Answer:
20 × 10 = 200
Step-by-step explanation:
Multiply 2 × 1 = 2 and then add the two zeros onto the end to get 200.
Answer:
Step-by-step explanation:
factors of 84 = 2* 2 * 3 * 7
1) 21 *4 ===> 21 beads , 4 rows
2) 14 * 6 ===> 14 beads , 6 rows
3) 12 * 7 ===> 12 beads, 7 rows
<h3><u>S</u><u>olution</u></h3>
1). 1/3 + 1/5 = (5 + 3)/15
= 8/15. Ans.
2).
==> 3/5 - 1/6
= (3×5 - 5)/30
= (15 - 5)/30
= 10/30
= 1/3 Ans.
3).
==> 2/3 ÷ 3/4
= 2/3 × 4/3
= 8/9 Ans.
4).
==> 3/8 + 5/12
= (3×3 + 10)/24
= (9+10)/24
= 19/24 Ans.
5).
==> 5/16 - 3/32
= (5×2 - 3)/32
= (10-3)/32
= 7/32 Ans.
Answer:
x=−4+√22 or x=−4−√22
Step-by-step explanation:
Substitute all values in the quadratic formula.
Solve.
The sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r), a=initial term and r=common ration so
s(n)=20(1-0.25^n)/(1-0.25)
s(5)=20(1-0.25^5)/(0.75)
s(5)=26.640625
