Answer:

Step-by-step explanation:

Answer:

I understand this problem as follows.

We have a bottle (the bottle is empty at the beginning)

Now, as we start to fill the bottle, we do a graph of height vs volume.

Where height is the height of the liquid inside the bottle, and volume is the volume of liquid inside the bottle.

suppose that here you need a volume V to reach a height H.

Now, if we increase the width of the bottle, we are increasing the volume of the bottle.

This means that we should pour a larger volume of liquid to reach the same height as before.

V' = V + d, to reach the same height H.

Then the steepness of the graph decreases.

Answer:

x = -22/3, y = -17/2

Step-by-step explanation:

Answer:

1. Frame 1 to Frame 2 - Vertical downward translation

2. Frame 2 to Frame 3 - [tex]90^{0}[/tex] counterclockwise rotation

3. Frame 3 to Frame 4 - Vertical upward translation

Step-by-step explanation:

The movement of the shapes from one frame to the other can be described by solid transformations. These are procedures required to change the orientation or size of a given shape. They include: rotation, translation, dilation and reflection.

1. When the shape in frame 1 is translated vertically downwards, it would produce the shape in frame 2.

2. Rotating the shape in frame 2 by [tex]90^{0}[/tex] counterclockwise would move it to the shape in frame 3.

3. Vertical upward dilation would move the shape in frame 3 to that in frame 4.

Answer:

x + y = -13

Step-by-step explanation:

The equation of a line is y=mx+c

Line x+3y-9=0

Let's rearrange.

3y= -x+9

Divide both sides by 3.

3y/3 = -x/3 +9/3

y= -x/3 + 3

The gradient is the coefficient of x which is -1/3.

Therefore, m1 = -1/3

Where m1 is the gradient of the first line.

When two lines are parallel, their gradients are equal.

Therefore m1=m2

Where m2 is the gradient of the second line.

Therefore m2=-1/3

Now, we need to find c.

(2,-5)

Here, x=2, y=-5

y=mx+c

-5 = -1/3(2) + c

-5 = -2/3 + c

-5 + 2/3 = c

This can also be written as...

c = -5 +2/3

The LCM is 3.

The addition will give -13/3.

Now, let's create the equation We have m2 and c.

y = mx + c

y = -1/3(x) + (-13/3)

Take note of the signs, (+), and (-).

y = -x/3 - 13/3

Multiply both sides by 3 to remove the denominators.

(3)y = (3)-x/3 - (3)13/3

y = -x - 13

Or

x + y = -13

I hope you understand. Please give brainliest, thank, and rate 5 stars. thanks.

Answer:

[tex]a=10[/tex]

Step-by-step explanation:

Equation 1:  [tex]2a+3b=-1[/tex]

Equation 2: [tex]4a+2b=26[/tex]

Subtract 3b from both sides in Equation 1:

[tex]2a=-1-3b[/tex]

Divide both sides by 2:

[tex]\frac{2a}{2}=-\frac{1-3b}{2}[/tex]

[tex]a=\frac{-1-3b}{2}[/tex]

Substitute this into Equation 2:

[tex]4* \frac{-1-3b}{2}+2b=26[/tex]

[tex]2\left(-3b-1\right)+2b=26[/tex]

[tex]-6b-2+2b=26[/tex]

[tex]-4b-2=26[/tex]

Add 2 to both sides:

[tex]-4b=28[/tex]

Divide both sides by -4:

[tex]\frac{-4b}{-4}=\frac{28}{-4}[/tex]

[tex]b=-7[/tex]

We know that [tex]a=\frac{-1-3b}{2}[/tex]. Plug in b = -7 value:

[tex]a=\frac{-1-3\left(-7\right)}{2}[/tex]

[tex]a=\frac{-1+3\cdot \:7}{2}[/tex]

[tex]a=\frac{20}{2}[/tex]

[tex]a=10[/tex]

Answer:

There is something called "criteria of congruence for triangles".

Those criteria say that, with some data of the triangles, we can know if the triangles are equivalent.

For example one of the criteria is SSS.

Side-side-side.

This means that all the triangles with equal side length for all their sides are equivalent.

So if the information that we give to the factory is the side length of the 3 sides of the triangle, the triangle will be well defined.

