Answer:
A Kite Ahe guessedStep-by-step explanation:
For a quadrilateral in which the diagonals cross at right angles, such as a rhombus or kite, the area can be found as half the product of the diagonals.
For the purpose here, we can ignore the factor of 1/2, which is the same for both, and simply consider the products of the diagonals.
Kite A has an area proportional to (30 in)(30 in) = 900 in².
Kite B has an area proportional to (20 in)(40 in) = 800 in².
Kite A has a larger area, so will use more paper.
__
Only Rudy knows why he chose answer C. Perhaps he guessed, rather than doing any math.
Answer:
A. Kite A
Step-by-step explanation:
To determine which of the two kites will use need more paper to make, find the area of each kite.
Kite A:
Area = (d1*d2)/2
d1 = 30 in.
d2 = 30 in.
Area of kite A = (30*30)/2 = 450 in.²
Kite B:
Area = (d1*d2)/2
d1 = 20 in.
d2 = 40 in.
Area of kite B = (20*40)/2 = 400 in.²
✅Kite A will use more paper to make because it has a greater area of 450 in.² than Kite B (400 in.²).
So, Ruby was wrong. He most likely didn't calculate the area of both kites correctly.

The graph of a function f is shown below.
Find f(0).
Answers
Answer: f(0)=-1
Step-by-step explanation:
f(0) is a fancy way of saying the y value of the equation. the f(0) means that x=0. If you look at x=0, the graph is at y=-1. Therefore, f(0)=-1.
Answer:
7, f(0) would have to be lower than the semi-circle shown below, and therefore because the line passes through -3 and -4, its |-7|, which is 7.

What are steps that you should take to determine if Matilda bought the correct amount of border? Select all that apply.
Answers
The steps that Matilda should take to determine if she bought the correct amount of border are:
Convert yard to feetCalculate the number of feet of border she boughtCompare the number of feet of border Maltida bought to the the perimeter of the room. Did Maltida buy the correct amount of border?The first step is to convert inches to feet
1 inch = 1/12 feet
96 / 12 = 8 feet
The second step is to convert yards to feet
1 yard = 3 feet
3 x 3 = 9 feet
Now, determine the perimeter of the room: 9 + 9 + 8 + 8 = 34 inches
The fourth step is to determine the feet of border bought: $30 / $1 = 30
34 > 30 thus the border is not enough

How much must be deposited today into the following account in order to have get 35,000 in 5 Years
An account with monthly compounding and an APR of 4%
should be deposited today.
(Do not round until the final answer. Then round to the nearest cent as needed)
Answers
Answer:
$ 28,665.11 must be deposited today into the account.
Step-by-step explanation:
Given that there is an account with monthly compounding and an APR of 4%, to determine how much must be deposited today into the following account in order to have $ 35,000 in 5 years, the following calculation must be performed:
X x (1 + 4/12) ^ 5x12 = 35,000
X x (1 + 0.333) ^ 60 = 35,000
X x (1,333) ^ 60 = 35,000
X x 1.220999 = 35,000
X = 35,000 / 1.22099
X = 28,665.11
Thus, $ 28,665.11 must be deposited today into the account.

What is the area of the figure?
Answers
Answer:
25 1/5
Step-by-step explanation:
First, do 7 1/4 times 6. This gets you to 43.5
Next, take the area of the space that is not there. 5 times 3 2/3 is 18.33333, round to 18.3. (If this is not rounded, the fraction may be slightly different).
Now, subtract 18.3 from 43.5 to get 25.2, since 18.3 space does not exist.
25.2 as a fraction is 25 1/5

Which set of rational numbers are orders from least to greatest? A) -1, -1 1/2, -1 1/4, -1 7/8 B)-1 7/8, -1 1/2, -1 1/4, -1
C) -1, -1 1/4, -1 1/2, -1 7/8 D) -1 7/8, -1 1/4, -1 1/2, -1
Answers
Answer:
-1 7/8, -1 1/2, -1 1/4, -1
Step-by-step explanation:
First note that the negative value closer to zero on the number is greater. an those far from zero will be the least
According to the given option, we can first express the fractions as percentage as shown
-1 7/8 = -15/8 * 100 = -187.5%
-1 1/2 = -3/2 * 100 = -150%
-1 1/4 = -5/4 * 100 = -125%
-1 = -1 * 100 = -100%
Based on the explanation above, the least value is -187.5% and the greatest value is -100%
Rearranging from least to greatest is expressed as -187.5%,-150%, -125%, -100%
According to their respective fractions;
-1 7/8, -1 1/2, -1 1/4, -1
