I am assuming from What I have found is that a is the base , b is angle between a and x and x is the hypotenuse . 
So we know that 
cos θ =base/hypotenuse 
here θ = 3Ď€/8 =67.5 degree 
cos 67.5 =0.38268 
so  
0.38268=a/x 
x=25/0.38268 
x=65.32873

Express 2.41 x 10/4 in a standard form.
kakasveta [241]

The number written in standard form is 24100

Step-by-step explanation:

An object is said to be written in scientific notation when it is written in the following form:

m\cdot 10^n

where

m is the coefficient

n is the exponent of the power of ten

The number can be rewritten in standard form by writing the coefficient and then moving to the right (or to the left) the decimal point by n positions if n is positive (or negative).

In this problem, the number is

2.41\cdot 10^4

So we have

m = 2.41

n = 4

Therefore, we have to write 2.41 and then move the decimal point 4 positions to the right: so we get

2.41\cdot 10^4 = 24100

Luis wants to buy a skateboard that usually sells for $79.74. All merchandise is discounted by 12%. What is the total cost of th
eduard

Answer:

75.26

Step-by-step explanation:

Most sales taxes work by not being calculated until cash in some form changes hands. So you take the discount first and then you add the sales tax on the new amount.

Take the discount first

Original cost = 79.74

Discount amount = 79.74 * 12% = 79.74 * 12/100 = 9.57

New price = 79.74 - 9.57 = 70.17

Now you are ready to add on the sales tax

70.17 * 7.25/100 = 5.09

The total is 70.17 + 5.09 = 75.26
