Answer:it is the second choice answer.

Step-by-step explanation:

You have to begin by simplifying each equation, and the answer you get has to be x is greater than or equal to 5.

The second equation:

4(x+8)-10> or= 42;

4x+32-10> or = 42;

4x+22>= 42; subtract 22 from both sides;

4x>=20; divide by 4;

X>=5

melamori03 [73]

Answer:

Interphase - First stage of Meiosis

Prophase I - Chromosomes pair up

Metaphase I = Chromosomes line up at equator

Anaphase I = Chromosomes pull part

Telophase I & Cytokinesis = Cell pinches in the middle

Prophase II = Two daughter cells formed

Metaphase II = Chromosomes line up at equator

Anaphase II = Sister chromatids pull apart

Telophase II & Cytokinesis = Cell pinches in the middle

Four grandaughter cells are formed.

A plane is approaching an aircraft carrier at 25° angle of elevation from 3.2 miles away how far above sea level is the plane

s2008m [1.1K]

Answer:

$Height\approx 1.35\ miles$

Step-by-step explanation:

The angle of elevation $=25\textdegree$

It is $3.2\ miles$ away from the point.

If we imagine a right triangle having an angle $25\textdegree$ .

Hypotenuse $=3.2$ , Opposite=Height from sea level $(h)$

$\sin 25=\frac{opposite}{hypotenuse}\\\\\sin 25=\frac{h}{3.2}\\\\h=3.2\times \sin 25\\\\h=3.2\times 0.4226\\\\h=1.3524\approx 1.35\ miles$
