Answer:

20*6 - 120

20*6 = 120

19 * 6 = 114

Step-by-step explanation:

Call x the scale factor.

20x + 19x + 20x = 354       Add the left side together.

59x = 354                           Divide by 59

59x/59 = 354/59                Combine and cancel

x = 6

The lengths of the sides are

20 * 6 = 120

19 * 6 =  114

20 * 6 = <u>120</u>

Total    354 Check

Polygon stuv is reflected over the x axis and then over the y axis to create wxyz . Which of the following sides are congruent ?
JulsSmile [24]

Answer:

ST and WX are congruent ⇒ first answer

Step-by-step explanation:

∵ S = (-5 , -4) , T = (-3 , -1) , U = (-1 , -3) , V = (-2 , -6)

∵ STUV reflected over the x-axis

∴ S' = (-5 , 4) , T' = (-3 , 1) , U' = (-1 , 3) , V' = (-2 , 6)

∵ S'T'U'V' reflected over the y-axis

∴ S" = (5 , 4) , T" = (3 , 1) , U" = (1 , 3) , V" = (2 , 6)

∵ W = (5 , 4) , X = (3 , 1) , Y = (1 , 3) , Z = (2 , 6)

∴ S"T"U"V" is WXYZ

∴ ST and WX are congruent

For a specific location in a particularly rainy city, the time a new thunderstorm begins to produce rain (first drop time) is un
kicyunya [14]

Answer:

c) 0.0871

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X between c and d is given by the following formula.

P(c \leq X \leq d) = \frac{d - c}{b - a}

On a single day:

24 hours, so a = 0, b = 24

8:25 P.M. is 8:25 = 8.4167h

3:30 P. M. is the equivalent to 12 + 3:30 = 15:30 = 15.5h

Probability of rain between these times:

P(8.4167 \leq X \leq 15.5) = \frac{15.5 - 8.4167}{24 - 0} = 0.2951

On both days:

Two days, each with a 0.2951 probability

0.2951*0.2951 = 0.0871

The correct answer is:

c) 0.0871
