Answer:

  more than 410

Step-by-step explanation:

For x miles, the second plan costs ...

  p2 = 50 +0.25(x -250)

For the first plan to be cheaper requires ...

  p1 < p2

  90 < 50 +0.25(x -250)

  40 < 0.25(x -250) . . . . . . subtract 50

  160 < x -250 . . . . . . . divide by 0.25

  410 < x . . . . . . . . . add 250

For more than 410 miles in one day, the unlimited plan would save money.

Answer:

0.2 m³/s

Step-by-step explanation:

Applying,

Q = vA.............. Equation 1

Where Q = Flow rate of  air in the pipeline, v = flow velocity of the air in the pipeline, A = cross sectional area of the pneumatic pipeline.

From the question,

Given: v = 20 m/s, A = 0.01 m²

Substitute these values into equation 1

Q = 20(0.01)

Q = 0.2 m³/s

Hence the flow rate of air in the pipeline is  0.2 m³/s

Answer:

6

Step-by-step explanation:

We need to find the slope

We have 2 points

(0,0) and (1,6)

m = (y2-y1)/(x2-x1)

   = (6-0)/(1-0)

   = 6/1

  = 6

y = 6x

The constant of proportionality is 6

Answer:

The constant of proportionality is 6.

Step-by-step explanation:

(0,0) and (1,6)

m = (y2-y1)/(x2-x1)

→ (6-0)/(1-0)

→ 6/1

So, y = 6x.

Answer:

n= 2x-6y

Step-by-step explanation:

So we might look at this and have an immediate panic attack, but if there is one thing we might look to to help us, it would be logarithms. Logarithms have many wonderful properties that will help us solve this equation. Let's get started:

1.  This is the starting equation. [tex](2^{\frac{1}{2} } )^{n} =\frac{2^x}{8^y}[/tex]

2. Let's use the power to power rule on the left and multiply 1/2 by n:

a. [tex]2^{\frac{1}{2}n } =\frac{2^x}{8^y}[/tex]

3. Next, lets take the log of both sides and use the properties of logarithms:

a. [tex]2^{\frac{1}{2}n } =\frac{2^x}{8^y}[/tex]

b. [tex]log(2^{\frac{1}{2}n }) =log(\frac{2^x}{8^y})[/tex]

c. One property we are allowed to use is bringing down the exponent on the left, and another property we can use is when you have the log of a fraction, that is the same thing as the log(numerator)-log(denominator)

d. [tex]\frac{1}{2}n *log(2) =log(2^x)-log(8^y)[/tex]

e. After we do this, we can use the same property of bringing down the exponent on the right side:

f. [tex]\frac{1}{2}n *log(2) =x*log(2)-y*log(8)[/tex]

g. After this, because log(2) and 1/2 are both numbers and are multiplied by n, we can divide them from both sides, and simplify:

h. [tex]\frac{1}{2}n =\frac{x*log(2)-y*log(8)}{log(2)}[/tex]

i. [tex]2(\frac{1}{2})n =2\frac{x*log(2)-y*log(8)}{log(2)}[/tex]

j. [tex]n =2\frac{x*log(2)-y*log(8)}{log(2)}[/tex]

k. After this, we must simplify the fraction because log(2)/log(2)=1, and log(8)/log(2)=3, these are both because 2^1=2 and 2^3=8 respectively:

l. [tex]n =2(\frac{x*log(2)}{log(2)}-\frac{y*log(8)}{log(2)} )[/tex]

m. Lastly, let's cancel and distribute:

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

o. [tex]n=2x-6y[/tex]

Answer:

1. (5)(8) = (4)(x)

Step-by-step explanation:

We have two chords intersecting each other.

Intersecting chords theorem states that when two chords cut each other, the product of the segments of one is equal to the product of the segments of the other.

Therefore, we would have:

(5)(8) = (4)(x)

Answer:

the answer is .5 I think I'm sorry if I'm wrong

Answer:

1 / 7

Step-by-step explanation:

Given the distribution above :

P(grade B or higher) can be defined explicitly as :

P(Grade A) + P(Grade B)

P(grade A) = 2/35

P(Grade B) = 3 / 35

Hence,

P(Grade B or higher) = 2/35 + 3/35 = 5/35 = 1/7

Answer:

The family has 1/4 of the strawberries left to snack on, or 31 left to snack on.

Step-by-step explanation:

Since they gave away 1/4 of the strawberries to their neighbor, and the others were used in a pie, that means that 1/4 of the strawberries remain. You do 124/4 in which 1/4 of that is 31, since 31x4 is equal to 124.

