Answer:
These two triangles are similar because they have 3 angles in common.
Step-by-step explanation:
We can tell this since they both have right angles in them. We also know that angle X and U are the same since they have the notation. And since all triangles add up to 180, and if the other two angles are the same, then the final angle must be the same too.
36.25/5 = 7.25
The first digit of the quotient is in the ones. Paul is correct.
Answer:
Step-by-step explanation:
The sum of those numbers is 14. Let's divide 14000 by 14 to get the number of parts (each part will be an investment in dollars) and we get 10,000. So if a person invests 2 parts, he invests 2(10,000). A person that invests 5 parts invests 5(10,000), and likewise for the person investing 7 parts: 7(10,000). That gives us 20,000 + 50,000 + 70,000 = ?
(140,000)
The difference in investment between the largest and the smallest is 50,000
Answer: x = -1/8
Step-by-step explanation:
Given the equation 9^x+1 - 13(3^x)+4=0
First, open the bracket, multiply 13 by 3
9^x+1 - 39^x+4=0
Combine like terms
9^x - 39^x +4 +1=0
40^x+5=0
Make x the subject
40^x=0 -5
40^x= -5
Divide both sides by 40
40^x/40=-5/40
x = -1/8
I hope this is clear, please mark as brainliest answer.
