Step-by-step explanation:

1 m = 3.280839895... ft

therefore,

1 m² = 10.76391042... ft²

35 m² = 35 × 10.76391042... ft² =

= 376.7368646... ft²

the area of the circle is

pi×r²

r = 50/2 = 25 ft

so, the area of the red circle is

pi×25² = pi×625 = 1,963.495408... ft²

we need to paint it twice, so the area to be painted is twice the area of the circle

2×pi×625 = 3,926.990817... ft²

we need a many cans as the cover area of a single can fits into the total area to be painted :

3,926.990817... / 376.7368646... = 10.42369671... cans

we need to round this up to full cans.

so, we need 11 cans of red paint to give that red pad 2 coats of paint.

SAT question <br> Can someone explain to me what this is asking

frozen [14]

Answer:

Step-by-step explanation:

The vertex is the turning point of the parabola.

First find the zeros by equating y to zero, that is

(x - 6)(x + 12) = 0

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 12 = 0 ⇒ x = - 12

The vertex lies on the axis of symmetry which is situated at the midpoint of the zeros, thus

$x_{vertex}$ = $\frac{6-12}{2}$ = $\frac{-6}{2}$ = - 3

Thus the x- coordinate of the vertex is x = - 3 → B

A sequence is defined by

garik1379 [7]

I believe the answer is D.

3^2 is 9 and 4^2 is 16, and because 9/16 was the third term in the sequence, you raise both the numerator and the denominator by the number of the term minus 1.

So to find the seventh term, you raise the numerator and denominator by 7 - 1 = 6.

So the answer is 729/4096
