Jan wants to buy a book that is regularly $34.99. Find the cost when it is on sale at 10% off.
Answer:
$31.491
Step-by-step explanation:
Price of the book=$34.99
Sale given=10%
Price of the book after sale=34.99-{(10/100)*34.99}
=34.99-3.499
=34.990-3.499
=$31.491

What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
We have to given that;
The steps for deriving the Quadratic Formula are shown.
Now, From fifth step;
⇒ x² + bx/a + b²/4a² + ----- - c/a + b² / 4a²
Hence, By factor we get;
⇒ (x + b/2a) (x + b/2a) + ------ - c/a + b² / 4a²
So, The correct choice for the missing reason is,
⇒ Factor

Step-by-step explanation:
an employer pays three workers x,y,z a total amount of 6100 a month. x is paid 125% of the amount y is paid; which represent 80% of the amount z is paid. how much does x receive a month
Answer: 2178.57
Step-by-step explanation:
Given
The employer pays 6100 total money a month
Suppose z receives A amount
Amount paid to y is 80% of A i.e.
[tex]\Rightarrow y=0.8A[/tex]
Amount paid to x is 125% of y i.e.
[tex]\Rightarrow x=1.25y=1.25\times 0.8A=A[/tex]
The Sum of their total money must be 6100
[tex]\Rightarrow A+0.8A+A=6100\\\Rightarrow 2.8A=6100\\\Rightarrow A=2178.57[/tex]
Amount receive by x is 2178.57
is travelling to another country.
He flies for 7 hours at an average speed of 990 km/h on one plane.
He then flies for 6 hours 15 minutes at an average speed of 920 km/h on a second plane.
What is the total distance, in km, he travelled by plane?
Answer:
First time=7hours
First speed=990km/hour
First distance=first time×first speedD=(
S×T)
D=990km/hr×7hrs
D=6930km.
Second time=6&14min.
Second speed=920km/hr
Second distance=second speed×second time (D=s×t)
D=920km/hr×6&14min.
D=1500
Total distance=6930+1500
=8430

Step-by-step explanation:
After traveling 70 m in its dive, the submarine is at a depth of 25 m. What will the submarine’s depth be if it continues its dive for another 110 m? (NOTE: The total length of the dive is MORE than 110m!)
Answer:
Total Depth: 64.28m
Step-by-step explanation:
Assuming that the submarine is travelling at a constant rate, then we can use the information provided and apply a Rule of Three since it is basically a ratio problem. In this rule, you simply need to multiply the diagonal values of the ratio and divide by the last value to get the variable, which would be the depth after 110m
70min <=======> 25 m
110min <=======> x m
(110 * 25) / 70 = x
2750 / 70 = x
39.28 = x
We can see that at 110min the depth would be 39.28 m but since this is an additional period of time that the submarine travelled we need to add this distance to the initial 25 m to get the total depth of the submarine.
39.28m + 25m = 64.28m
A CD player is advertised at a price of $1200. It could be bought cash or by hire purchase. The table below shows the terms of payment.
A system has two components: A and B. The operating times until failure of the two components are independent and exponentially distributed random variables with parameter 2 for component A, and parameter 3 for component B. The system fails at the first component failure.
(a) - Read section 1.5.2 in the textbook.
(b) - What is the mean time to failure for component A and for component B
Answer:
[tex]E(x) = \frac{1}{2}[/tex] -- Component A
[tex]E(x) = \frac{1}{3}[/tex] -- Component B
Step-by-step explanation:
Given
Distribution = Exponential
[tex]\lambda = 2[/tex] --- Component A
[tex]\lambda = 3[/tex] --- Component B
Solving (a): The mean time of A
The mean of an exponential distribution is:
[tex]E(x) = \frac{1}{\lambda}[/tex]
We have:
[tex]\lambda = 2[/tex] --- Component A
[tex]E(x) = \frac{1}{2}[/tex]
Solving (b): The mean time of B
The mean of an exponential distribution is:
[tex]E(x) = \frac{1}{\lambda}[/tex]
We have:
[tex]\lambda = 3[/tex] --- Component B
[tex]E(x) = \frac{1}{3}[/tex]
Anthony bought a new rectangular table for his living room. The length of the table is 4 feet and the perimeter of the table is 14 feet. What is the width of the table?
Answer:
3 feet
Step-by-step explanation:
If the length is 4 feet, there are two lengths so you get 8
14-8= 6
Because there are two widths, you do 6 divided 2 and you get 3 feet
