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.
Answer:
Step-by-step explanation:
I am solving this using Function Notation.
We are given:
While we are to find:
In Function Notation, replace all the "
" you see with the value you are given.
So, in this case,
Would become
Now we can solve.
Use PEMDAS; Parenthesis first;
Cross divide: 1 cancels 1, -4 ÷ 2 = -2
Hence, we are left with
Therefore, the value of x is -5
Answer:
E - 40°
Step-by-step explanation:
Angle O = 2 × y
{Angle at center is equal to twice the angle at circumference formed by the same arc}
O = 2 × 70°
O = 140°
x + 90° + 90° + O = 360°
{Sum of angles in a quadrilateral is equal to 360°}
x + 90° + 90° + 140° = 360°
x + 320° = 360°
x = 40°
Hi,
A is the answer as : -2+2 = 0 and 5 -5 = 0
The answer is 1680. To get this you do 8*7*6*5 because there are 8 options for the first character, and then you can repeat that for the second one with 7, 6, and 5
