8 taps can fill a tank in 27 minutes.
So,
1 tap can fill the same tank in time = 27 × 8 = 218 minutes
Therefore, 6 remaining taps can fill the same tank = 216/6
= 36 minutes
The remaining 6 taps will take 36 minutes to fill the same tank.

You are considering buying a 30-year U.S. Treasury bond but are nervous about the effect on bond price if the yield to maturity on the bond increases. The bond has a 3% coupon rate and pays coupons semi-annually. The duration is 19 years. Suppose that interest rates on this bond rise by 0.9%. Calculate the corresponding percentage change in the price of the bond using the approximation method based on bond duration.
Answer:
The corresponding change in bond price = 17.1%
Step-by-step explanation:
In this question, we are interested in calculating the percentage change in the bond price using the approximation method based on bond duration;
Mathematically;
% change in bond price = Duration * Change in yield
From the question;
Duration = 19 years
Change in yield = 0.9%
Thus;
% change in bond price = 19 * 0.9% = 17.1%
The ages of three siblings combined is 27. The oldest is twice the age of the youngest. The middle child s three years older than the youngest. Write and solve an equation to find the ages of each sibling.
Answer:
The ages of the children are 6, 9 and 12.
Explanation:
Let x= the age of the youngest child.
If the oldest child is twice the age of the youngest, the age of the oldest child is twice x or 2x.
If the middle child is 3 years older than the youngest, the age of the middle child is x+3.
If the sum of their ages is 27, then
x+2x+x+3=27aaa(Combine like terms)
4x+3=27aaa
aa−3a−3aaa(Subtract 3 from both sides)
4x=24
4x4=24aaa(Divide both sides by 4)
Answer:
6, 9 & 12
Step-by-step explanation:
let x represent the age of the youngest kid
if the oldest kid is twice the age of the youngest, then it would be 2x
if the middle kid is 3 years older than the youngest, let this be x+3
if their ages in total is 27, then the equation is
x+2x+x+3=27
combine like terms first
4x+3=27
subtract 3 from both sides
4x=24
divide both sides by 4
you get 6. The youngest kid is 6.
For the oldest kid, the equation is 2x=2 times 6=12
the age of the middle child, equation is (x+3)=6+3=9

The correct statements are third "Point D represents a number less than the number Point C represents", and fifth "Point E represents the smallest number of all the numbers represented by points".
Given information:
The number line shows 6 points A, B, C, D, E, and F.
The sequence of numbers from left to right is E, B, D, C, A, and F.
In the number line, a point or number on the right is bigger than the point or number on the left.
From this, we can conclude that:
Point C is on the left of point F. So, point C is less than point F. The first statement is wrong.All the points are on the different locations on the number line. So, all the points represent different numbers. The second statement is also wrong.Point D is on the left of point C. So, the number represented by point D is less than the number represented by point C. The third statement is correct.Point F is on the rightmost location. So, it is the greatest number. The fourth statement is wrong.Point E is on the leftmost location. So, the number represented by point E is the smallest among the given 6 points. The fifth statement is correct.Therefore, the correct statements are third "Point D represents a number less than the number Point C represents", and fifth "Point E represents the smallest number of all the numbers represented by points".

If the area of a square is 32 square feet, estimate the length of each side of the square to the nearest whole number.
Answer:
the answer is actually 6
Step-by-step explanation:
The length of each side of the square to the nearest whole number is 6 feet.
Given that, the area of a square is 32 square feet.
We need to estimate the length of each side of the square to the nearest whole number.
What is the area of a square?A square is a closed two-dimensional shape with four equal sides and four equal angles. The four sides of the square form the four angles at the vertices. The sum of the total length of the sides of a square is its perimeter, and the total space occupied by the shape is the area of the square. The formula to find the area of a square =a², where a=side of a square.

