Answer:

c.) $34.00 a ticket

Step-by-step explanation:

Since you're trying to figure out how much a discounted ticket is you have to take the 15% off. So 15% of 40 is 6. Now take the 6 off of 40 (40-6) you will get 34. So the answer is $34.

I hope this helps!

Answer:

2.88m/s

Step-by-step explanation:

By using the law of conservation of momentum

Initial momentum = final momentum

v = is their combined velocity afterwards

Solving equation (1) for v

V = 2.88 m/s

Therefore the velocity afterward is 2.88 m/s.

Answer:

your answer  is 200 if you add 84 and 116 but is you add 25 82 213 and 97 it will be 417

Step-by-step explanation:

The balance at the end of the month is $83.

Checkbook balance = $300

Amount withdrawn = $25 + 82 + $213 + $97 = $417

Amount deposited = $84 + $116 = $200

Therefore, the balance at the month end will be:

= $300 - $417 + 200

= $83

Answer:

y=14

Step-by-step explanation:

Put the x value where it belongs

y=4(3)+2    Now do the math ( id.k what to say here for the problem other than that lol)

y=12+2

y=14

Answer:

(3, 14).

Step-by-step explanation:

Plug x = 3 into the first equation:

y = 4(3) + 2

y = 12 + 2

y = 14

So x = 3, y = 14.

Answer: Mr. Shahoian need to purchase 9 pieces of fencing.

Step-by-step explanation:

Given: Length of fencing around the flower beds in his backyard = 166.25 ft

The fencing is sold in lengths of 19 ft each.

Number of pieces of fencing = (Length of fencing ) ÷ (19)

i.e. Number of pieces of fencing = 166.25 ÷ 19

= 8.75 ≈ 9

Hence, Mr. Shahoian need to purchase 9 pieces of fencing.

Answer:

3 of the pyramids

Step-by-step explanation:

Given:

Hexagonal Prism

Hexagonal based pyramid

Required

How many of the pyramid will fill up the prism

To do this, we start by calculating the volumes of both shapes.

Let V1 be the volume of the hexagonal prism

[tex]V_1 = \frac{3\sqrt{3}}{2}a^2h[/tex]

Where: a = base and h = height

Let V2 be the volume of the hexagonal based pyramid

[tex]V_2 = \frac{\sqrt{3}}{2}a^2h[/tex]

Where: a = base and h = height

The number of the pyramid that can occupy the prism is calculated by dividing V1 by V2

[tex]Number = \frac{V_1}{V_2}[/tex]

[tex]Number = \frac{3\sqrt{3}}{2}a^2h /\frac{\sqrt{3}}{2}a^2h[/tex]

Convert division to multiplication

[tex]Number = \frac{3\sqrt{3}}{2}a^2h * \frac{2}{\sqrt{3}a^2h}[/tex]

[tex]Number = \frac{3\sqrt{3}}{2} * \frac{2}{\sqrt{3}}[/tex]

[tex]Number = \frac{3\sqrt{3}}{1} * \frac{1}{\sqrt{3}}[/tex]

[tex]Number = \frac{3*1}{1} * \frac{1}{1}[/tex]

[tex]Number = 3[/tex]

Answer: The length of AB = 8 units

Step-by-step explanation:

Given: In parallelogram ABCD, Sides A B and D C are parallel.

The length of AB is 4q minus 8 and the length of DC is q + 4.

Since opposite sides of parallelogram is parallel and equal.

So [tex]4q-8=q+4[/tex]

[tex]\Rightarrow\ 4q-q=4+8\\\\\Rightarrow\ 3q=12\\\\\Rightarrow\ q=4[/tex]

Length of AB = 4q-8=4(4)-8=16-8=8 units

Hnece, the length of AB = 8 units

Answer:

- [tex]\frac{2}{3}[/tex] x

Step-by-step explanation:

Given

[tex]\frac{4x-8x^2}{12x-6}[/tex] ← factorise numerator and denominator

= [tex]\frac{4x(1-2x)}{6(2x-1)}[/tex] ← factor out - 1 from (1 - 2x) on numerator

= [tex]\frac{-4x(2x-1)}{6(2x-1)}[/tex] ← cancel the common factor (2x - 1)

= [tex]\frac{-4x}{6}[/tex] ← cancel 4 and 6 by 2

= - [tex]\frac{2}{3}[/tex] x

Simplifying the expression will give us: [tex]\frac{4x-8x^2}{12x-6} = \frac{-2x}{3}[/tex]

Given the expression, [tex]\frac{4x-8x^2}{12x-6}[/tex], we are required to simplify the expression as follows:

Step 1: Factorize the denominator and the numerator.

[tex]\frac{4x-8x^2}{12x-6}\\\\=\frac{(1 - 2x)4x}{(2x - 1)6}[/tex]

Step 2: Rewrite the fraction by factoring out -1 from the numerator.

[tex]=\frac{(2x - 1)-4x}{(2x - 1)6}[/tex]

Step 3: Divide the numerator and denominator by (2x - 1) respectively.

[tex]=\frac{-4x}{6}[/tex]

Step 4: Divide the numerator and denominator by 2 respectively.

[tex]=\frac{-2x}{3}[/tex]

Therefore, simplifying the expression will give us: [tex]\frac{4x-8x^2}{12x-6} = \frac{-2x}{3}[/tex]

Answer:

Each shirt is $8

Step-by-step explanation:

80÷10 = 8

Answer:

$8

Step-by-step explanation:

Form your equation, there are 10 shirts at x price, and they equal $80:

10x = $80

solve for x by dividing both sides by 10

10x/10 = $80/10

x = $8

Answer:

A. On the first day, 3 leaves fall.

B. D. The number of leaves that fall on a given day is 2 times the number of leaves that fell on the previous day.

Step-by-step explanation:

Given

[tex]f(n) = 3(2)^n[/tex]

Solving (a) The meaning of 3.

3 represents the initial number of leaves (i.e. the first day) and this proved as follows.

On the first day, n = 0.

Substitute 0 for n in [tex]f(n) = 3(2)^n[/tex]

[tex]f(0) = 3(2)^0[/tex]

[tex]f(0) = 3*1[/tex]

[tex]f(0) = 3[/tex]

Solving (b) The meaning of 2.

2 represents the rate which leaves fall down.

In (a)

[tex]f(0) = 3[/tex]

Take n = 1

Substitute 1 for n in [tex]f(n) = 3(2)^n[/tex]

[tex]f(1) = 3(2)^1[/tex]

[tex]f(1) = 3*2[/tex]

[tex]f(1) = 6[/tex]

When f(1) is divided by f(0), the result 2. So, the number of leaves doubles everyday

Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k).
