Answer:
It didn't saying anything about rounding but the the dimensions in there exact form are:
and
.
Now if they said to round to the nearest hundredths the dimensions in this rounded form would be:
L=5.39 cm and W=5.19 cm
(Check your question again and see if you meant what you have)
Step-by-step explanation:
L is 5 less than twice W
L = 2W-5
Area of rectangle=L*W
Area is 28 means L*W=28.
I'm going to insert L=2W-5 into L*W=28 giving me
(2W-5)*W=28
Distribute
2W^2-5W=28
Subtract 28 on both sides
2W^2-5W-28=0
a=2
b=-5
c=-28
We are going to use the quadratic formula.
Plug in...
W needs to be positive so
And
Does L*W=28?
Let's check.
In the last step, I was able to do a quick multiplication because I was multiplying conjugates. (a+b)(a-b)=a^2-b^2.
Answer:
30°
Step-by-step explanation:
First we take the full amount of degrees from points A to C, which is given as 125° then subtract 94°, which is the given amount from points A to D, this results in 30°
You must get your answer and when you get your answer, you factor them.
Try this:
Jonny has 50 apples. He has 5 bags. How many apple does Jonny puts in each abg?
Answer:
dy/dt = -5/9 ft/s
Step-by-step explanation:
The track can be expressed as a circle or radius 45ft as follows:
Implicit derivate for getting dy/dt
Then:
Solving using the conditions. when x= 27 and y= 36 ; dx/dt=20 we have:
