Help me do this question i need help

P = 35 cm

Step-by-step explanation:

Rectangles

Being x and y the dimensions of a rectangle, the perimeter can be calculated as:

P = 2x + 2y

The smaller rectangles of the figure have a width of x cm. We don't know the value of the length, but we can see how the two smaller horizontal rectangles' widths complete the height of the vertical rectangle. Since all the rectangles are identical, then the height of each rectangle is

y = 2x

Substituting in the formula and knowing the perimeter is 21:

2x + 2(2x) = 21

6x = 21

x = 21/6 = 7/2 = 3.5

The large rectangle has a width of 2x and a length of y+x = 3x, thus the perimeter is:

P = 2(2x) + 2(3x) = 4x + 6x = 10x

Since x=3.5 cm:

P = 35 cm

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.
