DO Now Darryl lives on the third floor of his
apartment building. His bike is
locked up outside on the ground
floor. At 3:00 p. m., he leaves to go
run errands, but as he is walking
down the stairs, he realizes he forgot
his wallet. He goes back up the
stairs to get it and then leaves again.
As he tries to unlock his bike, he
realizes that he forgot his keys. One
last time, he goes back up the stairs
to get his keys. He then unlocks his
bike, and he is on his way at 3:10 pm
Sketch a graph that depicts Darryl's
change in elevation over time.

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10

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.

2x=70  

x=70/2

x=35

thats the answer

step-by-step explanation:

you need to know that the corresponding sides and angles are the same.
