Answer:
∛(512)= 8
Step-by-step explanation:
∛(512)=∛(8³)= 8
512 = 2*256=2*2*128= 2*2*2*64 = (2*2*2)*8*8 = 8*8*8=8³
Answer:
The decimal 3.75 would be 3 75/100 as a mixed number.
Step-by-step explanation:
75/100 expressed in the simplest fraction is 3/4.
Answer:because it’s just reversed
Step-by-step explanation:
Quick answer Sin(570) = - 1/2
Comment
570 as an angle contains 1 complete revolution of the terminal arm. The terminal arm begins at the origin and the other (in this case swings around until it records 570° turning around the x axis in an anticlockwise direction.
Anticlockwise means going from 12 o'clock to 9 o'clock to 6 o'clock then 3 o'clock and back to 12 o'clock.
What is 570° (∅) degrees equivalent to?
We keep on subtracting 360 until we get a number between 0 and 360 inclusive.
Written this way 0 ≤∅≤360
570 - 360 = 210°
So we need to find the equivalent of 210°
Method
210° = 180° + 30°
This means that ∅ is 30° below the x axis in the 3rd quadrant.
Sin(30) = 1/2
In the third quadrant, the sine is minus. so
sin(210°) = - 1/2 <<<<<<< Answer
Boxers = b
Spaniels = s


Now you have two equations - one that tells you the number of boxers in relation to spaniels and one telling you the number of each breed in relation to the total number of dogs. Solve using substitution.

There are
6 spaniels.
