Construct an isosceles triangle with one 70* angle and two 4 inch sides. Is this a unique triangle? Explain why or why not.
Answers
The isosceles triangle has 2 equal sides of 4 inches and a vertex angle measure of 70 degrees, and it is a unique triangle
How to determine if the triangle is unique?The given parameters are:
Triangle type = Isosceles triangle
Side length = 4 inches
Angle measure = 70 degrees
Since the triangle is an isosceles triangle, then the equal angles would be:
Ф = 180 - 2 * 70
Ф = 40
The length (L) of the third side is:
L/2 = 7 * cos(40)
Multiply both sides by 2
L = 14 * cos(40)
L = 10.7
So, the angles in the triangle are 70 and 40 degrees; while the side lengths are 4 and 10.7 inches
See attachment for the figure of the isosceles triangle

A "box and whisker" plot is a visual representation of the 5-number summary of a data set. It shows you the minimum, maximum, median, and the 1st and 3rd quartile values.
__
The given data is sorted, so the first value (5) and the last value (19) will be the ends of the whiskers. (Eliminates choice A)
There are 15 data values, so the 8th one is the middle one, the median. That value is 10, and corresponds to the vertical line in the box. (Eliminates choices C and D.)
When the median is removed from the data set, it is divided into two parts, each containing 7 data values. The middle (4th) one of each of these are the 1st and 3rd quartiles, the ends of the box. They are 8 and 17, confirming that choice B is the correct box and whisker plot.
Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $2,260 was collected on the sale of 1,060 tickets. How many of each type of ticket were sold?
Answers
S = number of student tickets
1033 = total tickets sold
A + S = 1033
5(A) = money collected for adult tickets
S(1) = money collected for student tickets
2265 = total money collected
5(A) + S(1) = 2265
two equations and two unknowns:
5A + S = 2265
A + S = 1033
subtract 2nd equation from 1st and solve for A:
4(A) = 1232
Divide 1232 by 4 and
A = 308
Plug in value for A in 1st equation and solve for S:
A + S = 1033
308 + S = 1033
S = 725
725 student tickets and 308 adult tickets were sold

Probability (chocolate cupcakes) =
%
Note: Write your answer as a percentage rounded to the nearest whole number.
Answers
Answer: 14%
Step-by-step explanation:
The probability of a chocolate cupcake being sold would be equal to the amount of chocolate cupcakes divided by the total number of cupcakes.
= 2/(2+1+5+6)
= 2/14
= 1/7.
We convert 1/7 to a percent.
When rounded to the nearest whole percent, we get the probability as 14%.
Answer:
14%
Step-by-step explanation:
The probability of a chocolate cupcake being sold would be equal to the amount of chocolate cupcakes divided by the total number of cupcakes.
= 2/(2+1+5+6)
= 2/14
= 1/7.
We convert 1/7 to a percent.
When rounded to the nearest whole percent, we get the probability as 14%.

Annabelle and Ezra have a dog that eats 3/4 of a cup of food every morning. Annabelle lost the 1/4 cup so she used the 1/3 cup and gave him 2/3 of a cup of food. Ezra says that Annabelle did not feed the dog enough food. Annabelle says she gave him more than enough.
Who is right? Explain how they can compare the fractions to figure out who is correct.
Answers
Answer:
Ezra is correct. 2/3 = 8/12, 3/4 = 9/12. 8/12 is less than 9/12
Step-by-step explanation:
We can multiply the fractions (by multiplying both the top and bottom of a fraction, its value remains the same) by the opposite denominator. This gives us a least common denominator, so we can easily compaire the fractions.
Ezra is correct beacuse it gives us a least common denominator, so we can easily compare the fractions.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that Annabelle and Ezra have a dog that eats 3/4 of a cup of food every morning.
Also that Annabelle lost the 1/4 cup so she used the 1/3 cup and gave him 2/3 of a cup of food.
Thus We have to multiply the fractions (by multiplying both the top and bottom of a fraction, means the value remains the same) by the opposite denominator.
2/3 = 8/12,
3/4 = 9/12.
8/12 is less than 9/12
Hence, Ezra is correct beacuse it gives us a least common denominator, so we can easily compare the fractions.
