Only one, because the sum of the 2 shorter sides must be greater than the longest side. So 11+16>26 and the sums of the other sides together are less than the third side. So only ONE triangle can be made.
Answer:
14. 28 inches
15. 6.3 cm
16. 1/2 yard
Step-by-step explanation:
14. use the pythagorean theorem for this problem
a^2 + 45^2 = 53^2
you get a^2+2025=2809
subtract 2025 from both sides to get
a^2=784
square root both sides to get 28
15. same thing as question 14
1.6^2+b^2=6.5^2
2.56+b^2=42.25
subtract 2.56 from both sides
b^2=39.69
square root both sides to get your answer
b = 6.3cm
16. again use the pythagorean theorem
.3^2+.4^2=c^2
.09+.16=c^2
.25 = c^2
square root both sides to get
c = .5
or
c = 1/2 yard
Answer: Option 3
Step-by-step explanation:
You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount. You only multiply or divide, never add or subtract, to get an equivalent fraction.
I hope this helps.
Is 6/2(2+1) 1 or 9? I will tell you why it should be one:
6/2a = 3/a. Let a = 2+1.
