Answer:
157.62
Step-by-step explanation:
I took the mass(g) of 34.932 and divided it by the volume of 4.1
[tex]\frac{34.932}{4.1} =8.52[/tex]
To prove that this was correct I did the same thing for the next row
[tex]\frac{47.712}{5.6} =8.52[/tex]
I took 8.52 and multiplied it by the volume of 18.5 to get the mass.
[tex]8.52*18.5=157.62[/tex]
The mass is 157.62
hope this helps! :))

Answer:
The minimum width of the book = 20.9 cm
Step-by-step explanation:
The length of the book cover = 28.3 cm
The width of the book cover = 21 cm
Given that the uncertainty in measurement should be included due to the likelihood of error in measurement, the uncertainty in measurement can be presented as follows;
Measurement = (Best estimate + Uncertainty) units
Whereby the display of the measuring device is limited to one decimal place, we can have the measurement of the width, w, as follows;
Width of the book = (21 ± 0.1) cm
The range of the width of the book is therefore 20.9 cm to 21.1 cm
The minimum width of the book = 20. cm

The Y-intercept of a line is where the line intersects with the y-axis, it is also when x=0. To find the intercept simply go along the axis until you run into the line, in this case, you hit the line when y=4. If the intercept is not shown on the graph you can use the slope-point equation and then simplify for the intercept.

3. A random survey of the quality of Raleigh city parks is taken. Sixty-five percent of the people surveyed were pleased with the condition of the parks. If 280 people were surveyed, then how many were pleased?
Answers
Answer: 182 people
Step-by-step explanation:
The following can be deduced from the question:
Number of people surveyed = 280
Percentage of people pleased = 65%
The number of people that were pleased will be:
= Percentage of people that were pleased × Number of people surveyed
= 65% × 280
= 65/100 × 280
= 0.65 × 280
= 182
182 people were pleased with the condition of the park

so you add $14.25 + 3.89 and you get the amount mike paid for food which is $18.14
2 * $4.39 = $8.78 for sodas

4. Marlene purchases dollars worth of stock on her broker's advice and pays her
broker a 1.5% broker fee. She sells her stock when it increases to y dollars two
years later, and uses a discount broker who charges $21 per trade.
A. Express Marlene's net proceeds algebraically.
Answers
Answer:
y - 1.015x - 21
Step-by-step explanation:
Given that:
Let worth of stock = x
Broker fee = 1.5% of x = 0.015x
Total cost incurred to purchase stock = x + 0.015x = 1.015x
Worth of stock after 2 years = y
Broker fee = $21 per trade :
Amount Realized from sale = y - $21
Net proceed = Amount Realized from sale - cost incurred to purchase
= (y - 21) - (1.015x)
= y - 21 - 1.015x
= y - 1.015x - 21

The lengths of the sides of a quadrilateral are 4 consecutive even integers. The perimeter of the quadrilateral is 36 inches. What is the length of the longest side?\
WILL GIVE BRAINLIEST
NEED THIS ASAP
Answers
Answer:
The length of the longest side is 9 inches
Step-by-step explanation:
The given parameters for the quadrilateral is that the length of the sides are;
The length of the sides are consecutive integers = x, x + 2, x + 4, x + 6
The perimeter of the rectangle = 36 inches
The side length to be found = The length of the longest side = x + 3
2 6 10 14 18
∴ x + x + 2 + x + 4 + x + 6 = 36
4·x + 12 = 36
4·x = 36 - 12 = 24
4·x = 24
x = 24/4 = 6
x = 6 inches
The length of the longest side = x + 3 = 6 + 3 = 9
The length of the longest side = 9 inches.
Answer:
The length of the longest side is 9 inches
Step-by-step explanation:
The given parameters for the quadrilateral is that the length of the sides are;
The length of the sides are consecutive integers = x, x + 2, x + 4, x + 6
The perimeter of the rectangle = 36 inches
The side length to be found = The length of the longest side = x + 3
2 6 10 14 18
∴ x + x + 2 + x + 4 + x + 6 = 36
4·x + 12 = 36
4·x = 36 - 12 = 24
4·x = 24
x = 24/4 = 6
x = 6 inches
The length of the longest side = x + 3 = 6 + 3 = 9
The length of the longest side = 9 inches.

Kelsey has to pay $200 to rent a booth at the craft fair. The materials for each pendant cost $7.80, and she plans to sell each pendant for $13.50. To make a profit, she must make more money than she spends. Kelsey has already made 10 pendants.
Part C
It takes Kelsey 5 hours to make 12 pendants. If she works 8 hours per day for 3 days before the craft fair, can she make enough additional pendants to sell so that she can make a profit of at least $50? Explain.
Answers
Step-by-step explanation:
Let's calculate how much she will spend:
She has to pay $200 for the rent.
She made 10 pendants that costed $7.80 each, that's a total of 10*$7.80 = $78.
Therefore, she will spend $200 + $78 = $278.
Let's define x as the amount of pendants she makes.
To make a profit, the amount of pendants she makes, multiplied by $13.50 that is the price, has to be greater than $280 added to the amount of pendants she makes, multiplied by $7.80 that is the cost.
We write that as
13.50x > 280 + 7.80x
Let's subtract 7.80x on both sides:
13.50x -7.80x > 280 + 7.80x - 7.80x
5.70x > 280
Now we divide by 5.70 on both sides:
5.70x/5.70 > 280/5.70
x > 49.1
To make profit, she needs to make and sell more than 49 pendants.

The first step is to convert to decimal numbers
For Lionel
Lionel has read 31.5% of the book.
= 31.5% = 31.5/100 = 0.315
For Jill
Jill has read 1/3 of the book.
= 1/3 = 0.33333333333
= 0.333
For Grace
Grace has read 3/8 of the book.
= 3/8 = 0.375
The, list shows the numbers in order from greatest to least
= Grace, Jill, Lionel
Where Grace is the greatest and Lionel is the least.
