State if the two triangles are congruent. if they are state how you know.
nlexa [21]
1) The triangles are congruent by SSS.

The two tick marks indicate two pairs of congruent sides; it is evident that the third side is congruent by the way the diagram is drawn - the bases of the triangles are together and appear to be the same length.

2) The triangles are congruent by SAS.

The two pairs of tick marks indicate congruent sides, and their included angles are congruent because they are vertical angles, and vertical angles are always congruent.

4.67,4.98,4.34 minutes what is the standard deviation for these three songs
ValentinkaMS [17]
First compute the mean:

(4.67 + 4.98 + 4.34) / 3 = 4.66

then compute the variance:

(4.67-4.66)^2 = 0.0001
(4.98-4.66)^2 = 0.1024
(4.34-4.66)^2 = 0.1024

sum of the three = 0.2049

then take the square root:

= 0.452

the standard deviation is 0.452

Doming ran a total of 4 miles not 4.75. This is because if we take away the 6 minutes of walking, it will be 32 minutes left of just running, and if he is going exactly 8 minutes per mile then he ran 4 miles in total.

Juanito looked out the window and saw 20 bicycles and skateboards. There were a total 52 wheels. How many of each did he see , s
andriy [413]

Answer:

Let's denote:

x: number of bicycles

y: number of  skateboards

Then, we have:

x + y = 20

2x + 4y = 52

=> 2(20 - y) + 4y = 52

=> 2y = 12

=> y = 6 (number of skateboards)

=> x = 14(number of bicycles)

Hope this helps!

:)
