Answers
First, you divide 12 by 3, giving you 4.
Then you divide a^3 by a^2, which is basically just subtracting the exponents, giving you a. Do the same with the rest of the variables. That’s how you get 4ab^2.

(7/5 , 7/5)
Equation Form: x = 7/5, y = 7/5Answer:
2y = -3x + 7
Step-by-step explanation:
(3, -1) and (-1, 5)
Slope:
m=(y2-y1)/(x2-x1)
m=(5+1)/(-1-3)
m=6/(-4)
m= -3/2
Slope-intercept:
y - y1 = m(x - x1)
y + 1 = -3/2(x - 3)
y + 1 = -3/2x + 9/2
y = -3/2x + 7/2
Standard form:
y = -3/2x + 7/2
3x + 2y = 7
2y = -3x + 7
Donna is putting down tile on her outdoor deck. The shape of her deck is shown below. Each unit on the coordinate plane represents 5 feet. Find the area of flooring needed in square feet.
Round your final answer to the nearest tenth.
Answers
The given area presented on the coordinate plane has dimensions
given by the lengths of the line joining the vertices.
Response:
The area of the flooring needed is 13.5 ft²How can the area of the shape be calculated?The given figure can be taken as a composite figure of wo triangles and
a trapezium.
Area of the triangle at the top, A₁ = 0.5 × 4.5 × 1 = 2.25
Area of the trapezoid, A₂ = 0.5 × (6 + 4.5) × 1 = 5.25
Area of the bottom triangle, A₃ = 0.5 × 2 × 6 = 6
Therefore;
Area of the figure, A = A₁ + A₂ + A₃
Which gives;
A = 2.25 + 5.25 + 6 = 13.5
Area of the flooring needed, A = 13.5 ft²

Step-by-step explanation:
Let x = number of hours.
Let y = cost.
The fixed cost is $11.
The cost per hour is $2.
For x hours, the cost per hour is 2x.
y = 2x + 11
23 = 2x + 11

a metal box that is in shape of cuboid has the following dimensions. the length is 9 inches, width is 2 inches and height is 1. 5 inches. find the total cost of silver coating the entire box if the cost of coating is $2.50 per Sq. inches
Answers
Given:
Length of a box is 9 inches, width is 2 inches and height is 1.5 inches.
The cost of silver coating is $2.50 per sq. inches.
To find:
The total cost of silver coating for the box.
Solution:
The total surface area of a cuboid is
[tex]A=2(lb+bh+hl)[/tex]
Where, l is length, b is breadth and h is height.
Putting [tex]l=9,b=2,h=1.5[/tex], we get
[tex]A=2(9\times 2+2\times 1.5+1.5\times 9)[/tex]
[tex]A=2(18+3+13.5)[/tex]
[tex]A=2(34.5)[/tex]
[tex]A=69[/tex]
So, the total surface area of the box is 69 square inches.
Cost of silver coating is $2.50 per sq. inches. So, the cost of silver coating for the box is
[tex]Cost=69\times 2.50[/tex]
[tex]Cost=172.50[/tex]
Therefore, the cost of silver coating for the box is $172.50.

Step-by-step explanation:
For a), there is a shaded region for where 15 is, and the number line is going towards the left, so x will be less than but also equal to 15
For b), there is not a shaded region for where 16.5 is, but the number line is going towards the right, so x will be greater than 16.5
For c), there is not a shaded region for where 34.5 is, but the number line is going towards the left, so x will be less than 34.5
For d), there is not a shaded region for where 23 is, but the number line is going everywhere else so it is x =/= 23(x does not equal to 23)

A rectangle lengths 12m and 17m and is dilated using the dilation (x, y) -> ( 0.4 x, 0.4y). What is the perimeter of the dilated rectangle?
Answers
Answer:
Perimeter of the dilated rectangle = 23.2 m
Step-by-step explanation:
If a point is dilated by a scale factor = k
Coordinates of the image point after dilation will follow the rule,
(x, y) → (kx, ky)
From the given rule,
(x, y) → (0.4x, 0.4y)
Which reveals that the figure has been dilated by a scale factor = 0.4
Length of the rectangle = 12 m
Width of the rectangle = 17 m
If the given rectangle is dilated by a scale factor of 0.4,
Length of the image rectangle = 12 × 0.4 = 4.8 m
Width of the image rectangle = 17 × 0.4 = 6.8 m
Perimeter of a rectangle = 2(length + width)
Therefore, perimeter of the image rectangle = 2(4.8 + 6.8)
= 23.2 m
