A dog buried 18 bones in his backyard. On Monday, he dug up 1/2 of his bones. On Tuesday, he dug up another 1/3 of his bones. Ho
Korolek [52]

Answer:

3

Step-by-step explanation:

A dog buried 18 bones

On Monday he dug up 1/2 of the bones

On Tuesday he dug up 1/3 of the bones

= 1/2 × 18

= 9

= 1/3×18

= 6

Therefore the remaining bones still buried in the ground can be calculated as follows

= 9+6

= 15

= 18-15

= 3

Hence 3 bones are still buried in the ground

What are the solutions to the equation |2x-3|+4=17
natta225 [31]

First, let's subtract both sides by 4:

|2x - 3| = 13

We can get two different equations from this:

2x - 3 = 13

and

2x - 3 = -13

So:

2x = 16

2x = -10

x = 8, x = -5

The solution set is {8, -5}

The crime rate of a certain city is increasing by exactly 6% each year. If there were 550
kap26 [50]

Using an exponential function, it is found that the approximate number of crimes in the year of 2016 was of 2502.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the growth rate, as a decimal.

In this problem, there were 550 crimes in the initial year observed, and the growth rate is of 6%, hence the parameters are A(0) = 550, r = 0.06, and the equation is given by:

A(t) = A(0)(1 + r)^t

A(t) = 550(1 + 0.06)^t

A(t) = 550(1.06)^t

2016 is 26 years after 1990, hence:

A(26) = 550(1.06)^{26} \approx 2502

The approximate number of crimes in the year of 2016 was of 2502.
