Issey's current location is the Lincoln Memorial. She uses her smartphone to look up walking directions to the Jefferson Memorial. She walks 1/2 mile every 1/8 hour. If the distance between the 2 memorials is 1 1/5 miles, it will take Issey how many minutes to walk from the Lincoln Memorial to the Jefferson Memorial.
a. 18 minutes
b. 24 minutes
c. 36 minutes
d. 72 minutes
To find out how long it will take Issey to walk from the Lincoln Memorial to the Jefferson Memorial, we need to divide the total distance by the distance she covers in one hour, and then convert the result to minutes.
First, let's convert Issey's walking speed to miles per hour:
1/2 mile every 1/8 hour = 4 miles per hour
Now we can calculate the time it will take Issey to walk the 1 1/5 miles:
Time = Distance ÷ Speed
Time = 1 1/5 miles ÷ 4 miles per hour
Time = 0.3 hours
Finally, let's convert this to minutes:
0.3 hours x 60 minutes per hour = 18 minutes
Therefore, it will take Issey 18 minutes to walk from the Lincoln Memorial to the Jefferson Memorial.
It will take Issey 288 minutes to walk from the Lincoln Memorial to the Jefferson Memorial.
Explanation:To find out how long it will take Issey to walk from the Lincoln Memorial to the Jefferson Memorial, we can divide the total distance by the walking speed. Issey walks 1/2 mile every 1/8 hour, which is equivalent to 4/8 miles per hour or 1/4 miles per hour. The distance between the two memorials is 1 1/5 miles, which is the same as 6/5 miles. To find the time it takes, we divide the distance by the speed: (6/5) / (1/4) = 24/5 = 4.8 hours. To convert this to minutes, we multiply by 60: 4.8 * 60 = 288 minutes.

What is the smallest number by which 256 may be divided so that the quotient is perfect cube?
(A) 2 (B) 3 (C) 4
Help!
Answer: 4
Step-by-step explanation:
The prime factorisation is 2x2x2x2x2x2x2x2
We have to make triplets of the prime factorisation which gives us:
(2x2x2)x(2x2x2)x2x2
2x2 is left so we divide 256 by 2x2 which equals 4
let's try to divide 256 by 4:
256/4 = 64
The cube root of 64 is 4
64 = (4)³ so it makes a perfect cube

Given the inequality 5(n − 4) < 4(n + 15), determine which integer makes the inequality false.
S:{80}

Answer:
-9
Step-by-step explanation:
5(-9-4)
5(-13)
-65
4(-9+15)
4(6)
24
-65<24 so -9 is false because -65 is not smaller than 24
The solution is Option A.
The value of n which makes the inequality 5 ( n − 4 ) < 4 ( n + 15 ) false is when n = 80
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is given by
5 ( n − 4 ) < 4 ( n + 15 )
Now , on substituting the value of n as 80 in the inequality equation , we get
5 ( n − 4 ) < 4 ( n + 15 )
when n = 80
5 ( 80 - 4 ) < 4 ( 80 + 15 )
5 ( 76 ) < 4 ( 95 )
380 = 380
So , the inequality will become false as the two sides of the equation will result in value 380 when n = 80
Hence ,
The value of n = 80 in the inequality equation 5 ( n − 4 ) < 4 ( n + 15 ) will make it false

