Answer:

15/3 + (6.5 + 4.2) - 0.6 = 15.1

Step-by-step explanation:

You can first reduce the fraction to 5 when you multiply by 3, then calculate what's in the parenthesis. So now you have 5 + 10.7 - 0.6, then just solve from left to right. Hope this helps

F(x) = 9x^3 + 2x^2 - 5x + 4 and g(x) = 5x^3 - 7x + 4. What is f(x) - g(x)?

sasho [114]

F(x)= 9x^3 + 2x^2 - 5x + 4
g(x)= 5x^3 - 7x + 4

f(x) - g(x)
9x³ + 2x² - 5x + 4 - (5x³ - 7x + 4)
9x³ + 2x² - 5x + 4 - 5x³ +7x - 4
9x³ - 5x³ + 2x² -5x + 7x + 4 - 4
4x³ + 2x² + 2x

Dorothy's dietary intake for one day consisted of 250 grams of carbohydrate, 60 grams of protein, and 40 grams of fat. What perc

tester [92]

Answer:

$\%Percent = 17.14\%$

Step-by-step explanation:

Given

$Carbohydrate = 250\ g$

$Protein = 60\ g$

$Fat = 40\ g$

Required

Determine the percentage of protein

First, we need to calculate the total:

$Total = Carbohydrate + Protein + Fats$

$Total = 250\ g + 60\ g + 40\ g$

$Total = 350\ g$

Percentage of protein is calculated as thus:

$\%Percent = \frac{Protein * 100\%}{Total}$

$\%Percent = \frac{60 * 100\%}{350}$

$\%Percent = \frac{6000\%}{350}$

$\%Percent = 17.14\%$
