Mathematics

posledela2 years ago
3 0

Answer:

17.5 milies

Step-by-step explanation:

80/4

=20/1

This means that Ivan can walk 1 mile in 20 minutes

To figure out how many miles Ivan can walk in 345 if she continues at that pace you divide 345 by 20

345/20 = 17.5

This means Ivan can walk 17.5 milies in 345 minutes

Aleesia has a box of 52 muffins. She wants to put out plates that each have the same number of muffins. What is one possible way
Brums [2.3K]

Answer:

4 muffins per plate (13 plates)

Other answers are possible. See below

========================================================

Explanation:

The factors of 52 are: 1, 2, 4, 13, 26, 52

If Aleesia picks any of those values, then she will divide the muffins up equally.

For example, if she puts 4 muffins per plate, then that means she'll have 13 plates since 4*13 = 52.

Or she could put 2 muffins per plate to get 26 plates (because 2*26 = 52).

Side note: A prime factor tree might be helpful.

F’(x)= 1+3 square root x f(9)=68
notka56 [123]

Answer:

f(x) = x + 2x^\frac{3}{2} + 5

Step-by-step explanation:

I'm assuming the question here is asking for f(x)

The first step would be to find the antiderivative of f'(x)

\int{1+3\sqrt{x}} \, dx = \int{1 + 3x^\frac{1}{2}} dx

Apply the reverse power rule

x + 2x^\frac{3}{2} + C

Now solve for C when x = 9

x + 2x^\frac{3}{2} + C = 68\\9 + 2(9)^\frac{3}{2} + C = 68\\9 + 2(27) + C = 68\\9 + 54 + C = 68\\63 + C = 68\\C = 5

Now substitute into the antiderivative

f(x) = x + 2x^\frac{3}{2} + 5

A nonnative fern species is introduced into an area and quickly begins to spread. The number of plants can be modeled by
ivolga24 [154]

Based on the information, there were initially 1200 ferns; the monthly percent rate of change is 68% and this situation is modeled by an exponential growth function

<h3>How to complete the information?</h3>

The given parameters from the question are:

P(n) = 1200(1.68)^n

Where

n represent the number of months

An exponential growth function is represented as:

P(n) = a * (1 + r)^n

Where

a represents the initial value

r represents the rate

By comparison, we have

a = 1200

1 + r = 1.68

This gives

r = 0.68 = 68%

Hence, there were initially 1200 ferns; the monthly percent rate of change is 68% and this situation is modeled by an exponential growth function
