Answer:
36 sq inches
Step-by-step explanation:
bases are the two parallel sides -- 8" and 4"
height is perpendicular to the base -- 6"
formula for area of a trapezoid: A = 1/2h·(sum of bases)
A = 1/2(6)(8 + 4)
A = 3(12)
A = 36 sq inches
Which expression is equivalent to \left(3^{-6}\times 3^{3}\right)^{-1}\normalsize?(3 −6 ×3 3 ) −1 ? 3^{-19}3 −19 3^{18}3 18 3^{-3}3 −3 3^{3}3 3
Answer:
27
Step-by-step explanation:
Given the expression
[tex]\left(3^{-6}\times 3^{3}\right)^{-1}\\[/tex]
According to law of indices, this can be written as;
[tex]\left(3^{-6+3})^{-1}\\\\= (3^{-3})^{-1}\\\\= 3^{-3*-1}\\\\= 3^3\\\\= 27[/tex]
Hence the required answer is 27
a box contains 18 blue flashlights 3 red flashlights 7 silver flashlights ans 2 black flashlights. the flashlights are identical in size and shape. if one flashlight is chosen at random what is the probability that the flashlight will be either blue or black?
Answer:
The answer is 20/30 or in simplified form 2/3
Step-by-step explanation:
The way I do it is I take the probability of blue flashlights, 18/30, added to the probability of black flashlights, 2/30. Then, you simplify by dividing both numbers by 10.

Neighbor B plans to construct a circular chain link fence around his pool. And, Neighbor C is putting a vinyl fence around three side of his front yard. Note: Diagrams are not drawn to scale. Intended fences are marked with a dashed line.
Answer:
- The neighbor that has the most amount of fence to put up is: Neighbor A.
- The neighbor that has the least amount of fence to put up is: Neighbor C.

To calculate the amount of fence that Neighbor A has to put up, you need to add the following distances:
Convert yards to feet (Remember that :
To calculate the amount of fence that Neighbor B has to put up, you need to use the formula for calculate the circumference of a circle:
Where r is the radius.
In this case, the radius is:

A bacteria culture initially contains 2000 bacteria and doubles every half hour.
-Find the size of the bacterial population after 100 minutes.
-Find the size of the bacterial population after 10 hours.
Answer:
the size of the bacterial population after 100 minutes is 20,158.7 bacteria
the size of the bacterial population after 10 hours is 2097152000 bacteria
Step-by-step explanation:
Given that
The bacteria contains 2000
It would be double at every half hour
We need to find out the size of the bacteria after 100 minutes & 10 hours
So,
The size of the bacteria after 100 minutes is
= 2000 × 2^(100 ÷ 30)
= 2000 × 10.079
= 20,158.7 bacteria
Now the size of the bacteria after 10 hours is
10 hours = 10 × 60 minutes = 600 minutes
= 2000 × 2^(600 ÷ 30)
= 2097152000 bacteria

Because it is in quadrant 3, cosine is negative. Hypotenuse=25, Adj=-24, Opp, -7. Cos=Adj/Hyp. -24/25
It is Given that tan θ = 7/24, and θ terminates in Quadrant III, Thus the value of cos θ is -24/25.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
Given tan θ = 7/24, and θ terminates in Quadrant III,
we want to determine the value of cos θ.
Because it is in quadrant 3, cosine is negative.
Hypotenuse = 25, Adjcent = -24, Opposite = -7.
Cos θ = Adjcent /Hypotenuse .

52 divided by 6 as a fraction
Answer:
52/6 = 8 and 2/3
Step-by-step explanation:
52 divided by 6 is 8 and 2/3
6 multiplied by 8 is 48
52-48 is 4
so 52/6 is 8 remainder 4
or you can divide 4 by 6
4/6 = 2/3
so it can also be 8 and 2/3
52 divided by 6 as a fraction in its simplest form is 8 2/3.
To express 52 divided by 6 as a fraction, you simply write it as:
52 / 6
To simplify the fraction, find the greatest common divisor (GCD) of the numerator (52) and the denominator (6), and then divide both the numerator and denominator by the GCD.
The GCD of 52 and 6 is 2.
Divide both the numerator and denominator by 2:
(52 / 2) / (6 / 2)
This simplifies to:
26 / 3
now, we have,
Divide 26 by 3:
26 ÷ 3 = 8 with a remainder of 2
The whole number part is 8, and the remainder (2) becomes the new numerator.
The denominator remains the same.
So, 26/3 as a simplified mixed number is: 8 2/3
So, 52 divided by 6 as a fraction in its simplest form is 8 2/3.

If JM = x + 17 and MK = 5x - 23 find JL
Answer: 54
Step-by-step explanation:
A parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. The length of JL is 54 units.
What is a rectangle?That parallelogram in which adjacent sides are perpendicular to each other is called a rectangle.
A rectangle is always a parallelogram and a quadrilateral but the reverse statement may or may not be true.
For a rectangle the length of the diagonals is equal, also the diagonals bisect each other in equal parts, therefore, we can say,
HM = JM = MK = ML
Substitute the value of JM and ML,
JM = MK
x + 17 = 5x - 23
x - 5x = -23 - 17
-4x = -40
x = 10
The length of JM can be written as,
JM = x + 17 = 10 + 17 = 27
Since HM = JM = MK = ML, therefore,
JL = (JM + ML) = 27+27 = 54 units
Hence, the length of JL is 54 units.
