Answer:
35 slices originally
Step-by-step explanation:
1. 0.4 means 40%
2. if 14 slives equal 40% we need to divide by 4 to find 10%
3. 14 divided by 4 is 3.5
4. then we multiply 3.5 (10% of the cake) by 10 because 10•10=100(%)
3.5•10 equals 35 slices
Answer:
y = 2x
Step-by-step explanation:
calculate the slope of AB using the slope formula
m =
with (x₁, y₁ ) = A (8, 3) and (x₂, y₂ ) = B (12, 1 )
= = = -
given a line with slope m then the slope of a line perpendicular to it is
= - = - = 2
the equation of a line passing through the origin (0, 0 ) is
y = mx
here m = 2 , then
y = 2x ← equation of perpendicular line
X+(x+1)+(x+2)+(x+3)+(x+4)+(x+5)=393
6x+15=393
6x=393-15
6x=378
x=63
third one is 63+2=65
2πr is the perimeter or circumference of a circle
.
diameter is 32cm so radius=16cm
2*3.14*16=100.48cm is long