Step-by-step explanation:

In solving this question, remember the annotation SOHCAHTOA

1. We are given the value of the hypotenuse and we are to determine the value of the adjacent side. COS would be used to determine this value

Cos 26 = Adjacent / hypotenuse

cos 26 = x / 15

x / 15 =0.8988

x = 15 x 0.8988 = 13.5

2. We are given the value of the hypotenuse and we are to determine the value of the opposite side. SIN would be used to determine this value

Sin = opposite / hypotenuse

sin 49 = x / 24

0.7547 = x / 24

x = 0.7547 x 24

x = 18.1

3. We are given the value of the opposite side and we are to determine the value of the adjacent side. TAN would be used to determine this value

Tan = opposite / adjacent

tan 14 = 18 /x

18 / 0.2493 = 72.2

4.  We are given the value of the adjacent and we are to determine the value of the hypotenuse side. COS would be used to determine this value

cos 67 = opposite / hypotenuse

0.3907 = 5/x

x =5/  0.3907 = 12.8

to determine the missing angle

7. tan^-1 = opposite / adjacent

8. cos^-1 = adjacent / hypotenuse

9 = sin^-1 = opposite / hyotensue

Answer: D) The value of [tex]\sqrt{215}[/tex] is between 14.5 and 15

Step-by-step explanation:

Let's start by taking the squaring these numbers.

[tex]13^2=169\\13.5^2=182.25\\14^2=196\\14.5^2=210.25\\15^2=225[/tex]

215 is in between 14.5 squared and 15 squared. That means its square root will be between 14.5 and 15.5

Answer:

 15/7 < x < 13

Step-by-step explanation:

The triangle inequality requires that side lengths a, b, c satisfy ...

  a + b > c

  a + c > b

  b + c > a

These can let us write three inequalities for the side lengths given:

  6x -11 +3x -1 > 2x +3   ⇒   7x > 15

  6x -11 +2x +3 > 3x -1   ⇒   5x > 7

  3x -1 +2x +3 > 6x -11   ⇒   x < 13

The first two resolve to ...

  x > 15/7 ≈ 2.143

  x > 7/5 = 1.4

So, the final requirement is that ...

 15/7 < x < 13

Step-by-step explanation:

I don't see really the actual answer options (you made a bad copy here).

so, I can only tell you what it is in my own terms and you need to associate to the actual answer option.

based on real numbers (not complex or imaginary) we cannot use the square root function on negative numbers.

the domain defined what values can be used for x.

Answer:

y = -120

Step-by-step explanation:

Direct variation is

y = kx where k is a constant

9 = k(-3)

Divide each side by -3

9/-3 = k

-3 = k

y = -3x

Let x = 40

y = -3(40)

y = -120

Answer:

for the lengths, just double the numbrrs

1.5 -> 3

2.5 -> 5

bc the scale factor is two (the upper edge is given)

the angles are just the same, no matter the zoom factor

There are two polygons where B is greater than A.

One side in polygon A has a length of 2.5 and the corresponding length in polygon B is 5.

So, the scale factor is

[tex]\dfrac{5}{2.5}=2[/tex]

So, the missing sides in polygon B are

[tex]1.5\times2=3[/tex]

[tex]2.5\times 2=5[/tex]

The angles in polygon A will be the same as B as all the sides of the polygon have changed according to the scale factor.

So, the missing sides in polygon B are 3 and 5, and the angles in polygon A are [tex]53^{\circ}[/tex] and [tex]82^{\circ}[/tex].

Step-by-step explanation:

=========================================================

Explanation:

Rule: if |x| > k, then x < -k or x > k

Using that rule for the given inequality means we have these steps

|x-4| > 3

x-4 < -3  or x-4 > 3

x < -3+4 or x > 3+4

x < 1  or  x > 7 ..... choice E

-------------

Here's a visual way to see why this is the case.

|x-4| represents the distance from x to 4 on the number line.

When we say |x-4| > 3, we want to know which points are more than 3 units away from 4 on the number line.

We can plot 4 on the number line, and then measure 3 units below it (to get to 1) and then 3 units above it (to get to 7). If we're in the region 1 < x < 7, then we're within 3 units of 4 on the number line. Otherwise, we're more than 3 units away from the target we're after.

Answer:

length = 12

width = 15

Step-by-step explanation:

if you foil (x+7)(x+10) you get:

x²+17x-110 = 0

the factors are:

(x+22)(x-5) = 0

x = -22 and 5

we can dismiss the negative as irrelevant for a measure; therefore, x = 5

length = 5+7, or 12

width = 5+10, or 15
