Answer:

1. 32÷2, 64÷4

2. 16

Step-by-step explanation:

Expression 1:

32÷2=16, and 64÷4=16.

Expression 2:

Change the divisor 2.3 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

368 ÷ 23 = 16

and therefore:

36.8 ÷ 2.3 = 16

Both calculated to 0 decimal places.

Kia thinks that every number has at least two factors. Which explains whether Kia is correct?
elena-14-01-66 [18.8K]

Solution:

Yes , what mathematics say that every real number has at least two factors apart from number 1 and -1.

The number zero has infinite factors.

The number 1 and -1 which is neither prime nor composite has only 1 factor i.e itself.

Prime integers  has only two factors one and itself.

Non prime integers has more than two factors.

But when you say a number apart from natural, whole and integers it includes rational ,and irrational and when we combine them The set is called Real number. .So, Yes this statement is true for rational and irrational also.

So, yes Kia is not absolutely true, but if she has written the statement in this form:  Apart from 1 and -1 , every number has at least two factors then it would have been a true statement.

If the streets of a city are straight lines and the intersections are points, show how Principle 2 and Principle 3 might be illu
Naily [24]

Step-by-step explanation:

Principle 2 states that between any two points, only one straight line can be drawn.

And according to principle 3 two straight lines interacts at one point only.

Thus this can be well illustrated by two straight lines which are represented by the streets of a city and these two streets intersects at a point.

I need help with question 2. Anything is appreciated:)
Ivahew [28]

1x + 8 = 10 + 0.5x

1x - 0.5x = .5x

.5x + 8 = 10

10 - 8 = 2

2/.5 = 4

Therefore, it will take 4 years for the two trees to have grown to the same height.
