A desk is purchased for $277. Calculate it's worth after depreciating for 5 years if it's depreciation rate is 20% per year

The store is selling lemons at $0.58 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough l

avanturin [10]

Answer:

$4.64

Step-by-step explanation:

1 cup = 16 tablespoons

$\frac{1}{2}$ cup = 8 tablespoons

Each lemon yields about 2 tablespoons of juice. You need 8 tablespoons for one lemon pie, so you need $8\div 2=4$ lemons for one pie and $4\times 2=8$ lemons for two pies.

The store is selling lemons at $0.58 each, hence, 8 lemons will cost

$\$0.58\times 8=\$4.64$

Find the mean of each distribution.

Vanyuwa [196]

Answer:

a) 23 °C

b) 5.81 m² (2 dp)

Step-by-step explanation:

This set of data is presented as a <u>Dot Plot</u>.

The frequency (how often a data value occurs) is represented by the number of dots above each data value.

For example, in this dot plot, there are 3 dots above the data value 21 °C and so this means that there are three of this particular data value in the set of data.

To find the mean, we need to multiply each data value by its frequency, add them up, then divide by the total frequency.

$\begin{aligned}\textsf{mean}&=\dfrac{3 \times 21+1 \times 22+2\times 23+5\times 24+1\times 25}{3+1+2+5+1}\\\\ & = \dfrac{63+22+46+120+25}{12}\\\\& = \dfrac{276}{12}\\\\&=23^{\circ} \sf C\end{aligned}$

This set of data is presented as a <u>stem and leaf diagram</u>, where the units and tenths are split. The units column is the 'stem' and the tenths become the 'leaf'.

Therefore, the first row of this stem and leaf diagram represents 2 data values: 4.3 and 4.8

To find the mean, sum the data values, then divide by the total frequency.

To find the total frequency, simply count the number of values in the leaf part of the diagram.

Data values = 4.3, 4.8, 5.1, 5.1, 5.2, 5.5, 5.7, 6.6, 6.9, 7.3, 7.4

Total frequency = 11

$\begin{aligned}\textsf{mean} &=\dfrac{4.3 + 4.8 + 5.1+5.1+5.2+5.5+5.7+6.6+6.9+7.3+7.4}{11}\\ & = \dfrac{63.9}{11}\\\\& = 5.81\:\textsf{(2 dp)}\end{aligned}$

John Jogger purchased a three-year membership at a local fitness center at the beginning of the year. It cost him $395 per year.

balu736 [363]

1. We need to find how many times John Jogger went to the gym.

He goes 2x weekly for 13 weeks.

13 x 2 = 26 times in the first 3 months.

We still have another 9 months left. He goes twice monthly for each month.

9 x 2 = 18.

We add the total times he went to the gym for the first 3 months to the other 9 months in the year.

26 + 18 = 44 times in one year. If we repeat this for 3 years, you get 44 x 3 = 132 gym visits in three years.

The gym membership is $395 per year. For three years this is 395 x 3 = $1185.

He went to the gym 132 times for a total of $1185. To find the price per visit, divide the total price by the amount of times he went to the gym.

1185/132 = ~$8.98 per gym visit.

2. If 13 weeks = 3 months (1/4 of a year), then there are 52 weeks per year.

If he goes twice every week for 52 weeks, that's 52 x 2 = 104 times per year. If he kept this up for three years, that's 104 x 3 = 312 gym visits in three years.

At the price we found earlier of $1185 for a three-year membership, divide the price by the total number of visits to find the price per visit.

1185/312 = ~$3.80 per gym visit.

Can someone give a correct answer to this? idk what im doing! thanks :)

The regular rolls are 15x - 2y = 4

The vegetarian rolls 20x - 3y = 1

So the values are:

x = 2 and y = 13

The result is, 2 chefs and 13 customers.
