Even smoking a few cigarettes a day or smoking occasionally increases the risk of lung cancer.
Are Transformations used to create Similar Figures EXPLAIN
Answers:
Sometimes, Never, Always,
Answer:
sometimes
Step-by-step explanation:
Similar figures can also be a different size, as long as they're the same shape. So both rigid transformations and dilations can create similar figures.
Let d(t) be the total number of .
Use one or more transformations to transform the pre-image (purple) onto the image (white).
Translate Rotate
* Reflect
(You cant tpuch the grey lines )
Answer: This is a translation of 12 units to the right.
translation written (x,y) -> (x+12,y+0)
Step-by-step explanation:
Pick a point on the pre-image, and count how many squares it has to move to end up at the corresponding point in the image.
Add that value to the coordinate x for horizontal movement, here +12.
Add to the coordinate y for vertical movement. here 0.
Determine whether each statement about the design from the rug is true.
Ashti is designing a rug that uses shapes to tell a
story, similar to what rug weavers in her culture
have done for generations. She uses a computer
program to dilate the shapes for the design of the
rug. One of Ashti's designs is shown below with
labels for figures 1 and 2 and points X, Y,and Z.
Select True or False for each statement.
The center of dilation for figures 1 and 2 is point Y.

find the value of the variable (3p-6)
Answer:1/3
Step-by-step explanation:
3p- -5=6
- and - becomes +
3p+5=6
transpose 5 to the other side
3p=6-5
because on transposing + becomes -
3p=1
p=1/3
because multiplication changes to addition on transposing

The lateral surface area of a cube is 400cm². Its total surface area is
_______
a)600cm² b) 2400cm² c) 500cm² d) 650cm²
Answer:
Step-by-step explanation:
Lateral surface area of cube = 4a²
4a² = 400
a² = 400÷4
a² = 100
a = √100 = √10*10
a = 10 cm
Total surface area = 6a²
= 6 * 10²
= 6* 100
= 600 cm²
Answer:
A

I believe that I did this before.
3x + 4y = 17 Solve for y Explain how to solve the problem please
Answer:
y = 17/4 - 3/4x
Step-by-step explanation:
[tex]3x + 4y = 17[/tex]
Subtract 3x from both sides.
[tex]4y = 17 - 3x[/tex]
Divide by 4 from both sides to isolate y.
[tex]y = \frac{17 - 3x}{4} [/tex]

what is the slope of the line that passes through the point (10,3) (2,3) write your answer in simplest form
Answer:
0
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
so m= (3-3)/(2-10)
m=0/-8
since 0 divided by anything is 0, the answer is 0

If a lizard can run 8 m across the water in 4 seconds, how
fast is he traveling?
Answer:
2 meters/second
Step-by-step explanation:
Equation for speed is:
s = d/t
Plug in the 8m for distance(d)
Plug in the 4 seconds for time(t)
So now you have s = 8m/4sec
This simplifies to s = 2 m/sec

A construction company orders tile flooring for the kitchen and three bathrooms of a new home. The kitchen floor measures 48 square feet. Two bathrooms have floors that each measure square feet. The third bathroom floor measures square feet. If the tile costs $2.39 per square foot, what's the least amount of money, to the nearest cent, the company spends on tile for all three bathrooms
Step-by-step explanation:
The question is incomplete. Let us assume the two bathrooms have floors that each measure 24 square feet and third bathroom floor measures 18 square feet.
For the two bathrooms, the total area will be 2*24 = 48 square feet
Since the third bathroom measures 18 square feet, the total square feet for the 3 bathrooms is equal to 48sq. ft + 18 sq.ft = 64sq. ft
If the tile costs $2.39 per square foot, then the amount that 64sq. ft tiles will cost is expressed as:
1 sq. ft = $2..39
64sq.f = $x
Cross multiply:
1*x = 2.39* 64
x = $152.96
Hence the amount that the company's spent on tiles for the three bathrooms will be 15296 cents.
Note that the dimensions of bathrooms were assumed. You can follow the same procedure for any dimension given.

What is the solution to the linear equation?
4b + 6 = 2 – b + 4
Answer:
b = 0
Step-by-step explanation:
Subtract 6 from both sides:
4b = 2 - b - 2
Subtract 2 from two, and get 0.
4b = -b
this means that the only possible case where the equation is satisfied is when b = 0, because -0 is 0, and 4x0 is still 0.
My teacher asked me to round 12,800 to the nearest thousand. I think that the answer is 13,000. Did I round correctly?
