The equation for the line of best fit is y=2x+2.5. Soon, Edmond is going to a new fair. Use the equation for the line of best fit to predict how many tickets he could purchase for $12.50.

Answers

Answer:

x = 5

Step-by-step explanation:

The equation of a line is given by :

y=2x+2.5

Where

y is cost and x is number of tickets

Put y = $12.5 in the above equation

So,

12.5=2x+2.5

10 = 2x

x = 5

So, he can purchase 5 tickets.

Vanessa has $200 in her savings account and
just received $30 for her birthday. She intends
to spend all of her money on coffee. She spends
$3.50 on coffee every day. Write an equation
that can be used to find the amount of money she
has left after x days.

Answers

Answer:

y = -3.5x + 230

Step-by-step explanation:

Find how much money she has now:

200 + 30 = $230

To create an equation to find how much money she has left, let y represent the amount of money left, and x represent the number of days.

Coffee will cost $3.50 every day, so 3.5x will represent all of the money that she will spend on coffee.

The amount of money she has left will be represented by 230 - 3.5x.

Rearrange this to put x in front, and let this equal to y to create the equation:

y = -3.5x + 230

So, the equation that can be used to find how much money she has left is y = -3.5x + 230

13.At the Finch School bake sale, donuts sell
for $2 each muffins sell for $3 each. A
combined total of 104 donuts and muffins
are sold, resulting in $243 in sales. Which
of the following statements must be true?
a. 69 more muffins were sold than donuts.
b. 34 more muffins were sold than donuts.
c. 34 more donuts were sold than muffins.
d. 69 more donuts were sold than muffins.

Answers

Answer:

c)

Step-by-step explanation:

create a system of equations:

d + m = 104

2d + 3m = 243

now use substitution method based on 'd = 104 - m'

2(104 - m) + 3m = 243

208 - 2m + 3m = 243

208 + m = 243

m = 35

So, 35 muffins and 69 donuts were sold.

This is 34 more donuts than muffins.

Meteor Crater, located near Flagstaff, Arizona, is a circular
crater with a circumference of 2.32 miles. What is the
approximate diameter of the crater?

Answers

Answer:

The approximate diameter of the crater is 0.74 mile.

Step-by-step explanation:

Circumference of a circle(C)=2*π*r(radius of the circle)

2.32 miles=2π*r

or, r=2.32 miles/2π

So, r=0.369 mile

Then,

d=2r

d=2*0.369 mile

So, d= 0.74 mile

A box contains 512 grams of cereal. one serving is 56 grams. how many servings of cereal dose the box contain?​ GETS BRAINLIEST

Answers

Answer:

the answer is 9.14 so that means about nine servings of cereal

Step-by-step explanation:

you you divide 512 and 56 and you get a total of 9.14

A box contains 512 grams of cereal.

one serving of cereal = 56

So, The number of servings of cereal contained in the box can be calculated by dividing the total of grams over one serving of cereal

∴ The number of servings = 512/56 and all the calculations done correctly would be the right answer

So, The correct answer is 9 8/56. Hope this helps!

What is the value of x in the diagram of Circle O below? *

Answers

Answer:

60 degrees

Step-by-step explanation:

As we know that a circle is 360 degrees, and as line AB bisects the circle, then the resulting "semi-circle" is 180 degrees. As we know that angle AC is 120 degrees, it's simple subtraction, to find that 180-120 is 60. Therefore, the value of x must be 60 degrees.

Hope this explanation helped!

5. If the dimensions of a rectangle are doubled, which of the following best describes an effect on the rectangle?​

Answers

Answer:

Since length and width are perpendicular, Doubling either one will double the area. So Doubling both will quadruple the area. 2x2 = 4.

This idea works if the dimensions doubled are those that are used to compute area. Like the base and height of a triangle.

More generally, in a polygon, if all the sides are doubled, the area is multiplied by 4. In a circle, Doubling the radius will quadruple the area.

In 3 dimensions, Doubling one dimension will double the VOLUME. Doubling two perpendicular dimensions will quadruple the volume and Doubling 3 perpendicular dimensions will multiply the volume by 2x2x2 or 8.
