If A varies directly as b and A=6, when b=1/3, find the equation that relates A and b.
Answer:
A = 18b
Step-by-step explanation:
A = kb
6 = k(⅓)
k = 6×3
k = 18
A = 18b
Answer:
a = 18b
Step-by-step explanation:
Given that a varies directly as b then the equation relating them is
a = kb ← k is the constant of variation
To find k use the condition that a = 6 when b = [tex]\frac{1}{3}[/tex] , thus
k = [tex]\frac{a}{b}[/tex] = [tex]\frac{6}{\frac{1}{3} }[/tex] = 18
a = 18b ← equation of variation
Colton has math and reading homework tonight. Colton can solve each math problem in 3 minutes and he can read each page in 1.5 minutes. The number of pages Colton read is twice the number of math problems he solved. and it took him 54 minutes to complete all of his homework. Determine the number of math problems Colton solved and the number of pages he read.
Answer:
12 math problems and 12 pages.
Step-by-step explanation:
Reading=1.5x
Soling math=3x
1.5x+3x=4.5 minutes. Add like terms together.
4.5x=54 minutes. Divide both sides by 4.5 to get x. So x=12 minutes.
1.5x=18 minutes. 3x=36 minutes
If 1 problem took him 3 minutes,what about 36 minutes??
Now divide 36 by 3. The answer is 12 problems.
If 1 page took 1.5 minutes, what about 18 minutes?? So divide 18 by 1.5 and you will get 12 pages .
Colton solved 9 math problems and read 18 pages.
Since Colton has math and reading homework tonight, and he can solve each math problem in 3 minutes and he can read each page in 1.5 minutes, and the number of pages Colton read is twice the number of math problems he solved, and it took him 54 minutes to complete all of his homework, to determine the number of math problems Colton solved and the number of pages he read, the following calculation must be performed:
3X + 2 x 1.5X = 54 3X + 3X = 54 6X = 54 X = 54/6 X = 9 3 x 9 + 1.5 x 9 x 2 = X 27 + 27 = X 54 = X

The division axiom states that both sides of an equation can be divided by the same number except 0, without changing the value of the equation
Answer:
This is true
Step-by-step explanation:
Take for example 10=5x, you would divide both sides by 5 without changing anything to the equation.
In a case like 5=0x, you can't divide both sides by 0, so the solution is undefined.
What is the perimeter and area of the shape given?
The perimeter of the given shape is 63.50 units and its area is 170.625 square units.
Step-by-step explanation:
Step 1:
First, we need to determine the distance between each of the points in the shape ABCDEFGH.
There are vertical lines and horizontal lines. The distances between vertical lines are found by calculating the difference in y values while for horizontal lines, the distances are found by calculating the difference between the x values.
Step 2:
Distance of line AB, 15 - 4.5 = 10.5,
Distance of line BC, 14 - 8 = 6,
Distance of line CD, 15 - 10 = 5,
Distance of line DE, 8 - 3 = 5,
Distance of line EF, 15 - 10 = 5,
Distance of line FG, 3 - (-2.25) = 5.25,
Distance of line GH, 15 - 4.5 = 10.5 and
Distance of line AH, 14 - (-2.25) = 16.25.
Step 3;
The area of ABCDEFGH = The area of ABGH - the area of CDEF.
The area of ABGH = Length × Width = AH × AB = 16.25 × 10.5 = 170.625 square units.
The area of CDEF = Length × Width = CD × DE = 5 × 5 = 25 square units.
The area of ABCDEFGH = 170.625 - 25 = 145.625 square units.
Step 4:
The perimeter of shape ABCDEFGH is just the sum of all its lines.
Perimeter of ABCDEFGH = 10.5 + 6 + 5 + 5 + 5 + 5.25 + 10.5 + 16.25 = 63.50 units.