Step-by-step explanation:
Fred the ant is on the real number line, and Fred is trying to get to the point 0. If Fred is at 1, then on the next step, Fred moves to either 0 or 2 with equal probability. If Fred is at 2, then on the next step, Fred always moves to 1. Let e_1 be expected number of steps Fred takes to get to 0, given that Fred starts at the point 1. Similarly, let e_2 be expected number of steps Fred takes to get to 0, given that Fred starts at the point 2. Determine the ordered pair (e_1,e_2). Answer is NOT (2, 3)
Answer:
The ordered pair (e₁, e₂) is (6, 8).
Step-by-step explanation:
Consider the pathway attached below.
Consider that Fred is at 1.It is provided that Fred moves to either 0 or 2 with equal probability, i.e. 0.50.
e₁ : 1 3 5 7 ...
P (e₁) : 0.50 0.50² 0.50³ 0.50⁴ ...
The expected number of steps Fred takes to get to 0 if he is at 1 is:
\(e_{1}=(1\times 0.50)+(3\times 0.50^{2})+(5\times 0.50^{3})+(7\times 0.50^{4})+...\\\\\)
The sum series e₁ is an AGP.
The sum of infinite AGP is:\(\frac{a}{1-r}+\frac{dr}{(1-r)^{2}}\)
Then the value of e₁ is:
\(e_{1}=\frac{1}{(1-0.50)}+\frac{2\times 0.50}{(1-0.50)^{2}}\\\\=2+4\\\\=6\)
Consider that Fred is at 2.It is provided that Fred always moves to 1 if he at step 2.
e₂ : 2 4 6 8 ...
P (e₂) : 0.50 0.50² 0.50³ 0.50⁴ ...
The expected number of steps Fred takes to get to 0 if he is at 2 is:
\(e_{2}=(2\times 0.50)+(4\times 0.50^{2})+(6\times 0.50^{3})+(8\times 0.50^{4})+...\\\\\)
The sum series e₂ is an AGP.
The sum of infinite AGP is:\(\frac{a}{1-r}+\frac{dr}{(1-r)^{2}}\)
Then the value of e₂ is:
\(e_{1}=\frac{2}{(1-0.50)}+\frac{2\times 0.50}{(1-0.50)^{2}}\\\\=4+4\\\\=8\)
Thus, the ordered pair (e₁, e₂) is (6, 8).
Answer:
(3, 4)
Step-by-step explanation:
For e_1, there is first a 1/2 chance that Fred will go to point 0 on the first move, giving us an expected value of 1/2. Similarily, there is 1/4 chance that Fred will go to point 0 on the 3rd move, giving us an expected value of 3/4th moves. We continue, and we see that the expected value for the number of moves is this.
\(1/2 + 3/4 + 5/8 + 7/16 + 9/32 + 11/64 ...\)
This equation eventually equals to 3, so e_1 is equal to 3.
For e_2, it's just e_1 + 1, because Fred has to move to point 1 in the first place.

How far did I travel to reach my destination on each day of my three-day Trip?
a. On Day 1, after traveling 5/8 of the way to the first day's destination, I still had 15 miles left to go before reaching my first destination.
b. On Day 2, after traveling 18 miles, I still had 2/5 of that day's distance left to go before reaching my second destination.
c. On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.
The total distances you traveled to reach your destination on each day of your three-day trip are as follows:
a) Day 1 = 40 miles
b) Day 2 = 30 miles
c) Day 3 = 11 miles.
How the total distances are determined:The total distances are determined using proportions.
Proportion refers to the fractional value of the whole number or quantity.
a) Day 1:
The fractional distance traveled = ⁵/₈
The remaining distance to travel = 15 miles
15 miles = ³/₈ (1 - ⁵/₈)
Proportionately, the total distance = 40 miles (15 ÷ ³/₈)
b) Day 2:
The distance traveled = 18 miles
The remaining distance to travel = ²/₅
The distance traveled = ³/₅ (1 - ²/₅)
³/₅ = 18 miles
Proportionately, the total distance = 30 miles (18 ÷ ³/₅)
c) Day 3:
The distance traveled = ⁵/₁₁
The distance to travel = 6 miles
The distance to travel in fractions = ⁶/₁₁ (1 - ⁵/₁₁)
Proportionately, if 6 miles = ⁶/₁₁, the total distance = 11 miles (6 ÷ ⁶/₁₁)

What is the slope intercept equation of a line that has a slope of -2 and a y-intercept of (0, 3)
Answer:
y = -2 x +3
Step-by-step explanation:
If the slope must be "-2", then the slope intercept form of the line should look like;
y = m x + b
with the slope "m" = -2
That is:
y = -2 x + b
Now the constant "b" can be found using the info on the value of the y-intercept which is (0, 3), so when x = 0, the value of the y-coordinate must be 3. By imposing this condition into the equation, we can find the value of "b":
3 = -2 (0) + b
3 = b
Then the equation becomes:
y = -2 x +3

As we can see, they sell 2/5 as many white milks and chocolate milks. We can write this as the ratio 2:5. As you can see, we are given the total, which is 35. The total of the ratio in simplest form is 7 (2+5). As you can see, we have to multiply by 5 to get that 7 to 35. Therefore we multiply each part of the ratio by 5 to get our final answer. We can have w represent the white milks while c represents the chocolate milks.
w/c = 2/5*5/5=10/25

Brainlist for positive attitude and correct answer :D
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D
