Answer:
1: a
2: a
3: a
4: b
Step-by-step explanation:
a right triangle means the pythagorean theorem applies
a^2 + b^2 = c^2
is true for the triange
a and b are the two shorter sides and c is the long side
test with values to see if true
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
true, it is a right triangle
3 root^2 + 8 root^2 = 11 root^2
3 + 8 = 11
11=11
true, it is a right triangle
3^2+ 10 root^2 = 19 root^2
9 + 10 = 19
19=19
true, it is a right triangle
3^2 + 5^2 = 6^2
9+25= 36
34= 36
false not a right triangle
i hope this helps
Answer:
See below.
Step-by-step explanation:
Convert to decimal form
7 3/5 = 7.6
7 7/10 = 7.7
10 2/5 = 10.4
8 1/2 = 8.5
So the answer is
7 3/5 , 7 7/10, 8.3, 8.1/2, 10.2 10 2/5, 11.1.
Answer:
A. People who are related to the employees of Isaac's Immaculate Ice Cream
Step-by-step explanation:
If the results are called into question, this means there is potential bias in the survey.
Randomly choosing people from a phone book or another random method would not create bias.
Having people blindly test brands of ice cream would not create bias, as it is random and fair.
However, if the people surveyed were related to employees of Isaac's Immaculate Ice Cream, the results could be called into question over a fear of favoritism.
Alright, so I=prt. I is 1090-900=190=interest. It starts at 900, so that is p. R is 0.09. 1090=900*0.09*t, so 1090/(900*0.09)=t=around 13 years
