Find the area of the figure.

8 cm​

Answers

Answer:

The area is [tex]88cm^2[/tex]

Step-by-step explanation:

The formula for the area of a triangle is : [tex]\frac{base*height}{2}[/tex]

To work this out you would first need to work out the area of the square. You can do this by multiplying the length of 8 by the width of 8, this gives you 64. This is because the formula for working out the area is length multiplied by the width.

The next step is to work out the area of a triangle. You can do this by first multiplying the base of 6 by the height of 8, this gives you 48.

The next step is to divide 48 by 2, this gives you 24. this is because the formula is the same for a square, and that a triangle is half of a square with the same dimensions.

The final step is to Add the area of the square which is 64 by the area of the triangle which is 24, this gives you [tex]88cm^2[/tex].

1) Multiply 8 by 8.

[tex]8*8=64cm^2[/tex]

2) Multiply 6 by 8.

[tex]6*8=48cm[/tex]

3) Divide 48 by 2.

[tex]48/2=24cm^2[/tex]

4) Add 64 and 24.

[tex]64+24=88cm^2[/tex]

There are 2,010 Starbucks in California. The population of California is 38.8 million. Which of
the following best represents the Starbucks per capita in Scientific Notation?
1.93 x 104
5.18 x 10-4
51.8
5.18 x 10-5

Answers

Answer:

5.18x10-5 is the correct answer

Step-by-step explanation:

Scientific notations are used to represent relatively large and small numbers.

The population per capita is (d) [tex]5.18 \times 10^{-5}[/tex]

The populations are given as:

[tex]Starbucks = 2010[/tex]

[tex]People = 38.8\ million[/tex]

The population of Starbucks per capita is calculated by dividing the population of Starbucks by the population of the people.

So, we have:

[tex]Per\ Capita = \frac{Starbucks}{People}[/tex]

Substitute known values

[tex]Per\ Capita = \frac{2010}{38.8\ million}[/tex]

Divide

[tex]Per\ Capita = 0.00005180412[/tex]

Approximate

[tex]Per\ Capita = 0.0000518[/tex]

Express as scientific notation

[tex]Per\ Capita = 5.18 \times 10^{-5}[/tex]

Hence, the population per capita is (d) [tex]5.18 \times 10^{-5}[/tex]

Answers

Answer:

Vince began practicing piano at 11:15 P.M

He stopped at 11:35 P.M

=> He practiced in 35 - 15 = 20 mins = 1/3 hour.

=> 1/3 hour means 1/3 circle, the number of degrees the minute hand turned:

N = (1/3) x 360 = 120 deg (1 circle = 360 deg)

Hope this helps!

:)

*Answer*
120 degrees

*Explanation*
A clock is a circle and therefor has 360 degrees. To find how many degrees are in a five minute time span, divide 360 by 12 (the amount of five minute “chunks”)

360/12 = 30

Between 11:15 and 11:35, 20 minutes pass. 20/5 = 4, which means there are 4 five minute intervals. Multiply that by 30, the amount of degrees in every five minute “chunk”

4 x 30 = 120

That means the hand moved 120 degrees.

(Choice D)
D
There are twice as many families where the mother works full time and the father works part time as families where the mother works part time and the father doesn't work.

Answers

Answer:A

Step-by-step explanation: 14% of the mothers work part-time in families where the father works part-time while 7% of the mothers work part-time in families where the father is not working.

Probabilities are used to determine how likely or unlikely an event is. From the 2-column table, it is twice as likely to get a family where the father and the mother work part-time than a family where the father doesn't work, and the mother works part-time.

We use the following representation:

[tex]FF \to[/tex] Father works full-time

[tex]FP \to[/tex] Father works part-time

[tex]FW \to[/tex] Father not working

[tex]MF \to[/tex] Mother works full-time

[tex]MP \to[/tex] Mother works part-time

[tex]MW \to[/tex] Mother not working

Next, we test each of the 4 options, till one of the options is true (see attachment)

Choice A:

The claim in choice A is that:

[tex]P(FP\ and\ MP) = 2 \times P(FW\ and\ MP)[/tex]

From the given table, we have:

[tex]P(FP\ and\ MP) = 0.14[/tex] ---- father works part-time and mother works part-time

[tex]P(FW\ and\ MP) =0.07[/tex] ---- father not working and mother works part-time

Put the above values in the following equation

[tex]P(FP\ and\ MP) = 2 \times P(FW\ and\ MP)[/tex]

[tex]0.14 = 2 \times 0.07[/tex]

