Answer:  2) 1.45 × 10⁻⁵

               3) 3.99 × 10⁴

<u>Step-by-step explanation:</u>

  (5.0 x 10⁻⁸)(2.9 x 10²)

= (5.0)(2.9) x 10⁻⁸⁺²

=     14.5     x 10⁻⁶

=     1.45     x 10⁻⁵

 3.25 x 10⁴      ⇒      3.25 x 10⁴

+<u> 7.4  x  10³ </u>     ⇒     <u> 0.74 x 10⁴</u>

                                  3.99 x 10⁴

Answer:

90°

Step-by-step explanation:

It looks slightly obvious, but here's the complicated explanation.

Converse of the Consecutive Interior Angles Theorem. Solve.

x+96+x+96=180

Simplify.

2x+192=180

Subtraction Property of Equality (subtract 192 from both sides to isolate 2x).

2x=-12

Division Property of Equality (divide both sides by 2 to isolate x).

x=-6

Now that you have your x value, plug it in into your bolded equation.

x+96

-6+96

Simplify.

90°

How many solutions does the system of equations have?
statuscvo [17]
5x - 20y = 60...reduce by dividing by 5
x - 4y = 12
this is the same as the other equation....therefore, it is the same line...meaning infinite solutions
=============
y - 7x = -14
y = 7x - 14.....slope = 7, y int = -14

7y - 49x = -2
7y = 49x - 2
y = 7x - 2/7.....slope is 7, y int is -2/7

if the slopes are the same, but the y int are different, then u have a parallel lines with no solutions

HELP !!! | 20 Points.
RUDIKE [14]

Answer:

No. The ladder is too steep.

Step-by-step explanation:

Length of ladder = 17 feet.  This is the hypotenuse.

Side a of a right triangle = 16.6

To answer this, you need one of the trigonometric functions.  

Opposite = 16.5

hypotenuse = 17

The function you need is the sine function.

Sin(theta) = opposite / hypotenuse

sin(theta) = 16.5 / 17

Sin(theta) = 0.97059

theta = sin-1(0.07059)

theta = 76.07

No the ladder is too steep.
