Help w/ math, please & thanks!

Answer:

A.

Step-by-step explanation:

If we assume that the population of the town is proportional to the random people selected to take the survey, then we can say that the answer is A, People at least 50 years old are the largest age group in town. Since the survey is random and the percentage of the 50-year old population group is higher when individually compared to the other groups, we can assume that the town's population consists of a high number of people who are 50-years old or older.

And although it is not a given answer choice, it would actually make more sense to say that out of the number of people that took the survey, those who were 50 years old or older consisted of the largest age group.

Step-by-step explanation:

Answer:

Metric units of measurement differ by powers of 10 - 10, 100, 1,000, and so on. Thus, converting from one metric unit to another is always accomplished by multiplying or dividing your initial measurement by the appropriate power of ten.

A linear equation should have points that graph in a straight line.

Step-by-step explanation:

I hope it help !

A linear equation should have points that graph in a straight line.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

A linear function is a function in which the slope remains constant.

Since a straight line has a constant slope thus it will represent the straight line.

Hence "A linear equation should have points that graph in a straight line".

Answer:

46 rides; the constant is the $12 turkey leg

Step-by-step explanation:

To solve this, you can write an equation:

c = .5r + 12

where c is cost and r is rides (the constant is 12 because it doesn't change)

You already know that the cost is 35, so you just need to plug it in and solve:

c = .5r + 12; c = 35

35 = .5r + 12

23 = .5r

r = 46

So, on $35 and an expense of $12, Ashley can ride 46 rides.

Answer:

Ashley can go on 46 rides

Step-by-step explanation:

12+0.50x=35

-12               -12

0.50x=23

0.50x/0.50= 23/0.50

 x=46              

Answer:

Answer:

Radius is the distance from the center outwards

Diameter goes straight across the circle, through the center.

Step-by-step explanation:

Hope this Helps!!

let me know if it doesn't

Answer:

Step-by-step explanation:

Diameter is the longest line that you can draw in a circle passing through the centre of the circle.

Radius is the line joining the centre of the circle to any point on the circumference.

Explanation:

Diameter is the ratio of the circumference of the circle to the irrational constant 'pi' (3.1415...). Radius is the half of the diameter.

D=2x radius  and radius =D/2

Actually pi is defined to be the ratio of the circumference of the circle to the diameter of the circle. Therefore, you can solve for the diameter from that equation.

π=C/D   , D=C/π  Or , C=π x D

Answer:

For the first one

x= About 32.02

y= About 27.58

z= About 55.16

For the second one

x= 6

y= 12

z= about 16.97

Step-by-step explanation:

Their all really simple

These are special right triangles, a 45, 45, 90 and a 30, 60, 90 triangle. The formla for these triangles are shown in the picture below.

Now for the first one ]

Lets find Z first

Now this is a 45 special right triangle so we know the other side s 39 but the hypotenuse is n[tex]\sqrt{2}[/tex] (I’m using N becuase x and y is taken) So n is basically 39 (look at the image below) and just solve that. Now for x and y. We know its a 30, special right triangle. We know that 39 here is already the answer for  N[tex]\sqrt{3}[/tex] so make an equation to find the n and you’ll get 27.58 for y. Now For x, its just doubled the y.

For the second one this is easier

We know that the x is (6) becuase its already in the radical number, now to find the hypotnuse, we double that and get 12. Now we know what y is becuase since the 2nd triangle is a 45/45/90, we know that 12 is y, the hypotnuse is just N[tex]\sqrt{2}[/tex] and we just plug in the n with 12 and solve it!

Answer:

4 tickets for $1

Step-by-step explanation:

I just divided 8 with 2.00 and got 4.

The value of the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased is 1/4.

It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.

It is given that:

At a school carnival, tickets can be purchased to participate in different activities.

The data are shown in the picture.

From the data:

y ∝ x

Removing the proportional sign:

y = kx

Plug x = 8

y = 2

2 = 8k

k = 1/4

Thus, the value of the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased is 1/4.

Step-by-step explanation:

The age of Mary and the age of Beth will be 10 years and 4 years, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Three times Mary’s age added to Beth’s age is 34 years. Half of Mary’s age minus Beth’s age is 1 year.

Let 'x' be the age of Mary and 'y' be the age of Beth. Then the equations are given below.

3x + y = 34        ...1

x/2 - y = 1          ...2

From equations 1 and 2, then we have

3(2y + 2) + y = 34

6y + 6 + y = 34

7y = 34 - 6

7y = 28

y = 4

Then the value of the variable 'x' is given as,

3x + 4 = 34

3x = 30

x = 10

The age of Mary and the age of Beth will be 10 years and 4 years, respectively.

Step-by-step explanation:

The five fractions that provide a range of values between 1/2 and 7/8 are 5/8, 3/4, 11/16, 2/3, and 13/16.

Here are five fractions that lie between 1/2 and 7/8:

5/8: This fraction is greater than 1/2 but less than 7/8. It can be obtained by dividing 5 by 8.

3/4: This fraction is greater than 1/2 and closer to 7/8. It is obtained by dividing 3 by 4.

11/16: This fraction is closer to 1/2 and slightly less than 7/8. It can be obtained by dividing 11 by 16.

2/3: This fraction is greater than 1/2 and closer to 7/8. It is obtained by dividing 2 by 3.

13/16: This fraction is closer to 7/8 and greater than 1/2. It can be obtained by dividing 13 by 16.

These five fractions provide a range of values between 1/2 and 7/8. They demonstrate different proportions and can be used in various contexts where a fraction between 1/2 and 7/8 is required, such as measurement, comparison, or estimation.
