First, convert all fractions to the lowest common denominator: 20

It takes 5/20 of an hour to string bracelets and 2/20 of an hour to string them. Thus, it takes 7/20 of an hour to make one bracelet.

Megan has 5 and 4/20 hours, or 104/20 hours, to make bracelets. Here, we must divide 104/20 hours by 7/20 hours.

Really, it is dividing 104 by 7 since they have the same denominator. 104/7 is 14.86, so she can make 14 whole bracelets in 5 and 1/4 hours.

Step-by-step explanation:

the mean value is the sum of all values divided by how many values there are.

so,

(3 + -5 + 70 + -90 + -13) / 5 = -35/5 = -7

-7° F is the mean temperature of the 5 cities.

karim sent a chain email to 10 of his friends. the number of people who got the email increases by a factor of 1.4 every week. w

Alinara [238K]

Answer:

$P(6) = 10(1.4)^{6} = 75.2$

Step-by-step explanation:

The number of people who receive the email after t weeks can be modeled by the following equation.

$P(t) = P(0)r^{t}$

In which P(0) is the initial number of poeple who received the email and r is the factor.

Karim sent a chain email to 10 of his friends.

This means that $P(0) = 10$

The number of people who got the email increases by a factor of 1.4 every week.

This means that $r = 1.4$

So

$P(t) = 10(1.4)^{t}$

Which expression gives the number of people who got the email after 6 weeks?

$P(6) = 10(1.4)^{6} = 75.2$

15 minutes is

15 minutes * 1 hour/ 60 minutes = 1/4 hour

15 minutes = 1/4 of an hour

10 km/ hour * 1/4 hour = 10/4 km = 2.5 km
