A polygon has an angle sum of 360°, and each angle measures 90°. What is the polygon?

Answers

Answer 1

Answer: A polygon has an angle sum of 360°, and each angle measures 90°. Let's find our what is the polygon.
=> 360 degrees polygon with 90 degree measure for each angles.
=> 360 degrees / 90 degrees = 4
Therefore the polygon is a square.

the areas of the two watch faces have a ratio of 16:25. what is the ratio of the radius of the smaller watch face to the radius of the larger watch face?

Answers

The ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.

What is the area of the circle?

The area of the circle is given by the formula,

$\text{Area of the Circle} = \pi r^2$

As we know that the ratio of the area of the two watches is 16:25. And we also know that the area of a circle is given by the formula,

$\text{Area of the Circle} = \pi r^2$

Now, as we know that the ratio of the area of the watches can be written as,

$\frac{\text{Area of the small watch face}}{\text{Area of the Large watch face}} = (16)/(25)\n\n(\pi r^2)/(\pi R^2) =(16)/(25)\n\n(r^2)/(R^2) = (16)/(25)\n\n(r)/(R) = \sqrt{(16)/(25)}\n(r)/(R) = (4)/(5)$

Hence, the ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.

Answer:

4:5

Step-by-step explanation:

Let r be the radius of small watch

Area of small watch=π $r^(2)$

Let R be radius of larger watch= π $R^(2)$

Area of larger watch= π $R^(2)$

It is given that the ratio of their areas= 16:25

$( Area of smaller circe)/(Area of larger circle)$ = $(16)/(25)$

π $r^(2)$ : π $R^(2)$ = 16:25

$(r)/(R)$ = $(√(16) )/(√(25) )$

r:R= 4:5

Hence, the ratio of their radii= 4:5

Hence, the correct answer is 4:5

Homer Simpson weighs 400 pounds. He is on a diet to lose 5 pounds each week Barney weighs 322 pounds. he is on a diet to lose 3 pounds each week. How long will it take for them to weigh the same? write an equation and solve.

Answers

400 + (n-1) (-5) = 322 + (n-1) (-3)
-5n + 5 = 322
-3n + 3 | 405 - 5n
=325 - 3n
80=2n
n=40 n - 1 = 39

Answer = 39 , 39 weeks until they weigh the same
