Answer:
increase by 18
Step-by-step explanation:
put any number at c
f=32+1.8(5)
f=41
Then increase your number c by 10
f=32+1.8(15)
f=59
then figure out the difference
59-41=18
Perimeter of a rectangle:
P = 2(l + w)
Plug in what we know:
P = 2(16 + 7)
Add:
P = 2(23)
Multiply:
P = 46
Now find the perimeter of the semi-circle.
Perimeter of a circle:
P = pi * d
Plug in what we know:
P = 3.14 * 16
Multiply:
P = 50.24
Divide by 2 since it's a semi-circle:
50.24 / 2 = 25.12
Add the two perimeters:
46 + 25.12 = 71.12
Answer:
1 1/2
Step-by-step explanation:
12 divided by eight is 1.5, and 1.5 as a fraction is 1 1/2.
Point-slope form of a line: we need a point (x₀,y₀) and the slope "m".
y-y₀=m(x-x₀)
slope intercept form :
y=m+b
m=slope
If the line is parallel to y=2/3 x-0, the line will have the same slope, therefore the slope will be: 2/3.
Data:
(8,4)
m=2/3
y-y₀=m(x-x₀)
y-4=2/3(x-8)
y-4=2/3 x-16/3
y=2/3 x-16/3+4
y=2/3 x-4/3 (slope intercept form)
Answer: The equation of the line would be: y=2/3 x-4/3.
if we have the next slope "m",then the perendicular slope will be:
m´=-1/m
We have this equation: y=2/3 x+0; the slope is: m=2/3.
The perpendicular slope will be: m`=-1/(2/3)=-3/2
And the equation of the perpendicular line to : y=2/3 x+0, given the point (8,4) will be:
y-y₀=m(x-x₀)
y-4=-3/2 (x-8)
y-4=-3/2 x+12
y=-3/2x + 12+4
y=-3/2x+16
answer: the perpendicular line to y=2/3 x+0 , given the point (8,4) will be:
y=-3/2 x+16
Answer:
Normal speed = 711.11 km/h (Approx)
Step-by-step explanation:
Assume;
Normal speed = x
New speed = x - 25% of x = 0.75 x
Time taken = t
New time taken = t + 1.5 hour
Total distance
Computation:
Total distance = 3,200 km
Speed = Distance/Time
x = 3200 / t
t = 3200/x
so,
0.75 x = 3200 / (t+1.5)
0.75 x = 3200 / (3200/x+1.5)
0.75 x = 3200 / [(3200 + 1,5x)x]
x = 711.11 km/h
Normal speed = 711.11 km/h (Approx)
