Use the fact that 4.86 : 0.45 = 10.8. Find 4.86 : 4.5 without dividing. Explain your work

Answers

Answer 1
Answer:

Answer:

Hence, the value of expression (2) is ⇒ 1.08.

Step-by-step explanation:

We are given a fact such that:

4.86 : 0.45=10.8  ------(1)

Now we are asked to find the value of the mathematical expression:

4.86 : 4.5  --------(2) without actually dividing.

We could clearly see that the numerator in both the mathematical expression is same only there is a difference in there denominator.

The denominator in second expression is just a multiplication of the denominator of first expression by 10.

Hence we divide both side of expression (1) by 10 to obtain the expression (2).

i.e. 4.86: (0.45×10)=10.8:10

i.e.  4.86: 4.5= 1.08

Hence, the value of expression (2) is 1.08.

Tommy has a pet monkey. Every day, his monkey eats 4 apples in the morning. The monkey also eats two bananas for every banana that Tommy eats.Write an equation to describe this situation where x is the number of bananas Tommy eats and y is the total number of pieces of fruit the monkey eats.

Answers

If you would like to write an equation to describe the following situation, you can do this like this:

4 apples in the morning ... 4
x ... the number of bananas Tommy eats
2 bananas for every banana that Tommy eats ... 2 * x
y ... the total number of pieces of fruit the monkey eats

The equation would be as follows: y = 4 + 2 * x.

What is the expanded form of 430,290,100

Answers

So,

When you write a number in expanded form, you separate each non-zero digit and write it according to its place value.

430,290,100

400,000,000
30,000,000

We don't put anything for the millions place because there are none.

200,000
90,000
100

Then we join each of them with a plus sign.

400,000,000 + 30,000,000 + 200,000 + 90,000 + 100
You would break each part down as if it was an addition problem....
400,000,000+30,000,000+200,000+90,000+100

Michele is 52 inches tall. Her father is 6 feet 3 inches tall. Exactly how many taller is Michele's father than Michele?

Answers

The Michele's father is 23 inches taller than Michele.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Michele is 52 inches tall.

And, Her father is 6 feet 3 inches tall.

Now,

Since, We know that;

⇒ 1 feet = 12 inches

Hence, The age of his father = 6 feet 3 inches

                                             = 6×12 + 3

                                             = 75 inches.

Hence, The length for Michele's father taller than Michele is,

⇒ 75 - 52 inches

⇒ 23 inches.

Hope this helped!

HELPP plz in. 17 thank u so much

Answers

In the table, you can see level 1 is 5 to the first power, level 2 is 5 to the second and go on. 
so in level 6 would be 5 to the sixth power
so the answer to first one is 5^6 
for the second question you should know that level 2 is 5^2 and level 6 is 5^6 so 5^6/5^2 = 5^4 is the answer :))))
I hope this is helpful
have a nice day
