Answer and Step-by-step explanation:
It's very easy.
If you have two shapes, let's say triangles, the shapes are said to be similar if the corresponding angles are equal. For instance a triangle ABC with angles A = 45, B = 45 and C = 90 if there is another triangle PQR with angles P = 45, Q = 45 and R = 90, we say triangle ABC and triangle PQR are similar because their corresponding angles are equal.
Two triangles are said to be congruent if they are exactly the same in angles and size. All congruent shapes are similar but not all similar shapes are congruent.
To find area of similar shapes, we need what we call the scale factor of the enlargement.
If we have two similar shapes where by one is an enlargement of the other. Let's say the enlargement is in ratio 2:1. This ratio 2:1 is what we call scale factor. If we want to find the area of one shape given the area of a similar one to it, we make use of
Area = (scale factor)². For instance if we have two similar triangles, the area of the bigger is 16cm² and the scale factor is 2:1, we can find the area or the smaller by:
(2/1)² = 16/X = 4/1 = 16/X
4x = 16 and x = 4.
To find volume we use:
Volume = (scale factor)³ and the process is the same.

In the linear equation shown, which variable would represent the output (range) values?
the answer should be y
Step-by-step explanation:
|•-•|
y would represent the output values.
What are different values in a linear equation of a straight line?
The equation y = mx + c is the general equation of any straight line where m is the gradient of the line (how steep the line is) and c is the y-intercept (the point in which the line crosses the y-axis).
y = mx + c is a linear equation and the variables x and y relate to coordinates on the line.
When we input a value for x into the equation y = mx + c, we get a result for y.
This means that x is an independent variable, and y is a dependent variable as it is determined by the value of x.

Answer:
This should be a simple math problem if I didn`t miss understand anything the answer should be 99000
Step-by-step explanation:
99000 I think
Answer:
99,000
Step-by-step explanation:
If there are 30 seats in each row, you must multiply 30 by the number of rows there is. There are 3300 rows. Therefore, the answer to 3300 x 30 would be 99000.

Find the nth term of this quadratic sequence 3 8 15 24
Answer:
35
Step-by-step explanation:
A quadratic sequence is a form. of mathematical progression of numbers in which the subsequent differences between each consecutive term differ by the exact amount. This is known as the common second difference.
Hence in this case,
we have
S= 3+8+15+24+…..+Tn - 1.
S=. 3+8+15+……………..Tn-1 + Tn
Deducting 2nd series from the first
We have 0=3+5+7+…….Tn
Hence, we have Tn= n (n+2)
= 24 (9+2)
= 24 + 11

Solve. Chanasia has 6.25 gallons of paint. She wants to use 2/5 of the paint to paint her living room. How many gallons of paint will Chanasia use?
Answer: 2.5 gallons
Step-by-step explanation:
Given that:
Gallons of paint had = 6.25 gallons
Amount needed to paint room = 2/5 of the paint
Gallons of paint needed :
2/5 of 6.25
(2 * 6.25) / 5 gallons
= 12.5 / 5
= 2.5 gallons
x = - 5
x ^ 2 + y ^ 2 = 25
show work also
Step-by-step explanation:
Since x is equal to -5, you would need to substitute that value for x in the equation x^2 + y^2 = 25. So....
-5^2 + y^2 = 25
(-5)*(-5) + y^2 = 25
25 + y^2 = 25
y^2 +25 - 25 = 25 - 25
y^2 = 0
y = 0
(x, y) = (-5, 0)
To check the answer....
x^2 + y^2 = 25
-5^2 + 0^2 = 25
25 + 0 = 25
25 = 25
The answer should be correct, if not i am extremely sorry

Answer:
C
Step-by-step explanation:
Given y = f(x) then y = f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Thus (x - 5)² is a shift to the right of 5 units
Given y = f(x) then y = f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Thus
y = (x - 5)² + 6
is the graph of y = x² translated 6 units up and 5 units to the right → C

Why is the percent increase from 45 to 75 not equal to the percent decrease from 75 to 45? Select three options.
UThe amount of change drent for the percent increase and the percent decrease
UThe ratio of the percent increase is not the same as the percent decrease.
OThe ratio for the percent increase has a smaller denominator than the percent decrease.
U The ratio for the percent increase has a different numerator than the percent decrease.
O The original amount for the percent increase is different from the original amount for the percent decrease.
Answer:
work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease.

Parallelograms s and t are each labeled with a base and a corresponding height
Answer:
Parallelogram S:
b = 7 and h = 6
Parallelogram T:
b = 3 and h = 6
Step-by-step explanation:
The given information is incomplete and is not enough to answer the question. (See attachment for complete question)
Required
Determine the values of b and h for both parallelogram
The question will be answered by observing the features of each parallelogram and recording the required values
For parallelogram S.
The vertical arrow at the left-hand side represents b and the arrow highlights 7 grid boxes.
Hence:
[tex]b = 7[/tex]
The horizontal dotted lines represents h and this line highlights 6 grid boxes.
Hence:
[tex]h = 6[/tex]
For parallelogram T.
The horizontal arrow represents b and the arrow highlights 3 grid boxes.
Hence:
[tex]b = 3[/tex]
The vertical dotted lines represents h and this line highlights 6 grid boxes.
Hence:
[tex]h = 6[/tex]

Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
3(4x - 5) - 4x + 1 = -6
Step 2: Solve for x
Distribute 3: 12x - 15 - 4x + 1 = -6Combine like terms: 8x - 14 = -6Isolate x term: 8x = 8Isolate x: x = 1Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(4(1) - 5) - 4(1) + 1 = -6Multiply: 3(4 - 5) - 4 + 1 = -6Subtract: 3(-1) - 4 + 1 = -6Multiply: -3 - 4 + 1 = -6Subtract: -7 + 1 = -6Add: -6 = -6Here we see that -6 does indeed equal -6.
∴ x = 1 is the solution to the equation.
Carlos visita a sus abuelos cada 12 dias y su hermana sofia,cada8 dias.La ultima vez que conincidieron en la visita fue el dia 3 de enero ¿cuando volveran a coincidir? ¿cuantas veces habran visitado a sus abuelos cada uno entre los dos periodos que han coincidido?
Responder:
27 de enero
Horas de visita al abuelo antes de que coincida el horario = 1 vez
Horas de visita a Sofía antes de que coincida el horario = 2 veces
Explicación paso a paso:
Para obtener la hora en la que coincidirá su visita, obtenemos la L. C. M de 12 y 8
Abuelos (cada 12 días)
12:12, 24, 36, 48, 60, ...
Sofia (cada 8 días)
8: 8, 16, 24, 32, 40, ....
El mínimo común múltiplo de 12 y 8 es 24.
De ahí que su encuentro vuelva a coincidir a los 24 días.
3 de enero + 24 días = 27 de enero
Horas de visita al abuelo antes de que coincida el horario = 1 vez
Horas de visita a Sofía antes de que coincida el horario = 2 veces
