Find measure of angle Y.

ludmilkaskok [199]

Sum of inside angles of a polygon= 180º(n-2)
n=number of sides.
This polygon has 6 sides, the sum of all its angles would be=180º(6-2)=720
let´s:
xº=inside angle
xº=720º-sum of the others inside angles.
xº=720º-(75º+130º+120º+105º+145º)=720º-575º=145º

yº=180º-xº=180º-145º=35º

Answer: yº=35º

The weekly cost (C) of growing and selling x acres of flowers is approximated by C = 0.2x2 – 12x + 240. How many acres of flower

Anna71 [15]

To determine how many acres would minimize cost, we need to differentiate the expression given and set it to zero and obtain the value of x. We do as follows:

C(x) = 0.2x^2 - 12x +240
C'(x) = 0.4x - 12
0 = 0.4x - 12
x = 30 acres <---------amount of flowers needed to minimize cost

____× 105 is 3,000 times greater than 2.3 × 102 and is _____ times greater than 1.38 × 101.

musickatia [10]

For this case we must calculate the values of the unknowns.
We have then:
$x * 10 ^ 5$ is 3,000 times greater than $2.3 * 10 ^ 2$
We have the following equation:
$(x * 10 ^ 5) / (2.3 * 10 ^ 2) = 3000
$
From here, we clear the value of x:
$x = (10 ^ 2/10 ^ 5) * (2.3 * 3000)

x = 6.9$
Then, on the other hand we have:
"and is _____ times greater than 1.38 × 101"
That is, we have the following equation:
$(6.9 * 10 ^ 5) / (1.38 * 10 ^ 1) = y
$
The value of y is:
$y = 50000
$
Answer:
6.9 × 105 is 3,000 times greater than 2.3 × 102 and is 50000 times greater than 1.38 × 101.
