The height of the smaller rectangle, let us say is 5
5 x 4 = 20
(multiply height of rectangle to scale factor)
the length is 4
4 x 4 = 16
(multiply length of rectangle to scale factor)

to find larger factor, divide smaller with larger
16/20 = 1/4

scale factor should be 1/4

multiply 20 with 4

perimeter of larger should be 80

hope this helps

Jose bought a pair of sneakers, a gaming headset and a T-shirt for $77. The headset cost two times
Margarita [4]

Answer:

The cheapest item is T shirt costing $13.

Step-by-step explanation:

Let the cost of T shirt =  $ m

So, the cost of the headset = $ (2m)

and, The cost of Sneakers  = $ ( m + 25)

Total amount spent by Jose = $77

Now, According to the question:

$ m + $ (2m) + $ ( m + 25) = $77

or,  4m + 25 = 77  ⇒  4m = 77 - 25 =  52

or,  m = 52/4 = 13

⇒ The cost of one T- Shirt = m = $ 13

The cost of the headset = (2m)  =  13 x 2  = $ 26

The cost of Sneakers  = $ ( m + 25)  = 13+ 25 = $ 38

As, out of all costs, $13 is the lowest cost

Hence, the cheapest item is T shirt costing $13.

The volume of a rectangular prism is found using the formula V = l · w · h, where l is the length, w is the width, and h is the
Anastaziya [24]
There are additional details to the problem that you have left out. I have found them in other resources. The tray has to be 3 centimeters high and the length is five centimeters longer than its width. The volume of the tray is 252 cubic centimeters.

With these given, we can find the equation with the width alone as the variable:

V=lwh
252=(x+5)(x)(3)
84= x^{2} +5x

To know if it's possible for the width to be 7.5 centimeters, we just plug this as the value of x and see if it satisfies the equation:

84= (7.5)^{2} +5(7.5)
84= (7.5)^{2} +5(7.5)
84=93.75

As we can see, the equation was not satisfied therefore it is NOT possible for the width to be 7.5 centimeters.
