The slope of the given line = 1 so the slope of the line perpendicular to it will be -(1/1) = -1.
It also passes through point (1, -1) so we use the point slope equation
y - y1 = m(x - x1)
y - -1) = -1(x - 1)
y + 1 = -x + 1
y = - x <--------- that's the answer
Answer:
$600.29.
Step-by-step explanation:
At the end of each month the value is multiplied by 107% = 1.07.
So after 6 months the value is 400(1.07)^6
= $600.29.
Answer:
1. 2×3.14×80
=502.4 m
4. 90 pound on Earth weighs 34 pounds on Mars.
If it weighs 135 pounds on earth, it will weigh x pounds on Mars
=90×=135×34
=90x=4590
=x=4590÷90
x=51 pounds
So therefore it weighs 51 pounds on Mars.
Step-by-step explanation:
in question 4 you have to cross multiply
Divide 138.16 by 3.14. This gives a diameter of 44 meters.
Hope this helped :)
There are 24 hours in a day.
Sleeping 8 out of those 24 hours means a fraction of 8/24.
8/24 = 4/12 = 2/6 = 1/3
So sleeping 8 hours a day means sleeping for 1/3 of the day.
