Answer:

Jur 28 1/3 miles per gallon

Step-by-step explanation:

To find the miles per gallon, take the miles driven and divide by the gallons used.

Jur:  340/12 =28.333333 miles per gallon

Jack :  390/16 = 24.375 miles per gallon

Jur has better gas mileage because his number is higher

Answer:

Option B: y = 9x - 10.

Step-by-step explanation:

General equation of a straight line in the 2-D plane is given by:

y = mx + c; where m is the slope and c is the y-intercept.

The given equation of the line is y = 7x - 14; where m=7 and c=-14.

To make the line steeper, the gradient has to be increased. Therefore, Options A and C are incorrect because 5 is less than 7. This makes the Options B and D the remaining options because 9 is greater than 7.

To shift the y-intercept of this line up, the y-intercept has to be increased. Since -10 is greater than -14 and -18 is lesser than -14, therefore the latter option (Option D) is the incorrect option. So the correct answer is Option B: y = 9x - 10!!!

Answer:

P(2)=0.021942 approximately

P(2 or fewer)=0.02711 approximately

Step-by-step explanation:

[tex] P(x)=(n choose x) *p^x * q^{n-x} [/tex]

x is the number of successes desired

p is probability of getting a success per trial

n is the number of trials

q is 1-p

So n=15 and p=.4 here

And you want to know P(2) which means x is 2

Plug in this information

[tex] P(2)=(15 \text{ choose } 2) *.4^2 * .6^{15-2} [/tex]

Just plug into calculator...  P(2)=0.021942 approximately

For p(2 or fewer) you just do P(0)+P(1)+P(2)

I already found P(2)

You need to find P(1)

Once you get P(1), add that result to 0.021942.

Try to do part b and I will tell you if you got it right or not.

So P(2 or less) is P(0)+P(1)+P(2)

So to complete this we need to find P(1) and almost forgot P(0)...

We already have P(2).

P(0)=(15 choose 0) *.4^0*.6^(15-0)=0.00047

P(1)=(15 choose 1)  *.4^1 *.6^(15-1)=.004702

Now                                         P(2)=0.021942

Answer:

1 foot.

Step-by-step explanation

That is not the correct formula.  Correct is  V^2 = 2gh  where h = the height

so the equation is:

8^2 = 2*32* h

h = 64/ 64 = 1 foot.

Answer:

[tex]h=\frac{1}{8} feet[/tex]

Step-by-step explanation:

In order to be able to solve this problem you just have to clear the formula for height:

V=2gh

[tex]\frac{V}{2g}=H[/tex]

[tex]\frac{8}{64}=H[/tex]

[tex]\frac{1}{8}=H[/tex]

So the height from which the hammer is dropped is 1/8 feet.

Answer:

imaginary root

Step-by-step explanation:

7x^2 + 3 = 8x

Subtract 8x from each side

7x^2 -8x+ 3 = 8x-8x

7x^2 -8x+3 =0

This is in the form ax^2 +bx+c

The discriminant is b^2 -4ac

a=7 b=-8 c=3

b^2-4ac  = (-8)^2 -4(7)(3) = 64 - 84 = -20

Since this is negative, we have imaginary roots

Answer: The Answer Is 4) Hope it Helps!

Step-by-step explanation:

Answer:

Step-by-step explanation:

If a ≤ b < c are the length of the sides of a right triangle, then

a² + b² = c².

We have:

a =30 ft, b = 40 ft and c = 50 ft.

Check the equality:

L = 30² + 40² = 900 + 1600 = 2500

R = 50² = 2500

L = R

Answer:

Pretend that x and y represents the 2 numbers that we need to find.

According to the information, we know that:

x + y = 21

6x = y

Replace y in the first equation with 6x (because they are equal to each other according to the second equation):

x + y = 21

x + 6x = 21

7x = 21

x = 21/7 = 3

Now have two ways to find y, both will give us the same result:

3 + y = 21 ⇔ y = 21 - 3 = 18

6 · 3 = y ⇔ y = 18

So the numbers that we need to find are 3 and 18.

Answer:

3 and 18.

