Answer:
14.3%
Step-by-step explanation:
subtract 320 with 280 which is 40. divide 40 with 280 and multiply that will 100. You get 14.3%
Answer:
14.28 %
Step-by-step explanation:
cost price of an umbrella = 280
selling price of an umbrella = 320
profit% = SP - CP / CP *100%
=320 - 280/280 * 100
=40/280 * 100
=4000/280
=14.28

- Mariana debe tomar dos pastillas; una cada 6 horas y otra cada 9 horas. Si a cierta hora toma las dos pastillas juntas, ¿después de cuantas horas volverá a tomarlas simultáneamente?
Answers
Answer:
Mariana takes the two pills together after 18 hours.
Step-by-step explanation:
Mariana must take two pills; one every 6 hours and another every 9 hours.
She take two pills together. Let she takes the two pills together after t hours at the time when she take initially.
To find the time to take the two pills together, take the least common multiple of 6 and 9.
6 = 2 x 3
9 = 3 x 3
So, the least common multiple is 2 x 3 x 3 = 18
So, she takes the two pills together after 18 hours.

Gianna bought 6.2 pounds of berries. She used 4.8 pounds of the berries to make a pie. What equation can be used to find how many pounds of berries, b, Gianna has left over? A 6.2 + 4.8 = b
B b − 6.2 = 4.8
C 4.8 + b = 6.2
D b − 4.8 = 6.2
Answers
This is because the total amount of berries she bought was 6.2 pounds
She used 4.8 pounds of berries and is left with b amount of berries
If you add the amount of berries used (4.8) to the amount left (b) you will get 6.2 pounds of berries
So the equation you can use to find the amount of berries left is 4.8 + b = 6.2

A school cotains 357 boys and 323 girls if a student is chosen at random, what is the probability that it is a girl
Answers
Answer:
[tex]P(G)=0.475[/tex]
Step-by-step explanation:
From the question we are told that:
Number of boys[tex]N_b=357[/tex]
Number of girls [tex]N_g=323[/tex]
Total Number of students
[tex]N_t=N_b+N_g[/tex]
[tex]N_t=680[/tex]
Generally the equation for Probability of Choosing a Girl is mathematically given by
[tex]P(G)=\frac{N_g}{N_t}[/tex]
[tex]P(G)=\frac{323}{680}[/tex]
[tex]P(G)=0.475[/tex]
Find how many kilometers they traveled by
bike.
Enter the correct answer.
George and Carmen went on a bicycle
trip. They took a bus to their starting
point, and then biked the rest. They
traveled 325 kilometers in total, and
they biked 75 kilometers more than they
were bussed.

Let x = kilometers traveled by bike and
y = kilometers traveled by bus. Find how many kilometers they traveled by bike
Answers
Answer:
Step-by-step explanation:
Biking is x and bussing is y. We know that the total distance is 325. Thus, the first equation in this system is
x + y = 325 (which says that the km traveled by bike plus the km traveled by bus totaled 325 km).
We also know that the pair biked 75 km more than they rode, giving us the second equation in our system:
x = y + 75. Now we use simple substitution and plug y + 75 in for x in the first equation:
(y + 75) + y = 325 and
2y + 75 = 325 and
2y = 250 so
y = 125 km. They rode the bus for 125 km and biked for 325 - 125 which is 200. And the difference is 75 km, as it should be!

Element X is a radioactive isotope such that every 69 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 20 grams, how much of the element would remain after 30 years, to the nearest whole number?
Answers
Answer:
[tex]15\text{ grams}[/tex]
Step-by-step explanation:
Since the mass of the radioactive isotope is halved every 69 years, we want to multiply its initial mass by [tex]1/2[/tex] every 69 years.
We can model this using the following equation:
The remaining mass, [tex]f(x)[/tex], is equal to the initial mass multiplied by [tex]\frac{1}{2}^{(\frac{t}{69})}[/tex], where [tex]t[/tex] is the number of years that have passed from the initial mass. The reason why the exponent is [tex]\frac{t}{69}[/tex] is because we only want to half the mass every 69 years, so [tex]\frac{69}{69}=1[/tex] and [tex]\frac{1}{2}^1=\frac{1}{2}[/tex].
Thus, we have:
[tex]f(x)=20\cdot \frac{1}{2}^{(t/69)}[/tex]
Substituting [tex]t=30[/tex], we get:
[tex]f(x)=20\cdot \frac{1}{2}^{(30/69)}=20\cdot 0.73980522316=14.7961044632\approx \boxed{15\text{ grams}}[/tex]
The distance between the parallel lines x – 2y = 3 and 2x – 4y = 12 is

Answer:
???????????????????????
Step-by-step explanation:
sorry di ko po alam yung sagot pasensiya na po
Given :
Parallel lines are
x – 2y = 3 and 2x – 4y = 12
Step-by-step explanation:
Lets write the given lines in slope intercept form y=mx+b
[tex]x -2y = 3 \\-2y=-x+3\\Divide \; both \; sides \; by -2\\y=\frac{x}{2} -\frac{3}{2}[/tex]
From the above equation , y intercept of first line is [tex]\frac{-3}{2}[/tex]
Solve the second equation for y and find out y intercept
[tex]2x-4y=12\\-4y=-2x+12\\Divide \; by \; -4\\y=\frac{1}{2} x-3[/tex]
y intercept of second line is -3
To find the distance between parallel lines, we subtract the y intercepts
[tex]\frac{-3}{2} -(-3)=\frac{-3}{2} +\frac{6}{2} =\frac{3}{2} =1.5[/tex]
Answer:
The distance between the parallel lines = 1.5

feet, calculate the amount of floor left uncovered by the circular area rug in a
rectangular living room. Show all work.
Answers
The amount of floor left uncovered by the circular area rug is 160.36 ft².
What is the amount of floor left uncovered by the circular area rug?The first step is to determine the area of the rectangular room.
Area of the rectangular room = length x width
14 x 16 = 224 ft²
The second step is to determine the area of the circular rug.
area of the circular rug = πr²
= 22/7 x 4.5² = 63.64
Now, subtract the area of the rug from the area of the room:
Area left uncovered = 224 ft² - 63.64 = 160.36 ft²
