A cork has a mass of 3 grams and a volume of 16 cm3
. Calculate the density.
Answer:
0.1875, or 3/16
Step-by-step explanation:
The formula for density is mass/volume.
I hope this helps :)
Answer:
[tex]{\boxed {\sf \frac{3}{16} \ g/cm^3}}[/tex]
or
[tex]\boxed {\sf 0.1875 \ g/cm^3}}[/tex]
Step-by-step explanation:
Density can be found by dividing the mass by the volume.
[tex]\rho= \frac{m}{v}[/tex]
The mass of the cork is 3 grams and the volume is 16 cubic centimeters.
[tex]m= 3 \ g\\v= 16 \ cm^3[/tex]
Substitute the values into the formula.
[tex]\rho = \frac{3 \ g }{16 \ cm^3}[/tex]
Divide.
[tex]\rho=\frac {3}{16} \ g/cm^3[/tex]
[tex]\rho=0.1875 \ g/cm^3[/tex]
The density of the cork is 3/16 or 0.1875 grams per cubic centimeter.

Two years ago Juanita bought 2 shirts for $15 and last year she bought 4 shirts for $45. Assuming the prices will increase linearly, how much will 8 shirts cost Juanita this year?
Answer:
This year, Juanita will have to use $75.
Step-by-step explanation:
Because if 2 shirts is $15, 4 shirts will be $30. $45 is $15 more than $30, so the increase is $15. 2*4 is 8, so that will make it 15*4=60. 60+15=75.
answer this please !!!!!!
Answer:
C) 140
Step-by-step explanation:
We can see from the diagram that mMEF + mDEM = mDEF because they share the same lines.
Therefore:
69x + 2 + 34 = 2 + 86x
Now we can solve this equation.
First we can eliminate the +2 from each side as they will cancel:
69x + 34 = 86X
And then rearrange to solve for x:
34 + 69x - 69x = 86x - 69x
34 = 17x
34/17 = 17x/17
x = 2
Now that we have the value for x, we can substitute it into the original equation:
mMEF = 69(2) +2
mMEF = 138 + 2
mMEF = 140
Therefore the correct answer is C) 140.

Fran buys used DVDS. She pays 2.75 for each DVD she buys. She graphs a line to show the total amount (y) in dollars, she pays to buy x used DVDS which equation correctly describes Fran lines?
A) y= 2.75
B) y= 2.75x
C) y= x + 2.75
D y= 2.75x + 2.75
Answer:
B) y=2.75x
Step-by-step explanation:
2.75 is the amount the DVDs cost and x is the number of DVDs Fran buys. So it'll cost her 2.75 for every DVD she buys
The equation that correctly describes Fran lines is y = 2.75x
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the total amount for x used DVDs.
She pays 2.75 for each DVD she buys. Hence:
y = 2.75x
The equation that correctly describes Fran lines is y = 2.75x

7. The lifetime of a certain brand of tires is approximately normally distributed, with a
mean of 40,000 miles and a standard deviation of 2,500 miles under normal driving conditions.
Tire wear is greatly affected by road, weather and driver conditions along with proper
maintenance of the tires. A driver who aggressively accelerates or makes quick stops, for
example, will wear out a tire much more quickly. The brand carries a warranty of 33,000 miles
under normal driving conditions, i.e., the company will replace a tire if it wears out before this
mileage limit is reached.
Answer:
0.0025551
Step-by-step explanation:
Given that:
Mean (m) = 40000
Standard deviation (s) = 2500
P(x < 33,000) :
USing the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (33000 - 40000) / 2500 = - 2.8
p(Z < -2.8) = 0.0025551 ( Z probability calculator)
Probability of Tyre wagering out before mileage limit is reached = 0.0025551
If: x² - y² = 60 and x+y= 5√6, Then x-y=....
I need an explanation of the answer please...
Answer: 2√6
x² - y² can be factored as (x+y)(x-y), so we can write x² - y² = (x+y)(x-y). Plugging the values we already know for x² - y² and (x+y), we have 60 = 5√6 (x-y), so (x-y) = 60/(5√6) = 2√6.

Tom is going to turn little Quacker into roast duck! He goes to the grocery store to get some salt and pepper seasoning to his duck dinner. Salt costs .50 cents per scoop. Pepper cost .75 cents per scoop, and he wants to speand less that $5. He plans to bring home no more than 8 scoops of seasoning
Answer:
He can buy 3 scoops of salts and 4 scoops of pepper or 4 scoops of salts and 3 scoops of pepper spent maximum.
Step-by-step explanation:
Given that:
The cost of salt = 50 cents / scoop =$ 0.5 / scoop
The cost of pepper =75 cents / scoop = $ 0.75 / scoop
Let he buys x scoops of salt and y scoops of pepper.
As he plans to bring home no more than 8 scoops of seasoning, so
[tex]x+y\leq8\cdots(i)[/tex]
The total cost of x scoops of salt and y scoops of pepper = 0.5x+0.75y
As he wants to spend less than $5, so
[tex]0.5x+0.75y<5 \\\\ \Rightarrow 50x+75y<500 \\\\\Rightarrow 2x+3y <20\cdots(ii)[/tex]
Here, [tex]x\geq 0, y \geq 0[/tex] and x,y are counting numbers.
On plotting the graph of equations (ii) and (ii), the possible solution is the integral values in the shaded as shown in the figure.
The maximum possible integral values, for expances less than $5, are (x,y)=(3,4), (4,3).
Hence, he can buy 3 scoops of salts and 4 scoops of pepper or 4 scoops of salts and 3 scoops of pepper to spent maximum.
Egal loggers got away with 4 acres of trees at a reserve in central Mexico. That number represents a 97 percent decline from two years prior. How many acres of trees did the illegal loggers get away with two years prior? Round the answer to the nearest acre.
Answer: with 133.33 acres of trees
Step-by-step explanation:
4 acres of trees, is a 97% decrease of the previous amount.
This means that if the previous amount was X, then 4 acres is 3% (or 0.03 in decimal form) of X, or:
4 acres = 0.03*X
Now we can solve this for X as:
X = 4acres/0.03 = 133.33 acres
The illegal loggers got away with 133.33 acres of trees

5t - 3 (7t + 1) < 93
Step-by-step explanation:
5t-3(7t+1) < 93
Remove the parentheses
5t-21t-3 < 93
-16t < 93+3
-16t < 96
Divide both sides by 16
-t<96/16
-t<6
t > -6
Answer: The inequality t < 6 is the correct answer.
Step-by-step explanation:
5t - 3 (7t + 1) < 93 <--- This is the original equation.
5t + (7t + 1) - 3 < 93 <---- Use commutative property.
16t - 3 < 93 <--- Simplify
16t - 3 + 3 < 93 + 3 <---- Add 3 to both sides,
16t < 96 <--- Simplify and do addition.
[tex]\frac{16t}{16}[/tex] < [tex]\frac{96}{16}[/tex] <--- Divide both sides by 16.
t < 6 <--- is the answer to the inequality.
