Which of the following is the correct window of time we can expect to the population of kids to take cleaning their house?

Between ______ hours and _____ hours.

Answer:

There is no real solution

Step-by-step explanation:

If you are finding the square root of a number, it cannot be negative. No number can be multiplied by itself to get a negative number. Negative numbers multiplied with themselves make a positive number. Positive numbers are obviously going to stay positive. Therefore there is no square root of -9

Answer:

5:19

Step-by-step explanation:

You would just add 5 and 4 and 10 to get 19 and since there are 5 peaches it would be 5:19.

The volume of the cylinder is approximately 351.9 cubic centimeters.

A cylinder is a 3-D figure that has a radius and a height.

The volume of a cylinder is given as πr²h.

Example:

The volume of a cup with a height of 5 cm and a radius of 2 cm is

Volume.

= 3.14 x 2 x 2 x 5

= 62.8 cm³

We have,

The volume of a cylinder can be calculated using the formula:

V = πr²h,

where r is the radius of the base and h is the height.

Since the base diameter is given as 8 centimeters, the radius is half of that or 4 centimeters.

Substituting these values into the formula, we get:

V = π (4 cm)² (7 cm)

V ≈ 351.86 cm³

Rounding this answer to the nearest tenth gives a final answer of V ≈ 351.9 cm^3.

Therefore,

The volume of the cylinder is approximately 351.9 cubic centimeters.

Step-by-step explanation:

There is one line of symmetry for each side of the pentagon.

Since only 3 vertical lines can be drawn across a pentagon that will divide it equally, hence there are 3 lines of symmetry in the regular pentagon

Step-by-step explanation:

Answer:

y = 1/4x - 1.75

Step-by-step explanation:

standard form is y = mx + b

to get m you need to calculate the slope between the given points

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

m = (-1 - (-3))/(3 - (-5)) = 2/8 = 1/4

now you need to find the constant b by plugging in one of your points

y = 1/4x + b

-1 = 1/4(3) + b

b = -1 - (3/4)

b = -7/4 or -1.75

Answer:

0 = x - 4y - 7

Step-by-step explanation:

Moving from (-5, -3) to (3, -1), we see that x (the run) increases by 8 and y (the rise) incrases by 2.  Thus, the slope of the line connecting these two points is m = rise / run = 2/8, or 1/4.

Use the slope-intercept form of the equation of a straight line first:

y = mx + b becomes          -1 = (1/4)(3) + b, or (after multiplying all three terms

                                           by 4)  -4 = 3 + 4b.  Then 4b = -7, and b = -7/4.

Then the desired equation is    y  = (1/4)x - 7/4, or

4y = x - 7, or

0 = x - 4y - 7.  This is the desired equation in standard form.

Answer:

He need to cover 275 miles for same cost for both plans

Step-by-step explanation:

Let x be the no. of miles

Case 1 :

Initial fee = $38

Additional cost of 1 mile = 0.13

Additional cost of x miles = 0.13x

So, total cost = 38+0.13x

Case 2 :

Initial fee = $49

Additional cost of 1 mile = 0.09

Additional cost of x miles = 0.09x

So, total cost = 49+0.09x

Now we are supposed to find amount of driving do the two plans cost the same

So, 38+0.13x=49+0.09x

0.13x-0.09x=49-38

0.04x=11

[tex]x=\frac{11}{0.04}[/tex]

x=275

Hence he need to cover 275 miles for same cost for both plans

Answer:

Option B

Step-by-step explanation:

When all options are graphed along withe the equation in the question,

[tex]y=-4x[/tex] does not intercept with [tex]y=-4x-12[/tex].

This means that y=-4x and y=-4x-12 will have no solution.

Option B should be the correct answer.

Answer:

B. y= 2x–15

Step-by-step explanation:

The equation that represents the line that passes through the points (8, 1) and (10,5) is y= 2x–15

"x" is found on the left hand side of the bracket and "y" is found on the right hand side of the bracket :)

(8, 1) and (10, 5)

x in the first bracket is 8 and x in the second bracket is 10.

y in the first bracket is 1 and y in the second bracket is 5.

When this equation is applied to find the value for y we get:

y= 2x-15

y= 2(8)-15

y= 16-15

y= 1

y= 2x-15

y= 2(10)-15

y= 20-15

y= 5

We got back the values of y and this means that the equation was correctly chosen and the answer is correct :)

Answer:

y=3x−4

Step-by-step explanation:

find the tangent line to f(x)=x2−3x+5 at x=3

First, find the value of the function at the given point: y0=f(3)=5

Second, find the slope of the tangent line, which is the derivative of the function, evaluated at the point:  m=f′(3)

Find the derivative:  f′(x)=2x−3

Next, we evaluate the derivative at the given point to find the slope.

m=f′(3)=3

Finally, the equation of the tangent line is  y−y0=m(x−x0)

Plug the values that we found, we get that  y−(5)=3(x−(3))

So basically: y=3x−4

Answer:

C. 4123.

Step-by-step explanation:

We calculate the cost of a gram of cat food for each package.

Pack 1: Cost of 1 gram = total cost / number of grams

= 39.99 / (24 * 250)

= $0.00665 '

Pack 2: The cost is  24.99 / (12 * 300)

= $0.00694.

In a similar way

Pack 3:  The cost is $ 0.0722

Pack 4: The cost is $0.00642 .
