Answer: Second Option is correct.

Step-by-step explanation:

Since we have given that

Quadrant with radius 16 inches and angle 90° .

$\text{Length of an arc of quadrant}=\frac{\theta}{360\textdegree}2\times \pi \times r\\\\\text{Length of an arc of quadrant}=\frac{1}{4}\times 2\times 3.14\times 16\\\\\text{Length of an arc of quadrant}=25.12$

Since there are two quadrants:

So, Perimeter of quadrants is given by

$25.12\times 2\\\\50.24\ in.$

Perimeter of this figure is given by

$50.24+16+16+16+16\\\\=114.24\ in$

Hence, Second Option is correct.

Which inequality represents "six times a number is less than negative thirty-nine and three-quarters"?

jarptica [38.1K]

Answer:

6*n < - (39 + 3/4)

Step-by-step explanation:

Let's do it in steps:

"Six times a number" can be written as:

6*n

Where n is the "number"

"... is less than negative thirty-nine and three-quarters "

then we have:

6*n < - (39 + 3/4)

This is the inequality we wanted, now we can also solve this for n as:

n < -(39 + 3/4)/6

Answer:

$4ft *\frac{12in}{1 ft}= 48 in$

Now since we have the same units for the scale model and the real one we can find the scale factor like this:

$Scale = \frac{48 in}{6in}= 8$

And we can conclude that the scale factor is 1:8 and that represent that the real object is 8 times larger than the scale model

Step-by-step explanation:

For this problem we know that the scale model had a widthof 6 inches. And the actual model has a width of 4ft. First we need to convert the 4ft to inches and we got:

$4ft *\frac{12in}{1 ft}= 48 in$

Now since we have the same units for the scale model and the real one we can find the scale factor like this:

$Scale = \frac{48 in}{6in}= 8$

And we can conclude that the scale factor is 1:8 and that represent that the real object is 8 times larger than the scale model
