Answer:
6/5m
or
1 1/5m
Step-by-step explanation:
5 - 3 4/5 = x
5/1 - 19/5 = x
5/1(5/5) - 19/5 = x
25/5 - 19/5 = x
25/5 - 19/5 = 6/5
x = 6/5 or 1 1/5

Answer:
144.2 cm
Step-by-step explanation:
Length of the iron rod is 7.4cm
Radius is 3.1m
Therefore the surface area can be calculated as follows
= 2πrl
= 2×3.142×3.1×7.4
= 144.2 I'm
Hence the surface area is 144.2cm
<span>1) Expression given: 20a+15ab+24b
</span>
2) Greates common factor GFC:
i) Coefficients:
20 = 2² × 5 × 1
15 = 3 × 5 × 1
24 = 2³ × 8 × 1
GCF = common numbers raised to the lower power = 1.
<span /><span /><span />
ii) Letters:
a
ab
b
Since, none letter is in the three terms, then there is not common letter as GFC.
iii) Conclusion the GCF is 1.
<span>
3) Let's see every option of the list:
</span><span>
</span><span>
</span><span>i) The factors common to 20a and 15ab are 1, 5, a, and b.
</span>
FALSE: becasue b is not in 20a.
<span /><span /><span>
ii) The factors common to 20a and 15ab are 1, 5, and a.
</span>
TRUE: 1, 5, and a are in contained in both terms.
<span /><span /><span>
</span><span>iii) The factors common to 15ab and 24b are 1, 3, a, and b.
</span>
FALSE: a is not in 24b
<span /><span /><span>
iv) The factors common to 15ab and 24b are 1, 3, and b.
</span>
TRUE: 1, 3, and b are contained in both terms.
<span /><span /><span>
v) The factors common to 20a and 24b are 1, 2, 4, a, and b.
</span>
FALSE: a is not in 24b and b is not in 20a.
<span /><span /><span>
</span><span>vi) The factors common to 20a and 24b are 1, 2, and 4.
</span>
TRUE: 1, 2, and 4 are contained in both terms.
<span /><span /><span>
vii) The GCF of the expression is ab.
</span>
FALSE: as seen above ab is not a common factor.
<span /><span /><span>
viii) The GCF of the expression is 1
</span>
TRUE: it was proved above.
