Diane keeps all of her toys on a shelf. The shelf is 24" long and 7" wide. If the wdith the shelf is doubled, what would happen
goblinko [34]

Step-by-step explanation:

Given that,

The length of the shelf = 24 inches

The width of the shelf = 7 inches

Area of the shelf, A = 24 × 7

= 168 inch²

When the width of the shelf is doubles,

New width = 14 inch

New area, A' = 14×24

= 336 inch²

It means,

A' = 2(A)

So, the new area becomes 336 inch² i.e. twice the initial area.

Please help me it’s due tonight and I’m stuck on this question!!
solniwko [45]

Answer:

The length of the ramp is 7.3 meters.

Step-by-step explanation:

The length of a triangle's side must be less than the sum of its two other sides. It also cannot have the same value as its other combined sides.

7 + 2 > 7.3

2 + 7.3 > 7

7 + 7.3 > 2

<em>r</em> is also longer than 7 meters, so that leaves option b. as your answer.

solong [7]
 <span>Northwest is 45 degrees north of west. If a car travels a distance x miles northwest, its northerly component gains x/sqrt(2) miles and its easterly component LOSES xsqrt(2)/ miles. 

Resultant height is h = 4500 + 100x/sqrt(2) - 75x/sqrt(2) = [25/sqrt(2)]x + 4500 
dh/dt = [25/sqrt(2)]dx/dt = [25/sqrt(2)]v </span>
