A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 5 large boxes and 3 small boxes has a total weight of 135 kilograms. A delivery of 7 large boxes and 9 small boxes has a total weight of 255 kilograms. How much does each type of box weigh?

Answer:

(x-4)² -11 where a = 4, b = 11

Step-by-step explanation:

The final form (x-a)² - b evaluates to x² - 2ax + a² -b

Matching

x² - 8x    +  5    

x² - 2ax  +  a² -b

This gives us -2ax = -8x or -2a = -8 or a = 4

and a² - b = 11 ==> 16 - b = 11 or b =5

Rewritten form is

(x-4)² -11

Answer:

540°

Step-by-step explanation:

Formula: note that n means nr of sides

(n-2)×180°

(5-2)×180°=3×180=540°

Where each angle are 540°÷5=108°

Answer:

540

Step-by-step explanation:

108 is one interior angle from a regular pentagon

And a pentagon has 5 interior angles

So 180x5=540

Answer:

b = -4, 0

Step-by-step explanation:

Given :

Take b as a common factor.

Solutions

Answer:

b = - 4, b = 0

Step-by-step explanation:

b² + 4b = 0 ← factor out b from each term

b(b + 4) = 0

equate each factor to zero and solve for b

b = 0

b + 4 = 0 ⇒ b = - 4

Answer:

(x-3)*(4x+1)

Step-by-step explanation:

Factoring  4x2-11x-3

The first term is,  4x2  its coefficient is  4 .

The middle term is,  -11x  its coefficient is  -11 .

The last term, "the constant", is  -3

Step-1 : Multiply the coefficient of the first term by the constant   4 • -3 = -12

Step-2 : Find two factors of  -12  whose sum equals the coefficient of the middle term, which is   -11 .

     -12    +    1    =    -11    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -12  and  1

                    4x2 - 12x + 1x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

                   4x • (x-3)

             Add up the last 2 terms, pulling out common factors :

                    1 • (x-3)

Step-5 : Add up the four terms of step 4 :

                   (4x+1)  •  (x-3)

            Which is the desired factorization

Final result :

 (x - 3) • (4x + 1)

Answer:

[tex](4x+1)(x-3)[/tex]

Step-by-step explanation:

[tex](4x+1)(x-3)=4x^{2} +x-12x-3=4x^{2} -11x-3[/tex]

Answer:

(2,2)

Step-by-step explanation:

coordinates are written as (x,y)

where x represents the x value of the coordinate and y represents the y value of the coordinate.

If we look at the graph we can tell that "b" has an x value of 2 and a y value of 2

Therefore we can say that "b" is positioned at (2,2)

Answer:

C. (2, 2)

Step-by-step explanation:

A coordinate is used to identify a point on a graph. A coordinate is written in the form of (x, y), where x is the x-value and y is the y-value.

The x-value is the number of units left or right from the origin (0, 0), and it gets negative by going left and positive by going right.

The y-value is the number of units up or down from the origin (0, 0), and it gets negative by going down and positive by going up.

For example, the coordinates (1, -2) indicate that the x-value goes to the right one unit and the y-value goes down two units.

Here, we are asked to find the coordinate of B:

Therefore, the correct answer is C. (2, 2)

Answer:

A layer of granite

Step-by-step explanation:

This layer so granite is impervious hence is not porous. Due to its non-porosity, water cannot pass through it. These types of rocks are important in aquifers. When an impervious rocks sandwich a pervious layer or are below a pervious rock, an aquifer is created.

The type of material did the water most likely encounter when it stopped is, ''A layer of granite''.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Since, We get;

An igneous rock which is formed by the cooling of a molten body of rock and more cooling of the molten body of rock (magma) is a Granite. The surrounding rock is more dense than the the body of molten material and they rise in form of bulb shaped known as plugin.

After rising, the granite slowly cools down, visible crystals that makes up layers are formed during the slow cooling process.

Water hardly penetrate through a layer of granite because of it's dense nature. The layers of granite prevent the vertical movement of water.

In this case water pass through the layer of rock because it is less dense, but it can't pass through a layer of granite because it is very dense and if forms a bulb(onion) like shape.

Thus, The type of material did the water most likely encounter when it stopped is, ''A layer of granite''.

Answer:

Looking at the problem we come across one issue where we have two minus signs.  However, this issue can be fixed because for example if we multiply -1 by -1 we would just get 1.  Therefore these two minus signs cancel out and we put a plus sign so our problem becomes -7 + 13.  Now we just combine and we get 6.

Using the relation between velocity, distance and time, it is found that her average speed for the final 30 miles is of 55.56 mph.

Velocity is distance divided by time, that is:

[tex]v = \frac{d}{t}[/tex]

Simone travels 90 miles at an average speed of 40 mph, hence the time is given by:

[tex]t_1 = \frac{90}{40} = 2.25[/tex]

She then travels a further 30 miles, with an average speed for the journey of 43 mph. Hence, she traveled 90 + 30 = 120 miles, and the total time is given by:

[tex]t = \frac{120}{43} = 2.79[/tex]

Hence, in the second part, she traveled 30 miles in 2.79 - 2.25 = 0.54 hours, so the velocity is given by:

[tex]v = \frac{d}{t} = \frac{30}{0.54} = 55.56[/tex]

Her average speed for the final 30 miles is of 55.56 mph.

Answer:

The correct answer is 8.8 units

Step-by-step explanation:

I just got it correct.

Answer:

A

Step-by-step explanation:

The point-slope form the line which has the value of slope -5 and contains a point as A(2,-1) is (y+1)=-5(x-2).

The point slope  form of a line is the expression of line which has a specified slope and passes through a point.

The point slope form is givne as,

(y-y₁)=m(x-x₁)

Here, m is the slope of the line, x₁ is the x coordinate of the point by which line passes and y₁ is the y coordinate of the same point.

The slope of a line is -5. This line contains the point A (2,-1). Thus, the point slope form is,

(y-y₁)=m(x-x₁)

(y-(-1))=-5(x-2)

(y+1)=-5(x-2)

Thus, the point-slope form the line which has the value of slope -5 and contains a point as A(2,-1) is (y+1)=-5(x-2).

The empirical rule states that for a normal distribution, about 68% are within one standard deviation from the mean, 95% are within two standard deviation from the mean and 99.7% are within one standard deviation from the mean

Given a mean of 1150 pounds and a standard deviation of 22 pounds. Hence:

Answer:

75 more girls.

Explanation:-

Given:- Ratio of girls to boys = 5:3

And, the number of boys= 300

Let boys be 4x and girls be 5x

So, 4x = 300 (Given)

x = 300/4 = 75

Thus number of girls:- 5x = 5×75= 375 girls

now you take the 375 girls minus the 300 boys.

375-300 = 75 Girls more

Answer:

Part A answer: 0.5x + 3 = 18.50
How I got the answer: 0.5 means how much money she made from each cup. the variable x = how many she sold. 3 equals the tip from the neighbor. and 18.50 is the total price

Part B answer: (0.75x - 0.10x) + 3 = 21.00
How i got the answer: 0.75 is how much money she make from each cup. 0.10 means how many she paid for each cup she used. x = how many cups were sold/bought (should be the same number!). 3 is the tip. and 21.00 is the total price made.

Part C answer: The equations differ because Sydney didn't have to pay for the cups she used, while Daria did. Although they did have the same amount for a tip, Daria made more money than Sydney.
