The width of the smaller rectangle is 4 inches.
What is the width of a rectangle?A rectangle has four sides, but because the sides are paired, it only has two distinct dimensions. The width is traditionally the shortest of these two dimensions, but when the rectangle is shown lying on its side, the horizontal side is commonly referred to as the width.
Given:
The dimensions of the smaller rectangle are:
Length = 8 inches
Width = x inches
The dimensions of the larger rectangle are:
Length = 10 inches
Width = 5 inches
Using proportion we determine the value of x,
[tex]\frac{8}{x} = \frac{10}{5}[/tex]
Cross-multiply the terms,
8 × 5 = 10x
x = 40/10 = 4
Therefore, the width of the smaller rectangle is 4 inches.

Ratio means the quantitative relation between two amounts showing the number of times one value contains or contained in order
example 4 and 6
for example
if we have 4 men and 6 women
we can say the ratio of men to women is 4 to 6
that is 4 : 6
and ratio can also means division
for 4 and 6
= 4 / 6

How many gallons of gas will Justin need to drive 120 miles? Use a table or proportionas
As you can see, both variables are directly proportional.
Thus, the given line should have the form:
[tex]y=kx[/tex]Where k is the proportionality constant.
To find the number of gallons of gas needed to drive 120 miles, we should find k first.
Notice that we need 1 gallon of gas to drive 25 miles and 2 gallons of gas to drive 50 miles. The rate of change (k) between these variables is:
[tex]\frac{50-25}{2-1}=25\frac{gallons}{\text{mile}}[/tex]This means that it takes 25 gallons to drive each mile.
Now, we could replace:
[tex]\begin{gathered} 120=25x \\ x=\frac{120}{25}=4.8\text{gallons} \end{gathered}[/tex]Therefore, Justin needs 4.8 gallons to drive 120 miles.
Alexander Litvinenko was poisoned with 10 micrograms of the radioactive substance Polonium-210. Since radioactive decay follows a compounded continuously model, we can determine the amount of substance left in Alexander Litvinenko's body at any given time. If Polonium-210 has a decay rate of .502%, then determine the amount of Polonium-210 left in his body after 190 days. Provide 3 decimal places and units in your answer.

For j(x) = 4x − 2, find j of the quantity x plus h end quantity minus j of x all over h period
If j(x) = 4^(x - 2), the solving the given expression [j(x + h) - j(x)]/h gives;
[j(x + h) - j(x)]/h = (4^(x - 2))(4^(h) - 1)]/h
How to utilize laws of exponents?We are given the function as;
j(x) = 4^(x - 2)
Now, we want to solve the expression;
[j(x + h) - j(x)]/h
This gives us;
j(x + h) = 4^(x - 2 + h)
Thus, our expression is now;
[j(x + h) - j(x)]/h = [4^(x - 2 + h) - 4^(x - 2)]/h
Now, according to laws of exponents, we know that;
y³ × y² = y³ ⁺ ²
Thus;
4^(x - 2 + h) = 4^(x - 2) × 4^h
Therefore;
[4^(x - 2 + h) - 4^(x - 2)]/h = (4^(x - 2))(4^(h) - 1)]/h

Three cards are drawn with replacement from a standard deck of 52 cards. Find the the probability that the first card will be a spade, the second card will be a red card, and the third card will be a queen. Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
Probability is expressed as
number of favorable outcomes/number of total outcomes
In a standard deck of cards, the total number of cards is 52.
There are 13 spades in a standard deck. Thus,
probability of selecting a spade = 13/52 = 1/4
There are 26 red cards in a standard deck of cards. Since the first card was replaced, the total number of cards remains 52.
probability of selecting a red card = 26/52 = 1/2
There are 4 queens in a standard deck of cards. Since the second card was also replaced, total number of cards is still 52. Thus,
Probability of selecting a queen = 4/52 = 1/13
Thus, the probability that the first card will be a spade, the second card will be a red card, and the third card will be a queen is
1/4 x 1/2 x 1/13

The correct option regarding the minimum height reached by the toy is:
A height of -1.76 inches at 5.647 seconds.
How to find the minimum value of the function?The function for the height of the toy in the spring after x seconds is modeled as follows:
y = -cos(x) + 2cos(x)sin(x)
It is a trigonometric function, hence there is no rule to find the minimum value of the function as there is for a quadratic function, for example.
Since there is no rule, we have to sketch the graph of the function in the given domain of 0 < x < 6.
Using a graphing calculator, the graph of the function is given at the end of the answer, with minimum point at (5.647, -1.76), hence the correct option is:
A height of -1.76 inches at 5.647 seconds.

Walter is a waiter at the Towne Diner. He earns a daily wage of $50, plus tips that are equal to 15% of the total cost of the dinner he serves. What was the total cost of the dinners he served if he earned $170 on Tuesday?
Jason, this is the solution:
Walter's daily wage = $ 50
Tips = 15% of the total cost of the dinner he serves
Tuesday earnings = $ 170
Therefore,
Tips = 170 - 50
Tips = 120
For finding the cost of the dinners, we use Direct Rule of Three, as follows:
Percentage Cost
15 120
100 x
_____________________
120 * 100 = 15 * x
12,000 = 15x
Dividing by 15 at both sides:
15x/15 = 12,000/15
x = 800
The total cost of the dinners Walter serverd on Tuesday was $ 800
