Answer:

about 11.03 million

Step-by-step explanation:

Use the equation I = P(1+r/100)^n - P (I is the compound interest, P is the principle, r is the rate percent, and n is the number of years):

Substitute the values given:

I = 70,000,000(1 + 5/100)^3 - 70,000,000

Use a calculator to solve and you will get ~11.03 million.

For every 11 litres of petrol a car can run for 50 km.
algol [13]

Answer: 50.2 liters

Step-by-step explanation:

11 liters = 50km

Z liters = 228km

To get the value of Z, cross multiply

228 x 11 = Z x 50

2508 = 50z

Divide both sides by 50

2508/50 = 50z/50

50.16 = z

50.16 has two decimal places, so convert to 1 decimal place by approximation

50.16 = 50.2

Thus, 50.2 liters will be enough for 228km

Consider a total of 1,000 people. If it was said that within 1 deviation (of the mean) of all people like MATH 123, how many of
Lesechka [4]

Answer:

680 students

Step-by-step explanation:

The 68 - 95 - 99.7  rule (empirical rule) states that 68% of the population lies within one standard deviation of the mean,  95% of the population lies within two standard deviations and 95% of the population lies within three standard deviations.

Hence since it was said that within 1 deviation (of the mean) of all people like MATH 123, therefore the number of people that like MATH 123 is:

number of people that like MATH 123 = 68% of the population

number of people that like MATH 123 = 0.68 * 1000

number of people that like MATH 123 = 680 students

Using the following triangle, what is the cosine of angle B?
stealth61 [152]

Hello!

To find cosine, use the formula cos = adjacent / hypotenuse.

According to angle B, adjacent of angle B is side A, and the hypotenuse is side c because the hypotenuse is always opposite the right angle.

Therefore, the cosine of angle B is a/c.
