Sally is 54 years old and her mother is 80, how many years ago was Sally’s mother times her age?
yanalaym [24]

Answer:

<u>41 years ago</u>

Step-by-step explanation:

Let the no. of years ago be x.

Then, the equation we need would be :

=> 80 - x = 3(54 - x)

=> 80 - x = 162 - 3x

=> 2x = 82

=> x = 41

Sally's mother was 3 times her age <u>41 years ago</u>

Checking

=> Sally = 54 - 41 = 13

=> Mom = 80 - 41 = 39

=> 13 x 3 = 39 [∴Verified]

It is estimated that there are 22 deaths for every 10 million people who use airplanes. A company that sells flight insurance pr
Alex Ar [27]

Answer:

The insurance company can make $0.78 for each policy that it sells

Step-by-step explanation:

The loss incurred to the insurance company for each death claim is:

L = \$1-\$100,000=-\$99,999

This event has a 22 in 10 million probability of happening.

The gain for the company for each policy not claimed is:

G= \$1

This event has a 9,999,978 in 10 million probability of happening.

The expected value is:

EV =\$1*\frac{9,999,978}{10,000,000} -\$99,999*\frac{22}{10,000,000} \\EV=\$0.78

Therefore, over the long run, the insurance company can make $0.78 for each policy that it sells.

jeka57 [31]

Answer:

31 pounds

Step-by-step explanation:

From the information given, you can write the following formula to calculate the total cost of sending gifts:

Total cost of sending gifts=2.50+0.85x, where x is the weight of the gifts in pounds

Also, you know that the total cost of sending gifts is $28.85 and you can replace this value and solve for x:

28.85=2.50+0.85x

28.85-2.50=0.85x

26.35=0.85x

x=26.35/0.85

x=31

According to this, the answer is that the gifts weighed 31 pounds.

Points S, L, and P on this grid represent the locations of the school, the library, and the park, respectively.
agasfer [191]

Using the distance formula, the distance from:

School to Library (SL) = 5 units.

Library to Park (LP) = 10 units.

<h3>What is the Distance Formula?</h3>

To calculate the distance between two points on a coordinate plane, the distance formula used is: d = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}.

Given the coordinates of each location as:

  • School, S = (0, 4)
  • Library, L = (4, 1)
  • Park, P = (-4, -5)

Distance from School to Library (SL):

SL = √[(4−0)² + (1−4)²]

SL = √[(4)² + (−3)²]

SL = √25

SL = 5 units

Distance from Library to Park (LP):

LP = √[(4−(−4))² + (1−(−5))²]

LP = √[(8)² + (6)²]

LP = √100

LP = 10 units
