Bryan has enough to buy skateboard as it will cost $44.94

Step-by-step explanation:

Original price = $70.00

Discount = 40%

Amount of discount = 40% of original price

Amount of discount = [tex]\frac{40}{100}*70[/tex]

Amount of discount = [tex]\frac{2800}{100}[/tex]

Amount of discount = $28

Price after discount = Original price - amount of discount

[tex]Price\ after\ discount=70-28 = $42\\[/tex]

Sales tax = 7% = [tex]\frac{7}{100} = 0.07[/tex]

Sales tax amount = Price after discount (0.07)

[tex]Sales\ tax\ amount= 42(0.07) = $2.94\\[/tex]

Price of skateboard = Price after discount + sales tax

Price of skateboard = 42+2.94 = $44.94

Answer:

n = 8, w = 3 and perimeter = 122.83 units.

Step-by-step explanation:

Let the angle M is the angle between the equal sides of isosceles JAM.

So, JM = MA

⇒ 35 = 4n + 3

⇒ 4n = 32

⇒ n = 8 (Answer)

Now, if ∠ J = 14w - 1 and ∠ M = 98°, then

2(14w - 1) + 98 = 180

⇒ 2(14w - 1) = 82

⇒ 14w - 1 = 41

⇒ w = 3 (Answer)

Now, draw a perpendicular bisector on JA from vertex M and it meets JA at P say.

So, Δ MPJ will be a right triangle with ∠ J = (14w - 1) = 41° {Since w = 3}

Hence, [tex]\cos 41 = \frac{JP}{JM} = \frac{JP}{35}[/tex]

⇒ JP = 35 cos 41 = 26.415

So, JA = 2 × JP = 52.83  

So, the perimeter of Δ JAM is = 35 × 2 + 52.83 = 122.83 units (Answer)

Answer:

Adult Ticket cost $9.50 and Children Ticket cost $7.00

Step-by-step explanation:

Let single adult tickets cost "a" and single children ticket cost "c"

6 adult and 2 children ticket is $71, we can write:

6a + 2c = 71

Also,

3 adult and 4 children tickets cost $56.50, so we can write:

3a + 4c = 56.5

We multiply 2nd equation by "-2", to get:

-2 * (3a + 4c = 56.5) = -6a -8c = -113

Now we add this equation with 1st and eliminate a and solve for c:

6a + 2c = 71

-6a -8c = -113

-------------------

-6c = -42

c = -42/-6

c = 7

To find a, we can plug this into 1st equation and then get our answer.

6a + 2c = 71

6a + 2(7) = 71

6a + 14 = 71

6a = 57

a = 57/6

a = 9.5

Hence,

Adult Ticket cost $9.50 and Children Ticket cost $7.00

Answer: Damien has 21 red pieces

Step-by-step explanation:

First, 7/8 of the rectangle is coloured red.

Then, the 7/8 was cut into a size 1/24 of the rectangle each.

That consequently means that 24 of those pieces will form the whole shape.

Since red covers 7/8 of the rectangle, the number of red pieces invariably becomes

⅞ × 24 pieces, which is equal to 21 pieces

Therefore, Damien has cut the red part of the rectangle into 21 pieces

Final answer:

Damien has 21 red pieces after dividing the red part of the rectangle, which is 7/8, into pieces that are each 1/24 of the whole rectangle.

Explanation:

To find the number of red pieces Damien has, we first determine the fraction of the rectangle that is colored red, which is 7/8. Then, we find the size of each piece that Damien cuts, which is 1/24 of the whole rectangle.

Since each piece is 1/24, and Damien is cutting up only the red part which is 7/8 of the whole, we calculate the number of pieces by dividing the red part by the size of each piece: number of red pieces = (7/8) / (1/24).

To do this division, we multiply by the reciprocal of the divisor: (7/8) * (24/1) = 21. Therefore, Damien has 21 red pieces.

Answer:

5 meters/second

Step-by-step explanation:

100meters/20 seconds gives the average of 5 m/s

Final answer:

The runner's speed in the hundred meter race completed in 20 seconds is 5 meters per second. To calculate this, divide the total distance (100 meters) by the total time (20 seconds).

Explanation:

To calculate the speed of the runner in meters per second, we divide the distance travelled by the time it took to complete that distance. In this case, the runner completed a 100 meter race in 20 seconds. Using the formula speed = distance/time, we find that the speed is 100 meters / 20 seconds = 5 meters per second.

