Dante is making a necklace with 18 rows of tiny beads in which the number of beads per row is given by the series 3 + 10 + 17 + 24 + ... a. Use summation notation to write the series. Explain what the numbers in the summation notation represent in this situation and how you found the expression used in the summation.. . b. Find the total number of beads in the necklace. Explain your method for finding the total number of beads.

Answers

Answer 1
Answer: The numbers represent an arithmetic progression. The difference between terms is d=7. S=a1+a2+...+an, a1=3 and an=a1+(n-1)×d=3+17×7=122 S=(a1+an)n/2=(3+122)×18/2=125×9=1125

Solve the equation and enter the value of x below X+40=59

Answers

Answer:

X = 19

Step-by-step explanation:

To solve the equation X + 40 = 59, we need to isolate the variable X on one side of the equation.

1. Start by subtracting 40 from both sides of the equation:

X + 40 - 40 = 59 - 40

This simplifies to:

X = 19

2. Therefore, the value of X that satisfies the equation is 19.

In summary, to solve the equation X + 40 = 59, you subtract 40 from both sides of the equation to isolate the variable X. This results in X = 19.

Ms. McDuffy bought 2 1/2 yards of fabric that cost $7.90 per yard. She also bought 3 3/4 yards of fabric that cost $9.96 per yard. What is the total cost of the fabric?

Answers

The total cost of the fabric is $57.1

What is unit rate?

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one.

Given that, Ms. McDuffy bought 2 1/2 yards of fabric that cost $7.90 per yard. She also bought 3 3/4 yards of fabric that cost $9.96 per yard

Cost of fabric with unit rate = $7.90

= $7.90 × 5/2 = $19.75

And, cost of fabric with unit rate = $9.96

= $9.96 × 15/4 = $37.35

Total cost = $37.35 +  $19.75 = $$57.1

Hence, the total cost of the fabric is $57.1
