The proportional relationship between the number of inches a candle has burned away, b, at any time in hours, t, can be represented by the equation b = 0.25tb=0.25t. What is the constant of proportionality from the time in hours to the inches of candle that has burned away?
Answer:
k = 0.25t^2
Step-by-step explanation:
Given the equation :
b = 0.25t
b = number of inches that has burned away
t = time
From our knowledge of variation;
Since candle length will decrease with time ;
b α 1/ t
b = k/t
Where k is the proportionality constant
Comparing the equation :
b = 0.25t
k/t = 0.25t
k = 0.25t^2
Cameron needs to order some new supplies for the restaurant where he works. The
restaurant needs at least 598 spoons. There are currently 194 spoons. If each set on
sale contains 8 spoons, write and solve an inequality which can be used to determine
x, the number of sets of spoons Cameron could buy for the restaurant to have enough
spoons.
Answer:
Inequality: 8x+194_>598
Answer:x_>50.2
Step-by-step explanation:
I have delta math! I risked getting the answer wrong for this question lol. But this is correct just!
404 spoons are required for the restaurant for the fill needs.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Let's say the number of sets required = x
Then,
8x will be the total number of spoons.
So,
8x + 194 ≥ 598
8x ≥ 404
x ≥ 50.5
A number of spoon required = 50.5 × 8 = 404 spoons.
Hence "404 spoons are required for the restaurant for the fill needs".

Can somebody please help?
Answer:
A. Juan wins the race
B. At about 7 minutes J(t )= A(t)
C. 2 minutes
Step-by-step explanation:
A. Juan wins the race. This is because she covers the distance in a shorter time interval than Antonio
B. At about 7 minutes J(t )= A(t). to get this, just look at the point that the two curves intersect on the graph, and trace it down to the time axis to read off the time.
C. J(t) is greater than A(t) with about 2 minutes. To get this, we just subtract the time Juan arrived at the finish line from the time Antonio arrived, this is = 15 -13 = 2 minutes
Select all the equations for which y = 9 when x = -1.
The coordinate of centroid of a triangle whose vertices are (1,3,-2), (4,5,0), (6,3,9) is = ……………….
Answer:
[tex]C = (\frac{11}{3},\frac{11}{3},\frac{7}{3})[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1,z_1) = (1,3,-2)[/tex]
[tex](x_2,y_2,z_2) = (4,5,0)[/tex]
[tex](x_3,y_3,z_3) = (6,3,9)[/tex]
Required
Determine the coordinates of the centroid
Represent the coordinates with C.
C is calculated as follows:
[tex]C = (\frac{1}{3}(x_1+x_2+x_3),\frac{1}{3}(y_1+y_2+y_3),\frac{1}{3}(z_1+z_2+z_3}))[/tex]
Substitute values of x and y in the given equation
[tex]C = (\frac{1}{3}(1+4+6),\frac{1}{3}(3+5+3),\frac{1}{3}(-2+0+9}))[/tex]
[tex]C = (\frac{1}{3}(11),\frac{1}{3}(11),\frac{1}{3}(7}))[/tex]
[tex]C = (\frac{11}{3},\frac{11}{3},\frac{7}{3})[/tex]
The above is the coordinate of the centroid

Jason rowed 1/3 of a mile down the river.Jane rowed 2/6 of a mile down the river. Jude rowed 2/9 of a mile down the river.What is the total distance that jason Jane jude rowed down the river in total?
Answer:
8 / 9 miles
Step-by-step explanation:
Given that:
Jason's distance = 1/3 mile
Jane's distance = 2/6 miles
Jude's distance = 2/9 miles
The total miles rowed down the river by all 3 :
(1/3 + 2/6 + 2/9) miles
The L. C. M of the denominator (3, 6, 9) = 18
(6 + 6 + 4) / 18
16 / 18 miles
8 / 9 miles

We know that 15 elves represent the 20% of the total.
Since 20% is one-fifth, the total number of elves is

which yields
[tex]x=\dfrac{1500}{20}=75[/tex]

As we know that
Diagonal of square = √2 ( side of square )So , we need to find side of square first
Using area of square = Side²
➩ 144 = S²
➩ S = √144
➩ Side = 12 cm
Now ,
➨ Diagonal = √2 ( 12 )
➨ Diagonal of square = 12√2

The shape is composed of squares and quarter circles. Select all the expressions that represent its perimeter. (Select all that apply.) 42+14 7+7+7+7+7+7+3.5+3.5+3.5+3.5 91+14 147+49 7+7+7+7+7+7+7+7+7+7
Answer:
91+14π
Step-by-step explanation:
The question is incomplete. Find the complete question attached.
From the diagram shown;
It contains 4 quarter circles which is equal to a circle.
Perimeter of a circle = 2πr
r is the radius = length of one side of the square =7
Perimeter of the circle = 2πr
Perimeter of the circle = 2π(7)
Perimeter of the 4 quarter circles = 14π
Also in the diagram, there are 13 sides of the square present.
Perimeter of the squares = 13×length of one side of the square (Sum of all the sides)
Perimeter of the squares = 13×7 =91
Perimeter of the figure = Perimeter of the 4 quarter circles + Perimeter of the squares
Perimeter of the figure = 91+14π

E. 12 i
Given:
Consider the expression is [tex]\sqrt{-12}[/tex].
To find:
The value of given expression.
Solution:
We have,
[tex]\sqrt{-12}[/tex]
It can be written as
[tex]\sqrt{-12}=\sqrt{-1\times 12}[/tex]
[tex]\sqrt{-12}=\sqrt{-1}\times \sqrt{12}[/tex] [tex][\because \sqrt{ab}=\sqrt{a}\sqrt{b}][/tex]
[tex]\sqrt{-12}=i\times \sqrt{12}[/tex] [tex][\because \sqrt{-1}=i][/tex]
[tex]\sqrt{-12}=\sqrt{12}i[/tex]
Therefore, the value of given expression is [tex]\sqrt{12}i[/tex].

Which statement best represents the equation below 10+(-10) =0
Answer:
im not sure if this is the answer you wanted hope it helped though
Step-by-step explanation:
Applying the BODMAS rule where B=Brackets ,O=of,D=Division,M=multiplication,
A=Addition,S =subtraction
For any equation in which multiple operation is to be done its depends on the preference of the operation to be performed.
The preference followed is BODMAS
In the above question first multiplication will be performed first and then the addition is performed.
10+10*0+10

Answer:
D. a car goes 7 feet and then reversed 7 feet.
Step-by-step explanation:
The statement above can be set up in a simple equation.
7 - 7 = 0
This can best represent the equation 10 + (-10) = 0, because they both end up with the same result.
10 + (-10) = 10 - 10 = 0
