Answer:
562.5ml
Step-by-step explanation:
using percentage multipliers you just have to do:
add 0.25 to 1 because that will make 125%
then multiply it by 450ml
450ml x 1.25 = 562.5ml
Answer:
70 ft
Step-by-step explanation:
You want the actual width of a gym that is represented as 7 inches on a drawing with a scale of 1 in : 10 ft.
<h3>Scale factor</h3>
Each inch represents 10 feet, so 7 inches will represent ...
7 × 10 ft = 70 ft
The gym is 70 ft wide.
__
<em>Additional comment</em>
You can also write and solve an equation that shows the measures are proportional:
actual width / drawing width = (10 ft) / (1 in) = (gym width) / (7 in)
Multiplying both sides of this proportion by 7 in, we have ...
gym width = (7 in) × (10 ft)/(1 in) = 7 × 10 ft = 70 ft
For the first equation just solve for y
then plug into the 2nd one
then solve for x
The answer to this is 0.75
