we have
------> inequality A
The solution of the inequality A is the shaded area below the solid red line
see the attached figure N
------> inequality B
The solution of the inequality B is the shaded area above the dotted blue line
see the attached figure N
therefore
The solution of the system of inequalities is the shaded area between the solid red line and the dotted blue line
see the attached figure N
therefore
the answer in the attached figure N
Simple,
first find what 19*7 and 3*5 is,
19*7=133
and
3*5=15
Factors in 133:
1,7,19,133
Factors in 15:
1,3,5,15
The GCF of 133 and 15 is 1. You can't simplify/reduce it anymore.
Answer:
8.1
Step-by-step explanation:
Use Pythagoras to find the length of BD- 7.5^2 +5^2=81.25
The square root of 81.25 is 9.01
BD-9.01 cm
Then use the cos rule to find BC.
c=a2+b2﹣2abcosγ=9.012+132﹣2·9.01·13·cos(38°)≈8.09819(square root)
round to 8.1
Answer:
24
Step-by-step explanation:
14.4 as a fraction would be 14 2/5. You just need a fraction larger than that, so there are infinite possibilities. Whether you are writing it as a fraction or decimal though is what I need to know. You could do 16.2, which is 16 1/5 as a fraction. Or 18.9, 18 9/10 as a fraction.
