12m, and 8m what is the third angle of the tirangle

1 answer:

8 0

So we use pythagorean theorem.

a^2+b^2=c^2

Do you have the triangle drawn ? It matters what side we are solving for.

12m^2 + 8m^2 = c^2

c^2= 208

c= 14.42 m

I can solve for what you want, just need some information from you

Answer:

$t=5$ dollars per t-shirt

Step-by-step explanation:

<em>Read the problem and write your equation while following along with it</em>

We have 8 t-shirts

Lets 8 t-shirts be represented by 8t

So for our equation we will place and $8$

<h3>Our equation: $8t$ </h3><h3 />

Now it says we have a coupon that subtracts 4 dollars from our total

<h3>Our equation: $8t-4$ </h3><h3 />

The final part to add to our equation says that our total before tax was 36 dollars

<h3>So here is our equation: $8t-4=36$ </h3><h3 />

<em>add </em> $$$ $4$ <em> to both sides</em>

$8t=40$

<em>Divide both sides by</em> $8$

$t=5$ dollars per t-shirt

-Side note, make sure to spell your question right. It was a tad bit confusing to read at the start.

Answer:

SOLUTION STEPS

+−6

Multiply 6 and 8 to get 48.

48+5

−

6×3+1

Add 48 and 5 to get 53.

−

6×3+1

Multiply 6 and 3 to get 18.

−

18+1

Add 18 and 1 to get 19.

−

Least common multiple of 8 and 3 is 24. Convert

and

to fractions with denominator 24.

159

−

152

Since

159

and

152

have the same denominator, subtract them by subtracting their numerators.

159−152

Subtract 152 from 159 to get 7.

What is the value of x in the diagram below?

dusya [7]

we know that

the two triangles in the figure are similar, because they have three equal angles

therefore

The ratio of the corresponding sides are equal

$\frac{x}{8}= \frac{18}{48} \\ \\x=(8*18)/48 \\ \\x=3\ units$

therefore

<u>the answer is the option C</u>

$3$

2. Ariana has created a paper airplane for her physics class at school where all the students will be testing their planes by se

sergiy2304 [10]

Answer:

2. The airplane will crash into the ground after 5 seconds.

3. The domain of the function is [0,30] and range of the function is $[-\infty,900]$ .

Step-by-step explanation:

Ariana initial attempt is modeled by the function,

$h(x)=x^2-12x+35$

where, h is the height in feet and x is the time in seconds of the paper airplanes path.

If airplane crash into the ground, then $h(x)=0$ ,

$0=x^2-12x+35$

$0=x^2-7x-5x+35$

$0=x(x-7)-5(x-7)$

$0=(x-7)(x-5)$

Equate each factor equal to 0.

$x=5,7$

Therefore the airplane will crash into the ground after 5 seconds.

The height of the rocket in meters is modeled by the function shown below, where t is time in seconds.

$h(t)=-4t^2+120t$

The value of t must be positive because time can not be negative.

Find the zeros of the function.

$0=-4t(t-30)$

$t=0,30$

The leading coefficient is negative, so the it is a downward parabola. Since the zeros of the function are 0 and 30, therefore the function is negative before 0 and after 30.

The height can not be negative, so the domain of the function is

$0\leq t\leq 30$
