Answer:
3.6 cm
Step-by-step explanation:
Note that:
Area = 1/2 x perimeter x apothem.
To find the Apothem, the formula =
Area ÷ (1/2 × Perimeter)
Area = 100.8cm²
Perimeter = 56 cm
Hence,
Apothem =
100.8 cm² ÷ (1/2 × 56 cm)
= 100.8cm² ÷ 28cm
= 3.6 cm
Therefore, the Length of the apothem is 3.6 cm
Find the length of BC please

Describe the steps you can use to graph the function y=2x^2-8
Answer:
The first thing you need to find is the axis of symmetry by using
-b/2a
after you find that, use it to find the vertex of
x
2
+
8
In this case x should equal
0
so
y
=
0
2
+
8
giving just 8
the y-intercept is 8 as
c
=
8
the graph should look like this
graph{x^2+8 [-11.5, 8.5, 0.84, 10.84]}
it is a parabola.

Step-by-step explanation:
A game has 50 cards with 10 each numbered 1 to 5,and a player must draw a 2 or a 3 to move out of the "start" position.
Answer:
The question isn't complete, so I will assume that we want to find the probability of moving out of the start position.
First, we know that there is a total of 50 cards.
of these 50 cards, we have:
10 with the number 1
10 with the number 2
10 with the number 3
10 with the number 4
10 with the number 5
To move out of the starting position, we need to draw a 2 or a 3.
And we have 10 of each, then there are 20 cards that allow us to move out of the start position.
The probability of moving out of the starting position in the first draw, is equal to the quotient between the number of cards that allow us to move out of the starting position (20) and the total number of cards (50), this is:
P = 20/50 = 2/5 = 0.4

A box contains 20balls,x of which are white.if the probability of selecting a non white ball at random is 3/5.find the value of x
Answer:
8
Step-by-step explanation:
So there are 20 balls.
3/5 of them are NOT white.
This means 2/5 of them ARE white.
So knowing this, lets find the number of white balls(x).
To do this, lets multiply the 20 total balls by the 2/5 of them that are white:
20/1*2/5
=
40/5
=
8
So we know that 8 of the balls are white!
Hope this helps! :)

Solve for x. The figure is a parallelogram
Answer:
x = 1
Step-by-step explanation:
The opposite angles in a parallelogram are congruent, then
94x + 1 = 95 ( subtract 1 from both sides )
94x = 94 ( divide both sides by 94 )
x = 1

Answer:

There are 0 solutions because the lines will never intersect (which is due to their slopes being the same).
Step-by-step explanation:
Because we don't have any numbers we're supposed to esitmate, but the important thing to realize is that the slopes are identical
so let's say our equations are
x+1
x-5
2.)
There are 0 solutions because the lines will never intersect (because their slopes are the same)
Answer:
see explanation
Step-by-step explanation:
The solution to a system of equations given graphically is at the point of intersection of the 2 lines.
Therefore if the lines are parallel, they never intersect and hence there is no solution.
The lines given appear to be parallel and so there is no solution.

Find KL pls fast correct answer
Answer:
14Step-by-step explanation:
According to intersecting secants theorem:
KL*JL = ML²Substitute values and solve for x:
(x - 1)(x - 1 + 7) = 12²(x - 1)(x + 6) = 144x² - 5x - 6 = 144x² - 5x - 150 = 0x² - 15x + 10x - 150 = 0x(x - 15) + 10(x - 15) = 0(x - 15)(x + 10) = 0x = 15x = -10 (ignored as negative)Find the value of Kl
KL = x - 1 = 15 - 1 = 14A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 70% pure antifreeze. The company wants to obtain 140 gallons of a mixture that contains 20% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed
Answer:
40 gallons of premium antifreeze and 100 gallons of water should be used to obtain 140 gallons of a mixture that contains 20% pure antifreeze.
Step-by-step explanation:
Since a chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture, and the premium antifreeze solution contains 70% pure antifreeze, and the company wants to obtain 140 gallons of a mixture that contains 20% pure antifreeze, to To determine how many gallons of water and how many gallons of the premium antifreeze solution must be mixed, the following calculation must be performed:
50 x 0.7 + 50 x 0 = 35
40 x 0.7 + 60 x 0 = 28
30 x 0.7 + 70 x 0 = 21
29 x 0.7 + 71 x 0 = 20.3
28.57 x 0.7 + 71.43 x 0 = 20
140 x 0.2857 = 40
Therefore, 40 gallons of premium antifreeze and 100 gallons of water should be used to obtain 140 gallons of a mixture that contains 20% pure antifreeze.
