Joe drives 20 mi-in 1/2 h. how Long Will it take him to derive 50 mi?

Answers

An hour and 15 minutes. Since Joe is driving 20 miles per 1/2 hour that means he is driving 40 miles every hour. We still have 10 miles left and since 20 divided by 2 is ten you would simply cut the time it takes him to drive 20 miles in half making 15 minutes. Then you add the time it takes to drive 40 miles and 10 miles and that's how you get an hour and 15 minutes. Hope this made sense!

a survey in which 400 people were asked to identify the TV channel on which they preferred to watch the evening news.

How many more people preferred WWCN with 41% than WANR with 22%?
A. 164
B. 76
C. 236
D. 68

Answers

So, Steve's time in a ratio to Paul's time:

$(Steven's time)/(Pauls's time) = (10)/(12) = (5)/(6) .$ So Steven's time is $(5)/(6)$ times shorter, that is
"Steven is $(5)/(6)$ times faster than Paul (I find the phrasing "as fast as" problematic though)

In the second question 41% of 400, which is 4*41=164 people chose WWCN and 22% chose WANR, that is 22%*400=4*22=88.

And the difference is 76 people! ( 164-88=76)B)

Answer:

Q-1 The correct option is A) Steve is 5∕6 as fast as Paul

Q-2 The correct option is 76.

Step-by-step explanation:

Consider the provided information.

Q-1

Steve can complete the 100m dash in 10 seconds while Paul can run it in 12 seconds.

Since, the distance for both are same,

$\frac{\text{Steve's time}}{\text{Paul's time}}=(10)/(12)=(5)/(6)\n\text{Steve's time}=(5)/(6)\text{ of Paul's time}}$

Hence, Steve's time is 5⁄6 of the time taken by Paul.

Therefore, the correct option is A) Steve is 5∕6 as fast as Paul

Q-2 a survey in which 400 people were asked to identify the TV channel on which they preferred to watch the evening news.

WWCN got 41% and WANR got 22%

For WWCN

41% of 400 is: $(41)/(100) * 400=164$

That means 164 people preferred WWCN.

For WANR

22% of 400 is: $(22)/(100) * 400=88$

That means 88 people preferred WANR.

We need to find how many more people preferred WWCN

For this subtract both the values: 164-88=76

Thus, 76 more people preferred WWCN

Hence, the correct option is 76.

Which of the following numbers has a prime factorization of 3 x 3 x 3?9

27

Answers

Not completely sure on this one, but the answer I would go with is C (21) because if you factor it out it is 3x7. Both of these numbers are prime. The only thing that is confusing me in your question is the 3x3x3. if you are just asking what 3x3x3 is, then it is 9... so A.

Which of the following numbers has a prime factorization of 3 x 3 x 3?Answer: 27

Answer and maybe an explanation.Thanks in advance.

Answers

inverses

solve for x
replace x with f inverse
replace y with x

so
first minus 2 both sides
y-2=√(2x-3)
square both sides
y^2-4y+4=2x-3
add 3 to both sides
y^2-4y+7=2x
divide both sides y 2
(y^2-4y+7)/2=x

x turns to f inverse and y turns to x

f(x)⁻¹= $(x^(2)-4x+7)/(2)$

looks like they didn't want to expand the binomial

y= $\frac{(x-2)^(2)}+3}{2}$

What is 21x^6y^5 divided by 14x^y^9 will make brainliest lot of points on the line too

Answers

The simplified expression is: (3/2) x⁵ * (1/y⁴), or (3x⁵) /(2y⁴).

What is indices?

Indices, in mathematics, refer to the small numbers or symbols (exponents) used to indicate the power or exponent to which a number is raised, often in the context of exponents or powers.

To divide the expression (21x⁶y⁵) by (14x¹y⁹), simplify by subtracting the exponents of like terms:

(21x⁶y⁵) / (14x¹y⁹) = (21/14) * (x⁶⁻¹ * (y⁵⁻⁹))

Now simplify each part:

121/14) simplifies to (3/2)

x⁶⁻¹ simplifies to x⁵

3. y⁵⁻⁹ simplifies to y⁻⁴

So, the simplified expression is

(3/2) x⁵ * (1/y⁴), or (3x⁵) / (2y⁴).
