Answer:

Answer:

x = 127

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6, thus

sum = 180° × 4 = 720°

Sum the interior angles and equate to 720 for x

120 + 100 + 128 + 133 + 112 + x = 720, that is

593 + x = 720 ( subtract 593 from both sides )

x = 127

The value of x is 44.

Given

Equation; $\rm log4(x + 20) = 3$

The value of the x is determined by using the logarithmic properties following all the steps given below.

The value of x is;

$\rm log4(x + 20) = 3$

Taking log base 4 on both sides;

$\rm log4(x + 20) = 3\n\n(x+20) = 4^3\n\nx+20 = 4 * 4* 4\n\nx+20=64\n\nx=64-20\n\nx=44$

Hence, the value of x is 44.

A hose fills a hot tub at a rate of 2.58 gallons per minute. How many hours will it take to fill a 268-gallon hot tub?

Answers

Answer:

1.73 hours

Step-by-step explanation:

This can be solved with proportions.

$(2.58 gallons)/(1 minute) = (268 gallons)/(x minutes) \n$

Cross multiply and you get:

$2.58x gallons * minutes = 268 gallons * minutes\n$

Divide by 2.58 gallons and you get:

$x minutes = (268 gallons)/(2.58 gallons) * minutes \nx minutes = 103.876 minutes\nx = 103.876 minutes\n$

And to find out the number of hours that is, divide by 60 and you get 1.73 hours.

Hope’s mom bakes a cake for hope’s birthday. It is in the shape of a rectangle 10in. long and 6in. wide. If she starts at one corner and puts a candle every 2 inches, how many candles will fit around the edge of the cake?

Answers

Answer:

Step-by-step explanation:

so we know the size of 2 edges or sides of the cake 6in and 10in, in a rectangle the opposite sides are the same, so there are 2 6in and 2 10in sides. add them together (6+6+10+10) to get 32in, now divide that by 2(the spacing of the candle) to get 16 candles around the edge.
