Answer:
440 Rock CDs
Step-by-step explanation:
Let number of rock CDs be "r", and
number of Jazz CDs be "j"
4 times as many Rock as Jazz, so we can write:
r = 4j
Total of 550 CDs, thus we can write equation 2:
r + j = 550
Now we replace 2nd equation with 1st equation and find j first:
r + j = 550
4j + j = 550
5j = 550
j = 550/5
j = 110
Now, finding r:
r = 4j
r = 4(110)
r = 440
There are 110 Jazz CDs and 440 Rock CDs
Answer:
1 and 68.
Step-by-step explanation: 1 - 68 = 67.
Answer:
12 feet
Step-by-step explanation:
Given in the question,
horizontal distance from sister to rock wall = 5.5 feet
diagonal distance from sister to rock wall's peak = 13.42 feet
<h3>
To find the height </h3>
As we know this figure make a right angle triangle, so we will apply pythagorus theorem
hypotenuse² = height² + base²
13.42² = height² + 5.5²
13.42² - 5.5² = height²
149.85 = height²
height = √149.85
height = 12.24 feet
Approximate height of her rock wall to the nearest tenth = 12 feet
In the triangle LJK, the length of side LK=18.
In the triangle L'J'K', the length of side L'K'=6
Therefore,
Therefore, the scale factor for dilation is 1/3.
So, the dilation can be represented as
So, Emily's statement is correct.
