A full glass of water can hold 1/8 of a bottle.

How many glasses of water can be filled with 5 1/2 bottles of water?

Answers

5 1/2 bottles of water can fill 44 cups.

Step by Step Explanation:

First, lets start by making 5 1/2 an improper fraction. It would look something like this [tex]\frac{11}{2}[/tex]

From here, lets multiply it by [tex]\frac{4}{4}[/tex] so it's a number over an eighth so it's easier to understand. From this, we get: [tex]\frac {44}{8}[/tex]

Since we know that 1/8 of a bottle fills a cup, we can divide 44/8 by 1/8 to get us 44 full cups.

Chelsea is 55 3/ 4 inches tall. Carl is 1 3 /8 inches taller than Chelsea and Jane is 1 1 5 inches taller than Carl. How tall is Jane?

Answers

Answer:

Height of Jane = [tex]58\frac{13}{40} inches[/tex]

Step-by-step explanation:

Given:

Height of Chelsea = [tex]55\frac{3}{4} inches[/tex]

Height of Carl = Height of Chelsea + [tex]1\frac{3}{8} inches[/tex]

Height of Jane = Height of Carl + [tex]1\frac{1}{5}inches[/tex]

Find:

Height of Jane

Computation:

Height of Carl = Height of Chelsea + [tex]1\frac{3}{8} inches[/tex]

Height of Carl = [tex]55\frac{3}{4} inches[/tex] + [tex]1\frac{3}{8} inches[/tex]

Height of Carl = [tex]57\frac{1}{8} inches[/tex]

Height of Jane = [tex]57\frac{1}{8} inches[/tex] + [tex]1\frac{1}{5}inches[/tex]

Height of Jane = [tex]58\frac{13}{40} inches[/tex]

at a basketball game, 18% were supporting the visiting team. if 2624 people attending supported the home team, what was the total number of people attending the game?

Answers

Answer:

2624= 82%

18%= 2624/82=32. 32*18=576

Step-by-step explanation:

If 2624 people attending supported the home team, the total number

of people attending the game will be 3200.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

It is given that 18% were supporting the visiting team and 2624 people attending supported the home team as a result 82 % were supporting the home team,

Let the total number of people attending the game be x.

⇒82% of x = 2624

⇒(82/100)×x= 2624

⇒x= (2624×100)÷82

⇒x=3200

Hence, if 2624 people attending supported the home team, the total number of people attending the game will be 3200.

How do you find the x intercept and y intercept on a graph and when given an equation?

Answers

Answer:

In a graph, the x-intercept will be the point in which the line crosses the horizontal line of the plane.

The y-intercept is found when the line crosses the vertical line of the plane.

In an equation, y = mx + b, the y-intercept is the value of b, and the x-intercept is shown when y = 0. (substitute y for 0 and find the value of x)

Step-by-step explanation:

Work out the size of angle x.
Not drawn accurately
132°
X Х
54°

Answers

Answer:

x = 84

Step-by-step explanation:

The sum of the angles around a point = 360°

sum the given angles and equate to 360

x + 132 + 54 + 90 = 360

x + 276 = 360 ( subtract 276 from both sides )

x = 84

Answer:

x = 84°

Step-by-step explanation:

→ Recall the fact that angles around a point add up to 360°

360 - (90 + 54 + 132 ) = x

→ Simplify

360 - 276 = x

→ Simplify again

84 = x ∴ x = 84°
