[tex]\\ \rm\rightarrowtail 1/9(1/3)[/tex]

[tex]\\ \rm\rightarrowtail 1/9(3)[/tex]

[tex]\\ \rm\rightarrowtail 1/27[/tex]

Answer:

d 1/27

Step-by-step explanation:

Using the flip and multiply method:

      [tex]\sf \dfrac{1}{\dfrac{9}{3}}[/tex]

[tex]\sf \implies \dfrac19 \div 3[/tex]

[tex]\sf \implies \dfrac19 \div \dfrac31[/tex]

[tex]\sf \implies \dfrac19 \times \dfrac13[/tex]

[tex]\sf \implies \dfrac{1 \times 1}{9 \times 3}[/tex]

[tex]\sf \implies \dfrac{1}{27}[/tex]

Answer:

A

Step-by-step explanation:

215.80 + 215.80 = 431.60

36.50 + 36.50  = 73

431.60 + 73 = 504.60

2560 - 504.60 = 2055.40

The correct statement is:

Gabrielle and Rob have $2,055.40 of the $2,560 left because 2,560 − 2(215.80) − 2(36.50) is equal to 2,055.4.

Option A is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Gabrielle and Rob's total earnings for the week are $2,560.

If Gabrielle buys 2 train tickets that cost $215.80 each.

She spends a total of:

\$431.60 (2 x 215.80).

If Rob buys 2 suitcases that cost $36.50 each, he spends a total of:

$73 (2 x 36.50).

To find out how much money they have left, we need to subtract the amount spent on tickets and suitcases from their total earnings:

$2,560 - $431.60 - $73

= $2,055.40

Therefore,

The correct statement is:

Gabrielle and Rob have $2,055.40 of the $2,560 left because 2,560 − 2(215.80) − 2(36.50) is equal to 2,055.4.

I'll help you! Answer is 3/2. It's Friday so most people aren't on Brainly doing homework lol

Step-by-step explanation:

The heaviest bag (far right) weighs 4.75 lbs, whereas the lightest bag (far left) weighs 3.25 lbs. As mixed numbers, these would be [tex]4\frac{3}{4}[/tex]  and [tex]3\frac{1}{4}[/tex]. To find how much heavier the 4.75 lb bag is, you must subtract the 2 numbers.

[tex]4\frac{3}{4}[/tex]  =   [tex]\frac{19}{4}[/tex]

[tex]3\frac{1}{4}[/tex]  =  [tex]\frac{13}{4}[/tex]

[tex]\frac{19}{4} - \frac{13}{4} =\frac{6}{4}[/tex]

[tex]\frac{6}{4} =\frac{3}{2}[/tex]  

Given -

To find -

Concept -

Whenever two parallel lines are cut by a transversal, an interesting relationship exists between the two interior angles on the same side of the transversal. These two interior angles are supplementary angles. Hence, according to the figure l and m are two parallel lines and t is the transversal intersecting them then ∠1 + ∠2 = 180°.

Solution -

[tex]\rightarrow\sf{(13x+24)^{ \circ}+(5x-6)^{ \circ}=180^{ \circ}}[/tex]

[tex]\rightarrow\sf{13x+5x+24-6=180}[/tex]

[tex]\rightarrow\sf{18x+18=180}[/tex]

[tex]\rightarrow\sf{18x+18=180}[/tex]

[tex]\rightarrow\sf{18(x+1)=180}[/tex]

[tex]\rightarrow\sf{x+1=\frac{180}{18}}[/tex]

[tex]\rightarrow\sf{x+1=10}[/tex]

[tex]\rightarrow\sf{x=10-1}[/tex]

[tex]\rightarrow\boxed{\bf{x=9}}[/tex]

m∠2 = (5x-6)° = {5(9) - 6}° = {45 - 6}°= 39°

Henceforth, m∠2 = 39°

Step-by-step explanation:

To find the constant of proportionality between y and x, divide  [tex]\frac{y}{x}[/tex] for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.

In order to find the diameter, we need to multiply the radius times 2, because the radius is one half ([tex]\displaystyle\frac{1}{2} }[/tex]) of the diameter.

We are given that the radius is:-

Multiply it times 2:-

[tex]\bigstar{4~in}[/tex]

Answer:

First, set up equations for total cost for both Happy Paws and Woof Watchers.

x= number of hours

y= total cost

Happy Paws

y=3.50x +16

Woof Watchers

y=4.75x+11

4.75x+11=3.50x+16

x=4

You can check your answer by doing the following:

Happy Paws: (3.50)(4)+16= 30

Woof Watchers: (4.75)(4)+11= 30

Answer:

6

Step-by-step explanation:

Using the Triangle Inequality Theorem, we can derive the range in which the third side, x. If you are having trouble with the theorem, it is that the sum of any two sides must be larger than the other side.

4 + 9 > x => x < 13

x + 4 > 9 => x > 5

x + 9 > 4 => x > -5

Combining all three equations gives us 5 < x < 13

Since the number is a whole number, the smallest whole number that satisfies the range is 6. The answer is 6.

Answer:

235 square centimeters

Step-by-step explanation:

Split The Shape Into 2.

Shape 1: 11 cm by 14 cm

11 cm * 14 cm = 154 square centimeters

Shape 2: (20 - 11) cm by 9 cm

(20 - 11) cm * 9 cm = 9 cm * 9 cm = 81 square centimeters

Original Shape = Shape 1 + Shape 2

154 + 81 = 235 square centimeters

Answer:

[tex]3300ft^{3}[/tex]

Step-by-step explanation:

For this problem it is easier to split it up into two shapes. One being the big box(1) on top and the other being the small box(2) below it.

Volume of box 1:

[tex]Volume = length*width*height[/tex]

[tex]Volume of Box 1 = 25ft*(20+4)ft*5ft = 3000ft^{3}[/tex]

Volume of box 2:

[tex]Volume = length*width*height[/tex]

[tex]Volume of Box 2 = 25ft*4ft*(8-5)ft=300ft^{3}[/tex]

Total volume:

[tex]Total Volume = Volume of Box 1 + Volume of Box 2 = 3000ft^{3}+300ft^{3} = 3300ft^{3}[/tex]

The volume of the figure, by splitting it into two cuboids comes to be 3300 ft³.

Let us split the given figure into two cuboids

The dimensions of one cuboid = 20 ft*25 ft *5ft

The dimension of the other cuboid = 4 ft*25ft * 8ft

So, the volume of the figure will be the sum of the volume of both the cuboids.

The volume of a cuboid is the product of its three dimensions i.e. length, breadth, and height.

So, the volume of the cuboid with dimensions 20 ft*25 ft *5ft

= 20*25*5

=2500 ft³.

The volume of the cuboid with dimensions  4 ft*25ft * 8ft

=4*25*8

=800 ft³.

So, the volume of the figure = 2500 + 800 =3300 ft³.

Therefore, the volume of the figure, by splitting it into two cuboids comes to be 3300 ft³.

Answer: 45%.

Step-by-step explanation: When you solve problems like these, you need to make the total 100%.  The total amount of people at the community pool is 120.  120 can be our 100%.  66 people aren't in the water and 54 are in the water.  As you can see, less than half of the total number of people at the community swimming pool is in the water, which means that is 45%.  The 66 people who aren't in the water are 55% of the total people that are at the community swimming pool.  So in summary, 45% of the total people who are in the community swimming pool are in the water.
