Mathematics
1 answer:
lozanna [386]3 years ago
5 0

Answer:

  1. d = 2/3
  2. c = 3/2
  3. y = 2/3
  4. x = 4 2/19

Step-by-step explanation:

<u>Solving for variables</u>

1.......................................

  • 4 2/9 =6 1/3∙d
  • 38/9= 19/3d
  • d = 38/9 ÷ 19/3
  • d = 38/9*3/19
  • d = 2/3

2.......................................

  • c÷ 2/11 =8 1/4
  • c ÷ 2/11 = 33/4
  • c = 33/4*2/11
  • c = 3/2

3.......................................

  • 2 1/2 =1 2/3÷y
  • 5/2 = 5/3 ÷ y
  • y = 5/3 ÷ 5/2
  • y = 5/3 * 2/5
  • y = 2/3

4.......................................

  • 6x=24 12/19
  • 6x = 24 + 12/19
  • x = 24/6 + 12/19 *1/6
  • x = 4 + 2/19
  • x = 4 2/19

real estate julie bought a house for $100,00 five years ago. if the value of the house has appreciated 5% per year , how much is
Stels [109]
To find the answer, turn the appreciated percent into a decimal:

5% ----> .05 (Divide by 100)

Then multiply it by the total value:

100,000 x .05 = 5000

Then add that to the total:

105,000

So the house is worth a total of $105,000.

Hope this helps!

Given log Subscript 3 Baseline 2 almost-equals 0. 631 and log Subscript 3 Baseline 7 almost-equals 1. 771, what is log Subscript
kari74 [83]

You can use the properties of logarithm to get to the solution.

The approximate value for given term is given by

log_3(14) \approx 2.402

<h3>What is logarithm and some of its useful properties?</h3>

When you raise a number with an exponent, there comes a result.

Lets say you get

a^b = c

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

b = log_a(c)

Some properties of logarithm are:

log_a(b) = log_a(c) \implies b = c\\\\\log_a(b) + log_a(c) = log_a(b \times c)\\\\log_a(b) - log_a(c) = log_a(\frac{b}{c})

<h3>Using the above properties</h3>

log_3(2) + log_3(7) = log_3(2 \times 7) = log_3(14)\\\\0.631 + 1.771  = log_3(14)\\\\log_3(14) = 2.402

Thus,

The approximate value for given term is given by

log_3(14) \approx 2.402
