The marked price of a radio set is 450000. A discount of 5% of the marked price is allowed. What is the selling price of the radio
Answer:
$427,500 dollars
Step-by-step explanation:
Given the following question:
Initial price = 450,000
5% discount
In order to find the answer, we simply find 5% of 450,000.
[tex]\frac{5\times450000}{100} =5\times450000=2250000\div100=22500[/tex]
[tex]450000-22500=427500[/tex]
[tex]r=427500[/tex]
The radio (after a 5% discount) costs "$427,500 dollars."

(b) Water flows into the tank at a rate of 30 litres per minute. Calculate the time taken to fill an empty tank. Give your answer to the whole minute. (1 litre = 1000 cm')
Answer:
Step-by-step explanation:
We need to know the volume of the tank. If the volume, X (in liters), is given in cm^3, convert the value to liters (1 liter = 1,000 cm^3). Then take the tank volume and divide by 30 liters/min:
X liters/(30 liters/min) = X/30 minutes

Given the two rectangles below. Find the area of the shaded region.
Answer:
75 units²
Step-by-step explanation:
Bigger rectangle: length * width
: 10 * 9
: 90 units²
smaller rectangle: length * width
: 3 * 5
: 15 units²
Shaded region = Bigger rectangle - smaller rectangle
= 90 units² - 15 units²

find x and y
y= x-5
y= -7x+11
Answer:
x = 2
y = -3
Step-by-step explanation:
make them equal to each other
x-5 = -7x + 11
8x = 16
x = 2
put 2 back in the equation to get y
y = 2 - 5
y = -3
Answer:
x = 2
y = -3
Step-by-step explanation:
Solve using substitution.
Substitute x-5 for y:
x - 5 = -7x + 11
Add 7x to both sides
8x - 5 = 11
Add 5 to both sides
8x = 16
Divide both sides by 8
x=2
Plug 2 back in for x to solve for y:
y = x - 5 = 2 - 5 = -3
(x, y)=(2, -3)
Which equation is equivalent to 16 Superscript 2 p Baseline = 32 Superscript p 3?.
The equation which is equivalent to 16 Superscript 2 p Baseline equal to 32 Superscript p 3 is,
[tex]2^{8p}=2^{5p+15}[/tex]
What is equivalent equation?Equivalent equation are the expression whose result is equal to the original expression, but the way of representation is different.
Given information-
The given equation in the problem is,
[tex]16^{2p}=32^{p+3}[/tex]
Write both the equation in the form of same base number as,
[tex](2^4)^{2p}=(2^5)^{p+3}[/tex]
The power of the power of a number can be written as product of both the numbers. Thus,
[tex](2)^{4\times2p}=(2)^{5\times(p+3)}\\2^{8P}=2^{5P+15}[/tex]
This is the required equation.
Now if the base is the same at both side of the expression, then the powers can be compared. Thus,
[tex]8p=5p+15[/tex]
Solve it further to find the value of p as,
[tex]8p-5p=15\\3p=15\\p=5[/tex]
Thus the equation which is equivalent to 16 Superscript 2 p Baseline equal to 32 Superscript p 3 is,
[tex]2^{8p}=2^{5p+15}[/tex]

another real estate agent sold a house for $315,000 last week if her commission is 1.25% of the selling price of the home find the amount of her commission. Please explain
Answer:
$ 3937.5
Step-by-step explanation:
First, we convert 1.25% into a decimal.
That would be .0125.
Now we multiply the decimal with the whole number to find our answer.
315000 × .0125 = 3937.5
Therefore, 3937.5 would be the amount of her commission.

A cube has eight vertices (corners) and twelve edges. A segment, such as x, which joins two vertices not joined by an edge is called a diagonal. Segment y is also a diagonal. How many diagonals does a cube have?
a. 6
b. 8
c. 12
d. 14
e. 16
Answer:
On each face, there are $2$ diagonals like $x$. There are $6$ faces on a cube. Thus, there are $2\times 6 = 12$ diagonals that are "x-like".
Every "y-like" diagonal must connect the bottom of the cube to the top of the cube. Thus, for each of the $4$ bottom vertices of the cube, there is a different "y-like" diagonal. So there are $4$ "y-like" diagonals.
This gives a total of $12 + 4 = 16$ diagonals on the cube, which is answer {E}
Step-by-step explanation:
There are $8$ vertices on a cube(A, B, C, D, E, F, G, H). If you pick one vertice, it will have 7 line segments associated with it, so you will have $\frac{8\cdot7}{2} = 28$ segments within the cube. The division by $2$ is necessary because you counted both the segment from $A$ to $B$ and the segment from $B$ to $A$.
But not all $28$ of these segments are diagonals. Some are edges. There are $4$ edges on the top, $4$ edges on the bottom, and $4$ edges that connect the top to the bottom. So there are $12$ edges total, meaning that there are $28 - 12 = 16$ segments that are not edges. All of these segments are diagonals, and thus the answer is $\boxed{E}$.
Ms. Lynch has 21 coins in nickels and dimes.
Their total value is $1.65. How many of each
coin does she have?
Answer:
Step-by-step explanation:So we know x + y = 21 and 5x +10y = 165 We line them up in columns x + y = 21 5x +10y = 165 To eliminate the x variable, I'll multiply every element in the 1st equation by -5. -5x + -5y = -105 5x + 10y = 165 Now we combine (add) the equations, which eliminates x altogether. 5y = 60 ... y = 12 From there, x + 12 = 21 ... x = 21-12 ... x = 9 You should double check. Do 9 nickles and 12 dimes equal $1.65? A very important thing to remember using this method is to do the same thing to each element in the equation that you change! I hope that helps.

