Answer:

1:19PM

Step-by-step explanation:

To solve this, we can first add up the minutes.

We convert to a fraction because if there are 60 minutes in an hour, we need to find out how many hours are in 79 minutes.

Now, we can add up the hours.

Therefore, the game ended at 1:19 PM

If  activity fee for an arts camp is $250. If the activity fee increases by 20% then $300 will be the new activity fee.

Percentage is a relative value indicating hundredth parts of any quantity.

Given activity fee for an arts camp is $250.

The activity fee increases by 20%.

We need to convert percent to decimal.

20%=20/100=0.2

We need to find what is 20% of $250.

So 0.2*250=50

So 50 is 20% of 250.

As activity fee increases by 20%  the new fee will be

$250+$50=$300.

Therefore $300 will be the new activity fee.

Answer:

C

Step-by-step explanation:

to be a linear function the change in X and the change in Y has to be the same hence slope

A. x changes by+ 1 see 2,3,4,5, and y changes by +5, +7, +9 so A is not a linear function

B. X changes by -1 in all, y changes +1 for first 3 then -1 last, so B is not a linear function

C. X changes by +1 for all and y changes by -6 for all so is it is a linear function

D x changes by +1 for all and y changes by -1, +1, +3 so no linear fn.

The interest Pedro will have to pay is $5200

From the question, we have the following parameters that can be used in our computation:

Principal = $32.500

Rate = 4% simple interest

Time = 4 years

The formula of simple iinterest is

I = Principal * Rate * Time

substitute the known values in the above equation, so, we have the following representation

I = 32500 * 4% * 4

Evaluate

I = 5200

The distance of the run Will be 16miles and the Distance of the bicycle race will be 81 miles.

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.

Distance = average velocity × time

Let the time and distance of the run, respectively, be t₁ and.d₁

Let those of the bicycle race be t₂ and d₂

From the question,

t₁ + t₂ = 5

d₁ = 8t₁

d₂ = 27t₂

Total distance = 97

8t₁ + 27t₂ = 97

8 ( 5 - t₂ ) + 27t₂ = 97

40 - 8t₂ + 27t₂ = 97

40 + 19 t₂ = 97

19t₂ = 57

t₂ = 3 hours

t₁ + t ₂ = 5

t₁ = 5 - t₂

t₁ = 5 - 3 = 2 hours

Now the distances are calculated as:-

d₁ = 8t₁ = 8 x 2 = 16 miles

d₂ = 27t₂ = 27 x 3 = 81 miles

Therefore the distance of the run Will be 16miles and the Distance of the bicycle race will be 81 miles.

The dimensions of the area is 110 x 220 meters.

A mathematical space's dimension is defined informally as the smallest number of coordinates required to specify every point within it. Thus, a line seems to have a dimension of one since only one coordinate is required to identify a point on it - for example, that point at 5 on the number line.

Given:

The entire cost of constructing the wall as well as fence is $13.200.

the wall costs $50.00/m.

the fence costs $5.00/m

let x=width

2x=length and wall

length of fencing=x+x+2x=4x

Now,

5*4x+50*2x=13200

A = 54 yd²

Step-by-step explanation:

To find the approximate value of θ, we can use the concept of trigonometric ratios in a right triangle.

In the given diagram, the radius intersects the unit circle at the point (0, 1). This means that the angle formed between the positive x-axis and the radius is θ.

We can see that the adjacent side of the right triangle formed is 1, and the hypotenuse is the radius of the circle, which is given as 5.5.

Using the cosine function, we have:

cos(θ) = adjacent / hypotenuse

cos(θ) = 1 / 5.5

To find θ, we can take the inverse cosine (arccos) of both sides:

θ = arccos(1 / 5.5)

Using a calculator to evaluate the arccos(1 / 5.5), we find:

θ ≈ 1.447 radians (rounded to three decimal places)

Therefore, the approximate value of θ is approximately 1.447 radians.

Answer:

\(y=3x\) (Equation 1)

\(y=x-2\) (Equation 2)

We can substitute Equation 1 into Equation 2 like so:

\(y=x-2\)

\(3x=x-2\)

Subtract x from both sides:

\(2x=-2\)

Divide both sides by 2:

\(x=-1\).

