Answer:

33 material

Step-by-step explanation:

A simple proportions problem.

9:3 = 3:1

so it takes 3 yards to make 1 window

We multiply both sides by 11 to get

33:11 which now we get 33 material

Answer the question to become the brainliest

olya-2409 [2.1K]

Answer:

a) The distance travelled on the cycle in the first 14 seconds is 96 meters.

b) The acceleration in the first 4 seconds is 2 meters per square second.

Step-by-step explanation:

a) The distance travelled by the cycle is equal to the area below the curve, which is the sum of the first triangle and the rectangle:

$\Delta x = \frac{1}{2}\cdot \left(8\,\frac{m}{s} \right) \cdot (4\,s-0\,s)+\left(8\,\frac{m}{s}\right)\cdot (14\,s-4\,s)$

$\Delta x = 16\,m +80\,m$

$\Delta x = 96\,m$

The distance travelled on the cycle in the first 14 seconds is 96 meters.

b) The acceleration is represented by the slope of the line, which is determined by definition of secant line:

$a = \frac{v(4\,s)-v(0\,s)}{4\,s-0\,s}$ (1)

$a = \frac{8\,\frac{m}{s}-0\,\frac{m}{s}}{4\,s-0\,s}$

$a =2\,\frac{m}{s^{2}}$

The acceleration in the first 4 seconds is 2 meters per square second.

Who s the first person to eat food?

Blizzard [7]

This is impossible to answer. This all depends on what you define as a 'person.' If you are talking about the first Homo Sapiens, then that would be around 2 million years ago, but the predecessors of Homo sapiens could also be considered 'people,' so then you'd have to determine at what point they came into existence.

Which is the best description of the graph of the function f(x) = 60(One-third)x? The graph has an initial value of 20, and each

dezoksy [38]

Answer:

The graph has an initial value of 60, and each successive term is determined by multiplying by One-third.

Step-by-step explanation:

Which is the best description of the graph of the function f(x) = 60(One-third)x?

A. The graph has an initial value of 20, and each successive term is determined by subtracting One-third.

B. The graph has an initial value of 20, and each successive term is determined by multiplying by One-third.

C. The graph has an initial value of 60, and each successive term is determined by subtracting One-third.

D. The graph has an initial value of 60, and each successive term is determined by multiplying by One-third.

Given:

f(x) = 60 (1/3)^x see graph attached.

Examining the graph, we notice that

1. The graph has an initial value of 60, at point (0,60)

2. The graph decreases as x increases. Each successive term is determined by multiplying by 1/3, namely in the sequence

{(0,60), (1,20), (2, 20/3), (3, 20/9), ...}

This means the choice is D (or the fourth one).
