The formula for density is given by p=m/v where p is density, M is mass and V is volume. If a substance has a mass of 27.82 grams and a volume of 3.6 ml, what is the most accurate density of the substance in g/ml7.7
7.7278
7.73
0.1

Answers

Answer 1

Answer: p = [27.82] ÷ [3.6]
p = 7.727·
p = 7.728 (3dp)

The answer is B)

Answer 2

Answer:

Answer:

Option 2nd is correct

p = 7.7278 g/ml

Step-by-step explanation:

Formula for the density is given by:

$p = (m)/(v)$ .....[1]

where,

p is the density

m is the mass

v is the volume

As per the statement:

If a substance has a mass of 27.82 grams and a volume of 3.6 ml

⇒ $m = 27.82 g$ and $v = 3.6 ml$

Substitute in [1] we get;

$p = (27.82)/(3.6) = 7.72777778 g/ml$

Therefore, the most accurate density of the substance in g/ml is, 7.7278

The area of the sector formed by the 110 degree central angle is 40 units squared what is the radius

Answers

we know that
area of the circle=pi*r²

if 360° (full circle) has an area of-------------> pi*r²
110°------------------------------> 40 units²
pi*r²=40*360/110--------> pi*r²=130.91------> r²=130.91/pi-----> r²=41.69
r=6.46 units

the answer is
the radius is 6.46 units

In march, a customer spent $8.55 at an office-supply store for some 12-packs of pens. At that time, the store was selling packages of one dozen pens for $1.35. Any customer who bought more than 4 packages, received a discount of $0.30 on the price of each package in excess of 4 packages. In september, the same customer went back to the store to buy the same number of pens. By then, the price per 12-pack of pens had been raised to $1.50 each, with the same discount for more than 4 packages. How much more did the customer have to pay in September than in March?

Answers

We can start by making an equation from the information given on the month of March to find how many packs he bought.
$4(1.35)+x(1.05)=8.55$ This equation shows that for the first 4 packs he bought, he payed $1.35. Then, consequently, for each pack after that, he payed $0.30 less, and we don't know how many more he bought, so we set it up as shown. Finally, we set it all equal to $8.55 since that's how much he payed that month. We get that x=3, meaning that he bought a total of 7 packs of pens that month.
Knowing this, we can now make an equation for the month of September.
$4(1.50)+3(1.20)=x$ This time, we know the entire left side, that he paid $1.50 for the first 4 packs and $0.30 less for the last 3. We get x=$9.60
Knowing this, we can subtract the amount he paid in September by the amount he paid in March to get the answer... $9.60-$8.55=$1.05

If each lap around a track is 400 meters long, how many laps equal 3.1 miles? Round to the nearest tenth. (Hint: 1 foot = 0.3048 meter)

Answers

Answer:

129.032258064516129

Step-by-step explanation:

Final answer:

To convert 3.1 miles into laps on a 400m track, we first convert miles to meters, getting approximately 4988.954 meters. Dividing by 400 meters per lap, we find the distance is approximately 12.5 laps.

Explanation:

The first step is to convert miles into meters, because the laps are measured in meters. There are approximately 1609.34 meters in a mile. So, 3.1 miles would be approximately 4988.954 meters (3.1 x 1609.34 = 4988.954).

As each lap is 400m, we can determine the number of laps by dividing the total distance in meters by the length of one lap. So, 4988.954 meters divided by 400 meters per lap gives us approximately 12.5 laps. Since we need to round to the nearest tenth, our final answer becomes 12.5 laps.

Simone has 5 employees in her flower shop. Each employee works 6 4/15 hours per day. How many hours, in total, do the 5 employees work per day?

Answers

to find the answer of that, you need to multiply 6 4/15 by 5 (can be counted as 5/1)
that will need some steps
----------------------------------------------------------.
step1) convert the mixed numbers into fractions (inproper)
6 4/15 will be converted into 94/15. (this step is explained at the bottom)
-----------------------------------------------------------.
step2) normally multiply numerator with numberator and denominator with denominator.
the answer will be 470/15 which will be simplified into 94/3
-----------------------------------------------------------------.
step3) covert the fraction back to mixed number
that will make it 31 3/4 (but in decimal wise, it will be 31.3 on repeat)
______________________________________________________________
to convert a mixed number into a fraction you will need to:
multiply the denominator with the whole number, and then add the numerator. the denominator of that fraction will be the same denominator it had before.
for example: to convert 3 1/4 into a fraction (improper) you will need to multiply the denominator (4) with the whole number (3) so that will make 12. next you will add the numerator (1) which will make it 13/?. 13 over what? 13 over the same denominator it had before. lets go back and see. so it had 4 as a denominator, so it will be 13/4.
