Answer:

108quartz

Step-by-step explanation:

Volume of a cylinder = πr²h

r is the radius

h is the height

If A cylindrical container can hold 4 quarts of water, then;

4 = πr²h ...... 1

Let the volume be x of the radius and height at tripled

h1 = 3h

r1 = 3r

X = πr1²h1

X = π(3r)²(3h)

X = 9πr²(3h)

X = 27πr²h .... 2

Divide 1 by 2

4/x = πr²h/27πr²h

4/x = 1/27

Cross multiply

x = 4×27

x = 108

Hence the container can hold 108quartz of water of the radius and height was tripled.

Step-by-step explanation:

The fractions which are equivalent to the fraction [tex]\frac{9}{6}[/tex] from the given options are [tex]\frac{3}{2}[/tex] and [tex]\frac{12}{8}[/tex], which are options (A) and (C).

Given a fraction [tex]\frac{9}{6}[/tex].

It is required to find the fraction which is equivalent to the given fraction.

If two fractions are equivalent, then they will be proportional.

The fraction [tex]\frac{9}{6}[/tex] can be written as [tex]\frac{3*3}{2*3}[/tex].

Here, when 3 gets canceled, the resulting fraction is [tex]\frac{3}{2}[/tex].

So, [tex]\frac{3}{2}[/tex]  is equivalent to [tex]\frac{9}{6}[/tex].

And, [tex]\frac{3}{2}[/tex] is the simplest fraction that cannot be simplified further.

So, any number multiplied by it both on the numerator and denominator will be an equivalent fraction.

Multiplying both the numerator and denominator of the fraction [tex]\frac{3}{2}[/tex] by 4, the resulting fraction is [tex]\frac{12}{8}[/tex].

Hence, the correct options are (A) and (C).

Answer:

x-intercept = 3

y-intercept = - 6

Step-by-step explanation:

The intersection of the line with the x-axis is known as the x-intercept and it's calculated by making y = 0.

Also, the intersection of the line with the y-axis is known as the y-intercept and it's calculated by making x = 0.  

Given the following data;

Equation of straight line is [tex]y = 2x - 6[/tex]

To find the intersection;

When y = 0, the equation crosses the x-axis.

y = 0;

Substituting into the equation, we have;

0 = 2x - 6

2x = 6

x = 6/2 = 3

x = 3

(x, y) = (3, 0) on the x-axis.

When x = 0, the equation crosses the y-axis.

x = 0;

Substituting into the equation, we have;

y = 2(0) - 6

y = 0 - 6

y = -6.

(x, y) = (0, -6) on the y-axis.

Therefore, the coordinates of the intersection of the graph is (3, 0) and (0, -6).

Answer:

The correct option is d.

Step-by-step explanation:

The directional hypothesis is:

[tex]H_{a}:\mu>\mu_{0}[/tex]

The sample size is, n = 40.

The significance level is:

[tex]\alpha =1-0.95=0.05[/tex]

Use the t-table to compute the right-tailed t-critical value as follows:

[tex]t_{\alpha,\ (n-1)}=t_{0.05, (40-1)}[/tex]

             [tex]=t_{0.05, 39}\\\\\approx t_{0.05, 40}\\\\=1.684\\\\\approx 1.685[/tex]

The value is positive since the directional hypothesis suggests that the test is right tailed.

The correct option is d.

Answer:

The minimum amount of time required is 74.7 seconds.

Step-by-step explanation:

The question can be solved in two cases:

i. diagonal swimming of Brandon across the river

ii. Running of the rest distance by Brandon.

Case I: Since he would swim diagonally across the river, then the diagonal distance can be determined by applying appropriate trigonometric function.

Let the diagonal be represented by x, an included angle θ = [tex]45^{o}[/tex] is formed at his starting point (angle formed by the diagonal and the length of the width of the river).

So that:

Cos θ = [tex]\frac{adjacent}{hypotenuse}[/tex]

Cos [tex]45^{o}[/tex] = [tex]\frac{70}{x}[/tex]

x = [tex]\frac{70}{Cos 45^{o} }[/tex]

  = 98.995

x = 99 m

The diagonal distance covered by Brandon is 99 m.

The time to cover this distance can be calculated by:

speed = [tex]\frac{distance}{time}[/tex]

time = [tex]\frac{distance}{speed}[/tex]

Given that his swimming rate is 2 m/s, then:

time = [tex]\frac{99}{2}[/tex]

        = 49.5

The time taken by Brandon to swim diagonally is 49.5 seconds.

Case II: Since he want to cover a total distance of 250 m;

remaining distance to be covered = 250 - 99

                                                         = 151

time = [tex]\frac{distance}{speed}[/tex]

Given that he runs at 6 m/s, then;

time = [tex]\frac{151}{6}[/tex]

       = 25.1667

The time taken by Brandon to run the remaining distance is 25.2 seconds.

The minimum amount of time required = time taken by Brandon to swim diagonally + time taken by Brandon to run the remaining distance

                                 = 49.5 + 25.2

                                 = 74.7

The minimum amount of time required is 74.7 seconds.

Minimum amount of time to reach the desired point is   79.5 s

Brandon is on one side of a river

The width of the river =  70 m

Brandon wants to reach a point that is 250 m downstream of opposite side as quickly as possible by swimming diagonally across the river then running the rest of the way.

The swimming speed of Brandon =   2 m/s

The speed of running of Brandon = 6 m/s

Let us consider that the included angle be 45°

[tex]\rm cos \; \theta = \dfrac{70}{x} \\\\cos \; 45 = \dfrac{70}{x} \\\x = \dfrac{70}{0.707} \approx 99[/tex]

So the distance traveled by Brandon in water is 99 m

As the swimming speed of Brandon is given 2 m/s

So the time taken by Brandon to cross the river is given as follows

[tex]\rm Time = \dfrac{Distance}{Speed}[/tex]

[tex]\rm Time \; to\; cross\; the\; river = \dfrac{99}{2} = 49.5 \; s[/tex]

Let the horizontal distance covered by Brandon by swimming is H

So from Pythagorean theorem we can write

[tex]\rm H = \sqrt{99^2 -70^2 } = 70[/tex]

The distance that is left to be traveled by running is  250 - 70 = 180 m  

So  Time taken in running to reach the point by running = 180/6 = 30 s

So the  time to reach the desired point = 49.5 + 30 =   79.5 s
