Answer:
In about 2073, 3440 acres
Step-by-step explanation:
Determine the equation for each forest. Forest A: y=-105x+4000 Forest B: y=-30x+3600There are a number of ways to solve a system of equations, but for this we are first going to solve for x when -105x+4000=-30x+3600. In this case, x=5 1/3.Then, we are going to plug 5 1/3 in as x into one of our equations. To double check you have this right, you may do both. If our equation is y=-30(5 1/3)+3600, then y=3440.Add 5 1/3 decades or about 53 years to 2020.Therefore, they expect the area of the forests to be the same in about 2073. At this time, both will have an area of about 3440 acres.
In 2073 the areas of the forests to be the same.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Forest A had an area of about 4000 acres and Forest B had an area of about 3600 acres.
If Forest A to decrease at a rate of 105 acres per decade and the area of Forest B to decrease at a rate of 30 acres per decade.
let the number of decades occur be x
So, the equation is
4000 - 105x= 3600 - 30x
400 = 75 x
x= 5.33
x= 53.3 years
Hence, In 2073 the areas of the forests to be the same.

Answer:
8) 24 meters
9) 50.75 feet
10) 166 meters
Step-by-step explanation:
8) the perimeter is the sum of all sides of your shape. The shape is a rectangle, so you know 2 sides are the same length, 16.3 meters, and the other two sides are the size of the width, that is asked for.
so the perimeter = 2*length + 2*width which gives you the equation
80.6 = 2*16.3 + 2*x
then you solve it this way:
80.6 = 32.6 + 2x | substract 32.6 on both sides
48 = 2x | divide by 2 on both sides
24 = x
so you know the width is 24 meters
9) again, the perimeter is the sum of all 3 sides of your triangle.
2 sides are each 36 and 3 quarters feet long.
so the equation is perimeter = 2*36 3/4 + unknown side, giving you the equation
124 1/4 = 2 * (36 3/4) + x
124.25 = 73.5 + x | substract 73.5 on both sides
50.75 = x
so the third side is 50.75 feet (or in other writing 50 and 3/4 feet)
10) so on the image you see that the park is a triangle. you are given the area and one side (along Second Ave) and you need to figure out the length of the side along Front Street. When you "double" the triangle, you get a rectangle.
The area of the imagined rectangle is 2 times the area of the triangle (the park), so the area of our rectangle is 13778.
The area of a rectangle is calculated width * length.
This gives you the equation
13778 = 83 * x | divide both sides by 83
166 = x
So the length of the park along Front Street is 166 meters.

Answer:
The answer is [tex]\frac{13}{30}[/tex].
Step-by-step explanation:
Solve by completing fraction division.
Thus, solve [tex]\frac{5}{6} - \frac{2}{5}[/tex], since [tex]\frac{5}{6}[/tex] is larger than [tex]\frac{2}{5}[/tex].
[tex]\frac{5}{6} - \frac{2}{5}[/tex]

A new health drink has 130% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 20 mg. How many milligrams of the vitamin are in the drink?
Answer: 58.5 milligrams
Step-by-step explanation:
Answer:
58.5 mg
Step-by-step explanation:
Drink: 130% of RDA of vitamin X
RDA vitamin X = 45 mg
130% of 45 = mg in the drink
130% = 130/100 = 1.3
130% of 45 = 1.3 * 45 = 58.5
Thus, this new drink has 58.5 mg of vitamin.

What is an estimate?
An estimate is a rough calculation based on available information or rounded-off data.
Estimates are made to enable quick decisions without knowing complete details.
For this estimate, we used the division operation to obtain the quotients that should be the share of receiving families from each food category.
Original Data:
Food Item Number of Pounds Number of Families
Available Receiving Item
Chicken rolls 113.4 9
Mashed potatoes 6.6 12
Corn 28.5 10
Green bean 18.92 11
