A television that has a regular price at $999 is on sale this week for $799. By what percent did the price of the television decrease? What proportion would you use to solve this problem?
A Difference over Original - 100 over x%
B $799 over $999 = x% over 100
C $200 over $999 = x% over 100
D Difference over Total = x% over 100
Answer:
C. $200 over $999 = x% over 100
Step-by-step explanation:
200/999 = 0.2002002002 about 20%
that's how much it decreases since they have a difference of 200.
f) –5 – 3( x + 1 ) = –( –4x + 1)
Answer:
x = - 1
Step-by-step explanation:
Given
- 5 - 3 (x + 1) = - (- 4x + 1) ← distribute parenthesis on both sides
- 5 - 3x - 3 = 4x - 1
- 3x - 8 = 4x - 1 ( subtract 4x from both sides )
- 7x - 8 = - 1 ( add 8 to both sides )
- 7x = 7 ( divide both sides by - 7 )
x = - 1

The chorus at an elementary school is made up on fifth and sixth graders. This year, the chorus had 12 fifth-grade girls, 9 fifth-grade boys, 14 sixth-grade girls, and 10 sixth-grade boys.
Find the following ratios:
a. The ratio of boys to girls
b. The ratio of fifth graders to sixth graders
c. The ratio of girls to the total number of students in the chorus
Answer:
A: 19:26 B:7:8 C:26:45
Step-by-step explanation:
Question A
First to find the ratio between the boys and girls you would add all of the different groups with boys and girls. This would be done by,
Boys
9+10=19
Girls
12+14=26
Now that you have the total number of boys and girls you make this ratio,
19:26
That is the final answer
Question B
For this it is very similar to the boys to girls ratio. You still add the total on each side and then form a ratio. From before you would start by adding both of the different sides which would be done by,
Fifth Graders
12+9=21
Sixth Graders
14+10=24
Now that you have the total number of both of the different grades you make this ratio,
21:24
You can simplify this by finding the lowest common factor which would be
7:8
Question C
To answer this it is very similar to the first two but instead you will find one group and all of the groups to form the ratio. Now you need to add all of the people in each of the groups.
Girls
12+14=26
All
12+9+14+10=45
Now with the total number of both you will form a ratio
26:45
This is your final answer because you cant simplify this any further

Alison paid $285 for 5similar DVDs and 9similar CDs. Janice paid $225for5similarDVDs and 5 similar CDs. How much did Suzy paid for 5 similar DVDs and six similar CDs
Answer:
$240
Step-by-step explanation:
this would be solved using simultaneous equation
let c = cost of cds
d = cost of dvds
two equatiions can be derived from the question
5d + 9c = 285 eqn 1
5d + 5c = 225 equation 2
subtract equation 2 from 1
4c = 60
c = 15
substitute for c in eqn 1
5d + 9(15) = 285
5d = 150
d = 30
5(30) + 6(15) = 240

What's the 11th term 5,15,45,135
Answer:
The 11th term is 295,245.
Step-by-step explanation:
We are given the sequence:
[tex]5, 15, 45, 135...[/tex]
And we want to find the 11th term.
First, let's determine whether this is an arithmetic sequence or a geometric sequence.
Arithmetic sequences have common differences, while geometric sequences have common ratios.
We can determine that our sequence is a geometric sequence because each subsequent term is triple the previous term: our common ratio is 3.
To find the 11th term, we can write an explicit formula for our sequence. The explicit formula for a geometric sequence is given by:
[tex]x_n=ar^{n-1}[/tex]
Where a is the initial term, r is the common ratio, and n is the nth term.
Since initial term is 5, and the common ratio is 3. Thus:
[tex]x_n=5(3)^{n-1}[/tex]
To find the 11th term, substitute 11 for n:
[tex]x_{11}=5(3)^{11-1}[/tex]
Evaluate. Thus, the 11th term is:
[tex]x_{11}=5(59049)=295245[/tex]
URGENT!!!!!!!! PLEASE HELP ASAP TIMED!!!!!!!!!!!!!!!
Step-by-step explanation:
Given that,
Perpendicular = 17 units
Hypotenuse = 25 units
We need to find the value of x.
Using Pythagoras theorem to find x.
Hypotenuse² = base²+perpendicular²
25² = x² + 17²
x = 18.3 units
So, the value of x is equal to 18.3 units. No, the sides do not form a Pythagorean triplet.
A system of equations is shown below.
x+y=5

Question 4 of 10
Which of the following is the equation of a line in slope-intercept form for a
line with slope = 5 and y-intercept at (0, -3)?
A. y=-3x + 5
B. x = 3y-5
C. y= 5x + 3
O D. y = 5x - 3
Answer:
d. y=5x-3
Slope-intercept form is y=mx+b.
m= slope
b= y intercept
so, m=5 and b= -3
Substitute with those values and then you have the equation.
How many degrees is a full circle

When having the same radius and height what fraction of a cylinder have the same volume as one cone?
Answer:
1/3
Step-by-step explanation:
volume of a cylinder = nr^2h
Volume of a cone = 1/3(nr^2h)
n = 22/7
r = radius
h = height
If the volume of a cylinder is 300, the volume of a cone = 1/3 x 300 = 100
the capacity of a cone is 1/3 that of a cylinder
If a = 20 mm, b = 12 mm, and m∠C = 80°, what is the approximate area of ABC?
Answer:
118.18 mm^2
Step-by-step explanation:
Sides a and b form angle C, so the information given is a side-angle-side (SAS) problem.
Use the formula [tex]A=\frac{1}{2}ab\sin{C}[/tex].
[tex]A=\frac{1}{2}(12)(20)\sin{80^\circ} \approx 118.18 \rm \,mm^2[/tex]
please help just tell me what they did wrong
Answer:
Step-by-step explanation:
If a point (x, y) is dilated by a scale factor of k, coordinates of the image point will be (kx, ky).
Rule that defines the dilation,
(x, y) → (kx, ky)
From the graph attached,
Coordinates of point A → (-4, 2)
Coordinates of image point A' → (-8, 4)
By the rule of dilation given,
A(-4, 2) → A'(-4k, 2k)
Since, A'(-4k, 2k) = A'(-8, 4)
Therefore, -4k = -8 ⇒ k = 2
1). Mistake in the answer → A is the preimage and A' is the image
While A has been used as image and A' as preimage.
2). Always use the rule of dilation A(x, y) → A'(kx, ky)
Here, A and A' are the preimage and image points respectively.
And 'k' is the scale factor by which point A has been dilated to form image point A'.
