At a hardware store, a tool set normally costs $80. During a sale this week, the tool set costs $12 less than usual. What percentage of the usual price is the saving? Explain or show your reasoning.

Answers

Answer 1

Original cost is $80.
Original cost is denoted by 100%

$80 represent 100%
$1 represent 100 ÷ 80 = 1.25%

Saving is $12
$12 represent 1.25 x 12 = 15%

So $12 represent 15%

According to the Bohr model, the radius of a hydrogen atom is approximately 5.29 × 10/-11 meters. What is this measurement written in standard form?
A. 0.00000000529 meters
B. 0.00000000000529 meters
C. 0.0000000000529 meters
D. 0.000000000529 meters

Answers

the answer is C, 0.0000000000529 because you move the decimal over as many places as the power says. For example, it says 10 to the -11th power so you move the decimal over 11 places to the left.

The measurement 5.29 × 10⁻¹¹ meters written in the standard form is option C, 0.0000000000529 meters.

Given that:

According to the Bohr model, the radius of a hydrogen atom is approximately 5.29 × 10⁻¹¹ meters.

It is required to write this number in scientific notation in the standard form.

Here the power of the 10 is negative.

So, the decimal point has to be shifted to the left.

Now, since the number to the power is 11, the decimal points have to be shifted 11 points to the left.

After shifting 1 point, the number is 0.529 × 10⁻¹⁰.

After shifting two points, the number is 0.0529 × 10⁻⁹.

In this way,

The number will have 10 zeroes before 5.

Hence the number is 0.0000000000529 meters, which is option C.

Let "x" equal the number of books that Jill started with. Solve for "x" :
____________________________________________
x – (1/2)x + 16 = 36 ;

1x – (1/2)) = (1/2)x ;

(1/2)x + 16 = 36 ;

Subtract "16" from EACH SIDE of the equation:

(1/2)x + 16 – 16 = 36 – 16 ;

(1/2)x = 20 ;

Multiply each side of the equation by "2" ;

2*(1/2)x = 20 * 2 ;

Answers

Two division equations for 16 times 7/8=14 are:
14/(7/8)=16

The reason that these equations work is because the inverse operation of multiplication is division. Any factors of the the multiplication equation can divide the product by the factor and the answer would be the other factor. Example:
AB=C
C/B= A
C/A=B
The product always has to be the first Number of the equation while either factor follows.

Explain: every equilateral triangle is isosceles, but not every isosceles triangle is equilateral

Answers

okay, in isosceles triangle two sides are equal and in equilateral triangle all sides are equal.
so in a equilateral triangle amy two sides can be equal, but in isosceles triangle all the three sides can't be equal.

By definition an isosceles triangle has AT LEAST 2 equal sides and AT LEAST 2 equal angles. In an equilateral triangle, all 3 sides and angles are equal. Since 3 is at least 2, an equilateral triangle is also an isosceles triangle. An isosceles triangle does not have to have 3 equal sides and angles (which is equilateral), so that means an isosceles triangle may not be equilateral.

Olivia ate 1/4 of a pizza if there were 12 slices of pizza how many slices did Olivia eat

Answers

Hello!

There are many ways you can solve this question. I'll show you a few. Way 1:

Convert 1/4 to a decimal by dividing its numerator by its denominator.

1 ÷ 4 = 0.25

1/4 is 0.25 as a decimal.
Then, multiply the amount of slices of pizza by the decimal form.

12 × 0.25 = 3

Way 2:

Since the numerator is 1, simply divide ths number of slices by the denominator of the fraction. You will get the same answer.

12 ÷ 4 = 3

First subtract 1.8y from 9.3y which is 7.5y, but since you are actually subtracting a larger number from a smaller number, you add a negative sign because your answer is less than 1. Then you add -6.3y to to -7.5y because you have two negatives. While it may seem like you should add them, you will subtract because you are adding essentially more negative to the negative number.

Morty buys and sells computer parts he bought two monitors for $25 each and later sold them for 88 each he bought four cases for $15 each and later sold them for $24 each if you buy five memory modules for $20 each and later sold them for $55 each

Answers

Final answer:

Morty earns a total profit of $337 from buying and selling monitors, cases, and memory modules by calculating the individual profits for each transaction and summing them up.

