Answer:
Total distance = 30.3 units
Step-by-step explanation:
Coordinates for the location of Alanah, Mia, Teresa and Arena are,
Alanah → (2, 8)
Mia → (8, 16)
Teresa → (8, 2)
Arena → (14, 4)
Distance between two points 
and 
is given by the formula,
d = 
Distance between Alanah and Mia = 
= 
= 10 units
Distance between Mia and Teresa = 
= 14 units
Distance between Teresa and Arena = 
= 
= 6.3 units
Total distance of Alanah's trip to Arena = 10 + 14 + 6.3
= 30.3 units
Answer:
7+2x=4x 3=13
Step-by-step explanation:
Idk
Ok so here it is
natural numbers: counting numbers like 1,2,3,4,5...
whole numbers: counting numbesr and 0, so 0,1,2,3,4
integers: negative counting numbers and 0, so -3,-2,-1,0,1,2,3...
ratioal numbers, things that can be represented in a/b
percent means parts out of 100 so
x%=x/100
that is a ratioal number
negatives are integers
Answer:
BC ≈ 19.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = 
= 
= 
( multiply both sides by BC )
BC × cos71° = 6.3 ( divide both sides by cos71° )
BC = 
≈ 19.4 cm ( to 3 significant figures )
Answer:
x= 8
Step-by-step explanation:
Pythagoras' Theorem states that the square of the hypotenuse side (side opposite the right angle) is the sum of the squares of the other 2 sides.
Applying Pythagoras' Theorem,
x² +6²= 10²
Simplify:
x² +36= 100
x²= 100 -36
x²= 64
Square root both sides:
x= 8
