Answer:
82%
Step-by-step explanation:
Multiply 25*4 to get 100.
Then multiply 20.5*4 because what you do to one side you have to do for the other.
You end up with 0.82 or 82%
Based on the length of the field and the amount of the field that was planted the fraction of the field planted is 4.1/5.
The field has a length of 25 acres and Peter plants in 20.5 acres of them.
The fraction that is planted is:
= Amount of field planted on / Total area of field
Solving will give:
= 20.5 / 25
Take to the simplest form by dividing both by 5:
= 4.1 / 5
In conclusion, the fraction planted on is 4.1/ 5.

If x= -4 and y= -3 what does 3x - 2y equal
Answer:
-6
Step-by-step explanation:
3(-4) = -12
-2(-3)= 6
-12+6= -6
Answer:
-6
Step-by-step explanation:
If x = -4 and y = -3, the equation should be set up like this: 3(-4) - 2(-3). The rule is if you multiply a 1 positive number by 1 negative number, the answer will be negative.
3(-4) = -12
2(-3) = -6
Then, once you figure out the multiplication, finish up the equation by subtracting.
-12 - (-6) = -6

write an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4
Answer:
We conclude that an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4 will be:
[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]
Step-by-step explanation:
Given the line
y+2x=4
converting into the slope-intercept form y = mx+b where m is the slope
y = -2x+4
comparing with the slope-intercept form
Thus, the slope is: m = -2
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = -2
The slope of the new line perpendicular to the given line = – 1/m
= -1/-2 = 1/2
Using the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 1/2 and the point (-3, 5)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-5=\frac{1}{2}\left(x-\left(-3\right)\right)[/tex]
[tex]y-5=\frac{1}{2}\left(x+3\right)[/tex]
Add 5 to both sides
[tex]y-5+5=\frac{1}{2}\left(x+3\right)+5[/tex]
[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]
Therefore, we conclude that an equation in slope-intercept form for the line that passes through (-3,5) and is perpendicular to the graph of y+2x=4 will be:
[tex]\:y=\frac{1}{2}x+\frac{13}{2}[/tex]

The value y of an investment x months after the money was invested is given according to the equation below. y = 25,000(1.16)-x As time goes on, does the value of the investment grow or decay?
Answer:
Decay
Step-by-step explanation:
The value, y of an investment x is given by:
y = 25000(1.16)^-x
x = number of month after investment
y = value of investment after x months
The function f(y) above is an exponential usually related in the form:
y = Ar^-x
Plugging values of x into the function :
After 1 month; x = 1
y = 25000(1.16)^-1 = 21551.724
After 2 month; x = 2
y = 25000(1.16)^-2 = 18579.072
After 3 month; x = 3
y = 25000(1.16)^-3 = 16016.441
Since y is decreasing with increasing value of x, then we have a decay
Answer:
Decay

Two cylinders are shown below. Find the volume of each cylinder. Use 3.14 for pie. Enter your answers rounded to the nearest hundredth.
Given:
For cylinder P: radius = 4.25 in. and height = 14 in.
For cylinder Q: radius = 7 in. and height = 8.5 in.
To find:
The volume of each cylinder.
Solution:
Volume of a cylinder is
[tex]V=\pi r^2h[/tex]
where, r is radius and h is height. Use 3.14 for [tex]\pi[/tex].
Using the above formula, the volume of cylinder P is
[tex]V_P=(3.14)(4.25)^2(14)[/tex]
[tex]V_P=794.0275[/tex]
[tex]V_P\approx 794.03[/tex]
Using the above formula, the volume of cylinder Q is
[tex]V_Q=(3.14)(7)^2(8.5)[/tex]
[tex]V_Q=1307.81[/tex]
Therefore, the volume of cylinder P is 794.03 sq. in. and volume of cylinder Q is 1307 sq. in.
The volume of cylinder P is 794.03 sq. in. and the volume of cylinder Q is 1307 sq. in.
What is the volume of a right circular cylinder?Suppose that the radius of the considered right circular cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
The given information is
For cylinder P:
radius = 4.25 in. and height = 14 in.
For cylinder Q:
radius = 7 in. and height = 8.5 in.
To find the volume of each cylinder.
The volume of a cylinder
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
where r is radius and h is height.
Using the above formula,
the volume of cylinder P
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
[tex]V = 3.14 \times (4.25)^2 \times 14 \: \rm unit^3\\\\V = 794.03[/tex]
The volume of cylinder Q
[tex]V = \pi r^2 h \: \rm unit^3\\\\V = 3.14 \times 7^2 \times 8.5 \: \rm unit^3\\\\V =1307.81[/tex]
Therefore, the volume of cylinder P is 794.03 sq. in. and the volume of cylinder Q is 1307 sq. in.

