In △ABC, CM is the median to AB and side BC is 12 cm long. There is a point P∈CM and a line AP intersecting BC at point Q. Find the lengths of segments CQ and BQ, if P divides CM into CP:PM=1:2.

Answers

Answer 1

Answer:

CQ = 2.4 cmBQ = 9.6 cm

Step-by-step explanation:

This development is ugly, but it works.

Let area ΔABC = 6a. Then area ΔAMC = 3a, and area ΔAPC = a. Similarly, area ΔBMC = 3a, and area ΔBPC = a.

Let area ΔCPQ = x. Then ...

... area ΔACQ = area ΔAPC + area ΔCPQ

... area ΔACQ = a + x

Define k such that BQ : CQ = k : 1. Then ...

... area ΔBPQ + area ΔCPQ = area ΔBPC

... kx + x = a = (k +1)x

The division of BC into parts of ratio k : 1 means ...

... area ΔABQ = k × area ΔACQ

... area ΔABQ + area ΔACQ = area ΔABC

... k × area ΔACQ + area ΔACQ = area ΔABC

... (k +1)(x +a) = 6a . . . . . . . area ΔACQ = x+a

... (k +1)x +(k +1)a = 6a . . . . . distributive property

... a + (k +1)a = 6a

... k +2 = 6 . . . . . . . . . . . . . . . divide by a, simplify

... k = 4

Now, we know BQ : CQ = 4 : 1, so ...

... BQ = 4/5 × 12 cm = 9.6 cm

... CQ = 1/5 × 12 cm = 2.4 cm

In ABC, CM Is The Median To AB And Side BC Is 12 Cm Long. There Is A Point PCM And A Line AP Intersecting

How much water must be evaporated from 20 gallons of a 10% salt solution in order to obtain a 20% salt solution?

Answers

Answer:

8 gallons have to be evaporated to have a 20% salt solution.


hope this helped :)

Step-by-step explanation:

.10*20=2 gallons of salt.

That leaves 18 gallons of water.


.2x=2


x=2/.2


x=10 gallons after evaporation.


18-10=8

Final answer:

To obtain a 20% salt solution from a 10% salt solution, 20 gallons of water must be evaporated.

Explanation:

To obtain a 20% salt solution from a 10% salt solution, the amount of water that needs to be evaporated can be calculated using a proportion. First, convert the percentages to decimals by dividing them by 100. Let x be the amount of water to be evaporated. The amount of salt in the initial solution is 10% of 20 gallons, or 0.10 * 20 = 2 gallons. The resulting solution will have 20% salt in a total volume of 20 - x gallons. Set up a proportion:

(2 gallons)/(20 gallons) = (0.20 * (20 - x) gallons)/(20 - x gallons)

Cross multiply and solve for x:

2(20 - x) = 0.20(20 - x)

Now solve the equation:

40 - 2x = 4 - 0.20x

2x - 0.20x = 40 - 4

1.8x = 36

x = 36/1.8

x = 20

Therefore, 20 gallons of water must be evaporated from the initial 20-gallon solution to obtain a 20% salt solution.

As a promotion, a clothing store draws the name of one of its customers each week. The prize is a coupon for the store. If the winner is not present at the drawing, he or she cannot claim the prize, and the amount of the coupon increases for the following week's drawing. The function f(x) = 20 (1.2)^x gives the amount of the coupon in dollars after x weeks of the prize going unclaimed. {{ x is the exponent on (1.2). }}

(A) What is the percent increase each week?

(B) What is the original amount of the coupon? (the initial value)

(C) What is the amount of the coupon after 2 weeks of the prize going unclaimed?

(D) After how many weeks of the prize going unclaimed will the amount of the coupon be greater than $100?

Answers

The given formula is f(x) = 20(1.2)^x

The formula is the starting amount multiplied by 1 + the percentage raised to the number of weeks.


A) the percent increase is 20% ( 1.2 in the formula is 1 +20% as a decimal)

B) the original amount is $20

C) for 2 weeks, replace x with 2 and solve:

20(1.2)^2

20(1.44) = $28.80

After 2 weeks the coupon is $28.80

D)  To solve for the number of weeks (x) set the equation equal to $100:

100 = 20(1.2)^x

Divide both sides by 20:

5 = 1.2^x

Take the natural logarithm of both sides:

ln(5) = ln(1.2^x)

Use the logarithm rule to remove the exponent:

ln(5) = x ln(1.2)

Divide both sides by ln(1.2)

x = ln(5) / ln(1.2)

Divide:

X = 8.83

At 8.83 weeks the coupon would be $100, so after 9 weeks the coupon would be greater than $100

The answer is 9 weeks.

