (-4 , -4)

Distance = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}

               = \sqrt{(-4-[-4])^{2}+(-4-[-10])^{2}}\\\\= \sqrt{(-4+4)^{2}+(-4+10)^{2}}\\\\=\sqrt{0+(6)^{2}}\\\\= \sqrt{36}\\\\= 6

A drawing has a scale of 1:40.
uranmaximum [27]

Answer:

300,000 cm^{2} is bigger

Step-by-step explanation:

10 x 40 = 400

18 x 40 = 720

400 x 720 = 288,000 cm^{2} (area of the bedroom)

300,000 cm^{2} is bigger by 12,000 cm^{2} (so the kitchen is bigger)
