Miguel recently sold some farmland and bought a new plot that consists of 968 acres. Miguel calculates that this is 20% less acreage than he used to own. What was the acreage of the old land?

Answers

Answer 1

Answer:

1210 acres

Step-by-step explanation:

Given data

let the old farmland be x acres

new farmland = 968 acres

therefore

let us find 20% of the old farmland

=20/100x

=0.2x

Hence

968+0.2x=x

collect like terms

968=x-0.2x

968=0.8x

x= 968/0.8

x=1210 acres

since there are no numbers, i will assume that the length of recess is 1 minute, or x. if social studies is 4 more than 2 times the length of recess, we can use the equation x*2+4 to solve the problem. the end result will be 6 minutes. Social studies is 6 minutes longer than recess

Answers

Answer:

79

Step-by-step explanation:

Given the expression

x + 1/x = 9

Square both sides

(x + 1/x)^2 = 9^2

x^2 + 2x(1/x)+ (1/x)^2 = 81

x^2 + 2 + 1/x^2 = 81

x^2+1/x^2+2 = 81

x^2+1/x^2 = 81-2

x^2+1/x^2+ = 79

Hence the value of x^2+1/x^2 is 79

Yes no solution show work

Answers

Answer:

see explanation

Step-by-step explanation:

Given

3(x - 6) = - 15 + 3x ← distribute parenthesis on left side

3x - 18 = - 15 + 3x ( add 18 to both sides )

3x = 3 + 3x ( subtract 3x from both sides )

0 = 3 ← not possible

This indicates the equation has no solution

A rectangular billboard is 9.35 meters wide and 6.82 meters tall. What is the perimeter of the billboard in meters?

Answers

Answer:

32.34 meters

Step-by-step explanation:

All you need to do is label the rectangle with the information given. 9.35 for width, and 6.82 for length.

Next, just fill in the other sides and add. Because it's a rectangle, then you should be able tp label the blank sides.

Next, just add all the sides together and then you'll get your perimeter!                                                    

                                9.35 + 9.35+ 6.82 + 6.82= 32.34

During the 2005 football season team tackle the team sack by eight points if the combine scores total of 26 find the individual team scores

Answers

Answer:

Team sack = 9

Team tackle = 17

Step-by-step explanation:

To start with, we'd assume that

Let x = the points scored by Team Sack

Let x + 8 = the points scored by Team Tackle

x + x + 8 = 26

So, go further and solve mathematically

2x + 8 = 26

if we subtract 8 from both sides, we have

2x = 18

Next, we then divide both sides by 2. So that,

x = 18/2

x = 9

Since we assumed the total points for Team Sack to be x, then Team Sack scored 9 points while Team Tackle scored x + 8 points, and that is 17

A triangle has vertices at (1,10), (-5,2), and (7,2). What is its orthocenter. Show your work.

Answers

Answer:

Question: What is the orthocenter of a triangle with the vertices (-1,2) (5,2) and (2,1)?

The coordinates of point A are (-1,2), point B are (5,2), and point C are (2,1).

The orthocent is the intersection of the three altitudes. An altitude goes from a vertex and is perpendicular to the line containing the opposite side.

In the coordinate plane the equations of the altitudes can be found and then a system of equations can be solved.

Altitude 1. From point C perpendicular to the line containing side AB.

Slope of line AB is 0 (horizontal line), a vertical line is perpendicular to a horizontal line. Thus, the equation of altitude 1 is  x=2 .

Altitude 2. From point B perpendicular to the line containing side AC.

Slope of line AC is  −13 , the slope of a line perpendicular to line AC is 3. The equation of altitude 2 is  y=3x−13  

Altitude 3. From point A perpendicular to the line containing side BC.

Slope of line BC is  13 , the slope of a line perpendicular to line BC is  −3 . The equation of altitude 3 is  y=−3x−1  

The orthocenter is the point where all three altitudes intersect.

x=2  

y=3x−13  

y=−3x−1  

Use substitution to solve the first two equations  y=3(2)−13=−7  

The orthocenter is the point  (2,−7)  

we did not need the third equation, but we can use it as a check, plug the coordinates into the third equation:

−7=−3(2)−1  

−7=−6−1  

−7=−7  it works.
