So the first answer is 65+50m because its 65 dollars for sign up PLUS 50 PER month. and 20+55m. The second question is saying that both the gyms have the same price, so I will say that its 50+ 20m for both. It represents the total cost of the gym membership that you have to pay. Hope this helped.

Answer:

least to greatest: {61, 61, 61, 178, 179}

Step-by-step explanation:

If the third-largest angle is 61°, the smallest three angles cannot be larger than 183°. Since the total of all angles must be 540°, and the total of the largest two cannot be greater than 179°×2 = 358°, the sum of the smallest three must be at least 540° -358° = 182°.

So, the possible sets of angles with the smallest 3 totaling 182° or 183° are (in degrees) ...

{60, 61, 61, 179, 179} . . . . two modes

(61, 61, 61, 178, 179} . . . . . one mode -- the set you're looking for

A town has a population of 12000 and grows at 5% every year. What will be the population after 12 years, to the nearest whole nu

Marizza181 [45]

Answer:

21,550

Step-by-step explanation:

An increase of 5% means the population is multiplied by 100% +5% = 1.05. This occurs each year for 12 years, so the multiplier is ...

1.05¹² ≈ 1.7958563

When the initial population is multiplied by this factor, it becomes ...

12,000×1.7958563 ≈ 21,550

A farmer owns pigs, chickens, and ducks. When all her animals are together, she has 30 feathered animals, and the animals all to

tatiyna

To solve this problem, let us first assign some variables. Let us say that:

x = pigs

y = chickens

z = ducks

From the problem statement, we can formulate the following equations:

1. y + z = 30 ---> only chicken and ducks have feathers

2. 4 x + 2 y + 2 z = 120 ---> pig has 4 feet, while chicken and duck has 2 each

3. 2 x + 2 y + 2 z = 90 ---> each animal has 2 eyes only

Rewriting equation 1 in terms of y:

y = 30 – z

Plugging this in equation 2:

4 x + 2 (30 – z) + 2 z = 120

4 x + 60 – 2z + 2z = 120

4 x = 120 – 60

4 x = 60

x = 15

From the given choices, only one choice has 15 pigs. Therefore the answers are:

She has 15 pigs, 12 chickens, and 18 ducks.

Measurement: Customary Units", then answer each of the following questions. Round answers to the nearest hundredth, if necessary

Neporo4naja [7]

Solution

For this case we have the following amount: 35 pints

We want to convert this into quarts so we can do this:

$35Pts\cdot\frac{1quart}{2Pts}=17.5\text{quarts}$

Then the answer rounded to the nearest hundredth is:

17.50 quarts
