Increased by 175%, the number of 24 becomes what?

Answers

Answer:

66

Step-by-step explanation:

increase the number by 175% of its value.

percentage increase = 175% × 24

new value =

24 + percentage increase =

24 + (175% × 24) =

24 + 175% × 24 =

(1 + 175%) × 24 =

(100% + 175%) × 24 =

275% × 24 =

275 ÷ 100 × 24 =

how many numbers are between k and n

Answers

Answer:

n-k-1

Step-by-step explanation:

n is bigger than k. It asks BETWEEN k and n. so, since n is bigger than k, n-k. since it says BETWEEN, you subtract 1 after that

got it?

=)

oh and the reason i am strict about BETWEEN, is because when it said between, then its discluding k and n.

If it says FROM k and n, then you both include k and n, and that would result of adding 1 instead of subtracting 1.

Ten less than a number is twice the same number​

Meaning lees 10 from 20 and multiply

Hi there!

First of all, let the unknown number be z.

Now, subtract 10:

z-10

This expression is equal to twice the same number:

z-10=2z

Solve this equation:

z-2z=10

-z=10

Divide both sides by -1 in order to get rid of the minus sign:

z=-10

Hope everything is clear.

4. Gabby ate 25 % of a whole pepperoni pizza.
Lebron ate 1/8 of the pizza.
What fraction of the pizza was left for Mohamed to eat?

Answers

Answer:

There is 5/8 left for Mohamed to eat.

Step-by-step explanation:

Let's put everything into fractions of 1/8. knowing that 25% is 1/4 or 2/8, 1/8 + 2/8= 3/8. and to find the answer, you need to subtract 3/8 from 8/8 or 1.

As a result, 5/8.

1/8 = 12.5%

12.5% + 25% = 37.5%

We need to know how much is left.

37.5% is gone, so 100% - 37.5% = 62.5%

62.5% is left for Mohamed to eat.

62.5% = 5/8.

5/8 of a pizza is left for mohamed to eat.

how many students have used all three modes of transportation? solution please​

Answers

Complete question is;

In a class of 40 students, 17 have ridden an airplane, 28 have ridden boat, 10 have ridden a train, 12 have ridden an airplane and a boat, 3 have ridden a train only, and 4 have ridden airplane only. Some students in the class have not ridden any of the three modes of transportation and an equal number have taken all three. How many students have used all three modes of transportation?

Answer:

4 students

Step-by-step explanation:

Let the number of students who used airplane be A

Let the number of students who used boat be B

Let the number of students who used train be C

Now, we are told that 17 rode plane.

Thus; A = 17

28 rode boat; B = 28

10 rode train; C = 10

12 rode airplane and boat; A ∩ B = 12

4 rode plane only; A' = 4

3 rode boat only; C' = 3

Total number of students; T = 40

Now, total number of students is represented by;

T = A - B - C - (A ∩ B) - (B ∩ C) - (C ∩ A) + (A ∩ B ∩ C)

We don't have (B ∩ C) and (C ∩ A).

Now, the can be derived from the expression of C' which is;

C' = C - (B ∩ C) - (C ∩ A)

C' = C - [(B ∩ C) + (C ∩ A)]

We are given C' = 3 and C = 10

Thus;

3 = 10 - [(B ∩ C) + (C ∩ A)]

10 - 3 = [(B ∩ C) + (C ∩ A)]

7 = [(B ∩ C) + (C ∩ A)]

Rearranging the total number of students equation, we now have;

T = A - B - C - (A ∩ B) - [(B ∩ C) + (C ∩ A)] + (A ∩ B ∩ C)

Where;

(A ∩ B ∩ C) is the number of students that used all three modes of transportation.

Thus, plugging in the relevant values;

40 = 17 + 28 + 10 - 12 - 7 + (A ∩ B ∩ C)

40 = 36 + (A ∩ B ∩ C)

(A ∩ B ∩ C) = 40 - 36

(A ∩ B ∩ C) = 4

Olga has $40 in her wallet. She has one more $5 bill than $10 bills, and two more $1 bills than $5 bills. If Olga has only three types of bills, how many bills of each denomination does she have?

Answers

Answer:

Number of $10 bills = 2

Number of $5 bills = 3

Number of $1 bills  = 5

Step-by-step explanation:

Given:

Total amount = $40

Number of $10 bills = x

Number of $5 bills = x + 1

Number of $1 bills = x + 1 + 2 = x + 3

Find:

Number of each bills

Computation:

10(x) + 5(x+1) + 1(x+3) = 40

10x + 5x + 5 + x + 3 = 40

16x = 32

x = 2

Number of $10 bills = x = 2

Number of $5 bills = x + 1 = 3

Number of $1 bills  = x + 3 = 5

Answer:

# of $10 bills = 2

# of $5 bills = 3

# of $1 bills  = 5

she drank 14 ounces of her water, she has 28 ounces left, just divide 42 by 3

Answer:

1)14oz

2)28oz

Step-by-step explanation:

1) To find the amount of water is left in the bottle you want to substract 1/3 so the first thing you want to do is find what 1/3 of 42 is. So do this: (This is also 42/3)

42*1/3=14

So we now know that 14 is 1/3 of 45 which is the first answer. To find the second answer you want to substract 14 from 42 which is 28.

So that means she has 28 oz of water left when she gets there.

Xavier is solving a problem on the whiteboard as shown.
Part A. Is Xavier's solution correct? If not, identify where he made an error.
Part B. Solve 7950 divided by 25.

Answers

Solution 1 :3/4 ÷ 1/2 = B

Solution 2 :

Quantity of trail mix with Monty = 3/4 pounds

Quantity of pounds he need to divide it into = 1/8

Number of trail mix bags Monty will have =

= 3/4 ÷ 1/8

= 3/4 × 8/1 ( division of fraction is multiplication with reciprocal )

= 24/4

We know that both 24 and 4 is divisible by 4 . Hence ,

= 24 ÷ 4 / 4 ÷ 4

= 6/1

= 6 bags

Therefore , Monty will have 6 bags of trail mix .

Solution 3 :

Quantity of food an elephant eats in 16 hours = 525 pounds

Quantity of food the elephant will eat in 1 hour = 525 ÷ 16

Quantity of food the elephant will eat in 1 hour = 32.8125 pounds = 33 pounds

Therefore , an elephant eats 33 pounds of food in 1 hour .

Solution 4 :

Number of tickets that can be purchased with $14 = 1 ticket

Number of tickets that can be purchased with $500 =

= 500 ÷ 14

= 35 tickets

Therefore , 35 tickets can be purchased with $500 .

Solution 5 :

Factors of 45 = 1 , 5 , 3, 9 , 15 and 45 .

Factors of 27 = 1 , 3 , 9 and 27 .

Their Greatest common factor = 9 .

Then , the sum of 45 and 27 can be written as :

9 ( 5 + 3 )

Therefore , Mr . Morris wrote = 9 ( 5 + 3 ) .

Solution 6 :

Total number of event flyers in a club = 4896

Total number of playerz in a club = 24

Then number of flyers each member of the club will get =

= 4896 ÷ 24

= 204

Therefore , each player will get 204 flyers .

Solution 7 :

Part A is not given .

Part B :

= 7950 ÷ 25

= 318

Therefore , 7950 ÷ 25 = 318 .
