15 + 48 ÷ (–2) raised to power 4 *
Greetings from Brasil...
First we will solve the power:
(- 2)⁴ = (- 2)·(- 2)·(- 2)·(- 2) = + 16
rewriting our expression
15 + 48 ÷ (–2)⁴
15 + 48 ÷ 16
(the division / multiplication has priority over the addition / subtraction, so let's do the division first 48 ÷ 16 = 3)
15 + 3

I really stuck on this question can someone help me out? What rational number, when multiplied by an irrational number, has a product that is a rational number? a. 1/2 b. 1 c. 1/10 d. 0
Answer:
d. 0
Step-by-step explanation:
Given that:
A rational number is multiplied by a irrational number.
And the result is a rational number.
To find:
Such rational number wil be:
a. [tex]\frac{1}2[/tex]
b. 1
c. [tex]\frac{1}{10 }[/tex]
d. 0
Solution:
Let us consider the given options one by one.
Let the irrational number be = [tex]\pi[/tex]
Checking option a.
Multiply [tex]\pi[/tex] and [tex]\frac{1}2[/tex].
Result is: [tex]\frac{\pi}2[/tex] which is again irrational.
So, a. is not correct.
Checking option b.
Multiply [tex]\pi[/tex] and 1.
Result is: [tex]\pi[/tex] which is again irrational.
So, b. is not correct.
Checking option a.
Multiply [tex]\pi[/tex] and [tex]\frac{1}{10}[/tex].
Result is: [tex]\frac{\pi}{10}[/tex] which is again irrational.
So, c. is not correct.
Checking option d.
Multiply [tex]\pi[/tex] and 0.
Result is: 0 which is rational.
So, d. 0 is the correct answer.
please help :) Evaluate the expression: 75+125÷25×5 A.1.6 B. 40 C. 100 D. 76
Answer:
C = 100
Step-by-step explanation:
PEMDAS
multiplication and division first from left to right so
125/25 = 5
5x5 = 25
25 + 75 = 100
Answer:
C. 100
Step-by-step explanation:
To complete this question you must use systems of equations.
First you must complete multiplication or division depending on which comes first in the left to right sequence. In this case it is 125/25 which equals 5. This now makes the equation 75+5 x 5
Next, you complete any other division or multiplication Which in this case is, 5x5. The answer to this is 25, making the new equation, 75+25 which when added together equals 100!
And that is how you use systems of equations. Hope it helps ;)

Step-by-step explanation:
First, write out the equation as you have been given in the problem:
[tex]5(3c-[d-2(c+d)])\\[/tex]
Next, distribute the -2 to the set of parenthesis containing "c+d" and combine any like terms that you can:
[tex]5(3c-[d-2c-2d])\\5(3c-[-2c-d])[/tex]
Then, distribute the "-"to the "-2c-d" in the brackets and combine and like terms that you can:
[tex]5(3c+2c+d)\\5(5c+d)[/tex]
Finally, distribute the coefficient 5 to the terms inside the parenthesis:
[tex]25c+5d[/tex]
Therefore, 25c+5d is you simplified answer to the problem.

Lawrence, an attorney, charges an initial fee of $100 plus $75 per hour for a consultation. He typically charges
clients either less than $250 or more than $700. Which inequality represents x, the typical number of hours
worked?
75x + 100 < 250 or 75x + 100 > 700
100x + 75 < 250 or 100x + 75 > 700
250 < 75x + 100 < 700
250 < 100x + 75 < 700
Answer:
75x + 100 < 250 or75x + 100 > 700Step-by-step explanation:
This problem basically tests our understanding of representing word problems using inequalities and equations.
In the first instance, Lawrence can charge his client an amount that is less than $250, hence all terms to the right should not be greater $250 when executed.
Also, the second expression says that he can also charge more than $700 when hence all terms in the right-hand side should be greater than $700 when executed

Please solve 4x = 24
Answer:
x is equal to six
Step-by-step explanation:
4 × 6 = 24
Answer: There is only one step to this equation. We will use inverse operations to isolate the x by dividing 4 on both sides. (4 is being multiplied by x, and the opposite of multiplication is division.)
4x/4 = x
24/4 = 6
The equation now looks like:
x = 6
x is equal to 6, so this is your answer.
1. Are there more inches in a mile or second in a day?
Answer:
Step-by-step explanation:
60 x 60 = 3600
3600 x 24
5280 x 12
I know for steps 2 and 3 to be equal, 3600 would have to be half of 5280 because 24 is twice 12, and it’s not. And because 3600 is more than half of 5280, I know that 3600 times 24 is more than 5280 times 12. My answer, therefore, is there are more seconds in a day.

