Answer:

○ [tex]\displaystyle [\frac{1}{2}, ∞[[/tex]

Step-by-step explanation:

All you want to do is set the radical equal to zero to determine your domain, and sinse substituting [tex]\displaystyle \frac{1}{2}[/tex] in for [tex]\displaystyle x[/tex] would make this 0, it would be the INCLUDED endpoint, so your bracket faces [tex]\displaystyle \frac{1}{2},[/tex] then continues on infinitely.

I am joyous to assist you at any time.

**The ONLY time this is not the case is when you have a rationale-radical function, in which you must never have 0 in the denominatour.

Answer:

135 small cubes fill the prism

Step-by-step explanation:

Find the volume of the prism.

V = l * w * h

l = 2 1/4 = 2.25

w = 3/4 = 0.75

h = 1 1/4 = 1.25

V = 2.25 * 0.75 * 1.25

V = 2.109375

I wouldn't round this quite yet.

V of 1 small cube = 1/4 * 1/4 * 1/4 = .015625

So divide the volume of the prism by the volume of the small cube

2.109375/0.015625 = 135

Answer:

Age of Jose =  5 years

Age of Adrian = 13 years

Step-by-step explanation:

Let:

Age of Jose = x

Age of Adrian = x+8

After 3 years

Age of Jose = x+3

Age of Adrian = x+8+3 = x+11

Now, we are given, in 3 years he will be twice as old as his brother.

So, we can write

Age of Adrian = 2 (Age of Jose)

x+11 = 2(x+3)

x+11=2x+6

2x-x=11-6

x=5

So, we get value of x = 5

Now, the present ages will be:

Age of Jose = x = 5 years

Age of Adrian = x+8 = 5+8 = 13 years

Adrian is 8 years older than his brother, Jose. In 3 years, he will be twice as old as his brother. Find the present age of each.

Let's represent the age of Jose as [tex]\large\rm x[/tex]

According to the problem, Adrian is 8 years older than Jose, so Adrian's age can be represented as [tex]\large\rm x + 8[/tex].

In 3 years, Adrian's age will be [tex]\large\rm (x + 8) + 3[/tex] and Jose's age will be [tex]\large\rm (x + 3)[/tex].

The problem also tells us that in 3 years, Adrian will be twice as old as Jose:

[tex]\Large\begin{aligned}\rm{(x + 8) + 3}& =\rm{2(x + 3)}\\\rm{x + 11}&=\rm{2x +6}\\\rm{\cancel{x\red{-x}} + 11}&=\rm{2x \red{-x} + 6}\\\rm{11}&=\rm{x + 6}\\\rm{11\red{-6}}&=\rm{x + \cancel{6\red{-6}}}\\\bold{5}&=\rm{x}\end{aligned}[/tex]

So Jose is currently 5 years old.

To find Adrian's age, we can use the fact that Adrian is 8 years older than Jose:

[tex]\Large\begin{aligned}\rm{Adrian's\: age}& =\rm{x + 8}\\\rm{Adrian's\: age}&=\rm{\red{5} + 8}\\\rm{Adrian's\: age}&=\bold{13}\end{aligned}[/tex]

Therefore:

40    100

First, we need to multiply 90 by 40. 90x40=3,600.

Next, we have to divide 3,600 by 100. 3,600/100=36.

Answer:

SAS

Step-by-step explanation:

The ratio of 450 grams to 15 grams is 30:1.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

ratio of 450 grams to 15 grams

So, the ratio is

= 450/ 15

= 30 / 1

Hence, the ratio of 450 grams to 15 grams is 30:1.
