1) Mark and Huong are selling flower bulbs for a school fundraiser. Customers can buy packages
tulip bulbs and packages of crocus bulbs. Mark sold 9 packages of tulip bulbs and 1 package of
crocus bulbs for a total of $127. Huong sold 6 packages of tulip bulbs and 6 packages of crocus
bulbs for a total of $186. Find the cost each of one package of tulips bulbs and one package of
crocus bulbs.
Answer:
Package of tulip bulbs = $12
Package of crocus = $19
Step-by-step explanation:
Let b = cost of a package of bulbs
c = cost of a crocus package
Mark: (1) 9b + c = 127 Huong: (2) 6b + 6c = 186
c = 127 - 9b 6b + 6(127 - 9b) = 186
6b + 762 - 54b = 186
- 48b = -576
b = 12
c = 127 -9(12)
c = 127 - 108 = 19
what is 4+9+8+6+5+44+88+90+78
Step-by-step explanation:
4+9+8+6+5+44+88+90+78= 332

The number 18 is decreased to 16. What is the percentage by which the number was
decreased, to the nearest tenth of a percent?
Answer:
11.1 %
Step-by-step explanation:
2/18 = 11.1%
The percentage of the number decreased is 11.1%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Initial number = 18
Final number = 16
The change in the value of the number.
= 18 - 16
= 2
The percentage decreased.
= (Change in the number / Initial number) x 100
= 2/18 x 100
= 200/18
= 11.11%
= 11.1 %
Thus,
The percentage decreased is 11.1%.

Step-by-step explanation:
a 3 inch radius circle is drawn inside a 7 in radius Circle if you throw a dart at the circles what is the probability you land inside the smaller circles
Answer:0.82
Step-by-step explanation:
The first step is to determine the areas of the inner and the bigger circles.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Considering the inner circle,
diameter = 148.4 cm
Radius = 3 inches
Area = 3.14 × 3² = 28.26 inches²
Considering the bigger circle,
Radius = 7 inches
Area = 3.14 × 7² = 153.86 inches²
The area between the bigger and inner circles is
153.86 - 28.26 = 125.6 inches²
Probability = number of favourable outcome/number of total outcome.
the probability you land inside the bigger circle but outside smaller circle is
125.6/153.86 = 0.82

Step-by-step explanation:
If your savings account has $1300 in it, and 35 is being taken away every month for 8 months, then you would multiple the months by the amount of money being taken away then subtract the amount from the total amount of money in her account. There for 'm = 1300 - 35(8)'.

The Monday after Thanksgiving is called Cyber Monday. Amazon is
offering deals on many popular items. The same drone helicopter
is normally sold for $179.99, but on Cyber Monday, Amazon will be
selling it for $125.99. What is the percent change on the drone. Round to the nearest percent
Answer:
the percentage change on the drone is 42.86%
Step-by-step explanation:
The computation of the percentage change is shown below:
Since the helicopter was sold for $179.99
But amazon would be selling it for $125.99
So, the percentage change would be
= (Sale value - sale value by amazon) ÷ ( sale value by amazon) × 100
= ($179.99 - $125.99) ÷ ($125.99) × 100
= 42.86%
Hence, the percentage change on the drone is 42.86%
Which expressions are equivalent to 3x+3(x+y)3x+3(x+y)3, x, plus, 3, left parenthesis, x, plus, y, right parenthesis
The question is incomplete. The complete question is :
Which expressions are equivalent to 3x+3(x+y)3x+3(x+y)3, x, plus, 3, left parenthesis, x, plus, y, right parenthesis ? Choose all answers that apply:
(Choice A) A 6x+3y6x+3y6, x, plus, 3, y
(Choice B) B 3(x+x+y)3(x+x+y)3, left parenthesis, x, plus, x, plus, y, right parenthesis
(Choice C) C 3xy3xy
Solution :
The equation is given as follows :
3x + 3(x+y)
We can simplify the equation in order to determine the equivalent expression.
Now applying the distributive property,
[tex]$3x+(3)(x)+(y)(3)$[/tex]
[tex]$=3x+3x+3y$[/tex]
When we add the like terms we get :
3x+3x+3y = 6x + 3y
When we factor out the term 3, we get :
3x + 3x + 3y = 3(x + x + y)
So, the expressions in options (B) and (C) are equivalent to the expression 3x + 3(x + y).

