Answer:

25% - from 180 degrees

Step-by-step explanation:

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

Answer:

a

Step-by-step explanation:

i just needed the points

Step-by-step explanation:

9 more = + 9

the product of 5 times t = 5t

so, the answer options 1, 2 and 4 are correct

Answer: if you put 60 points onto the question it divides it by 2 for 2 different question get half of what it is so if you want each person to get 60 you need to add 120 points

Answer:

y=3x+13

Step-by-step explanation:

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.

Answer:

y=2x+6

I started with the simplist equation for the first set (0,6) of y=X+6 and then tested it out for the second set (1,8) which didn't work. I then ajusted it so it would work with the second set by doing y=2x+6. Lastly, I tested this equation with all of the points and it worked for them all.

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.

x = 23 1/3

Answer: 23

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)

This 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.

Answer:

1/b^8, 1/a^2

Step-by-step explanation:

(b^-7)^2 x b^6

= b^-14 x b^6

= b^-8

= 1/b^8 In a fraction

a^-10 x a^8

= a^-2

= 1/a^2 In a fraction

Answer:

1/b^8

1/a^2

Hola, he descubierto con qué querías ayuda! ¡Aquí hay 5 fracciones inventadas! 1/5, 1/4, 6/40, 7/8 y 21/30. ¡Espero que esto ayude! ¡Tener una gran noche! ¿Necesitas más ayuda?

Step-by-step explanation:

She can read 70 pages in 3 hours.

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

#SPJ2

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:

  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.

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

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
