150 is 25% of what number? Four students solved this problem using equivalent ratios. Choose the student whose work is correct.

Liam's work. StartFraction part Over whole EndFraction = StartFraction 25 times 6 Over 100 times 6 EndFraction = StartFraction 150 Over 600 EndFraction Yasmin's work. StartFraction part over whole EndFraction = StartFraction 25 times 6 Over 150 times 6 EndFraction = StartFraction 150 Over 900 EndFraction Bill's work. StartFraction part Over whole EndFraction = StartFraction 100 divided by 5 Over 25 divided by 5 EndFraction = StartFraction 20 Over 5 EndFraction Isabella's work. StartFraction part Over whole EndFraction = StartFraction 150 divided by 6 Over 100 divided by 6 EndFraction = StartFraction 25 Over 16.67 EndFraction

If f(1) = 160 and f(n + 1) = –2f(n), what is f(4)?
lions [1.4K]

Answer:

-1280

Step-by-step explanation:

There are 2 ways you could do this. You could just do the question until you come to the end of f(4). That is likely the simplest way to do it.

f(1) = 160

f(2) = - 2 * f(1)

f(2) = -2*160

f(2) = -320

f(3) = -2 * f(2)

f(3) = -2 * - 320

f(3) = 640

f(4) = - 2 * f(3)

f(4) = - 2 * 640

f(4) = - 1280

I don't know that you could do this explicitly with any real confidence.

Inequalities help us to compare two unequal expressions. The inequality for this scenario in standard form is 2x + 3y > 30.

<h3>What are inequalities?</h3>

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.

It is mostly denoted by the symbol <, >, ≤, and ≥.

Let the safety counts be represented by x, while the field goal count is represented by y.

Part A: The inequality for this scenario in standard form.

2x + 3y > 30

Part B: The inequality in slope-intercept form.

2x + 3y > 30

3y > 30 - 2x

y > 10 - (2/3)x

y < (2/3)x - 10

PartC: The inequality is represented below.

Which best describes the relationship between the successive terms in the sequence below? –3.2, 4.8, –7.2, 10.8, …
Leto [7]
Since you are not given the following choices, by analyzing this series, it is a geometric progression because their common ratio is constant. Proofing that
4.8/(-3.2) = -1.5, also
-7.2/(4.8) = -1.5, and also
10.8/(-7.2) = -1.5
