Jolie sends between 22 and 23 text messages per day. Each text message costs $0.89. Suppose Jolie's cellular bill spans a period

kondor19780726 [428]

Answer:

C. $945

Step-by-step explanation:

Cost of 1 cellular bill = (number of text msgs per day) x (cost per text msg) x (number of days in billing period)

in this case, it is given that :

cost per text msg = $0.89

number of texts per day = 22 or 23

billing cycle = 6 weeks = 6 x 7 = 42 days

hence,

Cost of 1 cellular bill = (22 or 23) x $0.89 x 42 days

if she sends 22 messages,

Cost of 1 cellular bill = (22) x $0.89 x 42 days= $822.36

if she sends 23 messages,

Cost of 1 cellular bill = (2) x $0.89 x 42 days= $859.74

if we compare thse 2 numbers that we have calculated with the choices, the closest match would be C. $945. The rest are just too far away in comparison.

The area of the original plot is

200 ×300 =60000

The problem

$(x + 200)(x + 300) = 120000 \\ proof.300 \times 400 = 120000 \\ x {}^{2} + 500x + 60000 = 120000 \\ x {}^{2} + 500x - 60000 = 0 \\ (x + 600(x - 100) = 0 \\so.... \\ x = - 600(reject) \: x = 100 \\ x = 100meter \\ proof.300 \times 400 = 120000$

Hope this help :)

What is the value of 624 to the power of 1/4

brilliants [131]

Any number raised to a fraction just means that you take the number to the power of the numerator of the fraction and then root it by the denominator of the fraction.

In $\frac{1}{4}$ , we raise 624 to $1$ and then root it by $4$ which gives:

$\sqrt[4]{624^1}$ = $\sqrt[4]{624} =$ approximately $5$ as $5^4$ is $625$ .

$4.997$ :D
