Answer:
89·98 mph
Step-by-step explanation:
First, we get the circumference of the tires:
Circumference = [tex]\pi[/tex] × (radius × 2)
Circumference = 3.142 × (1·5 × 2)
Circumference = 3·142 × 3
Circumference = 9·426 ft
The circumference of the tire is equal to one round.
1 round = 9·426 ft
840 rounds = ?
We cross multiply to get the length that the tires would cover in a minute
= 840 × 9·426
1
1 minute = 7917·84 ft
60 minutes = ?
60 × 7917·84
1
= 475070·4 ft
5280 feet = 1 mile
475070·4 feet = ?
475070·4 × 1
5280
475070·4 ÷ 5280 = speed of the car in mph
89·97545
Round this off to 2 decimal places...
= 89·98 mph

Kyle is buying a new car. The car can be driven 24.3 miles with one gallon of gas. The
gas tank can hold 15.3 gallons of gas.
Kyle wants to know how far he can travel on a full tank of
gas. Which method and
reasoning can Kyle use to find the distance he can travel in miles?
Answer:
im sure the answer is 371.79
Step-by-step explanation:
Answer:
Unitary method
Total distance = 371.79 miles
Step-by-step explanation:
We are given that Kyle is buying a new car.
The car driven in one gallon of a gas =24.3 miles
The gas tank holds=15.3 gallons
We have to find the method and reasoning can Kyle use to find the distance he can travel in miles.
We have to find the distance travel in 15.3 gallons of a gas
So , we are using unitary method .
Unitary method : When we want to find more than one units with the help of one unit by multiplying
Because we are finding in 15. 3 gallons which is more than one and we are given that in 1 gallon of a gas car travel 24. 3 miles
Total distance =
Hence, the distance Kyle can travel in 15.3 gallons of gas=371.79 miles
It takes a man 20 minutes longer to travel from his home to his place of business if he drives at a rate of 30 mph than if he drives at a rate of 40 mph. How many miles is his home from his place of business?
20 minutes = 1/3 hours
let the distance be S
recall that time taken = distance/velocity
so, the time taken when travelling at 30 mph is S/30
and the time taken when travelling at 40 mph is S/40
therefore
S/30 - S/40 = 1/3
multiply through by 120
4S - 3S = 40
S = 40
distance = 40 miles

Which of the following systems has an infinite number of solutions?
A. x+y=1 and x−y=1
B. x+y=1 and x+y=−1
C. x+y=1 and −x−y=−1
D. x+y=1 and x+y=2
Answer:
C. x+y = 1 and -x-y = -1
Step-by-step explanation:
Remember that if a system of equations has an infinite number of solutions, then the resulting equation from using the first step of the elimination method would have no variables and would be true.
1) Let's try canceling out the equations in option C, x+y =-1 and -x-y =-1. Add the two equations together. (Work shown in attached picture.)
2) All of the terms cancel out with each other, leaving only a true statement of 0 = 0. Thus, option C is the answer.

Given the functions f(x) = x² – 8 and g(x) = 4-x, determine the equation for the combined function
y=f(x) - g(x).
Answer:
[tex]y=x^2+x-12[/tex]
Step-by-step explanation:
f(x) = x² – 8 and g(x) = 4-x
y=f(x) - g(x)
y=(x² – 8) - (4-x)

Which of the following is equivalent to the complex number i^17
Answer:
Step-by-step explanation:
It’s a repeating pattern.
i² = -1
i³ =(i²)i = (-1)i = -i
i⁴ = i³i = -i² = 1
i⁵ = (i⁴)i = (1)i = i
i⁶ = i⁵i = i² = -1
...
i¹⁷ = i
The value for [tex]i^{17}[/tex] is i.
What is an imaginary number?An imaginary number is denoted by i.
The value of i is √-1.
We have,
i = √-1
i² = -1
i³ = (i²)i = (-1)i = -i
i⁴ = i³i = -i² = 1
i⁵ = (i⁴)i = (1)i = i
i⁶ = i⁵i = i² = -1
We see that,
If the power is an even number we get 1 and -1.
If the power is an odd number we get i and -i.
Thus,
i¹⁷ = i

9514 1404 393
Answer:
17 minutes 8.6 seconds (17 1/7 min)2 hours 51 minutes 26 seconds (2 h 51 3/7 min)Step-by-step explanation:
The relationship between time, speed, and distance is ...
time = distance/speed
__
a) For 1 km, the time in hours is ...
time = (1 km)/(3.5 km/h) = 1/3.5 h = 2/7 h
In minutes, that is ...
(60 min/h)(2/7 h) = 120/7 min = 17 1/7 min . . . . time for 1 km
__
b) The time for 10 km is 10 times the time for 1 km, so will be ...
(10)(2/7 h) = 20/7 h = 2 6/7 h
In hours and minutes, that is 2 hours and (6/7)(60 min) = 360/7 min = 51 3/7 min.
The time for 10 km is 2 hours 51 3/7 minutes.

The total price of the graphing calculator is $80.07.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Percentage is usually denoted by the symbol '%'.
Given that,
Original price of the graphing calculator = $83
There is a 15% off on the site on all orders over $50.
Price of the calculator will be 100 - 15 = 85% of the actual price.
Price of the graphing calculator after the discount = 85% × 83
= 0.85 × 83
= $70.55
Sales tax on the discounted price = 4.5%.
Price after adding sales tax = $70.55 + (4.5% × 70.55)
= $73.72475
There is a shipping fee of $6.35.
Total price = $73.72475 + $6.35
= $80.07475
Hence the total price is a. $80.07.
