Answer: 180
The sum of the angles in a rectangle is given by (n-2)180 where n is the number of sides of the polygon and n is greater than or equal to 3. For a rectangle, n=4 thus sum of angles is (4–2)180 = 360 degrees. Each interior angle is 360/4 = 90 degrees.
Answer:
180⁰is the interior angle of a rectangle
After 2 hours, the air temperature had risen 7° f. How long will it take at this rate for the temperature to rise an additional 13°f?
Answer:
21 hours
Step-by-step explanation:
After 2 hours the temperature has risen to 7°f
The time taken to rise to an additional 13°f can be calculated as follows
1 hour takes 3.5°f
13°f = 3.5×6
= 21 hours
Hence it would take 21 hours

seven people sit in a circle.How many ways can this be done if two people A and B sit together
Step-by-step explanation:
Suppose the persons are a, b, c, d, e, f and g.
Let us also assume that a and b always sit together.
Let us then put the remaining 5 persons in a circular arrangement. It can be done in (5–1)! = 4! = 24 ways. Now, the pair (a,b) can be placed between any two persons already placed in circular order. There are 5 such gaps. Finally the pair (a,b) can be placed in two ways viz. (a,b) and (b,a).
So, total number of ways a group of 7 persons can be seated around a circular table where 2 specified persons always sit together is 24 X 2 X 5 = 240
A school cafeteria offers three lunch options on Mondays: spaghetti, sub sandwiches, or salad bar. The following two-way frequency table shows the number of each lunch option ordered on a given.
What percentage of teachers ordered the salad bar?
OA. 19.48%
B. 10.21%
C. 2.38%
D. 65.22%
Answer: 65.22%
Step-by-step explanation: 15 is more than half of 23 which means it can’t be the other options because the others aren’t more than half.
65.22 % of teachers ordered the salad bar
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
According to the question
A school cafeteria offers three lunch options on Mondays:
Spaghetti, sub sandwiches, or salad bar.
Percentage of teachers ordered the salad bar
Total number of teachers = 23
Total number of teachers ordered the salad bar = 15
= [tex]\frac{15}{23}[/tex]
= 0.6522
= 65.22%
Thus, 65.22 % of teachers ordered the salad bar

Step-by-step explanation:
Hailey invested $2,000 in an account paying an interest rate of 2\tfrac{3}{8}2 8 3 % compounded continuously. Sophie invested $2,000 in an account paying an interest rate of 2\tfrac{7}{8}2 8 7 % compounded daily. To the nearest hundredth of a year, how much longer would it take for Hailey's money to double than for Sophie's money to double?
Answer:
5.08 years
Step-by-step explanation:
We are to solve for time using compound interest formulas
For Hailey
Principal = $200
Amount = Double of Principal = $4000
Rate = 2 3/8% = 2.375.
Time = ?
Hence,
First, convert R as a percent to r as a decimal
r = R/100
r = 2.375/100
r = 0.02375 per year,
Then, solve the equation for t
t = ln(A/P) / r
t = ln(4,000.00/2,000.00) / 0.02375
t = 29.185 years
≈ 29.19 years
For Sophie
Principal = $200
Amount = Double of Principal = $4000
Rate = 2 7/8% = 2.875
Time = ?
First, convert R as a percent to r as a decimal
r = R/100
r = 2.875/100
r = 0.02875 per year,
Then, solve the equation for t
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(4,000.00/2,000.00) / ( 365 × [ln(1 + 0.02875/365)] )
t = ln(4,000.00/2,000.00) / ( 365 × [ln(1 + 7.8767E-5)] )
t = 24.11 years
How much longer would it take for Hailey's money to double than for Sophie's money to double?
For Hailey it takes 29.19 years
For Sophie it takes 24.11 years
We find the difference
= 29.19 - 24.11
= 5.08 years
Therefore, it would take 5.08 years for Hailey's money to double than Sophie

Which Equation best matches the graph shown below?
Answer:
.2(x+1)(x+5)
Step-by-step explanation:
Well first lets start with the x intercepts which are -1 and negative 5 so the equation must be either -0.2(x+1)(x+5) or .2(x+1)(x+5)
Notice how the graph is going upwards this means the number in front of the equation -.2 or .2 must be positive making .2(x+1)(x+5) this is because if .2 was negative the graph would be going downwards
