So 60 by 80,
60 <80 so 60=width
she moves it so that width=300
findn height
60:300=80:x
60/300=80/x
muliplyb oth sides by x
60x/300=80
x/5=80
mulitpliy both sides by 5
x=400
the height=400 mm
Ac=4 bx=y+4 doesn't make sense. Perhaps you meant <span>Ac-4bx=y+4. If this is not correct, ensure that you have copied down the original problem correctly.
</span>To solve Ac-4bx=y+4 for y, subtract 4 from both sides of this equation. You'll get:
Ac-4bx-4 = y+4 - 4, or y = ac-4bx - 4.
Answer:
540 pages
Step-by-step explanation:
100 pages = 50 mins
??? pages = 270 mins (converted 4hrs 30 mins to minutes)
Now you could cross multiply to find what the number of pages are:
100 pages x 270 mins = 50 mins x ??? pages
27000 = 50 mins x ??? pages
27000/50 = ??? pages
540 = ??? pages
So there are 540 pages in his favourite book.
Answer: 111.72 m^2 if they want round its 112
Is from O to C 14m
A=pixr^2
3.14x14^2= 615.44 m/2 half circle = 307.72
Area of triangle A= 1/2bh. .5x28x14=196
307.72-98=196= 111.72 m^2
Step-by-step explanation:
To do this without a calculator, it may be easier to break the number into smaller parts.
420 * 6
= (400 * 6) + (20 * 6)
= 2400 + 120
= 2520
Hope this helps! :)
