Si el recíproco del m% de p se divide por el recíproco del m% de q resulta: A) pq/100 B)pq C)1/pq D)p/q E)q/p
Answer:
E) q / p
Step-by-step explanation:
Spanish
m% de p = pf / 100
m% de q = mq / 100
El recíproco se obtiene haciendo que el numerador sea el denominador y el denominador el numerador.
El recíproco de m% de p = 100 / mp
El recíproco de m% de q = 100 / mq
Divisor
100 / mp / 100 / mq
= 100 / mp * mq / 100
= mq / mp
= q / p
English
If the reciprocal of m% of p is divided by the reciprocal of m% of q, the result is: A) pq / 100 B) pq C) 1 / pq D) p / q E) q / p
m% of p= mp/100
m% of q= mq/100
The reciprocal is obtained by making the numerator the denominator and the denominator the numerator
The reciprocal of m% of p= 100/mp
The reciprocal of m% of q= 100/mq
Dividing
100/mp/ 100/mq
=100/mp* mq/100
= mq/mp
= q/p

Answer:
I'd have to say, C: 13
Step-by-step explanation:
Answer:
C. 13 meters
Step-by-step explanation:
[tex]a^{2} + b^{2} = c^{2}[/tex]
[tex]c^{2} = 12^{2} + 5^{2}[/tex]
12 x 12 = 144
5 x 5 = 25
[tex]c^{2} = 144 + 25[/tex]
[tex]c^{2} = 169[/tex]
[tex]\sqrt{c^{2} } = \sqrt{169}[/tex]
c = [tex]\sqrt{169}[/tex]
169 ÷ 13 = 13
1 [tex]\sqrt{13 m}[/tex]

Shelby made a mistake in her checkbook. She wrote a check for $8.50 to rent a video game but mistakenly recorded it in her checkbook as an $8.50 deposit. Part A: Which point represents each of Shelby's transaction on the number line below? Explain the difference between these two transactions. Part B: Use absolute value to explain how a debt of $8.50 and a deposit of $8.50 are similar.
Answer:
Part A
The first transaction which is to write a check of $8.50 is a debit transaction which carries a negative sign while
The second transaction which states that she wrote it as a deposit carries a positive sign because deposit means to add
Part B
The absolute value of a number is never negative.
|-8.50| = 8.50
Step-by-step explanation:
Part A: Which point represents each of Shelby's transaction on the number line below? Explain the difference between these two transactions.
The firsts transaction says:
She wrote a check for $8.50 to rent a video game.
Writing a check of $8.50 is a debit to her bank account. This is a negative value because $8.50 is taken from the money in her bank account.
Mathematically this means, -$8.50
The second transaction states that:
She mistakenly recorded it in her checkbook as an $8.50 deposit.
Mathematically, a deposit means a positive action, where money is added to the money in her bank account.
Hence,
+$8.50
Part B: Use absolute value to explain how a debt of $8.50 and a deposit of $8.50 are similar.
In mathematics it is important to note that:
The absolute value of a number is never negative.
Hence,
Debt of $8.50 = -8.50
Deposit of $8.50 = +8.50
Hence,
|-8.50| = 8.50
3/5 pencils sold in the morning. 1/4 of the remainder in the afternoon. If 200 more pencils were sold in the morning than afternoon, how many pencils did they start with
Answer:
x = total pencils = 400 pencils
Step-by-step explanation:
Let
x = total pencils
Pencils sold in the morning = 3/5x
Remaining pencil = x - 3/5x
= 5x-3x/5
= 2/5x
Pencils sold in the afternoon = 1/4 of the remainder
= 1/4 * 2/5x
= 2/20x
= 1/10x
Pencils sold in the afternoon = 1/10x
3/5x + 200 = 1/10x
3/5x - 1/10x = 200
(6x-x)/10 = 200
5/10x = 200
1/2x = 200
x = 200 ÷ 1/2
= 200 × 2/1
x = 400 pencils
x = total pencils = 400 pencils
Calculate the volume of the shaded space. Round to the nearest tenth, if necessary.
Answer:
Volume of the shaded space = 4480.0 yd³
Step-by-step explanation:
Volume of the shaded space = Volume of cuboid - Volume of Pyramid placed inside
Volume of cuboid = Length × Width × Height
= 28 × 12 × 20
= 6720 yd³
Volume of pyramid = [tex]\frac{1}{3}(\text{Area of the base})(\text{Height})[/tex]
= [tex]\frac{1}{3}(28\times 12)(20)[/tex]
= 2240 yd³
Volume of the shaded space = 6720 - 2240
= 4480.0 yd³

