Simplify each of the following ratios.<br>e) 2/3 : 3/2 : 5/8​
Snezhnost [94]

Answer:

32/45

Step-by-step explanation:

2/3 : 3/2 : 5/8

Remember, a ratio and a fraction are both division. Therefore you can rewrite the problem like so:

2/3 ÷ 3/2 ÷ 5/8

Dividing fractions is the same as multiplying them by the reciprocal.

2/3 * 2/3 * 8/5

Now simplify:

32/45

32 and 45 have no common factor, hence the final answer is 32/45

In triangle ABC, cos A =
nikitadnepr [17]

The other expression that has a value of \frac{7}{25} is A) sin B.

Step-by-step explanation:

Step 1:

sin\theta = \frac{oppositeside}{hypotenuse} , cos\theta = \frac{adjacentside}{hypotenuse} , tan \theta = \frac{opposite side}{adjacent side} .

For angle B, the opposite side measures 7 units, the adjacent side measures 24 units and the hypotenuse measures 25 units.

sinB= \frac{oppositeside}{hypotenuse} = \frac{7}{25} , tan B = \frac{opposite side}{adjacent side}  = \frac{7}{24} , cosB = \frac{adjacentside}{hypotenuse}  = \frac{24}{25}.

Step 2:

For angle A, the opposite side measures 24 units, the adjacent side measures 7 units and the hypotenuse measures 25 units.

tan A = \frac{opposite side}{adjacent side}  = \frac{24}{25} .

Step 3:

tan C cannot be determined as C is the right angle. The opposite side and hypotenuse of the triangle would be the same.

So sin B also has a value of \frac{7}{25}. This is option A.
