Combine like terms so add 4b and 15b together and add 7 and 3 together and then the answer would be 19b-10
Answer:
50
Step-by-step explanation:
x = √30² - 18² = √576 = 24
tan A = 18/24 = 3/4
∠A = ∠B
tan B = tan A = 24 / y = 3 / 4
y = (24 x 4) / 3 = 32
Z = y + 18 = 32 + 18 = 50
Quantity of cheerios cereal in the smaller box Hannaford sold = 9 ounces
Cost of nine ounces of cheerios cereal = $2.50
Cost of one ounce of cheerios cereal :


Cost of one ounce of cheerios cereal in the smaller box = $0.27
Quantity of cheerios cereal in the larger box Hannaford sold = 20 ounces
Cost of nine ounces of cheerios cereal = $3.79
Cost of one ounce of cheerios cereal :


Cost of one ounce of cheerios cereal in the larger box = $0.18
Difference in their cost per ounce :


Therefore, the difference in cost in dollars per ounce between the two sizes = $0.09
Answer:
Step-by-step explanation:
Before you can add or subtract fractions together, they need a common denominator. The least common denominator for ½ and ⅕ is 10.
The <em>approximate</em> price for an ornamental bookcase from Germany and with a cost of EUR 830 on November 26, 2019 is equal to 753.64 USD.
<h3>How to determine the price of a good in terms of a foreign currency</h3>
Herein we have an application of <em>direct proportionality</em> model, now described:
y = k · x (1)
Where:
- x - Cost of the bookcase in Germany, in euros.
- k - Currency exchange rate, in US dollars per euros.
- y - Cost of the bookcase in the United States, in US dollars.
If we know that x = 830 EUR and k = 0.908 USD/EUR, then the cost of the bookcase in the United States is:
y = (830 EUR) · (0.908 USD/EUR)
y = 753.64 USD
The <em>approximate</em> price for an ornamental bookcase from Germany and with a cost of EUR 830 on November 26, 2019 is equal to 753.64 USD.
