Answer: 7 half- gallons of paint
Step-by-step explanation:
3 divided by .5 is 6, so 6 half-gallons will cover the 3 gallons. Another half-gallon is needed to cover the remaining 1/4 gallon needed, and Jade will have 1/4 gallon of paint left.
13. x= 27/4 or 6 and 3/4
14. x= 27
15. x= 191/7 or 27 and 2/7
16. x= 83/15 or 5 8/15
the key to solving these is cross-multiplying and finding a common denominator, you can use photomath if you want to see the solving steps, hope this helps!
the other parallel side is 30 cm
Step-by-step explanation:
here's the solution :-
let the other parallel side be x
now,
=》Area of trapezium =
![\frac{1}{2} \times sum \: of \: parallel \: sides \times height =》[tex] \frac{1}{2} \times (x + 20) \times 16 = 400](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20sum%20%5C%3A%20of%20%5C%3A%20parallel%20%5C%3A%20sides%20%5Ctimes%20height%20%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3E%3D%E3%80%8B%3C%2Fp%3E%3Cp%3E%5Btex%5D%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20%28x%20%2B%2020%29%20%5Ctimes%2016%20%3D%20400)
=》( x + 20 ) × 8 = 400
=》x + 20 = 400 ÷ 8
=》x = 50 - 20
=》x = 30
so length of other parallel side = x = 30 cm
Answer:
₹245 is the cost
Step-by-step explanation:
Given:
Cost of the fan = ₹1470
1/6th = 1470/1 × 1/6
(do not cross multiply and simplify)
= ₹245