If T is the circumcenter of triangle MNP, find each measure.
Answer:
8). TN = 22 units ; 9). √165
Step-by-step explanation:
The circumcenter of a triangle is the point in the plane equidistant from the three vertices of the triangle.
8). 6x - 56 = 3x - 17
3x = 39
x = 13
TN = 22 units
9). 4x - 17 = x + 10
3x = 27
x = 9
TN = 19
RT = [tex]\sqrt{TN^2 - RN^2}[/tex]
RT = [tex]\sqrt{361-196}[/tex] = √165 ≈ 12.8 units
Applying the properties of circumcenter of a triangle and the Pythagorean Theorem, the measure of each given segments are calculated as:
8. TN = 22
9. RT = 12.8
Recall:
The point where the three perpendicular bisectors of a triangle meet is known as the circumcenter of the triangle.The perpendicular bisectors form right angles with each side it bisects. This means that there are two opposite right angles formed at point Q, S, and R.The circumcenter is also the point that is equidistant to all three vertices of the triangle. This means that, in the diagram given, MT, TN, and TP are equal.Pythagorean theorem can be used to solve for the missing side of a right triangle. It states that, if c is the hypotenuse (longest side that is directly opposite to the right triangle), and a and b are the two other smaller sides, therefore: [tex]c^2 = a^2 + b^2[/tex]8. Find TN
Given,
MT = 6x - 56TP = 3x - 17Thus,
6x - 56 = 3x - 17 (MT = TN = TP, because they are equidistant from the circumcenter, T.)
Combine like terms6x - 3x = 56 - 17
3x = 39
Divide both sides by 3x = 13
TN = TP = 3x - 17
TN = 3x - 17
Plug in the value of xTN = 3(13) - 17
TN = 22
9. Find RT
Given,
RN = 14TN = 4x - 17TP = x + 10Thus,
4x - 17 = x + 10 (TN = TP)
Combine like terms4x - x = 17 + 10
3x = 27
Divide both sides by 3x = 9
TN = 4x - 17
Plug in the value of xTN = 4(9) - 17
TN = 19
To find RT, apply the Pythagorean Theorem
[tex]RT = \sqrt{TN^2 - RN^2}[/tex]
Substitute[tex]RT = \sqrt{19^2 - 14^2}\\\\\mathbf{RT = 12.8}[/tex]
In summary, applying the properties of circumcenter of a triangle and the Pythagorean Theorem, the measure of each given segments are calculated as:
8. TN = 22
9. RT = 12.8

Madelyn has already cycled 4 kilometers this year, plus she plans to cycle 2 kilometers during each trip to work. Write an equation that shows the relationship between the number of trips to work x and the total distance cycled y.
Answer: y = 4km + 2km*x
Step-by-step explanation:
We know that Madelyn already cycled 4km this year, so we start at that point.
Now, each time that she goes to work, she cycles 2 km in total.
Now, if she does x trips to work, then she cycles 2km x times, this means that in total she would cycle 2km*x
if we also count the 4km she already has, we have the linear equation:
y = 4km + 2km*x
This is the equation we wanted to get.
