Which polygon has an interior angle sum of 1280º?
Answers
Answer:
3rd shape as it hase 9 sides
Step-by-step explanation:
1260/ 180 =7
7+2 = 9 sided shape
The polygon with 9 sides has an interior angle sum of 1280º.
Hence, option c is true.
We have to give that,
In a polygon an interior angle sum of 1280º.
We know that,
The formula for calculating the sum of interior angles is,
( n − 2 ) × 180°
where n is the number of sides.
Here, an interior angle sum of 1280º
Hence,
(n - 2) × 180° = 1280°
Divide both sides by 180°
(n - 2) = 1280/180
n - 2 = 7
n = 7 + 2
n = 9
So, The polygon with 9 sides has an interior angle sum of 1280º.

We need to find how much salt is left in the container.
How do subtract decimals?To subtract decimals, write the numbers in a column, and make sure that the decimal points are aligned. To keep the decimal point in your difference, place a decimal point directly below the decimal points in the subtrends. Align the decimal point in the sum with the decimal point in the subtrends, and add a zero if necessary.
Now, 0.97-0.56=0.41 grams
Hence, the salt left in the container is 0.41 grams.

What is the value of x?
Answers
Answer:
60
Step-by-step explanation:
180-120= 60
a line is 180 degrees and x is congruent to the angle on the right of 120, meaning if you find the missing angle to that angle(the one next to 120) then you'd get the answer. Knowing the line it 180 and 120 is supplementary to x. x=60.

find the solution
Answers
Answer:
22/15=x
Step-by-step explanation:
Well first off we have to do the stuff in the parentheses-
3x(3+7)-42=2
9x+21x-42=2 Now we have to get x by itself
+42 +42
9x+21x=44 Now add the like terms
30x=44 Divide by 30
/30 /30 30 chancels out
44/30 Simplify
22/15=x
Do the parenthesis first, 3+7=10, then do the exponent and get 256,multiply 3 times 10 and get 30, do 256 divided by 2 and get 128, finally do 30-128 to get 98.

Answers
Answer:
64 (2) ^ n-1
Step-by-step explanation:
The rule for the given geometric sequence is 64(2)ⁿ⁻¹
What is a geometric sequence?A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value.
Its general term is arⁿ⁻¹. The value r is called the common ratio.
Given is a geometric sequence, 64, 128, 256, 512....., we need to find the rule for the sequence,
The general formula for geometric sequence, = arⁿ⁻¹
Finding the common ratio, r = aₙ₊₁ / a₁
r = 128 / 64 = 2
Therefore, we can write, the rule as,
aₙ = 64(2)ⁿ⁻¹
Hence, the rule for the given geometric sequence is 64(2)ⁿ⁻¹

parking at each parking lot is shown below.
Day 1 - $5.00 for the first hour plus $1.50 for every additional hour
Day 2 - $2.50 for the first hour plus $1.50 for every additional hour
What is the total amount Jerome spent to park his car at the parking lots after the two days?
A.$10.50
B.$13.50
C.$16.50
D.$19.50
ANSWER AND HAPPY NEW YEAR!!
Answers
Answer:
C, or $16.50
Step-by-step explanation:
First of all, I added the prices of the first hours of both days. $5.00 + $2.50 = $7.50. Then, for every hour, the price for parking is $1.50. So, the easier way of doing this is adding the prices of both days together. $1.50 + $1.50 = $3.00. So, she parked for a three hours each in parking lots 1 and two. So, that's 3 times $3 which is $9. $9.00 + $7.50 = $16.50.