Following those criteria, the other 2 options can be:

SAS

Side-Angle-Side

(so you can give the length of two sides and the angle between them)

ASA

Angle-Side-Angle.

(You can give the value of two angles and the length of the side between those two angles)

Answer:

9/10

Step-by-step explanation:

the rule says

[tex]\frac{a}{b} /\frac{c}{d} =\frac{ad}{bc}[/tex]

so in our case

a=3

b=4

c=5

d=6

so the division is

[tex]\frac{3*6}{4*5} \\\\=\frac{18}{20}[/tex]

we can simplify

[tex]\frac{18}{20} \\\\=\frac{2(9)}{2(10)} \\\\=\frac{9}{10}[/tex]

that's our answer

I don't know if you need step by step of the rule, if you need let me know

The division of the fractions are solved and A = 9/10

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the numerator of the fraction be p

where the value of p =  ( 3/4 )

Let the denominator of the fraction be q

where q = ( 5/6 )

Now , the fraction is A = p/q

On simplifying the expression , we get

So , the left hand side of the equation is equated to the right hand side by the value of p/q

A = ( 3/4 ) / ( 5/6 )

A = ( 3/4 ) x ( 6/5 )

On further simplification , we get

A = ( 18 / 20 )

A = 9/10

Therefore , the value of A = 9/10

Hence , the fraction is A = 9/10

Answer:

f(x) = 3.7x + 3

Step-by-step explanation:

Using the fact that y = f(x), then rearrange the equation making y the subject.

- 3.7x = 3 - y ( add y to both sides )

y - 3.7x = 3 ( add 3.7x to both sides )

y = 3.7x + 3 , that is

f(x) = 3.7x + 3

Answer:

40x30= 1200, 20x15=300, 300/1200= 1/4.

Step-by-step explanation:

You can also visualize it. Imagine a field 40’ long and the boy cut the top 20’ of it but left 20’ of the bottom, he would have cut half of it at this point. Now it’s 30’ wide and he cut the left 15’ of what’s remaining but left the right 15’ uncut. So now there’s a 20’x15’ bottom right corner left uncut. There are 4 sections that are 20’x15’ and he left one out of four uncut, otherwise written as 1/4.

Answer:

Distance-Rate-Time and other Products

In this lesson, we will investigate the relationship between the distance traveled, the rate or speed or travel, and the time that it takes to travel that distance at that rate. We will also look at a few other related products.

Distance = (Rate)(Time)

The equation that relates distance, rate, and time is

d = rt

Where d is the distance traveled, r is the rate, and t is the time. On the CAHSEE exam, you will be given two of these and will be asked to use the above equation to find the third.

Example 1

It took Markus half an hour to drive home from work. He averaged 34 miles per hour. How far does Markus live from his work?

Solution

We are given that it takes 1/2 an hour for the trip. This is a time:

t = 1/2

We are given that he averages 34 miles per hour. This is a rate:

r = 34

We are asked how few he has traveled. This is a distance. We use the d=rt equation:

d = rt

= (34)(1/2)

= 17

Markus lives 17 miles from work.

Now try one by yourself. If you want to see the answer, put your mouse on the yellow rectangle and the answer will appear.

Exercise 1

The current along the beach is moving towards the south at 1.5 miles per hour. If a piece of debris is placed into the water, how far will the current take it in 6 hours?

9 miles

Example 2

Elena always rides her bicycle at a speed of 15 miles per hour. On Sunday, she goes on a 24 mile bike ride. How many hours does this ride take?

Solution

The speed of 15 miles per hour is a rate. The key words that tell us that this is a rate are "speed" and "miles per hour". We can write:

r = 15

Next, 24 miles is a distance. We have:

d = 24

Now use the d=rt equation to get

24 = 15t

To solve this, divide both sides by 15 to get

t = 24/15

Both are divisible by 3, so this fraction reduces to

t = 8/5 = 1.6

Elena's ride takes 1.6 hours.

Answer: $7

Step-by-step explanation:

Let x = Cost of each T-shirt.

As per given,

Total charge  =( Number of t shirts x Cost per t shirt )+ set up fee  

For 21 T-shirts , total charge would be : 21x+40  

According to the question

⇒21x+40=187

⇒21x = 187-40

⇒21x = 147

⇒x= 7

Hence, each T-shirt costs $7 .
