Elaine wants to buy a couch for $899.99 if she pays $69.75 in sales tax what is the sales tax percent explain steps
Answer:
the sales tax percent is therefore: 7.75%
Step-by-step explanation:
The sales tax she paid is $69.75, for a sofa whose sale price is $899.99.
Since $69.75 is the unknown (x) percent of $899.99, then we write this statement in math terms as:
69.75 = x * 899.99
solving for x we get:
x = 69.75 / 899.99
x = 0.0775
this is the decimal form of the percent, and in order to write it as percent, we multiply it by 100:
the sales tax percent is therefore: 7.75%

What point does this line pass through?
y-2=4/5(x-3)
Answer:
(5,2)
Step-by-step explanation:
The second of two numbers is five more than twice the first. There sum is 80 . Find the numbers.
The first number = x
The second number = 5 + 2x
80 = x + 5 + 2x
Let's combine like terms.
80 = 3x + 5
Subtract 5 from both sides.
75 = 3x
Divide both sides by 3
25 = x
The first number = 25
Let's plug 25 into x for our second number's equation.
The second number = 5 + 2(25) = 55
Answer:
x = first number
y = second number
1. y = 2x +5
2. x = x
3. x + 2x + 5 = 80
4. 3x +5 = 80
5. 3x = 75
x = 25
sub back in to steps 1 and 2:
x = 25
y = 2(25) + 5
y = 55
the first number is 25, and the second number is 55.
CHECK:
80 - 25 = 55
Step-by-step explanation:
1. define your variables
2. use the question to find what each number equals
3. set them equal to 80
4. combine like terms, divide, etc. (SOLVE)
5. sub back into defined variables.
6. check it by subtracting and adding

Which statements are true about polygons? Select three options. All sides and all angles in a polygon are congruent. The sides of a polygon are segments that intersect exactly two other segments, one at each endpoint. In a polygon, all segments with a common endpoint are collinear. If all of the sides of a convex polygon are extended, none of them will contain any points that are inside the polygon. The extension of at least one side or diagonal in a concave polygon will contain a point that is inside the polygon.
Answer:
B, D, E
Step-by-step explanation:
Just took test :D
A polygon refers to a flat or two-dimensional shape which is closed and has straight sides. A polygon doesn't curved sides.
From the options given, the true statements about polygons include:
• The sides of a polygon are segments that intersect exactly two other segments, one at each endpoint.
• If all of the sides of a convex polygon are extended, none of them will contain any points that are inside the polygon.
• The extension of at least one side or diagonal in a concave polygon will contain a point that is inside the polygon.

A proportional relationship is a straight line that passes through the origin, which is (0,0). If you look at Graph 3, it looks like the line is straight, but it does not look like it will pass through (0,0). Therefore, Graph 3 does not show a proportional relationship.
Graph 4, however, does look like straight line and it does look like it will pass through (0,0). Therefore, Graph 4 does show a proportional relationship.

If m = 7x + 7, m = 4y, and m = 112
since m = 112
112 = 7x + 7
112 - 7 = 7x
105= 7x
x = 15

Which expression would represent the cost of one CD, if the total cost for three of them is $36?
36-3
3(36)
36/3
3 + 36
Given that:
Total cost for three CD = $36
Number of CD = 3
To find:
The expression that will represent the cost of one CD.
Solution:
We know that formula, to find the cost of each unit.
[tex]\text{Cost of each unit }=\dfrac{\text{Total cost}}{\text{Number of units}}[/tex]
Using this formula, we get
[tex]\text{Cost of each CD}=\dfrac{\text{Total cost for three CD}}{\text{Number of CDs}}[/tex]
[tex]\text{Cost of each CD}=\dfrac{36}{3}[/tex]
The required expression for cost of one CD is [tex]\dfrac{36}{3}[/tex].
Therefore, the correct option is C.

