Answer:
The retail price is $15.30
Step-by-step explanation:
To solve this, turn the percentage into a decimal. Do this by dividing it by 100.
180 ÷ 100 = 1.8
Then, multiply the supplier price by the decimal
8.5 × 1.8 = $15.30
solve for c: 2(c - 6) = 9c + 2

Calculate the average speed of an insect that walked 27 centimeters in 9 seconds. *
A 9 cm/s
B 27 cm/s
C 243cm/s
D 3 cm/s
Answer:
D) 3cm/s
Step-by-step explanation:
Speed (or velocity) is calculated with d/t (distance/time). From the multiple-choice options, we know the unit is cm/s, which makes it super convenient.
Now, using the equation and seeing that 27cm is the distance and 9s is the time, 27/9 =3.
Therefore, the answer is D, 3cm/s.

Answer:
Use the SOH CAH TOA
Step-by-step explanation:
Angle = 60°
x = opposite o
y = adjacent a
10√ 3 = hypotenuse h
To find x we use SOH {sineø = o/h}
Sin 60° = x/10√ 3
x=10√ 3 * sin 60
X=15
You can use Pythagoras theorem or CAH{cosø = a/h}
Cos 60°= y/10√ 3
y=Cos 60° * 10√ 3
y=5√ 3

-5x + 4y = 3
x = 2y - 15
solve for x and y
I'm failing please send help
Answer:
Let's solve for x.
−5x + 4y = 3
Step 1: Add -4y to both sides.
−5x + 4y+ −4y =3+ −4y
−5x = −4y +3
Step 2: Divide both sides by -5.
-5x divided by 5 = -4y+3 divided by -5
x=4/5y + −3/5

OA. 3
O B. 4
O C. 7
O D. 8
Answer:
C
Step-by-step explanation:
Answer:
B. 4
Step-by-step explanation:
5x - 2(2x-1) = 6 Distribute first the 2 to (2x-1)
5x - 4x + 2 = 6 Subtract 5x - 4x
x + 2 = 6 Transpose 2 to the right side by subtracting both side by 2

People at the state fair were surveyed about which type of lemonade they preferred. The results are shown below:
Pink Lemonade: 156 males, 72 females
Yellow Lemonade: 104 males, 48 females
Answer
Step-by-step explanation:
You would require the table with the number of males and females who prefer either pink or yellow lemonade at the state fair.
Pink Lemonade Yellow Lemonade TOTAL
Male 156 104 260
Female 72 48 120
TOTAL 228 152 380
P(pink lemonade | female) = 72 / (48 + 72) = 72 / 120 = 0.6
P(pink lemonade) = (156 + 72) / (156 + 72 + 104 + 48) = 228 / 380 = 0.6
Therefore, The event "prefers pink lemonade" and "female" are independent because P(pink lemonade | female) = P(pink lemonade) = 0.6
Independents events are events that can happen independently on their own. Events A and B are independent if P(A|B) = P(A).
The "prefer pink" event and "female" event are independent because [tex]P(P|F) = P(P) = 0.6[/tex]
To do this, we make the following representations:
[tex]P \to[/tex] Pink Lemonade
[tex]Y \to[/tex] Yellow Lemonade
[tex]M \to[/tex] Male
[tex]F \to[/tex] Female
The "prefer pink" event and "female" event are independent if:
[tex]P(P|F) = P(P)[/tex]
[tex]P(P|F) \to[/tex] the probability that a selected person prefers pink provided that the person is female
[tex]P(P) \to[/tex] the probability that a selected person is female
P(P| F) is calculated as:
[tex]P(P| F) = \frac{n(P\ n\ F)}{n(F)}[/tex]
i.e. the number of females who prefers pink divided by the number of females
From the table, we have:
[tex]n(P\ n\ F) = 72[/tex]
[tex]n(F) = 72 + 48 =120[/tex]
So, the probability is:
[tex]P(P| F) = \frac{72}{120}[/tex]
[tex]P(P| F) = 0.6[/tex]
[tex]P(P)[/tex] is calculated as:
[tex]P(P) = \frac{n(P)}{Total}[/tex]
i.e. the all people who prefer pink divided by total number of people
From the table, we have:
[tex]n(P) = 156 + 72 = 228[/tex]
[tex]Total = 156 + 72 + 104 + 48 = 380[/tex]
So, the probability is:
[tex]P(P) = \frac{228}{380}[/tex]
[tex]P(P) = 0.6[/tex]
Recall that:
The "prefer pink" event and "female" event are independent if:
[tex]P(P|F) = P(P)[/tex]
And we have:
[tex]P(P| F) = 0.6[/tex]
[tex]P(P) = 0.6[/tex]
Hence, the events are independent because:
[tex]P(P|F) = P(P) = 0.6[/tex]

