So the first one is -0.5 and second is -0.5 the third one is -0.5 and the fourth is -0.25 so I would say that is D
Answer:
See below in bold.
Step-by-step explanation:
The triangular piece of cloth is a right triangle because 41^2 = 40^2 + 9^2 (By the Pythagoras theorem).
So the area of one piece = 1/2 * 9 * 40 cm^2.
The total amount of cloth required for one umbrella = 10 * 1/2 * 9 * 40
= 1800 cm^2.
The total cost = 1800 * 0.25 = Rs 450.
Step-by-step explanation:
Given that,
The mass of a patient = 70 kg
A 70kg patient has approximately 8 pints of blood.
The patient donates 470mL of blood.
We know that,
1 pint = 568 mL
8 pints = 4544 mL
Required fraction,
So, the required fraction is approximately 
.
I'm not sure what you are looking for but I'll answer this question based on what I think is needed.
Given:
Day 1: 130
Day 2: 130 x 4 = 520
Day 3: 520 x 4 = 2,080
The exponential equation of this problem is:
V(n) = 130(4)^n
Where n is the number of days since the video was first shown.
Let us assume that 10 days have past. Total view would be:
V(n) = 130(4)^n
V(10) = 130(4)^10
V(10) = 130(1,048,576)
V(10) = 136,314,880
After 10 days, there are more than 136 Million views of the viral video.
2x - 15
15 is decreased that is the key word here which indicates subtraction.
twice a number with given variable x is 2x
subtraction always goes behind so 2x - 15
