What is 39.79949748 rounded to the nearest hundredth?

Rufina [12.5K]

Answer:

$Number = 39.80$

Step-by-step explanation:

Given

$Number = 39.79949748$

Required

Approximate (to the nearest 100th)

This means that, we approximate at the second digit after the decimal.

So:

i.e,

Number = 39.79 [Begin approximation] 949748

The first digit after [Begin approximation] is then approximated using the following rule:

$0 - 4 \approx 0$

$5 - 9 \approx 1\\$

Since 9 falls in $5 - 9 \approx 1\\$ category, the number becomes:

$Number = 39.[79+1]$

$Number = 39.80$

∠1 and ∠2 are complementary. If m∠1 = 4m∠2, find m∠1

77julia77 [94]

Answer:

∠1 = 72°

Step-by-step explanation:

Complementary angles sum to 90°, thus

∠1 + ∠2 = 90, substitute ∠1 = 4∠2 , thus

4∠2 + ∠2 = 90

5∠2 = 90 ( divide both sides by 5 )

∠2 = 18°

Hence ∠1 = 90 - 18 = 72°

Camden has an action figure collection of 380 action figures. He keeps 55% of the action figures on his wall. How many action fi

svet-max [94.6K]

209 action figures on his wall

380/100 = 3.8
so there would be 3.8 action figures per 1%
then 3.8*55 =209

Write the standard equation of a circle with center (2, −5) and radius 16.

astra-53 [7]

The standard equation of circle when center is (h,k) and radius is 'r'

$\left ( x - h \right )^{2} + \left ( y - k \right )^{2} = r^{2}$

h = 2 and k = - 5, radius = 16

So equation of the circle is given by

$\left ( x - 2 \right )^{2} + \left ( y - (-5) \right )^{2} = 16^{2}$

$\left ( x - 2 \right )^{2} + \left ( y + 5) \right )^{2} = 256$
