CORRECT ANSWER GETS BRAINLIEST
kati45 [8]

Answer:

2.5

Step-by-step explanation:

t = 0.25d^{1/2}

Substitute d with 100

t = 0.25 x (100^{1/2})

A number to the half power is equal to the square root of a number.

Square root of 100 is 10: \sqrt{100} = 10

t = 0.25*10

t = 2.5

Hope this helps :)

Have an awesome day!

The sum of the finite arithmetic series of <span> 26 + 29 + 32 + 35 + 38 + 41 + 44 is 245. Arithmetic series is a sequence of number such that the difference between any term and the previous term is a constant number. When we sum a finite number of terms in the arithmetic series, we get the finite arithmetic series. </span>

Write the fraction in simplest form. (3/6) x (7/10)
mrs_skeptik [129]
Answer:
7/20
Explanation:
In order to do this, you must first simplify all the equations to the simplest forms. Do this by simplifying 3/6 to 1/2. We know this because 3 is half of 6, therefore it would reduce down to 1/2. 7/10 is already simplified; we know this because 7 is a prime number and can’t do down any further
Now, multiply the two fractions buy multiplying the numerators and denominations together. In other words, 1 x 7 is 7 so your numerator is 7, and 2 x 10 is 20 so your denominator is 20.
