Step-by-step explanation:
Distance covered by Amy in one hour = 1/3 x 15 miles = 5 miles
Distance covered by John in one hour = 1/5 x 30 miles = 6miles
As a result, John would jog 1 mile (6-5) farther than Amy, the answer is A
Answer: John goes 1 mile further than Amy
Step-by-step explanation:
Figure out how far each person can go in an hour
Amy can go 1/3 of a mile in 1/15 of an hour- Multiple by 15 to see how far she can go in 1 hour
[tex]\frac{1}{3} *15= \frac{15}{3} = 5[/tex] so in 1 hour Amy can go 5 miles
John goes 1/5 of a mile in 1/30 of an hour- so multiple by 30 to see how far he goes in 1 hour
[tex]\frac{1}{5} * 30 = \frac{30}{5} = 6[/tex]
John goes 6 miles in an hour
So John goes 1 mile further than Amy (6-5)=1
In Eduardo's collection, the number of butterflies is 12 more than twice the number of moths. If there are x moths, choose the expression that represent the number of butterflies he has.
Answers
Answer:
y = 12 + 2x
Step-by-step explanation:
Given that :
Let number of butterflies = y
Number of moths = x
y = 12 more than twice the number of moths
y = 12 + 2x
Hence, the expression which relates the number of butterflies he has is :
y = 12 + 2x

What is the greatest common factor of 45x^3, 24x^2, and 16x?
Answers
Answer:
[tex]\huge\boxed{\sf GCF = x}[/tex]
Step-by-step explanation:
Firstly we'll factorize the terms:
45x³ = 3 * 3 * 5 * x * x * x
24x² = 2 * 2 * 2 * 3 * x * x
16x = 2 * 2 * 2 * 2 * x
The factor which is common in all three terms is:

Hence GCF = x

The St. Petersburg paradox goes as follows. A fair coin is tossed repeatedly until it comes up heads. If the first heads appears on the nth toss, you win $2 n . First, show that the expected monetary value of this game is infinite (the paradox is that no one would actually pay a huge amount to play this game). Second, consider a possible resolution of the paradox: suppose your utility for money is given by a log 2 x b where x is the number of dollars you have. Suppose you start with 0 dollars, what is the expected utility of this game

Answers
Answer:
800
Step-by-step explanation:
160 * 100% / 20% = 800
If 20% of a number is 160 then the original number is 800.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that 20% of number is 160
We need to find the original number.
Let the original number be x
Convert 20% to decimal value by dividing 20 with 100
20/100=0.2
Now multiply 0.2 with x which is equal to 160
0.2x=160
Divide both sides by 0.2
x=800
Hence, If 20% of a number is 160 then the original number is 800.

What is the distance between the points (5, 13) and (-8, -9) on a coordinate plane rounded to the nearest tenth unit?
Answers
Answer:
25.6
Step-by-step explanation:
Use the distance formula.
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\d = \sqrt{(-8 - 5)^2 + (-9-13)^2}\\d = \sqrt{(-13)^2 + (-22)^2}\\d = \sqrt{169 + 484}\\d = \sqrt{653}[/tex]
The distance between the points (5, 13) and (-8, -9) is 25.6 units after using the distance formula.
What is a distance formula?It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We have two points (5, 13) and (-8, -9)
[tex]\rm d=\sqrt{(-8-5)^2+(-9-13)^2}[/tex]
d = √(169+484)
d = 25.55 units ≈ 25.6 units
Thus, the distance between the points (5, 13) and (-8, -9) is 25.6 units after using the distance formula.
