Answer:

$820

Step-by-step explanation:

D= Diamond Ring

S= Silver Ring

2D + 4S = 1880

D + S = 880

D = 880 - S

4S + 2(880 - S) = 1880

4S + 1760 - 2S = 1880

2S + 1760 = 1880

2S =  120

S = 60

880 - 60 = 820.

Feliz [49]

Answer:

84 months

Step-by-step explanation:

I × 100 = P × R × T

I = interest = $245

P = principal = $1750

R = rate = 2%

T = time(in years) = ??

245 × 100 = 1750 × 2 × T

24500 = 3500T

24500/3500 = T

7 = T

To convert the time to month:

7 × 12 = 84 months

there is 1 litre of tea in a teapot, alex pours 275ml of the tea into a cup what percentage of the tea has alex poured
Nuetrik [128]

Answer:

27.5%

Step-by-step explanation:

Given:

  • 1 Liter In Teapot
  • Alex poured 275 milliliters of the tea into a cup

Review:

  • 1,000 Milliliters = 1 Liter

Concepts:

  • A liter is a noun meaning a unit of capacity redefined in 1964 by a reduction of 28 parts in a million to be exactly equal to one <em>cubic </em>decimeter. It is equivalent to <em>1.0567</em>  U.S. liquid <u>quarts </u>and is equal to the volume of 1 kilogram of distilled <em>water</em> at 4°C.
  • A millimeter is a noun meaning a unit of capacity <em>equal</em> to one <u>thousandth </u>of a liter, and equivalent to <em>0.033815</em> fluid<u> </u><u>ounce</u>, or<em> 0.061025</em><em> </em>cubic<u> inch</u>.

Formula:

  • The <em>mℓ</em> to <em>ℓ</em> formula is<em> [L] = [mL] / 1000</em>.

Now we must convert <em>275</em> milliliters to liters.

1. Divide the volume by <em>1,000.</em>

275 ÷ 1000 = 0.275

2. Add the Unit Symbol for Liter.

0.275 ⇒ 0.275 L

Now we have to find how much of 1 liter- 0.275 liters as a percentage is.

To convert <em>0.275</em> to percent multiply <em>0.275</em> by <em>100</em>. The result is <em>27.5 </em>percent, or, using the percent sign, <em>27.5 %.</em>
