There is `1/12 foot in one inch. Does the graph show the relationship between feet and inches?

KiRa [710]

Answer:

Yes

Step-by-step explanation:

Given that there is ¹/12 foot in 1 inch, this can be interpreted as being the constant of proportionality for the relationship between feet and inches. This means, for the graph to be said to represent this relationship, the constant of proportionality, which is y/x must be ¹/12.

How do we know this? Check this out using the four points given on the graph.

(12, 1) => y/x = ¹/12

(24, 2) => y/x = ²/24 = ¹/12

(36, 3) => y/x = ³/36 = ¹/12

(48, 4) => y/x = ⁴/48 = ¹/12

As we can see, the graph represents the shows a relationship between feet and inches.

Basile [38]

Answer:

A. h=3v/b

Step-by-step explanation:

v=1/3bh

1) divide by b

v/b=1/3h

2) multiply reciprical

What is the difference between multiplying a whole number by a decimal and multiplying two whole numbers

anastassius [24]

Two whole numbers will end up like this: 8x8=64,but multiplying a whole and a decimal will end up like this 8x8.1=64.1
or 8x8=8 to the second power.

118 cars were sold during the month of April. 68 had air conditioning and 61 had automatic transmission. 44 had air conditioning

Dmitry_Shevchenko [17]

Answer:

88.98% probability that a randomly selected car had automatic transmission or air conditioning or both

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

37 had automatic transmission only

44 had air conditioning only

61 had automatic transmission

This already counts those with both automatic transmission and air conditioning. So 61-37 = 24 had both.

So $D = 37 + 44 + 24 = 105$

Total outcomes:

118 cars sold, so $T = 118$ .

What is the probability that a randomly selected car had automatic transmission or air conditioning or both?

$p = \frac{D}{T} = \frac{105}{118} = 0.8898$

88.98% probability that a randomly selected car had automatic transmission or air conditioning or both
