or: -0.86 total days

or: -20.66 total hours

or: -1,239.75 total minutes

or: -74,385.00 total seconds

Using an exponential function, it is found that the projected growth rate is of 4.5%.

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + k)^t[/tex]

In which:

In this problem:

We use the information given to solve for k.

[tex]A(t) = A(0)(1 + k)^t[/tex]

[tex]37.1 = 23.9(1 + k)^{10}[/tex]

[tex](1 + k)^{10} = \frac{37.1}{23.9}[/tex]

[tex]\sqrt[10]{(1 + k)^{10}} = \sqrt[10]{\frac{37.1}{23.9}}[/tex]

[tex]1 + k = \left(\frac{37.1}{23.9}\right)^{\frac{1}{10}}[/tex]

[tex]1 + k = 1.045[/tex]

[tex]k = 0.045[/tex]

The growth rate was of 4.5%.

Answer:

x=12

Step-by-step explanation:

overline AD = overline AB + overline BD

overline AD =10+10

overline AD =20

tan( angle BAC)= overline BC/overline AB

tan( angle BAC)= 6/10

angle BAC=30.964°

angle DAE= angle BAC

angle DAE=30.964°

tan( angle DAE)= overline DE/AD

tan (30.964 degrees) = x/20

x = 12

Answer:

89/56 (first option)

Step-by-step explanation:

The LCD (or Least Common Denominator) of all the fractions is 840.

5/7 (the smallest number) is equivalent to 600/840, while 7/8 (the largest number) is equivalent to 735/840.

600/840 + 735/840 = 1335/840, which reduces to 89/56.

=============================================================

Explanation:

It helps to make a table of all possible outcomes. Refer to the diagram below. Along the top we have the outcomes 1,2,3,4. Along the left side we have 2,3,4,5. Each row & column header is then added to form the corresponding inner cell. For example, in the top left corner we have 1+2 = 3.

There are 4 outcomes of spinner A and 4 outcomes of spinner B. This means we have 4*4 = 16 outcomes overall. Out of those 16 sums, we have the odd results {3,5,7,9} show up 1+3+3+1 = 8 times.

The probability we want is therefore 8/16 = 1/2. This is expected since half of the values of {1,2,3,4} are odd, and the same applies to {2,3,4,5}. So we should expect half of the sums to be odd as well.

Put another way: for any row or column, you'll find that the pattern is odd/even/odd/even or even/odd/even/odd. This shows that 50% of any row or column represents an odd number. This idea extends out to the entire table overall.

Answer:

1/2.

Step-by-step explanation:

There are 2 odd and 2 even numbers on each spinner.

Odd totals will come from an odd number from the first spinner and an even number from the second spinner, or vice versa.

So the number of possibilities  of an odd total = 2 * (2 * 2) = 8.

The total number of all possible outcomes = 4*4 = 16.

So the required probability is 8/16 = 1/2.

Answer:

10 inches

Step-by-step explanation:

we know that 2 inches is equal to 50 miles, so:

2x = 50

x= 25, which means that 1 inch is 25 miles.

250/25 = 10, which means that it would take 10 inches to be equal to 250 miles.

describe the set member of 1,8,27,64​

All these numbers are the cube of consecutive numbers ,the cube of 1 is 1, the cube of 2 is 8 ,3 is 27 ,4 is 64 and so the next number which is 5 , it's cube will be 125 and so the series will be 1, 8, 27, 64, 125 ,216 and so on

Answer:As most maths problems, you don’t have to convert it immediately in numbers to solve it.

It’s obvious that John works twice as fast as Tom to paint the same surface. It means that if they work simultaneously, at any time John will always have painted twice as much surface as Tom. So if they plan it properly and they end the painting of the room at the same time, John will have painted twice as much surface as Tom.

There is only one possibility : if Tom painted 1/3 of the room and John painted 2/3.

Now, if Tom painted 1/3 of the room it probably took him 1/3 of the time needed to paint the entire room, or 12/3=4 hours. It also works for John : 6*2/3=4 hours
