Answer:

5.2 feet.

Step-by-step explanation:

The useful equation to use for this problem is sine. Given the angle of measure 64 degrees, we have O (opposite) and H (hypotenuse).

From SOH CAH TOA, we see that we have O and H, so thus we should use sine.

Sine of any angle= opposite/hypotenuse.

Sine of 64= x/5.8

Sine of 64 (times 5.8)=x

x= 5.2 feet.

Additionally, you could use a right triangle calculator to solve for side x.

0.15(y-0.2)=2-0.5(1-y)<br><br> The answer is -153/35 I just need to know how to get that

butalik [34]

Answer:

$y=-\dfrac{153}{35}$ .

Step-by-step explanation:

The given equation is

$0.15(y-0.2)=2-0.5(1-y)$

Using distributive property, we get

$0.15(y)+0.15(-0.2)=2-0.5(1)-0.5(-y)$

$0.15y-0.03=2-0.5+0.5y$

$0.15y-0.03=1.5+0.5y$

Isolate variable terms.

$0.15y-0.5y=1.5+0.03$

$-0.35y=1.53$

Divide both sides by -0.35.

$y=\dfrac{1.53}{-0.35}$

$y=-\dfrac{1.53}{0.35}\times \dfrac{100}{100}$

$y=-\dfrac{153}{35}$

Therefore, $y=-\dfrac{153}{35}$ .

I just need the answers for questions 9 and 10

OverLord2011 [107]

Hello. To answer this questions, we need to remember some properties about fractions and equivalences.

Starting by the question 9:

Call the population 5 years ago by P. If the population has decreased 12000 in these 5 years and this represents a decrease of 3%, so it means the new population is 0.97P.

With this, we can make the following equation:

P - 12000 = 0.97P

Subtract 0.97P and sum 12000 in both sides of the equation

0.03P = 12000

Divide both sides of the equation by a factor of 0.03

P = 3600000
