What is the quotient? 987 ÷ 6 This model describes the division calculation. Start with the greatest multiple of 100 that can be multiplied by the divisor with going over the dividend. Enter a number in each box to correctly complete the model and quotient.

Answers

Answer:

164.5

Step-by-step explanation:

987/6

164.5

The Quotient when 987 is divided by 6 is 164.

What is the Quotient?

The dividend is the number that is being divided, and the divisor is the number that is being divided. The quotient is the end result of division.

 

Since we need to find the quotient of 987 when it is divided by 6. Therefore, we can write the quotient as,

Quotient = 987 ÷ 6

               = 987 / 6

               = 164

Hence, When we divide 987 by the 6 we will get 164 as Quotient.

Is (1, 5) a solution to the following system of equations? Show and explain why or why not.

[tex]f(x)=3x+2[/tex]
[tex]g(x)=[x-1]+1[/tex]

Answers

Answer:

The solution(s) to a system of equations is the point(s) of intersection.

To find the solution, equate the equations and solve for x to find the x-coordinate:

[tex]\implies f(x)=g(x)[/tex]

[tex]\implies 3x+2=[x-1]+1[/tex]

[tex]\implies 3x+2=x[/tex]

[tex]\implies 2x=-2[/tex]

[tex]\implies x=-1[/tex]

Now substitute the value of x into one of the equations to find the y-coordinate of the solution:

[tex]f(-1)=3(-1)+2=-1[/tex]

So the solution to this system of equations is (-1, -1)

Therefore, (1, 5) is NOT a solution to the system of equations.

The circumference of a circle is 35 13/21 in.

What is the approximate diameter of the circle?

Use 22/7 for pi.

Enter your answer as a mixed number in simplest form in the box.

in.

Answers

Solution:

We know that:

[tex]\large\tex\text{Circumference of circle} = 2\pi r = 35 \dfrac{13}{21} \ \tex\text{inches}[/tex]

[tex]\large \pi = \dfrac{22}{7}[/tex]

Somehow, we need to find the radius of the circle. To do that, we need to isolate 'r'.

Isolating 'r':

To isolate "r", we need to divide both sides by 2, then divide both sides by 22/7. You can also multiply 22/7 and 2 and then divide the result both sides to isolate "r".

Step-1: Divide both sides by 2.

[tex]2\pi r = 35 \dfrac{13}{21} \ \tex\text{inches} \\\\\\\ \dfrac{2\pi r}{2} = 35 \dfrac{13}{21} \div 2 \\\\\\ \pi r = \dfrac{35 \times 21 + 13}{21} \div 2 \\\\\\\pi r = \dfrac{748}{21} \times \dfrac{1}{2} \\\\\\\ \pi r = \dfrac{374}{21}[/tex]

Step-2: Divide π both sides.

[tex]\dfrac{\pi r}{\pi} = \dfrac{374}{21} \div \pi \\\\\\ r = \dfrac{374}{21} \div \dfrac{22}{7} \\\\\\ r = \dfrac{374}{21} \times \dfrac{7}{22} \\\\\\ r = \dfrac{17}{3}[/tex]

Now, let's multiply the radius by 2 to obtain the diameter.

Obtaining the diameter:

[tex]\tex\text{Diameter = 2(Radius)} \\\\\\ \tex\text{Diameter} = 2(\dfrac{17}{3} ) \\\\\\ \boxed{\bold{Diameter = \dfrac{34}{3}}}[/tex]

[tex]\\ \rm\rightarrowtail \pi d=35\dfrac{13}{21}[/tex]

d is diameter

[tex]\\ \rm\rightarrowtail \pi d=\dfrac{748}{21}[/tex]

[tex]\\ \rm\rightarrowtail d=748/21\pi[/tex]

[tex]\\ \rm\rightarrowtail d=11.34in[/tex]

Twelve different video games showing substance use were observed and the duration of times of game play​ (in seconds) are listed below. The design of the study justifies the assumption that the sample can be treated as a simple random sample. Use the sample data to construct a 98% confidence interval estimate of ​o, the standard deviation of the duration times of game play.

The confidence interval estimate is ___

Answers

Using the t-distribution, as we have the standard deviation for the population, it is found that the confidence interval estimate is (4044.2, 4653.4).

What is a t-distribution confidence interval?

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.

The critical value, using a t-distribution calculator, for a two-tailed 98% confidence interval, with 12 - 1 = 11 df, is t = 2.7181.

