Perimeter of ΔA'B'C' is 52 cm.
The perimeter of ΔABC is =13 cm
Length of OB = 5 cm
Length of OB' = 15 + 5 = 20 cm
The Dilation factor can be found out b
ΔOCB and ΔOC'B' are similar as BC|| B'C'
From triangles ΔOCB & ΔOC'B' the dilation factor can be found out
by the formula below
[tex]\frac{BC}{B'C'} =\frac{5}{20}[/tex]
B'C'= 4BC
so the dilation factor = 4
hence the new perimeter of the triangle = 13 4 = 52 cm

Answer:
405π
Step-by-step explanation:
Use the formula for Volume Of Cylinder (V=πr²h) where "V" represents the volume, "r" represents the radius, and "h" represents the height
The volume and the radius are given. (V=45π, r=3)
1. Solve for height
V=πr²h
45π=π3²h
45π/π=3²h
45=3²h
45=9h
45/9=h
h=5
2. Plug the new radius (3*3=9) into this formula and solve for "V"
V=π9²5
V=π81*5
V=405π
NEW VOLUME AFTER A TRIPLED RADIUS IS 405π

How do you solve this URGENT (50pts)
Explanation:
x + 3y = 2
Converting it to slope intercept form:
y = mx + b [where m is slope, b is y-intercept]
Make y the subject:
[tex]\sf \rightarrow 3y = 2 - x[/tex]
[tex]\sf \rightarrow 3y = -x + 2[/tex]
[tex]\sf \rightarrow y = -\dfrac{x}{3} + \dfrac{2}{3}[/tex]
[tex]\sf \rightarrow y = -\dfrac{1}{3} x+ \dfrac{2}{3}[/tex]
which reveals slope:
[tex]\star \ slope: \sf - \dfrac{1}{3}[/tex]
Answer:
slope = - [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
x + 3y = 2 ( subtract x from both sides )
3y = - x + 2 ( divide all terms by 3 )
y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{2}{3}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{1}{3}[/tex]

A, C and D are points on a circle of radius 4 cm, centre O. BA and BC are tangents to the circle. 4 cm, OB = 10 cm D O 4 cm Work out the length of arc ADC. Give your answer correct to 3 significant figures. B
Without cos, please and thank you!
By applying trigonometric reasons, Pythagorean theorem and the definition of circle arc, the measure of the arc ADC is approximately 15.858 centimeters.
How to determine the arc of a system formed by a circle and two symmetrical right triangles
Since AB and BC are tangent to the circle, then the triangles OAB and OBC are right angled. We can determine the measure of the angle AOC by using the following inverse trigonometric reason and Pythagorean theorem:
[tex]\theta = 2\cdot \tan^{-1}\left(\frac{\sqrt{10^{2}-4^{2}}}{4} \right)[/tex]
θ ≈ 132.844°
And the measure of the arc ADC is found by the formula for the length of a circle arc:
s = θ · r (1)
Where:
θ - Central angle, in radiansr - Radius, in centimeterss = (2π - 132.844π/180) · (4 cm)
s ≈ 15.858 cm
By applying trigonometric reasons, Pythagorean theorem and the definition of circle arc, the measure of the arc ADC is approximately 15.858 centimeters.

The length of a rectangle is 6 yd longer than its width. If the perimeter of the rectangle is 60 yd, find its length and width.
Answer:
Length: 18 yards Width: 12 yards
Step-by-step explanation:
Perimeter = (L+W) x 2
L = W + 6
60 yd = (W+W+6) x 2
30 yd = 2W + 6
24 yd = 2W
W = 12
L = 12 + 6 = 18

Step-by-step explanation:
Given equation:

Expand the brackets:
[tex]\implies \dfrac{2}{5}(10y)-\dfrac{2}{5}(5)-2y=-10[/tex]

Joseph needs to buy insulation for the inside of a truck container. The container is a rectangular prism 12 feet long, 7 feet wide, and 6.5 feet high. How much insulation should Joseph buy if all surfaces except the floor are to insulated?
Answer:
Joesph needs to be 331 feet of flooring to cover all sides except the floor.
Step-by-step explanation:
To answer this question, you need to find the areas of the sides and the roof.
Side (left and right): 12 feet long multipled by 6.5 feet high. 12*6.5=78 ft^2. Multiply this by 2 to get the combined areas of both the left and right side. 156 ft ^2
Side (back and front): 7 feet wide by 6.5 feet high. 7*6.5=45.5 ft^2. Multiply this by two to get the combined areas of the back and the front sides. 91 ft^2
Roof: 7 feet wide multiplied by 12 feet long. 7*12=84 ft^2
84+91+156=331 ft^2
Answer:
331 ft²
Step-by-step explanation:
Area of a rectangle = width × height
Given:
base width = 7 ftbase length = 12 ftheight = 6.5 ftSurface area (minus the floor):
= 2(7 × 6.5) + 2(12 × 6.5) + (7 × 12)
= 91 + 156 + 84
= 331 ft²

In order for the function to be linear, what must a be and why?
a = 22 because the rate of change is 1.
a = 20 because the rate of change is 3.
a = 22 because the rate of change is –1.
a = 20 because the rate of change is –3.
For the function to be a linear, D. a = 20 because the rate of change is –3.
What is the Rate of Change of a Function?The rate of change = change in y / change in x.
Therefore, for the function to be linear, the rate of change must be the same across the table of values.
Using, (4, 26) and (5, 23):
Rate of change = (26 - 23)/(4 - 5)
Rate of change = (3)/(1) = -3
Using (5, 23) and (6, a), we have:
(23 - a)/(5 - 6) = -3
(23 - a)/(-1) = -3
23 - a = (-3)(-1)
23 - a = 3
-a = 3 - 23
-a = -20
a = 20
Therefore, the answer is: D. a = 20 because the rate of change is –3.

Answer:
35 inches²
Step-by-step explanation:
Given Base and Height of triangle: 10 inches and 7 inches
To determine the area of a triangle, multiply the base and the height. Then divide the product of the base and the height by 2.
Therefore, the "area of triangle" formula is:
[tex]\boxed{\text{Area of a triangle} = \frac{\text{Base} \times \text{Height}}2}[/tex]
Now, substitute the base and the height in the formula. Then, simplify the expression to determine the area of the triangle provided.
[tex]\implies \text{Area of the triangle} = \dfrac{\text{10} \times \text{7}}2}[/tex]
[tex]\implies \text{Area of the triangle} = \dfrac{70}2} = \boxed{35 \ \text{in}^{2}}[/tex]

Step-by-step explanation on coordinates:
The coordinates indicate the position of a point in the 2D coordinate plane relative to the origin. The x-coordinate of a point is its perpendicular distance from the y-axis measured along the x-axis. The y-coordinate of a point is its perpendicular distance from the x-axis measured along the y-axis.
Coordinates are two numbers (Cartesian coordinates), or sometimes a letter and a number, that locate a specific point on a grid, known as a coordinate plane. A coordinate plane has four quadrants and two axes: the x axis (horizontal) and y axis (vertical).
Coordinates are written as (x, y) meaning the point on the x axis is written first, followed by the point on the y axis.
