Answer:

$44,313.75

Step-by-step explanation:

First, we need to turn the km into meters. There are 1000 meters in a km meaning we need to multiply each of these values by 1000.

0.101 km * 1000= 101 meters

0.065 km * 1000 =  65 meters

Now we need to multiply these values together to find the area of the field

101m * 65m = 6,565m^{2}

Finally, we need to multiply this area by the cost per square meter

6,565m^{2} / 6.75 = $44,313.75

The total repair will cost $44,313.75

No, because she could receive as low as 49% of the vote.

Yes, because she could receive as much as 77% of the vote.

Yes, because the poll stated that she will win with 63% of the vote.

Answer:

No, because she could receive as low as 49% of the vote.

Step-by-step explanation:

Given that:

Poll suggestion = 63%

Margin of Error (E) = 14%

This means that; the range or interval in which the vote obtained could fall would be ;

Poll suggestion ± margin of Error

63% ± 14%

Lower bound attainable = (63% - 14%) = 49%

Upper bound attainable = (63% + 14%) = 77%

Since, winning actually requires obtaining atleast half of the votes (that is 50%) ; and suggested poll suggested votes could fall as low as 49% ; then Janice can't be so confident of victory.

Evaluate. 58−(14)2=58-142= ________
nasty-shy [4]

For this case we have the following expression:

58- (14) ^ 2

The first step is to solve the quadratic term.

We have then:

58- (14) ^ 2 = 58-196

Then, the second step is to subtract both resulting numbers:

58- (14) ^ 2 = -138

We observe that the result obtained is a negative number.

Answer:

The result of the expression is given by:

58- (14) ^ 2 = -138

katrin [286]
For this case we have the following equation:
 d (t) = 12t + 20

 The variables are:
 t: time in hours
 d (t): distance traveled in miles.
 We evaluate the distance traveled after 4 hours.
 So we have that for t = 4:
 d (4) = 12 (4) +20

d (4) = 48 + 20

d (4) = 68
 Answer:
 
d (4) = 68
 
This means that after 4 hours Joanna cycled for 68 miles total