Substitute \(x=-1\) into Equation 1 to find y:

\(y=3x\)

\(y=3(-1)\)

\(y=-3\)

Cooper ran 286 miles in 21 weeks.

Answer:

x = 45°

Step-by-step explanation:

We know that (2x + 45)° and x° are adjacent angles, so they add up to 180°.

(2x + 45) + x = 180

3x + 45 = 180

3x = 180 - 45

3x = 135

x = \(\frac{135}{3}\)

x = 45°

Answer:

\(P(x \le 3.24) = 0.97725\)

Step-by-step explanation:

Given

\(\bar x = 2.5\)

\(\sigma = 0.37\)

Required

Percentage that is not more than 3.24

The above implies that:

\(x = 3.24\)

Calculate z score

\(z = \frac{x - \bar x}{\sigma}\)

\(z = \frac{3.24 - 2.5}{0.37}\)

\(z = \frac{0.74}{0.37}\)

\(z = 2\)

So, the probability is represented s:

\(P(x \le 3.24) = P(z \le 2)\)

From z probability

\(P(z \le 2) = 0.97725\)

Hence:

\(P(x \le 3.24) = 0.97725\)

Answer:

sin(100°) = 0.985

sin(-100°) = -0.985

Step-by-step explanation:

In a unit circle, each point (x, y) on the circumference corresponds to the coordinates (cos θ, sin θ), where θ represents the angle formed between the positive x-axis and the line segment connecting the origin to the point (x, y).

Therefore, sin(100°) equals the y-coordinate of the point (-0.174, 0.985), so:

\(\boxed{\sin(100^{\circ}) = 0.985}\)

Similarly, sin(-100°) equals the y-coordinate of the point (-0.174, -0.985), so:

\(\boxed{\sin(-100^{\circ}) = -0.985}\)

In the unit circle the value of sin (100) = 0.985 and the value of sin (-100) = -0.985, in three decimal places.

The value of the sine of the angles is calculated by applying the following formula as follows;

The value of sin (100) is calculated as follows;

sin(100°) corresponds to the y-coordinate of the point (-0.174, 0.985) as given on the coordinates of the unit circle.

sin (100) = 0.985

The value of sin (-100) is calculated as follows;

sin(100°) corresponds to the y-coordinate of the point (-0.174, -0.985), as given on the coordinates of the circle.

sin (-100) = -0.985

Thus, in the unit circle the value of sin (100) = 0.985 and the value of sin (-100) = -0.985, in three decimal places.

Answer:

okay, so we have a wall that is 60 ft. The area of the wall because the wall is a square is just side squared. So the area of the wall is \(60^{2}\), which is 30 600 square feet. The mirror is 20 ft by 60 ft. So the area of the mirror, because its a rectangle is length times width, so that's 20 a 60 so 20 x 60 is gonna give me 1200 square feet. So if we take the area of the mirror and put that over the area, the wall we get 1200 over 30 600, which reduces to one over three. So the mirror is one third the area of the wall.

Surface Area of cuboid = 2 (lb + bh + hl)

According to the question :

length = x, width = x-5, height = 0.5x

250 = 2 ( x × (x-5) + (x-5) × 0.5x + 0.5x × x )

250 = 2 ( x² - 5x + 0.5x² - 2.5x + 0.5x²)

250 = 2 ( x² - 5x + x² - 2.5x )

250 = 2 ( 2x² - 7.5x )

250 = 4x² - 15 x

4x² - 15x -250 = 0

Answer:

To find the total distance, we need to add up the distance the student ran in the first 5 days and the distance the student ran in the next 5 days.

Distance for the first 5 days = 3 1/2 miles/day × 5 days = 17.5 miles

Distance for the next 5 days = 4 1/4 miles/day × 5 days = 21.25 miles

Total distance = Distance for the first 5 days + Distance for the next 5 days

Total distance = 17.5 miles + 21.25 miles

Total distance = 38.75 miles

Therefore, the student ran a total of 38.75 miles during these 10 days.
