6:55 3:31
The number of hours Janice worked in a week is 44 hours.
Given that, Janice has recorded on her time sheet for the week.
What is a clock?A clock or a timepiece is a device used to measure and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month and the year.
Now,
Time in Time out
7:05 2:58
7:30 5:01
8:01 4:32
7:22 4:46
6:55 3:31
Between 7:05 and 2:58 the number of hours is 7 hours 53 minutes
Between 7:30 and 5:01 the number of hours is 9 hours 31 minutes
Between 8:01 and 4:32 the number of hours is 8 hours 31 minutes
Between 7:22 and 4:46 the number of hours is 9 hours 24 minutes
Between 6:55 and 3:31 the number of hours is 8 hours 36 minutes
Now, (7+9+8+8+8)+(53+31+31+24+36)
= 40 hours + 175 minutes
= 40 hours + 2 hours 55 minutes
= 43 hours 55 minutes
= 44 hours
Therefore, the number of hours Janice worked in a week is 44 hours.

Use synthetic division to solve the following: 2x^4 + 11x^3 + 13x^2 + 2x – 8 ÷ x +4
Answer:
x=-5
Step-by-step explanation:
En un aeropuerto dos aviones A1 y A1 se acercan para aterrizar, si la ecuación de la trayectoria del primero es -x+2y-100=0, mientras que la ecuación de la trayectoria del segundo es de –x+200 +2y, determina si existe el riesgo de que sufran un choque entre ellos.
No hay solución en la que ambas trayectorias estén en la misma posición, puesto que no existe el riesgo de que sufran un choque entre ellos.
-------------------------
La trayectoria del primero es:
[tex]-x + 2y - 100 = 0[/tex]
[tex]x_1 = 2y - 100[/tex]
Para el segundo, tiene-se que:
[tex]-x + 200 + 2y = 0[/tex]
[tex]x_2 = 2y + 200[/tex]
Igualando los valores de x:
[tex]x_1 = x_2[/tex]
[tex]2y - 100 = 2y + 200[/tex]
[tex]0y = 300[/tex]
No hay solución en la que ambas trayectorias estén en la misma posición, puesto que no existe el riesgo de que sufran un choque entre ellos.

The depth of water in a water tower that is draining is decreasing at a constant rate of 1.75 feet per hour. If
the depth after 6 hours of draining is 8 feet then write an equation for the water depth, d, as a function of the
amount of time it's been draining, t, in hours.
The linear function for the depth of water after t hours is given by:
[tex]d(t) = 17 - 1.5t[/tex]
The format of a linear function is given as follows:
[tex]d(t) = d(0) - at[/tex]
In which:
d(0) is the y-intercept, which is the initial value.a is the slope, which is the rate of change.The depth of water in a water tower that is draining is decreasing at a constant rate of 1.75 feet per hour, which means that [tex]a = -1.75[/tex], thus:
[tex]d(t) = d(0) - 1.5t[/tex]
The depth after 6 hours of draining is 8 feet, which means that when [tex]t = 6, d(t) = 8[/tex]. This is used to find d(0).
[tex]d(t) = d(0) - 1.5t[/tex]
[tex]8 = d(0) - 1.5(6)[/tex]
[tex]d(0) = 17[/tex]
Then
[tex]d(t) = 17 - 1.5t[/tex]

find the sum of all possible four digit numbers that can be formed using the digits 2,4,5,6,7 and 8 with no repeated digits
Answer:
2133120
Step-by-step explanation:
using 6 given digits, lets create a 4 digit number:
to choose the first number, you have 6 options. to choose the second number we have 5 options left. for the third number we have 4 options left. and for the fourth number, we have 3 options left.
6*5*4*3 = 360
with no repeats, 360 numbers can be formed.
this means that each number will occur 60 times each (360/6 digits)
so to find the sum:
60*(2+4+5+6+7+8) = 1920
but, we have one more thing:
In the thousands place, our sum of digits is multiplied by 1000; in the 100’s place, by 100; in the ten’s place, by 10; and in the one’s place, by 1. so:
1920(1000+100+10+1) = 1920*1111 = 2133120
F(x) =2x-1 what is the value of f(x) when x = -1
Answer:
f(x) = -3 when x = -1
Step-by-step explanation:
Let's go through this!
So our equation is f(x) = 2x - 1
we are asked for the value of f(x) when x = -1
Let's consider this, the f(x) value is the y value
and the x value in f(x) is the x value
So when x = -1
what is the y value?
we can use the equation to subsitute -1 into x and solve for f(x)
f(x) = 2(-1)-1
f(x) = -3
Our answer is -3

I need a equation written for this pleeeeeaaaassse! The constant of proportionality is 2.
but I need an equation for this, I have an attachment for you to help. g= c is not correct sorry.
It sounds like your teacher wants g = 2c as the answer. The constant of proportionality simply tells us what to multiply the input variable by, to get the output variable.
It's similar to saying y = 2x, but we use c in place of x and use g in place of y.
