In the expression 852.763 x 10?, what is the missing exponent that would result in a number that is 1,000 times the value of 852
Molodets [167]

Answer:

The missing exponent = power of 3

852.763 x 10³ = 852763

Step-by-step explanation:

The expression 852.763 x 10?

A number that is 1,000 times the value of 852.763 is calculated as:

852.763 × 1000 = 852763

Converting this to exponent

852.763 × 10³ = 852763

Therefore, the missing exponent that would result in number that is 1,000 times the value of 852.763 is power of 3 meaning 10³

PLEASE HELP ASAP 25 PTS + BRAINLIEST TO RIGHT/BEST ANSWER
m_a_m_a [10]

Answer:

d 20.4 years

Step-by-step explanation:

The equation is

A = Pe ^(rt)

We know that r = .034

We want the money to double  so A = 2P

Substitute in

2P = P e ^(.034t)

Divide by P

2P/P = P/P e ^(.034t)

2 = e^ (.034t)

Take the natural log on each side

ln (2) = ln(e^ (.034t))

ln (2) = .034t

Divide by .034

ln (2) /.034 = .034t/.034

ln (2)/.034 = t

20.3867 =t

<h3>Answer:  22</h3>

===============================================

Explanation:

  • x = measure of angle 1 = angle WXY
  • 2x = twice the measure of angle 1 = measure of angle 2 = angle YXZ

The two angles mentioned combine to form angle WXZ which is 66 degrees.

angle1+angle2 = angle WXZ

x+2x = 66

3x = 66

x = 66/3

x = 22

Angle 1 is 22 degrees and angle 2 is 22*2 = 44 degrees.

Check:

angle1+angle2 = 22+44 = 66 = angle WXZ
