Which of the following ratio is equivalent to 3/16? a. 16:3

2 answers:

8 0

The answer is A because in order to convert a fraction to a ratio, you first write down the numerator which in this case is 3. Then you write a colon to separate the 2 numbers and write down the denominator which is 16. So in the ratio would be 3:16 or 16:3. In some cases, you may have to simplify the ratio, but in this case, it cannot be simplified any further, so A is the right answer

If one ratio is equivalent to another, that means that you multiply the top and the bottom on one ratio by a constant to get the larger ratio. D does that here for us. We have to multiply 3 by 5 to get to 15, so 16 times 5 better be 80 and it is.

The heights (in cm) and arm spans (in cm) of 31 students were measured. The association between x(height) and y(arm span) is sho

abruzzese [7]

Answer:

27.385 cm longer would we expect Mike's arm span to be than George's.

Step-by-step explanation:

We have to find how many centimeters longer would we expect Mike's arm span to be than George's using the equation:

y= 4.5x + 0.977 x

where y= arm span

and x= height

Given:

Mike's height=x = 175 cm

so Mike's arm span= y= 4.5 x + 0.977 x

= 4.5* (175) + 0.977* (175)

= 787.5 + 170.975

= 958.475 cm

George's height = x = 170 cm

so George's arm span= y= 4.5 x + 0.977 x

= 4.5* (170) + 0.977* (170)

= 765 + 166.09

= 931.09 cm

Mike's arm span longer than George's = Mike's arm span - George's arm span

= 958.475 - 931.09

= 27.385 cm.

Determine if the graph is symmetric about the x-axis, the y-axis, or the origin.

gulaghasi [49]

This equation is an example of a Limacon with inner loop. By using the symmetry tests where:

POLAR AXIS/HORIZONTAL:
replace a) θ by -θ, b) r by -r and θ by π-θ

VERTICAL AXIS:
replace a) θ by π-θ, b) r by -r and θ by -θ

POLE:
replace a) θ by π+θ, b) r by -r

If any of these rules, after replacing it in the equation, results to the original equation (making it the equivalent) then it is symmetrical to that axis.

In this case, it is only symmetrical about the polar/horizontal axis.