As for the other parameters, they are given by:

[tex]\overline{x} = 4348.8, s = 388.2, n = 12[/tex]

Hence:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 4348.8 - 2.7181\frac{388.2}{\sqrt{12}} = 4044.2[/tex]

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 4348.8 + 2.7181\frac{388.2}{\sqrt{12}} = 4653.4[/tex]

The confidence interval estimate is (4044.2, 4653.4).

Vertex of function f(x)

From inspection of the graph, the vertex of f(x) is (2, 1)

Vertex of function g(x)

Given:  [tex]g(x)=2x^2-8x+1[/tex]

Standard form of a parabola is [tex]y=ax^2+bx+c[/tex]

Vertex form of a parabola is [tex]y=a(x-h)^2+k[/tex]
(where (h, k) is the vertex)

To convert from standard to vertex form, complete the square.

Set the equation to zero:

[tex]\implies 2x^2-8x+1=0[/tex]

Add 7 to both sides:

[tex]\implies 2x^2-8x+8=7[/tex]

Factor out common term 2 on left side:

[tex]\implies 2(x^2-4x+4)=7[/tex]

Factor expression inside brackets:

[tex]\implies 2(x-2)^2=7[/tex]

Subtract 7 from both sides:

[tex]\implies 2(x-2)^2-7=0[/tex]

Therefore:

[tex]g(x)=2(x-2)^2-7[/tex]

So the vertex of g(x) is (2, -7)

Solution

y-value of the vertex of f(x) = 1

y-value of the vertex of g(x) = -7

y-value of vertex of f(x) subtracted from the y-value of the vertex of g(x):

-7 - 1 = -8

What is the y-intercept of 2x+5y=−20 ?

(0,−4)

(10,4)

(0,10)

(−4,0)

Answers

Okay so for this problem you want to change it to an slope-intercept equation (y=mx+b, where m=slope and b=y intercept). so first you want to subtract 2x from both sides to isolate 5y, which gives you 5y=-2x-20. After that you want to isolate y so you’ll divide both sides by 5. This gives you y=-2/5(x) - 4. because b is the y-intercept and -4=b, then the y-intercept is -4. from here you need to know that coordinates are listed as (x, y) so the y-intercept is where x is equal to 0. So the answer is (0,-4). Does that make sense?

Solve the compound inequality: 3x+1<-5 or 2x-5>7

Answers

Answer:

[tex]\frac{x-3w}{2}[/tex] = t

x < -2

Step-by-step explanation:

For the first equation, let's solve for t.

Subtract 3w from both sides of the equation.

x - 3w = 2t

Now divide by 2.

[tex]\frac{x-3w}{2}[/tex] = t

t is equal to [tex]\frac{x-3w}{2}[/tex].

For the first inequality, let's solve for x.

First, subtract 1 from both sides, then divide by 3. The result is:

x < -2.

For the second inequality:

First add 5 to both sides, then divide by 2. The result is:

x > 6.

Compare the distances traveled by the hockey pucks before hitting the ground.

Answers

Answer:

x₁ > x₂

Step-by-step explanation:

Both actions imply a parable trajectories, since both are projectile shot cases.

Let´s call x₁ maximum distance in the first case

The maximum height is just in the middle of the curve, therefore x₁ the maximum horizontal distance is equal to 60 feet.

In the second case, the parable curve is modeled by:

y = x₂*( 0.08 - 0.002x₂)    or  y = 0.08*x₂ - 0.002*x₂²

A second degree equation, solving for x₂ and dismissing the value x₂ = 0

we get:

y = 0       ⇒    x₂*( 0.08 - 0.002x₂) = 0    x₂ = 0

And 0,08 - 0.002*x₂ = 0

- 0.002*x₂ = - 0.08

x₂ = 0.08/0.002

x₂ = 40 f

Then  x₁ > x₂

Gerald is going mini golfing at Golf-O-Rama with his family. For his family of 5 to play it costs $34. They were charged for three student tickets and two adult tickets. If a student ticket costs 3/4 as much as an adult ticket costs, how much does one student ticket cost?

Answers

Answer:

The cost of one student ticket = $6

Step-by-step explanation:

They were charged for three student tickets and two adult tickets.

Let the cost of one student ticket = a

Let the cost of one Adult ticket = b

If a student ticket costs 3/4 as much as an adult ticket costs

a = 3/4(b)

= 3b/4

For his family of 5 to play it costs $34.

Hence:

3a + 2b = $34

a = 3b/4

3(3b/4) + 2b= 34

9b/4+ 2b = 34

9b + 8b / 4 = 34

17b/4 = 34

17b = 34 × 4

b = 136/17

b = $8

The cost of one Adult ticket = $8

Note that:

a = 3b/4

a = 3(8)/4

a = 24/4

a = $6

Therefore, the cost of one student ticket = $6
