B. is 12 degrees Farenheit because you just have to convert it, so if you count the lines inbetween 10 and 20 its 4 so it goes by 10,12,14,18,20 then you connect the 10 degrees celcius to the line on farenheit and it matches 12 degrees so thats the answer

Two cars leave towns 750 kilometers apart at the same time and travel toward each other. One car's rate is 20 kilometers
Tanya [424]

Answer:

Step-by-step explanation:

add up their speed.

combined speed = x+ 1 x + 10

( 2 x + 10 )

Time = 5 hours

Distance = 750 miles

Distance = speed * time

( 2 x 10 )* 5 = 750

10 x + 50 = 750

10 x = 750 + -50

10 x = 700

/ 10

x= 70 mph Car A

Car B 70 + 10 = 80 mph

Darina [25.2K]
Percent decrease : (original number - new number) / original number..*100
                            = (225,000 - 191,250) / 225,000.....* 100
                            = 33,750 / 225,000....* 100
                            = 0.15 * 100
                            = 15% decrease <==

) Three sides of a quadrilateral are the same length, q. The length of the fourth side is 7 inches.
Kruka [31]

Answer:

q=(40-7)/3 or simplified q=11

Step-by-step explanation:

So we know that the perimeter is 40 inches and one of the sides is 7 so logically we do 40-7 to get the length of the three remaining sides combined. Then to find the length q, we have to divide that answer by 3 because the three sides have the same length or (40-7)/3, which simplified is 11, so the length of the side is 11 inches and the expression is q=(40-7)/3.

How can you find the area of a polygon that is not for which you know an area formula
kipiarov [429]

Answer:

See below.

Step-by-step explanation:

If it is a regular polygon then you can look up the formula or break it into shapes you do know the formula.

If it is irregular or a composite figure, break it into regular polygons which do have formulas to find the area. Here is an example:

Example:

Find the area of the composite figure by splitting the figure into two shapes - two rectangles.

One rectangle is 2 x 9 = 18.

The other rectangle is 2 x 4 = 8.

Together the area is 18 + 8 = 26.
