It is multiplied by 100

The rule associated with moving decimal places, and multiplying by a value or multiple of 10, would be the following :

If you divide a value by 10 or a multiple of 10, you would move the decimal place to the left number of times as there are zeros in the multiple.

(Assuming that there are no zeros in the numerator value)

If you multiply by 10 multiple, then you would move the decimal to the right that many times as there are 0's in the value.

The solution would be that the decimal number is multiplied by 100.

What is the difference between the temperatures at 10 a.m. and 3:30 p.m.? Indicate whether the change is an increase or decrease
dsp73

Answer:

Change in temperature = - 3.3 F

The temperature has decreased

Step-by-step explanation:

The complete question is attached below .

As given in the attached image

Temperature at 10 A.M = 1.2 degree Fahrenheit

Temperature at 3:30 P.M. = -2.1 degree Fahrenheit

Change in temperature

= Temperature at 3:30 p.m - Temperature at 10 a.m

= - 2.1 - 1.2

= - 3.3 F

The temperature has decreased

drawbridge at the entrance to an ancient castle is raised and lowered by a pair of chains. The figure represents the drawbridge
jasenka [17]

Answer:

4.0 meters, ∠C = 39°, ∠A = 51°

Step-by-step explanation:

Firstly, our diagram shows us that the given triangle is actually a right triangle. So we can use the <em>Pythagorean Theorem</em> to solve for the height of the chain:

a^{2} +b^{2} =c^{2}

(3.3)^{2} +b^{2} =(5.2)^{2}

b^{2} =(5.2)^{2}-(3.3)^{2}

b =\sqrt{(5.2)^{2}-(3.3)^{2}}

b=4.0187...

b=4.0 m

Now, we can use the <em>Law of Cosines</em> to figure out one of the acute angles:

c^{2}  =a^{2} +b^{2} -2ab(cos(C))

(3.3)^{2}  =(4.0)^{2} +(5.2)^{2} -2(4.0)(5.2)(cos(C))

cos(C)=\frac{(3.3)^{2}-(4.0)^{2} -(5.2)^{2}}{-2(4.0)(5.2)}

C=cos^{-1}( \frac{(3.3)^{2}-(4.0)^{2} -(5.2)^{2}}{-2(4.0)(5.2)})

C=39.3915...

∠C = 39°

And since we know that all angles in a triangle add up to 180°:

∠A + ∠B + ∠C = 180

∠A + 90 + 39 = 180

∠A = 180 - 90 - 39

∠A = 51°

However, you should always review any answers on the Internet and make sure they are correct! Check my work to see if I made any mistakes!
