Answer:

x - 18°F = 2°F

x = 20°F

Step-by-step explanation:

First, write the equation with the information you know. It dropped 18°F from 6 to midnight, and by midnight the temperature was 2°F

Your equation should look like this: x - 18°F = 2°F

Move the constant to the right hand side and change it's sign:

x = 2°F + 18°F

Add the numbers to get x = 20°F

Hope this helped!

victus00 [196]

Answer:

1) 16\frac{2}{3}% or 20%

Step-by-step explanation:

Given that:

An experiment which is carried out by flipping a coin and rolling six sided die.

The outcomes can be:

{H1, H2, H3, H5, H6, T1, T1, T2, T3, T5}

As per question statement:

Number of outcomes having tails and an odd number greater than one is 2 (i.e. T3 and T5)

Total number of outcomes here is 10.

Therefore, to find the percentage, we use the following formula:

\dfrac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\times 100

\Rightarrow \dfrac{2}{10}\times 100 = 20\%

As per question statement, the answer is 20%.

If we consider all the outcomes, i.e.

{H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6}

Total number of outcomes = 12

The percentage will come out be :

\Rightarrow \dfrac{2}{12}\times 100 = 16\frac{2}{3}\%

Plz answer this correctly and not some stupid answer, See picture. 10th grade level.
vichka [17]

9514 1404 393

Answer:

  -101 feet

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that the relevant relation is ...

  Tan = Opposite/Adjacent

  Opposite = Adjacent × Tan

  height = (0.5 × 5280 ft) × tan(47°) ≈ 2831 ft

__

The usual relation between estimates and errors is ...

  error = estimate - actual

Then ...

  actual = estimate - error

For the given angle and error, the actual angle is ...

  actual angle = 47° -(-1°) = 48°

  actual height = (2640 ft)·tan(48°) ≈ 2932 ft

Then the change in the height of the mountain due to the error is ...

  2831 ft -2932 ft = -101 ft

The error of -1° in angle estimate creates an error of -101 ft in the height estimate.
