Isa finished 30% of his homework in 27 minutes. How many more minutes will it take Isa to complete his homework, assuming that he works at the same pace?
Answer:
90 Minutes
Step-by-step explanation:
If he took 27 minutes to do 30% of his homework, then we can reverse the operation to find the total amount
30% is the same as 0.3, therefore you divide 27 by 0.3 because the 100% is 1, so by dividing you'll get the 100%.
90 minutes
Step-by-step explanation:
So 27 = 30%
30% + 30% + 30% = 90%
27 + 27 + 27 = 81
30% ÷ 3 = 10%
27 ÷ 3 = 9
90% + 10% = 100%
81 + 9 = 90
I'm sorry if this is wrong I got kind of confused for a second. But I hope this at least helps.-FinnyA lampshade has a height of 12cm and upper and lower diameters of 10cm and 20cm A)what area of material is required to cover that curved surface of the frustum B)what is the volume of the frustum (Give both answers in terms of pie)
Answer:
[tex](a)\ Area = 195\pi[/tex]
[tex](b)\ Volume = 700\pi[/tex]
Step-by-step explanation:
Given
[tex]h = 12[/tex]
[tex]d_1 = 10[/tex] --- lower diameter
[tex]d_2 = 20[/tex] --- upper diameter
Solving (a): The curved surface area
This is calculated as:
[tex]Area = \pi l(r_1 + r_2)[/tex]
Where
[tex]r_1 = 0.5 * d_1 = 0.5 * 10 = 5[/tex] --- lower radius
[tex]r_2 = 0.5 * d_2 = 0.5 * 20 = 10[/tex] --- upper radius
And
[tex]l = \sqrt{h^2 + (r_1 - r_2)^2[/tex] ---- l represents the slant height of the frustrum
[tex]l = \sqrt{12^2 + (5 - 10)^2[/tex]
[tex]l = \sqrt{12^2 + (-5)^2[/tex]
[tex]l = \sqrt{144 + 25[/tex]
[tex]l = \sqrt{169[/tex]
[tex]l = 13[/tex]
So, we have:
[tex]Area = \pi l(r_1 + r_2)[/tex]
[tex]Area = \pi * 13(5 + 10)[/tex]
[tex]Area = \pi * 13(15)[/tex]
[tex]Area = 195\pi[/tex]
Solving (b): The volume
This is calculated as:
[tex]Volume = \frac{1}{3}\pi * h * (r_1^2 + r_2^2 + (r_1 * r_2))[/tex]
This gives:
[tex]Volume = \frac{1}{3}\pi * 12 * (5^2 + 10^2 + (5 * 10))[/tex]
[tex]Volume = \frac{1}{3}\pi * 12 * (25 + 100 + (50))[/tex]
[tex]Volume = \frac{1}{3}\pi * 12 * (175)[/tex]
[tex]Volume = \pi *4 * 175[/tex]
[tex]Volume = 700\pi[/tex]
Frozen motts sticks cost $.022 each. If there are 6 sticks in on order, what is the portion cost for an order of motts sticks?
Answer:
$ 1.32
Step-by-step explanation:
Given :-
Cost of each Mott's Stick = $0.22 .Now there are 6 sticks in an order . So the cost of six sticks will be ,
→ Cost = $ 0.22 × 6
→ Cost = $ 1.32
Hence the cost of an order of sticks is $ 1.32The table below shows the distribution of eye color and hair color for the 60 students in

The volume of prism for the given condition is 147 cm³.
What is volume of prism?A prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.
Here, Prism(Rectangle)
Length(L) = 3.5 cm.
Width(W) = 6 cm
Height (H) = 7 cm
Volume = Area of Rectangle x Height
Volume of Prism: V = L x W x H
V = 3.5 X 6 X 7
V = 147 cm³
Thus, The volume of prism for the given condition is 147 cm³.

What is a logarithmic function?The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = bx is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.
Using the first and last data points (4,1) and (600,6), we can set up a system of two equations in two unknowns:
ln(y) = ln(a) + b * x1
ln(y') = ln(a) + b * x2
where x = 4, y = 1, x' = 600, and y' = 6. Taking the difference between the two equations, we get:
ln(y'/y) = b * (x' - x)
Solving for b, we get:
b = (1/(x' - x)) * ln(y'/y)
Substituting the values, we get:
b = (1/(600-4)) * ln(6/1)
b = 0.071
To find ln(a), we can use either of the two equations with the known values of ln(y) and b. Using the first equation, we get:
ln(y) = ln(a) + b * x
Substituting the values, we get:
ln(1) = ln(a) + 0.071 * 4
ln(a) = -0.279
Now that we have the values of ln(a) and b, we can convert them back to the exponential equation:
ln(y) = -0.279 + 0.071 * x
y = e^(-0.279) * e^(0.071 * x)
y = 0.755 * e^(0.071 * x)
This is the exponential regression equation that fits the given data.

in a school ,the number of boys who play cricket is 3 times as much as a number of boys who play tennis. if 12 boys, who play cricket, play tennis instead, the number of boys who play each of these sports would be the same. find the number of boys who play tennis
Answer:
The number of boys who play tennis is 36.
Step-by-step explanation:
Let the number of boys who play tennis is x.
number of boys who play cricket = y
x = 3 y..... (1)
12 boys plays both cricket and tennis.
According to the question,
x - 12 = y + 1 2
3 y - 12 = y + 12
2 y = 24
y = 12
So, the number of boys who plays tennis is x = 3 x 12 = 36.

Brandon took a 50-question exam worth a total of 160 points. There were x two-point questions and y five-point questions.
Answer:
there were 20 two point questions =
there were 30 five point questions
Step-by-step explanation:
Brandon took a 50-question exam worth a total of 160 points. There were x two-point questions and y five-point questions. How many of each type of question were on the exam?
x + y = 50 eqn 1
2x + 5y = 160 eqn 2
this can be solved using simultaneous equation
multiply eqn 1 by 2
2x + 2y = 100 eqn 3
subtract eqn 3 from 2
3y = 60
y = 20
Substitute for y in eqn 1
x + 30 = 50
x = 20
