Answer:

% Calories of carbohydrates=54%

So option C is correct which is 54%

Step-by-step explanation:

In order to find the kilocalories of carbohydrates in the dinner we first have to convert grams of carbohydrates,protein and fat into kilocalories.

1 gram of carbohydrate≈ 4 kilocalories

1 gram of protein≈ 4 kilocalories

1 gram of fat≈ 9 kilocalories

Calories in 210 grams of Carbohydrates=210*4=840

Calories in 60 grams of protein=60*4=240

Calories in 52 grams of fat=52*9=468

Total Calories=Calories of carbs+Calories of protein+Calories of fat

Total Calories=840+240+468

Total Calories=1548

% Calories of carbohydrates= (Calories of carbohydrates/Total Calories)*100

% Calories of carbohydrates=(840/1548)*100

% Calories of carbohydrates=0.54*100

% Calories of carbohydrates=54%

So option C is correct which is 54%

common difference, d = -3

f1 = -13

An arithmetic sequence f(n) = f1 + d(n - 1)

so f(n) = -13 - 3(n - 1)

f(46) = -13 - 3(46-1) = -13 -3(45) = -13 - 135 = -148

Answer:

f(46) = - 148

A line passes through the point (0,2) and has a slope of -1/2 what is the equation of the line
emmasim [6.3K]

Answer:

y = -1/2x + 2

Step-by-step explanation:

A line in slope-intercept form in y = mx + b

"m" is the slope

"b" is the y-intercept

x and y represent points on the graph

To write an equation, you need "m" and "b".

We already know m = -1/2

The point (0, 2) is the y-intercept. The y-intercept occurs when x = 0.

Points are in the form (x , y), so x = 0 and y = 2.

Therefore b = 2.

Substitute m = -1/2 and b = 2 into the equation:

y = mx + b

y = -1/2x + 2

Answer:

c = -13.78.

Step-by-step explanation:

21.2x + c  ≡ 5.3(4x - 2.6)

21.2x + c  ≡ 21.2x - 13.78

Equating constant terms:

c = -13.78.
