Answer:

Step-by-step explanation:

You need to set up a ratio for the original recipe and then use that ratio for the new one.

 

If we need 3 cups of flour for every 4 cups of sugar, we have a 3 c flour/4 c sugar ratio, or 3/4

 

The new ratio is 9 c of flour for ? c of sugar. Those ratios have to be the same, so we set up an equation like this:

 

3/4 = 9/?

 

In order to keep the same ratio, you have to multiply by the same number. Since 3*3 = 9, multiply 4*3 to get your answer.

The centers of Marathon County, Bayfield County, and Dodge County all lie along a straight road. If Marathon County is equidista
il63 [147K]

Answer:

<em>The distance from Bayfield County to Dodge County is 974 miles.</em>

Step-by-step explanation:

Definition of equidistant: equal distance.

Bayfield                                            Marathon                                        Dodge

       +---------------------------------------------+---------------------------------------------+

                            487 miles                                         487 miles

The three centers of the counties lie along a straight line. Since Marathon County is equidistant from Bayfield County and Dodge County, then Marathon County is exactly at the midpoint of the segment from Bayfield County to Dodge County. The distances from Bayfield County to Dodge County and from Marathon County to Dodge County are equal. The distance from Bayfield County to Dodge County is

distance = 487 miles + 487 miles = 974 miles

Thank you very much anh you

Hello from MrBillDoesMath!

Answer:

See discussion below

Discussion:

#4

The sum of the interior angles of a polygon of n sides is (n-2)* 180. As the polygon in #4 has 7 sides , the sum of the interior angles is (7-2)*180 = 5 * 180 = 900.

We can also compute the sum of the interior angles by adding up each of the angles (expressed in terms of x)  shown in #4. Starting at the top of the polygon and proceeding counterclockwise gives:

900 =  (8x +34) + (10x+21)+(9x+30)+(7x+45)+(5x+44)+(12x+13)+(6x+29)  =>

           (8x + 10x+9x+7x+5x+12x+6x) + (34+21+30+45+44+13+29)  =

           57x                                            + 216

This simplifies to

900 =  57x + 216                => subtract 216 from both sides

900-216 = 57x                    => 900-216= 684

684= 57x                            => divide both sides by 57

684/57  = x                         => as 684/57 = 12

x = 12

The diagram has makes repeated use of the same variable for vertices. That is, the diagram shows 4 P's, 1 Q, 2 R's, 0 S's, and 1 T making it impossible to determine the values of some angles.  For example, consider m RST -- whatever that means.

#5 uses the same ideas but the vertices are properly  labeled (I'll leave the grunt of determining the  individual angles to you but here are the main points).

Sum of interior angles = (7 -2) * 180 = 5 * 180 = 900.

900 =  (8x+62) + (7x+66)+(5x+83)+(6x+55)+(10x+42)+(8x+45)+(4x+67)  =>

900 =   (8x + 7x +5x+6x+10x+8x+4x) + (62+66+83+55+42+45+67)

900=     48x                                        +  420             =>

900 -420 = 48x                                                          =>   subtract 420

480  = 48x                                                                  =>   divide by 48

x = 480/48 = 10

Thank you,

MrB

To increase an amount by 5.4% what single multiplier would you use
Rama09 [41]
I would use the decimal form of 5.4%. It is very easy to convert a percentage into a decimal. All you have to do is move the decimal point two places to the left and remove the % sign.

5.4% = 0.054

So, 0.054 would be your multiplier.
