The answer is 1.25%
Because $40 is 100% then 40 cents is 1%
50 cents is 1% and 1/4 of a percent
Add 1 and 1/4 to get 1.25

Answer:

1%

Step-by-step explanation:

We need our two numbers to have the same units. Since one number is in cents and the other is in dollars, we should change one of them. It could be either one.

Both numbers in cents:

50/4000

OR, both numbers in dollars:

.50/40.00

Either of these will work. Divide, you will get a decimal answer. Then multiply by 100 to change to a percent.

50÷4000 (OR .5/40)

= 0.0125

times by 100

0.0125 × 100

= 1.25% but the directions said to round to the nearest whole number, that's 1%

The length of the rope needed is 15 feet

Given the following parameters;

  • Height of the pole = 9 foot
  • The distance from the <u>rope away from the base </u>of the pole is 12 feet

Required

  • Length of the rope.

To get the length of the rope, you will use the pythagoras theorem expressed as:

  • c² = a² + b²

Substituting the given parameters:

c² = 9² + 12²

c² =81 + 144

c² = 225

c = √225

c = 15 feet

Therefore the length of the rope needed is 15 feet

Suppose that in a certain county 37% of voters are registered as Democrats, 29% as Republicans, 7% as Green party, and the rest
Fantom [35]

Answer:

0.66

Step-by-step explanation:

GIVEN: Suppose that in a certain county 37\% of voters are registered as Democrats, 29\% as Republicans, 7\% as Green party, and the rest are considered Independents. You conduct a poll by calling registered voters in the county at random.

TO FIND: Probability that the first call will be to either a Democrat or a Republican.

SOLUTION:

Lets total population of county be 100x.

voters registered as Democrats =37\%=\frac{37}{100}\times100x

                                                     =37x

voters registered as Republicans =29\%=\frac{29}{100}\times100x

                                                       =29x

voters registered as Green party =7\%=\frac{7}{100}\times100x

                                                       =7x

Probability that first call will be to Democrats P(A)=\frac{\text{total democrats}}{\text{total voters}}

                                                                                    =\frac{37x}{100x}=0.37

Probability that first call will be to Republican P(B)=\frac{\text{total republicans}}{\text{total voters}}

                                                                                     =\frac{29x}{100x}=0.29

probability that the first call will be to either a Democrat or a Republican

=P(A)+P(B)

=0.37+0.29

=0.66

Hence the probability that the first call will be to either a Democrat or a Republican is 0.66