The graph of function f (x) = 2ˣ - 3 is shown in figure.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The function is,
⇒ f (x) = 2ˣ - 3
Now, We get;
At x = 1;
⇒ f (x) = 2ˣ - 3
⇒ f (1) = 2 - 3 = - 1
At x = 2;
⇒ f (x) = 2ˣ - 3
⇒ f (2) = 2² - 3 = 1
Hence, The graph is passing through (1, - 1) and (2, 1).
Thus, The graph of function f (x) = 2ˣ - 3 is shown in figure.

Tlaloc pumped up 56 balls. He pumped up 5 dodge balls for every 9 other balls. Complete the table.
Total balls will be 14, dodge balls will be 20 and the number of other balls will be 36.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In another word, the equation is a set of variables that have been constructed.
In other words, an equation is a set of variables that are constrained through a situation or case.
The total ball will be the sum of dodge ball + other ball so it will be
5 + 9 = 14
The number of pumped up for a single ball
56/14 = 4
So the number of Tlaloc pumps of dodge ball will be 5 × 4 = 20.
Number of Tlaloc pump of other ball = 9 × 4 = 36.

Jade wants to buy a $200,000 term life insurance policy. She is 34 years old. Using the premium table, what is her annual premium for a 10 year policy? A 5-column table with 6 rows titled Annual Life Insurance Premium (per 1,000 dollars of face value). Column 1 is labeled age with entries 30, 31, 32, 33, 34, 35. Column 2 is labeled 5-year term male with entries 3. 98, 4. 08, 04. 19, 4. 30, 4. 42, 4. 54. Column 3 is labeled 5 year term female with entries 3. 66, 3. 76, 3. 87, 3. 98, 4. 10, 4. 22. Column 4 is labeled 10-year term male with entries 6. 06, 06. 13, 6. 30, 6. 38, 6. 45, 6. 53. Column 5 is labeled Female with entries 5. 72, 5. 79, 5. 85, 5. 93, 6. 01, 06. 9. A. $1,290 b. $1,202 c. $6,010 d. $820.
Premium rates are usually for premium per fixed face value. Jade's annual premium for a 10 year policy is given by Option b: $1,202
How to calculate the total annual premium for $x ?If its given that the annual premium is $p per $y face value, then we can calculate the annual premium for $1 face value and then use it to calculate annual premium for $x.
Using proportions, we get:
[tex]\rm \$y \: face \: value : \$p \: annual \: premiun\\\\\rm \$1 \: face \: value : \$\dfrac{p}{y} \: annual \: premiun\\\\\rm \$x\:face\: value : \$\dfrac{p \times x}{y} \: annual \: premiun\\[/tex]
For given case, from the tables, we see that for age 34, and 10 year life insurance for female gender , there is annual premium of 6.01 per $1000 face value.
Thus, we have p = 6.01, y = 1000
Since Jade wants to buy Life insurance for $200,000, thus, x = $200,000
Putting it in the above derived formula, we get:
[tex]\rm \$x\:face\: value : \$\dfrac{p \times x}{y} \: annual \: premium\\\\\rm \$200000\:face\: value : \$\dfrac{6.01 \times 200000}{1000} \: annual \: premium\\ = \$1202 \: annual \: premiun[/tex]

Answer:
42 students
40%
72 (end of number line)
Explanation:
How to find the percentage for the 28 students:
100% - 60% = 40%
Knowing that, we now know 28 = 40%. We need to figure out what 10% is equal so we can figure out what 60% is equal.
How to find 10%:
28 ÷ 4 = 7
10% = 7 students
How to find 60% of students:
10 · 6 = 60
7 · 6 = 42
With that information, we can find out the final sum.
40% + 60% = 100%
28 + 42 = 72.
