Convert 4.5 to a mixed number help for brainlist with explanation!

Answers

Answer:

4 1/2

Step-by-step explanation:

the 4 means that the whole number will be 4. .5 means that there is one half of 1, so 1/2 will be the decimal

we can also write the decimal as an improper fraction.

45/10

then, reduce the fraction by 5

9/2

2 can go into 9 four times, so that is our whole number. 2 times 4 is 8, so there is 1 left in the numerator.

4 1/2

It’ll be 45/10!!!
With 4 being the whole number you multiple by the denominator which .5 being written as a fraction would be 5/10. With 4 multiples by 10 being 40, you then add the numerator 5 to get 45 and you write it as a fraction over 10.

Answers

Answer:

<A=67⁰

<B=22⁰

<C=42⁰

Mark me BRAINLIEST

Answer:

a = 67° , b = 26° , c = 69°

Step-by-step explanation:

a and 67° are corresponding angles and are congruent , so

a = 67°

------------------------------------------------------

The triangle on the left has 3 equal sides thus is equilateral with 3 congruent angles of 60°

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles , that is

b + 34° = 60° ( subtract 34° from both sides )

b = 26°

---------------------------------------------------

The vertex of the triangle and 42° are vertically opposite and are congruent

vertex = 42°

The triangle has 2 equal legs and is isosceles with 2 base angles congruent.

c = [tex]\frac{180-42}{2}[/tex] = [tex]\frac{138}{2}[/tex] = 69°

Under his cell phone plan, Josiah pays a flat cost of $37 per month and $3 per gigabyte. He wants to keep his bill at $43.60 per month. Write and solve an equation which can be used to determine xx, the number of gigabytes of data Josiah can use while staying within his budget.

Answers

The number of gigabytes of data Josiah can use while staying within his budget is 2.2 gigabytes.

Flat costs and Variable cost

The total amount of money that can be spent on the cell phone plan is the sum of the flat cost and the variable cost.

Total cost = flat cost + variable cost

Determination of the equation required to solve for the gigabytes needed

The flat cost is the cost that remains constant each month. The variable cost is the cost that increases by gigabyte used.

$43.60 = $37 + $3x

The gigabytes needed

In order to determine the value of x, combine similar terms together

$43.60 - $37 = $3x

6.6 = $3x

Divide both sides by 3

6.6/3 = x

x = 2.2 gigabytes

One of my grandmother's most vivid memories of Camp 3 was a riot between the Nisei and the Kibei. The Nisei and Kibei were Japanese Americans born in the United States, but they weren't all educated in America. The Nisei went to school in the United States, whereas the Kibei were mainly educated in Japan. Then they returned to the United States. In general, the Kibei opposed those Nisei who joined the U.S. Army to fight.
