Answer:
nah
Step-by-step explanation:
1/5x means x can be any varible plus 2, and 1/5 (x +2) means that you multiply 1/5 by x then add 2.
Answer:
No
Step-by-step explanation:
because [tex]\frac{1}{5\\\\}[/tex]x +2 is not the same as [tex]\frac{1}{5\\}[/tex](x+2)
The perimeter of an equilateral triangle is 63 inches. If the length of each side is (4x-3), find the value of x.
Hint: Triangles have 3 sides.
What is the scale factor of the dilation?
Is the dilation an enlargement or a reduction?
Answers:
Scale Factor = 3/4
This is a reduction
======================================================
Explanation:
Let's focus on the point R(4,4). That's the preimage point for the image of R ' (3,3).
Let k be the scale factor. We multiply this value of k by the x,y coordinates of point R to jump to R '
we have x = 4 jump to 4k which is the x coordinate of point R'
So we set 4k equal to 3 and solve for k to get k = 3/4. The scale factor is 3/4 or 0.75
We have a reduction since the image triangle T'R'S' is smaller compared to the preimage triangle TRS. We can see that we have a reduction by looking at the scale factor. If 0 < k < 1, then we have a reduction. If k > 1, then we have an enlargement instead. So we go with the first option since 0 < 3/4 < 1 or you could say 0 < 0.75 < 1.
Answer:
A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement is a dilation that creates a larger image

18 = 0/10
19 = 13/10
20 = 13/10
Solve the x
-9 (1/2x - 3) = 45
Answer:
=
−
3
6
7
Step-by-step explanation:
Answer:
x = -4
Step-by-step explanation:
-9 (1/2x - 3) = 45
Divide both sides by -9
1/2x - 3 = -5
Add 3 to both sides
1/2x = -2
multiply both sides by 2
x = -4

Match the verbal statement to the correct value.
One–third of the product of −8 and 9
Half the sum of 8 and −6
Three times the sum of 12 and −6
One-fifth the product of 1 and −5
Five times the sum of −8 and 4
Answers:
-24
-20
-1
1
18
Answer:
down below.
Step-by-step explanation:
One–third of the product of −8 and 9 = -24
-8(9) = -72
-72 / 3 OR -72(1/3) = -24
Half the sum of 8 and −6 = 1
8 + (-6) =2
2 / 2 = 1
Three times the sum of 12 and −6 = 18
12 + (-6) = 6
6 * 3 = 18
One-fifth the product of 1 and −5 = -1
1(-5) = -5
-5/5 = -1
Five times the sum of −8 and 4 = -20
-8 + 4 = -4
-4 * 5 = -20

Ophelia keeps flour in a cylindrical canister. The capacity of the full canister is 75.36 in^3..When it is filled halfway the flour reaches a height of 3 in. What is the diameter of the canister?
Answer:
4 (rounded to the nearest whole number)
Step-by-step explanation:
total height = 3 x 2 = 6
Volume = radius^2 * pi * height
75.36= radius^2 * pi * 6
75.36/pi = radius^2 * 6
23,987833 = radius^2 * 6
23,987833/6 = radius^2
3,997972 = radius^2
radius = 1,999493
diameter = radius x 2 = 1,999493 x 2 = 3,998986
In what periods are the lanthanides and actinides? Where are they
placed in the periodic table? Why?

the sides of a rectangle are in the ratio 2:5. if the longer side of the rectangle is 25.5 in., what are it's width, perimeter, and area ?
Answer: The width of the rectangle is 10.2 inches, the perimeter is 71.4 inches, the area is 260.1 inches.
Step-by-step explanation:
25.5/5=5.1
5.1*2=10.2
The width is 10.2 inches
25.5*2+10.2*2=71.4
The perimeter is 71.4 inches
20.5*10.2=260.1
The area is 260.1
Width=10.2 in. Perimeter=71.4 in. Area=and 260.1 in.

Can someone give me a small lesson on nets and surface areas??
Thank you if you can. I really don’t understand.
Hi!
Here is the definition of a net from www.icoachmath.com:
“Net is a two-dimensional pattern of a three-dimensional figure that can be folded to form the figure. In other words, net is a flattened three-dimensional figure which can be turned into the solid by folding it.”
In the photo is an example of a net of a rectangular prism.
Surface area is the measure of the total area of the surface of a 3D object. For example, if I have a cube, the surface area would be the area of the outside of the cube.
