The cake slice with 15m due west and 15m due north is closer
What is distance?Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.Distance is how far apart objects are.Here , the slice of cake is 20m due east and then 10 m due south.
consider it as triangle ABC.
Required Displacement can be calculated by Pythagoras theorem -
AC = √ ( AB )² + ( BC )²
By substitution,
⇒ AC = √ ( 20 )² + ( 10 )²
⇒ AC = √ ( 400 + 100 )
Simplifying this equation, we get
⇒ AC = √500
⇒ AC = 10 √5
⇒ AC = 22.56
Thus , The cake slice is 22.56 m far away.
Here another slice of cake is 15m due west and 15m due north.
consider it as a triangle DEF.
Therefore,
⇒ DF = √ ( DE )² + ( EF )²
By substitution,
⇒ DF = √ ( 15 )² + ( 15 )²
Simplifying this equation, we get
⇒ DF = √ ( 225 + 225 )
⇒ DF = √ 450
⇒ DF = 15 √2
⇒ DF = 21.21
Thus the cake slice is 21.21 m far away.
Therefore this slice is closer.

I thought of a three digit number. Each digit i the quare of the digit to the right. What i my number
The three digit number you thought of is 111.
We now have:
According to the question:
N = a*100 + b*10 + c.
where:
b = c^2
a = b^2.
Let's now assign values to c. (here we can start with zero).
If c = 0, then b = 02 = 0 and a = 02 = 0 are the results.
Then N = 0*100 + 0*10 + 0 = 0 (this is not a 3-digit number) is the expression
If c = 1, then b = 12 = 1, then a = 12, and so on.
N = 1*100 + 1*10 + 1 = 111
If c = 2, then b = 2 2 4 a = 4 2 16 will follow.
111 is the only viable choice in this case.

The ∠3+ ∠1 = 90°. in the given figure are the same just using the properties of Vertically angles.
What is Vertically opposed angles?
Two lines intersecting at a point create vertical angles. Every time they are on an equal footing. Alternatively stated, four angles are created anytime two lines cross or intersect. Two opposed angles are equal and are referred to as vertical angles, as we can see. Due to their position opposite one another, they are also known as "Vertically opposed angles."
Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. The equality of the vertically opposed angles has been established.
∠1 and ∠2 are vertical angles, which means ,
∠1 =∠2
Given in the question is ∠3+ ∠2 = 90
As both ∠1 and ∠2 are the same so we can write ∠3+ ∠1 = 90°.

The percentage error of Bob’s measurement to the nearest tenth of a percent is 3.87%
The percentage error is The difference between the estimated value and the actual value in relation to the actual value is given as a percentage. Analyst use this formula to determine how big is the error in a relation to true value.
Here, given that
The experimental volume of liquid is 18.8 ml, and the actual volume of liquid is 18.1 ml
i.e. exprimental volume=18.8 mL
and, actual volume=18.1 mL
Now, we will calculate the percentage error
So,
percentage error=((Exprimental value-Actual value)/(Actual value))∙100
percntage error=((18.8-18.1))/18.1∙100
percentage error=0.7/18.1∙100
percentage error=0.0387∙100
percentage error=3.87%
Thus,
We got percentage error of 3.87% in measurement

The janitor at a school discovered a leak in a pipe. The janitor found that it was leaking at a rate of 12 f oz per minute. How fast was the pipe leaking in gallons per hour?
Answer:
5.625 gallons are being leaked per hour.
Step-by-step explanation:
Since every fluid ounce = 0.0078125 of a gallon,
0.0078125 x 12 (the amount of fluid ounces leaked per minute) = 0.09375
Since 0.09375 is the number of gallons leaked per minute, we have to multiply by 60 (because an hour is 60 minutes long).
12 x 60 = 720 (the number of fluid ounces leaked per minute)
0.09375 x 60 = 5.625 (the number of gallons are being leaked per hour)

What's proportionality?
Suppose there are two amounts. Proportionality indicates that if there's a change in the value of one number, the value of other number also changes but maintaining a constant ratio
Proportionality can be direct or inverse
Direct proportion
Two amounts are said to be in direct proportion if on increasing the value of one number, the value of other number also increases and vice versa.
For illustration cost of a commodity and volume of a commodity are in direct proportion
Inverse proportion
Two amounts are said to be in inverse proportion if on increases the value of one number, the value of other volume diminishes and vice versa.
For illustration Number of men and number of days taken by those men to complete a job

Victoria deposited $5000 Into a savings account that earns an annual simple interest rate of 0.3%. To the nearest tenth of a year, how long will it take for the account to reach $5500?
? year(s)
The account will reach $5500 after approximately 33.3 years have passed.
The simple interest formula is I = P x r x t, where I is the interest earned, P is the principal (the initial amount of money deposited), r is the annual interest rate, and t is the time in years.
You can rearrange this formula to solve for t: t = I / (P x r).
In this case, I = $500 (the difference between the final balance and the initial balance), P = $5000 (the initial amount deposited), and r = 0.3% (the annual interest rate).
Plugging these values into the formula, we get:
t = $500 / ($5000 x 0.3%)
t = $500 / ($5000 x 0.003)
t = $500 / $15
t = 33.333...
