[tex] w \ge 300g + 1000 [/tex]

Step-by-step explanation:

weight of empty crate = 1000 grams

weight of an orange = at least 300 grams

That means that the weight of an orange is equal to or greater than 300 grams.

Weight of g oranges = at least 300g

Total weight of crate and oranges = w

[tex] w \ge 300g + 1000 [/tex]

Answer:

84 arrangements

Step-by-step explanation:

First, we need to calculate the total number of roses that the shop owner has. We do this by adding the pink roses and the red roses that the owner has.

342 + 330 = 672 total roses

Now that we have the total number of roses we simply divide by the number of roses needed for each arrangement (8) in order to calculate the total number of arrangements that the owner can make.

672 / 8 = 84 arrangements

Answer:

B. 1

Step-by-step explanation:

The slope is calculated by taking the difference in the y-coordinates of two points and dividing that by the difference in the x-coordinates of those two points.

Here, we have (6, -12) and (15, -3).

The difference in the y-coordinates is:

15 - 6 = 9

The difference in the x-coordinates is:

-3 - (-12) = -3 + 12 = 9

Divide 9 by 9:

9/9 = 1

The slope is thus 1, and the answer is B.

Answer: is x = -8

this is how i got it ______

6 x - 3 - 11 - 8 x = 2

(simplify both sides and combine like terms)

(6x + -8x ) + ( -3 + -11) = 2

- 2x  +  -14 = 2

-2x  -  14 = 2

( then you add 14 to both sides)

- 2x - 14 = 2

     +14       +14

-2x = 16

( then you divide both sides by -2)

-2x / -2   =   16/ -2

x = -8

ta da!! happy to help!

it made it here. this is for the second one.

( first, we subtract 8n from both sides)

13n + 26 = 8n - 29

-8n           -8n

5n + 26  =  -29

( then we subtract 26 from both sides)

5n + 26 = -29

     - 26    -26

5n = - 55

(after that we divide both sides by 5, we do this to make n alone )

5n/ 5 = -55/ 5

n = -11

Step-by-step explanation:

(-2,-5)

Given:

Lee drew five rectangles as shown on this coordinate grid .

To find:

The correct statement.

Solution:

From the given diagram, it is clear that,

Dimensions of rectangle x are 6 by 3 units.

Dimensions of rectangle A are 7 by 3 units.

Dimensions of rectangle B are 6 by 3 units.

Dimensions of rectangle C are 3 by 6 units.

Dimensions of rectangle D are 6 by 4 units.

Dimensions of rectangle x and B are same and clearly it can be translation or rotation about the origin.

Dimensions of rectangle x and C are same but only rotation is not sufficient to get rectangle C from rectangle x.

Dimension of rectangle x, A and D are different, so they are not congruent and we cannot get rectangle A and D by rotation, reflection and translation.

Therefore, the correct option is B.

Answer:

The slope is 1/2

Step-by-step explanation:

y²-y¹/x²-x¹

=5-3/5-1

=2/4

=1/2

Step-by-step explanation:

The best way to solve these is by making them into a equation, rise over run, or y over x.

[tex] \frac{3}{1} - \frac{5}{5} [/tex]

You will get the same answer nomatter which order these are values are in. Now, solve for this equation.

[tex] \frac{ - 2}{ - 4} [/tex]

Now this is negative and kind of messy, although, we can turn both values into positive values without the answer changing, just be careful on other problems with this technique as it doesn't always work.

[tex] \frac{2}{4} [/tex]

Now we can simplify again.

Answer:

Slope is 1/2

Step-by-step explanation:

Slope Formula = m = y2 - y1/x2 - x1

Point = (4,2) and (10,5)

m = y2 - y1/x2 - x1

m = 5 - 2/10 - 4

m = 3/6

m = 1/2

Hi there!

[tex]\large\boxed{g(f(x)) = 108x^{2} - 156x + 46}[/tex]

f(x) = 6x - 4

g(x) = 3x² - 2x - 10

To find (g(f(x)), substitute in the equation of f(x) as 'x' in g(x):

g(f(x)) = 3(6x - 4)² - 2(6x - 4) - 10

Simplify:

= 3(36x² - 48x + 16) - 2(6x - 4) - 10

= 108x² - 144x + 48 - 12x + 8 - 10

= 108x² - 156x + 46

Step-by-step explanation:

Given

Divide by the following:

(a) 3x² + 2x + 1

Quotient = 2x, remainder = -3x + 5

(b) x³ - 3x + 2

Quotient  = 6, remainder  = 4x² + 22x - 7

(c) 6x² + x - 2

Quotient  = x, remainder = 3x² + x + 5

Using the concept of combination, the value of the expression 9C4 is 126

Recall the combination formula :

[tex]9C4 = \frac{9!} {(9-4)!4!} [/tex]

[tex]9C4 = \frac{9 \times 8 \times 7 \times 6} {4 \times 3 \times 2 \times 1} [/tex]

[tex]9C4 = \frac{3024} {24} = 126 [/tex]

Therefore, the value of the expression 9C4 is 126.

Answer:

What the equation is telling us is that after opening for 1 hour 15 minutes, there were 28 visitors

Step-by-step explanation:

The function we are given is ;

V(1.25) = 28

what this mean is that the number of visitors in the museum after 1.25 hours of opening is 28

1.25 hours is same as 1 hour (0.25 * 60) minutes

What is in the bracket is trying to convert the 0.25 hours to minutes

Since 1 hour is 60 minutes, 0.25 will be (0.25 * 70)

Which is 1 hour 15 minutes

So after opening for 1 hour 15 minutes, the museum had 28 visitors

A statement is convert into the equation by keeping the conditions equal in the form of expressions.

The given function tells that, in 1 hour, 15 minutes of the number of visitors, visit the museum is 28.

Given:

An elephant drinks 49 gallons of water per day.

A rhinoceros drinks 21 gallons of water per day.

To find:

The total amount of water the animals will drink in 8 days.

Solution:

In each day,

Elephant drinks = 49 gallons

Rhinoceros drinks = 21 gallons

Total amount of water they will drink each day is

[tex]49+21=70[/tex]

They will drink 70 gallons in each days.

So, total amount of water the animals will drink in 8 days is

[tex]8\times 70=560[/tex]

Therefore, they will drink 560 gallons of water in 8 days.

Answer:

Step-by-step explanation:

First let us get the slope of the line PQ and RS

For PQ;

Given P(6, -2) and Q(-2,8)

slope m = 8-(-2)/-2-6

slope of pQ = 10/-8

slope of PQ = -5/4

For RS

R ( − 4 , 3 ) and S(-9, y)

slope of RS = y-3/-9+4

slope of RS = y-3/-5

For PQ to be perpendicular to RS, the product of their slope must be -1

Hence -5/4 (y-3/-5) = -1

y-3/4 = -1

cross multiply

y-3 = -4

y = -4+3

y = -1

Hence the value of y for PQ to be perpendicular to RS is -1
