I need help on this

Naily [24]

Answer:x=90° y=58° z=32°

Step-by-step explanation:

x=90

y=180-(90+32) sum of angles in a triangle is 180

y=58

y+90+z=180 they are supplementary

58+90+z=180

148+z=180

z=180-148

z=32

You purchase a laptop for $399.99, a carrying case for $24.99 and some cleaner for $5.00. The sales tax rate on your purchase is

Lynna [10]

Answer:

$461.15

Step-by-step explanation:

Total amount of items:

Add all the prices together

399.99+24.99+5=429.98

Sales tax:

Convert 7.25% to a decimal

7.25/100=0.0725

Multiply the total by the decimal

429.98*0.0725=31.17355

Final cost:

Add the sales tax and total amount

429.98+31.17355=461.15355

Round to the nearest cent/hundreth

$461.15

Hope this helps! :)

Answer:

The correct way to set up the slope formula for the line that passes through points (5 , 0) and (6 , -6) is $\frac{-6-0}{6-5}$ ⇒ C

Step-by-step explanation:

The formula of the slope of a line passes through points $(x_{1},y_{1})$ and $(x_{2},y_{2})$

is $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

∵ The line passes through points (5 , 0) and (6 , -6)

∴ $x_{1}$ = 5 and $x_{2}$ = 6

∴ $y_{1}$ = 0 and $y_{2}$ = -6

Substitute these values in the formula of the slope

∵ $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

∴ $m=\frac{-6-0}{6-5}$

Let us look to the answer and find the same formula

The answer is:

The correct way to set up the slope formula for the line that passes through points (5 , 0) and (6 , -6) is $\frac{-6-0}{6-5}$

Solve the following equation

Nata [24]

Answer:

$\pm \frac{10}{3}$

Step-by-step explanation:

Given:

$\frac{4}{9} - \frac{x^2}{25}$

This can be written as $\frac{4}{9} = \frac{x^2}{25} = x^2 = 25 \times \frac{4}{9}$

$\implies x = \pm \sqrt{25 \times \frac{4}{9} }$

$\implies x = \pm 5 \times \frac{2}{3} = \pm \frac{10}{3}$
