A dress was reduced from $180 to $162.
Express the discount as a % of the original price.
Answer: 90%
Step-by-step explanation:
When 180 is multiplied by 0.90, representing 90%, you get 162 :) So the item was discounted by 10% and is now 90% of it's initial amount
Answer: The original price was discounted by 10%
Step-by-step explanation:
180-162 = 0.1
1-0.1= 0.9
0.9 * 100= 90%
100% -10%= 90%
90% * 180= 162

19. Bella is putting down patches of sod
to start a new lawn. She has 20 square
yards of sod. Give the dimensions of two
different rectangular regions that she can
cover with the sod. What is the perimeter
of each region?
Answer:
The dimensions of the two different rectangular regions are;
1st Arrangement:
W = 4 yards and L = 5 yards or W = 5 yards and L = 4 yards
2nd Arrangement:
W = 2 yards and L = 10 yards or W = 10 yards and L = 2 yards
The perimeter of the two different rectangular regions are;
1st Arrangement:
P₁ = 18 yards
2nd Arrangement:
P₂ = 24 yards
Step-by-step explanation:
Bella is putting down patches of sod to start a new lawn.
She has 20 square yards of sod.
We are asked to provide the dimensions of two different rectangular regions that she can cover with the sod.
Recall that a rectangle has an area given by
Area = W*L
Where W is the width of the rectangle and and L is the length of the rectangle.
Since Bella has 20 square yards of sod,
20 = W*L
There are more than two such possible rectangular arrangements.
Out of them, two different possible arrangements are;
1st Arrangement:
20 = (4)*(5) = (5)*(4)
Width is 4 yards and length is 5 yards or width is 5 yards and length is 4 yards
2nd Arrangement:
20 = (2)*(10) = (10)*(2)
Width is 2 yards and length is 10 yards or width is 10 yards and length is 2 yards
Therefore, the dimensions of two different rectangular regions are;
1st Arrangement:
W = 4 yards and L = 5 yards or W = 5 yards and L = 4 yards
2nd Arrangement:
W = 2 yards and L = 10 yards or W = 10 yards and L = 2 yards
What is the perimeter of each region?
The perimeter of a rectangular shape is given by
P = 2(W + L)
Where W is the width of the rectangle and and L is the length of the rectangle.
The perimeter of the 1st arrangement is
P₁ = 2(4 + 5)
P₁ = 2(9)
P₁ = 18 yards
The perimeter of the 2nd arrangement is
P₂ = 2(2 + 10)
P₂ = 2(12)
P₂ = 24 yards
So the perimeter of the 1st arrangement is 18 yards and the perimeter of the 2nd arrangement is 24 yards.
Note:
Another possible arrangement is,
20 = (1)*(20) = (20)*(1)
Width is 1 yard and length is 20 yards or width is 20 yards and length is 1 yard.

The diagram shows a geometric figure on a coordinate plane. The figure is translated left two units and then reflected over the X axis, what are the ordered pairs for A' B' C'. Enter you answer in the format: (A’—,—), (B’—,—), (C’—,—)
Answer:
A'(3, 1), B'(3, -2), C'(1, -2)
Step-by-step explanation:
A(-1,1), B(-1, -2), C(1, -2)
A(-3, 1), B(-3, -2), C (-1, 2)
A'(3, 1), B'(3, -2), C'(1, -2)
A geometric figure on a coordinate plane with points. The figure is translated left two units and then reflected over the X axis. The ordered pairs of A, B, C are A (3, 1), B (3,-2), C (1, -2).
What is geometric figure?"A geometric figure is intuitively defined as a set of points and lines in space."
What is coordinate plane?"The coordinate plane is a two-dimension surface formed by two number lines. One number line is horizontal and is called the x-axis. The other number line is vertical number line and is called the y-axis. The two axes meet at a point called the origin. We can use the coordinate plane to graph points, lines, and more."
We have
A geometric figure on a coordinate plane with points
A = (1, -1)
B = (-1, -2)
C = (1, -2)
The figure is translated left two units and then reflected over the X axis
A drawn figure is attached to the answer
From the figure, we have
Figure is translated left two units
A = (-3 ,1)
B = (-3, -2)
C = (-1, -2)
Then the figure is reflected over x-axis
A = (3, 1)
B = (3,-2)
C = (1, -2)
Hence, The figure is translated left two units and then reflected over the X axis. The ordered pairs of A, B, C are A (3, 1), B (3,-2), C (1, -2).

What is the value of [-4.6]? –5 –4.6 –4.5 –4
Answer:
Out of your 4 options, it's -4.6
Step-by-step explanation:
The value of [-4.6] is -4. so option D is correct.
How to find the value of the ceiling function?We need to find the value of the ceiling function: [-4.6]
As we already know that the ceiling function always occupy the higher value in integers.
i.e. the ceiling function act as follows:
it takes value 0 when -1< x≤0
1 when 0 < x ≤ 1
2 when 1 < x ≤2.....and so on.
As we know that:
-4.6 lie between -5 and -4.
Hence, we get the value of [-4.6] is -4. so option D is correct.

5,888,000,000,000 miles is equivalent to 1 light year. What is this number represented in scientific notation?
Answer:
5.888x10^12
Step-by-step explanation:
First you got to make the number a decimal, but it can't be above 10 or below 1. So, we end up with 5.888000000000. Then, to get rid of all the zeros, we use the x10^12. The exponent is basically how many times the decimal has to move back to the right to get the original number.
A 13 ft ladder is resting on a wall. The angle the ladder makes with the floor is 45 degrees. How high off the ground is the top of the ladder?
Use the function y=13cos(theta) to find the answer
Answer:
9.19ftStep-by-step explanation:
The set up given will form a right angled triangle with the length of the ladder as the hypotenuse and distance between the the floor and the top of the ladder as the adjacent side to one of the acute angle 45 degrees.
Using one of the trigonometry identity to calculate How high off the ground the top of the ladder. According CAH;
cos 45° = Adjacent/Hypotenuse
cos45° = y/13
y = 13cos45°
y = 9.19ft
The ladder is 9.19ft off the ground
If f(x) = 2x2 and g(x)= x2 + 2x, which expression represents f(g(x))?
Answer:
f(g(x)) = 2(x^2 + 2x)^2
f(g(x)) = 2x^4 + 8x^3 + 8x^2
Step-by-step explanation:
Given;
f(x) = 2x^2
g(x) = x^2 + 2x
To derive the expression for f(g(x)), we will substitute x in f(x) with g(x).
f(g(x)) = 2(g(x))^2
f(g(x)) = 2(x^2 + 2x)^2
Expanding the equation;
f(g(x)) = 2(x^2 + 2x)(x^2 + 2x)
f(g(x)) = 2(x^4 + 2x^3 + 2x^3 + 4x^2)
f(g(x)) = 2(x^4 + 4x^3 + 4x^2)
f(g(x)) = 2x^4 + 8x^3 + 8x^2
