Call KE as a, KI as b
To calculate the perimeter of a kite, we use the formula : 2(a+b)
The perimeter is 42cm, hence a + b = 42/2 = 21 cm
Now, we can write the ratio between a and b as 2:1 (because KE is twice as long)
So, we can calculate KI by taking the sum and divide by the total ratio parts
21 : (2 + 1 ) = 7
Recheck : KI = 7 -> KE = 14
Perimeter = (7+14) x 2 = 42, and 14 is indeed 2 x 7.
A washer and a dryer cost $669 combined. The washer costs $81 less than the dryer. What is the cost of the dryer?
Answer:
$375
Step-by-step explanation:
Given:
A washer and a dryer cost $669 combined. The washer costs $81 less than the dryer.To Find:
What is the cost of the dryer?
Solve:
Let's the price of the washer is w and the price of the dryer is d.
Thus,
w + d = 669
d - 81 = w
To find the cost of the dryer, we just need to substitute it for w in the first equation:
(d - 81) + d = 669
2d - 81 = 669
2d = 750
d = 375
Hence the cost of the dryer is $375.

Answer:
15. 80 benches
16. 45 cost units
Step-by-step explanation:
The two problems together are asking you to find the coordinates of the vertex of the cost function. To do this you can use the procedure for writing a quadratic in vertex form.
C(x) = 0.1x^2 -16x +685
= 0.1(x^2 -160x) +685 . . . . . . factor out the leading coefficient
= 0.1(x^2 -160x +6400) +685 -(0.1)(6400) . . . add and subtract 0.1(6400)
C(x) = 0.1(x -80)² +45 . . . cost function in vertex form
__
15.The number of benches that minimizes the cost function is the x-coordinate of the vertex. That is the value that makes the square equal to zero.
x = 80 . . . benches
__
16.The minimum value of the cost function is the value obtained when the squared term is zero:
C(80) = 0.1(80 -80)² +45
C(80) = 45
The minimum cost per bench is 45. (The problem statement gives no units for cost. It could be pesos, or millions of rubles. We can't tell.)

Additional comment
The square of a binomial is ...
(x +a)² = x² +2ax +a²
You will notice that the constant (a²) is the square of half the x-coefficient. To "complete the square", we put the equation in a form where we have (x² +2ax) in parentheses. Then we divide the x-coefficient by 2, and add its square inside parentheses: (x² +2ax +a²) and rewrite to the form of a square: (x +a)².
In order to keep the expression the same, we must subtract the same quantity elsewhere in the equation. Outside parentheses, it must be multiplied by the coefficient in front of the parentheses. In the above, we added (0.1)(6400) and subtracted (0.1)(6400) so that we could rearrange the cost function to vertex form: a(x -h)² +k has vertex (h, k).
__
We find a graphing calculator to be an extremely handy tool for dealing with polynomial functions. The attached shows the graph of the cost function. The calculator marks the vertex for us. Since it is a plot of cost versus number of benches, the units of the vertex are (benches, cost units).
There are 12 corn stalks, 6 tomato plants, 4

O 5/12
O 4/24
O 6/10

The probability of randomly picking a tomato or squash plant from the garden is 5/12.
What is probability ?Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
What is the probability of randomly picking a tomato or squash plant from the garden?Probability = (total number of tomato / total number of fruits) + (total number of squash / total number of fruits)
total number of fruits = 12 + 6 + 4 + 2 = 24
(6/24) + (4/24) = 10/24 = 5/12

For 0, this is a special case. It always stays as 0, because -0 does not exist.

Which data value is farthest from the mean? How far you is this value from the mean? Round to the nearest hundredths. 34,37,48,32,25,34,35,23,33,30.
Answer:
48; 14.90 or 14.9
Step-by-step explanation:
First you have to take the mean of the data set.
In order to do this, we take the sum of all of the data points and then divide them by the number of values like so...
[tex]\frac{34+37+48+32+25+34+35+23+33+30}{10}[/tex]
The answer to this is 33.1.
Now we have to find the value furthest from this value. In order to do this, we are going to take the highest (48) and the lowest value(23). Then we compare their distance from 33.1. After this, we can tell that 48 is further from 33.1 than 23 is.
Then for the second part, 48-33.1 = 14.90 and that is how far the value is from the mean.

the standard form of the equation
for this line?
Answer:
y = [tex]\frac{x}{4}[/tex] - 2
Step-by-step explanation:
y - 1 = 1/4 (x - 12)
y - 1 = 1/4 (x) -3
y = 1/4 (x) -3 +1