If the sprinter accelerates for the first 20 meters and then maintains that speed for the remainder of the 100-meter dash, we must first calculate the acceleration period's average speed. As it takes 20 seconds to run 100 meters, the speed over those 20 meters is also 5 meters per second. Once the sprinter reaches this speed at 20 meters, he will continue at this constant speed for the remaining 80 meters. Thus, the time to complete the race is the time taken to accelerate for 20 meters plus the time taken to run the remaining 80 meters at 5 m/s.

The maximum height reached is greater than 12m, hence the ball reach a height of 12m

The height of the toy cannon all launched is expressed as [tex]h(t) = -5t^2 + 20t + 4[/tex]

h is the height reached by the ball

t is the time taken by the ball to reach its maximum height

A) In order to determine whether the ball reached the height of 12m, we will have to substitute h = 12 into the formula as shown:

[tex]12= -5t^2 + 20t + 4\\ -5t^2 + 20t + 4 -12=0\\ 5t^2 - 20t +8=0\\[/tex]

Hence the equation that can be used to tell whether the ball reaches a height of 12 is [tex]5t^2-20t+8=0[/tex]

B) At the maximum height

dh/dt = 0

-10t + 20 = 0

-10t = -20

t = 20/10

t = 2

Get the maximum height reached

h(2) = -5(2)^2 + 20t + 4

h(2) = -5(4) + 20t + 4

h(2) = -20 + 20(2) + 4

h(2) = -20+40+4

h(2) = 24 m

Since the maximum height reached is greater than 12m, hence the ball reach a height of 12m

To determine whether the ball reaches a height of 12 meters, we set the height equation equal to 12 and solve the quadratic equation. Upon solving, we find that the ball reaches 12 meters, hence the answer to whether the ball reaches 12 meters is yes.

To determine whether the toy cannon ball reaches a height of 12 meters, we can set the height equation h(t) equal to 12 meters:

12 = -5t^2 + 20t + 4.

To solve for t, we need to rearrange the equation and solve the resulting quadratic equation:

0 = -5t^2 + 20t + 4 - 12

0 = -5t^2 + 20t - 8

This is the equation that can be used to tell whether the ball reaches a height of 12 meters. To determine if the ball does reach 12 meters, we solve for the roots of the equation:

-5t^2 + 20t - 8 = 0

Using the quadratic formula, we find the possible values for t. If there are real, positive solutions, it means the ball does reach 12 meters at those times.

Upon solving, we find that the ball indeed reaches a height of 12 meters because there are real, positive solutions for t.

Therefore, the answer to Part B is yes; the ball does reach a height of 12 meters.

Answer:

189.8 m

Step-by-step explanation:

See the diagram attached.

Now, the plane is at B and the two ships are at C and at D.

So, angle of depression of C from B is ∠ OBC = ∠ ACB = 35°

Again, the angle of depression of D from B is ∠ OBD = ∠ ADB = 25° ,

Now, from the right triangle Δ ACB,  

[tex]\tan 35 = \frac{AB}{AC} = \frac{265}{AC}[/tex]

⇒ [tex]AC = \frac{265}{\tan 35} = 378.5[/tex] m.

Similarly, from the right triangle Δ ADB,

[tex]\tan 25 = \frac{AB}{AD} = \frac{265}{AD}[/tex]

⇒ [tex]AD = \frac{265}{\tan 25} = 568.3[/tex] m.

Hence, the distance between the ships = CD = AD - AC = 568.3 - 378.5 = 189.8 m (Approx.) (Answer)

The distance apart is the two ships is 189.8 meters.

Given

A plane flying due east at 265 m above sea level, the angles of depression of two ships sailing due east measure 35 degrees and 25 degrees.

The angle of elevation, the angle of depression is the angle at which you would draw a line from a point on a horizontal line to intersect another point that falls below the line.

The plane is at B and the two ships are at C and at D.

Then,

The angle of depression of C from B is ∠ OBC = ∠ ACB = 35°.

And the angle of depression of D from B is ∠ OBD = ∠ ADB = 25°.

From the right triangle Δ ACB,

[tex]\rm Tan35= \dfrac{AB}{AC}\\\\ AC= \dfrac{265}{Tan35}\\\\AC = \dfrac{265}{0.70}\\\\AC =378.57[/tex]

Again in the right triangle Δ ADB,

[tex]\rm Tan 25=\dfrac{AB}{AD}\\\\AD =\dfrac{265}{Tan25}\\\\ AD = \dfrac{265}{0.46}\\\\AD =569.30[/tex]

Therefore,

The distance apart are the two ships is;

=  568.3 - 378.5 = 189.8 m

Hence, the distance apart is the two ships is 189.8 meters.
