Step-by-step explanation:

use the acroname sohcahtoa

<em><u>sin </u></em><em><u>6</u></em><em><u>0</u></em><em><u>=</u></em><em><u>8</u></em><em><u>√</u></em><em><u>3</u></em><em><u>/</u></em><em><u>h</u></em>

sin60=0.8660 while 8√3=13.8564

divide both side by 0.8660

0.8660/0.8660=13.8564/0.8660

A jar of quarters and dimes has total value of $20.70. The jar has 10 more quarters than dimes. To find the numbers of quarters
lakkis [162]

There are 62 quarters and 52 dimes in the jar.

Step-by-step explanation:

Given,

Worth of jar coins = $20.70 = 20.70*100 = 2070 cents

1 Quarter = 25 cents

1 Dime = 10 cents

Let,

Number of quarters = x

Number of dimes = y

According to given statement;

25x+10y=2070    Eqn 1

x=y+10     Eqn 2

Putting value of x from Eqn 2 in Eqn 1

25(y+10)+10y=2070\\25y+250+10y=2070\\35y=2070-250\\35y=1820\\

Dividing both sides by 35

\frac{35y}{35}=\frac{1820}{35}\\y=52

Putting y=52 in Eqn 2

x=52+10\\x=62

There are 62 quarters and 52 dimes in the jar.

The value of a certain car decreases by 16% each year. What is the 1⁄2-life of the car?
svet-max [94.6K]

Answer:

The half life of the car is 3.98 years.

Step-by-step explanation:

The value of the car after t years is given by the following equation:

V(t) = V(0)(1-r)^{t}

In which V(0) is the initial value and r is the constant decay rate, as a decimal.

The value of a certain car decreases by 16% each year.

This means that r = 0.16

So

V(t) = V(0)(1-r)^{t}

V(t) = V(0)(1-0.16)^{t}

V(t) = V(0)(0.84)^{t}

What is the 1⁄2-life of the car?

This is t for which V(t) = 0.5V(0). So

V(t) = V(0)(0.84)^{t}

0.5V(0) = V(0)(0.84)^{t}

(0.84)^{t} = 0.5

\log{(0.84)^{t}} = \log{0.5}

t\log{0.84} = \log{0.5}

t = \frac{\log{0.5}}{\log{0.84}}

t = 3.98

The half life of the car is 3.98 years.
