Answer:

D = 49/40

Step-by-step explanation:

Solve for D:

D - 3/5 = 5/8

Put each term in D - 3/5 over the common denominator 5: D - 3/5 = (5 D)/5 - 3/5:

(5 D)/5 - 3/5 = 5/8

(5 D)/5 - 3/5 = (5 D - 3)/5:

(5 D - 3)/5 = 5/8

Multiply both sides of (5 D - 3)/5 = 5/8 by 5:

(5 (5 D - 3))/5 = 5×5/8

5×5/8 = (5×5)/8:

(5 (5 D - 3))/5 = (5×5)/8

(5 (5 D - 3))/5 = 5/5×(5 D - 3) = 5 D - 3:

5 D - 3 = (5×5)/8

5×5 = 25:

5 D - 3 = 25/8

Add 3 to both sides:

5 D + (3 - 3) = 25/8 + 3

3 - 3 = 0:

5 D = 25/8 + 3

Put 25/8 + 3 over the common denominator 8. 25/8 + 3 = 25/8 + (8×3)/8:

5 D = 25/8 + (8×3)/8

8×3 = 24:

5 D = 25/8 + 24/8

25/8 + 24/8 = (25 + 24)/8:

5 D = (25 + 24)/8

25 + 24 = 49:

5 D = 49/8

Divide both sides by 5:

D = (49/5)/8

8×5 = 40:

Answer: D = 49/40

How can you tell before dividing taht the first digit of the quotient 2,874 divided by 3 is in the hundreds place?
torisob [31]
When you divide, you're doing the oposite of multiplication. To know that your partical answer is going to be in the hundreds place is you follow the pattern.
2874/3=958
you take the 3 and you divide it by the last two didits of the number given (28) and that'll get you into your hundreds place.
Hope this helped! :-)

LMNP is a parallelogram.
Amanda [17]

A rectangle is a parallelogram with four right angles.

That's why in order to prove that LMNP is rectangle you have to show that LP is perpendicular to PN.

Solution:

The coordinates of vertices are L(-4,1), P(-3,-1) and N(3,2), then

\overrightarrow{PL}=(-4-(-3),1-(-1))=(-1,2),\\ \overrightarrow{PN}=(3-(-3),2-(-1))=(6,3).

Find the dot product:

\overrightarrow{PL}\cdot \overrightarrow{PN}=-1\cdot 6+2\cdot 3=-6+6=0.

Since the dot product of two vectors is equal to zero, these vectors are perpendicular.

LMNP is a parallelogarm, then

m\angle P=m\angle M=90^{\circ},\\ m\angle L=m\angle N=180^{\circ}-90^{\circ}=90^{\circ}.

You show that all angles are right, this means that parallelogram LMNP is a rectangle.

Answer: correct choice is D.

The simplified expression of (x^0 y^2/3 z^-2y^)^2/3 divided by (x^2 z^1/2)^-6 is x^(12) y^(10/9) z^(-1/3)

<h3>How to simplify the expression?</h3>

The algebraic statement is given as:

(x^0 y^2/3 z^-2y^)^2/3 divided by (x^2 z^1/2)^-6

Rewrite the algebraic statement as:

[(x^0 y^2/3 z^-2y)^2/3]/[(x^2 z^1/2)^-6]

Evaluate the like factors

[(x^0 y^(2/3+1) z^-2)^2/3]/[(x^2 z^1/2)^-6]

Evaluate the sum

[(x^0 y^5/3 z^-2)^2/3]/[(x^2 z^1/2)^-6]

Expand the exponents

[(x^(0*2/3) y^(5/3 * 2/3)z^(-2*2/3)]/[(x^(2*-6) z^(1/2*-6)]

Evaluate the products

[(x^0 y^(10/9) z^(-4/3)]/[(x^(-12) z^(-3)]

Apply the quotient law of indices

x^(0+12) y^(10/9) z^(-4/3+3)

Evaluate the sum of exponents

x^(12) y^(10/9) z^(-1/3)

Hence, the simplified expression of (x^0 y^2/3 z^-2y^)^2/3 divided by (x^2 z^1/2)^-6 is x^(12) y^(10/9) z^(-1/3)
