Answer:
I would pick a, the estimated total to the nearest dollar is 38
Step-by-step explanation:
13.95 rounded is 14
23.50 rounded is 24
24+14=38
Answer: The value of x will make the triangles similar by the SSS similarity theorem is 30
Third option 30
Solution:
The similarity theorem indicates that the sides of similar triangles must be proportional, then:
x/45=x/45=50/75
x/45=50/75
Solving for x: Multiplying both sides of the equation by 45:
45(x/45)=45(50/75)
x=(45)(50)/75
x=2,250/75
x=30
You can set up an inequality to solve this. You can either do big to small --> 
or small to big --> 
. I'm going to be using big to small because I think it's a little easier.
Cross multiply and you will get:
Isolate x:
x = 
x = 45

Answer:
Step-by-step explanation:
Let the total dimes collected be d.
Let the total quarters collected be q.
Required
Represent as an inequality
The total collection, this year, can be represented as:
From the question, we understand that:
This year's collections is expected to be greater than last year's
This can be represented as:
Substitute in the right values:
Answer:
0.5220
Step-by-step explanation:
Since the probability of contamination is 0.15, the probability of no contamination is 1 - 0.15 = 0.85
The probability that they are all contaminated will be 0.85 * 0.85 0.85 * 0.85 = 0.52200625
This is 0.5220 to four decimal
