will likes two brands of healthy breakfast cereal. in superfiber cereal, there are 5 grams of fiber in one cup. in fiber oats cereal, there are 4 grams of fiber in one cup. let x represent the number of cups of superfiber will ate this week and let y represent the number cups of fiber oats he ate this week. which inequality represents the situation if the cereal will ate this week contained at least 30 grams of fiber? a)5x + 4y ≥ 30b)4x + 5y ≥ 30c)4x + 5y ≤ 30

Let x  represent the number of cups of Superfiber Will ate this week and let y  represent the number cups of Fiber Oats he ate this week.

1. If in Superfiber cereal, there are 5 grams of fiber in one cup, then in x cups there are grams of fiber.

2. If in Fiber Oats cereal, there are 4 grams of fiber in one cup, then in y cups there are grams of fiber.

3. The total amount of fiber Will ate is grams.

4. This week Will ate at least 30 grams of fiber. Then

correct choice is A.

the inequality is:  a)5x + 4y ≥ 30

Step-by-step explanation:

Hi, to solve this problem we have to analyze the information given:

So, the cereal Will ate this week contained at least 30 grams of fiber. At least means more or equal ( ≤ 30 ).

If each cup of Superfiber cup has  5 grams of fiber ⇒ 5x

If each cup of Fiber Oats cup has  4 grams of fiber ⇒ 5y

Finally, the inequality is:

a)5x + 4y ≥ 30

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
