Answer:

Step-by-step explanation:

A = 4πr² = 4π9² = 324π units²

324(3.14) = 1,017.36 units²

AYUDA PLIS 1) Pablo compro un sobre de jugo que les costo $28,85, un alfajor por $85,50 y un helado. Si pago con $250 ¿Cuánto co

astraxan [27]

Answer:

1) El helado costó $135,65.

2) a) Gastó en total $487,5. b) Le dieron $112,5 de vuleto.

Step-by-step explanation:

1) Podemos encontrar el costo del helado como sigue:

$T = J + A + H$

$H = T - J - A = 250 - 28,85 - 85,50 = 135,65$

Por lo tanto, el helado costó $135,65.

2) a) Para saber cuanto dinero gastó debemos sumar todos los precios:

$T = B_{p} + B_{g} + P = 349,50 + 108,25 + 29,75 = 487,5$

Entonces, gastó en total $487,5.

b) Si pagó con $600, su vuelto fue:

$V = 600 - T = 600 - 487,5 = 112,5$

Le dieron $112,5 de vuleto.

Find the derivative of 76x + 1 at x = 1.

Murljashka [212]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

$\qquad \sf \dashrightarrow \: \dfrac{d}{dx}(76x + 1)$

$\qquad \sf \dashrightarrow \:76 {x}^{1 - 1} + 0$

$\qquad \sf \dashrightarrow \:76 {x}^{0} + 0$

$\qquad \sf \dashrightarrow \:76$

Here, we have got a constant number, therefore for any value of x it will be 76

Therefore, derivative of 76x + 1 at x = 1 is 76

A 50 loot ladder is leaning against a building. If the base of the ladder is 35 feet from the base of the building, how far up t

Hatshy [7]

Answer:

The ladder is 35.71 feet up the building

Step-by-step explanation:

Here, we want to calculate how far up the building is the ladder placed

We should picture a right angled triangle with hypotenuse 50 and one of the other sides as 35

To find the height in this case, we proceed to use Pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the squares of the two other sides

In this case, let the height be

50^2 = 35^2 + h^2

h^2 = 50^2-35^2

h^2 = (50+35)(50-35)

h^2 = (85)(15)

h^2 = 1275

h = square root of 1275

h = 35.71 ft

Which of the following is not represented by the image below

love history [14]

Answer:

Line BD can't be represent by the image.

Explanation:

Point: Point is a dot or vertex of any figure or diagram. It represent by capital alphabet. So, B would be a point.

Line: A line is a straight path with both endless. It means we can extends line from both end. But in case of BD we can't extend from point B. So, it won't be line.

Ray: A ray is straight path with one endless. It means we can't extend line from one end and extend from another end. But we can extend AC from both end. It won't be a ray.

Line Segment: A line segement is straight path with end from both end. We can't extend from either end of the line. We can say CD would be line segment.

Option 2 is correct.
