The formula S= 30fd can be used to estimate the speed, s, in miles hour that a car is traveling when it goes into a skid, where f is the coefficient of

friction and d is the length of the skid marks in feet.

per

On a busy highway with a speed limit of 70 mi/h, a truck ahead of Verna jackknifes

across the road. Verna skids to a stop 10 ft short of the truck. Her skid marks

measure 260 ft. Was Verna speeding?

No; her speed was only 63 mi/h.

Yes: her speed was 73.9 mi/h.

Yes: her speed was 75.3 mi/h

No: her speed was 70 mi/h

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
