1. Is 2/12 = 5/28 a true proportion?

Mathematics
1 answer:
Travka [436]2 years ago
6 0

Answer:

\dfrac{2}{12}=\dfrac{5}{28}

Cross multiply:

⇒ 2 x 28 = 5 x 12

⇒ 56 = 60

Is this proportion true?

No, because the cross products are not equal.

The proportion is not true, because 2/12 and 5/28 are not equivalent ratios.

Need help on 39 please

That is actually easier thatn it looks

here is  a tip
write that thing apart since they are all multiplication like this:
V=(1/3)pir^2  h
now just divide the whole equaiton by ((1/3)pir^2)
or if you don't like dividiing by fracitons, times both sides by 3/1 to clear fraction to get
3V=pir^2h
divide both sides by pir^2
(3v)/(pir^2)=h

Fill in the missing values to make the equations true.(a) log, 7 + log2 5 = log2음Х8(b) log, 8 - log, I = log,7(c) log, 4 = 2log,
Zielflug [23.3K]

(a).

Simplify the expression to obtain the value at missing place.

\begin{gathered} \log _27+\log _25=\log _2(7\cdot5) \\ =\log _235 \end{gathered}

Blank space: 35

(B).

Simplify the expression to obtain the value of missing place.

\log _9(\frac{8}{7})=\log _98-\log _97

Blank space : 7

(C)

Simplify the expression to obtain the value at missing place.

\begin{gathered} \log _74=\log _7(2)^2 \\ =2\log _72 \end{gathered}

Blank space: 2

Rewrite the following equation in standard form.<br><br> y=1/10x− 2/9
rjkz [21]

The answer is  9x - 90y = 20.

Explanation:

y = 1/10 x - 2/9

First eliminate the fractions by multiplying through by the LCM which is 90:-

90y = 9x - 20

Standard form is ax + by = c, so rearranging we get:

0 = 9x - 90y - 20

9x - 90y = 20 .