Answer:
The answer is
[tex]x = \frac{ {e}^{ \frac{3}{ ln(2) } } }{4} [/tex]Step-by-step explanation:
[tex] ln(2) \times ln(4x) = 3[/tex]Divide both sides of the equation by ln 2
That's
[tex] \frac{ ln(2) ln(4x) }{ ln(2) } = \frac{3}{ ln(2) } [/tex]We have
[tex] ln(4x) = \frac{3}{ ln(2) } [/tex]Covert the logarithm into exponential form using the property
[tex] ln(x) = b\: \: is \: \: \: the \: \: \: same \: \: \: as \: \: \: \:
x = {e}^{b} [/tex]Are all the same
So
[tex] ln(4x) = \frac{3}{ ln(2) } [/tex]is the same as
[tex]4x = {e}^{ \frac{3}{ ln(2) } } [/tex]Divide both sides by 4
We have the final answer as
[tex]x = \frac{ {e}^{ \frac{3}{ ln(2) } } }{4} [/tex]Hope this helps you
Solve for h.
-12h + 4 = 0
Answer:
[tex]h=1/3[/tex]
Step-by-step explanation:
So we have the equation:
[tex]-12h+4=0[/tex]
Subtract 4 from both sides:
[tex](-12h+4)-4=(0)-4\\-12h=-4[/tex]
Divide both sides by -12:
[tex](-12h)/-12=(-4)/-12\\h=-4/-12[/tex]
Simplify and reduce:
[tex]h=1/3[/tex]
Answer:
h =1/3
Step-by-step explanation:
[tex]-12h + 4 = 0\\\\\mathrm{Subtract\:}4\mathrm{\:from\:both\:sides}\\-12h+4-4=0-4\\\\\mathrm{Simplify}\\-12h=-4\\\\\mathrm{Divide\:both\:sides\:by\:}-12\\\frac{-12h}{-12}=\frac{-4}{-12}\\\\Simplify\\h=\frac{1}{3}[/tex]

Solve for x in the simplest form 11=1/2(x+8)
Answer:
[tex] \boxed{\sf x = 14} [/tex]
Step-by-step explanation:
Solve for x:
[tex] \sf \implies 11 = \frac{1}{2} (x + 8)[/tex]
[tex] \sf 11 = \frac{1}{2} (x + 8) \: is \: equivalent \: to \: \frac{1}{2} (x + 8) = 11 : [/tex]
[tex] \sf \implies \frac{1}{2} (x + 8) = 11[/tex]
[tex] \sf Multiply \: both \: sides \: of \: \frac{1}{2} (x + 8) = 11 \: by \: 2 : [/tex]
[tex] \sf \implies \frac{1}{ \cancel{2}} (x + 8) \times \cancel{2 }= 11 \times 2[/tex]
[tex] \sf \implies 1(x + 8) = 11 \times 2[/tex]
11 × 2 = 22:
[tex] \sf \implies x + 8 = 22[/tex]
Subtract 8 from both sides:
[tex] \sf \implies x + (8 - 8) = 22 - 8[/tex]
8 - 8 = 0:
[tex] \sf \implies x = 22 - 8[/tex]
22 - 8 = 14:
[tex] \sf \implies x = 14[/tex]
The value of x is 4, for the equation 11 = 1/2 (x + 8).
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equation is,
11 = 1/2 (x + 8)
Simplify the equation by multiplying 2 in both the sides,
11 × 2 =2 × 1/2 × (x + 8)
22 = x + 8
Subtract 8 from both the sides,
22 - 8 = x + 8 - 8
14 = x
or x = 14
The required value of x for the given equation is 14.

A drive has a maximum speed of 10000 revolutions per minute. If a disc has a diameter of 12 cm what is the linear speed, in km/h, of a point 4cm from the center if the disc is spinning at a rate of 7000 revolutions per minute?
Answer:
10.8 km/hr
Step-by-step explanation:
Given that
radius of the diameter is 4 cm
Converting 4 cm to km, we have
4/100000 = 0.00004 km or 4*10^-5 km
Angular speed is given as
v = 2πr/T
Where T is, 1/n,and n is the number of revolutions
v = (2 * 3.142 * 0.00004) / (1/7000)
v = 0.00126 / 0.007
v = 0.18 km/min
This is in km/min, now we convert to km/hr as requested.
0.18 * 60 = 10.8 km/hr
