4. The hypotenuse of a 30°- 60°- 90° right triangle measures 22 cm. What are the lengths of the longer leg and shorter leg? 4. T
s2008m [1.1K]
We are given the a right triangle and the interior angles of the triangle. We use some trigonometric functions to solve the length of the remaining legs. We calculate as follows:

let a and b the length of the legs

cos 30 = a / 22
         a = 19.05 cm

sin 30 = b / 22
        b = 11 cm

Hope this answers the question. Have a nice day.

Solve the following system of linear equations.
andrey2020 [161]
To solve a problem like this, you will need to use substitution or elimination. For the sake of an example I will solve this using substitution.

First, solve one of the equations for x or y:
3x-5y=-39
3x=-39+5y
X=(-39+5y)/3

Then substitute for the value of x in the second equation:
6x+2y=-42
6((-39+5y)/3)+2y=-42

Solve for y:
-78+10y +2y=-42
-78+12y=-42
12y=36
Y=3

Once you've solved for y, you can plug in it's value to find x:
X=-39+5(3)/3
X=-24/3
X=-8

So, we can conclude that the correct answer is B. (-8,3)

If the interest rate on a savings account is 0.02%, approximately how much money do you need to keep in this account for 1 year
astraxan [27]
At first glance, this problem might be overwhelming so try approaching it slowly by doing these steps:

Step 1: Start by understanding what the problem is really asking.
You might notice that the problem is just a percentage problem, with a twist! If you still don't see it, the problem is just asking what the base should be given a percentage and the amount.

Step 2: Recall the concepts relevant to the question.
We can identify a single formula that will be important in getting the answer:
base*percent=amount

Step 3: Apply the concept to the context of the problem.
You'll see that we already have the percent from the interest rate which is 0.02% and the amount from the below-minimum-balance fee which is $9.99.

There goes the little twist: you have to manipulate the equation to get the base. Dividing both sides of the equation by the percent we'll have:
base= \frac{amount}{percent}

Step 4: Evaluate to get the answer to the problem.
We simply substitute the given numbers and evaluate.
base= \frac{percent}{amount}= \frac{9.99}{0.0002} =49,950

Answer: You need $49,950 in the account to cover the Below-Minimum-Balance Fee from your interest.

Addison is making caramel apples. She has 2 1/2 bags of apples. One full bag has 8 apples, and each apple weighs 5 oz. Write an
Lina20 [59]

Answer:

She has 100 ounces.

Step-by-step explanation:

Since one bag has 8 apples, two of the bags have 8 apples and the one half bag of apples has 4 apples.

  • Add 8+8+4=20

Then, since each apple weighs 5 ounces you multiply:

  • 1 Apple = 5 ounces
  • 20 * 5 = 100

Equation:

= 2 1/2 × 8

= 5/2 × 8

= 40/2

= 20

20 x 5 = 100
