Answer: she can run [tex]6\dfrac54[/tex] mile sin 1 hour.

Step-by-step explanation:

Given : Distance run by Jasmine in [tex]\dfrac23[/tex] of an hour = [tex]4\dfrac56\text{ miles}=\dfrac{24+5}{6}\text{ miles}[/tex]

[tex]=\dfrac{29}{6}[/tex] miles

Distance run by Jasmine in 1 hour = [tex]\dfrac{29}{6}\times\dfrac{3}{2}=\dfrac{29}{4}[/tex] miles.

[tex]=6\dfrac{5}{4}[/tex]   miles.

Hence, she can run [tex]6\dfrac54[/tex] mile sin 1 hour.

Answer:

Your friend is wrong.

Step-by-step explanation:

Since we have that you spend c dollars for p identical pairs of pants. We can represent this using:

C = kP.

Where k is the price for one pair of pants whereby the amount of dollars you spend depends on the number of pants picked.

C is the dependent variable here, depending on P and P is independent. Therefore, you have only one independent variable which is P.

Answer:

B'(- 2, 2 )

Step-by-step explanation:

Assuming the dilatation is centred at the origin, then multiply the coordinates of B by the scale factor 2, that is

B(- 1, 1 ) → B'(2(- 1), 2(1) ) → B'(- 2, 2 )

Answer:

1760 sqft

Step-by-step explanation:

10% is 0.1 in decimal, since its increasing, it would be 1.1

1600 times 1.1 is 1760.

in this condition "of" is considered as multiply(×) so the questions form in maths form is 77% × 192

because it is multiplication sign we multiply 77×192=14784 dont forget the percentage % percent is /100 so 14784/100 = 147.84.

Answer:

number of dimes is 8

number of quarters is 15

Step-by-step explanation:

let 'd' = number of dimes

let 'd+7' = number of quarters

.10d + .25(d + 7) = 4.55

.10d + .25d + 1.75 = 4.55

.35d = 2.80

d = 8

q = 7 + 8

Answer:

y = -3x - 3

Step-by-step explanation:

the y-intercept is -3 as shown in the graph, so, b = -3

if you count, the rise is 3 and the run is -1, so the slope will be -3/1

-3/1 equals to -3

y = -3x - 3

Answer:

y = –3x – 3

Step-by-step explanation:

m = the slope which is 3/1, or 3. Since the line is going from the bottom right corner to the top left, it is a negative slope so –3.

b = the y-intercept which is –3.

So,

y = –3x – 3

Hope this helps! :)

Answer: all you do is find out all the factors of that number. Then you look to see if there is a factor that is the same for the other number. The answer is 1,3,9. So the common factors are 1,3,9.

Answer: 360 people

Step-by-step explanation:

162 people who took the survey represented 45% of the total participants.

Assume the total participants is x.

The expression would be;

162 = 45% * x

x = 162/45%

x = 360 people

Hello!

[tex]\large\boxed{x = 4.21in}[/tex]

Use the Pythagorean Theorem to solve:

a² + b² = c²

We are given the Hypotenuse (c) and one of the legs (b), so we can plug those values in to solve for a:

a² + (6.8)² = 8²

a² + 46.24 = 64

Subtract 46.24 from both sides:

a² = 17.76

Square root both sides:

a = √17.76

a ≈ 4.21 = x

Answer:

yes because they are supplementary

- older brother

Answer:

2.053 hours

Step-by-step explanation:

From the question,

A half marathon is around 13 miles. Brian can run about 6 1⁄3 miles per hour.

If Brian keeps his pace, how long will it take him to run a half marathon?

This is calculated as:

6 1/3 miles = 1 hour

13 miles = x hour

Cross Multiply

6 1/3 miles × x hour = 13 miles × 1 hour

x hour = 13 miles × 1 hour/6 1/3 miles

x hour = 13 ÷ 6 1/3 miles

x hour = 13 ÷ 19/3

x hour = 13 × 3/19

x hour = 39/19

x hour = 2.0526315789 hours

Approximately = 2.053 hours

It will take him 2.053 hours to run a half marathon.

Slope of the tangent line at x=-1

[tex](\frac{dy}{dx})_{x=-1} = e^{-5}[/tex]

Step-by-step explanation:

Explanation:-

Given function

                            y = f(x) = e ˣ⁻⁴  ...(i)

       Differentiating equation (i) with respective to 'x' , we get

                         [tex]\frac{dy}{dx} = e^{x-4} \frac{d}{dx} (x-4)[/tex]

                       [tex]\frac{dy}{dx} = e^{x-4} (1)[/tex]

Slope of the tangent line

                       [tex](\frac{dy}{dx})_{x=-1} = e^{-1-4} = e^{-5}[/tex]

x < [tex]\frac{33}{4}[/tex]

Step-by-step explanation:

Given

- 4x + 35 > 2 ( subtract 35 from both sides )

- 4x > - 33

Divide both sides by - 4, reversing the symbol as a result of dividing by a negative quantity.

x < [tex]\frac{33}{4}[/tex]

Answer:

Step-by-step explanation:

V = 1/3 pi r^2 h

r = d/2

r = 6/2 = 3

h = 4.5

V = 1/3 *3.14 * 3^2 * 4.5

V = 1/3 * 3.14 * 9 * 4.5

V = 1/3 * 127.17

V = 42.39
