Correct Questions:
The correct question has a diagram attached to it which has dimensions of the bedroom floor available which are 15 by 18 feet.
Answer:
Answer is 540 $
Step-by-step explanation:
We will first find the area of the room
Area = Length x Width
Area = 15 x 18 = 270 sq feet
She needs 270 square feet of carpet.
one square feet costs 2 $
so, total cost of carpet = 270 x 2 = 540 $

Carol has 88cm of string and cuts it in the ratio 5 : 6. How much longer is the
longest piece compared to the shortest piece
Given:
Carol has 88cm of string and cuts it in the ratio 5 : 6.
To find:
How much longer is the longest piece compared to the shortest piece.
Solution:
Let the lengths of two pieces of string are 5x and 6x. Then,
[tex]5x+6x=88[/tex]
[tex]11x=88[/tex]
[tex]x=\dfrac{88}{11}[/tex]
[tex]x=8[/tex]
Now, the lengths of pieces are:
[tex]5x=5(8)[/tex]
[tex]5x=40[/tex]
And,
[tex]6x=6(8)[/tex]
[tex]6x=48[/tex]
The difference between the longer piece and shorter piece is:
[tex]48-40=8[/tex]
Therefore, the longer piece is 8 m longer than the shorter piece.
How much commission would a salesperson ear for selling a car that costs $29,389? He receives 16% commission on each sale.
Answer:
Commission on car = $4,702.24
Step-by-step explanation:
Given:
Sales price of car = $29,389
Commission on sale of car = 16% = 0.16
Find:
Commission on car
Computation:
Commission on car = Sales price of car x Commission on sale of car
Commission on car = 29,389 x 16%
Commission on car = 29,389 X 0.16
Commission on car = $4,702.24
Solve the following system of equations using Substitution, showing all work.
2x+y=9
3x−2y=17
Answer:
(x,y)=(5,-1)
Step-by-step explanation:
1. 2x+y=9 ---> y=9-2x
2. Substitute y=9-2x into 3x-2y=17 ---> 3x-2(9-2x)=17 ---> 3x-18+4x=17 --> 7x=35 ---> x=5.
3. Substitute x=5 into 2x+y=9 ---> 2*5+y=9 ---> y=9-10 ---> y= -1
A $100 tablet is marked up by 10% and then the new price is marked down by 10%. What is the final price?
Answer:
$99
Step-by-step explanation:
So the initial price of the tablet was $100. It was marked up by 10% and then marked down by 10%. We are asked to find the final price.
To find the final price, lets first find the price after the tablet price was marked up by 10%. This means that the tablet price increased by 10%. To find the price, we can add 10% of the new original price (or 10% times $100) original price ($100):
$100 + ($100 × 0.1) = $100 + $10 = $110
We could have also multiplied $100 by 1.1 (or 1 + 10%) to find the new price.
So now we know that the new price after the tablet is marked up by 10% is $110. Now, to find the final price, we have to find the price after the new price is marked down by 10%. We can do this by taking the new price ($110) and subtracting 10% of the new price (or 10% times $110):
$110 - ($110 × 0.1) = $110 - $11 = $99
So the final price of the tablet would be $99.

A diver found a school of fish 85 feet below the surface of the ocean. He found coral 95 feet deeper than the fish. How many feet deep from the surface was the coral?
Answer:
180 feet
Step-by-step explanation:
85+95=180 because depth + depth.
The total deep 180 feet from the surface was the coral.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that diver found the school of fish 85 feet below the surface of the ocean. Which he found coral 95 feet deeper than the fish.
The total deep from the surface was the coral.
Therefore, it could be;
depth + depth.
85 + 95 = 180
Hence, the total deep 180 feet from the surface was the coral.

Which is the solution to the system 3x+y=8 and 7x−4y=25
Answer:
(3, - 1 )
Step-by-step explanation:
Given the 2 equations
3x + y = 8 → (1)
7x - 4y = 25 → (2)
Multiplying (1) by 4 and adding to (2) will eliminate the y- term
12x + 4y = 32 → (3)
Add (2) and (3) term by term to eliminate y
19x + 0 = 57
19x = 57 ( divide both sides by 19 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (1)
3(3) + y = 8
9 + y = 8 ( subtract 9 from both sides )
y = - 1
solution is (3, - 1 )

If a fair die is rolled twice and two numbers X1=result of the first roll and X2=result of the second roll are obtained. Given that X1+X2=7, what is the probability that X1 =4 or X2 =4
Answer:
P = 2/3 = 0.67
Step-by-step explanation:
Assuming that X1 + X2 = 7
The total number of outcomes such that X1 + X2 = 7 are:
X1 = 3, X2 = 4
X1 = 4, X2 = 3
X1 = 1, X2 = 6
X1 = 6, X2 = 1
X1 = 2, X2 = 5
X1 = 5, X2 = 2
So there are 6 total outcomes such that X1 + X2 = 7
Now, the probability that X1 = 4 is equal to the quotient between the number of outcomes where X1 = 4 (only one outcome) and the total number of outcomes (6)
Then:
p = 1/6
And the probability that X2 = 4 is calculated in the same way, then the probability is:
q = 1/6
Now, the probability that X1 = 4 or X2 = 4 is the sum of both probabilities we've found above, then:
P = p + q = 1/6 + 1/6 = 2/6 = 2/3 = 0.67

Water is filling a cylindrical water tank. As it is filled the radius of the tank expands at 0.2cm/s and the height decreases at the rate of 0.5cm/s. Find the rate at which the volume of the tank is changing at the instant the radius equals 1.8cm and height equals 65 cm. What is the volume of water at this point? Show all working. Volume, V, of the cylinder is given by V = ϖr2h.
Recall that V is a function of both r (radius of the cylinder) and h (the height of the cylinder). This is a partial differentiation problem. The volume is also changing with time.
Answer:
141.94 cm³/s
Step-by-step explanation:
Since the volume of the tank V = πr²h, and both the height and radius of the tank change with time, we find the rate of change of the volume with time, dV/dt from
dV/dt = dV//dr × dr/dt + dV/dh × dh/dt
where dV/dr = 2πrh, dr/dt = + 0.2 cm/s (since the radius of the tank expands), dV/dh = πr² and dh/dt = -0.5 cm/s (since the height of the tank decreases)
So,
dV/dt = dV/dr × dr/dt + dV/dh × dh/dt
dV/dt = 2πrh × + 0.2 cm/s + πr² × -0.5 cm/s
dV/dt = 0.4πrh cm/s - 0.5πr² cm/s
dV/dt = πr(0.4h - 0.5r) cm/s
We now find the rate at which the volume is changing when r = 1.8 cm and h = 65 cm.
So,
dV/dt = π(1.8 cm)(0.4 × 65 cm - 0.5 × 1.8 cm) cm/s
dV/dt = π(1.8 cm)(26 cm - 0.9 cm) cm/s
dV/dt = π(1.8 cm)(25.1 cm) cm/s
dV/dt = π(45.18 cm²) cm/s
dV/dt = 141.94 cm³/s
