Answer:

The answer to the question: What is the difference between 4 twenty fives and 3 twenty fives?

The difference is 1 twenty five that is equal to 25

Step-by-step explanation:

We need to know the difference between 4 twenty fives and 3 twenty fives, so:

$4(25)-3(25)$

We have common factor 25, so

$25(4-3)\n1(25)=25$

Answer 2

Answer: 3 twenty fives is 25 less than 4 twenty fives

If r = 9, b = 5, and g= −6, what does (r + b − g)(b + g) equal?

Answers

Answer:

-20

Step-by-step explanation:

(r + b − g)(b + g)

we have fom statement:

r = 9

b = 5

g= −6

so we have:

(r + b − g)(b + g)= (9+5-(-6))*(5+(-6))

(r + b − g)(b + g)= (14+6)*(-1)

(r + b − g)(b + g)= -20

1.228193 rounded to the nearest hundred thousandths place

Answers

The rounding number of 1.228193 rounded to the nearest hundred thousandths place will be;

⇒ 1.228190

What is rounding off?

Rounding numbers refers to changing a number's digits such that it approximates a value. The provided number is more simply represented by this value. For example, 700,000 rather than 698,869 could be used to express a town's population.

Given that;

The number is,

⇒ 1.228193

Now,

For rounded the number nearest hundred thousandths place we see the number on the place of ten thousandths place, and if the number is more than or equal to 5 then we add 1 on the ten thousandths place number and if the number is less than 5 then we cannot do anything in ten thousandths place.

Here, On the number;

The number on hundred thousandths place = 3 < 5

So, The rounding number of 2,617 rounded to the nearest hundred thousandths place will be;

⇒ 1.228190

Thus, The rounding number of 2,617 rounded to the nearest hundred thousandths place will be;

⇒ 1.228190

Answer:1.22819

Step-by-step explanation:

since 9 is in the hundred thousandths place, check the number to the right which is 3. Because 3 is below 5 we do not round up, leaving the answer to be 9. So the answer is 1.22819.

Which of the following sets of numbers is correctly orderedfrom least to greatest?
F. 4.2, V16, 45, V18
G. 4.2, V16, V18,4
H. V16, 4.2, 45, V18
I. V16, 4.2, V18,4

Answers

The correct order from least to greatest among the given sets is:

H. V16, 4.2, 45, V18

The correct order among the given sets of numbers is H: V16, 4.2, 45, V18.

Let's explore this order further:

V16: This represents the square root of 16, which is 4. So, V16 is equal to 4.

4.2: This is a decimal number and is the smallest in the set.

45: This is a whole number, larger than 4.2.

V18: This represents the square root of 18, which is approximately 4.24. Therefore, V18 is greater than 4.2 but smaller than 45.

The correct order, from least to greatest, is 4.2, V16 (4), 45, V18 (approximately 4.24).

This order is consistent with the values of these numbers.

It's important to note that square roots like V16 and V18 are essentially values between the whole numbers 4 and 5, with V18 being slightly closer to 4.

So, they fall between 4 and 4.2 in terms of magnitude, which is why they are in the middle of the ordered set.

H. V16, 4.2, 45, V18
