1 Tanya is training a turtle for a turtle race. For every 1/6 of an hour that the turtle is crawling, he can travel 1/23 of a mile. At what unit rate is the turtle crawling?​

Answer:

Step-by-step explanation:

6x + 9 = 8 - 4.4x                Add 4.4x to both sides

6x+4.4x+ 9 = 8                  Combine

10.4x + 9 = 8                      Subtract 9 from both sides

10.4x = 8 -       9                 Combine

10.4x = - 1                            Divide by 10.4

x = - 1 / 10.4

Answer x = -0.09615 or rounded x = - 0.1

Florida has the highest population while Montana has the smallest population.

The statements that are true are;

The table in the question is presented as follows;

[tex]\rm Population \ density=\dfrac{Total \ population \ of \ the \ area}{Total \ area}[/tex]

By rounding down to the next whole number, we have

Population density of Florida is; 19,317,568 ÷ 53,927 mi² ≈ 358 per mi²

The population density of Hawaii is; 1,392,313 ÷ 6,423 mi² ≈ 216 per mi²

Population density of Montana is; 1,005,141 ÷ 145,552 mi² ≈ 6 per mi²

Population density of Oregon is; 3,899,353 ÷ 95,997 ≈ 40 per mi²

Therefore;

The population density for Montana can be found using the ratio of 1,005,141:145,552.

The population density of Florida (approximately 358 per mi.²) is greater than the population density of Hawaii (approximately 216 per mi²).

Montana is the state with the smallest population density with approximately 6 persons per square mile.

The true statements are;

The population density for Montana can be found using the ratio of 1,005,141:145,552.

The state with the smallest population density is Montana.

Answer: 645

Step-by-step explanation: 645 rounded to the nearest 10 is 650. Anything below 645 doesn't round to 650. With the five in the ones place, 645 is the smallest possible number that can be rounded to 650.

Answer:

v = 18.38

Step-by-step explanation:

We are going to use the Pythagorean theorem

We see that there are double slits on the right side of the triangle, indicating that 5.22 applies to the other double slits, making it 5.22.

Now we put that in the equation of [tex]b=\sqrt{c^2-a^2}[/tex]

[tex]b = \sqrt{19.11^2+5.22^2}[/tex]

[tex]b = \sqrt{365.1921-27.2484}[/tex]

[tex]b = \sqrt{337.9437}[/tex]

[tex]b = 18.3832450889[/tex]

Rounded

v = 18.38

Answer:

7. parallel:  k = 3

   perpendicular:  k = -4/3

8. $1300

Step-by-step explanation:

7.

Rewrite each equation as the slope-intercept form of a linear equation:

y = mx + b (where m is the slope and b is the y-intercept)

  8y = 12x + 6

⇒ [tex]y=\dfrac32x+\dfrac34[/tex]

   4y = k(2x + 10)

⇒ 4y = 2kx + 10k

⇒ [tex]y = \dfrac12kx + \dfrac52k[/tex]

If the graphs are parallel their slopes will be the same.

[tex]\implies \dfrac32=\dfrac12k[/tex]

[tex]\implies k=3[/tex]

If the graphs are perpendicular then the product of their slopes will be -1.

[tex]\implies \dfrac32 \times \dfrac12k=-1[/tex]

[tex]\implies \dfrac12k=-\dfrac23[/tex]

[tex]\implies k=-\dfrac43[/tex]

8. Create a linear equation, where x is the number of coffee mugs and y is the total cost (in dollars).

Choose 2 ordered pairs from the table:  (10, 110) and (20, 195)

Let [tex](x_1,y_1)[/tex] = (10, 110)

Let [tex](x_2,y_2)[/tex] = (20, 195)

Use the slope formula to find the slope m:

[tex]\implies m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{195-110}{20-10}=\dfrac{17}{2}[/tex]

Now use the point-slope form of linear equation:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-110=\dfrac{17}{2}(x-10)[/tex]

[tex]\implies y=\dfrac{17}{2}x+25[/tex]

Substitute x = 150 into the equation and solve for y:

[tex]\implies y=\dfrac{17}{2}(150)+25=1300[/tex]

Therefore, the total cost of ordereing 150 mugs is $1300

Answer:

[tex]\dfrac{7}{12}[/tex]

Step-by-step explanation:

Method 1

convert the fractions so that their denominators are 12:

[tex]\dfrac12=\dfrac{1 \times 6}{2 \times 6}=\dfrac{6}{12}[/tex]

[tex]\dfrac23=\dfrac{2\times4}{3\times4}=\dfrac{8}{12}[/tex]

From inspection, we can determine that the fraction that lies exactly halfway between [tex]\dfrac{6}{12}[/tex] and [tex]\dfrac{8}{12}[/tex] is [tex]\dfrac{7}{12}[/tex]

Method 2

Find the difference between the fractions and divide by 2:

[tex]\dfrac{\dfrac23-\dfrac12}{2}=\dfrac{1}{12}[/tex]

