Explanation:

To find what is 30% of 150, we will need to write an equation. We will convert 30% into fraction form, then multiply 150 with the fraction. Once multiplied, we will get our result.

Solution:

30% = 30/100
=> 30/100 x 150
=> (30/50 × 2) × 3 × 50
=> 15/50 × 3 × 50
=> 15 × 3
=> 45

Final Answer:

30% of 150 is 45.

Answer:

30% of 150 is 45

Step-by-step explanation:

30% = .3 x 100

So take 30% out of its percentage form

then multiply .3 and 150

150 x 0.3 = 45

Henceforth, 30% of 150 is 45

What is the pattern in the values as the exponents increase? Powers of 2 Value 2 Superscript negative 5 StartFraction 1 Over 32

Tatiana [17]

Answer:

(D)Multiply the previous value by 2

Step-by-step explanation:

$\left|\begin{array}{c|c}$Powers of 2&Value\\2^{-5}&\frac{1}{32}\\\\2^{-4}&\frac{1}{16}\\\\2^{-3}&\frac{1}{8}\\\\2^{-2}&\frac{1}{4}\\\\ 2^{-1}&\frac{1}{2}\\\\2^{0}&1\end{array}\right|$

From the given table, we observe that the negative power of 2 reduces by 1 at each step.

$2^{-5}X2=2^{-4}\\2^{-4}X2=2^{-3}\\2^{-3}X2=2^{-2}$

Therefore, as the exponents increase, we multiply the previous value by 2 to obtain the next value.

The correct option is D.

Sophie practices the piano 105 minutes in 1 week. If t represents the total time she practices for any number of days, d, write

Alex Ar [27]

Answer:

Step-by-step explanation:

You must first know that 1 week = 7days

If Sophie practices the piano 105 minutes in 1 week, this can be expressed as;

105 minutes = 7days

to calculate the total time t that she practices for any number of days, d, we will say;

t minutes = d days.

Solving both expression;

105 minutes = 7days

t minutes = d days.

Cross multiply;

7 * t = 105 * d

7t = 105d

Divide both sides by 7;

7t/7 = 105d/7

t = 15d

Hence a proportional equation for t in terms of d that matches the context is expressed as t = 15d

24-4x=2x<br> show your work, will mark brainliest

vladimir2022 [97]

Answer:

x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

24−4x=2x

24+−4x=2x

−4x+24=2x

Step 2: Subtract 2x from both sides.

−4x+24−2x=2x−2x

−6x+24=0

Step 3: Subtract 24 from both sides.

−6x+24−24=0−24

−6x=−24

Step 4: Divide both sides by -6.

−6x /−6 = −24 /−6
