Answer:
the first one is 4 and 5
Step-by-step explanation:
the second one is 45 because 15+15+15 is 45, you get 15 by the square root of 225
Answer:
1)4)5
2)45
Step-by-step explanation:
1) ✓22 = 4.69041575 which is between 4 and 5
2) The area is 225ft2 area= length * length (the only one that fits here with 225 is 15) 15*15 is 225. Now that we know the sides for perimeter:
_15__
15 |. |. 15
-------
15
The question though, asks for the perimeter which is around. So you add 15 three times for the three sides and get 45ft

The number of nickels are 41 and the number of quarters are 27.
Given that, Angela has a collection of nickels and quarters worth $8.80.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
We know that, a nickel is worth 5 cents and a quarter is worth 25 cents.
Let the number nickels be x and the number of quarters be y.
Now, 0.05x+0.25y=8.80 ----------(I)
x+y=68 ----------(II)
Substitute x=68-y in equation (I), we get
0.05(68-y)+0.25y=8.80
⇒ 3.4-0.05y+0.25y=8.80
⇒ 0.20y=8.80-3.4
⇒ 0.20y=5.4
⇒ y=5.4/0.20
⇒ y=27
Substitute y=27 in equation (II), we get
x=41
Therefore, the number of nickels are 41 and the number of quarters are 27.

What is a number line?A number line is a visual representation of the set of real numbers. A number line is a straight line on which each point corresponds to a number. The points on the line are evenly spaced, with the distance between two points representing the difference between the numbers.
The question asks how many groups of 1/3 are in 4, which is equivalent to dividing 4 by 1/3, which can be expressed as 4 ÷ 1/3
To divide a number by a fraction, we can multiply the number by the reciprocal of the fraction.
The reciprocal of a fraction is obtained by flipping the numerator and denominator. The reciprocal of 1/3 is 3/1 which is 3. The expression can therefore, be expressed as follows;
4 ÷ (1/3) = 4 × 3 = 12
The quotient of 4 ÷ (1/3) is 12, which indicates that the number of groups of 1/3 in 4 are 12
