A truck like the one shown delivers a load of gasoline to a gas station 3 times a week. The storage tank at the gas station holds 9 loads of fuel. How much more gas does the storage tank hold than the truck.
The truck hauls 2,700 gallons.
Answer:
21,600 gallons
Step-by-step explanation:
The truck hauls 2,700 gallons.
Given :
A truck load of gasoline = 2700 gallons
Capacity of storage tank = 9 loads
Gallons of fuel which storage tank can take :
9 loads
1 load = 2700 gallons
9 * 2700 gallons
= 24300 gallons
Hence, the storage tank holds (9 - 1) = 8 more loads of gasoline than the truck :
24300 gallons - 2700 gallons = 21600 gallons

A patient has an illness that typically lasts about 24 hours. The temperature, T, in degrees Fahrenheit, of the patient t hours after the illness begins is given by:T(t) = -0.02t^2 +0.4968 +98.
a. When does the patient's temperature reach its maximum value
b. What is the patient's maximum temperature during illness
Step-by-step explanation:
Given that,
The temperature, T, in degrees Fahrenheit, of the patient t hours after the illness begins is given by:
[tex]T(t)=-0.02t^2 +0.4968 t+98[/tex] ...(1)
(a) We need to find when does the patient's temperature reach its maximum value.
For maximum value.
Put dT(t)/dt = 0
[tex]\dfrac{d(T(t)}{dt}=\dfrac{d}{dt}(-0.02t^2 +0.4968t +98)\\\\=-0.04t+0.4968\\\\-0.04t+0.4968=0\\\\t=12.42\ h[/tex]
(b) Put t = 12.42 in equation (1) :
[tex]T(12.42)=-0.02(12.42)^2 +0.4968 (12.42)+98\\\\=101.08^{\circ} F[/tex]
Hence, this is the required solution.

give you the new function n(x) = (x + 2)^3– 7?
A. n(x) = f(g(h(x)))
B. n(x) = g(f(h(x)))
C. n(x) = g(h(f(x)))
D. n(x) = h(f(g(x)))
E. n(x) = f(h(g(x)))
please help a girl is struggling❤️
Answer:
n(x) = g(f(h(x)))
Step-by-step explanation:
Given
[tex]f(x) = x^3[/tex]
[tex]g(x) = x-7[/tex]
[tex]h(x) = x + 2[/tex]
Required
Which function represents [tex]n(x) = (x + 2)^3 - 7[/tex]
Start by solving for f(h(x)):
Given that:
[tex]f(x) = x^3[/tex] and [tex]h(x) = x + 2[/tex]
Substitute x + 2 for the x in f(x)
[tex]f(h(x)) = (x + 2)^3[/tex]
Next, solve for g(f(h(x)))
Given that:
[tex]g(x) = x-7[/tex] and [tex]f(h(x)) = (x + 2)^3[/tex]
Substitute (x + 2)^3 for the x in g(x)
[tex]g(f(h(x))) = (x + 2)^3 - 7[/tex]
Recall that:
[tex]n(x) = (x + 2)^3 - 7[/tex]
Hence:
[tex]n(x) = g(f(h(x))) = (x + 2)^3 - 7[/tex]

What is the value of the expression when a = –5 and c = –1? Enter your answer in the box.
Answer:
-5a+-1c
Step-by-step explanation:
The value of Expression: 8a+ 16c is -56.
What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Given:
Expression: 8a+ 16c
We have the value a= -5 and c=-1
So, putting the values in the given expression as
8a+ 16c
= 8(-5)+ 16(-1)
= -40 - 16
= -56
Hence, the value is -56.

A car was driving for 4 hours and covered 224 miles. A high-speed train is ten times as fast as this car. Find the train's speed.
Answer:
The speed of the train is 560 MPH.
Step-by-step explanation:
The car's speed can be detemined by Distance / Time. This would mean we would have to do 224 / 4, which would equal 56.
Now, all we have to do is mulitply 56 by 10. This would equal 560.

Sergi says that 10% of a number will always be less than 20% of any other number. Complete one inequality to support Sergi’s claim and one to show that he is incorrect
Answer:
x × 0.1 < y × 0.2
x = 100, y = 10
Step-by-step explanation:
10% of a really large number can be bigger than 20% of a small number. 10% of 100 is 10. 20% of 10 is 2. 10 is bigger than 2 so Sergi's claim is false.

You are the operations manager for an airline and you are considering a higher fare level for passengers in aisle seats. How many randomly selected air passengers must you survey? Assume that you want to be 95% confident that the sample percentage is within 4.2 percentage points of the true population percentage.
Answer:
545 randomly selected air passengers must be surveyed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
Assume that you want to be 95% confident that the sample percentage is within 4.2 percentage points of the true population percentage.
We dont know the true proportion, so we use [tex]\pi = 0.5[/tex], which is when the largest sample size will be needed. We have to find n for which [tex]M = 0.042[/tex]. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.042 = 1.96\sqrt{\frac{0.5*0.5}{n}}[/tex]
[tex]0.042\sqrt{n} = 1.96*0.5[/tex]
[tex]\sqrt{n} = \frac{1.96*0.5}{0.042}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96*0.5}{0.042})^2[/tex]
[tex]n = 544.4[/tex]
