p=A/(1+rt) for r pls help me

Answers

The solution of the equation P = A/(1 + rt) for r is r = (A/P - 1)/t

How to solve the equation for r?

The equation is given as

P = A/(1 + rt)

Multiply both sides of the equation by (1 + rt)

So, we have

P(1 + rt) - A

Divide both sides by P

So, we have

1 + rt = A/P

Subtract 1 from both sides

rt = A/P - 1

Divide by t

r = (A/P - 1)/t

Hence, the solution of the equation P = A/(1 + rt) for r is r = (A/P - 1)/t

Six more than the product of a number and 4 is equal to 7. Use the variable b for the unknown number

Answers

The value of the unknown number b is 1/4.

What is substitution ?

Substitution is putting a specific value in a given variable.

According to the given question Six more than the product of a number and 4 is equal to 7 and we have to use b for the unknown number.

7 is 6 more than the product of 4 and b which can be numerically expressed as

7 = 6 + 4b...(i)

7 - 6 = 4b.

1 = 4b.

b = 1/4.

To check if it is correct or not we will substitute the numerical value of b.

in eqn (i).

7 = 6 + 4b

7 = 6 + 4×1/4

7 = 6 + 1

7 = 7.

The “4” next to the “3” is the ten million place and is the key number that needs to round up or stay the same, depending on what we do with the 3.

The rule for rounding is if a number is 5 or bigger, the number next to it goes up. If the number is 4 or smaller, the number does not round up.

Assume running consumes 111 Calories per mile. If you run 7-minute miles, what is your average power output, in watts?

Answers

By changing units from calories per minute to watts, we conclude that your power output is 1.11 Watts.

How to get the average power output?

Power is the ratio between energy consumed and the time in which it was consumed.

Here we know that you consume 111 calories per mile, and you run a mile in 7 minutes, then your power is:

P = (111 cal)/(7 min) = 15.86 cal/min

Now, we know that:

1 watt = 14.33 cal/min

Then we can rewrite our power as:

P = 15.86 cal/min = (15.86/14.33) W = 1.11 W

Your power output is 1.11 watts.

Answers

The strength ratio of each sports drink is 4:3.

What is ratio ?

Ratio can be defined as comparison of two or more similar quantities.

According to the given question Maria uses 2/3 cup of powdered mix for every 2 gallons of water.

Therefore the no. of cups of powdered mix per gallon in Maria's sports drink is

= (2/3)÷2

= (2/3)×(1/2)

= 2/6.

= 1/3 cups per gallon of sport drink.

In case of Franco the no. of cups of mix in his sport drink per gallon is

=(5/4)÷5

= 5/4×1/5

= 5/20

= 1/4 cups per gallon of sport drink.

∴ The strength of each sport drink is

= 1/3:1/4

= 12/3:12/4 ( LCM of 3,4 is 12 to remove the fractions)

The class width is solved to be 13lower class limits = 13, 26, 39, 52, 65, 78, 91upper class limits = 25, 38, 51, 64, 77, 90, 94

How to find the class width, the lower class limits, and the upper class limits

Given data

minimum equals 13, maximum equals 94, 6 classes

The class width

= ( maximum - minimum ) / 6

= ( 94 - 13 ) / 6

= 13.5

The class width is solved to be 13

lower class limits = 13, 26, 39, 52, 65, 78, 91

Upper class limits

The upper class limit is gotten from the lower class limit by reducing one from the class width to get 13 - 1 = 12. This value is added to the lower class limits to get the upper class limits.

What was the overall percent increase in the stadium capacity between 1920 and 2000

The overall percent increase in the stadium capacity between 1920 and 2000 considering the capacity was "x" in 1920 and "y" in 2000 is [tex][\frac{(y-x)}{x}*100][/tex].

As per the question statement, we are required to calculate the overall percent increase in the stadium capacity between the time period of 1920 and 2000. But no data about the stadium capacity is mentioned in the question statement. Hence, we will assume the capacity was "x" in 1920 and "y" in 2000. Assigning two variables to solve the question produces a generalized form of our required answer, in which, we can substitute any data to get the desired output.

Since Percentage change is calculated as

[{(Change from original)/(Original Value)}*100],

Our change in seating capacity of the stadium in 2000 from the year 1920 is [tex](y-x)[/tex] and original value being "x",

Overall percent increase in the stadium capacity between 1920 and 2000 is [tex][\frac{(y-x)}{x}*100][/tex].

Answers

Using the normal distribution, the 75th percentile for a 10 month-old girl is 74 centimeters.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 72, \sigma = 3[/tex]

The 75th percentile is X when Z = 0.675, hence:

0.675 = (X - 72)/3

X - 72 = 3 x 0.675

X = 74.

Answers

The change in temperature over the 10 hours using a mathematical operation, is 12℉.

What is a mathematical operation?

A mathematical operation uses input values (variables, numbers, mathematical operators, and operands) to determine an output value.

Some of the mathematical operators include addition, subtraction, division, and multiplication.

For instance, we can subtract the temperature in New Crampton at 6 A.M. from the temperature at 4 P.M. to determine the temperature change.

Data and Calculations:

The temperature at 6 A.M. in New Crampton = 64℉

The temperature at 4 P.M in the same city = 76℉

Change in temperature over 10 hours = 12℉ (76℉ - 64℉)

Thus, the change in temperature over the 10 hours using a mathematical operation, is 12℉.

Answers

Value of x is 6.2 cm when x is the radius of cone.

What is Volume of cone?

The amount of space occupied by a cone is referred to as the volume of a cone. The volume of the cone depends on the base radius of the cone and the height of the cone. It can also be expressed in terms of its slant height wherever necessary.

Volume of cone formula, V= 1/3*[tex]\pi[/tex]*r∧2*h

given,

Height h= 2x

radius = x

Volume V= 500cm3

V= 1/3*[tex]\pi[/tex]*r∧2*h

500 = 1/3 *22/7*x2*2x

x∧3 = 5*3*5*5*2*2*7/11*4

x∧3 = 5*3*5*5*7/11

x = ∛(5*3*5*5*7/11)

x = 5(∛21/11)

x = 6.2 cm

Therefore, the radius of the cone x is 6.2 cm
