Steve Fossett completed the first solo balloon circumnavigation of the world after 13.5 days. Assuming the balloon travelled along a circle of diameter 12 750 km, roughly what was the average speed of the balloon in km/h?

A) 12
B) 40
C) 75
D) 120
E) 300

Answers

Answer:

B) 40

Average speed = distance/time

Distance = 12750 km

Time = 13.5 days = 13.5*24 hours = 324 hours

Speed = 12750 km /324 h = 39.4 km/h ≈ 40 km/h

Correct option is B) 40

solve 5p-1=9 by transposing method ? please help me friends....

Answers

Transposing means doing the same thing to each side to find an unknown value.

5p - 1 = 9

Add 1 to both sides.

5p = 10

Divide both sides by 5

p = 2

Answer:

Explain how to simplify the expression -98 - 31? Using the additive inverse.

Answers

Given:

The expression is -98 - 31.

To find:

The value of the given expression using the additive inverse.

Solution:

According to the additive inverse, for any number a,

[tex]a+(-a)=0[/tex]

Using additive inverse, we have

[tex]98+(-98)=0[/tex] ...(i)

[tex]31+(-31)=0[/tex] ...(ii)

Now, using (i) and (ii), we get

[tex]98+(-98)+31+(-31)=0[/tex]

[tex](98+31)+(-98-31)=0[/tex]

[tex]129+(-98-31)=0[/tex]

Subtracting 129 from both sides, we get

[tex]-98-31=-129[/tex]

Therefore, the value of given expression is -129.

What value of x makes this equation true?
3(x + 4) = 7x - 18
O x = 5
O x = 4.5
O x = 34.5
0 x = 75.

Answers

Answer:

x = 15/2 or x = 7.5

Step-by-step explanation:

Step 1: Write equation

3(x + 4) = 7x - 18

Step 2: Solve for x

Distribute 3: 3x + 12 = 7x - 18

Subtract 3x on both sides: 12 = 4x - 18

Add 18 on both sides: 30 = 4x

Divide both sides by 4: x = 15/2 or x = 7.5

AB = 40

Step-by-step explanation:

B is between A and C so:

AB + BC = AC

7x - 2 + 3x + 1 = 59

10x - 1 = 59

+1 +1

10x = 60

grade 7. i actually already learnt this but this whole quarantine thing made me forget lolz. what are factors?
example : is 3 a factor of 372?
please answer and explain <3

Answers

Answer:

A number in a multiplication equation that makes up the total. For example,

2 x 3= 6.

2 and 3 are the factors.

Answer:

A factor is basically a number that derives from another without leaving a remainder. It sounds somewhat confusing when put into words but I'll give you some examples.

Step-by-step explanation:

in the problem you stated the answer would be yes. 3 is a factor of 372 because you can multiply 3 times another number (which in this case is 124) to get 372.

In addition, a number can have several factors. For example, these are all the factors for the number 10: 1, 2, 5, 10

notice how all these numbers multiplied by another of these same numbers on the list give you 10.

19 is not divisible by 3 so the answer is no

Answer:

no as the answer would be a decimal

Step-by-step explanation:

an easier way to know is to add up all the digits

3 + 9+0 +5+2= 19 and if that number is a multiple of 3 then it will be divisible by 3

this works for any number that should be divided by 3

example

is 2345 divisible by 3

2+3+4+5 =14 so no it is not divisible by 3

example

is 12345 divisible by 3

1+2+3+4+5 =15 so yes it is divisible by 3
