Answer:
Ed and Sheerie save 7.5%.
Step-by-step explanation:
This question can be solved using a rule of three.
Ed and Sherrie save $90 each pay period from their combined paychecks, which total $1200. What percent do Ed and Sherrie save?
How much of $1200 is $90? $1200 is 100% = 1, $90 = x. So
$1200 - 1
$90 - x
Ed and Sheerie save 7.5%.
You got this you can do it I don’t know the answer but I hope you find someone who does(:
Answer:
502 m²
Step-by-step explanation:
We require to find b before calculating the surface area.
The volume (V) of a cuboid is calculated as
V = lbh ( l is length, b is breadth and h is height )
Here V = 510, l = b, b = 10 and h = 3, thus
b × 10 × 3 = 510
30b = 510 ( divide both sides by 30 )
b = 17
--------------------------
The opposite faces of a cuboid are congruent, thus
top/bottom area = 2(17 × 10) = 2 × 170 = 340 m²
front/back area = 2(17 × 3) = 2 × 51 = 102 m²
sides area = 2(10 × 3) = 2 × 30 = 60 m²
Surface area = 340 + 102 + 60 = 502 m²
Step-by-step explanation:
Tn= a+(n-1)d
= 123 +(70-1)7
=123+(69)7
=123+483
