When Lucy left her house in the morning, her cell phone battery was partially charged. Lucy's phone lost battery life at a rate of 8% each hour and 3 hours after leaving her house, the battery had 16% remaining battery life. Write an equation for B , B, in terms of t , t, representing the charge remaining in Lucy's battery, as a percentage, t t hours after Lucy left her house.
Answer:
B = 40 - 8t
Step-by-step explanation:
Given that:
Rate at which battery life discharges = 8% per hour ;
Battery life left after 3 hours = 16%
t = hours after Lucy left hiuse
Equation B will be ;
Amount of charge before leaving home - (Discharge rate * number hours)
Amount of charge before leaving home :
Charge left after 3 hours + discharge rate * 3
16% + 8*3
16% + 24% = 40%
Hence,
B = 40 - 8t
Answer:
probably B = 40 - 8t

56 men can do a work in 42 days then how many men will do the same work in 14 days
Given : 56 men can do a work in 42 days .
To Find : In how many men will do the same work in 14 days .
Solution : We will use Unitary method here to solve the above problem . This is a case of inversely proportional that is when one will increase the other will decreases . Here if the number of men will increase then the number of days will decrease and vice - versa .
If in 42 days 56 men can do the work ,
Then in 1 day 42 × 56 men can do the work .
Then in 14 days , [tex]\sf \dfrac{42\times\cancel{56}}{\cancel{14}}[/tex] will do the work = 168 .
Hence 168 men will do the work in 14 days .

What is the midpoint
between (-2, -3) and
(1, 2)?
a) (-1,-)
b) (-:-)
c) (-1,-)
d) (-3,-)
Answer:
I think it's B
...........
Answer:
d
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (- 2, - 3) and (x₂, y₂ ) = (1, [tex]\frac{1}{2}[/tex] ), thus
midpoint = ( [tex]\frac{-2+1}{2}[/tex], [tex]\frac{-3+\frac{1}{2} }{2}[/tex] ) = ( [tex]\frac{-1}{2}[/tex], [tex]\frac{-3+\frac{1}{2} }{2}[/tex] ) = ( - [tex]\frac{1}{2}[/tex], [tex]\frac{-\frac{5}{2} }{2}[/tex] ) = ( - [tex]\frac{1}{2}[/tex], - [tex]\frac{5}{4}[/tex] ) → d

CAN SOMEONE PLEASE HELP ME ASAP PLEASEE ANYBODY LITERALLY ANYONE OUT THERE PLEASE. Determine m∠ABQ and determine m∠BCR.
Answer:
ABQ = 139
BCR is the same as QBC since they are alternate interior angles
BCR = 41
Step-by-step explanation:
CBQ and SCB are same side interior angles so they add to 180
2a-9 + 5a +14 = 180
Combine like terms
7a +5 = 180
Subtract 5 from each side
7a = 175
Divide by 7
7a/7 = 175/7
a = 25
ABQ is the same as SCB since they are corresponding angles so
ABQ = SCB = 5a+14 = 5*25+14 = 125+14 = 139
BCR is the same as QBC since they are alternate interior angles
BCR = QBC = 2a-9 = 2*25 -9 = 50-9 = 41
The measure of the sides of a
triangle are in the extended
ratio of 3:5:7. The perimeter
of the triangle is 45 in. What
are the measures of the three
sides?
a) 6, 16, 23
b) 8, 15, 22
c) 6,9,15
d) 3, 5, 7
e) 9, 15, 21
Answer:
e) 9, 15, 21
Step-by-step explanation:
First you multiply each number in the ratio by x and set it equal to the perimeter or 45 in this case.
3x + 5x + 7x = 45
Then you add the like terms and get
15x = 45
Solve for x
x = 3
Now multiply 3 by each number
3•3= 9
3•5= 15
3•7= 21

Noah’s scores for four Spanish quizzes are 70, 75, 83, and 80. What score must he get on the next quiz to achieve an average of at least 80?
Answer: 92
Step-by-step explanation:
Here's our set-up:
(70 + 75 + 80 + 83 + x) / 5 = 80
Simplify:
(308 + x) / 5 = 80
Multiply both sides by 5:
308 + x = 400
Subtract 308 from both sides:
x = 92
Answer:
92
Step-by-step explanation:
In order to get an 80 in 5 tests, he needs to accumulate 400 points.
If he accumulated 80+70+75+83 points, 308, he would need a 92 on the next test to get an 80 average.

The boutique's monthly sales when Jenny first began tracking the data is 4000
What is piecewise function?
A function which is defined by multiple sub-functions, each sub-function applying to a certain interval of the main function's domain (a sub-domain).
Given:
According to given function we can say that there x represent the number of month.
So, if jenny begin tracking the data then jenny spend 0 month on working
Thus, we will use the function
f(x)= 4000*(1.1)^x
f(x)= 4000*(1.1)^0
f(x)= 4000

An object that is projected straight downward with initial
velocity v feet per second travels a distance s = vt + 16t2,
where t = time in seconds. If Ramón is standing on a
balcony 84 feet above the ground and throws a penny
straight down with an initial velocity of 10 feet per second,
in how many seconds will it reach the ground?
A. 2 seconds
B. 3 seconds
C. 6 seconds
D. 8 seconds
Answer: 2 seconds
Step-by-step explanation:
An object take 2 seconds to reach to the ground. option A is correct.
An object that is projected straight downward with initial velocity v feet pee second.
s = vt + 16t2
s = 84 feet and v = 10
Velocity is ratio of displacement to the time.
We have equation.
s = vt + 16t2
Now, put s = 84 and v = 10
84 = 10t+16t2
8t2+10t-42=0
Taking roots of equation.
We get t = 2 and -21/8
Since time couldn't be negative.
So,
t = 2
Thus, An object take 2 seconds to reach to the ground.