Which equation has the same solution as this equation? x^2-16x+12=0

Answers

Final answer:

Another equation that shares the same solutions as x²-16x+12=0 is 2x² - 32x + 24 = 0. This equation is the initial equation multiplied by 2 and thus would produce the same solutions when the quadratic formula is applied.

Explanation:

The equation given is a quadratic equation, which is in the form ax²+bx+c = 0. The solutions of a quadratic equation are given by the formula: -b ± √b² - 4ac / 2a. This formula can be used to find the solutions of any other quadratic equation. For the given equation, x²-16x+12=0, the values of a, b, and c are 1, -16, and 12 respectively. So, another equation with the same solutions could be 2x² - 32x + 24 = 0. This equation has the same solutions because it's simply the initial equation multiplied by 2, so this doesn't change the results of the quadratic formula.

Step-by-step explanation:


Answer:

Step-by-step explanation:

Let q, p, k represent the ages of Quinn, Parker, and Karl, respectively.

... q = 2k . . . . . . Quinn is twice as old as Karl

... q = p+4 . . . . . Quinn is 4 years older than parker

We can use the first two equations to find Karl's age in terms of Parker's.

... p+4 = q = 2k

... (p+4)/2 = k

Now, we can substitute for q and k in the last equation.

... (p+4) +p +(p+4)/2 = 21

... 5/2p +6 = 21 . . . . . . collect terms

... p = (2/5)(21 -6) . . . . subtract 6, multiply by 2/5

... p = 6 . . . . . . Parker is 6 years old

The premium is 16.53% of that, so is ...

... 0.1653 × 2575 = 425.65

Answer:

The insurance company charges an annual premium of $425.65 .

Option (d) is correct .

Step-by-step explanation:

As given

Ralph wants to purchase a renters insurance policy for his new apartment.

His insurance company charges an annual premium of 16.53% of the approximate value of the items he owns and is keeping in his apartment.

Total amount of the items he owns and is keeping in his apartment = TV cost + VCR cost + DVD Player cost + Stereo cost + Sofa cost + Entertainment centre cost  +  Microwave cost + Coffee Maker cost +  Computer cost + Bicycle cost  +  Coin Collection cost  + Pictures/Posters cost

Putting all the values in the above

Total amount of the items he owns and is keeping in his apartment = $150 + $60 +$100 + $ 80 + $200 + $100 + $40 + $20 + $850 + $ 200 + $ 600 + $ 175

Total amount of the items he owns and is keeping in his apartment = $ 2575

16.53 % is written in the decimal form .

[tex]= \frac{16.53}{100}[/tex]

= 0.1653

Insurance company charges an annual premium = 0.1653 × Total amount of the items he owns and is keeping in his apartment .

                                                                                   = 0.1653 × 2575

                                                                                   = $ 425.65 (Approx)

Therefore the insurance company charges an annual premium of $425.65 .

Step-by-step explanation:

The chip is 14  nanometers

14 * .000000001

.000000014

Move the decimal 8 places to the right, because we need 1 number in front of the decimal for scientific notation.  The exponent will be -8 because  we moved it 8 places to the right

1.4 × 10^-8

Final answer:

The thickness of the silicon chip in scientific notation is 1.4 x 10^-8 m.

Explanation:

To express the thickness of the silicon chip in scientific notation, we need to convert the given thickness of 14 nanometers to meters.

Since 1 nanometer (nm) is equal to 0.000000001 meters, we can convert 14 nanometers to meters by multiplying it by the conversion factor:

14 nm x 0.000000001 m/nm = 0.000000014 m

Now, we can express the thickness of the chip in scientific notation:

0.000000014 m = 1.4 x 10-8 m

Step-by-step explanation:

We know that Eric is [tex]6\frac{1}{6}[/tex] feet tall while his brother is [tex]5\frac{3}{4}[/tex] feet tall. We are supposed to find out how many feet is Eric taller than his brother.

So basically we have to find the difference between the height of the two brothers.

