Someone please solve for z

Answers

Answer:

z = 52

Step-by-step explanation:

x + 38 = 90 because it is a complementary angle.

So, we just need to subtract 38 from 90:

90 - 38 = x

90 - 38 = 52

What is 3m + 4n - 6n

Answers

Simple,

3m+4n-6n

Simplify your variables....

4n-6n= -2n

Thus,

3m-2n.

That's it, it's simplified...done...out of here...

Thus, your answer is, 3m-2n.

Simplify

3m+4n-6n

= 3m+4n+-6n

Combine like terms

3m+4n+-6n

(3m)+(4n+-6n)

(3m)+(4n-6n)

= 3m -2n

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

How do you get the answer for 10 millimeters increased by 30%

Answers

First you have to find what 30% of ten is, and then add it to the 10. So how do you find 30 % of 10? In math...

"of" means ×
"is" means =

30% of 10 is
30 % × 10 =

change 30% to a decimal by dividing by 100 ( move the decimal to the left 2 places)

.30 × 10 = 3

So 30% of ten is 3. Now since we are increasing by 30%, we have to add it to the original value, 10.

3 + 10 = 13

So 10 millimeters increased by 30% is

13 millimeters
