<u>Answer</u>
2,268
<u>Explanation</u>
<u>
</u>
<u>By grouping 378 ca</u>n be written as,
378 = 300 + 70 + 8
6× 378 = 6 × (300 + 70 + 8)
= (6×300)
+ (6×70) + (6×8)
= 1800
+ 420 + 48
= 2,268
An augmented matrix for a system of equations is a matrix of numbers in which each row represents the constants from one equation. I think the answer is the elevation gain from the starting point to checkpoint 1 is 100 feet less than double the elevation gain from checkpoint 2 to the peak.
Answer:
22.36 mile.
Step-by-step explanation:
Please see attached photo for explanation.
In the attached photo, y is the distance between starting point and the end point.
Thus we can obtain the value of y by using the pythagoras theory as show below:
Note: y is the longest side other wise known as the Hypothenus.
y² = 10² + 20²
y² = 100 + 400
y² = 500
Take the square root of both side
y = √500
y = 22.36 mile
Therefore, the distance between the starting point and the end point is 22.36 mile
Answer:
Step-by-step explanation:
Answer:
3 days: 8 heads.
10 days: 1024 heads.
Step-by-step explanation:
If each time the hero cuts off all the heads, then the amount doubles each time. This can also be represented using powers of 2, with 2^n, where n is the number of days.
2^1 = 2, so two heads the first time he cuts it.
2^2 = 4, so four heads the second time he cuts it.
With three, 2^3 is 8 so there are 8 heads.
With ten, 2^10 is 1024 so there are 1024 heads.