Step-by-step explanation:
The sum of Rodney and his sister is 31 his sister is five years less than three times Rodney’s age what is the difference in age between Ronnie and his sister
Answer: The difference in their ages is 13.
Step-by-step explanation: We shall start by assigning letters to represent the age of each one of them, that is the unknown variables. So, we shall call Rodney’s age r, and his sister’s age we shall call t. If the sum of Rodney and his sister’s age is 31, then we can write this as an expression,
r + t = 31
Also three times Rodney’s age can be written as 3 times r, or simply put, 3r. So five years less than three times Rodney’s age is equal to 3r - 5. Hence his sister’s age is equal to 3r - 5, or simply put,
t = 3r - 5
What we now have is a pair of simultaneous equations
r + t = 31 ————(1)
t = 3r - 5 ————(2)
We shall use the substitution method here. From equation (2), t = 3r - 5. So we shall substitute for the value of t into equation (1).
r + t = 31 now becomes
r + 3r - 5 = 31
4r - 5 = 31
Add 5 to both sides of the equation
4r -5 + 5 = 31 + 5
4r = 36
Divide both sides of the equation by 4
r = 9.
That means Rodney’s age is 9.
If from equation (1) r + t = 31, we can now insert the value of r in order to find t.
r + t = 31
9 + t = 31
Subtract 9 from both sides of the equation
t = 22.
That means his sister’s age is 22 while Rodney’s age is 9.
Therefore the difference in age between Rodney and his sister is
22 - 9 which equals 13.
I need help with finding slope if anyone knows how because I don’t. Well, first I wanna know if my answer is correct. Pleasee
Answer:
the second option 2/5 and (3, -2)
Step-by-step explanation:
first for the slope you do rise over run. Meaning you find a point on the graph intersects "cleanly" as in (-2,-4) then find another point on the graph where the line intersects (3,-2). to find the slope you do the change in Y over the Change in X so what that means is that tou would take one Y value and subtract it from the otherY value (from the two points you just found) so in this example (-4)-(-2) which equals -2. then you do the same process for the X values (make sure to start with the same point) so (-2)-(3) which equals -5. then you divide (or leave as a fraction in this case) -2/-5 which simplifies to 2/5. so The slope is 2/5.

If u is inversely proportional to the square of v and u is 4/9 when v is 3, find u when v is 8
Answer:u=1/16
Step-by-step explanation:
u is inversely proportional to v^2
u=k× 1/v^2
u=k/v^2
When U=4/9 when v=3
4/9=k×1/3^2
4/9=k×1/9
4/9=k/9
Cross multiply
4×9=k×9
36=9k
Divide both sides by 9
36/9=9k/9
4=k
When v= 8, u=?
u=k/v^2
Recall k=4
u=4/8^2
u=4/64
u=1/16
What is the perimeter of an isosceles trapezoid whose base 1 is 39ft, base 2 is 27ft and height is 12ft
Step-by-step explanation:
Given one is an isosceles trapezoid. Hence its non-parallel sides are equal.
In order to find the Perimeter of trapezoid, we need to find the length of non-parallel sides
Length of non-parallel sides can be obtained using Pythagoras theorem as given below:
[tex]Length \: of \: non-parallel \: sides \\ = \sqrt{ {(diff. \: of \: bases)}^{2} + ({height)}^{2} } \\ = \sqrt{ {(39 - 27)}^{2} + {(12)}^{2} } \\ = \sqrt{ {12}^{2} + {12}^{2} } \\ = \sqrt{2 \times {12}^{2} } \\ = 12 \sqrt{2} \\ = 12 \times 1.414 \\ = 16.968 \\ = 16.97 \: ft \\ \\ perimeter \: of \: trapezoid \\= 39 + 27 + 2 \times 16.97 \\ = 66 + 33.94 \\ = 99.94 \: ft[/tex]

The intensity I of a light a distance x meters beneath the surface of a lake decreases exponentially. From the illustration, find the depth at which the intensity will be 60%. (Round your answer to the nearest meter.)
Answer:
6m is the answer
Step-by-step explanation: We have rounded numbers down and the correct answer is 6.25 =60% in the illustration it measures 70% =6m rounded up from 5.6
If we refer to reduction r to find meters and input m in the equation to find percent at 6m shown. We can re-arrange at point 6(6m)100 = 36 (6m)100=36/6 =6m 1/100 = 0.6. or 0.6/6 =1 To find ?r we can show 0.6 as 6r = 0.6 x 100 6r=10 6/10= 4r reduction etc.. 60% to work this out. Based on isolated data of only 6ft being shown and compare the relation with that 0-30%. and 0-40% in change of data with 6= 30% decrease = r = 6.25 as 6ft is r4 within reduction to 1dp. =3.2 which could be 3.2x 100=+30 etc rearrange and 3.2 x100 =32 +30 is 6.2
The requried depth at which the intensity will be 60% is 9 meters.
What is an exponential function?The function which is in format f(x) =aˣ where a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
Here,
Let the y be the intensity at distance x below the surface,
Now, exponential function representing the scenario is given as,
y = abˣ
Where,
a = 100%,
b = constant of variability.
Now,
for x = 0, y = 100%,
a = 100% - - - - (1)
And x = 6, y = 70%,
70 = ab⁶ - - - (2)
Dividing equation 1 by 2,
Gives b = 0.9423
Now,
y = 100(0.9423)ˣ
Put y = 60
60 = 100(0.9423)ˣ
x = 8.69
x≈ 9 meters
Thus, the requried depth at which the intensity will be 60% is 9 meters.