Leon is using an area model to multiply 38×14. First, he makes a rectangle that is 38 units long and 14 units tall. Then, he breaks it into smaller parts using place value to make it easier to multiply. Use the drop-down menus to show the area of each part.
Answer:
300, 120, 80 and 32 respectively.
Step-by-step explanation:
To break it down for easy multiplication, write
38 as 30 + 8
14 as 10 + 4
Now let's multiply
(30 + 8)(10 + 4) = 300 + 120 + 80 + 32
So the areas of each part would be
300, 120, 80 and 32 respectively.
Factor 72x−18xy
Find the Factor of 72x-18xy
Answer:
4x and (1-y)
Step-by-step explanation:
4x(1-y)
this is my answer
The factors of the expression are 18x and 4-y
Given the expression 72x - 18xy
Find the factor of each term:
72x = 18 * 4 * x
18xy = 18 * x * y
Since 18x is common to both terms, hence the factored form is expressed as:
72x - 18xy = 18x (4 - y)
The factors of the expression are 18x and 4-y

The solutions are x =
and x-
Answer:
solving the equation [tex]5x^2 - 16 = 29[/tex] we get the solution: [tex]\mathbf{x=3,x=-3}[/tex]
Step-by-step explanation:
We need to solve the equation [tex]5x^2 - 16 = 29[/tex]
We need to solve the equation to find the value of x.
We can solve this equation using simple DMAS rule.
We are given:
[tex]5x^2 - 16 = 29[/tex]
Add 16 on both sides
[tex]5x^2 - 16+16 = 29+16\\5x^2=45[/tex]
Now, divide both sides by 5
[tex]\frac{5x^2}{5}=\frac{45}{5} \\x^2=9[/tex]
Now, we know that [tex]\sqrt{x^2}=\pm x[/tex]
Taking square root on both sides.
[tex]\sqrt{x^2}=\sqrt{9}\\x=\pm3[/tex]
So, we get values of x:
[tex]x=3, x=-3[/tex]
Therefore, solving the equation [tex]5x^2 - 16 = 29[/tex] we get the solution: [tex]\mathbf{x=3,x=-3}[/tex]
3. a) The dimensions of your game cover are 20 cm x 15 cm. However, you need to have a strip of
constant width around the border for labeling purposes (game console type, etc). This width will
take up 32% of your game cover's total space. What is the width of the border? Make sure to
state any values that don't make sense.
20cm×15 cm =300
32
/100 = 0.32
9514 1404 393
Answer:
1.5 cm
Step-by-step explanation:
All areas are in cm^2. For a width w, the border will have an area equal to the product of its centerline length and its width:
border area = 2((20-w) +(15-w))·w = w(70 -4w)
This area is 32% of the total cover area, so is ...
0.32(20)(15) = 96
Equating these expressions for the area gives ...
96 = 70w -4w^2
w^2 -17.5w = -24 . . . . . divide by -4
w^2 -17.5w +8.75^2 = -24 +8.75^2 . . . . . complete the square
(w -8.75)^2 = 52.5625 . . . . simplify
w -8.75 = ±√52.5625 = ±7.25
A border width only makes sense if it is between 0 and 7.5 cm, so the appropriate value for w is ...
w = 8.75 ± 7.25 . . . . . . . . . add 8.75
w = 8.75 -7.25 = 1.50 . . . . . the solution w=16 makes no sense
The border width is 1.5 cm.
