$15 for 5 pairs of socks; $25 for 10 pairs of socks Determine if each pair of ratios or rates are equivalent. Explain your reasoning.
Answer:
These ratios are not equivalent.
Step-by-step explanation:
If you get 5 pairs of socks for $15, that means that each pair of socks are $3. If you buy 10 pairs of socks for $25, you are spending $12.50 for each pair. If you double the 5 pairs of socks for 10 pairs of socks, you will be spending $30 because you have to add another $15.
So between 10 pairs of socks for $30 (5 pairs of socks for $15) and 10 pairs of socks for $25, you will be spending more on the 5 pairs of socks.
You are spending more money on the 5 pairs of socks for $15.
Make h the subject of the formula:
d=√(3h/2)
Answer:
Do you mean d = √(3h/2)?
Square both sides:
d² = √(3h/2)²
d² = 3h/2
Then, multiply both sides by 2/3 to obtain:
h = 2d²/3

Joan is 4 feet 2 inches tall. There are 2.54 centimeters in 1 inch. What is Joan’s height in centimeters?
Answer:
Thus the answer is 127
Step-by-step explanation:
4 feet = 48 inches. 2.54 = 1 inch.
It is found that Joan's height is 127 centimetres.
What is the fundamental principle of multiplication?If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that Joan is 4 feet 2 inches tall and we need to change to centimeters .
First we change her height to inches;
1 Foot = 12 Inches
Therefore, 4 Feet = 4 x 12 = 48 inches
The Total height in inches =48 inches + 2 Inches = 50 inches
Now, we have gotten her height in inches, change to centimetres.
We have that;
1 inch =2.54 centimeters
50inches = 50 x 2.54 cm
=127 centmeters.
Hence, Joan's height is 127 centimetres.

The estimate of the square roots and cube roots of numbers can be found by an iterative process;
The Pythagoras's Theorem, PT, and its Converse: Estimating Square Roots
The steps to estimating square roots are;1. The perfect squares that are close to the number for which the square root is sought are listed
Example, to find the square root of 5, we have;
2², 5, 6, 7, 8, 3²
Therefore, the perfect square close to 5 are those of 2 and 3
The number 5 is then divided by the root of the number with closest perfect square, which is √4 = 2
Therefore, we have;
[tex]\dfrac{5}{2} = 2.5[/tex]The average of the result of the division and the divisor is then found as follows;
[tex]\dfrac{2 + 2.5}{2} = 2.25[/tex]The required number is then divided again by the average, 2.25, again, to get;
[tex]\dfrac{5}{2.25} = 2.\overline 2[/tex]The average of the new quotient and the divisor is found again as follows;
[tex]\dfrac{2.25 + 2.\overline 2}{2} = 2.36\overline 1[/tex]Repeat dividing the required number by the average again as follows;
[tex]\dfrac{5}{2.36 \overline 1} = 2.23602484472[/tex]The average is found again as 2.23606797792
Dividing 5 gives 2.23606797708
Therefore;
2.236067978 is a good estimate of √5 approximation2. To estimate a cube root of a number, the closest, numbers with a perfect cube are listed
To estimate the cube root of 9, the closest perfect cubes are 8 and 27
We have;
∛8 < ∛9 < ∛27
2 < ∛9 < 3
Given that we have;
The difference between 9 and 8 = 1
The difference between 9 and 27 = 18
Therefore, the cube root of 9, ∛9 ≈ 2
For more accurate value, we have
[tex]{} \hspace {8pt}2.08\\3| \overline {9.000 000}\\ {} \hspace {-3pt} -8\\ {} \hspace {8pt} 1 \ 000 \ 0[/tex]
Where, the 2 in the quotient is given from the closest perfect cube to 9;
2³ = 8 < 9
The 8 is given from 2³ = 8
The 1 is given from 9 - 8 = 1
The 000, is obtained by bringing down 000, from the dividend
Next; Multiply 300 by 2² to get 1,200
1,200 is larger than 1,000, which is the remainder, therefore, a decimal point and 0 is added to the quotient, and a zero is added to the remainder to give 10,000, from which we have;
[tex]\dfrac{10,000}{300 \times 2^2} = 8\frac{1}{3}[/tex]
The quotient, 8 is added to the quotient line after the zero, to get;
∛9 ≈ 2.08

The graph shows the number of quarts picked and the amount of money the customer paid.
Another customer pays $8.75 for the strawberries she picks. What point (n, a) on the graph represents this?
Answer:
$3.50 for 1 quart
Step-by-step explanation:
Point (n, a) on the graph represents the number of quarts and the Amount paid(in $).
What is the importance of graphs in our daily life?Graphs are a popular tool for visually illuminating data relationships. A graph serves the objective of presenting data that are either too many or complex to be fully expressed in the text while taking up less room.
Given, The graph shows the number of quarts picked and the amount of money the customer paid. Another customer pays $8.75 for the strawberries she picks.
Slope of the given graph = y₂ - y₁ / x₂ - x₁
Slope of the given graph = 3.5-0 /1-0 = 3.5
As the Graph is passing through the origin point
Hence, the equation of the line will be y = mx
Where slope(m) = 3.5
thus the equation of the given graph y = 3.5 x
For another customer given, y = 8.75
Hence x = 8.75/3.5
x = 2.5
Coordinates over the graph will be(2.5, 8.75)
Therefore, The number of quarts and the amount paid (in dollars) are represented by the graph's points (n, a).
