Answer:
Step-by-step explanation:
Perimeter of the square is 24(4)=96.
Perimeter of the rectangle is 2(10+length)=96
10+length=48
length=38 m
Area of the square is 24^2 = 576.
Area of the rectangle is 10 * 38 = 380
So the square has an area 196 m^2 greater.
a stock investment of 160 shares paid a dividend of $584 at this rate what dividend would be paid on 270 shares of stock
Answer:
4985.5
Step-by-step explanation:
To start, lets show what we know
160x = 584 where x is the amount paid per stock investment
Find: 270x
Now lets find x
160x = 584
160x/160 = 574/160
x = 3.65
270x = 270(3.65) = 985.5
Here, we have our answer of $985.5 for 270 shares of stock.

What is problem-solving?Problem-solving is the act of defining a problem; figuring out the purpose of the trouble; identifying, prioritizing, and selecting alternatives for an answer; and imposing an answer.
Problem-solving starts with identifying the issue. As an example, a trainer may need to parent out a way to improve a scholar's overall performance on a writing talent test. To do that, the instructor will overview the writing exams looking for regions for improvement.

The square on the right is a scaled copy of the square on the left. Identify the scale factor. Express your answer in simplest form.
Answer:
83/85
Step-by-step explanation:
85 is being multiplied by something to get to 83
85x = 83
x = 83/85
You cannot simplify this any further because it has no common factors.
-Chetan K
write the equation for the line in standard form
Step-by-step explanation:
a parallel line has the same slope (inclination).
the slope is always the factor of x in the line equation, which is 1/2.
the standard form of a line is
y = ax + b
we know a = 1/2.
to get b we use the given point :
-5 = 1/2 × -6 + b
-5 = -3 + b
b = -2
so our line equation is
y = (1/2)x - 2
but if your teacher understands "standard form" as "point-slope" form (I don't, but others do), then we need to use
y - y1 = a(x - x1)
where (x1, y1) is a point on the line.
and that form would then be in our case
y - -5 = (1/2)(x - -6)
y + 5 = (1/2)(x + 6)
Beatrice has at least one quarter, one dime, one nickel, and one penny. She has exactly 13 coins total. Beatrice also has a total value of 92 cents. How many different sets of coins can she have?
The number of different sets of coins that she can have is; Two sets which are; (0, 7, 4, 2) or (1, 3, 7, 2)
What is the combination of coins?Let the numbers of coins be;
Quarter; QDimes: DNickel; NPenny; PWe have:
Q + D + N + P = 13
We know that;
25 quarters make 1 cent
10 dimes makes one cent
5 nickels make one cent
1 penny makes one cent
Thus;
25Q + 10D + 5N + P = 92
P will have to be 2 because the others will give a value with the unit digit as 0. Thus;
Q + D + N = 11 ----(1)
25Q + 10D + 5N + 2 = 92
25Q + 10D + 5N = 90
Divide through by 5 to get;
5Q + 2D + N = 18 (2)
Subtract eq (1) from eq (2) to get;
4Q + D = 7
Let us put D = 7 and Q = 0, and so from eq (1), N = 4
The set here is now; (Q, D, N, P) = (0, 7, 4, 2)
Let us put D = 3, Q = 1, and from eq (1), N = 7
The set here is now; (Q, D, N, P) = (1, 3, 7, 2)
If D = 6, 5, 4, 2, 1, 0, then Q is not an integer, these can be ignored.

The ages of Fiona, Cara and Thomas is 17, 34 and 20 respectively.
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Fiona who is [x] years old. Thomas is 3 years older than Fiona. Cara is twice as old as Fiona the sum of their ages is 51.
We can write -
Age of Thomas = [y] = x + 3
Age of Cara = [z] = 2x
and
2x + x = 51
3x = 51
x = 17
Age of Thomas = [y] = x + 3 = 20
Age of Cara = [z] = 2x = 34
Therefore, the ages of Fiona, Cara and Thomas is 17, 34 and 20 respectively.

Evaluate (6 +2i) / (3-i).
Answer:
2(4 + 3i) / 5
Step-by-step explanation:
(6 + 2i) (3 + i) / (3 - i) (3 + i)
=> 18 + 12i + 2i² / 9 - i²
=> 16 + 12i / 10
=> 8 + 6i / 5
=> 2(4 + 3i) / 5
Answer:
(6 +2i) / (3-i) = (6+2i)/(3-i) x (3+i)/(3+i) = (6+2i)(3+i) / (3-i)(3+i) = 6(3+i)+2i(3+i) / (3)^2-(i)^2 = 18+6i+6i+2i^2 / 9-i^2 = 18+12i+2i^2 / 9-i^2 = 6+12i+2i^2 / 3-i^2 = 2+12i+2i^2 / 1-i^2 = 2+12i+2 / 1 = 4+12ianswer.

JKLM is a triangle. Find the measure of angle KL and JM
Answer:
x = 10
m∠K = 90°
y = 15
JM = 65
Step-by-step explanation:
KJ = LM
⇒ x + 31 = 5x - 9
⇒ 40 = 4x
⇒ x = 10
From inspection of the diagram, m∠K = 90° (right angle)
KL = JM
⇒ 4y + 5 = 2y + 35
⇒ 2y = 30
⇒ y = 15
JM = 2y + 35
⇒ JM = 2(15) + 35
⇒ JM = 30 + 35
⇒ JM = 65
