Stuart bought a sweater on sale for 30% discount off the original price and another 25% off the discounted price . If the original price of the sweater was 600 , what was the final price of a sweater?.
Answer:
$301.50
Step-by-step explanation:
Given that:
Stuart brought a sweater on sale for 30% discount off.
Another 25% discount off
Original price = 600
To Find:
What was the final price of a sweater?
Solve:
$600 x 30% = $180
$600 - $180 = $402 (discounted price after 30% off)
$402 x 25% = $100.50
$402-100.50 = $301.50 (discounted price after 25% off & the final price)
Hence, the final price is $301.50

Under his cell phone plan, Ryan pays a flat cost of $68.50 per month and $5 per gigabyte. He wants to keep his bill at $92.50 per month. How many gigabytes of data can he use while staying within his budget?
Answer:
answer is 5.7
Step-by-step explanation:
Under Ryan's cell phone plan, he pays a flat cost of $68.50 per month and $5 per gigabyte. With a budget of $92.50, he can use up to 4 gigabytes of data.
Use the concept of subtraction defined as:
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that,
Ryan's flat cost per month is $68.50.
He pays $5 per gigabyte of data.
Ryan wants to keep his bill at $92.50 per month.
We know that Ryan pays a flat cost of $68.50 per month,
so subtract that from his budget:
$92.50 - $68.50 = $24.
Since Ryan pays $5 per gigabyte,
Divide the remaining budget ($24) by the cost per gigabyte ($5) to find out how many gigabytes he can use:
$24 / $5 = 4.8 gigabytes.
Therefore,
Ryan can use up to 4.8 gigabytes of data and still stay within his budget. Keep in mind that any fraction of a gigabyte will be rounded down,
So he can use a maximum of 4 gigabytes.

IDΚ, help, what's the value of x,
8x-2=-9+7x
Answer:
x = -7
Step-by-step explanation:
8x - 2 = -9 +7x
in this type of problem you have to get all the X's together on one side, and all the common variables together on the other.
8x = -7 + 7x (you add 2 to boths sides. The -2 and 2 clear out on the left side. The 2 and -9 added together forms -7 on the right)
x = -7 (you subtract 7x from both sides. The 7x and -7x cancel out on the right and you are left with on 1 x on the left side)
Answer:
x = -7Step-by-step explanation:
In this question we have given an equation that is 8x - 2 = -9 + 7x . And we're aksed to find the value of x .
Solution : -
[tex] \longmapsto \qquad \: 8x - 2 = -9 + 7x[/tex]
Step 1 : Adding 2 to both sides :
[tex] \longmapsto \qquad \:8x - \cancel{ 2} + \cancel{ 2} = - 9 + 7x+2[/tex]
On further calculations, we get :
[tex] \longmapsto \qquad \:8x =7x - 7[/tex]
Step 2 : Subtracting 7x on both sides :
[tex] \longmapsto \qquad \:8x - 7x = \cancel{7x} - 7 - \cancel{7x}[/tex]
On further calculations, we get :
[tex] \longmapsto \qquad \: \red{\underline{\boxed{ \frak{x = - 7}}}}[/tex]
Henceforth , value of x is - 7 .Verifying : -
Now ww are verifying our answer by substituting value of x in given equation . So ,
8x - 2 = -9 + 7x8 ( -7 ) - 2 = -9 + 7 ( -7 )-56 - 2 = -9 - 49-58 = -58L.H.S = R.H.SHence, Verified.Therefore, our answer is correct .
#Keep LearningBlake gives piano lessons in the evenings. He earns $20 for each piano lesson and has between 0 and 6 lessons each evening. The amount he earns in an evening depends on the number of lessons he gives. What is the range of this relation?
Answer:
The correct answer is B. {0, 20, 40, 60, 80, 100, 120}
Step-by-step explanation:
1. Let's check all the information given to answer this question correctly:
Rate of each piano lesson Blake gives = US$ 20
Blake can give between 0 and 6 lessons every evening
Earnings = Number of lessons * Rate of each lesson
2. What is the range of this relation?
Let's recall that the domain of a relation is the set of all values for which the relation is defined, and the range of the relation is the set of all values that the relation takes.
It means that the domain of the relation in this case is the number of lessons that Blake can give every evening:
{0, 1, 2, 3, 4, 5, 6}
And the range of this relation is the amount Blake earns in an evening depending on the number of lessons he gives:
{0, 20, 40, 60, 80, 100, 120}
The correct answer is B. {0, 20, 40, 60, 80, 100, 120}

The maximum load that a cylindrical column with a circular cross section
can hold varies directly as the fourth power of the diameter and
inversely as the square of the height. A 9 meter column 2 meters in
diameter will support 64 metric tons. How many metric tons can be
supported by a column 9 meters high and 3 meters in diameter?
Answer:
2396
Step-by-step explanation:
Let the diameter = d
Let the height = h
Formula
Metric Tons = k * d^4 / h^2
Solution
Metric Tons = 64
d = 2
h = 9
k = ?
(You can't do the second part by not using a ratio unless you put k in and solve for it)
64 = 2^4 k / 9^2
64 = 8 *k / 81
64 * 81 / 8 = k
5184 / 8 = k
k = 648
Solve for the second example
Metric Tons = d^4 * k / h^2
Metric Tons = ?
d = 5
h = 13
k = 648
Metric Tons = 5^4 * 648 / 13^2
Metric Tons = 625 * 648 / 169
Metric Tons = 2396 rounded.

What is the zero of
q(x) = -7/3x + 14?
Answer:
x = 6
Step-by-step explanation:
Solve for x:
-(7 x)/3 + 14 = 0
Put each term in -(7 x)/3 + 14 over the common denominator 3: -(7 x)/3 + 14 = -(7 x)/3 + 42/3:
(-(7 x)/3 + 42/3) = 0
-(7 x)/3 + 42/3 = (-7 x + 42)/3:
((-7 x + 42)/3) = 0
Multiply both sides of (-7 x + 42)/3 = 0 by 3:
(3 (-7 x + 42))/3 = 3×0
(3 (-7 x + 42))/3 = 3/3×(-7 x + 42) = -7 x + 42:
(-7 x + 42) = 3×0
0×3 = 0:
-7 x + 42 = 0
Subtract 42 from both sides:
(42 - 42) - 7 x = -42
42 - 42 = 0:
-7 x = -42
Divide both sides of -7 x = -42 by -7:
(-7 x)/(-7) = (-42)/(-7)
(-7)/(-7) = 1:
x = (-42)/(-7)
The gcd of 42 and -7 is 7, so (-42)/(-7) = (-(7×6))/(7 (-1)) = 7/7×(-6)/(-1) = (-6)/(-1):
x = (-6)/(-1)
(-6)/(-1) = (-1)/(-1)×6 = 6:
