Answer:
20
Step-by-step explanation:
Using order of operations, we have to divide 32 by 8 first since its in parentheses, then add and subtract from left to right, so: (32/8)+27-11 = 4 + 27 - 11 = 31 - 11 = 20
Flight Distances
Chicago O'Hare is a busy international airport. The map shows the flight distance from
Chicago O'Hare to several cities. Lee conjectured the flight distance from Chicago to
Istanbul is the same as the flight distance from Chicago to Sao Paulo when the distances
are rounded to the nearest thousand.
To Beijing
5,784 miles
5,784 miles
S
6,579 miles
Chicago, Illinois
Istanbul, Turkey
Beijing, China
5,252 miles
Sao Paulo, Brazil
4. Construct Arguments Describe at least one way you could
construct an argument justifying Lee's conjecture.
Answer:
4. Given that the distance from one place to another are placed in ranges of a thousand, then the distances from Sao Paulo to Chicago Illinois which is 5,252 miles and from Chicago Illinois to Istanbul Turkey which is 5,784 miles will be in the same 5,000 kilometer distance range and both distances will taken as the same distance
The same situation can also be arrived at by rounding down both distances
Step-by-step explanation:
The given information are;
The flight distances given;
From Sao Paulo to Chicago Illinois = 5,252 miles
From Chicago Illinois to Istanbul Turkey = 5,784 miles
From Beijing China to Chicago Illinois = 6,579 miles
Lees conjectured the flight distance from Chicago to Istanbul is the same as the flight distance from Chicago Sao Paulo when the distances are rounded to the nearest thousand
Placing the distances in ranges of 1000, we have the 5,252 miles and the 5,784 miles will be in the same 5,000 to 5,999 miles range.

Select the correct answer. A baseball is hit from an initial height of 3 feet and reaches a maximum height of 403 feet. Which function could be used to model this situation, where is the height, in feet, after t seconds?
Answer:
ΔS = 1/2gt²
Step-by-step explanation:
Given
Initial height of the ball = 3 feet
Maximum height of the ball = 403 feet
To get the function that best suits the situation after t seconds, we will use the equation of motion;
ΔS = ut + 1/2gt²
ΔS is the change in height
u is the initial velocity of the body = 0m/s
g is the acceleration due to gravity = 9.81m/s²
t is the time taken for the ball to reach its maximum height.
ΔS = 403-3
ΔS = 400ft
Substituting the given values into the formula;
ΔS = ut + 1/2gt²
400 = 0 + 1/2(9.81)t²
400 = 4.905t²
t² = 400/4.905
t² = 81.55
t = √81.55
t = 9.03secs
The situation that best model the situation is ΔS = ut + 1/2gt²
ΔS = 0 + 1/2gt²
ΔS = 1/2gt²

A sports club offers an organized basketball league. A team pays $600 to join their league. In addition to paying their share of the $600, people on the team that are not members of the sports club must pay a $25 fee to play. A team pays a total of $775. How many people on the team are not club members?
Answer:
5
Step-by-step explanation:
600-775=125
25x5=125
Answer:7 team members
Step-by-step explanation:think of money... 25 cents times 4 is a dollar. So that means count from 600 by 25 until you get to 775

A factory made 357,945 baseball bats over the last 2 years. During that time, the factory made 490,867 little league baseballs and 389,839 major league baseballs. How many more baseballs than bats were manufactured during the 2 years? Liliana's answer to this question is below. Her teacher says her answer is not reasonable. Look over her work before answering (a) and (b).
Answer:
522,761 baseballs
Step-by-step explanation:
Number of baseball bats produced over the last 2 years = 357, 945
Number of little league baseballs produced over the last 2 years = 490,867
Number of major league baseballs produced over the last 2 years = 389,839
Total number of baseballs produced over the period = 490,867 + 389,839
= 880,706
Number of baseballs manufactured more than bats = 880,706 - 357945
= 522,761
There are 522,761 baseballs produced more than bats during the 2 years.
Lines c and d are intersected by line p. At the intersection of lines c and p, the bottom left angle is (3 x + 45) degrees. At the intersection of lines d and p, the uppercase left angle is 81 degrees.
What must be the value of x so that lines c and d are parallel lines cut by transversal p?
12
18
81
99
The value of x so that lines c and d are parallel lines cut by transversal p is 12
Angles and transversalsFrom the given figure, the sum of the given angles is supplementary, that is:
3x + 45 = 81
Subtract 45 from both sides
3x + 45 -45 = 81 - 45
3x = 36
x = 12
Hence the value of x so that lines c and d are parallel lines cut by transversal p is 12

Find the missing values in the ratio table. Then write the equivalent ratios.
Burgers: 3, () , 9
Hot Dogs: 5, 10, ()
Equivalent ratios are: ()
Note, the ‘()’ is indicating the missing values needing to be filled.
Answer:
60 3 948 3
Step-by-step explanation:
im just diffrent
The required ratio for the burger is 3;6:9 and the ratio for the hot dog is 5:10:15.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Let the missing ratio in Burger be x and the ratio in the Hot dogs be y,
Now,
According to the question,
3 / 5 = x / 10
x = 6
Now,
x / 10 = 9 / y
Substitute the value of x,
6 / 10 = 9 / y
y = 90 / 6
y = 15
Thus, the required ratio for the burger is 3;6:9 and the ratio for the hot dog is 5:10:15.

A and B are supplementary angles. If m A=(x-18)° and mB =(x-20),
find the measure of B
Answer:
89 degrees
Step-by-step explanation:
supplementary angles add up to 180 degrees, so we can add up A and B and make it equal to 180.
(x-18)+(x-20)=180
2x-38=180
2x=218
x=109
then, we plug in 109 for x in the mB equation.
mB=x-20
mB=109-20
mB=89 degrees
therefore, the measure of B is 89 degrees.
Answer:
B = 89
Step-by-step explanation:
Supplementary angles: A + B = 180
Simplify: x-18 +x -20 = 180
2x-38 = 180
2x = 218
x= 109
B = x-20
B = 89
Wilson paints 40% of a bookcase in 20 minutes.
How much more time will it take him to finish the bookcase?
Answer:
30 minutes
Step-by-step explanation:
The percentage rises up by 40% every 20 minutes and if we divide that in half he paints 20% in 10 minutes. Wilson needs to paint 60% more of the bookcase. 40% plus 20% is 60%. So we just add 20 with 10 to get 30 minutes.

Evaluate the following expression when x=14. X^2+5x+11
Answer:
277
Step-by-step explanation:
14^2+5(14)+11=
196+70+11=
277
Start by substituting 14 in for x everywhere that x appears in the problem.
So we have (14)² + 5(14) + 11.
Remember that PEMDAS tells you to deal
with your exponents before multiplying.
So you must square the 14 to get 196.
So we have 196 + 5(14) + 11.
Now multiply 5(14) to get 70.
So we have 196 + 70 + 11.
Now we can simply add to get 277.
