He had 37 feet of wood and he needs 36.1 feet of perimeter for triangular garden , as 37 > 36.2, he has enough wood to make the border.
What is perimeter?The entire distance encircling a shape is referred to as its perimeter. It is the length of any two-dimensional geometric shape's outline or boundary. Depending on the dimensions, the perimeter of various figures can be the same size.
Consider a triangle made of an L-length wire as an example. If all the sides are the same length, then the same wire can be used to create a square. Take a look at the illustration below, which shows the bounds of a rectangular park.
David is planning to build a triangular garden with a border made out of wood.
Two of the sides will be length = 16.4 feet
= 2 × 16.4
= 32.8 feet
The other side will be 3.3 feet
The perimeter of the triangular garden
= 32.8 + 3.3
= 36.1
Thus, He had 37 feet of wood and he needs 36.1 feet of wood, as 37 > 36.2, he has enough wood to make the border.

A booth at the State Fair recorded the number of items sold in the chart below. What is the ratio of lemonade and sodas sold to the number of candy bars sold?
Answer:
7:6
Step-by-step explanation:
add the amount of lemonade and soda together, that is 42.
so you have 42:36.
you need to simplify it, so you divide 42 / 2 = 21
then you divide 36 / 2 = 18.
so now you have 21:18.
then you divide 21 / 3 = 7
then you divide 18 / 3 = 6.
so therefore, your answer is 7:6.

The reason for the statements for the algebraic proof is as follows;
Multiplication property of equalityDivision property of equalityHow to solve equation with reasons?The equation given is as follows:
3x / 6 = 4 . This equation is given.
Therefore,
3x / 6 = 4
Using multiplication property of equality, we will multiply both sides of the equation by 6.
3x / 6 × 6 = 4 × 6
3x = 24
The multiplication property of equality states that when we multiply both sides of an equation by the same number, the two sides remain equal.
Hence,
3x = 24
Using division property of equality, we divide both sides by 3.
3x / 3 = 24 / 3
x = 8
The Division Property of equality says that dividing both sides of an equation by the same number does not affect the equation.

The dosage of a cold medication is 2 mg for every 80 lb of body weight. How many milligrams of this medication are required for a person who weighs 140 lb? mg
Let x represent the amount of milligrams required for a person who weighs 140 lb.
We were told that the dosage of a cold medication is 2 mg for every 80 lb of body weight. The equations would be set up as shown below
2 = 80
x = 140
By crossmultiplying, we have
x * 80 = 2 * 140
80x = 280
We would divide both sides of th equation by 80. We have
80x/80 = 280/80
x = 3.5
Therefore, 3.5 milligrams of this medication are required for a person who weighs 140 lb

Find the values at the 25th and 60th percentiles for the data set. The value at the 25th percentile is_____.
Answer:
25th percentile: 5
60th percentile: 12
Explanation:
To find the percentile, we need to organize the data from lowest to greatest, so
1 3 4 4 5 6 6 7 8 8 9 12 14 15 17 17 19 20 20 20
Therefore, there are 20 values in the data set.
The position of the 25th percentile can be calculated as:
[tex]\frac{25(n)}{100}=\frac{25(20)}{100}=5[/tex]Then, the position of the 25th percentile is 5th. In this case, the number in this position is 5 so the 25th percentile is 5
In the same way, we can calculate the position for the 60th percentile as follows:
[tex]\frac{60(n)_{}}{100}=\frac{60(20)}{100}=12[/tex]Then, the position of the 60th percentile is the 12th. In this case, this value is 12, so the 60th percentile is 12.
So, the answers are:
25th percentile: 5
60th percentile: 12
What is the equation of the line that is parallel to the line y = x + 4 and passes through the point (6, 5)?y = x + 3y = x + 7y = 3x – 13y = 3x + 5
You have to find a line that is parallel to y=x+4 and passes through the point (6,5)
Parallel lines always have the same slope.
The slope of the line is the coefficient that multiplies the x term, in this case, there is no number multiplying "x" but that does not mean that the line has no slope, turns out that the line has a slope equal to "1" when the variables (letters in an equation) are "alone" the coefficient is 1
So for both lines, the slope is
[tex]m=1[/tex]Using the slope and the known point of the line, you can determine the equation of said line by using the "point-slope" form
[tex]y-y_1=m(x-x_1)[/tex]Where
(x₁,y₁) are the coordinates of a point of the line
m is the slope
Replace the coordinates of the point and the slope in the formula

By writing and solving a system of equations, we will see that the club sold 32 oranges and 68 bars.
What the solution means?Here the solution will be the number of oranges and protein bars sold.
Let's define:
x = number of oranges.
y = number of bars.
We know that they sell 100 items and win a total of $304, then we can write the system of equations:
x + y = 100
x*$1 + y*$4 = $304
Isolating x on the first equation we get:
x = 100 - y
Replacing that in the other equation we get:
(100 - y)*$1 + y*$4 = $304
$100 - y*$1 + y*$4 = $304
y*$3 = $304 - $100 = $204
y = $204/$3 = 68
y = 68
And the value of x is:
x = 100 - y = 100 - 68
x = 32
That is the solution, x = 32 and y = 68.

This shows a scale drawing of Javier's room. The scale of his room is 1 cm = 2 ft. 5 cm 6.5 cm How much carpet does Javier need to purchase to completely cover his floor? A 130 square feet B. 120 square feet C. 111 square feet
Answer:
A 130 ft²
Step-by-step explanation:
if I understand this right, then the scale is 1 cm on a drawing is 2 ft in reality.
the room in the drawing measures 5 cm × 6.5 cm.
the question about how much carpet is needed is the question about the area of the floor of the rectangle room.
first e need to get the real measurements :
5 cm = 5×1 cm = 5 × 2 ft = 10 ft
6.5 cm = 6 5×1 cm = 6.5×2 ft = 13 ft
so, the real room is 10 ft × 13 ft.
and the area is therefore 130 ft².
1 The midpoint of AB is M. If the coordinates of A are (2,-6) and the coordinates of Mare (5, -1), find the coordinates of B.
The midpoint of two points is given as
(x1 + x2)/2, (y1 + y2)/2
Given that the coordinates of the midpoint are (5, -1), let the coordinates of point B be x2 and y2
(2 + x2)/2 = 5
2 + x2 = 10
x2 = 10 - 2
x2 = 8
(-6 + y2)/2 = -1
-6 + y2 = -2
y2 = -2 + 6
y2 = 4

[tex]\begin{gathered} T_n=5n+4 \\ T_9=49 \end{gathered}[/tex]Explanation:The given sequence is:
