Snezhnost [94]3 years ago

Answer:

24.12

Step-by-step explanation:

Looking from the angle of 56 degrees, you see that the side with 20 degrees is opposite, and x is the hypotenuse.

The trig function that uses both opposite and hypotenuse is sin.

Therefore in order to solve this, you must first set up a trig function:

sin(56)=20/X

In order to solve the equation above you need to multiply sin(56) by x and divide 20 by sin(56).

This gives you the answer of 24.12

The ratio of bows to headbands of Monique's hair accessories is 8:4. Select all true statements.
Nadya [2.5K]

The ratio of bows to headbands is 8:4. This means that for every 8 bows, there are 4 headbands, Then, a true statement is the second option.

Since there are 8 bows + 4headbands = 12 accessories, this also implies that for every 12 hair accesories, there are 4 headbands. This solution corresponds to the last option.

Hence, the true statements are the second and last options.

Multiply. {}=3\dfrac{1}{2} \times 3\dfrac12=3 2 1 ​ ×3 2 1 ​
Inessa [10]

I assume you mean the product of mixed numbers,

3 1/2 × 3 1/2

If we write this as

(3 + 1/2) × (3 + 1/2) = (3 + 1/2)²

we can use the identity

(a + b)² = a² + 2ab + b²

so that

3 1/2 × 3 1/2 = 3² + (2 × 3 × 1/2) + (1/2)²

3 1/2 × 3 1/2 = 9 + 3 + 1/4

3 1/2 × 3 1/2 = 12 1/4

Alternatively, we can first write 3 1/2 as a mixed number:

3 + 1/2 = 6/2 + 1/2 = (6 + 1)/2 = 7/2

Then

3 1/2 × 3 1/2 = 7/2 × 7/2 = (7 × 7) / (2 × 2) = 49/4

and

49/4 = (48 + 1)/4 = ((4 × 12) + 1)/4 = 12 + 1/4
