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.
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.

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

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?
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
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.
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.

a line that passes through (4,5) and (0, -12)
Answer:
Step-by-step explanation:
Hello : let A(4,5) B(0,-12)
the slope is : (YB - YA)/(XB -XA)
(-12-5)/(0-4) = 17/4
an equation is : y=ax+b a is a slope
y = (17/4)x +b
the line through point B(0,-12) : -12 = (17/4)(0)+b
b =-12
the equation is : y =(17/4)x-12
What value of x makes this equation true?
12x - 15 = 6 - 3x

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.
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

Solving the following system using the elimination of substitution method.
5a+3b=11
-2a+3=b
Answer:
a = -2
b = 7
Step-by-step explanation:
5a+3b=11
-2a+3=b
substitute for b:
5a + 3(-2a + 3) = 11
5a -6a + 9 = 11
-a = 2
a = -2
b = 7

If I went to the store in a boat on a boat how cold was it true or false.
Answer:
Any temp less than 70 degrees is dangerous. So really, probably the worst thing about cold weather boating is the danger if you fall in. If it's really cold and you are bundled up, you don't have as much flexibility. If you have gloves on, you can't get the same grip.

An item is regularly priced at $60. It is on sale for 55% off the regular price. What is the sale price?
Answer: Your paying 27 dollars. Your saving 33 dollars.
Step-by-step explanation: I used a calculator :)
Answer:
$27
Step-by-step explanation:
To find the percent of a number, we can use the formula Px = y.
In this formula, P is the percent we are finding. x and y are the numbers we are given, x being the number we are finding a percentage of and y being the answer.
To substitute a percent into the formula, we have to first convert it into a decimal. Simply remove the % sign and move the decimal point two places to the left. We have 0.55.
Now we can plug in our values.
0.55 · 60 = y
0.55 · 60 = 33
55% of 60 is 33.
The question asks for the price of the item when 55% is taken off of the original price.
So, we have to subtract 33 from 60.
60 - 33 = 27
The sale price, then, is $27.
I hope this helps ^^
Good luck :)
5. If the dimensions of a rectangle are doubled, which of the following best describes an effect on the rectangle?
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.

O A. (2,50)
O B. (-2, 10)
C. (-2, 50)
O D. (2,150)
Answer:
B(-2, 10)
Step-by-step explanation:
-10x+30=25x+100
subtract 25 from -10 (make it -25)
-35x+30=100
subtract 30 from 100 (make it -30)
-35x=70
divide by -35
x=-2
Plug it in:
-10(-2)+30
-20+30

An island is inhabited by two types of people: truth-tellers and liars. The truth-tellers always speak the truth and the liars always lie. 25 of the island's inhabitants stood in a line. Each of them with the exception of the first person said: The person directly in front of me is a liar, while the person standing first in the line said: Everyone standing behind me is a liar. How many liars stood in the line?
Answer:
Truth teller
Step-by-step explanation:
Arnie is most likely to be a liar in this case.
The response should satisfy the conditions in the statement.
The question is based on the logic. The guiding word is the conditional "if."
Logically, people at the island are either truth tellers or liars; it follows that Arnie is a truth teller and is an inhabitant of the island.
It is notable that each of them has some probability of being a truth-teller or a liar at some point.