Step-by-step explanation:

If one number is x then the other is 6x.

So, x + 6x = 21

7x = 21

x = 3.

The other number is 21 - 3 = 18.

Answer:

(x – h)2 + (y – k)2 = r2

Step-by-step explanation:

If the center of the circle were moved from the origin to the point (h, k) and point P at (x, y) remains on the edge of the circle  the equation of the new circle

(x – h)2 + (y – k)2 = r2

Based on Pythagorean theorem, and the location of the center of the

circle, (h, k), the equation of the circle is represented by the option;

The general form of the equation of the circle is (x - h)² + (y - k)² = r²

Where;

(h, k) = The center of the circle

r  = The radius of the circle

A description of the equation of the circle is as follows;

With regard to a location on the edge (circumference), of the circle, (x, y),

where, the center of the circle is (h, k), by Pythagorean the sum of the

square of the length of the horizontal side, (x - h), and the square of the

vertical side (y - k), of the right triangle formed gives the square of the

radius of the circle.

Therefore, the equation of the new circle can be represented by the equation;

The above equation is the general form of the equation of a circle.

hours:2134 = 3 weeks

hours: 1176 = 2 weeks

Answer: option b

Step-by-step explanation:

It is important to know that, by definition, the rule for 180 degrees counterclockwise rotation is:

[tex](x,y)[/tex]→[tex](-x,-y)[/tex]

Therefore, given the point (1, -6) we can find the image obtained for  for a 180° counterclockwise rotation about the origin by applying the rule mentioned before.

Then, the image is:

 [tex](1,-6)[/tex]→[tex](-(1),-(-6))=(-1,6)[/tex]

Answer:

The correct answer option is b. ( -1, 6).

Step-by-step explanation:

We are given a point which is rotated 180 degrees counterclockwise about the origin (0, 0). We are to find the coordinates of the image of this point after the rotation.

The rule for rotating a point 180 degrees counterclockwise is:

(x, y) ---> (-x, -y)

So for the given point, the coordinates of the image will be:

(1, -6) ---> (-1, -(-6)) ---> (-1, 6)

Answer:

The radius of the circle is 14 inches.

Step-by-step explanation:

How is the circumference of a circle related to its radius?

[tex]\displaystyle \text{Circumference} = \pi\times \text{Diameter} = \pi\;(2\times \text{Radius})[/tex].

In brief,

[tex]\text{Circumference} = 2\pi\times \text{Radius}[/tex].

For this question,

Divide both sides of the equation by [tex]2\pi[/tex]:

[tex]\displaystyle \frac{\text{Circumference}}{2\pi} = \text{Radius}[/tex].

[tex]\displaystyle \text{Radius} = \frac{\text{Circumference}}{2\pi} = \frac{28\pi}{2\pi} = 14[/tex].

In other words, the radius of this circle is 14 inches.

The first step will be to open the bracket i.e multiply -4 with 3 and -5x which is also called distributive law

Step-by-step explanation:

-4(3-5x)>-6x+9

We need to solve the above inequality

The first step will be to open the bracket i.e multiply -4 with 3 and -5x which is also called distributive law

(-4*3) (-4*-5x) >-6x+9

-12 +20x >-6x+9

-12 + 20x >-6x+9

The next step will be to add +12 on both sides

-12 + 20x +12 >-6x+9+12

20x  >-6x+21

The next step will be to add +6x on both sides

20x +6x  > -6x+21 +6x

26x > 21

x > 21/26

By using the concept of slope of a Straight line,we arrive to the conclusion that the equation of line through (2,-4) and having slope off 3/5 is  y = - (1/2)x - 26/5.

The slope of this Straight line is given as=3/5

Thus,the equation of the straight line becomes y=(3/5)x [tex]+[/tex]c.

Now,if substituting the Slope of the line in the equation of this line.

y=(3/5)x [tex]+[/tex]c.

In the point(2,-4):

-4=(3/5)(2) [tex]+[/tex] c

-4=(6/5) [tex]+[/tex] c

c=-4-(6/5)

  = - 26/5

Therefore, the final equation is y= - (1/2)x - 26/5
