Answer:

4 times

Step-by-step explanation:

Given that the sum of all the numbers => 3+4+5+6+7+8+9+10 = 52

And we are to divide it into two sets such that the sum of set B is three times the number of sum of set A => Sum B = 3 * Sum A

Hence Total sum = Sum B + Sum A

Total sum ÷ 4 = 52 ÷ 4 = 13.

Since Sum B = (3 * Sum A) => (3 * 13 ) = 39

Therefore Sum B = 39 and Sum A = 13

To divide them into two sets

Sum A = (10, 3) = 13: Sum B = ( 4, 5, 6, 7, 8, 9) = 39

Sum A = (9, 4) = 13: Sum B = (3, 5, 6, 7, 8, 10) = 39

Sum A = (8, 5) = 13: Sum B = (3, 4, 6, 7, 9, 10) = 39

Sum A = (7, 6) = 13: Sum B = (3, 4, 5, 8, 9, 10) = 39

Hence, the correct answer is 4 times

Answer:

Here you go sorry.

Step-by-step explanation:

Question 1.

y = 4x - 8 has a slope of 4. Since parallel lines have equal slopes, the slope of your new line will also be 4.

Now, you have a point (3,9) and a slope 4. Use the Point-Slope Form for the equation of a line.

y - y1 = m(x - x1)

y - 9 = 4(x - 3)

y - 9 = 4x - 12

y = 4x - 3

Question 2.

Since it is parallel, it must have the same slope.

y = (1/2)x + b

Find b from the given point.

4 = (1/2)(2) + b

b = 3

y = (1/2)x + 3

Answer:

2(a) 30°

(b) 48,59°

(c) 31,4485°

(d) 33,005565°

Answer:

Step-by-step explanation:

Step one:

given

A= 260ft^2

W= 2x + 4

B=8x + 2

Step two:

A=L*W

260=(2x+4)*(8x + 2)

open bracket

260=16x^24x+32x+8

16x^2+56x-252=0

Solving using quadratic formula

the roots are

x=-6.0

x= 2.6

Hence the value of x= 2.6ft

Answer:

Abdul's age=20 y/o

Grandpa's age=80y/o

Step-by-step explanation:

let Abdul's age be 'x'

so, grandpa's age=4x

Grandpa's age 10 yrs ago= 4x-10

according to the question, grandpa's age 1o yrs ago=7(x-10)

so, 4x-10=7(x-10)

     4x-10=7x-70

by substituting,

     70-10=7x-3x

     60=3x

     60/3=x

      20y/o=x

so, 4x=20*4=80 y/o

Answer:

64 : 1.

Step-by-step explanation:

Ratio of the volumes is 16^3 to 4^3

= 4096 : 64

= 64 : 1.

The statement that describes the graph of the system of equations is:

C. The lines intersect at (1.6, 1.4).

Here, we have,

To determine the description of the graph of the system of equations:

1.5x + 0.2y = 2.68

1.6x + 0.3y = 2.98

We can start by comparing the slopes of the two lines.

The equations are in the form y = mx + b, where m represents the slope.

In the first equation, the slope is 0.2, and in the second equation, the slope is 0.3.

Since the slopes are different, we can conclude that the lines are not parallel (option A) or overlapping at all points (option B).

To determine the point of intersection, we can solve the system of equations.

By using any appropriate method, we find that the lines intersect at (1.6, 1.4) (option C).

Therefore, the statement that describes the graph of the system of equations is:

C. The lines intersect at (1.6, 1.4).

Answer:

The water level is rising at the rate 0.238 cm per second

Step-by-step explanation:

Let the radius and height of water at time t be r and h respectively.

Height of cup =H= 8 cm

Radius of cup = R = 4 cm

By symmetry

[tex]\frac{r}{h}=\frac{4}{8} \\r=\frac{1}{2}h ---1[/tex]

Volume of water at time t , [tex]V= \frac{1}{3} \pi r^2 h[/tex]

[tex]\frac{dV}{dt}=\frac{1}{3}\pi 2r \frac{dr}{dt} h+\frac{1}{3} \pi r^2 \frac{dh}{dt}\\\frac{dV}{dt}=\frac{1}{3}\pi r (2 \frac{dr}{dt} h+ r \frac{dh}{dt})[/tex]

