Answer:
The perimeter will be 10 times the original.
Step-by-step explanation:
Formula for Perimeter of rectangle is
2l + 2 w. From the diagram shown, the perimeter is 2×6 +2×3 = 12+6 =18cm
If if each side is increased by a factor of 10
Our length becomes 6×10= 60cm
Our width becomes 3×10= 30cm
New perimeter becomes
2×60 + 2×30
= 120+60 = 180cm
New perimeter(180 cm)= 10× original perimeter (18cm)
So The perimeter will be 10 times the original.
i think maybe ? x+20*2=5-2*x
Answer:
24
Step-by-step explanation:
Using Pythagoras theorem,
a^2 = b^2 + c^2
40^2 = 32^2 + c^2
1600 = 1024 + c^2
1600 - 1024 = c^2
576 = c^2
square root of 576 = c
24 = c
Each guest should get 144 cookies. This is because there are 432 cookies, and three guests. 432/3 = 144. :D Hope I helped!
Answer:
17. a)
Step-by-step explanation:
17.
f(x) =x/2, then f(x-3)=(x-3)/2
x=3, f(x-3)=f(3-3)=f(0)=0 (values in table)
f(x-3)+3=0+3=3
18.
f(x) =x/2
f(x-2) for x=5 is f(5-2)=f(3)=3/2
f(x-2)+5=f(3)+5=3/2+5=3/2+10/2=13/2
