The radius of a circle is 2 kilometers. What is the area of a sector bounded by a 36° arc?

answer has to be in SIMPLEST form

Answer:

Both m^2 and cm^2 are given below. Take your pick.

Step-by-step explanation:

Area = L * W

L = 1.57 m * 100 cm / 1 meter = 157 cm

W = 45 cm

Area = 157 cm * 45 cm = 7065 cm^2

In meters, the width would be 45 cm * 1 m / 100 cm = 0.45 m

Area = L * W

L = 1.57 m

W = 0.45 M

Area = 1.57 * 0.45

Area = 0.7065 m^2

Step-by-step explanation:

Total fruit purée = 2 1/4 L

purée for One movie = 3/8 L

which expression can be used to find the number of movies you can make

Number of movies you can make = Total fruit purée ÷ purée for One movie

= 2 1/4 ÷ 3/8

= 9/4 ÷ 3/8

= 9/4 × 8/3

= (9*8) / (4*3)

= 72 ÷ 12

= 6

Number of movies you can make = 6

Answer:

Each student gets 1.75 ft of ribbon

Step-by-step explanation:

r × 4 = 7

First, divide the given factor by itself in order to get the variable by itself.

4 ÷ 4

Next, divide the product by the given factor bc what you do to the left, you must do to other side.

7 ÷ 4

Last, right down your new equation and find you solution.

New Equation: r = 1.75

Answer:

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ 3, 4 ] , then

f(b) = f(4) = - 1 ← from table

f(a) = f(3) = - 5 ← from table , then

average rate of change = [tex]\frac{-1-(-5)}{4-3}[/tex] = [tex]\frac{-1+5}{1}[/tex] = 4

Answer:

the time taken by Mrs Brown to catch up is 18.75 hours

Step-by-step explanation:

Given;

average speed of Mr Brown = 75 mph

average speed of Mrs Brown, = 85 mph

time first traveled by Mr Brown = 2.5 hours

The distance traveled by Mr Brown before Mrs Brown start her own Journey;

D = speed  x time

D = 75 mph x 2.5 h

D = 187.5 miles

Let the time taken by Mrs Brown to catch up = t

(85 - 75)t = 187.5

10t = 187.5

t = 18.75 hours

Check:

after 18.75 hours:  Mrs Brown will travel ⇒ 18.75 x 85 = 1593.75 miles

after (2.5 h + 18.75h) : Mr Brown will travel ⇒ 21.25 x 75 = 1593.75 miles

Answer: 25

Step-by-step explanation: The number that is added to both sides is the number that is needed to create a perfect square trinomial.

The question is, what is that number?

Well, it comes from a formula. The number that is added to both sides always comes from half the coefficient of the middle term squared.

So half of -10 squared or -5 squared which is 25.

So 25 is added to both sides.

Answer:

4 × x

Step-by-step explanation:

Variable x = a number

Product = multiplication

Set up an equation:

4 × x

Answer:

115

Step-by-step explanation:

Given :

Mean of intelligence score = 100

Standard deviation of intelligence score = 15

Since both are perfectly correlated,

The Zscore ON SAT = +1.0

Using the standard normal interpretation, Xcore on SAT of +1.0 means 1 standard deviation to the right

This means :

Mean + 1 standard deviation

100 + 1*15

= 115

We could use the Zscore formula directly too:

Zscore = (x - mean) / standard deviation

Zscore = +1 ; x = score

Hence, we have

1 = (x - 100) / 15

1 * 15 = x - 100

15 = x- 100

x = 15 + 100

x = 115

Answer:

48

Step-by-step explanation:

Volume of triangular prism = Base Area × length of prism

Base area = ½*base*height

base = c = 3 cm

height = b = 4 cm

Base area = ½*3*4 = 6 cm²

Length of prism = d = 8 cm

Therefore,

Volume = 6 × 8 = 48 cm³

Answer:

I believe it is C, 14. sorry if its wrong! ^^"

Step-by-step explanation:

Answer:

D. 16

Step-by-step explanation:

the scale factor says it all

PR = 15 PQ = 8 AC = 30

meaning each side length from the bigger triangle is twice as larger than the other triangle

Answer:

18 units²

Step-by-step explanation:

Solve for height:

4² + x² = 5²

16 + x² = 25

9 = x²

x = 3

Solve for area:

Formula = (base1+base2)h / 2

(4 + 8)* 3 ÷ 2

12 * 3 ÷ 2

36 / 2 = 18

Answer:

154 inches tall.

Step-by-step explanation:

In this scenario, the sun's angle is the same for both objects. Since we have three values and 1 variable (height of the pole) we can use the Rule of Three to solve this. In this, we simply multiply the diagonal values of the ratios and divide by the third value to get the value of the variable like so...

55 in.  <=====>  70 in.

x  <=========>  196 in.

(55 * 196) / 70 = x

10,780 / 70 = x

154 in. = x

Finally, we can see that the flagpole is 154 inches tall.

Answer:

n = 116.2 ≈ 117  

Option E) 117 is the correct answer.

Step-by-step explanation:

Given the data in the question;

Exceed = 0.1

{ 1 - 0.1 = 0.9 }

normal table value at 0.9 = - 1.285

Normal table;

hence

( y - 400 ) / 40 = -1.285

y - 400  = -51.4

y = 400 - 51.4

y = 348.6

so,

348.6 = ∈(y) = ∈[ ⁿ∑[tex]_{i=1[/tex] X[tex]_i[/tex] ]

348.6 = n.∈( X[tex]_i[/tex]  )

we substitute

348.6 = n × 3

n = 348.6 / 3

n = 116.2 ≈ 117  { roundup since we talking of number of cars i.e sample size }

Option E) 117 is the correct answer.

Answer:

P’ is (2,-2)

Step-by-step explanation:

For us to get the appropriate translation, we have to add 9 to the x-coordinate value and subtract 3 from the y-coordinate value

so, we have the transformation as follows;

(-7+9, 1-3)

= (2,-2)

Answer:

$900.9

Step-by-step explanation:

Find the final price of a $849.99

laptop with 6% sales tax.

Given data

Price= $849.99

Tax = 6%

Let us find the amount of the tax

=6/100*849.99

=0.06*849.99

=$50.9994

Now the final price is

=50.9994+849.99

=$900.9

Answer:

315881.53

Step-by-step explanation:

We first need to figure out how long it takes for the money to triple

let x= number of years it takes for the money to tirple

[tex]3=(1+\frac{.04}{365})^{365x}\\log_{1.0001}3=365x\\10025.38644=365x\\27.46681216=x[/tex]

Now plug that value into the continously compounding formula

[tex]80000*e^{27.4668*.05}=315881.5314[/tex]

Which rounds to

315881.53

Answer:
