Answer:

The total number of seashells in Sally’s collection after 5 weeks is 225 and an expression to represent the total number of seashells in Sally’s  collection after w weeks is  y = 100+25w

Step-by-step explanation:

Sally has seashells currently = 100

From today , she will collect 25 seashells each week.

Let w be the no. of weeks

So, she will collect seashells in w weeks = 25w

So, total seashells after w weeks = 100+25w

Let y denotes total seashells after w weeks

So, y = 100+25w

Substitute w = 5

y = 100+25(5)

y = 225

Hence the total number of seashells in Sally’s collection after 5 weeks is 225 and an expression to represent the total number of seashells in Sally’s  collection after w weeks is  y = 100+25w

Ok so sally has 100 seashells to start with. Now every week she is going to collect 25 seashells each week and we want to work out how many seashells she has over 5 weeks
So...
1 week-25 seashells
5 weeks-125 seashells
So that’s 5x25 which=125
But she already has 100 seashells to start with so you need to add them on so
125+100=225 seashells after 5 weeks

Answer:225 seashells after 5 weeks

ebony wants to buy a dvd player and dvds the equation relates the total cost for dvds and dvd player and N dvds is p=20n+200 wha
kupik [55]

____________________________________________________

Answer:

It represents the cost of the DVD player.

____________________________________________________

Step-by-step explanation:

The reason why it represents the cost of the DVD player is because in the question, it doesn't mention anything about buying multiple DVD players. Ebony would need to buy many DVD's, but doesn't need many DVD players because ebony could use one for all of the DVD's. If you noticed in the question, it says "a DVD player," what  this means is that Ebony is only going to buy one DVD player, since it's singular (without and s at the end).

The equation is saying that she starts off with buying 1 DVD player for 200 dollars; and, she is buying n (number of DVDs) for 20 dollars each.

This shows that the 200 in the equation in the question represents the cost of the DVD player.

Men and women (ages 22–40) were surveyed to choose a favorite free-time activity: playing sports, dancing, or watching movies/TV
Gnesinka [82]

The correct two-way frequency table for the data is <u>Men </u><u>and </u><u>Women </u><u>Leisure Time Activity Preferences.</u>

<h3>What is a correct two-way frequency table?</h3>

A correct two-way frequency table displays frequencies for two categories (rows and columns) collected from categorical variables (men and women).

Men and Women Leisure Time Activity Preferences;

                Playing Sports     Dancing     Watching movies/TV   Row totals

Men                  11                         3                          6                          20

Women             5                       16                          9                          30

Column totals 16                       19                         15                          50

Hence, the correct two-way frequency table for the data is Men and Women Leisure Time Activity Preferences.

An ant has a mass of approximately 4 × 10–3 grams and an elephant has a mass of approximately 8 x 106 grams. About how many time
Butoxors [25]
Ant's mass: 4 x 10 - 3
Elephant's mass: 8 x 106

First, we should evaluate these expressions by using PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. From P to S is the order that we must follow these steps.

So first for the ant's mass, we have to multiply first since the M comes before the S, resulting in 40 - 3 grams.
Next we have to subtract, leading us to getting 37.

For the elephant since there is only one operation, all we have to do is multiply, which equals 848.

In order to see how many times larger the elephant is than the ant, we have to divide the elephant's mass by the ant's.
848/37 = 22.9

Since you only want an approximate answer, you can put down 23 or even go a bit more vague and put down 20.
