Answer:
Step-by-step explanation:
Let two consecutive odd numbers
x, x+2
According to condition
X(x+2) = 899
x2 +2x -899=0
X2 +31x -29x -899=0
x(x+31) -29(x+31)=0
(x+31)(x-29)=0
X=-31 or x =29
Now,
X=29
X+2= 29+2 = 31
Two consecutive odd numbers is 29 and 31
2 ways to do this...
(1) 3.59 * 1.06 = 3.8054 rounds to 3.81
(2) 3.59 + 0.06(3.59) = 3.59 + 0.2154 = 3.8054 rounds to 3.81
Answer:
z=2
Step-by-step explanation:
60=-5(-6-3z)
60= 30+15z
60-30=15z
30/15=15z/15
2=z
Answer: The coefficients of binomial expansions are calculated using Pascal's triangle.
Using proportions, it is found that due to the smaller division of the exchange rate by the cost, the souvenir would be less expensive in Egypt.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The souvenir would be less expensive in the <u>country in which the division of the exchange rate by the cost is smaller</u>.
In Britain, the cost is of 17, with an exchange rate of 0.83, hence the cost in US dollars is:
c = 17/0.83 = $20.48.
In Egypt, the cost is of 288, with an exchange rate of 18, hence the cost in US dollars is:
c = 288/18 = $16.
16 < 20.48, hence the souvenir would be less expensive in Egypt.
