Answer: 3.971

Step-by-step explanation: first, you need to set up your addition problem. When adding decimals, you need to line up the decimal points. So you get something like this:

3.85

0.004

0.117

+————-

Then you add vertically and you get your answer of 3.971

Your welcome :)

$\frac{3}{2}$ part of length of the third towel is the length of the second towel

Solution:

Given that You have towels of 3 sizes

Length of the first towel = $\frac{3}{4}$ meter

The length of one of them is equal to 3/4m, which makes up 3/5 of the length of the second.

Length of the first towel = $\frac{3}{5} \times \text{ length of second towel }$

$\frac{3}{4} = \frac{3}{5} \times \text{ length of second towel }\\\\\text{length of second towel }= \frac{5}{4}$

The length of the third towel makes up 5/12 of the lengths of the first 2.

$\text{ length of the third towel }= \frac{5}{12} \times (\text{ length of first towel + length of second towel)}$

$\text{ length of the third towel }= \frac{5}{12} \times (\frac{3}{4} + \frac{5}{4}) = \frac{5}{12} \times 2 = \frac{5}{6}$

To find: What part of the length of the third towel is the length of the second towel ?

Ratio of second to third towel length = $\frac{\frac{5}{4}}{\frac{5}{6}}=\frac{5}{4} \times \frac{6}{5}=\frac{3}{2}$

Thus 3/2 part of length of the third towel is the length of the second towel

If the discriminant of a quadratic equation is equal to -8, which statement describes the roots?

Dovator [93]

Keywords

quadratic equation, discriminant, complex roots, real roots

we know that

The formula to calculate the roots of the quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}}{2a}$

where

The discriminant of the quadratic equation is equal to

$b^{2}-4ac$

if $(b^{2}-4ac)> 0$ ----> the quadratic equation has two real roots

if $(b^{2}-4ac)=0$ ----> the quadratic equation has one real root

if $(b^{2}-4ac)< 0$ ----> the quadratic equation has two complex roots

in this problem we have that

the discriminant is equal to $-8$

the quadratic equation has two complex roots

therefore

the answer is the option A

There are two complex roots

What does 5/4x = 1/2

aleksklad [387]

You would multiply 4 on both sides
5x=2
then you would divide 5 on both sides
x=2/5

Stan worked 4 years less than Marco.This year Stan has worked 29 years.If b is how long Marco worked, the equation b - 4 = 29 re

MA_775_DIABLO [31]

Answer:

Add 4 on both sides.

In the equation there is a -4.

If -4+4=0, that is how you would get rid of the -4.

But, you need to add 4 to 29 to really get rid of the -4.

So, 29+4 is 33.

b=33
