1 answer:

To solve this problem, we simply divide the new quantity by the old quantity.

57 ÷ 60 = 0.95

Now convert this decimal into a percent.
We convert decimals into percents by moving the decimal point two places to the right and make it into a % sign.

0.95 = 95%

And finally, subtract 95% from 100%.

100% - 95% = 5%

So, the decrease was 5%.

QUESTION 1

The given logarithmic expression is

$\log_4(\frac{1}{16})$

We rewrite $\frac{1}{16}$ in the index form to base 4.

This implies that;

$\log_4(\frac{1}{16})=\log_4(4^{-2})$

We now apply the power rule: $\log_a(m^n)=n\log_a(m^n)$ .

$\log_4(\frac{1}{16})=-2\log_4(4)$

Recall that logarithm of the base is 1.

$\log_4(\frac{1}{16})=-2(1)$

$\log_4(\frac{1}{16})=-2$

QUESTION 2

The given logarithm is;

$\log_2(\sqrt[5]{32})$

$\log_2(\sqrt[5]{2^5})$

This is the same as;

$\log_2(2^{5\times \frac{1}{5}})$

$\log_2(2^{1})$

$\log_2(2)=1$

4. 7 - (-2y) + y - 9....y = 6
7 - (-2(6) + 6 - 9 = 7 + 12 + 6 - 9 = 16

7. -x + 8 + 7x - (-1).....x = -10
-(-10) + 8 + 7(-10) + 1 = 10 + 8 - 70 + 1 = -51

Lines b and care parallel.

Vinil7 [7]

Answer:

<h3>Option 2 </h3>

angle 2 = 7x + 1 ( vertically opposite angles)

7x + 1 + 18x + 4 = 180° ( forming linear pair).

7x + 18x + 4 +1 = 180°

25x + 5 = 180°

25x = 180 - 5

25x = 175

x = 7°

angle 2 = 7(7)+ 1

= 50°

Solve. 15 − 6(x + 1) = 12<br> Help nowwwww

Gekata [30.6K]

Answer:

Your answer would be 2

Step-by-step explanation:

15 - 6(x+1) =12

15- 6*x +6*1 = 12

15 - 6x + 6 = 12

15 - 6 + 6x = 12

9 + 6x = 12

9 - 9 + 6x = 12 - 9

6x = 3

x = 2
