Answer:
D
Step-by-step explanation:
r = 5 units

3.305
+1.7
5.005
Line up the decimal points and add like you usually would add.
5.005 is the answer.
Take that certain number we are looking for as 'n'
38% ⇒ 0.38
0.38n = 152
Divide by 0.38
0.38n = 152
/0.38 /0.38
n = 400
So 38% of 400 is 152.
1. First, you must find the constant of variation (k). The problem indicates that t<span>he base of each triangle varies inversely with the height. So, this can be represented as below:
</span>
B=k/H
B is the base of the triangle (B=10).
H is the height of the triangle (H=6).
k is the constant of variation.
2. When you clear "k", you obtain:
B=k/H
k=BxH
k=10x6
k=60
3. Now, you have:
B=60/H
4. You can give any value to "H" and you will obtain the base of the second triangle.
5. If H=12, then:
B=60/H
B=60/12
B=5
6. Therefore, <span>the possible base and height of a second triangle is:
</span>
B=5
H=12
