The width of the mural is 8ft... how'd I get that??? First , you need to know the formula for the area of a rectangle ... A = LxW. The length is 9 , so what number multiplied by 9 equals 72? 8! 9x8=72 . The perimeter equals 35 feet . How'd I get that??? The width and length should both be multiplied by 2 . 9x2=18 and 8x2=16 . 18+16=35 feet !

Lelu [443]

Answer:

Therefore the number of brown shells in each necklace was  = 2 brown shells.

Step-by-step explanation:

If Julie made identical necklaces then we can say that number of each different colored shells were equally distributed among the necklaces.

So we can say that to find the number of necklaces we have to find the GCD (greatest common denominator) of the different colored shells.

Therefore the GCD of 10, 15 and 20 is 5.

Therefore Julia made 5 necklaces.

Therefore the number of brown shells in each necklace was = \frac{10}{5} = 2 shells.

Volgvan

Answer:

Function B has the greater initial value because the initial value for function A is 4 and the initial value for Function B is 5

Step-by-step explanation:

  • <em>The initial value of a function is the output value of the function when the input value is 0</em>

Initial value of A is y=4 at x=0,

and

initial value of B is y=0*6+5= 5 at x=0

Function B has the greater initial value because the initial value for function A is 4 and the initial value for Function B is 5

The cost of a lack has increased by 30% to £65. Work out the original price
Sveta_85 [38]
Cost of lack increased by 30%

new cost of lack will be = 100% + 30% = 130%

We are given that new cost = £65

Thus 130% of original cost = 65

100% of original cost = 65 × 100/130 = £50

Thus original price was £50
