Answer:

A fourth is when you have one of four pieces. If there are four pieces and each one is 16 inches long, multiply four by 16. 4 x 16 = 64

Factor the expression completely.

It would be A because -2.25*3=-6.75 and -2.25*x=-2.25x giving us are end answer of, -6.75+2.25x

Enjoy!=)

(P.s. I am not 100% sure if this is completely factored but it should be)

Si "m" es el lado mayor de un triángulo, dos cuyos ángulos interiores miden 30° y 60°, entonces el perímetro del triángulo es

lions [1.4K]

Answer:

$perimetro = \dfrac{(3 + \sqrt{3})m}{2}$

Step-by-step explanation:

triángulo 30°-60°-90°

$1~:~\sqrt{3}~:~2$

$1m~:~m\sqrt{3}~:~2m$

$\dfrac{m}{2}~:~\dfrac{m\sqrt{3}}{2}~:~m$

$perimetro = \dfrac{m}{2} + \dfrac{m\sqrt{3}}{2} + m$

$perimetro = \dfrac{m}{2} + \dfrac{m\sqrt{3}}{2} + \dfrac{2m}{2}$

$perimetro = \dfrac{m + m\sqrt{3} + 2m}{2}$

$perimetro = \dfrac{3m + m\sqrt{3}}{2}$

$perimetro = \dfrac{(3 + \sqrt{3})m}{2}$

Leah has 28 more marbles than Dan. 1/3 of Leah’s marbles is equal to 4/5 of Dan’s marbles. Find the number of marbles Leah has.

konstantin123 [22]

Answer:

Leah has 48 marbles.

Step-by-step explanation:

Represent the number of marbles that each person has by L and D.

Leah has 28 more marbles than Dan: L = D + 28.

Then (1/3)L = (4/5)D. Here the LCD is 15, and so multiplying this equation by 15 will remove the fractions: 15(1/3)L = 15(4/5)D.

Therefore, 5L = 12D, and D = 5L/12.

Then, since L = D + 28, L = (5/12)L + 28, or

12L = 5L + 336, or

7L = 336, or

L = 336/7 = 48.

Leah has 48 marbles. That means that Dan has 20 marbles.
