5, 10 and 8 all need to equal the same number for it to be the exact same day. 5, 10, and 8 go into 40

Put the following in order from smallest to largest 1 - 0.29 - 23% - 1 - 0.027

valentinak56 [21]

1 ; 0.29 ; 23% ; 1 ; 0.027 ; 4.5

23% is 0.23

smallest to largest:

0.027 ; 23% ; 0.29 ; 1 ; 1 ; 4.5

If in percentage form, multiply each in 100%

0.027 x 100% = 2.7%
23% already in % form, as is = 23%
0.29 x 100% = 29%
1 x 100% = 100%
4.5 x 100% = 450%

Find the mean of the data set that consists of 3, 11, 4, 3, 10, 6, 4, 5.

sdas [7]

Answer:

5.75

Step-by-step explanation:

$3 + 11 + 4 + 3 + 10 + 6 + 4 + 5 = 46 \\ 46 \div 8 = 5.75$

The total amount of numbers are : 8

To find the mean, we calculate the sum of all values and divide that sum by the amount of numbers there are.

△STU is an equalateral triangle, if ST is one less than twice x, SU Is 37 less than 5 times x, and TU is 11 more than x, find x

miskamm [114]

Answer:

x = 12, sides = 23

Step-by-step explanation:

$\overline{ST}=2x-1\\\overline{SU}=5x-37\\\overline{TU}=x+11$

Since $\triangle{STU}$ is equilateral, all three sides are equal. Therefore:

$\left[\begin{array}{l}y=2x-1\\y=5x-37\\y=x+11\end{array}\right]$

Substituting y = x + 11:

$\left[\begin{array}{l}x+11=2x-1\\x+11=5x-37\end{array}\right]$

Solving for x:

$x+11=2x-1\\11=x-1\\12=x$

Substituting x = 12:

$y=x+11\\y=12+11\\y=23$

Thus, <em>x</em> = 12 and the length of each side is 23.
