What is 1/8 in a decimal

Answers

To get the answer, divide 1 by 8
Which equals 0.125
And that is your answer.

Hope I Helped You!!! :-)

Have A Good Day!!!

This is an easy rule to use. Whenever you have a fraction divide the numerator into the denominator to find the percentage. It's easiest to do with a calculator.
For example, 1/2 is 50%. We know that, but how did we get 50%?
1 divided by 2 is .5 All you have to do is add a zero.
1÷2=.5 ----> 50%
Now with your problem, all you have to do is apply the same rule.
1÷8= .125 Be careful though. This does NOT mean 125% This means 12.5% or if you want to round it, it's 13%. The only reason why is because wherever the number in the hundreds place is, that's where you add the decimal. This is because percentages are measured by 100.
So the answer is 12.5% because 1 ÷ 8= .125

The angles of a quadrilateral measures 80,100. 100 and 80 in this order . what kind of quadrilateral has this shape? how do you know?

Answers

The quadrilateral is an isosceles trapezoid because it has two adjacent, equal acute angles and two adjacent, equal obtuse angles.

Please help I only have today to do this type of work and I'm struggling!! Alice, Raul, and Maria are baking cookies together. They need cup of flour and cup of butter to make a dozen cookies. They each brought the ingredients they had at home. Alice brought cups of flour and cup of butter, Raul brought cup of flour and cup of butter, and Maria brought cups of flour and cup of butter. If the students have plenty of the other ingredients they need (sugar, salt, baking soda, etc.), how many whole batches of a dozen cookies can they make?

2 sin^2 (x) -5 sin (x) -3=0 I. Rewrite the equation by substituting the expression u in for sin x.

II. Factor the quadratic expression. Rewrite the equation with factors instead of the original polynomial.

III. Use the zero product property to solve the quadratic equation.

IV. Rewrite your solutions to Part III by replacing u with sin x.

V. Solve the remaining equations for x, giving all solutions to the equation.

Answers

we have that

$2sin^(2) x-5sin x-3=0$

I. Rewrite the equation by substituting the expression u in for sin x.

$2u^(2) -5u-3=0$

II. Factor the quadratic expression. Rewrite the equation with factors instead of the original polynomial.

$2u^(2) -5u-3=0$ is equal to

using a graph calculator-----> see the attached figure

$(u-3)*(2u+1)=0$

III. Use the zero product property to solve the quadratic equation.

$(u-3)*(2u+1)=0$

(u-3)=0--------------> u=3

(2u+1)=0-------- 2u=-1------> u=-1/2-----> u=-0.5

IV. Rewrite your solutions to Part III by replacing u with sin x.

sin x=3--------> is not the solution (sin x can not be greater than 1)

sin x=-0.50------>is the solution

V. Solve the remaining equations for x, giving all solutions to the equation.

sin x=-0.50

if the sine is negative

then

x belong to the III or IV quadrant

we know that

sin 30°=0.50

the solution for the III quadrant is

x=180°+30°-------> x=210°

the solution for the IV quadrant is

x=360°-30°------> x=330°
