Answer:

5.6

Step-by-step explanation:

Use pythag to get SU. 10^2 + x^2 = 15^2, this will give you x = 11.2. 11.2 is the diameter of SU so divide it by 2 to get the radius. 11.2/2= 5.6.

Answer:

Answer is 6.12

Step-by-step explanation:

pythagoras Theorem according to

$\sqrt{AB^{2}-BD^{2}} = \sqrt{AD}$

NOW WE FOUND AD,

SO, $\sqrt{AD^{2}+CD^{2} }} = \sqrt{AC^{2} } = 6.12$ YOU WILL FOUND THE SOLUTION WHEN YOU ENTER THE Value

If the circumference of a circle is 120 inches and M angle B equals 18° then what is the length of arc AC

Andru [333]

Answer:

For a circle of radius R, the circumference is:

C = 2*pi*R

where pi = 3.14

And if we have an arc defined by an angle θ, the length of the arc is:

A = (θ/360°)*2*pi*R

Here we can not see the image, then i assume that B is the angle that defines the arc AC.

Now we know that the circumference is 120 in, then:

2*pi*R = 120in

Then the length of the arc is:

A = (θ/360°)*120 in

Then if the angle is 18°, we have:

A = (18°/360)*120 in = 6in

Which expressionis equal to (-7x+5.1y)-(-9x+5.3y)

Furkat [3]

Answer:

The simplified expression for the given expression will be:

c. $2x-0.2y$

Step-by-step explanation:

Given expression:

$(-7x+5.1y)-(-9x+5.3y)$

To simplify the expression.

Solution:

In order to simplify the expression, we will first remove the parenthesis by reversing the signs of the terms inside the parenthesis which lies after a negative sign out side the parenthesis.

This is because negative multiplies to a negative to give a positive and negative multiplies to a positive to give a negative.

So, we have:

⇒ $-7x+5.1y+9x-5.3y$

Combining like terms

⇒ $-7x+9x+5.1y-5.3y$

The like terms can be evaluated as

$-7x+9x=2x$

$5.1y-5.3y=-0.2y$

Thus, the simplified expression will be:

⇒ $2x-0.2y$
