Abes apples orchard plants both green apple trees and red apple trees this planting will include 21 red apple trees and 18 green apple trees what is the ratio of green apple trees and red apple trees
Answer:
The ratio of green apples to red apples is .
Step-by-step explanation:
Given,
Number of red apples = 21
Number of green apples = 18
We have to find out the ratio of green apples to red apples.
Solution,
For finding the ratio we have to divide the number of green apples to the number of red apples.
So, we can frame the above sentence as;
Ratio = number of green apples/number of red apples
Now substituting the values, we get;
Ratio= 18/21 = 6/7
Hence The ratio of green apples to red apples is . 6/7

In ARST, r = 1.7 inches, s = 7.3 inches and ZT=15°. Find the length of t, to the nearest
10th of an inch.
Answer:
The answer is "5.7"
Step-by-step explanation:
Using the cosine rule.
[tex]\cos T = \frac{r^2+s^2-t^2}{2rs} \\\\t^2= r^2+s^2-2rs \cos T ........(i)\\\\r=1.7\\s=7.3\\T=15\\\\t^2= (1.7)^2+(7.3)^2-2(1.7)(7.3) \cos 15^{\circ} \\\\[/tex]

A piece of paper is to display ~128~ 128 space, 128, space square inches of text. If there are to be one-inch margins on both sides and two-inch margins at the bottom and top, what are the dimensions of the smallest piece of paper (by area) that can be used? Choose 1 answer:
Answer:
The dimensions of the smallest piece that can be used are: 10 by 20 and the area is 200 square inches
Step-by-step explanation:
We have that:
[tex]Area = 128[/tex]
Let the dimension of the paper be x and y;
Such that:
[tex]Length = x[/tex]
[tex]Width = y[/tex]
So:
[tex]Area = x * y[/tex]
Substitute 128 for Area
[tex]128 = x * y[/tex]
Make x the subject
[tex]x = \frac{128}{y}[/tex]
When 1 inch margin is at top and bottom
The length becomes:
[tex]Length = x + 1 + 1[/tex]
[tex]Length = x + 2[/tex]
When 2 inch margin is at both sides
The width becomes:
[tex]Width = y + 2 + 2[/tex]
[tex]Width = y + 4[/tex]
The New Area (A) is then calculated as:
[tex]A = (x + 2) * (y + 4)[/tex]
Substitute [tex]\frac{128}{y}[/tex] for x
[tex]A = (\frac{128}{y} + 2) * (y + 4)[/tex]
Open Brackets
[tex]A = 128 + \frac{512}{y} + 2y + 8[/tex]
Collect Like Terms
[tex]A = \frac{512}{y} + 2y + 8+128[/tex]
[tex]A = \frac{512}{y} + 2y + 136[/tex]
[tex]A= 512y^{-1} + 2y + 136[/tex]
To calculate the smallest possible value of y, we have to apply calculus.
Different A with respect to y
[tex]A' = -512y^{-2} + 2[/tex]
Set
[tex]A' = 0[/tex]
This gives:
[tex]0 = -512y^{-2} + 2[/tex]
Collect Like Terms
[tex]512y^{-2} = 2[/tex]
Multiply through by [tex]y^2[/tex]
[tex]y^2 * 512y^{-2} = 2 * y^2[/tex]
[tex]512 = 2y^2[/tex]
Divide through by 2
[tex]256=y^2[/tex]
Take square roots of both sides
[tex]\sqrt{256=y^2[/tex]
[tex]16=y[/tex]
[tex]y = 16[/tex]
Recall that:
[tex]x = \frac{128}{y}[/tex]
[tex]x = \frac{128}{16}[/tex]
[tex]x = 8[/tex]
Recall that the new dimensions are:
[tex]Length = x + 2[/tex]
[tex]Width = y + 4[/tex]
So:
[tex]Length = 8 + 2[/tex]
[tex]Length = 10[/tex]
[tex]Width = 16 + 4[/tex]
[tex]Width = 20[/tex]
To double-check;
Differentiate A'
[tex]A' = -512y^{-2} + 2[/tex]
[tex]A" = -2 * -512y^{-3}[/tex]
[tex]A" = 1024y^{-3}[/tex]
[tex]A" = \frac{1024}{y^3}[/tex]
The above value is:
[tex]A" = \frac{1024}{y^3} > 0[/tex]
This means that the calculated values are at minimum.
Hence, the dimensions of the smallest piece that can be used are: 10 by 20 and the area is 200 square inches

What’s the measure of angle X?
Answer:
x = 84°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
129° is an exterior angle of the triangle, thus
x + 45° = 129° ( subtract 45° from both sides )
x = 84°
The 2 triangles formed by the tree/ shadow and Jordan/ shadow are similar and ratio of corresponding sides are equal, that is
let h be the height of the tree, then

h = 35
The height of the tree is 35 ft

[tex]\frac{3x}{5}-x=\frac{x}{15}-\frac{28}{3}[/tex] but what does x equal?
[tex]\frac{3\cdot20}{5}-20[/tex] = [tex]-8[/tex]
[tex]\frac{20}{15}-\frac{28}{3}[/tex] = [tex]-8[/tex]
Since both are equal to -8, that means [tex]\frac{3\cdot20}{5}-20[/tex] = [tex]\frac{20}{15}-\frac{28}{3}[/tex].
Which means that...
x = 20
