The required number of tiles will be 34 covering the length of the entryway.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
We have been given that the tiles are each 2/9 feet long, and the entryway is 7 1/2 feet long.
We have to determine the number of tiles will he need to buy in order to cover the length of the entryway.
According to the given question, the required solution would be as:
So the number of tiles covering the length of the entryway will be
⇒ 7 1/2 ÷ (2/9)
⇒ 15/2 ÷ (2/9)
⇒ 15/2 / (2/9)
Reciprocal the term in the denominator
⇒ (15/2) x (9/2)
Apply the multiplication operation,
⇒ 135/4
Apply the division operation,
⇒ 34
Thus, the required number of tiles will be 34 covering the length of the entryway.

the perimeter of a rectangle is at least 74 cm the length of a rectangle is two more than four times the width of a rectangle what are the minimum dimensions of the rectangle
Answer:
2W+2L=perimeter=74
Step-by-step explanation:
2W=74-2L
2(2W)+2(L/2)=76
substitute 74 - 2L for 2W in the last equation to solve for L. Put that value in the first equation to find W. Check by putting both values into the last equation.
Given that 3^-n=0.2
Find the value of (3^n)^2
Step-by-step explanation:
3^-n=0.2
1/3^n=0.2
1=0.2(3^n)
3^n=1/0.2
3^n=5
(3^n)²=5²
(3^n)²=25
The value of the given expression (3^n)^2 is; 25.
Evaluating the value of an expressionFrom the task content, it follows that;
3^-n=0.21/3^n=1/5On this note; it follows that; 3^n = 5.
Consequently, the value of the expression (3^n)^2 is; (5)²
The value of the expression; (3^n)^2 is; 25.

A river 3m deep and 40 m wide is flowing at the rate 2km /h . how much water will fall into the sea in a minute.
Answer:
Area of river = depth × width
=3×40
[tex] = 120 {m}^{2} [/tex]
amount of water that falls into the sea ⇒
Area of river × flow rate
[tex]120 {m}^{2} \times 2 \: \frac{km}{hr} [/tex]
[tex]120 \times \frac{2 \times 1000 {m}^{2} }{(60)min} [/tex]
[tex]4000 \: \frac{ {m}^{3} }{min} [/tex]
:. [tex] {4000m}^{3} [/tex] of water falls into the sea per min.
So, [tex] {4000m}^{3} [/tex]
= 4000 × 1000 litres
= 4000000 litres
So, in 1 minute, water will fall into the sea is 4000000 litres.

A cube has a surface area of 126 feet. What is the area of one face?
Answer:
21 square feet
Step-by-step explanation:
A cube has 6 faces, therefore 126/6 = 21 sq/ft the area of 1 face
The area of one face of a cube is 21 feet.
What is the surface area of cube?Surface area of cube is the sum of areas of all the faces of cube, that covers it.
The formula for surface area is equal to six times of square of length of the sides of cube.
A cube has a surface area of 126 feet.
The area of one face is given by;
[tex]\rm Area \ of \ one \ face=\dfrac{Surface \ area}{Total \ number \ of \ faces}\\\\ Area \ of \ one \ face=\dfrac{126}{6}\\\\ Area \ of \ one \ face=21[/tex]
Hence, the area of one face of a cube is 21 feet.

There are 10 doors to a coliseum. In how many ways can a person go in and out if one can enter any door but leave using another door? Use permutation formula (P(n,r)) to solve.
Answer:
90 is the answer
Step-by-step explanation:
P(10,2) = [tex]\frac{10!}{(10-2)!}[/tex] = [tex]\frac{10!}{8!}[/tex] = [tex]\frac{10x9x8!}{8!}[/tex]
10x9
=90
The number of ways should be 90.
Calculation of no of ways:Since There are 10 doors to a coliseum.
So, here we used the permutation
[tex]= \frac{10!}{(10!-2!)}\\\\ = \frac{10!}{8!} \\\\= \frac{10\times 9\times 8!}{8!} \\\\= 10\times 9[/tex]
