plz do this ill mark brainly
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:
33.4
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.

Two cards are drawn in succession from a standard 52-card deck.1. What is the probability that the first card is red and the second card is black(A) If the cards are drawn without replacement?(B) If the cards are drawn with replacement?2. Two balls are drawn in succession out of a box containing 3 red and 5 white balls. Find the probability that at least 1 ball was red, given that the first ball was(A) Replaced before the second draw(B) Not replaced before the second drawContext Header: Conditional ProbabilityContext Section:Conditional Probability is a calculation of the likelihood of an occurrence provided that another event has already occurred. Conditional probability A provided B is generally written as:P(A/B)=P(A∩B)P(B)
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

Find the least number that when divided by
60. 120 and 180 leaves a remainder 5 in each case.
Answer:
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.

A florist sells a dozen long-stemmed red roses for $54.99. In honor of their 16th wedding anniversary, a man wants to buy 20 roses for his wife. (Hint: How many roses are in one dozen?)
Let c represent the cost of 20 roses. Write a proportion, in terms of c, that can be used to solve for the cost of 20 roses.
What will the roses cost (in dollars)?
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]
A wheel of radius 10 inches is rotating 20°/sec. What is the linear speed in in/sec and the angular speed in RPM? (Round your answers to three decimal places) ____ in/sec ____ RPM What is the angular speed in radians/sec? ____ radians/sec
9514 1404 393
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
find the greatest common factor of 26 and 14

The Wonder Wings Insect Museum sells bug-shaped notebooks in their gift shop. Last month, they sold 35 butterfly notebooks and 55 ladybug notebooks. The notebooks were so popular that they want to order more this month. They plan to order 110 ladybug notebooks this month. If they keep the same ratio, how many butterfly notebooks should they order this month?
Answer:
70
Step-by-step explanation:
The number of butterfly notebooks should they order this month approximately will be 43.
What are ratio and proportion?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.

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
