A farmer plows a corn field in the shape of a rectangle that has an area of 15840 square yards if the length of the field is 132

igomit [66]

Answer:

<u>Width= 120</u>

<u />

Step-by-step explanation:

We know that <u>L*W= A</u>

So lets put in the variables we know into the equation.

<u>L= 132 yards</u>

<u>A= 15840</u>

132 * W= 15840

All we need to do is <u>divide 15840 by 132</u>

<u>15840/132= 120</u>

<u>W=120</u>

In Boston taxicabs charge an initial fare and an additional amount for every mile traveled. Tahira is having trouble figuring ou

nlexa [21]

Answer:

The taxi charges $2.5 for every mile.

Step-by-step explanation:

We are given the following in the question:

Let x be the initial taxicab fare and y be the additional amount for every mile traveled.

Cost for a two mile ride = $7.00

Thus, we can write the equation:

$x + 2y = 7$

Cost of a nine mile ride = $24.50

Thus, we can write the equation,

$x + 9y = 24.50$

Solving the two equation by elimination method, we have,

$x + 9y - (x + 2y) = 24.50 - 7\\7y = 17.5\\y = 2.5\\\Rightarrow x + 2(2.5) = 7\\x = 2$

Thus, $2 is the initial fare and $2.5 is the cost for every mile traveled.

a volleyball team drank 7.5 liters of water during their match. how many milliliters of water did the volleyball team drink?

RSB [31]

The difference between liters and milliliters is three decimal places so either move the decimal over three places and put in two zeros in the empty places or just multiply 7.5 by 1,000 (three zeros = 1 for each decimal place you need to move the decimal). 7.5 liters of water = 7,500 milliliters of water.

At a gas station, suppose that 45% of the customers purchase premium grade gas. Assume that these customers decide independently

valkas [14]

Answer:

The answer to the question is

The probability that at least one of the next three customers purchases premium gas is the complement of the probability that none of the next three customers purchase premium gas = 1 - (1-P(A))³ = 0.834

Step-by-step explanation:

The probability that a customer would purchase premium grade = 45 %

That is P(A) = 0.45 and

The probability that the customer would purchase another grade = P(B) = 0.55

Therefore the probability of at least one of the next three customers purchase premium gas is

P(k=0) = (1 - P)ⁿ and the probability of at least one customer purchases premium gas is the compliment of the probability that the next three customers purchase another gas brand

that is (1 - P(A))×(1 - P(A))×(1 - P(A)) = P(B)×P(B)×P(B) = 0.55³ and the complement is 1 - 0.55³ = 0.834
