Answer:
44 millimeters
Step-by-step explanation:
The ratio is set up as millimeters : meters
On the map, 4 millimeters : 9 meters
The actual length ratio is represented as x millimeters : 99 meters
Since we know its proportional, we can set up the equation:
4/9 = x/99
Solve:
4/9 = x/99
4 * 99 = 9x
396 = 9x
x = 44 millimeters
Another Way
Since we already know it is proportional, 99 = 9 x 11
So we can multiply 4 x 11 to get 44 millimeters.

16. A craft shop sold 150 pillows. Small pillows were $6.50 each and large pillows were $9.00 each. If the total amount collected from the sale of these items was $1180.00, what is the total number of each size pillow that was
sold?
Answers
Answer:
82 large pillows, 68 small pillows
Step-by-step explanation:
Suppose all pillows sold were small pillows:
150×$6.50=$975
$1180-$975=$205
$9-$6.50=$2.50
$205÷$2.50=82 (no of large pillows sold)
No. of small pillows sold

Step-by-step explanation:

You need to find a common denominator.
The common denominator is 36. You have to get all denominators to 36.
How to do that?
Example = [tex]\frac{3}{4} *\frac{9}{9} =\frac{27}{36}[/tex].
Do that to all the fractions.

Answers
Las dos rectas que se cortan formando un ángulo de 135° son secantes. (Opción: C)
Las dos rectas en cuestión no pueden ser paralelas pues sus pendientes son distintas y, por consiguiente, se intersecan en algún lugar del plano.
Tampoco pueden ser semirrectas pues el enunciado indica que existen dos rectas y las rectas no tienen principio ni fin.
Mucho menos pueden ser perpendiculares, pues el ángulo es distinto a 90°.
En consecuencia, las dos rectas que se cortan formando un ángulo de 135° son secantes. (Opción: C)

_____
Additional comment
That is one of the reasons why a coefficient of 1 is (almost) never shown.
In algebra, multiplication can be indicated a number of ways.
ab . . . . placing values next to each other (sometimes with a small space)
(a)(b) . . . . placing values next to each other with either or both in parentheses
a·b . . . . . using a multiplication symbol between the values.
There are several different multiplication symbols in common use:
* — asterisk
· or • — centered dot
× — centered "x" multiplication symbol
x — the lower-case letter x (when it cannot be confused with a variable)
. — a period (when it cannot be confused with a decimal point). This is uncommon in the US, but is seen occasionally when some of the other symbols are not available. It is more common outside the US.

The multiplication of a constant and a variable expression cannot actually be accomplished. It can only be "indicated." If you wanted to multiply 2*w^3, that product would be indicated in any of the ways described above. Perhaps the simplest and least-confusing to most people is ...
2w^3
Multiplying 1*w^3 can be indicated the same way: 1*w^3. In view of the special treatment given to a coefficient of 1, we would not simplify this to
1w^3
Rather, we would simplify it to ...

Answer:
46,145
Step-by-step explanation:

The total length of the marathon race in yards when the length of a marathon race is 26 miles 385 yards, is 46145 yards.
How to measure the length?Length measurement is the measurement of the size of an object. The units of length measurement are meter, feet, yards etc.
Yards-This unit is used when the size of a small space has to measure, such as length of bed, ladder etc. There are total 1760 yards in one mile.Miles-This is the basic unit of length measurement of size. The size of roads, distance between two cities are measured in miles.The length of a marathon race is 26 miles 385 yards. As there are total 1760 yards in one mile. Thus, the total number of yards in 26 miles is,
[tex]26\times1760=45760[/tex]
Now, he races for 385 yards along with 26 miles. Thus, the length of marathon is,
[tex]45760+385=46145\rm\; yards[/tex]
Thus, the total length of the marathon race in yards when the length of a marathon race is 26 miles 385 yards, is 46145 yards.
