One possible solution for the system of inequalities is given as follows:

13 dimes and 2 nickels.

<h3>How to obtain the system of inequalities?</h3>

The first step in obtaining the system of inequalities is identifying the variables, which are given as follows:

  • Variable x: number of dimes that Tallulah has.
  • Variable y: number of nickels that Tallulah has.

Tallulah has at most 18 coins, hence:

x + y ≤ 18.

A nickel is worth 5 cents = $0.05, while a dime is worth 10 cents = $0.1, and Tallulah has at least $1.20 combined, hence:

0.1x + 0.05y ≥ 1.20.

The solution is given by the shaded region on the image given at the end of the answer, and one possible solution is given as follows:

x = 13, y = 2.

Which means that she has 13 dimes and 2 nickels.

Answer:

d. 0.133

Step-by-step explanation:

-Standard error is  calculated using the formula:

E=\frac{\sigma}{\sqrt{n}}\\\\\sigma-=standard \ deviation\\n=sample \ size

#We substitute the given values in the formula to solve for E:

E=\frac{\sigma}{\sqrt{n}}\\\\=\frac{1.2}{\sqrt{81}}\\\\=0.133

Hence, the standard error is 0.133 and the correct option is d

Driving to your friend's house, you travel at an average rate of 35 miles per hour. On your
Mamont248 [21]

Answer:

14 miles.

Step-by-step explanation:

Let the distance traveled from home to destination = x miles.

Speed while going to friend's house = 35 miles per hour.

Speed while coming back = 40 miles per hour.

Total Time taken for the journey = 45 minutes = 0.75 hours.

Let the time taken while going to friend's house = y hours.

Therefore, the time taken while going to friend's house = (0.75 - y) hours.

To find x and y, model the speeds of both the journeys.

Speed while going to friend's house = Distance/Time.

35 = x/y.

x = 35y (Equation 1).

Speed while coming back = Distance/Time.

40 = x/(0.75 - y).

x = 40(0.75 - y) (Equation 2).

Since x = x, therefore:

35y = 30 - 40y.

75y = 30.

y = 30/75.

y = 0.4 hours.

Put y = 0.4 hours in Equation 1:

x = 35y.

x = 35(0.4).

x = 14.

Therefore, the distance between my friend's house and my house is 14 miles!!!
