Tracy needs to find the length and width of the equipment room where she works. The room is 2 meters longer than it is wide. The

Alekssandra [29.7K]

Answer:

The answer to your question is: width = 3 meters

Step-by-step explanation:

Data

Perimeter = 16 meters

The room is 2 meters longer than its width, then length = width + 2

Perimeter = 2 length + 2 width

16 = 2(width + 2) + 2 width

16 = 2 width + 4 + 2 width

16 = 4 width +4

16 - 4 = 4 width

12 = 4 width

12/4 = width

3 = width

length = 3 + 2 = 5 meters

150 students were surveyed on how many text messages to send in a date for different devices. let X represent the number of stud

kakasveta [241]

Given that the total number of students that sent messages = 150 students

a) To obtain the equation to represent the number of students who send text messages, we will sum up the variables in the Venn diagram and equate it to 150.

$\begin{gathered} 75+x+3x+x=150 \\ x+3x+x=150-75 \\ 5x=75 \end{gathered}$

Hence, the equation is

$5x=75$

b) Solving for x

$\begin{gathered} 5x=75 \\ x=\frac{75}{5}=15 \\ \therefore x=15 \end{gathered}$

Therefore, x = 15.

c) The total number of student that uses cell phone = 75 + x = 75 + 15= 90students

The total number of students that sent messages = 150students

The formula for probability is,

$\text{Probability = }\frac{\text{Number of students that uses cell phone}}{\text{Total number of students}}$

Hence,

$P(\text{Number of students that uses cell phone)}=\frac{90}{150}=\frac{3}{5}$

Therefore, the probability that a randomly chosen student uses their cell phone to send text messages is 3/5.

Instructions: Factor 715 as a product of primes.

Drupady [299]

Answer:

{1, 5, 143}

Step-by-step explanation:

715 is evenly divisible by 5, so one factor of 715 is 5 and the next is 715/5, or 143. 143 is not factorable further. Thus, the factors of 715, in ascending order, are 1, 5 and 143.