A parallelogram has four angles that are the same measure. Is it a square?
Choose Yes or No to tell if the answer and explanation is correct.
Yes. Only squares have four angles that are the same measure.
Yes. It could be a square if all sides are also the same measure.
No. If the sides are not the same length, it is not a square.
No. The figure is a rhombus.
Answer:
Yes
Step-by-step explanation:
Yes. It could be a square if all sides are also the same measure.
A parallelogram will be a square when all four sides are of equal in length and all four angles are same.
A parallelogram is a quadrilateral with opposite sides parallel . A quadrilateral with equal sides is called a rhombus, and a parallelogram whose angles are all right angles is called a rectangle.A square is a parallelogram when all four sides of parallelogram are same and all four angles are equal to 90 degree.Learn more:

Hello and Good day,
This question is relating to probability and it can come in percentages and fractions. I will follow directions as the problem states and provide both.
1. There is a 1/20 or 5% chance that the dart would land on section 20.
2. There is a 10/20 or 50% chance that the dart would land on an odd number.
There are 10 odd numbers present on the dart board.
3. 4/20 or 20%
There are 4 numbers greater than 16.
4. 0/20 or 0%
This is because there are no 25's on the dart board
5. 17/20 or 85%
This is because there are 17 numbers that aren't 4, 5, or 6.
6. 7/20 or 35%
There are 7 numbers less than 8.
7. 20/20 or 100% chance

Please help, due soon. Find the length of each arc. Use exact answer
Answer:
C
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr × [tex]\frac{285}{360}[/tex]
= 2π × 18 × [tex]\frac{19}{24}[/tex]
= 36π × [tex]\frac{19}{24}[/tex] ( cancel 36 and 24 by 12 )
= 3π × [tex]\frac{19}{2}[/tex]
= [tex]\frac{57\pi }{2}[/tex] → C

(6, - 3, 1) and (8,9,-11) find the angle between the vector
Answer:
The angle between the two vectors is 84.813°.
Step-by-step explanation:
Statement is incomplete. Complete form is presented below:
Let be (6,-3, 1) and (8, 9, -11) vector with same origin. Find the angle between the two vectors.
Let [tex]\vec u = \langle 6, -3, 1 \rangle[/tex] and [tex]\vec v = \langle 8,9,-11 \rangle[/tex], the angle between the two vectors is determined from definition of dot product:
[tex]\theta = \cos^{-1} \left(\frac{\vec u \,\bullet \,\vec v}{\|\vec u\|\cdot \|\vec v\|} \right)[/tex] (1)
Where:
[tex]\vec u[/tex], [tex]\vec v[/tex] - Vectors.
[tex]\|\vec u\|[/tex], [tex]\|\vec v\|[/tex] - Norms of each vector.
Note: The norm of a vector in rectangular form can be determined by either the Pythagorean Theorem or definition of Dot Product.
If we know that [tex]\vec u = \langle 6,-3,1 \rangle[/tex] and [tex]\vec v = \langle 8, 9,-11 \rangle[/tex], then the angle between the two vectors is:
[tex]\theta = \cos^{-1}\left[\frac{(6)\cdot (8) + (-3)\cdot (9) + (1)\cdot (-11)}{\sqrt{6^{2}+(-3)^{2}+1^{2}}\cdot \sqrt{8^{2}+9^{2}+(-11)^{2}}} \right][/tex]
[tex]\theta \approx 84.813^{\circ}[/tex]
The angle between the two vectors is 84.813°.

Use the quadratic formula to solve for x.
6x²-3x=1
Round your answer to the nearest hundredth.
If there is more than one solution, separate them with commas.
If we know the quadratic formula, the quadratic formula is
x = [-b ± √(b²- 4ac)] / 2a
Gosh! So overwhelming! But let's look at the composition of a quadratic equation:
ax² + bx + c = 0
And we have 6x² - 3x = 1. So, what do we do? We need to put this quadratic equation into an easy form to find the value of a, b, and c to plug in to the equation.
We can just minus one on both sides to get this:
6x² - 3x - 1 = 0
Is it in the form of ax² + bx + c? Yes! a = 6, b = -3, and c = -1. Now, all we have to do is plug it into the quadratic formula.
x = [-b ± √(b²- 4ac)] / 2a
x = [-(-3) ± √((-3)²- 4(6)(-1))] / 2(6)
[3 ± √(9- 4(6)(-1))] / 12
[3 ± √(9 + 24)] / 12
[3 ± √(33)] / 12
At this point, we should just use a calculator, and recognize we have two answers because of the plus-or-minus sign! (or this sign: ±)
[3 ± √(33)] / 12
1) [3 + √(33)] / 12 = 0.73 approximately
2) [3 - √(33)] / 12 = -0.23 approximately
So, x=0.73 and x= -0.23.
