Answer:

Marco's boxes weigh 15 lbs.

Step-by-step explanation:

9x + 14(x - 8) = 233

9x + 14x - 112 = 233

23x = 345

x = 15

Answer:

-6/8

Step-by-step explanation:

The rate of change is the same as the slope (I don't know if you have learned that term yet), but basically its the change in y's over the change in x's. to find this out, all you have to do is count from the point on the graph that is the farthest right (in this case, (6,1)), up to the y coordinate of the point farthest to the left (-2, 7) which is 6, and then count the number of spaces between the x coordinates, which is 8. put the rise (up and down count) over the run (horizontal count) in a fraction form, which gives you 6/8, and then notice how the line is pointing towards the bottom RIGHT hand corner making the line negative, so you need to make the rate of change negative, giving you the final answer of -6/8.

In ΔUVW, w = 44 cm, u = 83 cm and ∠V=141°. Find the area of ΔUVW, to the nearest square centimeter.
Tema [17]

Answer:

Area  \approx 1149\ cm^2

Step-by-step explanation:

<u>Given that:</u>

ΔUVW,

Side w = 44 cm, (It is the side opposite to \angle W)

Side u = 83 cm (It is the side opposite to \angle U)

and ∠V=141°

Please refer to the attached image with labeling of the triangle with the dimensions given.

Area of a triangle with two sides given and angle between the two sides can be formulated as:

A = \dfrac{1}{2}\times a\times b\times sinC

Where a and b are the two sides and

\angle C is the angle between the sides a and b

Here we have a = w = 44cm

b = u = 44cm

and ∠C= ∠V=141

Putting the values to find the area:

A = \dfrac{1}{2}\times 44\times 83\times sin141\\\Rightarrow A = \dfrac{1}{2} \times 3652 \times sin141\\\Rightarrow A =1826 \times 0.629\\\Rightarrow A  \approx 1149\ cm^2

So, the <em>area </em>of given triangle to the nearest square centimetre is:

Area  \approx 1149\ cm^2

I need help on 1/2/3/4
vaieri [72.5K]

You may need to sit down with your parents or with your teacher and
go over how to add and subtract fractions.

1).  "Perimeter" means the distance all the way around the square.
With a square, all 4 sides are the same length.  With <u>this</u> square,
every side is 1-1/4 inches long.

Perimeter = length of all 4 sides= (1-1/4) + (1-1/4) + (1-1/4) + (1-1/4) =

                                               (1 + 1 + 1 + 1) + (1/4 + 1/4 + 1/4 + 1/4) =

                                                         4           +             4/4  =  <em>5 inches</em> .

2).  (2-3/8) + (1-7/8) = (2 + 1) + (3/8 + 7/8) =

                                        (3)   +    (10/8) =

                                         3    +      1-1/4 =        <em>4-1/4 .</em>

3).  The difference is  (1-1/6) minus (5/6) .

Before you start to do the subtraction, write the (1-1/6)  as  (7/6) .

Then the subtraction is    (7/6) - (5/6)  =  2/6  =  <em>1/3</em> .

4).  This one is almost the same kind of problem as #3. 
It's another subtraction.

If you need (2-1/4) all together, and you already have (1-3/8),
then the amount you still have to find, or borrow, or buy, is the
difference between those two numbers.

           (2-1/4) minus (1-3/8) .

The trick is to write the (2-1/4) in some form that you'll be able to
subtract (1-3/8) from it.  When I learned how to do that, it was called
'borrowing', but I think now it's called 'regrouping'.

We need to work on (2-1/4):

-- take 1 from the 2, and change it into fourths.
 
                 2-1/4  =  1 and 4/4 and 1/4  =  1 and 5/4

-- Now, take those 5/4, and turn them into eighths.                
   Each fourth makes 2 eighths.  So  5/4  =  10/8.

Now, the (2-1/4) has turned into  1-10/8 .
We did NOT change the value.  It's still the same amount
as 2-1/4 , but it's just written in a different way.
And now the subtraction is easy:

         (2-1/4) minus (1-3/8)  = 

       (1-10/8) minus (1-3/8)  =  (zero and 7/8).

You need  <em>7/8 inch</em>  more string than you already have.