Add this to the smallest fraction (1/2):

[tex]\dfrac12+\dfrac{1}{12}=\dfrac{7}{12}[/tex]

Answer:

[tex]sin(G)=0.91[/tex]

Step-by-step explanation:

Recall that [tex]sin(\theta)=\frac{opposite}{hypotenuse}[/tex] with respect to the angle [tex]\theta[/tex] for a right triangle. Since we are given our hypotenuse of [tex]\sqrt{85}[/tex] and our adjacent side of [tex]\sqrt{15}[/tex], we can use the Pythagorean Theorem to solve for the missing opposite side:

[tex]a^2+b^2=c^2\\\\(opposite)^2+(adjacent)^2=(hypotenuse)^2\\\\(opposite)^2+(\sqrt{15})^2=(\sqrt{85})^2\\\\(opposite)^2+15=85\\\\(opposite)^2=70\\\\opposite=\sqrt{70}[/tex]

Thus, [tex]sin(G)=\frac{\sqrt{70}}{\sqrt{85}}\approx0.91[/tex]

Answer:

can u give the prices for the tickets?

An adult ticket costs $2 more than a child ticket

Let x and (x + $2)represent the cost of the child and adult ticket respectively

2(x+ $2) + 3x = $34

now solving for x

2x+ $4 + 3x = $34

5x = $30

 x = $6 , the cost of the child ticket.

the cost of adult ticket $6+2=$8

Step-by-step explanation:

Let's take 1,400 is to be seperated between A and B

Amount of money A will get = 1400* 7/10= 980

Amount of money B will get = 1400* 3/10= 420

Checking the answer:

980+420 = 1,400

Hence, 1,400 will be shared by ratio 7:3 is 980 and 420.

[tex]y=\frac{1}{2}[/tex]

Step-by-step explanation:

We can solve this system using elimination.

In this case, we can eliminate y by subtracting both equations...

[tex]3x-2x-4y-(-4y)=10-6\\x-4y+4y=10-6\\x=4[/tex]

Then, substitute 4 for x to solve for y...

[tex]3x-4y=10\\3(4)-4y=10\\12-4y=10\\\text{Subtract 12 from both sides}\\-4y=-2\\\text{Divide both sides by -4}\\y=\frac{1}{2}[/tex]

Answer:

y=1/2

The values of [tex]\theta[/tex] for different conditions were calculated with the help of trigonometric functions.

The solution of trigonometric functions is the values of angles where the function value becomes zero.

Given function is:

A)[tex]f(\theta ) = 2Sin\theta +\sqrt{3}[/tex]

[tex]f(\theta ) = 2Sin\theta +\sqrt{3} = 0\\2Sin\theta = -\sqrt{3} \\Sin\theta =-\frac{\sqrt{3} }{2}[/tex]

[tex]\theta =n\pi +\frac{\pi }{3}[/tex] where n=1,3,5,7......

So, at [tex]\theta =n\pi +\frac{\pi }{3}[/tex]  pogo stick's spring will be equal to its non-compressed length.

B)If the angle was doubled, the function will look like this,

[tex]f(\theta ) = 2Sin2\theta +\sqrt{3}[/tex]

[tex]f(\theta ) = 2Sin2\theta +\sqrt{3} =0[/tex]

[tex]2Sin2\theta +\sqrt{3} = 0\\2Sin2\theta = -\sqrt{3} \\Sin2\theta =-\frac{\sqrt{3} }{2}[/tex]

[tex]2\theta =n\pi +\frac{\pi }{3}\\\theta = \frac{n\pi }{2} +\frac{\pi }{6}[/tex]where  n=1,3,5,7....

if n=1, [tex]\theta =\frac{2\pi }{3}[/tex]

n=2, [tex]\theta =\frac{7\pi }{6}[/tex]

n=3, [tex]\theta =\frac{5\pi }{3}[/tex]

So,  [tex]\theta =\frac{2\pi }{3}, \frac{7\pi }{6} ,\frac{5\pi }{3}[/tex] will be solution in [0,2π}.

C)[tex]g(\theta) =1-cos^{2} \theta +\sqrt{3}[/tex]

[tex]g(\theta) =Sin^{2} \theta + \sqrt{3}[/tex]

[tex]g(\theta) =f(\theta)[/tex]

[tex]sin^{2} \theta +\sqrt{3} = 2Sin\theta+\sqrt{3}[/tex]

[tex]Sin^2\theta = 2Sin\theta[/tex]

[tex]Sin^2\theta-2Sin\theta = 0\\Sin\theta(Sin\theta-2) =0\\Sin\theta =2(NotPOSSIBLE)\\Sin\theta =0[/tex]

[tex]\theta=n\pi[/tex] where n=1,2,3.....

So, [tex]\theta=n\pi[/tex], the lengths of springs from the original pogo stick and the toddler's pogo stick are equal.

Hence, the values of [tex]\theta[/tex] for different conditions were calculated with the help of trigonometric functions.
