Answer:
If we want our ratio to stay the same (3 to 5), we'll need to pair a set of 3 blue tacks with every set of 5 red tacks. In a group of 50, we can make 10 groups of 5 red tacks, so we'll also need 10 groups of 3 blue tacks, which gives us a total of 30 blue tacks
Answer:
x > 7
(I think this is Right but not sure yet )
<span>So we need to find the solutions to the equation (x+6)y=9 so we can arrange them in pair (x,y). We simply plug in the numbers into the equation. First pair (-5,9), we get (-5+6)9=9 so 1=1 and that is true, so first pair works. Second pair: (-3+6)3=9 we get (3)3=9 and 9=9 so second pair also works. Third pair: (3+6)1=9 we get 9=9, also works. Fourth pair: (7+6)9=9 we get 13*9=9 and 117=9 which is false so the fourth pair can't be a solution for the equation. The correct answers are A, B and C.</span>
Answer:
40°, 80°, 120°, 120°
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 + 3 + 3 = 9 parts
The sum of the interior angles of a quadrilateral is 360°
Divide this by 9 to find the value of one part of the ratio.
360° ÷ 9 = 40° ← value of 1 part of the ratio
Then
2 parts = 2 × 40° = 80°
3 parts = 3 × 40° = 120°
The 4 angles are 40°, 80°, 120°, 120°
