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.

hat is the slope-intercept form of the linear equation 4x + 2y = 24?

Answers

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

Una recta atraviesa el punto (4,-6) Y tiene una pendiente igual a 5/4

Ayúdenme con este problemaaa porfavor

Answers

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

The radius of a circle is 9 times the radius of a smaller circle. The area of the smaller circle is 50 square centimeters. What is the area of the larger circle?

Answers

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

What is the area and circumference of a circle?

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
