Answer:

6. 12/13 7. 4/3

Step-by-step explanation:

6) cos = adj/hyp

opp ∠C = 5

adj ∠C = 36

hyp = 39

cosC = 36/39 = 12/13

7) tan = opp/adj

opp ∠C = 36

adj ∠C = 27

hyp = 45

tanX = 36/27 = 4/3

A silver chain has 100 links. Each link is made of thin silver wire and is in the shape of a circle of radius 2,5 cm. Find the v

Tamiku [17]

Number of links = 100

Shape of each link = Circle

Radius = 2.5

Area = πr²

= 3.14×2.5×2.5

= 19.625

Now for 100 links

19.625×100

1962.5Cm²

Cost = 1962.5 × 0.06

= $117.75

In an average year, the American chemical industry produces more than 9.5 million metric tons of sodium carbonate. Over half of

Phoenix [80]

Answer:

2.09 × 10¹⁰ pounds

Step-by-step explanation:

The American chemical industry produces more than 9.5 million metric tons of sodium carbonate.

in this problem we have to calculate the amount in pounds of sodium carbonate are produced annually.

so we will convert the amount of 9.5 million metric tons to pounds.

Since in 1 metric ton = 2204.62 pounds

Hence, 9,500,000 metric ton = 2204.62 × 9,500,000

= 20943890000 pounds

= 2.09 × 10¹⁰ pounds

2.09 × 10¹⁰ pounds of sodium carbonate are produced annually.

The license plates on all karts in MarioLand contain three numbers followed by three letters. If you know that the MarioLand num

iogann1982 [59]

Answer:

It can be created 1575 license plated with at least one three-piece palindrome.

Step-by-step explanation:

If a license plates has at least one three-piece palindrome, we have the following cases:

1. The license plate just has a palindrome in the three numbers: The number license plates for this case can be calculated using the rule of multiplication as:

5 * 5 * 1 * 3 * 3 * 2 = 450

1st Number 2nd 3rd 1st Letter 2nd 3rd

For have a palindrome in the numbers, the first and the 3rd number need to be the same. So, we have 5 digits for the first and the 2nd Number and one digit for the 3rd Number.

On the other hand, if the palindrome is just in the numbers, the 3rd letter need to be different from the 1st. So we have 3 options for the 1st and the 2nd letter and 2 options for the 3rd letter.

At the same way, we can calculated the number of license plates for the other cases:

2. The license plate just has a palindrome in the three letters:

5 * 5 * 4 * 3 * 3 * 1 = 900

1st Number 2nd 3rd 1st Letter 2nd 3rd

3. The license plate has a palindrome in the three numbers and in the letters:

5 * 5 * 1 * 3 * 3 * 1 = 225

1st Number 2nd 3rd 1st Letter 2nd 3rd

Then, It can be created 1575 license plates with at least one three-piece palindrome and it is calculated as:

450 + 900 + 225 = 1575
