Answer:

x=-1

Step-by-step explanation:

multiplique el paréntesis por -6

10x-6+18x-12x+24=2

agripe los términos semejantes

16x-6+24=2 ...... 16x+18=2

mueva la constante al lado derecho y cambie su signo

16x=2-18

calcula la diferencia

16x=-16

divida ambos lados de la ecuación entre 16

x=-1

A. The formula to find the volume of a cylinder (that's what the first shape is):
pi r^2 h So, when you plug in the numbers and calculate, you get: 24.5pi

The formula to find the volume of a rectangular prism is: length x width x height.
6 x 9 = 54 54 x 2 = 108

V of the first pan = 24.5pi V of the second pan = 108 The second pan has a larger volume.

HEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEELLLLLLLLLLLLLLLLLLLLLLLLP What is the simplified value of the expression below?

olganol [36]

Answer:

100

Step-by-step explanation:

start with what's in the parenthesis':

8 (9.75 - 3.25) + 12 x 4 = 8 (6.50) + 12 x 4

then take the number outside of the parenthesis' time the number inside of them:

8 (6.50) + 12 x 4 = 52 + 12 x 4

now, take the product of the two number on the right side of the addition sign:

52 + 12 x 4 = 52 + 48

finally, add the final two numbers together:

52 + 48 = 100

Identify sinJ as a fraction and as a decimal rounded to the nearest hundredth.

KiRa [710]

In the given right triangle, the trigonometric ratio, sin J has a fractional value of 5/13 and a decimal value of 0.39.

In trigonometry, for a right triangle, the sine (sin) of any angle θ is given as the ratio of its opposite side to the hypotenuse of the triangle, that is, sin θ = (opposite side)/(hypotenuse).

In the question, we are asked to find the trigonometric ratio, sin J, for the given right triangle JKL.

The side opposite to angle J is KL, which has a value of 3 units.

The hypotenuse of the given right triangle is JK, which has a value of 7.8 units.

Thus, sin J can be calculated as:

sin J = KL/JK = 3/7.8 = 5/13 = 0.39.

Thus, in the given right triangle, the trigonometric ratio, sin J has a fractional value of 5/13 and a decimal value of 0.39.
