What is 5.264 rounded to the nearest hundredth

yKpoI14uk [10]

<em>If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).</em>

<em>If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).</em>

5.26<u>4</u> ≈ 5.260 = 5.26

Answer:

1000 x .15 = 150 The car will lose 15% value after the first year which is $150. Subtract 150 from 1000 and the new value would be $850.

5020 x .15 = 753 This car lost 15% after the first year which is $753. Subtract 753 from 5020 and the new value would be $4287.

Answer:

$\Huge\boxed{29.3}$

Step-by-step explanation:

Hello There!

<u>Remember The Trigonometric Ratios</u>

Sin = opposite divided by hypotenuse

Cos = adjacent divided by hypotenuse

Tan = opposite divided by adjacent

We need to find the measure of angle X given the opposite side length and hypotenuse

Opposite and hypotenuse correspond with sine so we are going to use sine to solve for x

We create an equation: $sin(x)=\frac{43}{88} \\$

$\frac{43}{88} =.4886363636\\sin(x)=.4886363636$

Now we want to get rid of the sin

To do so we take the inverse of sin (which would be arcsin) and apply it to each side

$arcsin^-^1(sinX)=x\\arcsin^-^1(.4886363636)=29.25099306$

finally we round to the nearest tenth

we're left with x = 29.3
