Distance: 7-(-3)=10 Midpoint: (7+(-3))=4/2=2 hahaha haha thats right
Answer:
33 1/3 L of the 40% solution, 16 2/3 L of the 25% solution
Step-by-step explanation:
Set up two equations...
Let x represent the number of Liters of the 40% solution
Let y represent the number of Liters of the 25% solution
We need 50 liters total, so
x + y = 50
and we need the 50 L to be 35% solution, so
0.4x = 0.25y = 0.35(50)
Solve the first equation for one variable...
x = 50 - y (subtract y from both sides in equation 1)
Now substitute that value into the second equation...
0.4(50 - y) + 0.25y = 17.5 (x becomes 50 - y, 0.35(50) = 17.5)
Now solve for y...
20 - 0.4y + 0.25y = 17.5
-0.15y = -2.5
y = 16.66666667
y = 16 2/3 L
So we need to plug that into the first equation to find 'x'
x + 16 2/3 = 50
x = 50 - 16 2/3
x = 33 1/3
Answer:
6π
Step-by-step explanation:
The period indicates after which time the sine wave repeats.
You divide 2π by the factor in front of your function variable. This is 1/3 for your function.
So 2π/(1/3) = 6π
It is 36 feet because 6 times 2 times 3 =36
Answer:
1.82
Step-by-step explanation:
Add the prices to get the subtotal:
Sweet Tea:
2.49 * 2 = 4.98
4.98 + 15.99 + 4.99 = $25.96
The subtotal is $25.96
The sale's tax in Miami is 7% (the base 6% for FL, and the extra 1% for Miami).
$25.96 * 0.07 = 1.817 ≈ 1.82
The tax should be 1.82.
Hope this helps.
