Answer:

Total cost of the speakers including sales tax = $ 261

Step-by-step explanation:

Price of set of speakers = 245

Sales tax 6.5% = 245*6.5% = 15.925

Total cost of the speakers including sales tax = 245+15.925 = 260.925

$261 when rounded off to nearest whole number.

Luke bought three canvas boxes to store his papers. The canvas boxes have dimensions of 12 inches by 10 inches by 12 inches. Wha
irga5000 [103]

Answer: 4,320 inches cubed.

Step-by-step explanation:

step 1----- Volume of 1 canvas box

Volume of solid  for a rectangular box = Length x width xHeight

where  Length= 12inches,

Width= 10 inches

Height= 12 inches

Volume  of a Canvas box= 12 X 10 X 12= 1440 inches cubed

Step 2== Volume of 3 canvas boxes

1 canvas box = 1440 inches cubed

therefore 3 canvas boxes =

1440 x 3= 4320 inches cubed.

What is the value of x?<br><br> Enter your answer in the box.<br><br> x =
Assoli18 [71]

Answer:

x = 5

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 12² = 13², so

x² + 144 = 169 ( subtract 144 from both sides )

x² = 25 ( take the square root of both sides )

x = \sqrt{25} = 5

Answer:

2 and - \frac{1}{2}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3y = 6x + 9 ( divide all terms by 3 )

y = 2x + 3 ← in slope- intercept form

with slope m = 2

(i)

Parallel lines have equal slopes, thus

the slope of line t is 2

(ii)

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{2}, thus

the slope of line r is - \frac{1}{2}

The numbers x and y are inversely proportional. When the sum of x and y is 42, x is twice y. What is the value of y when x = -8?
dolphi86 [110]

Answer:

y= -4

Step-by-step explanation:

x+y=42.   We know that x plus y equals 42.

x=2y .   We also know that x equals twice y.

2y+y=42.   Since we know that x=2y, we're going to replace x with 2y from the original equation, simplified would be 3y=42.

y=14.   3y=42 simplified is y=14, this is because we divided both sides by 3 (since 3 and 42 are both divisible by 3) (btw divisible by 3 simply means that it can be divided by 3)

x+14=42.   Now that we know what y equals, let's replace y with 14 from the original equation.

x=28.  Now that we know that x=28 and y=14, we know that y is always x/2.

When x=-8, we divide it by 2 and get, -4.

Not absolutely positive as this was all mental math, but hope this helps! :)