Answer:
25 quarters50 nickelsStep-by-step explanation:
Since there are 2 nickels for every quarter, we can group the coins into groups consisting of 1 quarter and 2 nickels. Such a group will be worth 35 cents. So, the number of groups in $8.75 is ...
$8.75/$0.35 = 25
25 groups of coins will have ...

What is the 74th term of this arithmetic sequence?
-25, -21, -17, -13,-9, -5,...
Answer:
267
Step-by-step explanation:
let's say that
f(0)=-25
so in the sequence we are adding 4
so f(1)=-25+4=-21
and f(2)=f(1)+4=-25+4+4=-25 + 4(2)
so if you continue you will notice that
f(n)=-25+4(n)
so our question is
What is the 74th term of this arithmetic sequence?
so if f(0) is our first term, the 74th will be f(73)
so we can apply our formula
f(73)=-25+4(73)
=-25+292
=267

Answer:
The value is [tex]T = 51 \ inches [/tex]
Step-by-step explanation:
From the diagram we can obtain the the height of T as follows
[tex]T = \frac{60 + 42 }{2}[/tex]
Answer:
51 inches
Step-by-step explanation:
By definition of midpoint, 42 through T + T through 60 is congruent to each other.
So, we can add 42+60 together to get the total distance. This is 102.
Next, we divide 102 by 2 because as mentioned since T is the midpoint, each "segment" is exactly 2 halves, they are congruent to each other.
102/2= 51 inches.

[tex]1^2 + 3 = 1 + 3 = 4[/tex]
[tex]2^2 + 3 = 4 + 3 = 7[/tex]

Next, is to determine the values of n;
Since [tex]n^2[/tex] is a perfect square of [tex]n[/tex], then, the values of n is 0,1,2,3,.....
Hence; Set A can be represented as: [tex]A = \{x|x\ E\ n^2 + 3, n \geq 0 \}[/tex]

The required translated figure of a triangle ABC is shown in the image attached.
Question asked to draw the image of ABC under translation by 3 units to the right and 4 units down.
What is translation?A translation is defined as a type of conversion that takes an individual point in a figure and slides it the same distance in the same direction.
Since the translation of the figure is shifting the figure through certain specified units. because of translation, there is no cause to changes to the measure of the figure. the new figure formed will be congruent to the former figure.
As per the question, we have a triangle ABC, Let applied all the translation processes to point C. coordinate of C is (-3, 1) after translation 3 units right and 4 unit down the new coordinates are (0, -3). similarly Coordinates of A and B also changed corresponding to C.
Thus, the required translated figure of a triangle ABC is shown in the image attached.

On what percent of days did it actually rain? 24.9% (Round to one decimal place as needed.) b) On what percent of days was rain predicted? nothing% (Round to one decimal place as needed.) c) What percent of the time was the forecast correct? nothing% (Round to one decimal place as needed.)
This question is incomplete, the complete question is;
Just how accurate are the weather forecasts we hear everyday? The table compares the daily forecast with a city's actual weather for a year.
FORECAST ACTUAL
Forcast Rain No Rain
Rain 28 63
No Rain 7 267
a) On what percent of days did it actually rain? 24.9% (Round to one decimal place as needed.)
b) On what percent of days was rain predicted? nothing% (Round to one decimal place as needed.)
c) What percent of the time was the forecast correct? nothing% (Round to one decimal place as needed.)
Answer:
a) the percentage of days it actually rained = 9.6%
b) percentage of days rain was predicted = 24.9%
c) percentage of days forecast was correct = 80.8%
Step-by-step explanation:
First we get the total number of days;
28 + 63 + 7 + 267 = 365 days
a)
days it actually rained = ( 28 + 7 ) = 35
now the percentage of days it actually rained
35/365 × 100 = 9.58% ≈ 9.6%
b)
days rain was predicted = ( 28 + 63 ) = 91
now percentage of days rain was predicted
91/365 × 100 = 24.93% ≈ 24.9%
c)
days forecast was correct = ( 28 + 267 ) = 295
now percentage of days forecast was correct
295/365 × 100 = 80.82% ≈ 80.8%
