First, let's remember how we calculate a percentage:
If we call the number "x", 4% is calculated by dividing x by 100 and then multiplying by 4:
[tex]\frac{x}{100}\times4[/tex]This can also be represented as follows:
[tex]\frac{4}{100}\times x[/tex]Thus, 4% of a number is 4/100 of that number. We can still simplify this result as follows:
[tex]\frac{4}{100}=\frac{1}{25}[/tex]We divide 4 by 4 and get 1, and also divide 100 by 4 and get 25.
Answer: 4% of a number is 1/25 of that number.

can anyone solve? 14 x 3 - 2 + 3
Answer:
43
Step-by-step explanation:
So, the key to solving this is PEMDAS, or parenthesis, exponents, multiplication/division from left to right, and addition/subtraction from left to right. So, you start off with 14x3, which is 42. So, you have 42-2+3. Next, you have to do 42-2, which is 40. Finally, you do 40+3, which is 43.
Answer:
43
Step-by-step explanation:
14 x 3 - 2 + 3
PEMDAS says multiply before adding or subtracting

[tex]\frac{4.5\times10^3}{3\times10^6}[/tex]We can rewrite the fraction as:
[tex]=\frac{4.5}{3}\times\frac{10^3}{10^6}[/tex]We then simplify and apply the division law of indices to obtain:
[tex]\begin{gathered} =1.5\times10^{3-6} \\ =1.5\times10^{-3} \end{gathered}[/tex]Note: When you have the same base of an exponent and the terms are being divided, we simply subtract the power of the numerator from that of the denominator.
Find the area and perimeter of a rhombus with a diagonals 15 in and 20 in
Given data:
The diagonals of rhombus d1 = 15 in and d2 = 20 in
The area of the rhombus,
[tex]\begin{gathered} A=\frac{1}{2}\times d1\times d2 \\ A=\frac{1}{2}\times15\times20 \\ A=150\text{ inches sq.} \end{gathered}[/tex]Now, to find the perimeter of rhombus we first find the side of rhombus.
The diagonal of the rhombus is considered as diameter, so the radius will be
d1 = r1 = 7.5
d2 = r2 = 10
So, by using the pythagorean theorem we find the side of the rhombus
[tex]\begin{gathered} h^2=(7.5)^2+(10)^2 \\ h^2=56.25+100 \\ h^2=156.25 \\ h=12.5 \end{gathered}[/tex]The perimeter of the rhombus is,
[tex]\begin{gathered} P=4\times side \\ P=4\times12.5 \\ P=50\text{ inches} \end{gathered}[/tex]Thus, the area is 150 in. sq. and perimeter is 50 in.

Replace x =-x in the function f(x) to find h(x).
[tex]f(-x)=(-x)^2-4(-x)+12.[/tex][tex]f(-x)=x^2+4x+12.[/tex]Replace f(-x)=y in the equation.

[tex]y=a(x-h)^2+k.[/tex]where a=1, h=-2, and k=8.
The point (h,k)=(-2,8) is the turning point.

The turning point of y=h(x) is (-2,8).

I need help with this problem
Answer:
y = x-13
Step-by-step explanation:
So this question asks for two numbers. Let's call them x and y.
Since we know that x is larger than y, and the difference between them is 13, x must be greater than y by 13. So, x = y + 13
x = y + 13 isn't what the question is asking for though, so we have to isolate y to make one side contain only x and numbers. To do that, subtract both sides by 13 to get:
x - 13 = y
rearrange:
y = x - 13

A packing carton has a square bottom 18 inches by 18 inches. If the capacity of the carton is 3cubic feet, how deep is the carton?
The packing carton has a square bottom with measures 18in x 18in and has a volume of V=3ft³
The volume of cubic prims can be calculated by multiplying its width by its length and height:
So the formula to calculate the volume is
[tex]V=w\cdot l\cdot h[/tex]If we know the width, length, and volume we can determine the height. First, write the formula for h, that is, divide the volume by the width and height:
[tex]h=\frac{V}{wl}[/tex]The units of the width and length are in inches and the volume is in cubic feet, to determine the height of the box, all units must be the same. To make the calculations easier I will pass the units from inches to feet.
The unit rate between inches and feet is the following:
[tex]1^{\doubleprime}=\frac{1}{12}ft[/tex]To express 18 inches in feet you have to multiply them by 1/12
[tex]18\cdot\frac{1}{12}=1.5[/tex]This means that the width and length of the box measure 1.5ft
Now we can determine the height of the box as follows:
w=l=1.5ft
V=3ft³
[tex]\begin{gathered} h=\frac{V}{wl} \\ h=\frac{3}{1.5\cdot1.5} \\ h=\frac{4}{3}ft \end{gathered}[/tex]The height of the box is 3/4ft, if you multiply it by 12 you can express the measure in inches:
[tex]\frac{3}{4}\cdot12=9[/tex]The box has a deph of 9 inches.

The expression is √3/2 (sin x) - (cos x)/2
Here we have
sin( x + 11π/6)
We have to express it in terms of sin(x) and cos(x)
sin ( 2π - π/6 + x)
sin ( 2π + ( x - π/6))
sin(2π + Ф ) = sin Ф
So
sin( x - π/ 6)
Formula :
sin(A -B) = sin A cos B - cos A sin B
sin( x - π/ 6)
sin x cos π/6 - cos x sin π/6
con π/6 = √3/2 and sin π/6 = 1/2
√3/2 sin x - 1/2 cos x

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
The first step must be to convert days to hours. A day is equivalent to the 24 hours.
1 day = 24 hours
24 x 7 = 168 hours
The second step must be to convert minutes to hours,
60 minutes = 1 hour
15 / 60 = 0.25 hours
Now, add up all the converted hours together;
Total hours = 168 hours + 3 hours + 0.25 hours

From that point, the boat’s crew measures the angle of elevation to the lighthouse’s beacon-light from that point to be 8^{\circ} ∘ . At some later time, the crew measures the angle of elevation from point BB to be 5^{\circ} ∘ . Find the distance from point AA to point BB. Round your answer to the nearest foot if necessary.
The angle of elevation reduces. The distance between points A and B is roughly 1,269.9 ft.
The distance between point A and the lighthouse is 968 feet.
The angle of elevation from point A to the lighthouse is 7 degrees.
Elevation angle from point B to the lighthouse = 3°
The distance between points A and B.
tan 7° = Height of the sea / 968 feet
tan(7°) 968 feet 118.86 feet = height to the lighthouse
We have from point B;
tan 3° = 118.86 / Horizontal distance from B to HL
Therefore;
Horizontal distance from LH to boat = 118.6 / tan 30° = 2237.9 = feet
Therefore;
D is the distance between A and B.
D = Horizontal distance between B and LH - Horizontal distance between A and LH
