Answer:
The distance from B to B' is 5 units
Step-by-step explanation:
we know that
A translation is a rigid transformation, that means, the size and the shape of the pre-image is the same that the size and the shape of the image after the translation
so
The distance AA' will be equal to the distance BB'
the formula to calculate the distance between two points is equal to

we have
A(1,5) and A'(-2,1)
substitute




therefore
The distance from B to B' is 5 units
69 and 83 hundredths
69.83 is the answer
Answer:
3 gallons.
Step-by-step explanation:
If you add three gallons of water to 1 gallon of antifreeze, then there are 4 gallons total. That means that 1/4 of the solution is antifreeze, and 1/4 is equal to 25%.
Step-by-step explanation:
An inscribed angle is half the arc angle.
m∠MNQ = 80°/2
m∠MNQ = 40°
The angle between two chords is the average of the arc angles.
m∠AMB = (80° + 85°) / 2
m∠AMB = 82.5°
Here's the equation:
2^2 + 5^2 = c^2
4 + 25 = C^2
c = 5.3851