Explanation:

The question is asking for a calculation of the profit Morty makes on buying and selling computer parts. There are three transactions to consider:

Morty buys two monitors for $25 each and sells them for $88 each.He buys four cases for $15 each and sells them for $24 each.He buys five memory modules for $20 each and sells them for $55 each.

To find the total profit, we calculate the profit for each transaction:

Profit from monitors: (2 * $88) - (2 * $25) = $176 - $50 = $126Profit from cases: (4 * $24) - (4 * $15) = $96 - $60 = $36Profit from memory modules: (5 * $55) - (5 * $20) = $275 - $100 = $175

Then we sum these individual profits for the total profit:

Total profit = $126 + $36 + $175 = $337

The total profit that Morty makes from buying and selling these computer parts is $337.

Final answer:

Morty made a profit of $126 on the monitors, $36 on the cases, and $175 on the memory modules.

Explanation:

Morty bought two monitors for $25 each, costing him a total of $50. He later sold them for $88 each, earning a total of $176. He bought four cases for $15 each, costing him a total of $60. He later sold them for $24 each, earning a total of $96.

He also bought five memory modules for $20 each, costing him a total of $100. He later sold them for $55 each, earning a total of $275.

In summary, Morty made a profit of $126 on the monitors, a profit of $36 on the cases, and a profit of $175 on the memory modules.

Ki’von has a sink that is shaped like a half-sphere. The sink has a diameter of 20 inches. One day, his sink clogged. He has to use one of two different cups to scoop the water out of the sink. The sink is completely full when Ki’von begins scooping.

(a) What is the exact volume of the sink? Show your work. (3 points)

(b) One conical cup has a diameter of 8 in. and a height of 6 in. How many cups of water must Ki’von scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number. Show your work. (6 points)

c) One cylindrical cup has a diameter of 4 in. and a height of 6 in. How many cups of water must he scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number. Show your work. (6 points)

Answers

Step 1
Find the volume of a sink
Volume sink=(4/6)*pi*r³ (half-sphere)
Diameter=20 in--------------> r=D/2-----------> r=10 in
Volume sink=(4/6)*pi*10³---------> (2000/3)*pi in³ --------> 2093.33 in³

(a) What is the exact volume of the sink?
the answer part a) is (2000/3)*pi in³ (2093.33 in³)

(b) One conical cup has a diameter of 8 in. and a height of 6 in. How many cups of water must Ki’von scoop out of the sink with this cup to empty it?

volume of a conical cup=pi*r²*h/3
diameter=8 in--------------> r=4 in
h=6 in
volume of a conical cup=pi*4²*6/3-----------> 32*pi in³
if one cup---------------------> 32*pi in³
X---------------------------> (2000/3)*pi in³
X=(2000/3)*pi/(32*pi)------------> 20.83----------> 21 cups

the answer part b) is 21 cups

(c) One cylindrical cup has a diameter of 4 in. and a height of 6 in. How many cups of water must he scoop out of the sink with this cup to empty it?

volume of a cylindrical cup=pi*r²*h
diameter=4 in--------------> r=2 in
h=6 in
volume of a cylindrical cup=pi*2²*6-----------> 24*pi in³
if one cup---------------------> 24*pi in³
X---------------------------> (2000/3)*pi in³
X=(2000/3)*pi/(24*pi)------------> 27.77----------> 28 cups

the answer part c) is 28 cups

Answer: See each part below:

a) The volume of a sphere is (4/3)pi(r^3). If you input a 10 for the radius of sink, you will get 4000/3(pi). However, we have to divide it by 2 since it is a half-sphere. So the volume is 2000/3(pi).

For each cone, the volume formula is: pi(r^2)h/3.

b) With a radius of 4 and a height of 6, the volume is 100.53. Dividing the volume of the sink by this takes 21 scoops.

c) With a radius of 2 and a height of 6, the volume is 100.53. Dividing the volume of the sink by this takes 84 scoops.
