Answer: 7

Step-by-step explanation:

Given : The recommended daily allowance for vitamin c is 60 mg per day .

Then, for one whole week , the recommended allowance for vitamin c will be :-

$7\times60=420\text{ mg}$

Also, there are 70 mg of vitamin C per 100 g orange.

1 g = 1000 ml

The proportion of Vitamin C in 100 g = $\dfrac{70}{100000}=0.0007$

1 oz =28.3495 grams

Then, $3\ oz= 3\times28.3495=85.0485 \text{ gm}=85048.5\ mg$

Then, amount of vitamin C in 85048.5 mg = $0.0007\times85048.5=59.53395\approx59.53\ mg$

Then, the number of oranges have to eat each week to meet this requirement= $\dfrac{420}{59.53}\approx7$

Hence, about 7 oranges you would have to eat each week to meet this requirement.

Are these lines parallel or not: L1: (1,2), (3,1), and L2: (0,-1), (2,0)

Phoenix [80]

First find the slope of the first line

m = ( y2-y1)/(x2-x1)

m = ( 1-2)/(3-1)

= -1/2

Now find the slope of the second line

m= ( y2-y1)/(x2-x1)

= ( 0 - -1)/(2 -0)

= (0+1)/(2-0)

= 1/2

Parallel lines have the same slope

These lines do not have the same slope, they are different by a negative sign.

These lines are not parallel.
