#SPJ2

Kat's study score rate is 5 points per hour. To achieve a score of 90, given her current study rate, she should spend 18 hours studying for the exam.

Since the average score Kat gets on her exams is proportional to the amount of time she studies, her score is a measure of her rate of study. This 'rate' can be computed as the score divided by the time she studies. She got a 75 after studying for 15 hours, so her rate is 75/15 = 5 - this means she scores 5 points per hour of studying.

To figure out how many hours she needs to study to score a 90 in the next exam, divide the score she needs (90) by her rate (5). So, 90/5 = 18. Thus, Kat needs to study for 18 hours to achieve a score of 90 on her next exam.

Final answer:

The number of permutations for 4 P 4 is calculated as 4! (four-factorial), which is 4 x 3 x 2 x 1, resulting in 24 different permutations.

Explanation:

The question asks for the number of permutations for 4 P 4, which is the number of ways to arrange 4 unique items. When dealing with permutations, if we want to select r items from a set of n items, the formula for permutations is given by nPr = n! / (n-r)!. In this case, both n and r are equal to 4, so we would calculate 4P4 as 4! / (4-4)! which simplifies to 4! / 0!. Because 0! is defined to be equal to 1, the calculation becomes 4! Therefore, 4 P 4 equals 24.

Answer:

Jon lost a total of 3 kilograms in these 3 months.

Step-by-step explanation:

Weight that Jon gained in December = 2.2 kilograms

Weight that Jon lost in January = 1.5 kilograms

Weight that Jon lost in February = 3.7 kilograms

Overall Change in his weight = Total Weight he gained - Total weight he Lost

Total weight he gained is 2.2 kilograms as he only gained weight in December. Total weight he lost will be sum of weights he lost in January and February.

So, total weight Jon lost = 1.5 + 3.7 = 5.2 kilograms

Thus,

Total change in Jon's Weight = 2.2 - 5.2 = -3.0 kilograms

This shows that Jon lost a total of 3 kilograms in these 3 months.

Conclusion:

The statement that best describe the total change in his weight is: Jon lost a total of 3 kilograms in these 3 months

Hello!

The answer should be 0.34%

Explanation: First you had to start by representing by the percent with a variable by the x%. Then you can also used x% to create an algebraic expression. It gave us 29%*x=3. Next solve for x by dividing by 29 from both sides. It gave us 29x÷29=3÷29, or x≈0.1034. Then convert 0.1034 into a percent by multiplying by the decimal by 100%. And it gave us x≈0.1034*100%, and the answer is x≈10.34% is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. Have a great day! -Charlie

The percentage of 29 that is equal to 3 is 10.34% calculated by making percentage the subject of the equation.

To find the percentage of one number in relation to another, you can use the following formula:

(Percentage / 100) * Number = Part

In this case, we want to find what percent 3 is of 29.

Let's substitute the values into the formula:

(Percentage / 100) * 29 = 3

To isolate the percentage, we divide both sides of the equation by 29:

(Percentage / 100) = 3 / 29

To find the percentage, we multiply both sides by 100:

Percentage = (3 / 29) * 100

Calculating this expression:

Percentage = 10.34

Therefore, 3 is approximately 10.34% of 29.

Answer:

6 1/4

Step-by-step explanation:

To factorize the expression completely, we use the difference of squares formula and simplify the expression to get 6x.

The given expression is (2x+1)^2 -(x-1)^2. To factorize it completely, we can use the difference of squares formula, which states that (a^2 - b^2) = (a + b)(a - b). Applying this formula, we have:

(2x+1)^2 -(x-1)^2 = [(2x+1) + (x-1)][(2x+1) - (x-1)]

Simplifying further, we get:

(2x+1+x-1)(2x+1-x+1) = (3x)(2) = 6x.

Volume increasing rate = [tex]62831.85 mm^3/s[/tex]

Explanation:

We rate of change of radius of sphere, [tex]\frac{dr}{dt} =2mm/s[/tex]

Diameter of sphere = 100 mm

Radius of sphere = 50 mm

Volume of sphere, V = [tex]\frac{4}{3} \pi r^3[/tex]

Rate of change of volume = [tex]\frac{dV}{dt}[/tex]

[tex]\frac{dV}{dt}=\frac{d}{dt} (\frac{4}{3} \pi r^3)=\frac{4}{3} \pi\frac{d}{dt}(r^3)=\frac{4}{3} \pi*3r^2*\frac{dr}{dt}[/tex]

Substituting known values

     [tex]\frac{dV}{dt}= \frac{4}{3}* \pi*3*50^2*2=62831.85 mm^3/s[/tex]

Volume increasing rate = [tex]62831.85 mm^3/s[/tex]

Step-by-step explanation:

distance = d = sqrt [ (a-c)^2 + (b-d)^2 ]

Answer:

[tex]d=\sqrt{(c-a)^2+(d-b)^2}[/tex]

Step-by-step explanation:

We are given two points (a, b) and (c, d)

We need to find the distance between two points.

