Answer:
7500 km
Step-by-step explanation:
BC= √3250²-3000²= 1250 km
Complete travel= 3250 km+1250 km+3000 km= 7500 km
Answer: 7 years
Step-by-step explanation:
let x be the age of Mary
so John's age will be 2x
the equation becomes
2x+x=21
3x=21
x=21/3
x=7
Set the equation up as a proportion, where x = the height of the tree in feet
27/x = 4.5/5
cross multiply
(4.5)(x) = (27)(5)
(4.5)(x) = 135
divide the entire equation by 4.5 to isolate x
135/4.5 = 30
x = 30
the tree is 30 ft tall
-7y-4x=17y-2x=53
-4x=24y-2x=53
-2x=24y=53
24y+2x=53
You would have to solve one at a time.
y=53/24
y=2.21
x=53/2
x=26.5
We are given that s represents the annual sales in millions for a particular electronic item
In the year 2005, s was equal to 54,845.8
This means that, in the year 2005, the sales for this electronic device was 54,845.8 million
This also means that the company sold 54,845.8 million pieces of that device in the year 2005
Hope this helps :)
