The sum of three consecutive numbers is 84. what is the largest of these numbers? 26 27 28 29

Answers

Answer 1
Answer:

Answer:

The largest number is 29.

Step-by-step explanation:

Let the numbers be = x , x+1 , x+2

As given, their sum is 84, we can write as:

x+x+1+x+2=84

=> 3x+3=84

=> 3x=84-3

=> 3x=81

x = 27

So, x+1= 27+1=28

And x+2 = 27+2=29

Hence, the largest number is 29.

Answer 2
Answer: The largest of the three consecutive numbers whose sum equals to 84 is 29.

Y=3x 2x+y=15
Can you please help with this? It's confusing. It's soling systems of equations by substitution

Answers

so you subtitute y=3x into
2x+y=15
so
2x+(3x)=15
add like terms
5x=15
divide both sides by 5
x=3

subtitute x=3 into first equation (y=3x)
y=3(3)
y=9
it's simple jus plug in 3x into Y and u will have 2x+3x=15

7. Numericals(a) A box has length 50 cm, breadth 20 cm and height 10 cm, then find
(i) its surface area of base;
(ii) its volume
(1000 cm², 100000 cm3)​

Answers

Answer:

i = 1000cm2

ii = 100000cm3

Step-by-step explanation:

for q i

surface area of base = l* b

= 50* 20

1000cm^2

for q 2

volume l*b*h

= 50*20*10

= 100000cm^3

Which fraction is equal to 0.4 repeating

Answers

The fraction equal to 0.4 repeating is 4/9.

The fraction equal to 0.4 repeating can be determined by converting the repeating decimal into a fraction form.

We denote the repeating decimal as x. To eliminate the repeating part, we multiply both sides of the equation by a power of 10 that is equal to the number of repeating digits.

In this case, multiplying by 10 will be enough.

10x = 4.44444...

Now, subtracting x from both sides, we have:

10x - x = (4.44444...) - (0.44444...)

9x = 4

Dividing both sides by 9:

x = 4/9

Therefore, the required fraction is 4/9.

The third term in a sequence is 25. The fifth term is 225. What are the possible values of the 4th term of the sequence if it is arithmetic? If it is geometric?

Answers

Answer:

if it is arithmetic, ach item us increase linearly. The general term is - 175+100(n-1)

where n is the number of term.

the 4th term is 125

if it is geometic, each item us increased exponetially. T he general term is 25/9 x 3^(n-1)

where n is the number of term

the 4th term is 75

Which of the following sets represents M∪N?{2, 5, 8}
{4, 7}
{3, 4, 6, 7, 9}
{3, 6, 9}

Answers

Answer : {3, 4, 6, 7, 9}

To find the set that represents M∪N, we take union of M  and N

For union of M and N, we consider all the numbers inside the circles M and N.

WE have 9 and 3 inside M. Also we have 6 inside N. 4 and 7 are in the intersection of M and N. So we consider 4 and 7 as well

M∪N = 9,3,6,4 and 7

{3, 4, 6, 7, 9} is the answer.

How many feet are traveled by a person riding once around the merry -go-round ? Clare says, " The radius of the merry -go-round is about 4 feet , so the distance around the edge is about 8π feet. " Andre says , " The diameter of the merry-go-round is about 4 feet, so the distance around the edge is about 4π feet."

Answers

Answer:

The actual formula for the circumference is 2rpi. But the radius multiplied by 2 is the diameter. They are both right. Plug it the values in the formul and you will see. Sry if it doesn't make sense

Step-by-step explanation:

Final answer:

To find the distance traveled by a person riding once around the merry-go-round, you need to calculate the circumference. The correct calculation is based on the radius, which is 4 feet. The distance around the edge is about 8π feet.

Explanation:

To find the distance traveled by a person riding once around the merry-go-round, we need to calculate the circumference. The circumference of a circle can be calculated using either its radius or diameter. Clare's statement is correct: the radius of the merry-go-round is 4 feet, so the distance around the edge is about 8π feet.

Using the diameter of the merry-go-round, Andre's statement is incorrect. The formula for the circumference using the diameter is C = π * d, where d is the diameter. In this case, the distance around the edge is about 8π feet, not 4π feet as Andre suggested.
