Answer:

35%

Step-by-step explanation:

The percent change is calculated as

[tex]\frac{change}{original}[/tex] × 100%

change = 222.75 - 165 = 57.75, thus

% change = [tex]\frac{57.75}{165}[/tex] × 100% = 0.35 × 100% = 35%

The percent change in value is 35%, and it is a percentage increase.

To calculate the percent change in value, we use the formula: ((new value - original value) / original value) * 100. In this case, the new value is $222.75 and the original value is $165. Plugging in these values, we get ((222.75 - 165) / 165) * 100 = 35%. Therefore, the percent change in value is 35%. Since the value has increased, it is a percentage increase.

Step-by-step explanation:

Defining x the weight of each quarter grades (4x for the 4 quarter grades), then the weight of the mid-term exam grade is 2x, and the weight of the final exam is 4x. The addition of all grades is 4x + 2x + 4x = 10x (this represents the combination of grades that makes the final course grade).

Answer:

  A) 21.02°

  B) 26.74°

  C) 22.79°

  D) DNE

Step-by-step explanation:

We can solve the equation for the angle:

  D = 672·sin(2θ)

  D/672 = sin(2θ)

  arcsin(D/672) = 2θ

  θ = arcsin(D/672)/2

A) For D = 450, θ = arcsin(450/672)/2 = 21.0198° ≈ 21.02°

B) For D = 540, θ = arcsin(540/672)/2 = 26.7363° ≈ 26.74°

C) For D = 480, θ = arcsin(480/672)/2 = 22.7923° ≈ 22.79°

D) For D = 720, θ = arcsin(720/672)/2 = DNE

Answer:

Step-by-step explanation:

The question is not properly structured and the equation is also incorrect. Here is the correct question.

You and some friends went to a haunted house on Halloween. The mummy scared one friend so much that she jumped into the air! The equation h= -4t²+ 2t models her jump where h is her jumps height in feet t seconds after the mummy scares her. When did she reach her maximum.

Give the equation h= -4t²+ 2t that models my friend jump where h is her jumps height in feet t seconds, At maximum height, her velocity will be zero i.e

Vmax = 0m/s

Velocity is the rate of change in distance of a body i.e V = dh/dt

Given  h= -4t²+ 2t

V = dh/dt = -8t+2

Since v = 0m/s

0 = -8t+2

-8t = -2

t = -2/-8

t = 0.25 secs

She reaches her maximum height after 0.25 seconds

We have been given that a parabola has vertex [tex](-8,-7)[/tex] and also passes through the point [tex](-7,-4)[/tex]. We are asked to write the equation of the parabola in vertex form.

We know that vertex form of parabola in format [tex]y=a(x-h)^2+k[/tex], with a vertex at point (h,k).

Let us write equation of parabola using our given information as:

[tex]y=a(x-(-8))^2-7[/tex]

[tex]y=a(x+8)^2-7[/tex]

Now we will substitute the coordinates of point [tex](-7,-4)[/tex] to solve for a as:

[tex]-4=a(-7+8)^2-7[/tex]

[tex]-4=a(1)^2-7[/tex]

[tex]-4+7=a-7+7[/tex]

[tex]3=a[/tex]

Therefore, our required equation would be [tex]y=3(x+8)^2-7[/tex].

Answer:

I'm not sure which one 25% i put the wrong number in

If you sleep 6 hours out of 24 hours, you sleep for 25% of the time.

To find the percentage of time spent sleeping, one must divide the number of hours slept by the total number of hours in a day and then multiply by 100. In this case, a person sleeps for 6 hours in a 24-hour day. The calculation is as follows:

Percentage of time spent sleeping = (Number of hours slept / Total number of hours in a day) × 100%

Percentage of time spent sleeping = (6 hours / 24 hours) × 100%

Percentage of time spent sleeping = 0.25  × 100%

Percentage of time spent sleeping = 25%

Therefore, sleeping for 6 hours in a 24-hour period means a person spends 25% of their time sleeping.

