When a number is decreased by 3.5%, the result is 91 what is the original number to the nearest tenth

The number is 94.3 (to the nearest tenth)

Step-by-step explanation:

Let the number =x

When x is decreased by 3.5%, we have:

(100% of x)-(3.5% of x)=(100-3.5)% of x =96.5% of x

When a number is decreased by 3.5%, the result is 91.

Therefore:

96.5% of x = 91

Converting percentage to decimal: 96.5%=0.965

0.965x = 91

Divide both sides by 0.965

x=94.3

The number is 94.3 (to the nearest tenth)

left 3, up 4

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
