two years ago, a car was valued at $24000. This year, the value of the car is $23160. What was the percent decrease in the value of the car

Answer:

9.9%

Step-by-step explanation:

Well, you would just divide the "other" category and the "total" category and then move the decimal over 2 spaces, because you need to multiply by 100 to turn your answer into a percent, so:

[tex]\frac{222}{2222} =0.09999...\\[/tex]

Then once you multiply by 100, or move the decimal to the left 2 spaces, it becomes:

9.9%, which could be rounded to 10% or 9%.

The total cost equation of renting the truck if Emma were to drive mm miles will be

C=2.5m+20

Let,

C=total cost

m=number of miles

the cost function is in the form of

C=am+b

the rental company charges a fee of $2.5 per mile so a=2.5

C=2.5m+b.....................(1)

if Emma were to drive m=2 miles, the total cost would be C=25

25=2.5\c*2+b

25=5+b

25-5=b

20=b

b=20..................put it back in equation 1

C=2.5m+b

Therefore, The total cost equation of renting the truck if Emma were to drive mm miles will be C=2.5m+20

One equivalent ratio is 1:6

To get this ratio, you divide both parts of 2:12 by 2

2/2 = 1

12/2 = 6

So that's why 2:12 is equivalent to 1:6

From here we could multiply both parts by say 3

1*3 = 3

6*3 = 18

Meaning that 1:6 and 2:12 are equivalent to 3:18

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

Two possible answers are 1:6 and 3:18

Answer:

59 degrees (just taking a shot)

Step-by-step explanation:

A six sided polygon should have a total degree total of 720 degrees. 105+142+140+124+88+x=720. When you find x, it should equal 121 degrees. Since x and y are both on a straight line, that line has to be 180 degrees. These are supplementary angles. 180-121 should equal 59.

Answer:

[tex] y = 3x + 2 [/tex]

Step-by-step explanation:

The equation of a linear function in slope-intercept form is: y = mx + b, where, m = slope, and b = y-intercept.

Find slope (m) of the linear function by using any two points, say (3, 11) and (7, 23):

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{23 - 11}{7 - 3} = \frac{12}{4} = 3 [/tex]

To find the y-intercept (b), substitute the value of the corrdinate pair of any of the points represented on the table, and the value of the slope (m) into [tex] y = mx + b [/tex].

Substituting, x = -1, y = -1, m = 3.

[tex] y = mx + b [/tex]

[tex] -1 = 3(-1) + b [/tex]

[tex] -1 = -3 + b [/tex]

Add 3 to both sides

[tex] -1 + 3 = b [/tex]

[tex] 2 = b [/tex]

[tex] b = 2 [/tex]

Substitute m = 3, and b = 2 into the equation of the linear function in slope-intercept form:

[tex] y = mx + b [/tex]

[tex] y = 3x + 2 [/tex]

Answer:

The answer is below

Step-by-step explanation:

Let t represent the time in hour and A(t) represent the amount of accumulating rainfall at time t.

In the first three hours the rain fell at a constant rate of 25mm per

hour, hence:

A(t) = 25t     0 ≤ t ≤ 3

The rain then slows down and remains constant at 75 mm [i.e. 25(3)] for an hour.

The rain increases at a rate of 20t from 4 ≤ t ≤ 6. Hence the piecewise equation is given as:

[tex]A(t)=\left \{ {{25t\ \ \ \ \ \ \ \ \ \ for\ 0\leq\ t\ \leq\ 3} \atop {75\ \ \ \ \ \ \ \ \ \ for\ 0\leq\ t\ \leq\ 6 \atop {75+20(t-4)\ \ for\ 4\ \leq\ t\ \leq\ 6}} } \right. \\\\\left[/tex]

Well, lets break this down.

If you try to add 26 + 26 it would be 52, which is above 48.

So, we have to find how many books he can read in one month.

All we have to do, is divide!

14 = dividend

26 = divisor

Step 1:

Start by setting it up with the divisor 26 on the left side and the dividend 14 on the right side like this:

26⟌14 Then do the rest, ill wait.

once you have a answer, that is how much he reads a month.

now multiply by 48.

Answer:b) $3,846

Step-by-step explanation:

If your third month's revenue is estimated at $5,000, then $3846.15 is  second month's revenue.

percentage, a relative value indicating hundredth parts of any quantity.

Given that  business's revenue will grow at a compounded rate of 30% each month for the first 6 months.

Third month's revenue is estimated at $5,000.

We need to find the second month's revenue.

Let us assume the revenue of second month = x

Compounded rate = 30%

x + 30% of x = 5000

x  + 0.3x = 5000

1.3x = 5000

Divide both sides by 1.3

x = 3846.15

Hence, $3846.15 is  second month's revenue.

Answer:

(a) 0.0000245

(b) 0.000025

Step-by-step explanation:

The complete question is:

Suppose that a computer chip company has just shipped 10,000 computer chips to a computer company. Unfortunately, 50 of the chips are defective. (a) Compute the probability that two randomly selected chips are defective using conditional probability. (b) There are 50 defective chips out of 10,000 shipped. The probability that the first chip randomly selected is defective is  50 /10,000  = 0.005.  Compute the probability that two randomly selected chips are defective under the assumption of independent events.

Solution:

(a)

In this case we need to compute the conditional probability of selecting two defective chips, i.e. the selection of the second defective chip is dependent on the first defective chip.

The probability of selecting the first defective chip is:

[tex]P(1D)=\frac{50}{10000}=0.005[/tex]

Now there are 9999 chips left and 49 defective chips among them.

The probability of selecting the second defective chip is:

[tex]P(2D)=\frac{49}{9999}=0.0049[/tex]

Compute the probability that two randomly selected chips are defective using conditional probability as follows:

P (Two defective chips) [tex]=P(1D)\times P(2D)=0.005\times 0.0049=0.0000245[/tex]

Thus, the answer is 0.0000245.

(b)

Compute the probability that two randomly selected chips are defective under the assumption of independent events as follows:

The above statement implies that the selection was done with replacement.

The probability is:

P (Two defective chips) [tex]=P(1D)\times P(2D)[/tex]

                                      [tex]=\frac{50}{10000}\times \frac{50}{10000}\\\\=0.005\times 0.005\\\\=0.000025[/tex]

Thus, the probability that two randomly selected chips are defective under the assumption of independent events is 0.000025.

On a keyboard, you would write [5, infinity)

The square bracket means "include this value" and a curved parenthesis means "exclude this value". We cannot include infinity as it is not a number, so we always use parenthesis with either infinity.

[tex]y \ge 5[/tex] is the same as [tex]5 \le y[/tex] which is also the same as [tex]5 \le y < \infty[/tex] which may help lead to set up the interval notation answer.

50m = 1cm

? = 8.4cm

50 x 8.4=

420m = 8.4cm

Step-by-step explanation:

firstly we need to find the scale factor

firstly we know that 250m=25000cm

25000/5=5000

so 1:5000 is scale factor.

Now let us find the distance between Sam's school and the library

if they are 8.4 cm apart on map it means that in actual distance they are