It is coordinate of two points. Using coordinate formula of distance.

[tex]d=\sqtt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where,

[tex]x_2\rightarrow c[/tex]

[tex]x_1\rightarrow a[/tex]

[tex]y_2\rightarrow d[/tex]

[tex]y_1\rightarrow b[/tex]

Substitute into formula

Distance between two points is

[tex]d=\sqrt{(c-a)^2+(d-b)^2}[/tex]

Hence, The formula of distance between two points  (a, b) and (c, d) is [tex]d=\sqrt{(c-a)^2+(d-b)^2}[/tex]

Answer:

F = (9/5) (K - 273) + 32

Step-by-step explanation:

The problems asks to use the formula C=59(F−32), but check that this is not correct, it should be:

[tex]C = \frac{5}{9} (F - 32)[/tex]

We also know that temperature in degrees Kelvin K is 273 more than in degrees Celsius C, so we can write this as:

K = C + 273

The question asks to write a formula for the temperature in degrees Fahrenheit F in terms of the temperature in degrees Kelvin K.

So first lets isolate F in the first formula

[tex]C = \frac{5}{9} (F - 32)[/tex]

[tex]C = \frac{5}{9} (F - 32)\\C * \frac{9}{5} = \frac{5}{9}* \frac{9}{5}(F - 32)\\C * \frac{9}{5} = F - 32\\C * \frac{9}{5} +32 = F - 32 +32\\F = \frac{9}{5} C +32[/tex]

Now to make the formula in terms of K, lets first write C in terms of K:

K = C + 273

C = K -273

And now we can replace C in the F formula to write it in terms of K:

F = (9/5) (K - 273) + 32

It would be a closed circle or "dot" since it is a less than or equal to sign.

To solve this problem, one would need to use the binomial probability formula, substituting different values of 'x' into the formula depending on the requirement of the question. To calculate probabilities for specific numbers of people saying cashews are their favorite, substitute those numbers into the formula and solve, adding appropriate probabilities together for situations with ranges of people.

The subject of this question is probability. We can use the binomial probability formula, which is P(X=x) = C(n, x) * (p^x) * ((1-p)^(n-x)), where 'p' is the probability of success, 'n' is the number of trials, and 'x' is the number of successful outcomes.

(a) For exactly 3 people loving cashews, substitute x=3, p=0.32 (32%), and n=12 into the formula to calculate the probability.
(b) For at least 4 people loving cashews, calculate the probability for x=4, x=5,....x=12 and add these probabilities together as this is an 'or' condition.
(c) For 2 or fewer people loving cashews, calculate the probability for x=0, x=1, x=2 and add them, because it says 'at most two' which includes 0 to 2 people.

the answer would be 374.00

the original value before any increase or decrease is 340.00

so...

340.00 X 1.10 = 374.00

Answer:

New Wage after 10% increase =£374

Step-by-step explanation:

Let us assume  Carol's initial weekly wage be £ x

Now there is 10% decrease in weekly wage

10 %  of weekly wage = 10 % of x

                                    =  [tex]\frac{10x}{100} = 0.1x[/tex]

New wage after 10% decrease =  initial weekly wage - 10% of x

                                                   =  [tex]x- 0.1x = 0.9x[/tex]

It is given that new weekly wage is £ 306

so we equate £306 and 0.9x , so we have

[tex]0.9x=306[/tex]

[tex]x=\frac{306}{0.9}[/tex] ( divide both sides by 0.9)

[tex]x= 340[/tex]

So we got

Initial weekly wages = £ 340

Now Let us find weekly wage when there is 10% increase,

10% of initial weekly wage = [tex]10% of 340[/tex]

                                            =[tex]\frac{10}{100}[/tex]×[tex]340[/tex]

                                            = [tex] 34[/tex]

New Wage after 10% increase = [tex]340+34[/tex]

                                                  =£ 374

[tex]2^x\cdot 3^x=200\\\\(2\cdot3)^x =200\\\\6^x=200\\\\x=\log_6200\\\\x=\dfrac{\ln 200}{\ln 6}\\\\x\approx2.96[/tex]
