Let x be the number of digits in begin math size 16px style 2 to the power of 2001 end style when calculated. Let y be the number of digits in begin math size 16px style 5 to the power of 2001 end style when calculated. Find the sum of x and y

2002

Step-by-step explanation:

The number of digits in a number is the ceil value of the base-ten logarithm of the number (ceil value means rounding up).

When

When

Note that the sum x + y could be derived by finding the number of digits in

The number of zeros in is 2001. Including the 1 in leftmost digit position gives 2001 + 1 = 2002

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