[tex]0.14 = 0.14[/tex]

Suppose you deposit $1500 in a savings account that pays interest at an annual rate of 6% if no money is added or withdrawn from the account answer the following questions how much will be in the account in four years how much will be in the account after 16 years how many years will it take for the account to contain $2000 How many years will it take for the account to contain $2500

Answers

Answer:

In 4 years = $1,893.72

In 16 years = $3,810.53

years to contain $2,000 = 4.9371454128

years to contain $2,500 = 8.766692911

Step-by-step explanation:

In 4 years

A = 1,500 (1 + 0.06)^4

  = $1,893.72

In 16 years

A = 1,500 (1 + 0.06)^16

   = $3, 810.53

to find number of years

t = ln (A/P) / ln (1+r)

when A = 2,000

t = ln(2,000/1,500) / ln(1+0.06)

 = 4.9371454128 years

when A = 2,500

t = ln(2,500/1,500) / ln(1+0.06)

 = 8.766692911 years

PS: You can also use log in place of ln

The number of years it will take for the account to contain $2000 is 4.94 years while it will take 8.77 years to contain $2500.

Calculation of future value and the number of years it takes

Let:

PV = Present value = $1,500

r = Interest rate = 6%, or 0.06

n = number of years

FVn = Future value after a certain number of years

Therefore, we have:

The amount that will be in the account in four years can be calculated using the future value (FV) formula as follows:

FV4 = PV * (1 + r)^n = $1,500 * (1 + 0.06)^4 = $1,893.72

Therefore, the amount that will be in the account in four years is $1,893.72.

The amount that will be in the account after 16 years can also be calculated using the future value (FV) formula as follows:

FV16 = PV * (1 + r)^n = $1,500 * (1 + 0.06)^16 = $3,810.53

Therefore, the amount that will be in the account after 16 years is $3,810.53.

The number of years will it take for the account to contain $2000 can be calculated using the following formula:

n = (log(FV/PV)) / (log(1+r)) = (log($2,000/$1,500)) / (log(1+0.06)) = 0.1249387366083 / 0.0253058652647703 = 4.94 years

Therefore, the number of years it will take for the account to contain $2000 is 4.94 years.

The number of years it will take for the account to contain $2500 can be calculated using the following formula:

n = (log(FV/PV)) / (log(1+r)) = (log($2,500/$1,500)) / (log(1+0.06)) = 0.221848749616356 / 0.0253058652647703 = 8.77 years

Therefore, the number of years it will take for the account to contain $2000 is 8.77 years.

8909 ft
3204 ft
8746 ft
3300 ft

Answers

Answer:

The distance from the helicopter to the fire is 8909 feet.

Step-by-step explanation:

Refer the attached figure

The pilot of a helicopter sights a fire at an angle of depression of 11° i.e. [tex]\angle ACB = 11^{\circ}[/tex]

The helicopter's altitude is 1700 feet.i.e.AB = 1700 feet

We are supposed to find the distance from the helicopter to the fire i.e. AC

Using trigonometric ratios

[tex]Sin \theta = Perpendicular}{Hypotenuse}\\\\Sin 11^{\circ}=\frac{AB}{AC}\\\\Sin 11^{\circ}=\frac{1700}{AC}\\\\AC=\frac{1700}{Sin 11^{\circ}}\\\\AC=\frac{1700}{0.1908}\\\\AC=8909.85 feet[/tex]

Hence the distance from the helicopter to the fire is 8909 feet.

A population of adult males had their heights measured. The heights were normally distributed. Approximately
what percentage of the heights, rounded to the nearest whole number, are within one standard deviation of the
mean?

Answers

Answer:

The percentage of the heights that lie within one standard deviation of the mean height is 68%.

Step-by-step explanation:

Here it is given that the heights of adult males of a population are distributed normally.

The Empirical Rule states that in a normal distribution with mean µ and standard deviation σ, nearly all the data will fall within 3 standard deviations of the mean. The empirical rule can be divided into three parts:

68% data falls within 1 standard deviation of the mean.

        That is P (µ - σ ≤ X ≤ µ + σ) = 0.68.

95% data falls within 2 standard deviations of the mean.

        That is P (µ - 2σ ≤ X ≤ µ + 2σ) = 0.95.

99.7% data falls within 3 standard deviations of the mean.

        That is P (µ - 3σ ≤ X ≤ µ + 3σ) = 0.997.

So, the percentage of the heights that lie within one standard deviation of the mean height is 68%.
