Your doctor told you to eat 25 grams of fiber each day. You had 66 grams of fiber for breakfast. What percent of the 25 grams of

oksano4ka [1.4K]

To answer the question, divide the amount of fiber taken during breakfast by the total allowable amount then multiply by 100%. This gives us,

(66 / 25) x 100% = 264 %

Thus, the answer is 264%. The answer clearly shows that the fiber taken so far is much more than the total allowable fiber intake.

Form a linear equation in two variables for each of the following :

miv72 [106K]

Step-by-step explanation:

a. (0.60x + 0.70y)- 50 = 10

<=> 0.60x + 0.70y = 60

b. (x+y) = 5(x-y)

x+y=5x-5y

<=> 4x - 6y = 0

Over the interval [0,2pi), what are the solutions to cos(2x) = cos(x)? check all that apply

kykrilka [37]

$\cos(2x) = \cos(x)$

Solution (1)

$2x = x + 2k\pi$

$2x - x = 2k\pi$

$x = 2k\pi$

for k=0 / for k=1 / for k=-1

x=0 / x=2π / x=-2π

acc / acc / rej

solution (2)

$2x = - x + 2k\pi$

$2x + x = 2k\pi$

$3x = 2k\pi$

$x = \frac{2k\pi}{3}$

for k=0 / for k=1 / for k=-1

x=0 / x=2π/3 / x=-2π/3

acc / acc / rej

Note that i'm trying values of K which make the answer belong to our interval;

So our solution which i will represent as a set is;

S € {0,2π/3,2π}
