Step-by-step explanation:

$= \sqrt{80} - \sqrt{45} + 3 \sqrt{2}$

$= \sqrt{16.5} - \sqrt{9.5} + 3 \sqrt{2}$

$= 4\sqrt{5} - 3 \sqrt{5} + 3 \sqrt{2}$

$= (4 - 3) \sqrt{5} + 3 \sqrt{2}$

Sav [38]

Answer:

20 apples

Step-by-step explanation:

First, there are 320 apples that need to be split up between the siblings. We are first working with percentages. The total amount will be 100 percent. James has 45% and his brother has 30%. 45% + 30% is 75%. We subtract that from 100% and get 25%. That means that Eden gets 25% of 320 apple's. That's 320 * .25 or 320 / 4. That is 80 apples for Eden. If she gives 75% of her 80 apples, that means she gives 60 apples away. 80*.75 = 60. Eden would then only have 20 apples left. 80-60=20.

slamgirl [31]

Answer:

The number of bicycles is 19.

and the number of tricycles is 4.

Step-by-step explanation:

As we know that the number of seats in bicycles as well as in tricycles is 1.

The number of wheels in bicycles is 2

and the number of wheels in tricycles is 3.

Let the number of bicycles be x.

and the number of tricycles be y.

Thus using the given information we can make equation as,

x + y = 23

and, 2x + 3y = 50

Solving these two equations:

We get, x = 19 and y = 4

Thus the number of bicycles is 19.

and the number of tricycles is 4.

wlad13 [49]

The whole number of $\dfrac{1}{4}$ is $\boxed{0.25}.$

Further explanation:

Always use the PEDMAS rule to solve the grouping of multiplication, addition, subtraction and division.

Here, P is parenthesis, E is exponents, M is multiplication, D is division, A is addition and S is subtraction.

Given:

The number is $\dfrac{1}{4}.$

Explanation:

The whole numbers is the series of numbers that starts from zero.

The natural numbers are those numbers that start from one.

The place values are only natural numbers.

The base ten systems represent the position of a place value.

The given number is $\dfrac{1}{4}.$

Consider the number $\dfrac{1}{4}$ as $\text{A}$ .

$A = \dfrac{1}{4}$

Divide 1 by 4 to obtain the whole of $\dfrac{1}{4}.$

$\begin{aligned}\text{A}&= \frac{1}{4}\\&= 0.25\\\end{aligned}$

The decimal expansion of $\dfrac{1}{4}$ is $0.25.$

The whole number of $\dfrac{1}{4}$ is $\boxed{0.25}.$
