we will find the area of the trapezium (floor)
I had 98.8m^2( See the work for the solution).
We will then calculate for amount of litres needed for painting . I had 52litres (See the Left hand side for the solution
We will then calculate for the cost
I had £176.696 (see the RHS for solution
Answer:
tan ∅ = 24 / 7
Step-by-step explanation:
cos ∅ = 7 / 25
sin^2 ∅ + cos^2 ∅ = 1
sin^2 ∅ + (7 / 25)^2 = 1
sin^2 ∅ = 1 - 49 / 625
sin^2 ∅ = 625 - 49 / 625
sin^2 ∅ = 576 / 625
sin ∅ = root 576 / 625
sin ∅ = 24 / 25
tan ∅ = sin ∅ / cos ∅
tan ∅ = 24/25 / 7/25
Therefore, tan ∅ = 24 / 7
OPTION 4. 24 / 7
Answer:
96 bars = 10cent each (dime/pence etc) 10.2604166667 each
Step-by-step explanation:
if the cereal bars are accounted for 24inch x 4inch and 4inch lengths seem appropriate length, Then we can account for 1inch x 16 inch widths being 1'' wide each. 6 x 16 = 96 and 96/388 = 4 being the length.
Extended: Area of pan 24 x 16 = 240+148= area of 388in^2
96 bars costing ($9.85) 985/96
Let's take the number as x.
two-fifths of a number = 2x / 5
decreased by 3 = (2x/5) - 3
(2x/5) - 3
(2*25/5) - 3
(2*5) - 3
10 - 3
7
(x + 9) (x - 2)
= x^2 + 7x - 18☺
