a book bought for $20 was sold at a loss of 15%. What is the selling price?
Step-by-step explanation:
SP=?
L%=15%
CP=$20
WE KNOW,
L= L%/100×CP
L= 15/100×20
L= 15/5
L= 3
NOW,
L = CP-SP
Or, 3 = 20 - SP
Or,SP= 20 -3
SP=RS 17
Answer:
book price= $2015% of $20= $3$20 -$3 = $17sold book price = $17a community center is trying to raise $1680 to purchase exercise equipment. the center is hoping to receive equal contributions from members of the community. write and algebraic expression to determine how much will be needed from each person if n people contribute. Then evaluate the expression for 10, 12, 14, or 16 people.
Lets find f(n) formula
[tex]\boxed{\sf f(n)=\dfrac{1680}{n}}[/tex]
Now
[tex]\\ \sf\longmapsto f(10)=\dfrac{1680}{10}=168[/tex]
[tex]\\ \sf\longmapsto f(12)=\dfrac{1680}{12}=140[/tex]
[tex]\\ \sf\longmapsto f(16)=\dfrac{1680}{16}=105[/tex]
[tex]\\ \sf\longmapsto f(14)=\dfrac{1680}{14}=120[/tex]

Question: If m<4 = 6x - 16 and m<8 = 2x + 4, then m<4 = _____
Pls show how you got it cause it’s confusing me a lot
Answer:
m<4 = 14
Step-by-step explanation:
m<4 = m<8
6x - 16 = 2x + 4
+16 +16
-----------------------
6x = 2x + 20
-2x -2x
-----------------------
4x = 20
/4 /4
-----------------------
x = 5
m<4 = 6x - 16
= 6(5) - 16
= 30 - 16
= 14
Thus, m<4 = 14
Answer:
m<4 = 14 --> final answer

What is 2/3 divided by 4 in the Simplest form?
Answer:
2/3 divided by 4 = .16
Step-by-step explanation:
This problem is pretty simple. Since we cannot divide this we can change the division sign into a multiplication, but to do this we need to also take the reciprocal of 2/3, which means we flip th number so it becomes 3/2. Now we can simply multiply. (1/4)*(3/2) which should give you 3/8

Answer:
Answer: (√3)/2
Step-by-step explanation:
[tex] \sin(35 \degree) \cos(25\degree) + \cos(35\degree) \sin(25\degree) \\ [/tex]
from trigonometry identities:
[tex] \sin(a + b) = \sin(a) \cos(b) + \cos(a) \sin(b) \\ [/tex]
a » 35°
b » 25°
Therefore;
[tex] = \sin(35\degree + 25\degree) \\ = \sin(60\degree) \\ \\ = \frac{ \sqrt{3} }{2} [/tex]

Every problem has a solution .Lets solve it .
Here given that
[tex]\\ \sf\longmapsto x=\dfrac{y}{5}[/tex]
Use cross multiplication[tex]\\ \sf\longmapsto y=5x\dots(1)[/tex]
Now
As its a triangle
[tex]\\ \sf\longmapsto 90+x+y=180[/tex]
Put y=5x[tex]\\ \sf\longmapsto 90+x+5x=180[/tex]
[tex]\\ \sf\longmapsto 6x+90=180[/tex]
[tex]\\ \sf\longmapsto 6x=180-90[/tex]
[tex]\\ \sf\longmapsto 6x=90[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{90}{6}[/tex]
[tex]\\ \sf\longmapsto x=15[/tex]
We need not to find y
See the marked angle and x are supplementary angles hence there sum will be 180
[tex]\\ \sf\longmapsto x+15=180[/tex]
[tex]\\ \sf\longmapsto x=180-15[/tex]
[tex]\\ \sf\longmapsto x=165[/tex]
The required angle is 165°.

A bottle contains 2 liters of water. The bottle leaks 80 milliliters of water every 3 minutes. Will the bottle be empty in an hour
Answer:
No
Step-by-step explanation:
2 liters = 2,000
80/3 = 26.6
the bottle leaks 26.6 milliliters in a min
26.6*60 = 1596
1596 / 1000 = 1.596 (to convert to liters)
the bottle will leak 1.596 an hour

Find the point on the y-axis that is 7 units from the point
(−7, −4).
(x, y) =
Answer:
-7,3
Step-by-step explanation:
The point on y - axis has coordinates = (0, -4)
We have a point whose coordinates are - P(-7, -4)
We have to find the point on the y-axis that is 7 units from the point.
What is the formula to find the distance between the two points on Cartesian plane ?The distance between two points -
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
According to the question, we have -
Coordinates of Point : P(-7, -4)
Since the other point is on y - axis, therefore its x - coordinate will be 0.
Let the point on y - axis have coordinates as - (0, k).
Using the formula discussed above -
7 = [tex]\sqrt {\left( {-7- 0} \right)^2 + \left( {-4 - k } \right)^2 }[/tex]
49 = [tex](-7)^{2}[/tex] + [tex](-4-k)^{2}[/tex]
[tex](-4-k)^{2}[/tex] = 0
[tex](k + 4)^{2}[/tex] = 0
Solve the quadratic equation, you will get -
k = -4
Hence, the point on y - axis has coordinates = (0, -4)