With 1

[tex]\frac{dr}{dt}=\frac{1}{2} \frac{dh}{dt}[/tex]

So,

[tex]\frac{dV}{dt}=\frac{1}{3}\pi (\frac{1}{2}h) (2 (\frac{1}{2} \frac{dh}{dt}h)+ r \frac{dh}{dt})\\\frac{dV}{dt}=\frac{1}{3}\pi (\frac{1}{2}h) ( \frac{dh}{dt}h+ r \frac{dh}{dt})\\\frac{dV}{dt}=\frac{1}{3}\pi (\frac{1}{2}h) ( h+\frac{1}{2}h) \frac{dh}{dt}\\\frac{dV}{dt}=\frac{1}{6}\pi h(\frac{3h}{2}) \frac{dh}{dt}\\\frac{dV}{dt}=\frac{1}{6}\pi (\frac{3h^2}{2}) \frac{dh}{dt}\\\frac{dV}{dt}=\frac{1}{12}\pi 3h^2 \frac{dh}{dt}[/tex]

We are given that Water is poured into a conical paper cup at the rate of 3 cubic centimeters  (cm) per second (s).

We are supposed to find how fast the water level is rising at the instant the water is 4 cm deep.

So,[tex]\frac{1}{12}\pi 3(4)^2 \frac{dh}{dt}=3\\\frac{dh}{dt}=\frac{3 \times 12}{\pi 3(4)^2 }=0.238[/tex]

Hence the water level is rising at the rate 0.238 cm per second

The radius in terms of height is [tex]\mathbf{r =\frac 12h}[/tex], while the water level increases at 0.239 cm per second when the height is 4 cm

(a) Radius in terms of height

The given parameters are:

[tex]\mathbf{h = 8cm}[/tex] --- height

[tex]\mathbf{r = 4cm}[/tex] --- radius

The above parameters can be written as:

[tex]\mathbf{r :h =4cm : 8cm}[/tex]

[tex]\mathbf{r :h =4 : 8}[/tex]

Express as fractions

[tex]\mathbf{\frac rh =\frac 48}[/tex]

[tex]\mathbf{\frac rh =\frac 12}[/tex]

Multiply both sides by h

[tex]\mathbf{r =\frac 12h}[/tex]

(b) How fast the water is rising

The volume of a cone is:

[tex]\mathbf{V = \frac 13 \pi r^2h}[/tex]

Differentiate with respect to time

[tex]\mathbf{V' = \frac 13 \pi(2rh\ \frac{dr}{dt} + r^2\frac{dh}{dt})}[/tex]

When the water is 4cm deep, then the radius is 2cm using [tex]\mathbf{r =\frac 12h}[/tex]

So, we have:

[tex]\mathbf{V' = \frac 13 \pi(2 \times 2 \times 4\times \frac{dr}{dt} + 2^2\frac{dh}{dt})}[/tex]

[tex]\mathbf{V' = \frac 13 \pi(16 \frac{dr}{dt} + 4\frac{dh}{dt})}[/tex]

Also, we have:

[tex]\mathbf{r =\frac 12h}[/tex]

Differentiate with respect to time

[tex]\mathbf{\frac{dr}{dt} = \frac{1}{2}\frac{dh}{dt}}[/tex]

So, we have:

[tex]\mathbf{V' = \frac 13 \pi(16 \times \frac{1}{2}\frac{dh}{dt} + 4\frac{dh}{dt})}[/tex]

[tex]\mathbf{V' = \frac 13 \pi(8\frac{dh}{dt} + 4\frac{dh}{dt})}[/tex]

[tex]\mathbf{V' = \frac 13 \pi(12\frac{dh}{dt})}[/tex]

Expand

[tex]\mathbf{V' = 4\pi\frac{dh}{dt}}[/tex]

The volume increases at 3 cm^3 per second.

So, we have:

[tex]\mathbf{3 = 4\pi\frac{dh}{dt}}[/tex]

Divide both sides by 4

[tex]\mathbf{0.75 = \pi\frac{dh}{dt}}[/tex]

Divide both sides by pi

[tex]\mathbf{0.239 = \frac{dh}{dt}}[/tex]

Rewrite as:

[tex]\mathbf{\frac{dh}{dt} = 0.239}[/tex]

Hence, the water level increases at 0.239 cm per second when the height is 4 cm
