There are 19 oak trees in a park. Workers will plant more oak trees today. When the workers are finished there will be 56 oak trees in the park. How many oak trees did they plant today?
Given:
There are 19 oak trees in a park.
There will be 56 oak trees in the park the plantation.
To find:
How many oak trees did they plant today?
Solution:
We have,
Initial number of oak trees = 19
Number of trees after plantation = 56
Now, the number of oak trees they plant today is
New trees = Number of trees after plantation - Initial number of oak trees
= 56 - 19
= 37
Therefore, they did plant 37 oak trees today.

Suppose that 2000 is invented at a rate of 3.5%, compounded semiannually. Assuming that no withdrawals are made, find the total amount after 4 years. Do not round any interminate computations, And round your answer to the nearest cent.
Answer:
$2,297.76
Step-by-step explanation:
Present value: P = 2000
Future value: F
Annual interest rate: r = 3.5% = 0.035
Time: t = 4 years
Number of compounding periods per year: n = 2
[tex] F = P(1 + \dfrac{r}{n})^{nt} [/tex]
[tex] F = 2000(1 + \dfrac{0.035}{2})^{2 \times 4} [/tex]
[tex] F = 2000(1 + 0.0175)^{8} [/tex]
[tex] F = 2000(1.0175)^{8} [/tex]
[tex] F = 2000(1.148881783) [/tex]
[tex] F = 2297.76 [/tex]

Here the question wants to find the range of function. Your answer is incorrect because you are confusing between range and domain.
What is domain?Domain is the set of all x-values. That means any values that are part of x are subset of domain itself. We can find domain two ways which are
Relation methodGraph methodBut we are not talking about domain as we are looking for the range of function.
What is range?Range is the set of all y-values. In the relations or ordered pairs (x, y). Our y is the range. Range can also be called Co-Domain or Output. But of course, we are not talking about finding range using relation method. We are going to find range by looking at the graph.
The range starts from minimum value to maximum value. If there is another point between minimum value and maximum, just ignore it.
Here is a diagram or easier way to understand.
[tex] \boxed{minimum} \Longrightarrow \boxed{maximum}[/tex]
From the graph, our minimum is -5 and our maximum is -1. Notice that there is another opened point at -2 which we are supposed to ignore. Because both minimum and maximum are closed dots. Hence, we use >= or <= only.
Therefore the solution should be
[tex] - 5 \leqslant y \leqslant - 1[/tex]
Answer[tex] - 5 \leqslant y \leqslant - 1[/tex]
......the correct answer is A

Write an equivalent expression by distributing the "-−" sign outside the parentheses:
-(-1.5q+5r)+2
Answer:
1.5q - 5r = 2
Step-by-step explanation:
All you need to do here is negate each term inside the brackets, which allows you to get rid of the minus sign and the brackets.
-(-1.5q + 5r) = 2
is exactly the same as saying:
-1 × (-1.5q + 5r) = 2
And if we multiply each term in the brackets by negative one, we get:
(1.5q - 5r) = 2
And now the brackets can go, leaving you with:
1.5q - 5r = 2

List all the possible outcomes of the 3 throws.
Given:
Mason throws a coin 3 times.
The outcome of each throw is either Heads or Tails.
To find:
The list of all the possible outcomes of the 3 throws.
Solution:
Let H represents heads and T represents tails.
For each throw we have 2 choices either H or T.
For three throws the total number of possible outcomes is
[tex]2^3=8[/tex]
Now, list the possible outcomes as shown below.
HHH, HHT, HTH, HTT, THH, THT, TTH, TTT
Therefore, the list of 8 possible outcomes is HHH, HHT, HTH, HTT, THH, THT, TTH, TTT.

To stock your school store, you buy a total of 25 sweatshirts and hats for $172.50. You pay $8.00 per sweatshirt and $2.50 per hat. How many of each item do you buy?
Answer:
the answer is 20 and 5
Step-by-step explanation:
Number of hats is 5 and the number of sweatshirts is 20
The total number of items bought is 25
The total amount is $172.50
Let a represent the number of sweatshirts
Number of hats is 25-a
Cost of sweatshirt= 8x
Cost of hat= 2.50×(25-x)
= 62.50-2.5x
8x + 62.50 - 2.5x-172.50
8x-2.5x+62.50-172.50
5.5x -110
5.5x= 110
x= 110/5.5
= 20
Number of hats= 25-20, = 5
Number of sweatshirts= 20

Given that ΔABC ∼ΔDEF, m∠A = 108 degrees and m∠E = 40 degrees. Find m∠F. Type ONLY the number of degrees.
Answer:
∠F = 32°
Step-by-step explanation:
ΔABC & ΔDEF are similar triangles. So, corresponding angles of both triangles are congruent
∠D = ∠A = 108
∠B = ∠E = 40
∠C = ∠F
In ΔDEF,
∠D +∠E + ∠F = 180 {Angle sum property of triangle}
108 + 40 + ∠F = 180
148 +∠F = 180
∠F = 180 - 148
∠F = 32°

Find the area of the shape below giving your answer to 1 decimal place.
Answer:
198.5 cm²
Step-by-step explanation:
From the figure above we can treat the two semi circles as 1 circle.
Now, the diameter is 10 cm
Thus;
Radius; r = 10/2
r = 5cm
Now, formula for area of a circle is;
A = πr²
Thus;
Area of 2 semi circles = Area of 1 circle = π × 5²
A_circle = 78.54 ≈ 78.5 cm²
When we take out the 2 semi circles, what we have left is a rectangle.
Now, the length of the rectangle will be;
Length; L = 22 - 5 - 5 = 12 cm
*This is because the radius of the semi circle is 5 and distance from the edge of the 22 cm length to the centre of the semi circle is 5 cm
Thus, area of rectangle is given by;
A_rect = LW
W in the image is 10 cm
Thus;
A_rect = 12 × 10
Total area of shape is;
A_total = 120 + 78.5
A_total = 198.5 cm²
Find the area of the following circle. 6 cm

X=
DONE
Answer:
x=−2
Step-by-step explanation:
Simplify both sides of the equation.
3(−x+2x+1)=x−1
Distribute
(3)(−x)+(3)(2x)+(3)(1)=x+−1
−3x+6x+3=x+−1
Combine Like Terms
(−3x+6x)+(3)=x−1
3x+3=x−1
3x+3=x−1
Subtract x from both sides.
3x+3−x=x−1−x
2x+3=−1
Subtract 3 from both sides.
2x+3−3=−1−3
2x=−4
Divide both sides by 2.
2x/2=−4/2
x=-2
