1,2,3,4 are the domain. The x column is always the domain.

we can use formula

$\theta=tan^{-1}(\frac{a_y}{a_x})$

(a)

we are given

$a_x=12,a_y=12$

now, we can plug values

$\theta=tan^{-1}(\frac{12}{12})$

$\theta=tan^{-1}(1)$

$\theta=\frac{\pi}{4}rad$

(b)

we are given

$a_x=20,a_y=12$

now, we can plug values

$\theta=tan^{-1}(\frac{12}{20})$

$\theta=tan^{-1}(\frac{3}{5})$

$\theta=30.96^{\circ \:}$

(c)

we are given

$a_x=12,a_y=20$

now, we can plug values

$\theta=tan^{-1}(\frac{20}{12})$

$\theta=tan^{-1}(\frac{5}{3})$

$\theta=59.03^{\circ \:}$

Jason worked 20 hours at $5 per hour and 30 hours at $6 per hour. What was his average hourly wage Please show all your work

11111nata11111 [884]

Jason worked 20 hours at $5 per hour and 30 hours at $6 per hour.

20 hours at $5 per hour = 20 times 5

$20 \times 5 = \$100$

30 hours at $6 per hour = 30 times 6

$30 \times 6 = 180$

$180 + 100 = 280$

He earned $280 in 50 hours. Divide:

$280 \div 50 = 5.6 \rightarrow 5.60$

Your answer is the last choice, $5.60

first you would put the expression in a fraction for

180/460

you already know that the both numbers are divisible by 2

so the answer would be 90/230 but we are still no done because these values are divisible by three

the rule to prove that the number is divisible by three is when you add the digits of the number for example 333. 3+3+3=9 and nine is divisible by nine

THE ANSWER IS:::::::: 90/230

Janice has three times as many dimes as nickels. If the total value of the money is $9.10, how many of each types of coin does s

ICE Princess25 [194]

X= number of nickels
3x= number of dimes

Each nickel is $0.05 and each dime is $0.10. Multiply each coins monetary value by the quantity of each. Add them equal to the total $9.10.

(0.05 * x) + (0.10 * 3x)= 9.10
multiply inside parentheses

0.05x + 0.3x= 9.10
add

0.35x= 9.10
divide both sides by 0.35x

x= 26 nickels

DIMES
3x= 3(26)= 78 dimes

CHECK:
(26 nickels * 0.05) + (78 dimes * 0.10)= 9.10
$1.30 + $7.80= $9.10
$9.10= $9.10

ANSWER: There are 26 nickels and 78 dimes.

Hope this helps! :)
