Answer:
16 km is the answer
Step-by-step explanation:
a (Colton to parents' house) = 12 km
b = ?
c (parents' house to grandparents' house) = 20 km
According to the Pythagoras theorem,
a² + b² = c²
12² + b² = 20²
144 + b² = 400
b² = 400 - 144
b² = 256
b = 16
∴ Colton is 16 km away from his grandparents' house.
Step-by-step Answer:
AN is height, so A is perpendicular to BC. (See image attached).
BN = 18
AN = 24
AC = 40
All as labeled.
ABN is a right triangle, with AB = sqrt(18^2+24^2)=sqrt(324+576)=30
ACN is a right triangle, with CN = sqrt(40^2-24^2)=sqrt(1600-576) = 32
=>
BC = BN + NC = 18 + 32 = 50
25 this is it I don’t know if u understand it because I don’t lol
Answer:
2.25 tons
Step-by-step explanation:
It is a conversion problem. The connection between ton and pound is in the following order:
1 pound = 0.0005 tons
By multiplying each side by 4500 we can easily find the answer of this problem:
4500 pounds = 2.25 tons

<h3>Matrix notation</h3>
From the question, we are to determine which entry in the given matrix represents 
NOTE: For any entry denoted as
, it represents the entry in the <em>m</em>-th row and <em>n</em>-th column.
Thus,
represents the entry in the 2nd row and 3rd column.
In the given image, the entry in the 2nd row and 3rd column is 5.
Hence, in the given image,
is 5. The correct option is the first option 5