First, let's just change the mixed numbers to improper fractions:

[tex]6\frac{1}{6}[/tex] = [tex]\frac{37}{6}[/tex]

[tex]5\frac{3}{4}[/tex]=  [tex]\frac{23}{4}[/tex]

Now taking their difference:

[tex]=\frac{37}{6} -\frac{23}{4}\\\\=\frac{148-138}{24}\\\\=\frac{10}{24}\\\\=\frac{5}{12}[/tex]

Therefore, Eric is 5/12 feet taller than his brother.

Select Linear or Nonlinear for each function. Function Linear Nonlinear y=5x+1 y=23 y=1−2x2

Answers

The correct classification for each function is as follows:

1. [tex]\( y = 5x + 1 \)[/tex] - Linear

2. [tex]\( y = 23 \)[/tex] - Linear

3. [tex]\( y = 1 - 2x^2 \)[/tex]- Nonlinear

A linear function is one that can be written in the form [tex]\( y = mx + b \)[/tex], where [tex]\( m \)[/tex] and [tex]\( b \)[/tex] are constants, and [tex]\( x \)[/tex] is the independent variable. The graph of a linear function is a straight line.

1. For the function [tex]\( y = 5x + 1 \)[/tex], we can see that it is already in the form of a linear equation with [tex]\( m = 5 \)[/tex] and [tex]\( b = 1 \)[/tex]. Therefore, this function is linear.

2. The function [tex]\( y = 23 \)[/tex] is a constant function. Although it does not have an [tex]\( x \)[/tex] term, it can still be considered linear because it can be written as [tex]\( y = 0x + 23 \)[/tex], where the slope [tex]\( m = 0 \)[/tex] and the y-intercept [tex]\( b = 23 \)[/tex]. The graph of this function is a horizontal line, which is a special case of a linear function.

3. The function [tex]\( y = 1 - 2x^2 \)[/tex] contains an [tex]\( x^2 \)[/tex] term, which makes it a quadratic function. Quadratic functions are nonlinear because their graphs are parabolas, not straight lines. The presence of the [tex]\( x^2 \)[/tex] term means that the rate of change of [tex]\( y \)[/tex] with respect to [tex]\( x \)[/tex] is not constant, which is a key characteristic of nonlinear functions. Therefore, this function is nonlinear.

Ming is given the following function and asked to find b. f(x)=15(b)x If f(4) = 1215, what is one possible value of b?

Answers

Step-by-step explanation:

f(x) = 15(b)x

f(4) = 1215

15(b)4 = 1215

(15)(4)b = 1215

60b = 1215

60b / 60 =  1215 / 60

b = 20.25

Check the answer

15 * 20.25 * 4 = 1215

Answer:

3

Step-by-step explanation:

if you did this on prepworks its 3.

1215=15(b)4  

121515=(b)4

81=b4

92=b4

(32)2=b4

34=b4

b = ±3

A local garden club had 14 members with a mean age of 34. Then two new members joined. One was 24 years old, and the other was 36 years old. How did the mean age change after they joined? The mean age increased. The mean age decreased. It isn't possible to determine how the mean would change. The mean age stayed the same.

Answers

Answer:

The mean age decreased.

Step-by-step explanation:

I find it convenient to look at the additions with respect to the current mean age.

The current total age is 14×34. We have added members with ages (34 -10) and (34 +2), so the new total age is ...

... (34×14) + (34 -10) + (34 +2) = (16×34) - 8

Dividing this total by 16 will give the new mean age. (We already know it is less than 34.)

... ((16×34) -8)/16 = 34 - 1/2 = 33 1/2 . . . new mean age; a decrease

Answer:

2968.30 cm cube.

Step-by-step explanation:

Given is a cone and top of it is a hemisphere of radius 9 cm.

Cone has height as 17 and radius same 9 cm.

We have to find the volume of the compound shape

We find that the volume would be the sum of that of hemisphere of radius 9 cm and cone of height 17, and radius 9 cm.

Volume of compound shape = volume of cone+Volume of hemisphere

= [tex]\frac{1}{3} \pi r^{2} h+\frac{2}{3} \pi r^{3}[/tex]

substitute for h and r in the equation

Required volume =

[tex][tex]\frac{1}{3}\pi  r^{2} (h+2r) = \frac{1}{3}\pi  9^{2} (17+2(9))\\= 1441.99+1526.31\\=2968.30[/tex][/tex]

So answer is 2968.30 cm cube.
