Answer:
80°
Step-by-step explanation:
The sum of the measures of the acute angles in a right triangle is 90°. The sum of ratio measures in the ratio 8 : 1 is (8+1) = 9. Thus, each of those measures stands for 90°/9 = 10°. Then the angle ratio is ...
80° : 10° = 8 : 1
The measure of the largest acute angle in the triangle is ...
10° × 8 = 80°
The answer is 4, therefore she can grow 4 watermelon plants in her garden:).
I dont know if this is right but I got: (6x+1)/4
The total rental cost is $120.
Let x be the amount each person pays and y be the total cost. Our first equation would be
4x = y.
The second equation would be
6(x-10) = y.
Since these are set equal to the same variable, we can use substitution:
4x = 6(x-10)
Using the distributive property, we have
4x = 6*x - 6*10
4x = 6x-60
Subtract 4x from both sides:
0 = 2x-60
Add 60 to both sides;
60 = 2x
Divide both sides by 2:
30 = x
This means each person pays $30 (in the first equation). 4(30) = 120 for y.
With 4 people, each person pays $30; with 6 people, each person pays 30-10=20.
