Jayne evaluated an expression that has a value of StartFraction 1 Over 729 EndFraction. Which expression could Jayne have evaluated? Check all that apply.

Answer:

40

Step-by-step explanation:

The value of a right angle is 90° and <SQR is a fraction of <PQR.

Hence,  <PQS, which is the other fraction of <PQR, equals 90-50 and 90-50 is 40.

Or we can do it like this;

⇒ 180-90-50

⇒ 90 - 50

⇒ 40

Thus, Answer is 40.

Answer: 2.44 miles.

Step-by-step explanation:Answer:

2.44 miles

Step-by-step explanation:

Give the following :

Average miles to school = 12 miles per hour

Average Miles from school = 15 miles per hour

Total ride time : ( time to school + time from school) = 22 minutes = (22/60) = 0.3667

Recall:

Speed = distance / Time

Time = distance / speed

Let distance = d

For the scenario described :

d/12 + d/15 = 0.3667

(5d + 4d) / 60 = 0.3667

5d + 4d = 22

9d = 22

d = 22/9

d = 2.44 miles

Answer:D

Step-by-step explanation: answer D. 1/4x-1

slope = 1/4 so the coefficent (number attatched to x) is going to be 1/4

y=-1 when x=0

A. =-1/4

B= -1 but the coefficent is not 1/4

C=1

D=-1

D is the correct answer

Using the z-distribution, as we are working with a proportion, it is found that samples of 937 should be taken.

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In this problem, we have that:

Then, we solve for n to find the minimum sample size.

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 1.96\sqrt{\frac{0.675(0.325)}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.96\sqrt{0.675(0.325)}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.675(0.325)}}{0.03}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{1.96\sqrt{0.675(0.325)}}{0.03}\right)^2[/tex]

[tex]n = 936.4[/tex]

Rounding up, it is found that samples of 937 should be taken.

Answer:

$24

Step-by-step explanation:

1. MULTIPLY: 3 x 56 = 168

2. DIVIDE: 168 / 7 = $24

I hope this helps!

Based on multiplication we have found that 3/7 of $56 is equal to $24.

We are given that the expression 3/7 of $56

To determine 3/7 of $56, we can multiply 3/7 by $56.

Multiply 3/7 by $56:

(3/7) x $56 = (3 x $56) / 7

Calculate the numerator:

3 x $56 = $168

Divide the numerator by the denominator:

$168 / 7 = $24

Therefore, 3/7 of $56 is equal to $24.

Answer:

  3.9

Step-by-step explanation:

The right triangle is marked with the sides adjacent and opposite the angle. That suggests the relevant trig relation is ...

  Tan = Opposite/Adjacent

  tan(52°) = 5/x

  x = 5/tan(52°) ≈ 3.9

Work Shown:

C = 2*pi*r

6.28 = 2*3.14*r

6.28 = 6.28r

6.28r = 6.28

r = (6.28)/(6.28)

r = 1

The radius of the circle is 1 yard.

A = pi*r^2

A = 3.14*1^2

A = 3.14

The area is roughly 3.14 square yards.

The area of the trampoline  is mathematically given as

a = 3.14

Question Parameters:

You found one online that has a circumference of 6.28 yards

Generally, the equation for the Circumference   is mathematically given as

C = 2*pi*r

Thererfore

6.28 = 2*3.14*r

r = (6.28)/(6.28)

r = 1

In conclusion, where radius is

[tex]a= pi*r^2[/tex]

a = 3.14*1^2

a = 3.14

Answer:

The volume of a prism is given by ...

 V = Bh

Step-by-step explanation:

Here, the base is an equilateral triangle with side length 3 in. The area of such a triangle is given by

 A = (√3)4*s²

where s is the side length.

Your triangular prism has a base area of ...

 B = (√3)/4*(3 in)² = (9/4)√3 in²

so the volume is

 V = ((9/4)√3 in²)(6 in)

 V = (27/2)√3 in³

 V ≈ 23.383 in³

Answer:

Step-by-step explanation:

let the amount spent on popcorn be x and amount spent on drinks be y

If the total bill paid is  $17.94, then x+y =  $17.94

If she spend twice as much on popcorn as on drinks, then y = 2x

Substitute y = 2x into the original equation

x+y =  $17.94

x + 2x =  $17.94

3x =  $17.94

x =  $17.94/3

x = $5.98

Since y = 2x

y = 2($5.98)

y = $11.96

Therefore she spent  $5.98 on popcorn and $11.96 on drinks

Answer: D) The linear model shows a strong fit to the data

The actual strength of the relationship is unknown unless we have the actual values of each data point (so we can compute the correlation coefficient r), but the residuals are randomly scattered about both above and below the horizontal axis. This means we have a fairly good linear fit. If all of the points were above the line, or all below the line, or all residuals fit a certain pattern (eg: parabola), then it wouldn't be a good linear fit.
