Answer:
<u>250</u>
Step-by-step explanation:
You can take the explicit formula and simply substitute the n value with 64:
-2 + 4 * (64 - 1)
-2 + 4 * (63)
-2 + 252
<u>250</u>
Answer:
Input of x when it is equal to (1,2,3,4,5) gave an output of 3, 9, 27,81 & 243 respectively.
Step-by-step explanation:
Step 1. Substitute for x (1,2,3,4,5) in the functions to solve for the output of y.
y=3^x
when x= 1
y=3¹ = 3
when x= 2
y=3² = 9
when x= 3
y=3³ = 27
when x= 4
y=3⁴ = 81
when x= 5
y=3 ^ 5 = 243.
Input of x when it is equal to (1,2,3,4,5) gave an output of 3, 9, 27,81 & 243 respectively.
This problem is simply asking us to add the weights which are presented as fractions. You can easily get the answer if you input them directly in a calculator. But I think the challenge here is to manually add fractions.
Let's add the two 1/4 lb weights because it is easier for they have a common denominator. Just simply add the numerators.
1/4 + 1/4 = 2/4
Then, add with this the fraction part of 2 1/5.
2/4 + 1/5 = ?
The least common denominator is 4*5 = 20. Then divide 20 with each denominator and multiply to their respective numerator.
2/4 + 1/5 = [(20/4 * 2) + (20/5 *1)]/20 = 14/20
14/20 is simplified to 7/10. Then add the whole number 2. <em>Therefore, the sum of all weights is 2 7/10 pounds.</em>
Answer: 2 : 7
Step-by-step explanation:
Number of boys = 4
Number of girls = 10
Total number of students = total number of boys + total number of girls ,that is
Total number of students = 4 + 10
= 14
Therefore , the ratio in the simplest form that compares number of boys to total number of students is given by
number of boys : total number of students , that is
4 : 14
which will be
2 : 7 in the simplest form
