Mike is catering a party. He plans on having 4 trays of 5 appetizers each on the buffet at the beginning of the party and will rotate in new trays as those become empty. To ensure that he does not run out of appetizers during the party, he is going to make 2 appetizers per person in addition to the initial number put out on the buffet. Which of the following represents A, the amount of appetizers Mike needs to make, in terms of p, the amount of people attending the party?

Answers

Answer:

A = 20 + 2p

Step-by-step explanation:

I can’t see tour answer choices, but I’ll give an equation that will hopefully match one. Feel free to add in the comments what the answer choices are, and I will follow up.

A = 4(5) + 2p
A = 20 + 2p
A = 2p + 20
A = 2(p + 10)

I’m getting the 20 from the 4 trays of 5 appetizers on the buffet. I’m getting the 2p from the “two appetizers per person”

During a 40% off sale, Tessa pays $24 for a sled. What was the original price?

Answers

Answer:

$33.6

Step-by-step explanation:

the 1.4 represents the added 40% to find the original price of the sled

Answer:

original price = 40

Step-by-step explanation:

make an equation using the information given in the question, x will represent the original price

x - 0.4x = 24

x - 2/5x = 24

solve for x

x - 2/5x = 24

3/5x = 24

x = 40

Part A: Let y represent the number of rabbits after x years. Which functioncan be used to model y as a function of x, where x is a non negative number ?

А. y = 10 (3) ^ (x - 1)

В. y = 10 (3) ^ x

C. y = 3 (10) ^ (x - 1)

D . y = 3 (10) ^ x

Answers

Answer:

y = 10(3)x

Step-by-step explanation:

The exponential function that can represent the population of rabbits after [x] years is y = 10(3)ˣ.

What do you mean by domain and range of a function?

For any function y = f(x), Domain is the set of all possible values of [x] for which [y] exists. Range is the set of all values of [y] that exists for the given domain.

Given is rate of increase of a rabbit's population.

The exponential function that can represent the population of rabbits after [x] years can be written as -

y = 10(3)ˣ

Refer to the graph attached.

Hence, the exponential function that can represent the population of rabbits after [x] years is y = 10(3)ˣ.

For rectangle ABCD, find m∠ADB.

Answers

Answer:

we know all angles are 90° in the rectangle

therefore, angle d = bdc+bda = 90

=> 31+bda = 90

=>angle bda= 59

The measurement of the angle ADB should be considered as the 59 degrees.

Calculation of the measurement of the angle ADB:

Since we know that all angles in the rectangle should be of 90 degrees

So,

Here angle d = bdc + bda

= 90

Now

31 + bda = 90

So, bda = 90 - 31

= 59

hence, The measurement of the angle ADB should be considered as the 59 degrees.
