c=36+g

c:g:s=5:2:1

The ratio gives us two equations so that's three equations in three unknowns.  Actually we're after the total t; let's put that in to solve for directly.

c:g:s:t = 5 : 2 : 1 : 5+2+1

We turn the ratio to fraction equations.  s has the one; let's write everything in terms of s.

c/s = 5/1,  g/s = 2/1, t/s = 8/1

Clearing the fractions,

c = 5s, g = 2s, t = 8s

Our other equation is

c = 36 + g

Substituting in for c and g,

5s = 36 + 2s

Solving,

3s = 36

s = 12

That's right; let's just get the total t.

t = 8s = 72

Answer: 72

Answer:

About 25.13

Step-by-step explanation:

circumference equation: 2pi(r)

2pi(4) = 25.13

Answer:

To find out the range, you check the minimum and maximum of the graph, and then check the y-component of these minimum and maximum.

You would get the minimum(-6, -6), and maximum(3, 4), get the y-component of these two points, you got the range: -6 to 4

Hope this helps!

Answer:

You can substitute the x value of coordinate (x,y) in the equation. If the outcome = the y value in the coordinate (x,y), then you have determined it to be on the system of linear equations.

Step-by-step explanation:

Point P has a coordinates: ( Px , Py ).

You can choose which value is easy to substitute. Eighter start with the Py or you could start with the Px. It could save you time if you pick the right one for the job.

If you want to verify if any point is valid in any (linear) equation(s), you can:

a) substitute the x value of coordinate (x,y) in the equation, and if the outcome has the same value as y in the coordinate (x,y), then that point is a valid solution of the (linear) equation.

b) substitute the y value of coordinate (x,y) in the equation, and if the outcome has the same value as x in the coordinate (x,y), then that point is a valid solution of the (linear) equation.

Answer:

You can substitute the x value into the equation if the answer for y is the same for the y coordinate you will have your answer.

The area of the shaded portion of the circle is [tex]\frac{29\pi}{3} \ mm^{2}[/tex]. The correct option is b) 29 π mm² got to station 3

From the question, we are to determine the area of the shaded portion.

The shaded portion in the circle is the major sector.

The area of a sector is given by the formula,

[tex]A = \frac{\theta}{360 ^\circ} \times 2\pi r[/tex]

Where [tex]\theta[/tex] is the angle subtended by the sector

and r is the radius of the circle.

From the given information,

r = 6 mm

and [tex]\theta[/tex] is the angle subtended by the major sector

Therefore

[tex]\theta = 360^\circ - 70^\circ[/tex]

[tex]\theta = 290^\circ[/tex]

Putting the parameters into the formula, we get

[tex]A = \frac{290^\circ}{360 ^\circ} \times 2\pi \times 6[/tex]

Simplifying

[tex]A = \frac{29}{3} \tim\pi \ mm^{2}[/tex]

Hence, the area of the shaded portion of the circle is [tex]\frac{29\pi}{3} \ mm^{2}[/tex]. The correct option is b) 29 π mm² got to station 3

Answer:

12 inches

Step-by-step explanation:

I just took the unit test review on edge

Since the minor arc AB measures 9π inches, the length of the radius of circle C is equal to: B. 12 inches.

Given the following data:

Mathematically, the length of an arc formed by a circle is calculated by using this formula:

Arc length = rθ

Where:

Substituting the given parameters into the formula, we have:

9π = r × 3π/4

36π = 3πr

36 = 3r

r = 36/3

Radius, r = 12 inches.

y = 1/2 x -3

Explanation: the y-intercept is where it crosses the y axis so the y-intercept is -3

Answer:

3/12 or 1/4

Step-by-step explanation:

To find what is between, we have to use the formula:

x + y= z

z/2 = midpoint!

So, we can do that with this number.

1/6 + 2/6 = 3/6. We could simplify it, but let’s keep it at 3/6

3/6 divided by 2 = 3/6 · 1/2 = 3/12

So, the midpoint would be 3/12.

x = 12

Step-by-step explanation:

2x+3=x+15   (subtract x from both sides)

2x + 3 - x = x + 15 - x

x + 3  = 15 (subtract 3 from both sides)

x + 3 - 3 = 15 - 3

x = 15-3

x = 12

Answer:

I believe it is Kadeem who takes longer by 10 minutes.

Step-by-step explanation:

A person whose speed is slow will take longer to reach so Kadeem takes longer by 0.5 hours.

Given that,
Kadeem and Quinn both drive 25 miles.
Kadeem drives at a constant speed of 50 miles an hour.
Quinn drives at a constant speed of 75 miles an hour.
To determine who takes longer to drive the 25 miles.

Distance is defined as the object traveling at a particular speed in time from one point to another.

Here,
Time is taken by Kadeem to reach 25 miles with a speed of 25 miles per hour
= 25 / 50 = 0.5 hour

Time is taken by Quinn to reach 25 miles with a speed of 75 miles per hour,
= 25 / 75 = 0.34 hour

Thus, a person whose speed is slow will take longer to reach so Kadeem takes longer by 0.5 hours.

Answer: 35 chocolates were bought and 52 gums were bought.

Step-by-step explanation:

c + g = 87    where c is the number of chocolate and g is the number og gums

1.50c + 0.50g = 78.50    solve both equations by elimination.

-1.50c - 1.50g =  -130.5

1.50   + 0.50g = 78.50

           -1g =  -52

             g= 52

1.50c + 0.50(52) = 78.50

 1.50c + 26 = 78.50

             -26     -26

1.50c = 52.5

c = 35

Step-by-step explanation:

Length of the track = 121/4 kilometers

Length is used to measure the distance between two points. Length is the longest dimension of a figure and it shows how long the given object or figure is. It is expressed in linear units like meters, centimeters, inches, and so on.

Given,

swimming course length = 5/4 kilometers

Bike track length = 95/4 kilometers

Running track length = 21/4 kilometers

Total length of the course = 5/4 + 95/4 + 21/4

                                            = (5 + 95 + 21)/4

                                            = (100 + 21)/4

                                            = 121/4 kilometers

Hence, 121/4 kilometers is the length of the course.
