Igoryamba

Answer:

y = 2g - 2

y + g = 16

Step-by-step explanation:

Given

Let g represent the green marbles

Let y represent the y marbles

Required

Determine the relationship between both marbles

The question says that y is 2 less than twice of g

This implies that: y = 2g - 2

The question further states that, Sarah has a total of 16 marbles;

This implies that y + g = 16

Tanya [424]

Answer:

0.44

Step-by-step explanation:

See the picture below.

Remember that the sine is the ratio of the length of the opposite leg to the length of the hypotenuse.

Perhaps you know SOHCAHTOA, where SOH means sine, opposite, hypotenuse.

For angle J, leg LK is the opposite leg.

The hypotenuse of the triangle is the side opposite the right angle, teh angle of 90°, which is angle L, so the hypotenuse is side KJ.

\sin J = \dfrac{opposite~leg}{hypotenuse}

\sin J = \dfrac{39}{89}

\sin J = 0.43820...
