Answer:

$174.66\ mi$ or $175\ mi$

Step-by-step explanation:

we know that

Applying the law of cosines

$c^{2}=a^{2}+b^{2}-2(a)(b)cos(C)$

In this problem we have

$a=200\ mi$

$b=30\ mi$

$C=30\°$

substitute the values

$c^{2}=200^{2}+30^{2}-2(200)(30)cos(30\°)$

$c^{2}=30,507.695$

$c=174.66\ mi$

Solve -14-5y >-64<br> A. Y<10<br> B.y>-10<br> C. Y>10<br> D.y<-10

Hello :D

Answer:

A. $Y$

Step-by-step explanation:

First, you add by 14 both sides of an equation.

-14-5y+14>-64+14

Then, simplify by equation.

-64+14=-50

-5y>-50

Multiply -1 both sides.

(-5y)(-1)<(-50)(-1)

5y<50

Divide by 5 both sides of an equation.

5y/5<50/5

Divide numbers from left to right.

50/5=10

y<10 is the correct answer.

Hope this helps you! :D

-1/2 + ( 3/4 x 4/9)

SIZIF [17.4K]

Answer:

-1/6

Step-by-step explanation:

-1/2 + ( 3/4 x 4/9)

PEMDAS says parentheses first

Rearranging the fractions

-1/2 + ( 3/9 x 4/4)

-1/2 + (1/3*1)

-1/2 + 1/3

Getting a common denominator of 6

-1/2 *3/3 + 1/3 *2/2

-3/6+2/6

-1/6
