____ [38]

<h3>There are 135 bottles in all</h3>

Solution:

Given that,

A truck is carrying grapefruit juice, mango juice and orange juice bottles in a ratio of 1:1:7

Ratio = 1 : 1 : 7

Let the number of grape fruit juice bottles be 1x

Let the number of mango juice bottles be 1x

Let the number of orange juice bottles be 7x

There are 105 orange juice bottles

Therefore,

7x = 105

Divide both sides by 7

x = 15

Therefore,

number of grape fruit juice bottles = 1x = 15

number of mango juice bottles = 1x = 15

number of orange juice bottles = 7x = 105

Thus,

Total bottles = 15 + 15 + 105 = 135

Thus there are 135 bottles in all

Today, Isaac needs to walk his dog, water the garden, and feed his fish. DDD is the number of minutes it takes to walk his dog,

yarga [219]

Answer:

The total Minutes of the Inside tasks.-F (Fish)
The total Minutes of the Outside tasks.-G+D (Garden and Dog)
The total Minutes of the tasks involving animals.-D+F (Dog and fish)
The total Minutes of the tasks not involving animals.-G (Garden

Step-by-step explanation:

D is the number of minutes it takes to walk his dog

G is the number of minutes it takes to water the garden

F is the number of minutes it takes to feed his fish.

We are required to match these situations to their respective expressions:

Situation

The total Minutes of the Inside tasks.
The total Minutes of the Outside tasks.
The total Minutes of the tasks involving animals.
The total Minutes of the tasks not involving animals.

Expression

Match:

The total Minutes of the Inside tasks.-F (Fish)
The total Minutes of the Outside tasks.-G+D (Garden and Dog)
The total Minutes of the tasks involving animals.-D+F (Dog and fish)
The total Minutes of the tasks not involving animals.-G (Garden)

Please helpppp :< here is 25 points

masha68 [24]

Answer:

function b

Step-by-step explanation:

When its asking for which function has a greater rate of change its asking for which slope has a greater value

the slope is calculated by change in y over change in x

for function a, as y goes up 2 x goes up 1

so the slope ( rate of change) is 2/1

for function b is y goes up 3 x goes up 1

so the slope (rate of change) is 3/1

3/1 is greater than 2/1 so function b has a greater rate of change

Part 4: Use the information provided to write the vertex formula of each parabola.

sergey [27]

Answer: 1. x = (y - 2)² + 8

$\bold{2.\quad x=-\dfrac{1}{2}(y-10)^2}+1$

3. y = 2(x +9)² + 7

Step-by-step explanation:

Notes: Vertex form is: y =a(x - h)² + k or x =a(y - k)² + h

(h, k) is the vertex
point of vertex is midpoint of focus and directrix: $\dfrac{focus+directrix}{2}$

$\bullet\quad a=\dfrac{1}{4p}$

p is the distance from the vertex to the focus

$focus = \bigg(\dfrac{-31}{4},2\bigg)\qquad directrix: x=\dfrac{-33}{4}\\\\\text{Since directrix is x, then the x-value of the vertex is:}\\\\\dfrac{focus+directrix}{2}=\dfrac{\frac{-31}{4}+\frac{-33}{4}}{2}=\dfrac{\frac{-64}{4}}{2}=\dfrac{-16}{2}=-8\\\\\text{The y-value of the vertex is given by the focus as: 2}\\\\\text{vertex (h, k)}=(-8,2)$

Now let's find the a-value:

$p=focus-vertex\\\\p=\dfrac{-31}{4}-\dfrac{-32}{4}=\dfrac{1}{4}\\\\\\a=\dfrac{1}{4p}=\dfrac{1}{4(\frac{1}{4})}=\dfrac{1}{1}=1$

Now, plug in a = 1 and (h, k) = (-8, 2) into the equation x =a(y - k)² + h

x = (y - 2)² + 8

***************************************************************************************

$focus = \bigg(\dfrac{1}{2},10\bigg)\qquad directrix: x=\dfrac{3}{2}\\\\\text{Since directrix is x, then the x-value of the vertex is:}\\\\\dfrac{focus+directrix}{2}=\dfrac{\frac{1}{2}+\frac{3}{2}}{2}=\dfrac{\frac{4}{2}}{2}=\dfrac{2}{2}=1\\\\\text{The y-value of the vertex is given by the focus as: 10}\\\\\text{vertex (h, k)}=(1,10)$

Now let's find the a-value:

$p=focus-vertex\\\\p=\dfrac{1}{2}-\dfrac{2}{2}=\dfrac{-1}{2}\\\\\\a=\dfrac{1}{4p}=\dfrac{1}{4(\frac{-1}{2})}=\dfrac{1}{-2}=-\dfrac{1}{2}$

Now, plug in a = -1/2 and (h, k) = (1, 10) into the equation x =a(y - k)² + h

$\bold{x=-\dfrac{1}{2}(y-10)^2}+1$

***************************************************************************************

$focus = \bigg(-9,\dfrac{57}{8}\bigg)\qquad directrix: y=\dfrac{55}{8}\\\\\text{Since directrix is y, then the y-value of the vertex is:}\\\\\dfrac{focus+directrix}{2}=\dfrac{\frac{57}{8}+\frac{55}{8}}{2}=\dfrac{\frac{112}{8}}{2}=\dfrac{14}{2}=7\\\\\text{The x-value of the vertex is given by the focus as: -9}\\\\\text{vertex (h, k)}=(-9,7)$
