Solution :-

To find the least number which when divided by 6, 15 and 18 leaves a remainder 5 in each case, we have to find the L.C.M. of 6, 15 and 18 and then add 5 in that number.

L.C.M. of 6, 5 and 18  

6 = 2*3

15 = 3*5

18 = 2*3*3

L.C.M. of 6, 15 and 18 = 2*3*3*5 = 90

Now,  

5 + 90 = 95

Hence, 95 is the least number which when divided by 6, 15 and 18 leaves a remainder 5 in each case.

Let us check our answer.

1) 95/6

Quotient = 15

Remainder = 5

2) 95/15

Quotient = 6

Remainder = 5

3) 95/18

Quotient = 5

Remainder = 5

So, the required number is 95.

Answer:

3. markup: $150

selling price: $300

4. markup: $19.20

selling price: $67.20

5. markup: $55

selling price: $165

6. markup: $90

selling price: $450

7. markup: $3.75

selling price: $16.25

8. markup: $7.14

selling price: $27.54

Step-by-step explanation:

To find the markup of an item you multiply the initial value of the item by the percentage it's being marked up by. To find the selling price, you add the markup to the initial value. Let's use question 3 as an example:

3. The recliner is being marked up by 100%. To find the markup, we can convert 100% into decimal form and then multiply it by the initial value 150:

100% = 1

150 * 1 = 150

The markup is 150.

To find the selling price we add the markup to the initial value:

150 + 150 = 300

The selling price is 300.

I applied this method to all of the questions.

Answer:

  a)  3.491 in/s

  b)  3.333 RPM

  c)  0.349 rad/s

Step-by-step explanation:

We know the arc length for a given radius and angle is ...

  s = rθ

so the linear speed along the arc is ...

  s' = rθ' = (10 in)(20π/180 rad/s) = 10π/9 in/s ≈ 3.491 in/s

__

The rotation rate of 20°/s is an angular velocity of ...

  (20°/s)(60s/min)(1 rev/360°) = 3.333 RPM

__

In the first part, we found the angular speed to be π/9 radians/sec. That's about ...

  π/9 rad/s ≈ 0.349 rad/s

Step-by-step explanation:

tanα = [tex]\frac{opp}{adj}[/tex]→[tex]tan 50^{o} = \frac{x}{28}[/tex]

x = 28 tan 50° = 33.4

Answer:

The value of missing x = 33.37 units

Step-by-step explanation:

Given

Ф = 50°

We know that

tan Ф = opposite/adjacent

Here:

opposite = x

adjacent = 28

so

tan Ф = opposite/adjacent

tan 50 = x/28

x = 28 × tan 50

  =33.37

Therefore, the value of missing x = 33.37 units.

Step-by-step explanation:

Answer:

20 roses cost $91.65

Step-by-step explanation:

Given

1 dozen rose = $54.99

Required

Determine the cost of 20 roses

To calculate the proportion, we make use of:

[tex]c = kx[/tex]

Where

c = cost

k  = constant of proportionality

x = number of roses

For a dozen rose

[tex]c = 54.99[/tex] and [tex]x = 12[/tex]

So:

[tex]c = kx[/tex]

[tex]54.99 = k * 12[/tex]

[tex]54.99 = 12k[/tex]

[tex]k = \frac{54.99}{12}[/tex]

[tex]k = 4.5825[/tex]

For 20 roses

[tex]c = kx[/tex]

Where

[tex]k = 4.5825[/tex]

[tex]x = 20[/tex]

[tex]c = 4.5825 * 20[/tex]

[tex]c = 91.65[/tex]

Answer:

No, this is not a function because this would not pass the vertical line test in which only one y point can be on one x axis not two. As you can see, on (0,3) and (0,(-2)) are on the same x axis. So, not a function.

Step-by-step explanation:

basically just find the ones that do not cross and those are parellel.

Answer:

52 cards:

26 red and 26 black

P(R) = probability of picking a red card

P(B) = probability of picking a black card

P(R) = P(B) = ¹/₂

If with replacement:

P(R∩B) = (¹/₂)(¹/₂) = ¹/₄

If without replacement:

P(R∩B) = (¹/₂)(²⁶/₅₁) = ¹³/₅₁

8 Balls:

3 red and 5 white

P(R) = probability of picking a red ball

P(W) = probability of picking a white ball

P(R) = ³/₈

P(W) = ⁵/₈

If with replacement:

P(R∩W) ∪ P(W∩R) = (³/₈)(⁵/₈) + (⁵/₈)(³/₈)

= ¹⁵/₆₄ + ¹⁵/₆₄

= ³⁰/₆₄

= ¹⁵/₃₂

If without replacement:

P(R∩W) ∪ P(W∩R) = (³/₈)(⁵/₇) + (⁵/₈)(³/₇)

= ¹⁵/₄₂ + ¹⁵/₄₂

= ³⁰/₄₂

= ⁵/₇

Answer:

x= 1/5y +1/5 have a good day whoever you are :D

Step-by-step explanation:

Step 1: Flip the equation.

5x−5=y−4

Step 2: Add 5 to both sides.

5x−5+5=y−4+5

5x=y+1

Step 3: Divide both sides by 5.

5x /5 = (y+1) /5

x= 1/5y +1/5

Answer:

5x-y=-1

Step-by-step explanation:

y-4=5x-5

take 5x on the other side and also take -4 on the other side . the numbers must change sines when they go on there other side

-5x+y=-5+4

-5x+y=-1

divide both sides by -1

5x-y=1

Answer:

4 ≥ g

Step-by-step explanation:

Since 4 x 5=20 I started there and went one less because of the .95¢

so I started with the equation 4.95 x 4 which got the product $19.80 and I know that's as high as we can go within 20.

We also know she could play less than 4 games and stay within budget so that's why I used the ≥. You could also divide 20 by 4.95 for a quick and easy answer :)

Step-by-step explanation:

The number of butterfly notebooks should they order this month approximately will be 43.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The Miracle Wings Bug Exhibition hall sells bug-formed scratch pads in their gift shop. Last month, they sold 35 butterfly notepads and 55 ladybug journals.

The ratio of butterfly notebooks and ladybug notebooks will be given as,

⇒ 35 / 55

⇒ 7 / 11

The scratch pad was well known to the point that they believe should arrange more this month. They intend to arrange 110 ladybug notepads this month.

Let 'x' be the number of butterfly notebooks. Then the number of ladybug notebooks will be (110 - x).

If they keep the same ratio. Then the value of 'x' is given as,

x / (110 - x) = 7 / 11

11x = 770 - 7x

18x = 770

x = 42.77

The number of butterfly notebooks should they order this month approximately will be 43.
