Answer:
2.30/7.5
Step-by-step explanation:
4.30-2=2:30
2.5-10=7.5
Answer:
Well I figure you would use a ratio. we are given one when comparing 240 lbs to 180 calories for each mile:
240lbs/180calories = 1 mile
we.are.given another when saying a person. burns 36 calories in 1 mile. we don't know weight so we will say x lbs:
x/36calories = 1 mile
since they both equal 1 mile we know they are equal:
240/180 = 1 = x /36
we can get rid of the 1 in between and say:
240/180 = x/36
let's reduce first fraction
8/6 = x/36
cross multiply:
8*36 = 6x
divide both sides by 6
8*6 = x
x = 48

Step-by-step explanation:
Answer:
x= 32°
Step-by-step explanation:
the sum of all angles inside a triangle is 180°
to find x° = 180° - 98° - 50°
x= 32°
Answer:
SA = 3,600π cm²
Step-by-step explanation:
You are given the formula, and the diameter. The formula uses radius, which is 1/2 of the diameter. In this case, r = 30. Plug that into the formula and simplify...
SA = 4π(30²)
SA = 4π(900)
SA = 3,600π
