Answer:

The total cost of the tablet is $840

Step-by-step explanation:

Here, we want to calculate the total cost

Let the total cost be $x

From the ratio, the total ratio is 3 + 4 + 1 = 8

so,;

3/8 * x = 315

3x = 8 * 315

x = 8/3 * 315

x = 8 * 103

x = 840

Answer:

In this case, you can simply treat the > sign like an = sign.  The only time you would need to worry about is when multiplying or dividing by negative numbers.

2x + 3 > 13

2x + 3 - 3 > 13 - 3

2x > 10

2x / 2 > 10 / 2

x > 5

Answer: 1620 gallons of water

Step-by-step explanation:

Let the water that is in the tank when the tank is at full capacity be represented by x.

Therefore, 40% of x = 648

40% × x = 648

40/100 × x = 648

0.4 × x = 648

0.4x = 648

x = 648/0.4

x = 1620

The answer is 1620 gallons

Answer:

The estimate is not correct?

Step-by-step explanation:

Given data

Area of wall = 18*8

=144ft^2

=4*144

=576ft^2

Area of doors

=3*7

=21ft^2

=2*21

=42ft^2

Area of window

=3*5

=15ft^2

Hence the total surface area of the room

=576-42-15

=519ft^2

The amount of paint needed= 519/300= 1.73

Approximately 2 gallons

We are told that 1 gallon will cover 300ft^2

Hence 3 gallons will cover 300*3= 900ft^2

Therefore the painter overestimated the amount of paint needed

As 2 gallons will do the job

Step-by-step explanation:

The required time for Lydia's account to reach $210,100 is 13.9 years.

Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.

First, convert R as a percent to r as a decimal

r = R/100

r = 6.7/100

r = 0.067 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(210,100/83,000) / ( 12 × [ln(1 + 0.067/12)] )

t = ln(210,100/83,000) / ( 12 × [ln(1 + 0.0055)] )

t = 13.9 years

Thus, the required time for Lydia's account to reach $210,100 is 13.9 years.

Answer:

The Mean Absolute Deviation (MAD) of a set of data is the average distance between each data value and the mean. The mean absolute deviation is the "average" of the "positive distances" of each point from the mean. The larger the MAD, the greater variability there is in the data (the data is more spread out).

I'm a little rusty on exponential rates, but I hope this helps!

The decay factor for the car will be equal to 0.925 or 92.5%

Powers can simply be expressed in concise form using exponential expressions. The exponent shows how many times the base has been multiplied. Since 2 is the "base" and 5 is the "exponent," it can be written as 2 x 2x 2 x 2=25 for the number 32. This phrase should be understood as "two to the fifth power."

Given that Ed's new car has a value of $23,500, it is expected to depreciate at a rate of 7.5% per year.

The decay factor will be calculated as,

[tex]y=a(1-b)^x[/tex]

b is 7.5%=0.075

Decay factor = 1-0.075

Decay factor = 0.925

Answer:

120

Step-by-step explanation:

First we can find the value of each exterior angle

The sum  of the exterior angles is 360

because a hexagon has 6 congruent exterior angles we divide 360 by 6

360/6=60 so each exterior angle is equal to 60 degrees

the exterior angle and interior angles of any regular polygon are supplementary angles ( meaning the sum of the two is 180) so to calculate the interior angle we subtract 60 from 180

180-60=120 so each measure of the interior angle of a hexagon is 120 degrees
