which polygon has an interior angle sum of 1080
Answer:
octagon which has eight sides.. (1st option )
The sum of two numbers is -5 and their difference is -1. Find the two
numbers.
Answer:
x=-3 and y=-2
Step-by-step explanation:
let the numbers be x and y
x+y=-5
x-y=-1
therefore x=-5-y
-5-y-y=-1
-2y=-1+5
-2y=4
y=-2
×=-5-(-2)
x=-5+2
x=-3
Answer: -2 and -3
Step-by-step explanation:
Number #1 = xNumber #2 = yx + y = -5
x - y = -1 -> x = y - 1
(y - 1) + y = -5
y - 1 + y = -5
2y = 1 - 5
2y = -4
y = -2
x = y - 1 = -2 - 1 = -3
$975, and there is 7 percent sales tax on the purchase.
How much is the sales tax?
Answer:
$68.25
Step-by-step explanation:
To get the sales tax, you must notice that the sales tax is 7% of 975.
That is equal to:
975 × 0.07
0.07 is equal to 7%, or [tex]\frac{7}{100}[/tex].
The answer to the equation is 68.25.
algebra 1 solve − 0.32 + 0.18 = 0.25 − 1.95
Answer:
Step-by-step explanation:
Add 0.32 and 0.18 to get 0.5.
0.5=0.25 - 1.95
subtract 1.95 from 0.25 to get —1.7.
0.5=—1.7
compare 0.5 and —1.7.

The length of a rectangle is 3
more than 5 times its width.
Find the perimeter of this
rectangle if its area is 92 m2.
[?]m
Let W = width then length = 5W + 3
Area = W(5W + 3) = 5W2 + 3W = 92
5W2 + 3W - 92 = 0 has a negative root and the positive root = 4 (by the quadratic formula)
The length = 23 and the perimeter = 2(L + W) 2 * 27 = 54
I dont know if this is right because I cant see the last part in less its like that

A square has a perimeter of 36 cm.
What is the length of each side?
Answer:
Step-by-step explanation:
The perimeter of a square has a formula P = s + s + s + s or just P = 4s where s is the length of a side. If this perimeter has a number value, we can plug it in and solve for the length of each side, like this:
36 = 4s so
s = 9 cm. And there you go!

The average human body contains about 40 L of water. What is the total amount of water contained in the 6.4 billion people in the world? Show each step in your solution. Express your answer in scientific notation.
Answer:
2.56 * 10^11 L
Step-by-step explanation:
1 body has 40 L
Thus, the amount in 6.4 billion would be;
40 * 6.4 * 10^9
= 256 * 10^9
= 2.56 * 10^2 * 10^9
= 2.56 * 10^11 L
lines b and c are parallel. no links.
Answer:
Value of x:
[tex]{ \tt{(13x + 9) + (5x + 9) = 180 \degree}} \\ { \tt{18x + 18 = 180 }} \\ { \tt{18x = 162}} \\ { \tt{x = 9}} \\ [/tex]
Angle m‹6:
[tex]{ \boxed{ \tt{m \angle6 = (5x + 9) \degree}}} \\ { \tt{m \angle6 = (5 \times 9) + 9}} \\ { \tt{m \angle6 = 54 \degree}}[/tex]
Answer:
B. 54 degrees
Step-by-step explanation:
Set up an equation that equals 180 degrees because a line is 180 degrees:
(13x+9)+(5x+9)=180
Solve for x:
x=9
Substitute 9 in 5x+9:
5(9)+9
Solve.
54
Since angle 6 is complementary, it is the same as the 7th angle.
So the answer is B, 54 degrees.
Hope this helps!

One number is 10 less than three times a second number. If their sum is 46, find the larger of the two numbers.
Answer:
32
Step-by-step explanation:
Number 1 =x
Number 2 =(3x-10)
number 1 + number 2 =46
x+(3x-10)=46
4x=56
x=14
Number 1 =x=14
Number 2=3x-10
3(14)-10
32
Number 1 (14)+Number 2 (32)=46
Two stores sell CDs in packages, as shown in the table below.
CD Prices at Store A
Number of CDs in Package

$8.40
?
$31.50
CD Prices at Store B
Number of CDs in Package
1
20
30
65
Cost
$0.60
?
$18.00
$39.00
If the rate at each store is constant, which statement correctly compares the cost of a package containing 20 CDs?
The cost at Store A is $2.00 greater than at Store B.
The cost at Store B is $2.00 greater than at Store A.
The cost at Store A is $1.00 greater than at Store B.
The cost at Store B is $1.00 greater than at Store A.
Answer:
Step-by-step explanation:
If each CD at store A costs $.70, then 20 of them will cost 20(.7) = $14.
If each CD at store B costs $.60, then 20 of them will cost 20(.6) = $12.
The correct statement is that The cost at Store A is $2.00 greater than at Store B.

Cynthia bought a bag of wafers weighing 543 grams. There are about 0.035 ounces in 1 gram. About how many ounces does the
bag of wafers weigh?
OA.
15.51
B. 0.035
C. 0.64
OD
19.01
Answer:
19.005 ounces
Step-by-step explanation:
I believe that all you have to do is mutilply the 2 numbers which is 543 and 0.035 to find the amount of ounces it weighs. So 543 × 0.035 = 19.005. The answer is 19.005 ounces. (i hope)

Answer:
4
Step-by-step explanation:
For this, you need to find the scale factor of two sides that are already given to you.
So, we will have to use the hypotenuse and one of the legs to make sure there is an accurate scale factor.
Hypotenuse:
15 / 5 = 3
Leg:
6 / 2 = 3
____________
So the scale factor is 3.
Using the leg (with the x) we need to divide 12 by the scale factor (3) to give us what x is equal to.
12 / 3 = 4
So, the answer is 4.
Sarah wants to print copies of her artwork. At the local print shop, it costs her $1 to make 5 copies and $5 to make 25 copies. How much would it cost Sarah to make 100 copies?
Answer:
$20
Step-by-step explanation:
5 copies cost $1.
25 copies cost $5.
So you have to do 100/5=$20 for 100 copies.
Answer:The answer is 20
Step-by-step explanation:
Does the graph shown below represent y as a linear function of x?
Answer: No, it is not a linear function
Explanation:
We can see that it's a function because it passes the vertical line test, but it's not linear. To be linear, it needs to be one single straight line only (instead of composed of multiple pieces of different straight lines). This graph is considered a piecewise function.
So if your teacher asked "is this a function?" then the answer would be "yes". However, the "linear" portion is what makes the final answer "no".
