Step-by-step explanation:
For all problems, the ratios of the lengths of the sides are:
30-60-90 triangle 1 : √3 : 2
45-45-90 triangle 1 : √2 : √2
Problem 3:
30-60-90 triangle at left
Hypotenuse = 11
Short leg = 11/2
Long leg = 11/2 × √3
45-45-90 triangle at right
x = 11/2 × √3 × √2 = 11√6/2
Answer: D
Problem 4:
30-60-90 triangle at top
Hypotenuse = 7√3
Short leg = 7√3/2
Long leg = 7√3/2 × √3 = 7 × 3/2 = 21/2
45-45-90 triangle at right
x = 21/2 × √2 = 21√2/2
Answer: 21√2/2
Problem 7:
30-60-90 triangle
Long leg = 4√3
Short leg = y = 4√2/2 = 2√2
Answer: C.
Problem 6:
30-60-90 triangle at left
Hypotenuse = 12√6
Short leg = 12√6/2 = 6√6
Long leg = 6√6 × √3 = 6√2√3√3 = 18√2
45-45-90 triangle at right
x = 18√2/√2 = 18
Answer: C.
Problem 8:
45-45-90 triangle
Hypotenuse = 2
Leg = y = 2/√2 = 2√2/(√2√2) = √2
Answer: C.
Answer:
<u>54 cups</u> of rice are needed to feed 135 people.
Step-by-step explanation:
Given:
Balvina knows that 6 cups of rice will make enough spanish rice to feed 15 people.
Now, to find the cups of rice needed to feed 135 people.
Let the cups of rice needed to feed 135 people be 
As, 6 cups of rice is needed to feed 15 people.
<em>So, 6 is equivalent to 15.</em>
<em>Thus, </em>
<em> is equivalent to 135.</em>
Now, to get the cups of rice needed to feed 135 people we use cross multiplication method:
<em>By cross multiplying we get:</em>
<em />
<em />
<em>Dividing both sides by 15 we get:</em>
Therefore, 54 cups of rice are needed to feed 135 people.
