What is a square plus b square equal c square

Answer:

B

Step-by-step explanation:

Answer:

Let R = radius of big circle

r=radius of small circle

A1=Area of small circle

A2=Area of big circle

R=9r

A1=50cm^2

A1=pi*r*2

A2=pi*R^2

A2=pi*(9r)^2

A2=81*pi*r^2

A2=81*A1

A2=4050cm^2

Hence the big circle has area of 4050cm^2

Step-by-step explanation:

The answer is 4050 cm²

The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.

Given here: The radius of a circle is 9 times the radius of a smaller circle.  And area of the smaller circle is 50 cm² then let the area of the larger circle be x

π9²/π1² =x/50

 x=4050

Hence, The answer is 4050 cm²

Answer:

x = 25

Step-by-step explanation:

4x +50 = 150

4x = 150-50

4x = 100

4x/4 = 100/4

x = 25

Answer:

x=25

Step-by-step explanation:

Vertical angles are always congruent.

Answer:

y = - 2x + 12

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

4x + 2y = 24 ( subtract 4x from both sides )

2y = - 4x + 24 ( divide all terms by 2 )

y = - 2x + 12 ← in slope- intercept form

Answer:

x<7/12

Step-by-step explanation:

you have to get X by its self so you take the 1/4 and subtract it from both sides

Step-by-step explanation:

Answer:

y=5/4x-11

Step-by-step explanation:

tenemos un punto (4,-6) y una pendiente equal a 5/4.

usa la ecuación y=mx+b (m es la pendiente, b es el y interceptar)

porque sabemos la pendiente es 5/4, ahora mismo la ecuación es:

y=5/4x+b

en el punto, x=4, y=-6

podemos sustituir los números en la fómula para resolver b

-6=4(5/4)+b

-6=5+b

-11=b

entonces,

la ecuación de la recta es y=5/4x-11

Answer:

A) f(x) = 1/3x

Step-by-step explanation:

You can rule out B and C-

B is a quadratic function, seeing as how x is being squared, and C is an absolute value function. Neither of these are linear so you don't have to worry about it here.

That leaves us with A and D, which are both linear.

Linear functions usually take the form of f(x) = mx + b. In a proportional linear function, b = 0.

So with that in mind, you should see that the b value for f(x) = 2x + 11 is 11, which should rule D out as well.

That leaves you with f(x) = 1/3x. As you can see, there's no b value in this function, which means b = 0 and the function is proportional.

Hope this helped :D

Answer: 262.6

Step-by-step explanation: Well if she sold 110 hamburgers on tuesday for $545 That is a simple division equation (545/110). After dividing the answer would be how much each hamburguer cost on its own ( 4.954545454545455), you would then multiply that by the number of hamburgers she sold (53) and get your answer. (262.5909090909091) I am not quite sure where she wants us to round the answer to. so I just did the tens place.
