Answer:

7) 230mm

8) 98m

Step-by-step explanation:

7)

7x+8+6x+6+9x-4 =22x+10

if x is 10 mm, 22(10)+10 =230mm

8) perimeter of rec =2( l + w )

=2 ( 2x-5+2x+6 ) = 8x + 2

if x  is 12 metres, 8(12)+2 =98m

Hillary needs a few new items for the start of softball season. She found some great sales! Help her find out the price she will
kolezko [41]

Answer:Hillary will pay $35.00 for softball glove, $20.00 for  soft ball bat and $40.00 for cleats

Step-by-step explanation:

Step 1

A percentage off of a price of an item  is the amount that can be saved from purchasing that item, it can also be referred as a discount given on an item purchase.

Step 2 --- Calculation

Actual  Price of Softball glove= $50

Discount= 50 x 30/100 = $15.00

 Price to pay= $50 - $15.00 = $35.00

Actual Price of soft ball bat= $50

Discount= 50 x 60/100 = $30.00

 Price to pay= $50 - $30.00 = $20.00

Actual Price of cleats= $50

Discount= 50 x 20/100 = $10.00

Price to pay= $50 - $10.00 = $40.00

Therefore, Hillary will pay $35.00 for softball glove, $20.00 for  soft ball bat and $40.00 for cleats

At 2063 ft, the KVLY-TV tower in North Dakota is the world’s tallest supported tower. How long would it take an object to fall f
IgorLugansk [536]
Use the equation of motion under gravity:-

s =  16t^2    where s is the distance and t = time

2063 = 16t^2

t^2 = 2063 / 16 =  128.94 s

t = sqrt 128.94  =  11. 4 seconds to the nearest tenth of a second

A painter starts with a blank 24-inch by 12-inch piece of rice paper. The painter wants to leave a uniform border x inches wide
ddd [48]

Answer:

a. A = x² - 36x + 288

b. If x = 2; A = 220 in²

Step-by-step explanation:

<h2>a.</h2>

In this scenario, 'x' represents the width of the border. A "uniform border" means that the border has the same width all around.

The area of the paper that can be painted does not include the border. Since the border is on the original rice paper (not added to it), you subtract 'x' from each side of the rice paper.

The area of a rectangle is A = lw (Area is length times width). <u>Each length and width is reduced by 'x'.</u>

If the original rice paper's area is: 24 X 12, then,

the Area that can be painted is:

A = (24 - x) (12 - x)

A polynomial in standard form means the most expanded version of an expression, ordering the terms (numbers) from greatest to least degree. (The degree of a term is the value of its exponent).

Expand the expression. Multiply the numbers from each bracket in the order FOIL (first, outside, inside last):

A = (24 - x) (12 - x)

= 288 - 24x - 12x + x²        Collect like terms (-24x - 12x = -36x)

= 288 - 36x + x²        Rearrange ordering greatest to least exponent value

= x² - 36x + 288        Standard form polynomial

<h2>b.</h2>

The width of the margin is the same thing as the width of the border. Since 'x' is the width of the border,

x = 2

Using either the expanded or factored equation for area of that can be painted, substitute 'x' for 2.

I will use the factored form.

A = (24 - x) (12 - x)        Substitute x for 2

= (24 - 2) (12 - 2)          Solve inside each bracket first by subtracting

= (22) (10)             Multiply

= 220                 Area that can be painted

Remember to include the units: 220 in²

Therefore if the margin is 2 inches wide, then the area that can be painted in 220 square inches.
