Rules for exponents help?
JulijaS [17]

Your given expression has no "b", so you can rule out selections b, c, e.

The expression is not equal to 1, so you can rule out selection a.

That leaves selection d, which is the correct choice:

... d. 1/x^a

_____

The rule for exponents is that an exponent in the numerator is the same as its opposite in the denominator, and vice versa.

The exponent of <em>-a</em> in the numerator is the same as an exponent of <em>a</em> in the denominator.

You invested money in two funds. Last year, the first fund paid a dividend of 9% and the second a dividend of 3%, and you receiv
pishuonlain [190]

Answer: $7800 was invested at 9%

$5900 was invested at 3%

Step-by-step explanation:

Let x represent the amount invested in the fund that paid a dividend of 9%.

Let y represent the amount invested in the fund that paid a dividend of 3%.

Last year, the first fund paid a dividend of 9% and the second a dividend of 3%, and you received a total of $879. This means that

0.09x + 0.03y = 879- - - - - - - - - 1

This year, the first fund paid a 10% dividend and the second only 1%, and you received a total of $839. It means that

0.1x + 0.01y = 839 - - - - - - - - - -2

Multiplying equation 1 by 0.1 and equation 2 by 0.09, it becomes

0.009x + 0.003y = 87.9

0.009x + 0.0009y = 75.51

Subtracting, it becomes

0.0021y = 12.39

y = 12.39/0.0021

y = 5900

Substituting y = 5900 into equation 1, it becomes

0.09x + 0.03 × 5900 = 879

0.09x + 177 = 879

0.09x = 879 - 177

0.09x = 702

x = 702/0.09

x = 7800

. Mr. Wayne has a 3-year contract for his cell phone service. He pays $124.65 each month to cover everyone in his family. How mu
telo118 [61]

Answer:

$4,523.40

Step-by-step explanation:

The cell phone cost is $124.65 per month. With 12 months in a year, we multiply $124.65 x 12 to get the answer $1,507.80. Since one year equals $1,507.80, we multiply this answer by 3 for 3 years to get $4,523.40. Thus three years of service with $124.65 a month would equal $4,523.40.

In an election, a candidate got 82% votes. He won the beating his rival candidate by 576 votes. How many votes were polled?​
Slav-nsk [51]

Answer:

900

Step-by-step explanation:

A candidate got 82%votes.

Loosing candidate get=(100-82)=18%

Difference between two votes.

=(82-18)%=64%

Let be the Total vote is=x.

64% of the total vote=576

Or, 64 \%\times x= 576

Or,  \frac{64}{100}  \times x = 576

Or,x= \frac{576 \times 100}{64}

Or,x=900

∴The total votes that were polled are 900.