A natural food store makes its own brand of trail mix out of dried apples, raisins, and peanuts. One pound of
the mixture costs $3.18. It contains twice as much peanuts by weight as apples. One pound of dried apples costs $4.48, a pound of raisins $2.40, and a pound of peanuts $3.44. How many ounces of each ingredient are contained in 1 pound of the trail mix?
Answer:
50.88
Step-by-step explanation:
dried apples,raisins and peanuts. One pound of the mixture is $3.18
it contains twice as much peanuts by weight than apples.
:
One pound of dried apples cost $4.48, a pound of raisins cost $2.40 and
a pound of peanuts is $ 3.44.
:
How many ounces of each ingredient are contained in one pound of the trail mix?
:
Here it is, step-by-step
:
Let a = no. of oz of apples
Let r = no. of oz of raisins
Let p = no. of oz of peanuts
:
The equation:
4.48a + 2.40r + 3.44p = 3.18(16)
:
It says p = 2a, substitute 2a for p
4.48a + 2.40r + 3.44(2a) = 3.18(16)
:
4.48a + 2.40r + 6.88a = 50.88
:
4.48a + 6.88a + 2.40r = 50.88
:
11.36a + 2.40r = 50.88
:
At this point we can say: r = (16-3a), a represents apples & peanuts here.
Substitute (16-3a) for r, solve for a;
11.36a + 2.40(16-3a) = 50.88
:
11.36a + 38.40 - 7.2a = 50.88
:
11.36a - 7.2a = 50.88 - 38.40
:
4.16a = 12.48
a = 12.48%2F4.16
a = 3 oz dried apples
then
P = 2(3)
P = 6 oz of peanuts
:
Find r:
r = 16 - 3 - 6
r = 7 oz of raisins
;
:
Check these values for a, r, p in the cost equation
4.48(3) + 2.40(7) + 3.44(6) = 3.18(16)
13.44 + 16.8 + 20.64 = 50.88; confirms our solutions
3 ounce of dried apples, 7 ounce of raisins and 6 ounce of peanuts are contained in 1 pound of the trail mix
What is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
Given:
Dried apples, raisins and peanuts.
One pound of the mixture is $3.18
it contains twice as much peanuts by weight than apples.
One pound of dried apples cost = $4.48,
raisins cost = $2.40
peanuts cost = $ 3.44.
Let x be number of oz of apples
Let y be number of oz of raisins
Let z be number of oz of peanuts
So, the equation can be written as
4.48x + 2.40y + 3.44z = 3.18(16)
As, z = 2x,
4.48x + 2.40y + 3.44(2x) = 3.18(16)
4.48x + 2.40y + 6.88x = 50.88
4.48x + 6.88x + 2.40y = 50.88
11.36x + 2.40y = 50.88
Also, y= (16-3a)
11.36x + 2.40(16-3x) = 50.88
11.36x + 38.40 - 7.2x= 50.88
11.36x - 7.2x = 50.88 - 38.40
4.16x = 12.48
x = 12.48 / 4.16
x = 3
and, z = 2(3)
z = 6
Similarly, y = 16 - 3 - 6
y = 7
Hence, 3 ounce of dried apples, 7 ounce of raisins and 6 ounce of peanuts.

Step-by-step explanation:
The two angles [tex](11x+5)[/tex] and [tex](5x-1)[/tex] are supplementary angles, meaning that their degrees add up to 180°. To find the value of [tex]x[/tex], we can use the following equation:

Two points,L and N are 160 m apart. M lies on the straight line joining L and N. An object travels from L to M at an average speed of 10 m/s in 6 seconds and then from M to N at an average speed of 25 m/s. Find the average speed of the object for it's entire journey from L to N.
Answer:
16m/sStep-by-step explanation:
If the object travels from L to M at an average speed of 10 m/s in 6 seconds, we can get the distance LM using the formula;
Speed = Distance/Time
Distance = Speed * Time
Distance = 10 * 6
Distance = 60m
Hence LM = 60m
Since LN = LM + MN
160 = 60 + MN
MN = 160-60
MN = 100m
If the object moves from M to N at an average speed of 25 m/s througj a distance od 100m, the time taken will be expressed as;
Time = distance/speed
Time = 100/25
Time = 4secs
Total time taken to move from L to N is 6secs + 4secs = 10secs
The average speed of the object for it's entire journey from L to N will be:
Average speed = Distance LN/10
Average speed for the entire journey = 160/10 = 16m/s
Hence the average speed of the object for it's entire journey from L to N is 16m/s
