A cell phone battery charges at a rate of 16% every thirty minutes. When initially plugged into the charger, a cell phone has 10% battery.


1.Write an equation relating the amount of time, measured in hours, it takes to charge a cell phone as a function of the battery charge.
2.Use complete sentences to describe the rate in which the battery charges in terms of the time that it is charging.

Answers

Answer 1

30 minutes is 1/2 an hour so 16 x 2 = 32 the phone charges at 32% per hour.

1. Multiply the number of hours by the rate and add the original 10% to that for total charge:

Y = 0.32h + 0.10

2. The phone charges at 16% every thirty minutes which is a half hour so you double the rate it charges to get the rate per hour. The phone charges at 32% per hour that it is charging.

Answer 2

The required equation relating the amount of times is Y = 0.32t+0.10.

A cell phone battery charges at a rate of 16% every thirty minutes. When initially plugged into the charger, a cell phone has 10% battery.

What is equation?

Equation can be defines. the relation in sentences transform into math expression.
Since battery already has 10% charge i.e. we have 0.10 of intercept
now rate  = slope = m
for 30 min rate is 16%, for 1 hr rate become 32% =
hence slope = 32% = 0.32
now put slope and intercept in equation y = mt + c
then,
y = 0.32t + 0.10
where t is time
so the required function is given be
F(t) =   0.32t + 0.10

Thus, the battery increases by 32% every hour. and required relation is F(t) =   0.32t + 0.10

A math teacher at George Washington Middle School asked boys in the 6th and 7th grades to report their shoe size. She used the results to create these histograms

Which conclusion best supported by the histograms?
A as boys get older, shoe sizes become more normally distributed with fewer large outliers.
B As boys get older, shoe size range, defined by the minimum and maximum, decreases
C As boys get older, shoe sizes increase and the distribution remains relatively unchanged.
D As boys get older, shoe size distribution becomes more spread with more large outliers

Answers

Answer:

As boys gets older, shoe sizes becomes more normally distributed with fewer large outliers.

Step-by-step explanation:

A visual analysi ls of the histogram distribution provided, we can observe that size distribution of 6 graders is positively skewed (right tailed) as outliers seems more to the right(large sizes). However, the second graph is balanced with a normal or symmetric distribution representing older age (7th graders). Hence, we can conclude that as the boys gets older, they attain normality in terms of their shoe sizes. And the outliers which are characterized by the first histogram having vanished or reduced.

Area of a triangle is Base × High ÷2

You want to start by finding the area of each individual section. Start with the rectangle, you would do Length x Width (LxW) so 4x12 = 48. Then you find the area of the triangle. The formula for this is h b/2 so b (base) divided by 2 and then you multiply that by h (height). In this equation that would be 5/2=2.5 x (3+4)= 2.5 x 7 = 17.5. The last thing to do is find the area of the half circle. You start with the area of a circle formula which is (pi)r^2 (I don’t have a pi symbole so I’m just writing pi) pi =3.14 and r (radius). In the equation we have 4 ft. That would be the diameter. To get the radius we just need to divide the diameter, which in this case is 4, by 2. (4/2) were left with 2. Then we just plug in our numbers and we have pi2^2. (3.14x2)^2 =12.566. This is the area of the whole circle but since we only have half a circle, we divid it by two. So we have 6.283. Now we just add all the areas we got together for the full area of the shape. 17.5 + 48 + 6.283 = 71.783.

Sharon is painting her house. she needs 5
gallons of brown paint for every 7 gallons of white paint.  How many gallons of white paint does she need if she already bought 14 gallons of brown paint?
A. 10 gallons
B. 19.6 gallons
C. 16 gallons
D. 25 gallons​

Answers

Answer:

19.6, B

Step-by-step explanation:

To solve, we need to figure out how many gallons of white paint she needs for every gallon of brown paint.

We are given this equation.

5 gallons of brown paint = 7 gallons of white paint

Divide both sides by 5.

1 gallon of brown paint = 7/5 gallons of white paint = 1.4 gallons of white paint

Now, using this, substitute 14 into the left side.

14 gallons of brown paint = 1.4 * 14 gallons of white paint

14 gallons of brown paint = 19.6 gallons of white paint

Thus, the answer is B, 19.6 gallons
