Marco has $1.31 in his coin bank. He spends 87c to buy a pen. After he buys the pen,How much does he has left?
Answer: $0.44
Step-by-step explanation:
Since Marco has $1.31 in his coin bank and he spends 87c to buy a pen, the amount taht will be left with him after he buys the pen will be gotten by subtracting 87cents from $1.31.
Note that 100 cents = $1
Therefore, $1.31 will be = 100 × 1.31 = 131 cents.
Therefore, 131 cents - 87 cents = 44 cents or $0.44
He has $0.44 left

If r varies inversely as t and t= -6 when t =2, find r when t =-7.
plz give answer with steps
There was a little error in t= -6 when "t"=2, I think you meant when "r"= 2 when t =-6 so i corrected it before solving.
Answer:r= 7/3
Step-by-step explanation:
Step 1
r varies inversely as t ,written mathematically can be expressed as
r ∝ 1/t
Introducing the constant of proportionality. K we have
r ∝ 1/t
r=Kt
Step 2
Now when r= 2 when t =-6, we have that
r=Kt
2 = K -6,
k=2/ -6= -1/3
Step 3
Find r when t =-7
Using our equation,
r=Kt
r= -1/3 x-7
r= 7/3

On Tuesday the train journey took 7 hours and 20 minutes and began at 13 53. (i) At what time did the train journey end? [1] (ii) Tuesday's time of 7 hours 20 minutes was 10% more than Monday's journey time. How many minutes longer was Tuesday's journey?
i)It ended at 21:13
ii) 440*10/100
44 mins longer
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
110% = 440 minutes (Tuesday journey)
100% = 100/110 x 440
100% = 400 minutes (Monday journey)
Tuesday's journey took 40 minutes longer than Monday's journey.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
On Tuesday the train journey took 7 hours and 20 minutes and began at
13:53.
The time train journey ended.
= 13:53 + 7 hours + 20 minutes
= 13 hours + 53 minutes + 7 hours + 20 minutes
= 20 hours + 73 minutes
= 20 hours + 60 minutes + 13 minutes
= 20 hours + 1 hour + 13 minutes
= 21 hours + 13 minutes
This means,
= 21:13
The train ended the journey at 21:13
Tuesday's time of 7 hours and 20 minutes was 10% more than Monday's journey time.
This means,
Converting into minutes.
7 hours 20 minutes
= 60 x 7 + 20 minutes
= 420 minutes + 20 minutes
= 440 minutes
Monday's journey time.
110% = 440 minutes:
100% = 100/110 x 440
100% = 400 minutes
Thus,
Tuesday's journey took 40 minutes longer than Monday's journey.

Answer and Step-by-step explanation:
The answer would be D. 82%.
All we need to do is add together the amount that can swim.
We do this because all of the numbers added together equals 1, so the parts that are split off represent the percentages (in decimal form) of the total amount of people.
0.34 + 0.48 = 0.82.
Multiply by 100 and we get 82%.

He dimensions are tripled. The new surface area would be times larger than the original surface area.
Answer:
The new surface area would be 9 times larger than the original surface area.
Step-by-step explanation:
Here we do not know what was the original shape, but we will see that it does not matter.
Let's start with a square of side length L.
The original area of this square will be:
A = L^2
Now if each dimension is tripled, then all the sides of the square now will be equal to 3*L
Then the new area of the square is:
A' = (3*L)^2 = (3*L)*(3*L) = 9*L^2 = 9*A
So the new surface area is 9 times the original one.
Now, if the figure was a circle instead of a square?
For a circle of radius R, the area is:
A = pi*R^2
where pi = 3.14
Now if the dimensions of the circle are tripled, the new radius will be 3*R
Then the new area of the circle is:
A' = pi*(3*R)^2 = pi*9*R^2 = 9*(pi*R^2) = 9*A
Again, the new area is 9 times the original one.
If the figure is a triangle?
We know that for a triangle of base B and height H, the area is:
A = B*H/2
If we triple each measure, we will have a base 3*B and a height 3*H
Then the new area is:
A' = (3*B)*(3*H)/2 = (3*3)*(B*H/2) = 9*(B*H/2) = 9*A
Again, the new area is 9 times the original area.
So we can conclude that for any shape, the new area will be 9 times the original area.

1/3 divided by 6 with explanation!
Answer:
Step-by-step explanation:
In mathematics, every integer is a rational number, hence a whole number 6 can be written as 6/1. 1/3 ÷ 6 = 1/18 in fraction form. 1/3 ÷ 6 = 0.0556 in decimal form.
Answer:
1/18 or 18 is your answer.
Step-by-step explanation:
Since 1/3 is already in fraction form, we will now turn 6 into fraction form. Which is 1/6. Now we will put it into the equation 1/3 x 1/6 = 1/18. The fraction 1/18 can also be 18. Therefore, 18 or 1/18 is our answer.

Triangle ABC is isosceles with AB=CB. Circle M is inscribed in Triangle ABC such that it is tangent at points D, E, and F. If the length of BF is twice the length of CF and the perimeter of Triangle ABC is 32 inches, then determine the length of side BC in inches.
Answer:
The answer is "12 inches".
Step-by-step explanation:
Please find the image file of the graph.
We know [tex]AE = CF \ and \ EB = FB[/tex] so because the triangle is isosceles.
[tex]EB = 2x, FB = 2x,\ and \ CF = x[/tex] when [tex]AE[/tex] is called by [tex]x[/tex].
We know that [tex]AE = AD = x[/tex] since E and D are tangent points to a circle.
They have [tex]CD = CF = x[/tex] since D and F are tangent points only to circle.
Thus, if the perimeter is 32, the following is the result:
[tex]\to AE + EB + BF + FC + CD + DA = 32\\\\\to x + 2x + 2x + x + x + x = 32\\\\\to 8x = 32\\\\\to x = 4[/tex]
Therefore the length of [tex]BC = BF + FC = 2x + x = 3x = 12\ inches[/tex]

A cylindrical pipe is 25 ft long and has a volume of 900ft3 find it's approximate diameter to the nearest hundredth of a foot
Answer:
Diameter of the pipe ≈ 6.77 ft
Step-by-step explanation:
Volume of a cylinder = πr²h
Here, r = Radius of the cylindrical pipe
h = Length of the pipe
Volume of the pipe = 900 ft³
Length of the pipe = 25 ft
By substituting the given values in the formula,
900 = π(r)²(25)
r² = [tex]\frac{900}{25\pi}[/tex]
r = √11.459
r = 3.385
Diameter = 2(radius)
= 2(3.385)
= 6.77 ft
The diameter of the cylinderi is 6.77ft
Volume of a cylinderthe formula for calculating thevolume of a cylinder is given as
V = pi d²/4 × h
Given the following
V = 900ft³
h = 25ft
Substitute the given parameters
900 = 3.14 × d²/4 × 25
900 = 19.625d²
d² = 45.859
d = 6.77ft
Hence the diameter of the cylinderi is 6.77ft
