Answer:

y = 10

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = $\frac{1}{2}$ , then

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{y}{20}$ = $\frac{1}{2}$ ( cross- multiply )

2y = 20 ( divide both sides by 2 )

igor_vitrenko [27]

Write an expression for the total cost of the tools.

total cost = $11.79 (4) + $6.65 (7)

Then find the total cost.

total cost = $11.79 (4) + $6.65 (7)
total cost = $47.16 + $46.55 = $93.71

Answer:

Price of Caleb's groceries before tax = $64

Step-by-step explanation:

Let the price of groceries before tax be =$ $x$

Sales tax charged = $1.60

Sales tax rate =2.5%

Sales tax charged in terms of $x$ will be = 2.5% of the Original price of grocery = $2.5\% of x = 0.025\times x=0.025x$

So, we have,

$0.025x=1.60$

Dividing both sides by $0.025$

$\frac{0.025x}{0.025}=\frac{1.60}{0.025}$

∴ $x=64$

∴ Price of Caleb's groceries before tax = $64
