Answer: No, we cannot find for its length as we can see that variables got cancelled so, we are not able to find any value for 'y'.

Step-by-step explanation:

Since we have given that

Let length of room's floor be y

Let width of a room's floor be y-5

Perimeter of room's floor be 4y+1

As we know the formula for " Perimeter of rectangle ":

Perimeter=2(Length+Width)\\\\Perimeter=2(y+y-5)\\\\4y-1=2(2y-5)\\\\4y-1=4y-20\\\\4y-4y=-20+1\\\\0\neq -19

No, we cannot find for its length as we can see that variables got cancelled so, we are not able to find any value for 'y'.

How many ways can the letters in the word balloon be arranged? 210 1,260 2,520 5,040
Lapatulllka [165]

Answer:

The number of ways this can be done is 1,260 ways

Step-by-step explanation:

In this question, we are asked to calculate the number of ways in which the letters of the word balloon can be arranged.

To do this, we take into consideration those letters that are repeated and the number of times repeated. The letters are l and o and are repeated two times each.

The number of ways = 7!/2!2! = 5040/4 = 1,260 ways

Megan works at Amazon’s warehouse. She is responsible for packing boxes into trucks for shipment. Each truck can hold 22 boxes,
Leokris [45]

Answer: Her estimate is incorrect because she has to have 25 trucks to be able to ship all her boxes.

Step-by-step explanation: Divide 539 by 22 and if there is a remainder then you need to have one more because you cant take half a truck.

539/22=24.5. Since there is a remainder, you will need 25 trucks total

The width of a rectangle measures (2.5u+9.8)(2.5u+9.8) centimeters, and its length measures (1.5u+3.9)(1.5u+3.9) centimeters. Wh
icang [17]

Solution,

We have,

Width of rectangle, b = (2.5u+9.8) cm

Length of rectangle, l = (1.5u+3.9) cm

We need to find the expression for the perimeter of the rectangle. The formula for the perimeter of a rectangle is given by:

Perimeter = 2(l+b)

P = 2[(2.5u+9.8)+(1.5u+3.9)]

Collecting like terms

P = 2[(2.5u+1.5u)+(9.8+3.9)]

P=2(4u+13.7)

⇒ P = 8u+27.4

So, the expression for the perimeter of the rectangle is (8u+27.4) cm.