Parallelogram Properties - Angles
Answer: x=30°
Step-by-step explanation:
A parallelogram always add up to 360°.
Opposite angles like F and H are always the same, so H=150°.
150+150=300 (what angles F and H add up to)
So we can do:
360-300=60
Now we know that the angle x and E have to add up to 60 but still be the same, so x will equal 30°.
We can check this by adding up all of the sides:
150+150+30+30=360°

Suppose Lindsay’s mom invests $10,000, part at 3%, and the rest at 2.5%, in interest-bearing accounts.-10,00007.5 The totally yearly investment income (interest) is $283. How much did Lindsay’s mom invest at each rate?
Answer:
she invested 6600 at 3% and 3400 at 2.5%
Step-by-step explanation:
Simple interest = amount deposited x time x interest rate
Let the amount deposited in in the account bearing 3% interest by represented with a
Let the amount deposited in in the account bearing 2.5% interest by represented with (10,000 - a)
a x 0.03 + (10,000 - a) x 0.025 = 283
0.03a + 250 - 0,025a = 283
collect like terms
0.03a - 0.025a = 283 - 250
0.005a = 33
a = 6600
the amount deposited in the 2.5% account = 1000 - 6600 = 3400
The straight line PQ with P(1,6) and Q(-6, 1). PQ is mapped onto P'Q' by a reflection in the line = 2. What are the coordinates of P
Answer:
[tex]P' = (1,-2)[/tex]
Step-by-step explanation:
Given
[tex]P = (1.6)[/tex]
[tex]Q = (-6,1)[/tex]
Reflection over: [tex]y = 2[/tex]
Required
Determine the coordinates of P'
From the given coordinates, the y coordinates of P is 6 and the line of reflection is at y = 2
Since we are to reflect over y = 2, only the y coordinate of P will be affected.
The idea behind reflecting a point over a line is to have an equal distance between [the original point & the line of reflection] and [the new point & the line of reflection]
So, what to do is:
First, calculate the difference between the y coordinates of P and the line of reflection.
The y coordinate of P is 6 and the line of reflection is at y = 2.
So, the difference is: 6 -2 = 4
Next, subtract the calculated difference from the line of reflection to get the y coordinate of P'
y coordinate of P' = 2 - 4 = -2
Hence, the coordinate of P' is: (1,-2)
Find the area of the triangle
Answer:
C) 17.1 square units
Step-by-step explanation:
Use Heron's formula to calculate the area of the triangle:
[tex]Area = \sqrt{s(s-a)(s-b)(s-c)}[/tex] where [tex]s=\frac{a+b+c}{2}[/tex] which represents the semi-perimeter of the triangle:
[tex]s=\frac{9.9+6.1+6}{2}=11[/tex]
Therefore:
[tex]Area = \sqrt{11(11-9.9)(11-6.1)(11-6)}\\[/tex]
[tex]Area = \sqrt{11(1.1)(4.9)(5)}\\[/tex]
[tex]Area = \sqrt{296.45}\\[/tex]
[tex]Area = 17.2[/tex]
Therefore, the closest answer choice is C) 17.1 square units

A 25-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third piece is one inch more than five times the length of the first piece. Find the lengths of the pieces.
Answer:
3 inch 6 inch 16 inch 3+6+16 = 25
Step-by-step explanation:
First piesce = F
Second piece = 2F
third piece = 5F+1
F + (2F) + (5F+1) = 25
8F +1 = 25
subtract 1 om both sides
8F = 24
divide both sides by 8
F= 3
3X2= 6
3X5 +1 = 16

the probabilty that Hadi does not choose a red sock?
Answer:
Stepp-by-step explanation:
Answer: 80% or 4/5
Step-by-step explanation:
You have a total of 20 socks, and there are 4 red ones, so there's a 16/20 = 8/10 = 4/5 or 80% chance that you will not pull out a red sock.
Hope this helps!
