In 2020, Forest A had an area of about 4000 acres and Forest B had an area of about 3600 acres. Researchers expect deforestation to cause the area of 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. In what year do they expect the areas of the forests to be the same?
Answers
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.

Based on the figure below, what is the value of x? (5 points)
A right angle is shown divided in two parts. The measure of the angle of one part is 50 degrees and the measure of the other part is 5x plus 15 degrees.
a 5
b 7
c 11
d 15
Answers
Answer: a. 5
Since the angle is right, we know it is equal to 90 degrees.
Using the information provided, we can set up an equation.
50 + 5x + 15 = 90
Simplifying the equation, we get:
5x + 65 = 90
Subtracting 65 from both sides, we get:
5x = 25
Dividing both sides by 5, we get:

Dan made a scale drawing of a summer camp. The scale of the drawing was 5 centimeters : 3 meters. The sand volleyball court is 9 meters wide in real life. How wide is the volleyball court in the drawing?
centimeters ______
Answers
Answer:
Step-by-step explanation:
9 divided by 3=3
3 times 5=15
To find the width of the volleyball court in the scale drawing, we set up a proportion using the scale (5cm : 3m) and the real-life width (9m). Solving the proportion (5cm : 3m = x : 9m) gives us a drawing width of 15cm.
Explanation:The first step to solve this problem is to set up a proportion. In Dan's drawing, 5 centimeters represents 3 meters in real life. So we can write the first ratio as 5cm : 3m. We know in real life the volleyball court is 9 meters wide, so to find out how wide it is in the drawing we set up the proportion 5cm : 3m = x : 9m. To solve for x, we cross multiply and divide. (5cm * 9m) / 3m = 15cm. Thus, the width of the volleyball court in the drawing is 15 cm.

Is Figure BBB a scale copy of Figure AAA?
Answers
Reason - if the scale factor of a and b was 2, the dimensions of a would be 4, 7.2 and 10 not the ones present on A
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
Here, we have to determine if Figure B is a scale copy of Figure A, we need to compare the corresponding sides of the two triangles and check if the ratios of their side lengths are equal.
Figure A has side lengths: 3.6, 2, and 5.
Figure B has side lengths: 8.9, 4, and 11.3.
Let's check if the ratios of corresponding side lengths are equal:
Ratio of corresponding side lengths of A and B:
3.6 / 8.9 ≈ 0.4045
2 / 4 = 0.5
5 / 11.3 ≈ 0.4425
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
In order for two triangles to be scale copies of each other, all corresponding side lengths must have the same ratio.
Since the ratios of side lengths in Figure A and Figure B are not equal, they are not scale copies of each other.

7th grade - Find the surface area of this trapezoidal prism. Please help ASAP I'll give brainliest!!!
Answers
Answer:
\(380 \text{ m}^2\)
Step-by-step explanation:
To find the surface area of the trapezoidal pyramid, we can use the formula:
\(SA = 2(b) + (p \cdot d)\),
where \(b\) is the area of the base, \(p\) is the perimeter of the base, and \(d\) is the prism's depth.
First, we should find the area of the base using the area of a trapezoid formula.
\(A_\text{trap} = \dfrac{b_1 + b_2}{2} \cdot h\)
\(b = \dfrac{15 + 5}{2} \cdot 7\)
\(b = 10 \cdot 7\)
\(b = 70 \text{ m}^2\)
Now, we can plug the given dimensions along with the base area into the surface area formula.
\(SA = 2(b) + (p \cdot d)\)
\(SA = 2(70) + ([15 + 10 + 5 + 10] \cdot 6)\)
\(SA = 140 + (40 \cdot 6)\)
\(SA = 140 + 240\)
\(\boxed{SA = 380 \text{ m}^2}\)

You want the area of icing on a cake that is 10 inches in diameter and 2 inches high.
IcingThe icing on a cake covers the lateral surface area and the area of the circular top. In terms of diameter, the sum of those areas is ...
icing area = πdh +(π/4)d² = πd(h +d/4)
icing area = π(10 in)(2 in + (10 in)/4) = π(10 in)(4.5 in)
icing area = 45π in² ≈ 141.4 in²
The area of icing on the cake is about 141.4 square inches.

The given relation is not a function because for each input (x-value), there is not exactly one output (y-value).
In a function, each input (x-value) should have only one corresponding output (y-value). However, in this relation, the input value of 1 has two different output values: -2 and 3. Therefore, it violates the definition of a function.
To illustrate this, let's look at the points (-2, 0), (1, -2), and (1, 3). The x-value of 1 appears twice in the relation, but it has two different y-values associated with it. This means that for the input value of 1, there is not exactly one output value, which is why the given relation is not a function.
In conclusion, the relation is not a function because for each input there is not exactly one output.

Answers
Answer: I'm not so sure but my answer is 54 or 55
Step-by-step explanation:
The probability of choosing a vowel is 30%, and there are 42 consonants, so we would set up an equation like this:
42 times 30% (0.30) = 12.6 (rounded to 12)
So we have 12 vowel and 42 consonants in the bag, the total tiles would be:
12+42= 54
* But in case your teacher rounded up to 13 (vowels), the answer should be 55. But the probability rounded up to 13 is very low.
