5 0

Answer:

D. (-3/8) (-5/7) (-1/4)

Step-by-step explanation:

Hints:

- * - * + = +

+ * - * - = +

+ * + * + = +

- * - * - = -

A. (-3/8)(-5/7)(1/4)

= (-3*-5*1) / (8*7*4)

= 15/224

B. (3/8)(-5/7)(-1/4)

= (3*-5*-1) / (8*7*4)

= 15/224

C. (3/8)(5/7)(1/4)

= (3*5*1) / (8*7*4)

= 15/224

D. (-3/8) (-5/7) (-1/4)

= (- 3*-5*-1) / (8*7*4)

= (-15)/(224)

= -15/224

The correct option is

D. (-3/8) (-5/7) (-1/4)

Why do clouds stay up
Eduardwww [97]

Answer:

they can fall down and when they do it is call fog

Step-by-step explanation:

As warm, humid air rises through the lower atmosphere, it expands and cools, and some of it condenses into very tiny water droplets. Together these tiny droplets form a cloud. Depending on how this water condenses, you can end up with one of an array of cloud types

62,57,52,47,42 recursive formula
levacccp [35]

Answer:

1st sequence:  f(n)=f(n-1)-5 with f(1)=62.

2nd sequence: f(n)=f(n-1)+9 with f(1)=-15.

Step-by-step explanation:

The first sequence, to get the next term you just subtract 5 from the previous term.

The recursive form is f(n)=f(n-1)-5 with f(1)=62.

The sequence, to get the next term you just add 9 to the previous term.

The recursive form is f(n)=f(n-1)+9 with f(1)=-15.

Tell whether the angles are adjacent or vertical. Then find the value of x.
kondor19780726 [428]

Answer:

If two angles have common side and they shares common vertex, they are called adjacent angles.

When two lines crosses each other, the opposite angles are called vertical angles as they share same vertex.

Two angles shown in diagram are adjacent as they are on common side.

Both the angles are on a straight line, hence

Subtracting 109 from both sides

Both angles shown in diagram are opposite to each other, hence vertical angles.

As they are opposite to each other, they both are equal.

Subtracting x from both sides

Subtracting 1 from both sides

Both angles are having a common side means they are adjacent angles.

As they are on straight line, both angles will add up to 180 °.

Subtracting 96 from both sides

Dividing from 6 in both sides

Hope it will help :)

In ΔXYZ, the measure of ∠Z=90°, the measure of ∠X=57°, and XY = 8 feet. Find the length of YZ to the nearest tenth of a foo
vovikov84 [41]

Answer:

9.5 feet

Step-by-step explanation:

We solve this question using Sine rule

XY/sin X = YZ/Sin Z

From the question:

∠Z=90°

∠X=57°

XY = 8 feet.

8/sin 57 = YZ/sin 90

Cross Multiply

sin 57 × YZ = 8 × sin 90

YZ = 8 × sin 90/sin 57

YZ = 9.53891 feet

Approximately = 9.5 feet

Therefore, the length of YZ is 9.5 feet
