Answer:
[tex]y*x=20[/tex] or [tex]y=20/x[/tex]
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form [tex]y*x=k[/tex] or [tex]y=k/x[/tex]
so
Find the value of k
For [tex](4,5)[/tex]
[tex]y*x=k[/tex] -----> [tex]5*4=k[/tex] ----> [tex]k=20[/tex]
For [tex](10,2)[/tex]
[tex]y*x=k[/tex] -----> [tex]2*10=k[/tex] ----> [tex]k=20[/tex]
The equation that represent an inverse variation is equal to
[tex]y*x=20[/tex] or [tex]y=20/x[/tex]

One kilometer equals 0.62 miles. How many kilometers equal 16 miles? Round the answer to the nearest tenth. 2.6 kilometers
9.9 kilometers
25.8 kilometers
99.2 kilometers
Answer: 25.8 kilometers
Step-by-step explanation:
Given: One kilometer = 0.62 miles
Then, [tex]1\text{ mile}=\dfrac{1}{0.62}\text{ kilometers}[/tex]
Then to find the number of kilometers in 16 miles, we need to multiply 16 to [tex]\dfrac{1}{0.62}[/tex], we get
[tex]\text{ 16 miles =}16\times\dfrac{1}{0.62}=25.806451612\approx25.8\text{ kilometers}[/tex]
Hence, 25.8 kilometers equals to 16 miles.

A carton has a length of fraction 2 and 2 over 3 feet, width of fraction 1 and 1 over 8 feet, and height of fraction 1 and 1 over 5 feet. What is the volume of the carton?
Answer:
V = 3.6 ft³Step-by-step explanation:
The formula of a volume of rectangular prism:
[tex]V=lwh[/tex]
l - length
w - width
h - height
We have
[tex]l=2\dfrac{2}{3}\ ft=\dfrac{(2)(3)+2}{3}\ ft=\dfrac{8}{3}\ dt\\\\w=1\dfrac{1}{8}\ ft=\dfrac{(1)(8)+1}{8}\ ft=\dfrac{9}{8}\ ft\\\\h=1\dfrac{1}{5}\ ft=\dfrac{(1)(5)+1}{5}\ ft=\dfrac{6}{5}\ ft[/tex]
Substitute:
[tex]V=\left(\dfrac{8}{3}\right)\left(\dfrac{9}{8}\right)\left(\dfrac{6}{5}\right)=\dfrac{432}{120}=3.6\ ft^3[/tex]
Answer:
3 3/5
Step-by-step explanation:
covert mixed fractions to improper fractions
2 2/3 becomes 8/3
1 1/8 becomes 9/8
1 1/5 become 6/5
then you multiply across will give you 432/120
since the numerator os greater than the demoninator, you have to divide 432
into 120 which then will give you 3 72/120. When you simplify the fraction the final answer is 3 3/5.

Step-by-step explanation:
A student's cell phone plan has a monthly charge of $40 for 600 minutes of use and a $0.25/minute charge for each additional minute. Last month, the student talked on the phone for 790 minutes. Which of the following is the bill for the month?
The bill for the month is $87.50, including $40 for 600 minutes and $47.50 for 190 extra minutes.
To calculate the bill for the month, we need to consider the fixed monthly charge and the additional charge for the extra minutes used beyond the 600-minute limit.
Step 1: Calculate the additional minutes used beyond the 600-minute limit:
Total minutes used - Included minutes = Extra minutes
790 minutes - 600 minutes = 190 extra minutes
Step 2: Calculate the additional charge for the extra minutes:
Extra minutes × Additional charge per minute
190 minutes × $0.25/minute = $47.50
Step 3: Add the fixed monthly charge to the additional charge for the extra minutes:
Fixed monthly charge + Additional charge for extra minutes
$40 + $47.50 = $87.50
So, the bill for the month is $87.50.

The value obtained as the power of 2 after solving the expression, (4×2⁵) ÷ (2³ × 1/16 ) will be 2⁸.
What is an integer exponent?In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
The given expression is,
(4×2⁵) ÷ (2³ × 1/16 )
Keep the base constant and add the exponents when multiplying similar bases. Maintaining the same base while multiplying the exponents will raise a base with power to another power. When dividing two bases with similar exponents, keep the exponents of the numerator and denominator constant.
= (2² × 2⁵) ÷ (2³ × 2⁻⁴ )
= (2⁷) ÷ (2⁻¹)
= 2⁸
Thus, the values obtained as the power of 2 after solving the expression, (4×2⁵) ÷ (2³ × 1/16 ) will be 2⁸.

Jessica is making a repeating pattern following the rule “triangle square circle what will be the 50th shape in the pattern?
The 50th shape in the repeating sequence of shapes (triangle, square, circle) is a square. This conclusion is reached by dividing 50 by the 3 shapes in the sequence and noting that the remainder indicates the position in the sequence.
Explanation:The problem presented is one of patterns and sequences, a common topic explored in middle school mathematics. The repeating pattern here consists of three shapes: a triangle, a square, and a circle. This sequence of three shapes continues indefinitely.
To find the 50th shape in the sequence, divide 50 by 3. You'll get 16 remainder 2. This indicates that after 16 complete cycles of the pattern (each consisting of a triangle, square, or circle), the 50th shape is the 2nd shape in the next cycle - the square. Hence the 50th shape according to Jessica's rule is a square.

Last year Milwaukee had the total of snow amounting to 92 inches . The normal fall is 52 1/4 inches . How much above normal was the snowfall last year .
The snowfall in Milwaukee last year was 39.75 inches above the normal amount, calculated by subtracting the normal annual snowfall from last year's total.
Explanation:The student's question is related to subtraction of two amounts to find the difference between the actual snowfall and the normal snowfall in Milwaukee.
To determine how much above normal last year's snowfall was, we subtract the normal snowfall amount from last year's total snowfall.
Last year's snowfall in Milwaukee = 92 inches
Normal annual snowfall = 52 1/4 inches
To find how much above normal the snowfall was, we calculate:
92 inches - 52 1/4 inches = 92 inches - 52.25 inches
This equals 39.75 inches above normal snowfall.
which least to greatest 125% 6/5 1.22
Final answer:
To compare the numbers 125%, 6/5, and 1.22, they were all converted to decimal form which revealed the least to greatest order as 1.22, 6/5, and 125%.
Explanation:
To arrange the numbers 125%, 6/5, and 1.22 from least to greatest, we first need to express all of them in the same format for an accurate comparison. Let's convert each number to a decimal:
125% as a decimal is 1.25 (since 100% is equal to 1, hence 125% is 1.25).6/5 as a decimal is 1.2 (6 divided by 5 equals 1.2).1.22 is already in decimal form.Now, we can easily compare:
1.226/5 (1.2)125% (1.25)The arrangement from least to greatest is 1.22, 6/5, 125%.

TOAD is a quadrilateral with vertices (9, 10), (18, 10), (14, 5), and (5, 5), respectively. The diagonals intersect at Point S.
Use the given information to:
a) classify the quadrilateral as a parallelogram, square, rectangle or rhombus
b) determine the intersection of the diagonals
c) use the distance formula to prove that the diagonals are bisectors of each other
⇒Plotting the Quadrilateral on two Dimensional Plane
And finding the diagonal of Quadrilateral bisect each other.
If you will look at the Quadrilateral, none of the interior angle is of 90°, so it can't be Square or Rectangle.
