The perimeter of a collage basketball court is 96 meters and the length is 14 meters more than the width. What are the dimensions? HELP MEEEEE

Answers

Mark Brainliest please

Perimeter of a rectangle,

Pr = 2L+ 2W

L = (W + 14)

Pr = 2(W+14) + 2W

Pr= 2W + 28 +2W

Pr =96 = 4W + 28

Pr = (96 — 28) = 4W

Pr = 68 = 4W

W = 68/4 = 17m, L= 17+14 = 31m

Check:

17m+17m+31m+31m= 96m

Answer:

width = 17 m ; length = 31 m

Step-by-step explanation:

w = width

l = length

perimeter of a rectangle = (length + width) * 2

l = 14 + w

(14 + w + w) * 2 = 96

(14 + 2w) * 2 = 96

28 + 4w = 96

4w = 68

w = 17 m

l = 14 + 17 = 31 m

Which system of linear inequalities has the point (3, -2) in its solution set?

Answers

Answer:

None of the given system of linear inequalities

Step-by-step explanation:

Given

[tex](x,y) =(3,-2)[/tex]

Required

The line inequalities with the above solution

The first set of linear inequalities, we have:

[tex]y < -3[/tex]

[tex]y \ge \frac{2}{3}x - 4[/tex]

[tex]y < -3[/tex] implies that the values of y is -4,-5.....

While [tex](x,y) =(3,-2)[/tex] implies that y = -2

Hence, the first set is wrong

The second set of linear inequalities, we have:

[tex]y > - 2[/tex]

[tex]y \ge \frac{2}{3}x - 4[/tex]

[tex]y > - 2[/tex] implies that the values of y is -1,0.....

While [tex](x,y) =(3,-2)[/tex] implies that y = -2

Hence, the second set is wrong

The system of linear inequalities having the point (3, -2) in its solution set is y > -3; y ≥ 2/3x - 4.

What are systems of linear inequalities?

A system of linear inequalities is known to be a composition of  linear inequalities that can be found in the same variables.

The graph that is showing  y > -3; y ≥ 2/3x - 4

-2 > -3  is true

y ≥ 2/3x - 4

-2 ≥ -2  is true

Therefore,  y > -3; y ≥ 2/3x - 4 has the point (3, -2) in its solution set.

Mr. Mason’s class is going on a field trip. There are 27 students. There will be 1 adult for every 9 students. Mr. Mason wants to know how many adults (n) are needed for the field trip. Which of the following equations should he use?
A. 9n + 27
B. 27 – 9n
C. 9n = 27 - 1
D. 9n = 27

Answers

Answer:

D. 9n = 27

Step-by-step explanation:

If we need one adult for every 9 students, we can represent that as 9n:

if n is the number of adults.

Because we have 27 students, the equation 9n = 27 works.

A better way of formatting the equation is:

n = 27/9

Because it directly shows what the number of adults is, but with some reformatting, it is clearly the same equation.

Find the time required for an investment to double in value if invested in an account paying 3% compounded quarterly.

Answers

Answer: [tex]6.12\ \text{years}[/tex]

Step-by-step explanation:

Given

Rate of interest is [tex]r=3\%[/tex] compounded quarterly

So, annually it is [tex]r=12\%[/tex]

Suppose [tex]P[/tex] is the Principal and A is the amount after certain time period.

Amount in Compound interest is given by

[tex]\Rightarrow A=P[1+r\%]^t[/tex]

for given conditions

[tex]\Rightarrow 2P=P[1+0.12]^t\\\Rightarrow 2=(1.12)^t\\\\\Rightarrow t=\dfrac{\ln (2)}{\ln (1.12)}\\\\\Rightarrow t=6.116\approx 6.12\ \text{years}[/tex]

It take [tex]6.12\ \text{years}[/tex] to double the invested amount.

Suppose 180 randomly selected people are surveyed to determine whether or not they plan on voting to reelect the current president. Of the 180 surveyed, 36 reported they will not vote to reelect the current president. Identify the values needed to calculate a confidence interval for the proportion that will not vote to reelect the current president at the 99% confidence level. Then find the confidence interval.

Answers

Answer:

(0.123 ; 0.277)

Step-by-step explanation:

Given :

Sample size, n = 180

x = 36

Proportion, p = x / n = 36/180 = 0.2

Confidence interval for sample proportion :

Confidence interval :

p ± Zcritical * √p(1 - p) / n

Zcritical at 99% = 2.576

0.2 ± 2.576 * √0.2(1 - 0.2) / 180

Find the value of a for which there is no term independent of x in the ezlxpansion of
[tex](1 + ax {}^{2} )( \frac{2}{x} - 3x) {}^{6} [/tex]

Answers

"no terms independent of x" basically means there is no constant term, or the coefficient of x ⁰ is zero.

Recall the binomial theorem:

[tex]\displaystyle (a+b)^n=\sum_{k=0}^n\binom nk a^{n-k}b^k[/tex]

So we have

[tex]\displaystyle \left(1+ax^2\right)\left(\frac2x-3x\right)^6 = \left(1+ax^2\right) \sum_{k=0}^6 \binom 6k \left(\frac2x\right)^{6-k}(-3x)^k[/tex]

[tex]\displaystyle \left(1+ax^2\right)\left(\frac2x-3x\right)^6 = \left(1+ax^2\right) \sum_{k=0}^6 2^{6-k}(-3)^k\binom 6k x^{2k-6}[/tex]

[tex]\displaystyle \left(1+ax^2\right)\left(\frac2x-3x\right)^6 = \sum_{k=0}^6 2^{6-k}(-3)^k\binom 6k x^{2k-6}+a\sum_{k=0}^6 2^{6-k}(-3)^k\binom 6k x^{2k-4}[/tex]

The first sum contributes a x ⁰ term for 2k - 6 = 0, or k = 3, while the second sum contributes a x ⁰ term for 2k - 4 = 0, or k = 2. The coefficient of the sum of these terms must be zero:

[tex]2^{6-3}(-3)^3\dbinom 63 + a\times2^{6-2}(-3)^2\dbinom 62 = 0[/tex]

which reduces to

2160a - 4320 = 0

2160a = 4320

A rectangular room is 6 meters longer than it is wide, and its perimeter is 28
meters. Find the dimension of the room.

Answers

Answer: width = 4 and length = 10

Step-by-step explanation:

Width = w and length = w + 6

2(w) + 2 (w + 6) = 28

2w + 2w + 12 = 28

4w = 28 - 12

W = 16/4

W = 4 (width)

Length = w + 6

4 + 6 = 10

In order to estimate the average time spent per student on the computer terminals at a local university, data were collected for a sample of 81 business students over a one-week period. Assume the population standard deviation is 1.8 hours. If the sample mean is 9 hours, then the 95% confidence interval is

Answers

Answer:

(8.608, 9.392)

Step-by-step explanation:

We have the following information

Population standard deviation = 1.8

Sample mean = 9 hours

Sample n = 81

C I = 95%

So level of significance

Alpha = 1-0.95

= 0.05

Z critical at 0.05/2

Z(0.025) = 1.96

The 95% c.i =

9+-(1.96)(1.8/√81)

9+-(1.96)(0.2)

(9-0.392)(9+0.392)

(8.608, 9.392)

This is the confidence interval at 95%.
