180- (57.9+39.3) = 82.8 is the answer
Answer:
The correct factored form is (x -2)(x - 5)
Step-by-step explanation:
When looking for the numbers to go in the parenthesis, find numbers that multiply to the final term and add up to the middle term. To find these, list out the factors of 10.
1 * 10
-1 * -10
2 * 5
-2 * -5
As you can see, -2 and -5 add up to -7. So we select these to go in the parenthesis with x.
(x - 2)(x - 5)
We have been given that a bucket holds 121.4 ounces (oz) of water when full.
Further, we know that the bucket loses 0.04 oz of water per second.
We need to find the time when bucket will be 60% of its full volume.
Let us first find 60% of its full volume:
If we assume that bucket will be 60% of its full volume after x seconds, we can set up an equation:
Therefore, it will take the bucket 1214 seconds to get to 60% of full.
In the answer to a right triangle the hypotenuse is 15 cm and one of the legs measures 12 cm.Qual is the perimeter of this rectangle?
edge a = 12 units
Edge b = 9 units
edge c = 15 units
The angle = 53.1 degrees
angle B = 36.9 degrees
area = 54 square units
Now we have to
Determining the length of the triangle base.
Calculate the triangle height.
Multiplying the length of the base by the length of time.
Multiply by two

So first we distribute
1/3(9a-18)
a three can be factored out of (9a-18)=3(3a-6)
so 1/3 times 3(3a-6)=3a-6
so the equation end up as 6-a=3a-6
add 6 to both sides
12-a=3a
add a to both sides
12=4a
divide both sides by 4
3=a
so there is one solution or A
