Only hash channel catfish typically was about 0.06 g during the first six weeks of life at weight increase about 10% each day right a exponential model for the weight how much will the catfish gain weight after six weeks

Answers

Answer:

3.225 gram

Step-by-step explanation:

Given that :

Initial weight = 0.06g

Rate of increase, r = 10% = 0.1 per day

Weight gain after 6 weeks

For an exponential model. f(x)

f(x) = a(1 + r)^x

Where ; a = initial amount ; r = growth rate ; x = period

Our model becomes :

f(x) : 0.06(1 + 0.1)^x

f(x) = 0.06(1.1)^x

Number of days in 6 weeks = 6*7 = 42 = x

f(42) : 0.06(1.1)^42

= 3.285 gram

Hence, weight gain after 6 weeks :

(3.285 - 0.06) g = 3.225 gram

There were 220 people who voted at the 6th grade meeting. Sixty percent of the voters are in favor of changing the school mascot. How many people are against changing the mascot? Use numbers and words to explain your answer.

Answers

Step-by-step explanation:

First I had to find 60% of 220.

220 × .60 = 132.

132 people are in favor so I have to subtract that number from 220 to find how many people were against.

220-132 = 88

88 people were against changing the mascot.

The first snack is 270 calories for 3 servings, and the second snack is 450 calories How many servings does the snack have to have in order to equivalent to the first snack?

Answers

Answer:

5 servings

Step-by-step explanation:

Given that:

For a particular first snack to be = 270 calories;

the servings = 3

Then, for the second snack, the calories = 450.

To estimate the servings for the second snack; we need to equate the first snack with the second snack.

Let y be the value of the unknown second snack

Then:

270 calories = 3 servings

450 calories = y servings

y servings = (450 calories × 3 servings) / 270 calories

y servings = 5 servings

Thus; the second snack needs to have 5 servings in order to be equivalent to the first snack

The sum of two numbers is 46 and their
difference is 20. What is the smaller
number?
1
A) 40
B) 13
C) 26
D) 12

Answers

46/2 is 23
20/2 is 10
The number is + or - 23
So 13 and 33
13

Answer:

B. 13

Step-by-step explanation:

We have two unknown numbers, let's have two variables for these two unknown numbers, X and Y.

"The sum of two numbers is 46 and their difference is 20."

Meaning we have two equations :

X + Y = 46

X - Y = 20

Looking at the last part of "their difference is 20." We can assume X = Y + 20

So substitute the assumed equation into X + Y = 46

(Y + 20) + Y = 46

2y + 20 = 46

Subtract 20 from both sides :

2y = 26

Divide 2 by both sides :

y = 13

There you go.
