Answer:
1+1-2 its 2
Step-by-step explanation:
A holiday meal cost $12.50 a person plus a delivery fee of 30$. Which equation is right?
1. y=30+12.50x
2. y= 12.50+30
3. 12.50x=30
4. y=12.50+30x
Answer:
1. y = 12.50x + 30
Step-by-step explanation:
A holiday meal cost $12.50 a person plus a delivery fee of 30$
Let x = number of people ordering a meal and y = total cost
It cost 12.50 per person so the cost regarding the number of people that orders food can be represented by 12.50x.
There is also a $30 delivery fee.
So the total cost would (y) = 12.50x + 30
The answer would be 1. 12.50 and 30 just swapped places.
Giovanni can read 210 words per minute. If there are approximately 540 words on a page, about how many pages can he read in 3 hours? Round your answer to the nearest whole number.
462 pages
122 pages
233 pages
70 pages
She can read 70 pages in 3 hours.
What is proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
We are Given:
Giovanni can read 210 words per minute and, books contain 540 pages
So, she can read the portion of book
=210/540
= 21/54 per minutes
= 21/54 x 60
= 23.3 pages in one hour
and in 3 hours she can read
= 23.3 x 3
= 70 pages in 3 hours

A cylindrical glass holds 37683768 cubic centimeters of water. It has a height of 1212 cm. Find the area of the base of the glass.
Answer:
31092.2178
Step-by-step explanation:
Divide the volume (37683768) by the height (1212) to get the area/length x width.
37683768 / 1212 = 31092.2178

The weight of Kyle's dog increased from 29.7 pounds to 48.9 pounds in an 8 month period. What was the average weight increase per month?
Answer:
per month means we divide by the months
here is our formula
we do 48.9-29.7 to see the increase, and divide by the months to see how much per month
(48.9-29.7)/8
We get 2.4, meaning the average weight increase per month is 2.4

Question: 5/12 − 2/5= 1/60
A. The answer 1/60 is not reasonable because 5/12 is closer to 1 than to 1/2, and 2/5 is closer to 0 than to 1/2, making the difference close to 1/2.
B. The answer 1/60 is not reasonable because 5/12 is closer to 1/2 than to 1, and 2/5 is closer to 0 than to 1/2, making the difference close to 1/2.
C. The answer 1/60 is reasonable because both fractions are closer to 1/2 than they are to 0, making the difference close to 0.
D. The answer 1/60 is reasonable because both fractions are closer to 1 than they are to 1/2, making the difference close to 0.
Answer:
C
Step-by-step explanation:
It is reasonable: the answer is both reasonable and correct because 5/12 - 2/5 = 1/60. This is because using cross multiply, 5 x 5/12 = 25/60, 12 x 2/5 = 24/60. 25/60 - 24/60 = 1/60.
Both are closer to half: half out of 12 would be 6/12 and 0 would be 0/12, so 5/12 is closer to half because 5/12 is closer to 6/12 than 0/12. Half out of 5 would be 2.5/5 and 0 would be 0/5, so 2/5 is closer to half because 2/5 is closer to 2.5/5 than 0/5.
The difference is close to 0: 1/60 is very close to 0. It's only worth 0.016.

Answer: See the diagram below
==========================================================
Explanation:
She starts off finding the mean of the data. So she adds up the values to get 48+54+57+62+69 = 290, and then divides by 5 to get the mean of 290/5 = 58. That explains why there's a 58 in the first row of the second column.
---------------------
For the next step, she subtracts 58 from each data item. If the result is negative, then go with the positive version (ie apply the absolute value)
|48-58| = 10|54-58| = 4|57-58| = 1|62-58| = 4|69-58| = 11This leads to the list 10,4,1,4,11 which goes in the first slot labeled "drag and drop an item here". This is the list of distance values each item is from the mean.
---------------------
The last thing to do is find the mean of the set {10,4,1,4,11}
add: 10+4+1+4+11 = 30
divide by five: 30/5 = 6
The mean absolute deviation (MAD) is 6
This represents the average distance each data value is from the mean. The MAD tells us how spread out the data is. It's similar to the standard deviation.

Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed or left-handed students? Explain. Write your answers in simplest form.
what is the fraction for the right handed people
Answer:
Step-by-step explanation:
12% is equivalent to 12/100. This reduces to 3/25. Thus, 3/25ths of the students are left-handed. The corresponding fraction for the right handed people is (25-3)/25, or 22/25ths. There are more right-handed people (22/25ths) versus left-handed people.

What is the volume of this solid?
Most Precise Answer = Round to the nearest hundredth
Approximate Answer = Round to the nearest tenth if necessary
?
Answer:
4188.79 yd^3
Step-by-step explanation:
The formula for the volume of a sphere is ...
V = 4/3πr^3
A sphere with a diameter of 20 yards has a radius of 10 yards, so its volume is ...
V = 4/3π(10 yd)^3 = 4000π/3 yd^3 ≈ 4188.79 yd^3
Rounded to tenths, that's approximately 4188.8 yd^3.

Solve for b.
b - 7 = -20
A. b = -27
B. b = -13
C. b = 13
D. b = 27
Answer:
B. b = -13
Step-by-step explanation:
b - 7 = -20
move variables and numbers to different sides of the equal sign by adding 7 to both sides
b - 7 + 7 = -20 + 7
b = -13
