A museum sells postcards of famous paintings. The postcards must be the same shape as the painting.
Postcard C is the same shape as the painting because they are in the same proportion.
What is the similarity law?It is defined as the law to prove that the two figures have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.
It is given that:
A museum sells postcards of famous paintings.
Applying similarity law that states: The ratio of the corresponding sides is in the same proportions.
In poster A:
5/30.25 = 5/25.25
1/6.05 = 1/5.05
In the poster B:
8/30.25 = 4/25.25
1/3.78 = 1/6.312
In poster C:
6.05/30.25 = 5.05/25.25
1/5 = 1/5 (they are in the same proportion)
Thus, postcard C is the same shape as the painting because they are in the same proportion.

Step-by-step explanation:
if you add a negative and a negative it is still a negative. when you have a number minus a negative, it can be positive or a negative. you change the -(- to a + this is what I call chop slash. then you do -8 + 2 = -6 because you are at -8 and then go to the right of the number line 2 spaces. numbers 1 and 4 have the same rules and numbers 2 and 3 have the same rules.
Bill works for a company that makes candy bars. Bill's job is to pack 10 candy
bars in every box. Bill then places 12 boxes in a shipping carton. Each carton
shipped contains how many candy bars?
Answer:
120 bars
Step-by-step explanation:
If Bill packs 10 candy bars in every box and there are 12 boxes in every shipping carton, then that would mean there are 12 sets of 10 candy bars. Meaning that you would multiply 10 by 12 since there are 12 boxes and 10 candy bars in each box (which would give you 120).

a) The coefficient in the expression -3x + 1 is
Step-by-step explanation:
A coefficent is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. Or in other words, the number being multiplied with the variable. For example, the 4 in 4x.
The expression is -3x + 1. If we go back to the definition, the coefficient is the number combined with the variable.
So the answer is -3.

MATH
Answer:
Increase, Decrease
Step-by-step explanation:
A student standing on top of a building sees a bird flying that is 25ft away and 20 ft above the top of the building. The student also sees a car on the ground at and angle of depression 70°. The car is directly below the flying bird.A diagram of the situation is shown below
Answer: The height of the building is 41.2 ft
Step-by-step explanation:
Here we want to find the height of the building.
To do so, the first step is to find the horizontal distance between the student and the car/bird (which represents the common cathetus between the two triangle rectangles).
For the top triangle rectangle, we know one cathetus and the hypotenuse, and we can use the Pythagorean's theorem to find the other cathetus.
A^2 + B^2 = H^2
Where A and B are the cathetus, and H is the hypotenuse.
Then we have:
20^2 + B^2 = 25^2
B^2 = 25^2 - 20^2
B = √( 25^2 - 20^2) = 15
Then the horizontal distance between the student and the car is 15ft, and we also know the angle at which this cathetus is adjacent, the angle is 70°.
Then we can use the relationship:
Tan(A) = (opposite cathetus)/(adjacent cathetus)
Where the opposite cathetus woud be the height of the building, then:
Tan(70°) = H/15ft
Tan(70°)*15ft = H = 41.2 ft

In circle O shown below, the endpoints of the
diameter are (-2, 4) and (3, 1). What is the
length of the radius to the nearest tenth?
Answer:
2.9 units
Step-by-step explanation:
Length of the radius = ½ of the distance between the two endpoints
Distance between (-2, 4) and (3, 1) using the formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] (-2, 4) = (x_1, y_1) [/tex]
[tex] (3, 1) = (x_2, y_2) [/tex]
[tex] d = \sqrt{(3 - (-2))^2 + (1 - 4)^2} [/tex]
[tex] d = \sqrt{(5)^2 + (-3)^2} [/tex]
[tex] d = \sqrt{25 + 9} = \sqrt{34} [/tex]
[tex] d = 5.8 [/tex]
Length of radius = ½ of 5.8 = 2.9 units.

We are given with two decimal numbers. Compare the numbers and complete the blank by < or > or =
To compare the decimals , compare each digit from left to right
0 is equal to 0
4 is greater than 0
so we can say 0.40 is greater than 0.04
0.40 > 0.04
Both decimal numbers are not equal
Answer:
0.40 > 0.04

Is the 0.45 square root greater or lesser than 0.229
Answer:
0.45 is more
Step-by-step explanation:
:)
The square root of the number is √0.45 = 0.670 is greater than 0.229
Given data ,
Let the first number be represented as p
where the value of p = 0.45
Let the second number be represented as q
where q = 0.229
Now , the square root of the number is expressed as
A = √p
The radical form of a number refers to expressing a number using a radical symbol (√) to represent a root.
It is used to express the roots present in the number.
So , A = √0.45
On simplifying , we get
A = 0.670
And , the value of A > q
So , 0.670 > 0.229
Hence , the square root is A = √0.45 = 0.670