Melissa Sartini's gross pay is $52,000 a year. The state income tax rate is 3% of taxable wa
a married exemption for herself and her husband. Using Figure 2.3. how much is withheld a year for state
income tax?
After accounting for exemptions, Melissa's tax is calculated by multiplying her taxable income by the state income tax rate. Due to missing information regarding the value of exemptions, we've assumed Melissa's entire gross pay is taxable. Therefore, she pays $1,560 per year in state income tax.
Explanation:Based on the information presented in your question, we're to determine state income tax withholdings for an individual named Melissa Sartini. First, we need to subtract any allowable exemptions from Melissa's annual gross pay. In this question, the figures for the married exemptions are not provided so we'll have to assume that Melissa's taxable income is still $52,000.
To calculate the tax, we simply multiply her taxable income by the state income tax rate. The state income tax rate is given as 3%, so we convert 3% to a decimal (0.03) and multiply by $52,000. This gives us:
$52,000 * 0.03 = $1,560
Therefore Melissa has $1,560 withheld each year for state income tax.

Answer:
what do you need to do plz give the question
Step-by-step explanation:
Triangle A C D is shown. A line is drawn from point D to point B on side A C to form a right angle. Line A D is labeled s. The length of A B is 8, the length of B C is 5, and the length of B D is 15.
What is the value of s?
units
Answer: Line s = 17 units
Step-by-step explanation: Please refer to the attached diagram.
The triangle ACD is drawn and labeled such that line BD extends from point D and forms a right angle at point D. A careful observation shows that we now have two right angled triangles. One is DAB and the other is DCB. The unknown side ‘s’ lies on triangle DAB, hence we shall use the available dimensions in DAB. Line AD or a, is the hypotenuse (side facing the right angle). We can now apply the Pythagoras theorem since we have been given the other two sides.
The theorem states that,
AD^2 = DB^2 + AB^2
AD^2 = 15^2 + 8^2
AD^2 = 225 + 64
AD^2 = 289
Add the square root sign to both sides of the equation
AD =17.
Therefore, s measures 17 units
The line BD drawn perpendicular to side AC forms two right triangles with
the side s being of the hypotenuse side.
The value of s is 17Reasons:
The given parameters are presented ;
The given triangle = ΔACD
The points on the line BD are; Point B on side AC and point D
Line BD forms a right angle
Line AD = s
Length AB = 8
Length BC = 5
Line BD = 15
According to Pythagorean theorem, we have;
[tex]\overline{AD}[/tex]² = [tex]\overline{BD}[/tex]² + [tex]\overline{AB}[/tex]²
Which gives;
[tex]\overline{AD}[/tex]² = 15² + 8² = 289
[tex]\overline{AD}[/tex] = √289 = 17
Therefore;
[tex]\overline{AD}[/tex] = s = 17

Write the equation of a line in slope intercept form that contains the points (0,2) and (3,4)
Answer:
Step-by-step explanation:
Generally equation of a line is given as
y=mx+c
Then given the point (x, y)=(0,2)
Therefore x=0 and y=2
y=mx+c
2=m×0+c
2=0+c
Then, c=2
Then intercept is 2
Also given the point (x, y)=(3,4)
x=3 and y=4 and c=2
y=mx+c
4=m×3+2
4=3m+2
4-2=3m
2=3m
Then, m=2/3
Then, the slope of the graph is 2/3
y=mx+c
