SOH CAH TOA tells you the sine function of an angle gives the ratio of opposite side to the hypotenuse of the right triangle.
Sin = Opposite/Hypotenuse
In this problem, the angle is 15°, the hypotenuse is 3000 m and we want to find the length of the opposite side (the height above the ground).

sin(30°) = height/(3000 m)
Multiplying by 3000 m, we get
height = (3000 m)*sin(30°) = 1500 m

The height of the plane at that instant is ...
1500 m

### What is a fraction?

Fractions represent the parts of a whole or collection of objects.

A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.

Now it is given that,

Pounds of glass recycled = 7 2/3

⇒ Pounds of glass recycled = 23/3

Pounds of paper recycled = 9 3/4

⇒ Pounds of paper recycled = 39/4

Thus, total pounds of glass and paper recycled = Pounds of glass recycled + Pounds of paper recycled

total pounds of glass and paper recycled = 23/3 + 39/4

total pounds of glass and paper recycled = 209/12

total pounds of glass and paper recycled = 17 5/12 pounds

Thus, the students recycle 17 5/12 pounds of glass and paper all together.

Question
n May, Bradley bought 48 Styrofoam balls and decorated them as toy figurines. In June, he sold 19 figurines. In May, Lupe bought 44 Styrofoam balls to decorate, and in June, she sold 21 figurines. Which matrix represents all of their May purchases and their June sales?
Solution 1 Step-by-step explanation:

Since we have given that

Number of Styrofoam balls bought by Bradley in May = 48

Number of figurines sold by Bradley in June = 19

Number of Styrofoam balls bought by Lupe in May = 44

Number of figurines sold by Lupe in June = 21

So, it will be written as

Purchases      Sales

May                            48               19

June                          44               21

So, the matrix would be Solution 2
48 19
44 21. this is what it should look like
Question
Yanis fires pottery in a kiln. He decides to measure the rate of change of temperature of the pottery over time. What would be an appropriate unit for Yanis's purpose?
Solution 1

Pottery is on a Kiln.

Unit of temperature can be Kelvin(°K) or Degree Celsius(°C) or Fahrenheit(°F).

Unit of time is second, minute and hour.

Rate of change of temperature of the pottery over time can be written as Internationally , Kelvin is used as S.I unit of Temperature.

So,Yanin can use as Rate of change of temperature of the pottery over time.

Solution 2
Degrees celcius/ hour

### What is a prime number?

"A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers."

The given factored forms are:

A. 2 x 2 x 2 x 3

Here, all the numbers are prime numbers.

Therefore, this factored form is the prime factored form.

B. 2 x 4 x 2 x 3

Here, all the numbers are not prime numbers.

Therefore, this factored form is not the prime factored form.

C. 8 x 6

Here, not a single number is prime number.

Therefore, this factored form is not the prime factored form.

D. 2 x 12

Here, all the numbers are not prime numbers.

Therefore, this factored form is not the prime factored form.
