Answer:
1/4
Step-by-step explanation:
using the product-to sum formulas, this is
1/2 (cos(75+15) + cos(75-15))
<u>One correct inequality is </u>
1.19x≤10,
<u>
and the correct solution is</u>
x≤8.
Explanation:
Let x be the number of songs Jose downloads. Each song has a cost of $1.19; this would give the total amount spent as 1.19*x, or 1.19x.
He has at most $10 to spend. This means he can spend less than $10 or exactly $10; this gives us the inequality symbol ≤, which makes our complete inequality
1.19x ≤ 10.
To solve this, divide both sides by 1.19:
1.19x/1.19 ≤ 10/1.19
x ≤ 8.4.
Jose won't download a partial song, so we round this down to 8:
x≤8
Answer:
∠ AOC = 124°
Step-by-step explanation:
the 3 angles lie on a straight line and sum to 180°
sum the 3 angles and equate to 180
3x + 94 + x + 30 + 2x - 4 = 180
6x + 120 = 180 ( subtract 120 from both sides )
6x = 60 ( divide both sides by 6 )
x = 10
Then
∠ AOC = 3x + 94 = 3(10) + 94 = 30 + 94 = 124°
Answer: 15
Step-by-step explanation:
It's an Isosceles triangle meaning both sides are congruent (same)
So with that in mind we can make an equation making them equal to each other to find X.
3x = 5x - 30
Subtract 5x from both sides
-2x = -30
We can't have a negative x so we divide x by a negative
x = 15
