Answer:
6^8
Step-by-step explanation:
6^4 * 6^4
We know that a^b * a^c = a^(b+c)
6^4 * 6^4 = 6^(4+4) = 6^8
Real number: -6 (for it is a constant)
Imaginary number is 2 & <em>i</em> (for it does not technically exist).
hope this helps
Answer:
The burgers cost $2.50 and the cookies cost $1.25.
Step-by-step explanation:
Let b represent burgers and c represent cookies.
2b + 2c = 7.50
4b + 3c = 13.75
<u><em>Step 1:</em></u> Use one of the two equations and isolate one of the variables.
2b + 2c = 7.50
- 2c -2c
b = - c
b = 3.75 - c
<u><em>Step 2:</em></u> Plug what you get for b into the second equation.
4(3.75 - c) + 3c = 13.75
15 - 4c + 3c = 13.75
15 - 1c = 13.75
<u><em>Step 3:</em></u> Isolate the variable and solve for c.
15 - 1c = 13.75
-15 -15
c =
c = 1.25 ← <em>price for cookies</em>
<u><em>Step 4:</em></u> Plug in what you have for c into one of the previous equations and solve for b.
2b + 2(1.25) = 7.50
2b + 2.50 = 7.50
- 2.50 -2.50
b =
b = 2.50 ← <em>price for burgers </em>
Now you know the cost of each item:
The burgers cost $2.50 and the cookies cost $1.25.
Answer:
14 miles.
Step-by-step explanation:
The First street, the Main street, and the Oak street forms a right triangle and the angle between the First street and the Oak street is x such that, tan x = 7/5. {Given}
The distance from the intersection point of the First street and the Main street to Oak street along the First street is 10 miles and we have to calculate the distance (d) of Oak street from the same intersection point along the Main street.
Now, using trigonometry on the above mentioned right triangle
⇒ d = 14 miles. (Answer)