The future value of $82,100 invested at a 4.3% annual interest rate compounded continuously for 2 years using the formula V = Pe^{rt}, will be approximately $90,137.30.

Your question involves the calculation of the future value of an investment using the formula for continuous compound interest, in this case $82,100 invested at an annual rate of 4.3%, over 2 years. This scenario relies on the mathematical concept of compound interest, which means the interest earned on the initial investment is added to the principal, and this combined amount earns interest as well.

Using the formula V = Pe^{rt}. where:
P = principal amount (initial investment) = $82,100,
r = annual nominal interest rate (decimal) = 4.3/100 = .043,
t = time the money is invested for = 2 years,
e = Euler's number (approx. 2.71828).

The calculation then becomes: V = $82,100 * e^(0.043 * 2) = $82,100 * e^(0.086). Using a calculator to do the exponentiation and the multiplication, the balance in the account after 2 years would approximately be $90,137.30.

Answer:

15

Step-by-step explanation:

Since a square has 4 sides, that means that each side is equal to the other three sides because it is a square. If so, we do 60/4 to get is 15. To check the answer 15x4 is equal to 60.

Answer:

each side will be 15

Step-by-step explanation:

because if its a square and all the sides are the same lengh and one of the sides are 15 then all of the other sides will also be 15,so that will equal 60.

The expression (x+1)(x+3)(x+5) can be expanded to the form ax^3+bx^2+cx+d with a, b, and c as positive integers and d as negative by first multiplying (x+1) and (x+3) to get x^2+4x+3, which is then multiplied by (x+5) to obtain x^3+9x^2+23x+15.

To show that

(x+1)(x+3)(x+5)

can be written in the form

ax^3+bx^2+cx+d  where a,b and c are all positive integers, and d is a negative integer, perform multiplication for the given factors as follows:

Firstly, multiply (x+1) and (x+3) which yields x^2+4x+3.

Then, multiply this result by (x+5) which gives the final form: x^3+9x^2+23x+15.

So, a=1, b=9, c=23, and d=15 proving the original expression can be written in the stated form.

Answer:

Variance = 78.5

Standard Deviation = 8.86

Step-by-step explanation:

Given

Mean = 81

Required

Find the variance and standard deviation of the given set of data.

Provided that we already know the mean; to calculate the variance, follow the steps below.

1. Subtract the mean from each data.

76 - 81 = -5

87 - 81 = 6

65 - 81 = -16

88 - 81 = 7

67 - 81 = -14

84 - 81 = 3

77 - 81 = -4

82 - 81 = 1

91 - 81 = 10

85 - 81 = 4

90 - 81 = 9

2. Square these results

-5² = 25

6² = 36

-16² = 256

7² = 49

-14² = 196

3² = 9

-4² = 16

1² = 1

10² = 100

4² = 16

9² = 81

3. Sum these results

Sum = 25+36+256+49+196+9+16+1+100+16+81

Sum = 785

4. Calculate variance by dividing the sum by n - 1 where n = 11

So, n - 1 = 11 - 1 = 10

Variance = 785/10

Variance = 78.50

5. Calculate standard deviation by finding the square root of variance

S.D = √78.50

S.D = 8.86 (Approximated)

Step-by-step explanation:

12 times 12 is 144 so 12.in each row

Helen will use 12 glass tiles in one row of her plate, as the square plate has a total area of 144 square centimeters and each tile measures one square centimeter.

The student's question involves calculating the number of glass tiles Helen would use in one row of a square plate, given that she has 144 square centimeters of glass tiles and each tile measures one square centimeter. To determine the number of tiles in one row, we need to remember that the area of a square is equal to the side length squared. Since the total area is 144 square centimeters, we take the square root of 144 to find the length of one side, which is 12 centimeters. Therefore, Helen will use 12 glass tiles in one row of her plate, as there would be 12 tiles lengthwise and 12 tiles widthwise to make up the total area of 144 square centimeters.
