Answer:

61.7

Step-by-step explanation:

Let the number be x

% increase in the number : 7

Thus , actual increase in number will be 7% of x = 7/100 of x = 7x/100

Thus, new number with 7% increase = x+ 7x/100

given that value of new number with 7% increase is 66

Thus,

x+ 7x/100 = 66

=> (100x+7x)/100 = 66

=> 107 x = 66*100

=> x = 6600/107 = 61.682

Thus, original number is 61.682

but we have to find the number to nearest tenth .

original number is 61.7

The measure of 5 of the interior angles of a hexagon are 110, 120, 90, 140, and 125. what is the measure of the smallest exterio
Romashka-Z-Leto [24]

Answer:

A) 40

Step-by-step explanation:

The sum of the interior angles of a regular polygon is:

(n - 2) \times 180

For a hexagon, we put n=6

(6 - 2) \times 180 = 4 \times 180 = 720

Let x be the 6th interior angle, then

x + 110  + 120 + 90 + 140 + 125 = 720

x + 585 = 720

x = 720 - 585 = 135

The largest interior angle is 140°

Therefore the least exterior angle will be:

180 - 140 = 40

The correct choice is A

The equation is y=mx+b.
ycow [4]

Answer: both ways are acceptable

Step-by-step explanation: When writing equations of lines in this form,

we usually keep the "b" value or the constant term as a fraction.

However, if you prefer decimals, you can absolutely change

it to a decimal to visualize is better if you'd like, it's really your choice.

For example, if the equation of a line was y = -3/4x - 7/4, I could leave

it how it is or I could change the -7/4 to -1.75 giving me y = -3/4x - 1.75.
