Please can someone help me work out the missing length​
Otrada [13]
Vol=area x Height

length= 3
breadth= X
Height = 2

area must = half of 42 because to get the volume of 42cm cubed, you had to times the area by 2 so

42 devided by 2 is 21 so to find the length you myst do 21 devided by 3 which is 7

so the missing length is 7cm

A school choir needs to make t-shirts for its 75 members. A printing company charges $2 per shirt, plus a $50 fee for each color
svlad2 [7]

Let's begin by listing out the given information:

total number of members = 75

printing charge = $2 per shirt

colour print for each shirt = $50 fee for each color to be printed on the shirts

Let the number of t-shirts be represented as n

Let the number of colors on the shirts be represented as x

Let the total cost of the order be represented as C

Every member must have a t-shirt means

total number of members * printing charge + (colour print for each shirt * number of colors on the shirts) = total cost of the order

75 * 2 + 50 * x = C

150 + 50x = C

C = 50x + 150

The number of colors on the shirts (x) can vary change; if the number of colors used increases, the cost of the order increases & if the number decreases, the cost of the order decreases

The printing company charges is fixed as every member is to get a shirt

Describe why the prime factorization of a number is sometimes written with exponents?
Katen [24]
Say you wanted to write the prime factorization of 8.
Its prime factorization <em>can</em> be written as 2 × 2 × 2, but it would be much easier to just write it as 2³ (2 times itself 3 times)
