100,000,000 sheep are in a field the farmer says there are 36 acres for each sheep how many acres are there in the field​

Answer:

85°

Step-by-step explanation:

x+32°+63°=180°(being sum of interior angle of triangle)

x=180°-95°

:. x=85°

Complete question :

Online photos: A poll surveyed 1765 internet users and found that 865 of them had posted a photo or video online. Can you conclude that less than half of internet users have posted photos or videos online? Use the α 0.01 level of significance and the P-value method with the TI-84 calculator.

1. State the appropriate null and alternate hypotheses.

2. Compute the P-value.

Answer:

H0 : p = 0.5

H1 : p < 0.5

P value = 0.200454

Step-by-step explanation:

Given that :

Claim : Less than half internet users have posted photos or videos online.

Sample Proportion (p) = 865 / 1765 = 0.4900

The null hypothesis : H0 : p = 0.5 (that is half of internet users have posted photos online.

The alternative hypothesis : H1 : p < 0.5 (that is less than half of internet users have posted photo or video ;

P = 0.5

q = 1 - 0.5 = 0.5

The test statistic :

Z = p - p0 / sqrt(p0 * (q/n))

Z = (0.49 - 0.5) / sqrt(0.5 * (0.5/1765))

Z = - 0.01 / sqrt(0.5 *0.0002832)

Z = - 0.01 / sqrt(0.0001416)

Z = - 0.01 / 0.0119013

Z = - 0.8402443

The corresponding p value from the z statistic score at α = 0.01

= 0.200454

Answer:

x = - 1 ± i[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Given

3s² + 8s = 2s - 9 ( subtract 2s - 9 from both sides )

3s² + 6s + 9 = 0

To complete the square

The coefficient of the s² term must be 1, so factor out 3 from 3s² + 6s

3(s² + 2s) + 9 = 0

add/subtract ( half the coefficient of the s- term )² to s² + 2s

3(s² + 2(1)s + 1 - 1) + 9 = 0

3(s + 1)² - 3 + 9 = 0

3(s + 1)² + 6 = 0 ( add 6 to both sides )

3(s + 1)² = - 6 ( divide both sides by 3 )

(s + 1)² = - 2 ( take the square root of both sides )

s + 1 = ± [tex]\sqrt{-2}[/tex] = ± i[tex]\sqrt{2}[/tex] ( subtract 1 from both sides )

s = - 1 ± i[tex]\sqrt{2}[/tex]

Thus

s = - 1 + i[tex]\sqrt{2}[/tex] , s = - 1 - i[tex]\sqrt{2}[/tex]

Answer:

Substitution property of equality

Step-by-step explanation:

Given

[tex]4x + 9 = 15[/tex] and [tex]x = 2y + 1[/tex]

Then

[tex]4(2y + 1) + 9 = 15[/tex]

Required

State the property

From the list of options, (d) answers the question.

This is so because:

Substitution property of equality states that

If [tex]a = b[/tex] then [tex]b = a[/tex]

In other words, both can replace one another.

So if [tex]x = 2y + 1[/tex], then 2y + 1 can be substituted for x in [tex]4x + 9 = 15[/tex]

So:

[tex]4x + 9 = 15[/tex]  becomes

[tex]4(2y + 1) + 9 = 15[/tex]

Hence, it is substitution property of equality

Answer:

[tex]y = 15.5[/tex]

Step-by-step explanation:

Given

[tex]Total\ Distance = 20km[/tex]

[tex]Walks\ Hours= \frac{3}{2}\ hours[/tex]

[tex]Walks\ Rate = \frac{3km}{1\ hour}[/tex]

Required

Determine the distance (y) covered by his car

First, we calculate the distance walked.

This is calculated as follows;

[tex]Distance = Walk\ Hours * Walk\ Rate[/tex]

[tex]Distance = \frac{3}{2}\ hours * \frac{3km}{1\ hour}[/tex]

[tex]Distance = \frac{3}{2}* 3km[/tex]

[tex]Distance = \frac{3* 3km}{2}[/tex]

[tex]Distance = \frac{9km}{2}[/tex]

[tex]Distance = 4.5km[/tex]

This means that he walked 4.5 km

The total distance can be expressed as a sum of distance covered while walking and distance covered by car.

i.e.

[tex]Walk + Car = Total[/tex]

Make Car the subject

[tex]Car = Total - Walk[/tex]

This gives

[tex]y = 20 - 4.5[/tex]

[tex]y = 15.5[/tex]

Hence, his car travelled 15.5km

Step-by-step explanation:

First solve g(x) by replacing x with 4

G(x) = x^2 = 4^2 = 16

Now replace x in f(x) with 16:

F(x) = 2x + 1 = 2(16) + 1 = 32 +1 = 33

Answer: Y [tex]\geq[/tex] [tex]\frac{1}{2}[/tex] x+ 20

              Y [tex]\leq[/tex] [tex]\frac{2}{3}[/tex] x+ 80

              X [tex]\geq[/tex] 1,200

             X  [tex]\leq[/tex] 1,850

Step-by-step explanation:

The system of inequalities which represents these constraints is y ≥ 20 + (1/2)x, y ≤ 80 + (2/3)x and 1200 ≤ x ≤ 1850

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represents Sally's monthly paycheck, and y represents her monthly savings.

Hence:

y ≥ 20 + (1/2)x

also:

y ≤ 80 + (2/3)x

and:

1200 ≤ x ≤ 1850

The system of inequalities which represents these constraints is y ≥ 20 + (1/2)x, y ≤ 80 + (2/3)x and 1200 ≤ x ≤ 1850

Answer:

The answer is B 7.5 hours.

Step-by-step explanation:

A. P. E. X

Sydney can clean her house in 7.5 hours.

Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output ("product") produced per the amount C ("cost") of resources consumed.

Here, Monica can clean her house in 5 hours

Monica's efficiency = 1/5

Let, Sydney cleans the house in x hours.

Sydney's efficiency = 1/x

They both together complete their work in 3 hours

Combined efficiency = 1/3

Now, according to question;

1/5 + 1/x = 1/3

(x+5)/5x = 1/3

3x + 15 = 5x

5x - 3x = 15

2x = 15

x = 15/2

x = 7.5

Thus, Sydney can clean her house in 7.5 hours.
