Answer:
i just took the test its (4,1)
Step-by-step explanation:
It’s is greater it would only be equal if you multiplied it by 100
Let X = the number of pennies.
The number of nickels would be 2X
A penny is 0.01 and a nickel is 0.05
Now you have:
0.01x + 2(0.05x) = 8.80
Simplify:
0.01x + 0.10x = 8.80
Combine like terms:
0.11x = 8.80
Divide both sides by 0.11:
x = 8.80 / 0.11
x = 80
Pennies = X = 80 total pennies.
Nickels = 2x = 2 *80 = 160 nickels.
no the firm will not do the investment. because if the firm borrows the money & invest it in the project then the return will be 6% but the cost is 8%. so it will lose 2%.
it also should not invest his own money on the project to get get the 6% return. because he could have loan the money to someone else & get 8% return. therefore his opportunity cost of investing the money is greater than the return.
therefore he should not make the investment .
When finding the third side of a scalene triangle, use Law of Cosine with its formula
c^2 = A^2+B^2 - 2AB(cosC)
Now, you just have to input all your data in the formula,
c^2 = 6^2+11^2 - 2(6)(11)(cos40degrees)
c^2 = 36+121 - 2(6)(11)(cos40degrees)
c^2 = 36+121 - 2(6)(11)(0.77)
c^2 = 157 - 101.12
c^2 = 55.88
c = square root of 55.88
c = 7.48 ft
Length of EF is 7.48 ft
