You would get $46.40 back.
Just do 192x0.80=153.60
Then subtract 200-153.60
Answer:
12
Step-by-step explanation:
%100 of it makes 80 then %15 must be 12
Answer:
x = -1/2, 3/4
Step-by-step explanation:
Step 1: Factor
(2x + 1)(4x - 3) = 0
Step 2: Find roots
2x + 1 = 0
2x = -1
x = -1/2
4x - 3 = 0
4x = 3
x = 3/4
Answer:
TAS = 43.99 m²
Step-by-step explanation:
- TSA = total surface area
- Area of a trapezoid = (1/2)(a + b)h
(where a and b are the parallel sides and h is the height) - Area of a rectangle = width x length
This prism is made up of 4 rectangles and 2 congruent trapezoids.
Area of trapezoid = (1/2) x (1.4 + 2.3) x 1.9 = 3.515 m²
⇒ area of 2 trapezoids = 3.515 x 2 = 7.03 m²
Area of base rectangle = 2.3 x 4.8 = 11.04 m²
Area of top rectangle = 1.4 x 4.8 = 6.72 m²
Area of back rectangle = 1.9 x 4.8 = 9.12 m²
Area of sloped rectangle = 2.1 x 4.8 = 10.08 m²
Total surface area = 7.03 + 11.04 + 6.72 + 9.12 + 10.08 = 43.99 m²
Cross multiply:
Distribute 4:
Take away 4xy from both sides:
Take x as the common factor:
Divide both sides by p - 4y :
