5 / 3 x + 1 / 3x equals 13 + 1 / 3 x + 8 / 3 x

NNADVOKAT [17]

Answer: x = - 12/9 ( the equation is negative)

Step-by-step explanation:

\frac{5}{3}x+\frac{1}{3}=13+\frac{1}{3}x+\frac{8}{3}x

\frac{5}{3}x=3x+\frac{38}{3}

\frac{5}{3}x-3x=3x+\frac{38}{3}-3x

-\frac{4}{3}x=\frac{38}{3}

3\left(-\frac{4}{3}x\right)=\frac{38\cdot \:3}{3}

-4x=38

\frac{-4x}{-4}=\frac{38}{-4}

x=-\frac{19}{2}

Rectangle ABCD is similar to rectangle RSTU .

Alenkasestr [34]

Answer:

The scale factor of a dilation from ABCD to RSTU is $\frac{1}{2}$

Step-by-step explanation:

We know that the rectangle ABCD is similar to rectangle RSTU.

Given that in rectangle ABCD the longest sides are DC and AB and in the rectangle RSTU the longest sides are UT and RS ⇒ The scale factor of a dilation will transform the sides DC and AB into UT and RS

Working with the lengths of the sides :

DC.(Scale factor) = UT

AB.(Scale factor) = RS

Replacing with the values of the lengths (Scale factor : SF) :

$DC.SF=UT\\(90ft).(SF)=45ft\\SF=\frac{45ft}{90ft} \\SF=\frac{1}{2}$

$AB.SF=RS\\(90ft).(SF)=45ft\\SF=\frac{45ft}{90ft} \\SF=\frac{1}{2}$

Notice that the scale factor is dimensionless.

We can verify this result with the sides AD and BC :

$AD.SF=UR\\50ft.(\frac{1}{2})=25ft\\ 25ft=25ft$

$BC.SF=TS\\50ft.(\frac{1}{2})=25ft\\ 25ft=25ft$

The scale factor (SF) is $\frac{1}{2}$

In a batch of 280 water purifiers, 12 were found to be defective. What is the probability that a water purifier chosen at random

aleksley [76]

This is experimental probability.

If 12 were found to be defective out of 280 the experimental probability of a purifier being defective is:

12/280 which is:

4.3% (to nearest tenth of a percent)
