Answer:

EM = 73 m

Step-by-step explanation:

Using the right triangle MOE

with legs MO = 48. EO = 55 and hypotenuse EM

Applying Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

EM² = 48² + 55² = 2304 + 3025 = 5329 ( take the square root of both sides )

EM = [tex]\sqrt{5329}[/tex] = 73

Answer:

1130.4 cubic meters

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo.

My answer:

The composite solid has two cones:

=> the volume of the big cone is:

V = (1/3)π[tex]r^{2}[/tex]·h = (1/3)*3.14*[tex]6^{2}[/tex]*18 = 678.24 cubic meters

=> the volume of the small cone is:

V = (1/3)π[tex]r^{2}[/tex]·h = (1/3)*3.14*[tex]6^{2}[/tex]*12 = 452.16 cubic meters

=> the volume of the composite solid :

= 678.24 + 452.16

=1130.4 cubic meters

Answer:

1 quarter, 1 dime, and 4 nickels

Step-by-step explanation:

First you subtract the 18 cents that were found in the pocket from the total amount of 73 cents to get the total amount of the 6 other coins:

73-18=55.

So the total amount of the 6 coins equals 55 cents.

The quarter = 25 cents

The dime = 10 cents

The 4 nickels =  5 + 5 + 5 + 5 = 20

1 quarter, 1 dime, and 4 nickels add up to the necessary total of 6 coins and when you add up the total cents of the quarter, dime, and nickels, 25 + 10 + 20 it comes to the sum of 55, which is how much the 6 coins are worth in total.

So therefore, the answer is 1 quarter, 1 dime, and 4 nickels.

Answer: b. Damarias median sale is $52

Step-by-step explanation:

Hi, the correct option is b. Damarias median sale is $52.

If we rank the sales order from lowest to highest

28 46 48 48 52 52 59 60 71 192

Since 52 is the middle value, it's the median, because 4 sales are above it and 4 sales are below it.

Answer:

Answer:

38.3

Step-by-step explanation:

Since the patio is a square all of the sides have to be equal.

153/4=38.25

Rounded to the nearest tenth the answer is 38.3

Each side of the patio is approximately 38.3 feet long.

Given:

Given that the height of the cone is 12 ft.

The volume of the cone is 90 ft³

We need to determine the area of the base of the cone.

Area of the base of the cone:

The area of the base of the cone can be determined using the formula,

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

where the base area is [tex]A=\pi r^2[/tex]

Substituting the value of A in the above formula, we get,

[tex]V=\frac{1}{3}A h[/tex]

Substituting V = 90 and h = 12, we get;

[tex]90=\frac{1}{3}A (12)[/tex]

[tex]90=4A[/tex]

Dividing both sides by 4, we get;

[tex]22.5 =A[/tex]

Thus, the area of the base of the cone is 22.5 square feet.

Hence, Option c is the correct answer.

Answer:

3300 was on 3% and 6700 on 2,5%

Step-by-step explanation:

We can say that 'a' represents the price that will go on 3% interest and 'b' 2,5% interest.

Therefore;

a + b = 10 000

And

0,03a + 0,025b = 283.5 (0,03 means 3% etc)

You can move 'b' to the other side to leave 'a' on the LHS

0,03a = 283.5 - 0,025b - - > (divide both sides by 0,03)

a=9450 - 0,8333b

Substitute this equation as 'a' in the first equation to get:

9450 - 0,8333b + b = 10 000 (move 9450 to the RHS to leave values with b on the LHS)

-0,8333b + b = 10 000 - 9450

0,1666b = 550 (divide both sides by 0,1666)

b = 3,300

Therefore 'a' will be :

a= 10 000 - 3 300

a = 6700

I hope this helps.

After solving the system of equations, the amount in the account with 3% interest was $844.50 and the amount in the account with 2.5% interest was $9155.50 after one year.

Let's assume the amount invested at 3% interest is x and the amount invested at 2.5% interest is y. We can set up the following system of equations:

x + y = 10000 (equation 1)

0.03x + 0.025y = 283.50 (equation 2)

Multiply equation 1 by 0.03 and equation 2 by 100 to eliminate decimals:

0.03x + 0.03y = 300 (equation 3)

3x + 2.5y = 28350 (equation 4)

Now, subtract equation 3 from equation 4:

3x + 2.5y - 0.03x - 0.03y = 28350 - 300

Simplify:

2.97x + 2.47y = 28050 (equation 5)

Multiply equation 1 by 2.47 and equation 2 by -2.97 to eliminate y:

2.47x + 2.47y = 24700 (equation 6)

-2.97x - 2.97y = -842.25 (equation 7)

Add equation 6 and equation 7:

2.47x + 2.47y - 2.97x - 2.97y = 24700 - 842.25

Simplify:

-0.5x = -422.25

Divide both sides by -0.5:

x = 844.50

Substitute the value of x back into equation 1:

844.50 + y = 10000

Subtract 844.50 from both sides:

y = 9155.50

Therefore, there was $844.50 in the account with 3% interest and $9155.50 in the account with 2.5% interest after one year passed.

Using trigonometric ratios, the length in inches of the given triangle is 22 inches.

Given a right angled triangle.

The length of the hypotenuse is also given.

We can find the length of "a" using the sine trigonometric ratio.

We know that,

Sine of any angle is defined as the ratio of the opposite side to the hypotenuse of a right angled triangle.

Using the sine function here for the angle 30°,

sin (30°) = opposite side / adjacent side

sin (30°) = a / 44

Or,

a / 44 = sin (30°)

We know that sin (30°) = 1/2.

So,

a / 44 = 1/2

Multiplying both sides by 44, we get,

a = 44 / 2

a = 22 inches

Hence the length is 22 inches.

Answer:

please explain it better.

Step-by-step explanation:

The student needs to use the average rate of change formula correctly. For the function f(x) = 0.5x^2 and the interval [-4, -2], the correct average rate of change is -3.

The student is looking to find the average rate of change of the function f(x) = 0.5x^2 over the interval [-4,-2]. The average rate of change of a function over the interval [a, b] is calculated by the formula: (f(b) - f(a)) / (b - a).

For our function and interval this calculates to (f(-2) - f(-4)) / (-2 -(-4)). f(-2) is 0.5(-2)^2 = 2, and f(-4) is 0.5(-4)^2 = 8. Substituting into the formula gives (2 - 8) / (-2 -(-4)) = -6 / 2 = -3. So the correct average rate of change for f(x) = 0.5x^2 over the interval [-4,-2] is -3.

Answer:

c) 20,000

Step-by-step explanation:

Number of digits = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 = 10,

Number of vowel letters = a, e, i, o, u = 5

Repetition of digits is permitted but repetition of vowel letters is not permitted

Let the password be presented in dash form as shown below:

____ ____ ____ ____ ____ =

  D       D       D       V       V

where:

D = possible number of digits to fill the spot

V = possible number of vowels to fill the spot

Since repetition of digits is permitted, each spot marked as D can be filled with any one of 10 digits from 0 - 9

The first spot marked V has 5 possible options (a, e, i, o, u) & the second spot marked V only has 4 possible options (since repetition of vowels is not permitted).

We then place the number of possibilities in each spot and multiply them to determine the number of passwords possible

10  *  10  *  10  *  5  *  4 = 20,000

Therefore, the number of possible passwords is 20,000
