As you already written, you have to use Newton's law

F=ma

where F is the force, m is the mass, and a is the acceleration.

You already know the mass and the force, so you have to solve the equality for the acceleration:

a = \dfrac{F}{m}

plug the given values:

a = \dfrac{150}{160} = \dfrac{15}{16} = 0.9375

For the arithmetic sequence 42, 32, 22, 12... find the 18th term.
Stella [2.4K]

Answer:

The18th term of the given sequence is -128

Explanation:

To find the 18th term of the sequence:

42, 32, 22, 12, ..., we need to find the nth term of the sequence first.

The nth term of a sequence is given be the formula:

T_n=a+(n-1)d

Where a is the first term, and d is the common difference.

Here, a = 42, d = 32 - 42 = -10

\begin{gathered} T_n=42+(n-1)(-10) \\ =42-10n+10 \\ T_n=52-10n \end{gathered}

To find the 18th terem, substitute n = 18 into the nth term

\begin{gathered} T_{18}=52-10(18) \\ =52-180 \\ =-128 \end{gathered}

6/7 =  828/x

Write a proportion.

6x = 7(828) Use cross products.

6x = 5796 Multiply.

x = 966 Divide both sides by 6.

Paul's investment was $966.

a car decreased in value from $980 to $720 in one year what was the per cent of decrease to the nearest whole per cent ?
kolezko [41]

The decrease was 27%.

Step-by-step explanation:

Old value = $980

New value = $720

Decrease = Old value - New value

Decrease=980-720=\$260

Percent decrease = \frac{Decreased/ amount}{Old value}*100

Percent\ decrease=\frac{260}{980}*100\\Percent\ decrease=0.265*100\\Percent\ decrease= 26.5\%

Rounding off to near whole percent

Percent decrease = 27%

The decrease was 27%.
