Answer:
- Son washed more
- Remaining 9/28 of the laundry
Step-by-step explanation:
<u>Make denominators common to see the difference in fractions:</u>
Son washed more laundry as 12/28 > 7/28
<u>Together they washed:</u>
- 7/28 + 12/28 = 19/28 of the laundry
<u>Remaining part is:</u>
- 1 - 19/28 =
- 28/28 - 19/28 =
- 9/28 of the laundry
Answer:
a₁ = 6
Step-by-step explanation:
The sum to n terms of a geometric sequence is
= 
where a₁ is the first term and r the common ratio
Here
= 1530 and r = 2, thus
= 1530 , that is
a₁ (256 - 1) = 1530
255a₁ = 1530 ( divide both sides by 255 )
a₁ = 6
answer
z = 100
opposite angles
when inscribed in a circle, the opposite angles of a quadrilateral add up to 180
so z + 80 = 180 and y + 120 = 180
solve for z
z + 80 = 180
z = 180 - 80
z = 100
