An electric toothbrush costs $56, including a 40% price markup. What was the cost for the store to purchase the electric toothbr

Anna007 [38]

The cost for the store to purchase the electric toothbrush will be;

⇒ $22.40

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

The cost of electric toothbrush = $56

And, The price of markup = 40%

Now,

Since, The cost of electric toothbrush = $56

And, The price of markup = 40%

So, The cost for the store to purchase the electric toothbrush is;

= (40% of $56)

= (40/100 x 56)

= $22.4

Thus, The cost for the store to purchase the electric toothbrush will be;

⇒ $22.40

Answer:

(a) AC = 12.565 m

(b) bearing of C from A is 90°

(c) BT = 9.373 m

Step-by-step explanation:

(a) extend North line down & perpendicular to AC.

Call that perpendicular intersection "P".

∠BAC = 90° - 53° = 37°

cos 37° = AP/15

0.7986 = AP/15

AP = 11.979 m

∠PNC = 180° - 161° = 19°

∠BCP = 90° - 19° = 71°

18 cm = 0.18 m (red flag note: 18 cm looks very out of scale for the picture)

cos 71° = CP/0.18

0.3256 = CP/0.18

CP = 0.586 m

AC = 11.979 + 0.586 = 12.565 m

(b) The bearing to C from A is 90°

(c) tan 58° = 15/x

1.6003 = 15/x

x = 9.373 m

The population in 1995 was 11,211 people. The annual increase of the population is 8.18%. What is the population of cypress in 2

Sergeeva-Olga [200]

Answer:

The population in 2019 will be of 73989.79

Step-by-step explanation:

The growth of the population is growing in a compounded manner, so to solve this problem we can use a compounded interest formula, as shown below:

M = C*(1 + r)^t

Where M is the final population, C is the initial population, r is the growth rate and t is the time elapsed. In this case we have a initial population in 1995 and we want to know the population in 2019, so the time elapsed is 24 years. We can solve the question by applying the provided data as shown below:

M = 11211*(1 + 0.0818)^24

M = 11211*(1.0818)^24 = 73989.79

What is the vertex of each function's graph?

seraphim [82]

Function B increases at a faster rate. The rate of change for A is 1. The rate of change for B is 1.5.

In order to find the rate of change for each so that we can compare, we need to use the following formula.

Change = (y2 - y1)/(x2 - x1)

In which (x1, y1) is the original point (x = 2) and (x2, y2) is the second point (x = 3). So, let's use the equation for each set of points.

FUNCTION A

Change = (y2 - y1)/(x2 - x1)

Change = (0 - -1)/(3 - 2)

Change = 1/1

Change = 1

FUNCTION B

Change = (y2 - y1)/(x2 - x1)

Change = (0 - -1.5)/(3-2)

Change = 1.5/1

Change = 1.5
