In 2014, adele sold 2,500,000 records. In 2015, she sold 90% of the number of records she sold in 2014. In 2016, she sold 80% of the number of records she sold in 2015. How many records did she sell in 2016?

Answers

Answer 1
She sold 70% bc 100% - 90% - 80% -70%
Answer 2
90% of 2.5 million is 2.25 million (2.5 x .9 = 2.25)

80% of 2.25 million is 1.8 million (2.25 x .8 = 1.8)

Adele sold 1,800,000 records in 2016

What is 56 x 2 1/8? If you answer, you get 20 points.

Answers

Answer:

119

Step-by-step explanation:

so umm for me i have to convert it to a (i forgot the name for the opposite of mixed number lets just say a) a

soooo

2 1/8

17/8

now multiply

56 (17/8)

952/8

119

Answer:

119

Step-by-step explanation:

Convert into mixed numbers 2 1/8= 17/8

How to get that is

2 1/8= 2 times 8 + 1 divided by 8 = 17/8

Now you have 56 times 17/8

Convert element to fraction

56/1 times 17/8

Apply fraction rule

56 times 17 over 1 times 8

Multiple the denominators (1 times 8=8)

Now you have 56 times 17 over 8

Divide the numbers 56/8=7

Now, multiply

7 times 17= 119

Edward deposited $2250 into a savings account 3 years ago. The simple interest rate is 4%.


Edward earned $ __ in interest.


His new account balance is ___$ . (pls step by step explanation)

Answers

He earned $270 and has $2520 because 2250(0.04)(3)= 270

Edward earned $ 270 in interest

How/Solution:

Multiply $2,250 by 4% (0.04)
[ $2,250 x 0.04 = 90]
and it equal to 90, then multiply it again by 3 [ 90 x 3 = 270 ]

His new account balance is $ 2,520

Solution:

Add $2250 by $270
[ $2,250 + $270 = $ 2,520 ]

22k - 39 = 11k + 2(10k+12)


PLEASE show your steps!

Answers

Answer: K = -7

Explanation:

22k - 39 = 11k + 20k + 24

22k - 39 = 31k + 24

22k - 31k = 24 + 39

-9k = 63

K = -7

Answer:

[tex]k=-7[/tex]

Step-by-step explanation:

[tex]22k-39=11k+2\left(10k+12\right)[/tex]

Apply the Distributive Property

[tex]22k-39=11k+20k+24[/tex]

Combine like terms

[tex]22k-39=31k+24[/tex]

Rearrange variables to the left side of the equation

[tex]22k-31k=24+39[/tex]

Combine like terms

[tex]-9k=24+39[/tex]

Calculate the sum or difference

[tex]-9k=63[/tex]

Divide both sides of the equation by the coefficient of variable

[tex]k=-\frac{63}{9}[/tex]

Cross out the common factor

[tex]k=-7[/tex]

camelbeck mountain has an elevation change of 1,264 feet. how many pennies would it take to make a stack that high? show all work.

Answers

Camel back Mountain = 15,168 inches (1,264 feet)
1 Penny = 0.061 (.0610) Inches
10 Penny = 0.61 (.610) Inches
100 Penny = 6.1 (6.10) Inches
1,000 Penny = 61 (61.0) Inches
10,000 Penny = 610 (610.0) Inches
-SOLVING-
10,000 Penny = 610 inches PLUS
1,000 Penny = 61 inches AND 61 inches x 5 = 305 (5,000 Penny)
100 Penny = 6.1 inches PLUS
10 Penny = 0.61 inches AND 0.61 inches x 6 = 3.66 (60 Penny)
1 Penny = 0.061 inches AND 0.061 inches x 8 = 0.488 (8 Penny)
-FINAL ANSWER-
610 + 305 + 6.1 + 3.66 + 0.488 = 925.248 Penny it would take.
