Answer:
none of these are right but the answer is 2x - y = -1.
D would be right but there is a negative sign in front of 2x.
Step-by-step explanation:
The diagram of each shape are shown below
The shapes that have two consecutive angles of 90° is square and rectangle, so the correct option is option A
Answer:
d = 1/18
Step-by-step explanation:
V=LWH=20
L is 5 more than W
V=5+W
H is 1 less than W
H=-1+W
easy, sub 5+W for L and -1+W for H in LWH=V=20
20=(5+W)(W)(-1+W)
expand
20=W^3+4W^2-5W
minus 20 both sides
W^3+4W^2-5W-20=0
either factor or graph to find the possible values for W
(W+4)(W^2-5)=0
set each to zero
W+4=0
W=-4
impossible, measures cannot be negative
W^2-5=0
add 5
W^2=5
sqrt both sides
W=√5
sub back
L=5+W
L=5+√5
aprox
7.24 rounded
H=-1+W
H=-1+√5
aprox
1.24 rounded
the dimentions are
√5 by (5+√5) by (-1+√5) or aprox
2.24in by 7.24in by 1.24in
Answer:
The linear equation and Erin can pick apples per hour if she maintains a constant rate.
Step-by-step explanation:
To find the linear equation of the relationship from the graph.
We have to find the coordinates .
Let say and
Here variable is the time in hour and variable is the number of apples.
To find linear equation we have to find the slope (m) of the line by using point-slope form.
So,
The the linear equation will be.
Number of apples Eric pick in an hour is .
By plugging the value of in the equation we can find the number of apples picked by Erin per hours subsequently for second hour.
In each hour she picks apples.
Linear equation is and number of apples picked by Eric in an hour is .
