Answer:
The value of T₂₀ - T₁₅ is <u>-20</u>.
Step-by-step explanation:
<u>Given</u> :
- >> If for an A.P, d = -4
<u>To</u><u> </u><u>Find</u> :
- >> T₂₀ - T₁₅
<u>Using Formula</u> :
General term of an A.P.
- >> Tₙ = nᵗʰ term
- >> a = first term
- >> n = no. of terms
- >> d = common difference
<u>Solution</u> :
Firstly finding the A.P of T₂₀ by substituting the values in the formula :
Hence, the value of T₂₀ is a + 19d.
Secondly, finding the A.P of T₁₅ by substituting the values in the formula :
Hence, the value of T₁₅ is a + 14d
Now, finding the difference between T₂₀ - T₁₅ :
Hence, the value of T₂₀ - T₁₅ is -20.
Answer:
<h2>125 tickets for an adult</h2><h2>and 175 tickets for a student</h2>Step-by-step explanation:
The fraction represents the number of women's magazines out of all the other magazines at the book store.
To find what percent of the magazines are women's magazines, we can turn into a percent.
To write a fraction as a percent in lowest terms, first remember that a percent is a ratio of a number to 100 so to write 26/64 as a percent, we need to find a fraction equivalent to 26/64 with 100 in the denominator. We can do this by setting up a proportion.
40% is the answer
