There is 12/15 of a pizza left. How many 3/10 pieces can be made from the leftover pizza? Show work please!

5 0

How many 1/3 pieces can be made from 2 pizzas, we know it is 6 and it is arrived by dividing 2 by 1/3 or multiplying by its reciprocal 3/1.

Hence to find how many 3/10 pieces can be made from 12/15 pizza, we have to divide 12/15 by 3/10 or multiplying by its reciprocal 10/3, i.e.

12/15 times 10/3= 8/3 or 2 2/3

What does that mean? This means that while 2 three-tenths pieces can be made, 2/3of 3/10 i.e. <span>2/3×3/10=2/10=1/5</span> or one-fifth of pizza will be left out.

So the answer is 2 three-tenths pieces can be made, and one-fifth pizza will be left out.

A 10-foot ramp must make an angle of 30degrees with the ground if it is to reach a certain window. What angle must a 15-foot ram

prohojiy [21]

<span>We know Sin theta is given by Perpendicular/ hypotenuse. Hence in this case the angle given is 30 degree and hypotenuse is given as 10 foot. Hence Sin 30= P/ 10 1/2= P/10 Hence on solving value of P is 5. Now we have to compute the theta value for Perpendicular as 5 and now the height of ramp is increased to 15 foot, hence hypotenuse is now 15 foot. Hence Sin theta= 5/15 On taking inverse of Sin Theta we will get the theta value as 19.47. Hence the angle of ramp should is 19.47 degrees.</span>

Answer:

La calculadora y el cuaderno costaba 9 y 1,8 euros hace tres días.

Step-by-step explanation:

A partir del enunciado podemos construir el sistema de ecuaciones lineales:

Hace tres días:

$x+y = 10.80$ (1)

Actualmente:

$1.08\cdot x + 0.9\cdot y = 11.34$ (2)

Donde:

$x$ - Precio de la calculadora.

$y$ - Precio del cuaderno.

Por métodos algebraicos, tenemos que el sistema de ecuaciones tiene la siguiente solución:

$x = 9$ , $y = 1.8$

La calculadora y el cuaderno costaba 9 y 1,8 euros hace tres días.

Answer:

$80,000

Step-by-step explanation:

Under a Comparative negligence theory, people involved in an accident are entitled to compensation according to their contributions towards the accident. In this case, Annette contributed 20% to the collision and, thus, should receive 100% - 20% of her total loss determined by the jury. Annette should be awarded:

$A= \$ 100,000*(1-0.2)\\A=\$ 80,000$

Therefore, the jury should award Annette $80,000

Answer: 1 over 2

Step-by-step explanation: if you take the coordinates of the pre-image, letter A. which is (2,6) and the coordinates of the transformed image A’ which is (1,3) and only use the first number of the coordinates. You would put the number of of the pre-image as the denominator and the number of the transformed image as the numerator. And It would become 1/2.
