The area of a rectangle is 72 sq units. One side length is 9 units. What is the other side length
Answers
Based on the area of the rectangle and the length of one side, the length of the other side is 8 units
The area of a rectangle is calculated as:
Area = Length x Width
The length is already given so the width is:
72 = 9 x Width
Width = 72 / 9
Width = 8 units
In conclusion, the other side length is 8 units.

Answer:
The length of other side of rectangle is 8 unit.
Step-by-step explanation:
Given :
[tex]\pink\star[/tex] Area of rectangle = 72 sq units[tex]\pink\star[/tex] Lenght of rectangle = 9 unitsTo Find :
[tex]\pink\star[/tex] Breadth of rectangleUsing Formula :
[tex]\star{\small{\underline{\boxed{\sf{\purple{Area_{(Rectangle)} = l \times b}}}}}}[/tex]
[tex]\blue\star[/tex] l = length [tex]\blue\star[/tex] b = breadthSolution :
Substituting all the given values in the formula to find breadth of rectangle :
[tex]{\dashrightarrow{\sf{Area_{(Rectangle)} = l \times b}}}[/tex]
[tex]{\dashrightarrow{\sf{72= 9 \times b}}}[/tex]
[tex]{\dashrightarrow{\sf{b = 72\div 9}}}[/tex]
[tex]{\dashrightarrow{\sf{b = \dfrac{72}{9}}}}[/tex]
[tex]{\dashrightarrow{\sf{b = \cancel{\dfrac{72}{9}}}}}[/tex]
[tex]{\dashrightarrow{\sf{b = 8 \: unit}}}[/tex]

A pencil costs $0.25 more than an eraser. If the cost of eight pencils is $6.80, what is the cost of one eraser?
Answers
Answer:
A single pencil costs $0.85 and a single eraser costs $0.60
Answer: The cost of one eraser is $0.6
Step-by-step explanation:
When solving this problem, it's best to set up a system of equations. Let pencil = p and eraser = e.
p = $0.25 + e
8p = $6.80
Now, we can use the second equation to solve for p by dividing both sides by 8. 6.8/8 = 0.85. Therefore, p = $0.85.
Then, use the value of p to find e by plugging the value of p we just found back into the first equation we wrote. Doing so, we get $0.85 = $0.25 + e. To solve for e, we must subtract 0.25 from both sides, giving use 0.85-0.25 = 0.6
Therefore e = $0.6, so the cost of one eraser is $0.6 or 60 cents.

Step-by-step explanation:
In algebra the numbers are multiplied with the numbers and the variables are multiplied with the variables.
In this question we would multiply x with b and 4 with 4 .
Multiplying x with b would give xb and 4 with 4 gives 16
So the answer will be 16xb

Find the inverse of “f” algebraically, please!
Answers
Answer: [tex]f^{-1}(x) = -\sqrt{36-x^2}[/tex]
====================================================
Here are the steps to find the inverse
[tex]f(x) = \sqrt{36-x^2}\\\\y = \sqrt{36-x^2}\\\\x = \sqrt{36-y^2} \ \text{ swap x and y; solve for y}\\\\x^2 = 36-y^2\\\\x^2+y^2 = 36\\\\y^2 = 36-x^2\\\\y = \sqrt{36-x^2}\\\\f^{-1}(x) = \sqrt{36-x^2}\\\\[/tex]
Now this would be the answer if our original domain was [tex]0 \le x \le 6[/tex]
However, that's not the case and instead our domain is [tex]-6 \le x \le 0[/tex]
Reflecting any (x,y) point in this domain restriction, over the the line y = x, will have us land on a point with a negative y value. This is because the inverse will swap the x and y values.
Therefore, the inverse function must ultimately be negative.
Currently [tex]f^{-1}(x) = \sqrt{36-x^2}[/tex] is positive since the result of any square root is never negative.
To fix this, we stick a negative out front to get the final answer being [tex]f^{-1}(x) = -\sqrt{36-x^2}[/tex]

Bart needs 18 pieces of string 35 inch in length. He cut a 825inch piece of string into pieces that are 35 of an inch long. How many more pieces of string does he need? Show your work.
Answers
Answer:
He needs 4 more pieces
Step-by-step explanation:
Here, we want to know the number of more string pieces that are needed
Firstly, we need to the number of string pieces obtained from the 8 2/5 inch piece
we divide 8 2/5 by 3/5
That will be;
42/5 * 5/3 = 14
So what he will get is 14 pieces from the 8 2/5 inch
The number of pieces needed is thus;
18-14 = 4

We automatically know becuase theres. Right angle (90) and a 60 degree angle
now the formula is the smallest side is (n) {I’m using N becuase theres already an X) or in this case, 6
The hypotenuse, the one directly above the 2nd biggest side, or the diagnoal side is 2n or (12). Now we know what X is in this situation which is 12. So that narrows it to 2 answers
Now the side on the bottom of the hypotenuse, the second biggest side is used in the formula N[tex]\sqrt{3}[/tex]. So we know what N is in the beginning, 6 so we just plug that in and well get C. Attached is a photo on q 30, 60, 90 special right triangle
I need help determineing the next number.?!
Answers
Answer:
The next number is -12 ⇒ B
Step-by-step explanation:
Let us solve the question
∵ The pattern is 2,916, -972, 324, -108, 36, ....
→ All the given numbers are divisible by 3 because the sum of
the digits of each number can divide by 3
2+9+1+6 = 18 → multiple of 39+7+2 = 18 → multiple of 33+2+4 = 9 → multiple of 31+0+8 = 9 → multiple of 33+6 = 9 → multiple of 3∵ The pattern has positive and negative numbers
∴ Each next term = the previous term ÷ -3
→ Let us do that to find the missing number
∵ 2916 ÷ -3 = -972
∵ -972 ÷ -3 = 324
∵ 324 ÷ -3 = -108
∵ -108 ÷ -3 = 36
→ Find the next number by divide 36 by -3
∵ 36 ÷ -3 = -12
∴ The next number is -12
