Ms. Reiger’s students found a total of 16 bird feathers. The line plot shows the lengths, in inches, of the bird feathers found by the students
Look at the line plot, and then select the two correct statements about the bird feathers.


The difference between the lengths of the shortest feather and the longest feather is 318 inches.

A. The difference between the lengths of the shortest feather and the longest feather is 238 inches.

B. The combined length of the two longest feathers is 828 inches.

C. The combined length of the shortest feather and the longest feather is 738 inches.

D. The combined length of the shortest feather and the longest feather is 618 inches.

Answer:

1/4

Step-by-step explanation:

we know that the lines A and B are parallel.

The term "parallel" implies that they will never meet each other, and to do so, the lines must have the same slope.

So the slope of line A is the same as line B (as for all parallel lines have the same slope)

So the slope of line B is also 1/4

Step-by-step explanation:

Gina says the cost is 8t, which means you can easily find out the cost of each t-shirt if you know the the total cost too. Bindi says the total cost was 192, which is completely useless on its own, but paired with Gina's info, you can get the answer. Divide 192 by 8, and you get the cost of each t-shirt.

Answer:

[tex]\frac{2}{81}[/tex]

Step-by-step explanation:

There is a common ratio between consecutive terms in the sequence

r = [tex]\frac{-\frac{2}{3} }{2}[/tex] = [tex]\frac{\frac{2}{9} }{-\frac{2}{3} }[/tex] = [tex]\frac{-\frac{2}{27} }{\frac{2}{9} }[/tex] = - [tex]\frac{1}{3}[/tex]

To find a term in the sequence multiply the previous term by - [tex]\frac{1}{3}[/tex] , then

a₅ = - [tex]\frac{1}{3}[/tex] × a₄ = - [tex]\frac{1}{3}[/tex] × - [tex]\frac{2}{27}[/tex] = [tex]\frac{2}{81}[/tex]

Answer:

B

Step-by-step explanation:

The set {126, 168, 189} has  21 as a common factor.

The set{154, 231} has  11 as a common factor.

If a number m is completely divisible by number n. Then number n will be the one factor of number m.

(a). Given set of number is, {126, 168, 189}

Now check,  21 is a common factor or not.

 [tex]\frac{126}{21}=6,\frac{168}{21}=8,\frac{189}{21}=9[/tex]

It is observed that all numbers are completely divisible by 21.

So that , 21 is common factor.

(b). Given set of number is, {154, 231}

      [tex]\frac{154}{11}=14,\frac{231}{11}=21[/tex]

It is observed that all numbers are completely divisible by 11.

Answer: $3,000

Step-by-step explanation:

The cost for a single person is:

Travel      £150

Hotel       £50 for each day

Spending money       £250

Hotel is the only one that changes per the number of days so the total cost for a single person for 7 days is:

= 150 + (50 * 7) + 250

= 150 + 350 + 250

= $750

There are 4 people so the total cost will be:

= 750 * 4 people

= $3,000

D is the second best answer. It is still incorrect.  If you simply subtract the x's don't cancel. B and C are both incorrect because you're not doing anything to adjust the ys.

the answer is A. If you simply add, the x's will cancel and you will be left with 11y = 22

y = 2

Given:

The value of car before two years = £10000

The value of the car decreases by 5% each year.

To find:

The present value of the car.

Solution:

The exponential decay model for present value is

[tex]y=a\left(1-\dfrac{r}{100}\right)^t[/tex]

Where, a is the initial value, r is the rate of decay and t is time in years.

Putting P=10000, r=5 and t 2, we get

[tex]y=10000\left(1-\dfrac{5}{100}\right)^2[/tex]

[tex]y=10000\left(1-0.05\right)^2[/tex]

[tex]y=10000\left(0.95\right)^2[/tex]

On further simplification, we get

[tex]y=10000(0.95)(0.95)[/tex]

[tex]y=9025[/tex]

Therefore, the present value of the car is £9025.

Step-by-step explanation:

By the interior angle theorem of triangles, the value of x is 5°.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know the sum of the interior angles in a triangle is 180°.

Given, In a triangle DEF the measure of angle D is 50⁰, the measure of angle E is 80⁰, and the measure of angle F is 10x .

Therefore, m∠D + m∠E + m∠F = 180°.

50° + 80° + 10x = 180°.

10x = 180° - 130°.

10x = 50°.

x = 5°.

So, The value of x is 5°.

Answer:

Step-by-step explanation:

13 blocks × (1 mile)/(20 blocks) = 13/20 mile = 0.65 mile

Tracker is inaccurate

The fitness tracker is inaccurate.

A ratio indicates the number of times one number contains another.

Given that, there are 20 blocks per mile.

20 blocks = 1 mile

1 block = (1/20) mile

13 block = (13/20) mile

13 block = 0.65 mile

Therefore, Tara walks 0.65 miles, not 0.71 miles.

Answer: 72

Plan A = 30 +0.15x

Plan B = 16 +0.20x

30+0.15x = 16+0.20x

subtract 16 from each side

14 +0.15x = 0.20x

subtract 0.15x from each side

14=0.05x

x = 14/0.05 = 280 minutes

280*0.15 = 42 +30 = $72

280 * 0.20 = 56 +16 = 72

280 minutes and cost $72 each
