The answer is 60.
The formula for finding the area of a trapezoid or trapezium (UK) is
Base1 and base2 can be either 8 or 12 and the height is 6.
Then Solve for parenthesis first.
Then multiply to get the answer.
Answer:
Answer:
A. x = 15
Step-by-step explanation:
2x + 3 * (x - 10) = 45
2x + 3x - 30 = 45
5x - 30 = 45
5x = 75
x = 15
Answer:
The answer is 4/9 if the problem is:
.
Step-by-step explanation:
I think this says:
.
Please correct me if I'm wrong about the problem.
Here are some useful limits we might use:
So for our limit... I'm going to multiply top and bottom by the conjugate of the bottom; that is I'm going to multiply top and bottom by :
When you multiply conjugates you only have to do first and last of FOIL:
By the Pythagorean Identities, the denominator is equal to :
I'm going to divide top and bottom by in hopes to use the useful limits I mentioned:
Let's tweak our useful limits I mentioned so it is more clear what I'm going to do in the following steps:
The bottom goes to 1. The limit will go to whatever the top equals if the top limit exists.
So let's look at the top in hopes it goes to a number:
We are going to multiple the first factor by the conjugate of the top; that is we are multiply top and bottom by :
Recall the thing I said about multiplying conjugates:
We are going to apply the Pythagorean Identities here:
Ok this looks good, we are going to apply the useful limits I mentioned along with substitution to find the remaining limits:
The limit is 4/9.
Answer:
The 135 external angle means its corresponding internal angle is (180–135) 45 degrees. The other internal angle of 65 plus the 45 is 110 degrees. Since the sum of degrees in the angles in a triangle is 180, the other interior angle is (180–110), or 70 degrees.
Step-by-step explanation:
Unit rate means how much does it cost for 1 item for example...if you can download 2 songs for $5 how much did it cost to download 1 song...you would simply take $5 divided by 2 to get $2.50
In this case we have 5 yards of fabric for $18 so all we have to do is take $18 divided by 5 to find out how much just 1 yard costs.
so $18 divided by 5 is $3.60 so the unit rate cost per yard is $3.60
to make sure this is correct you can check your answer like this. If it is $3.60 for 1 yard how much would it be for 5 yards? Multiply $3.60 and 5 if we get $18 then our answer is correct. $3.60 x 5 does equal $18 so we were correct
