Answer:
Amount of vinegar. 100% : 20 milliliters
Amount of Italian dressing: 140 milliliters
Step-by-step explanation:
Let's call A the amount of vinegar. 100%
Let's call B the amount of Italian dressing . 12% vinegar
The resulting mixture should have 23% vinegar, and 160 milliliters.
Then we know that the total amount of mixture will be:
Then the total amount of pure antifreeze in the mixture will be:
Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -1 and add it to the second equation:
+
--------------------------------------
We substitute the value of B into one of the two equations and solve for A.
X is 56 degrees
Because two of the sides are equal to 62 so 62*2 is 124 and since a triangle is equal to 180 degrees subtract it and you get x to be 56 degrees
Answer:
$10,603.20
Step-by-step explanation:
You can calculate the simple interest of the loan using the formula:
I = prt, where I = interest, p = principal amount, r = interest rate and t = time. Plugging in the values from the problem:
p = $7,050
r = 8.4% or 0.084
t = 6 years
I = (7050)(0.84)(6) = $3,553.20
To find the total cost of the boat, add the interest and the purchase price:
$7,525 + $3,553.20 = $11,078.20
3 feet= 1 yard
16*3= 48 feet.
47.52/48= 0.99
It will cost Brian $0.99 per foot.
Find the unit rate.
49.50/50= 0.99
No, it wouldn't. It would be the <em>same price
0.99=0.99 It doesn't matter which one Brian chose. </em>
I hope this helps!
