The formula used for this is a^2+b^2=c^2, I don't really get this problem.
Answer:
127.3
Step-by-step explanation:
The formula you gave is is known as the Pythagorean Theorem.
It is used to find the hypotenuse (longest side) of a right triangle with the lengths of the other two legs (sides).
Here, a is the hypotenuse of two adjacent triangles. Both triangles are right triangles, and have legs (not including the hypotenuse) of 90 ft.
Now, the formula is a^2 + b^2 = c^2.
A and b are the two shorter legs of the triangle: 90 and 90. Let's insert these values into the formula.
90^2 + 90^2 = c^2
90^2 is 8100, and 8100 plus 8100 is 16200.
16200 = c^2 (c is the hypotenuse, or a)
Now, we just have to find the square root of 16200.
sqrt16200=127.27....
When we round this to the nearest tenth, we get 127.3.
Students in band are selling oranges and grapefruit to earn money for a trip. Mrs.Whitten purchased three boxes of oranges and two boxes of grapefruit from a student for a total of $22.50. Mr. Rutig purchased one bag of oranges and four boxes of grapefruit, spending a total of $28.50. How much is one box of oranges?
Answer:
The cost of one box of oranges = $3.3
Step-by-step explanation:
Let x be cost of one box of oranges and y be the cost of one box of grapefruit.
We have been given that Mrs. Whitten purchased 3 boxes of oranges and 2 boxes of grapefruit from a student for a total of $22.50. We can represent this information as:
[tex]3x+2y=22.50...(1)[/tex]
Mr. Rutig purchased 1 box of oranges and four boxes of grapefruit, spending a total of $28.50. We can represent this information as:
[tex]x+4y=28.50...(2)[/tex]
We will solve our system of linear equations using substitution method.
From equation (1) we will get,
[tex]y=\frac{22.50-3x}{2}[/tex]
Substituting y's value in equation (2) we will get,
[tex]x+4*(\frac{22.50-3x}{2})=28.50[/tex]
[tex]x+2*(22.50-3x)=28.50[/tex]
Upon distributing 2 we will get,
[tex]x+45-6x=28.50[/tex]
[tex]x-6x=28.50-45[/tex]
[tex]-5x=-16.5[/tex]
[tex]x=\frac{-16.5}{-5}[/tex]
[tex]x=3.3[/tex]
Therefore, the cost of one box of oranges is $3.3.

Alonzo takes 12 minutes to run 6 times around a 400-meter track. Assuming he runs at a constant speed, how long does he take to run 1-kilometer?
Answer:
5 minutes to run 1 kilometer
Step-by-step explanation:
Alonzo takes 12 minutes to run 6 times around a 400-meter track.
6 times around a 400 m track
400 * 6 = 2400 meters
It take 12 minutes to run 2400 meters
2400 meters = 2400/1000 = 2.4km
distance = 2.4 km and time = 12 minutes
Now we find our constant speed
[tex]Distance = speed * time[/tex]
2.4 = speed * 12
divide by 12 on both sides
speed = 0.2
so speed is 0.2 km per minute
Now we find out time when distance = 1km
Distance = speed * time
1 = 0.2 * t
divide by 0.2 on both sides
5 = t
So it take 5 minutes to run 1 kilometer

Answer:
1) ASA 2) In explanation 3) I cant see all of the problem
Step-by-step explanation:
For Number 1 you need one more thing to prove that the triangles are congruent. You could see that there is a pair of vertical angles and vertical angles are congruent so you could use that. Angle DEA is congruent to Angle CEB. When there is a side in between two congruent angles, that is ASA.
For Number 2 it really is almost the same as number 1. First you write the given, then you write that angle DEA is congruent to angle CEB and the reason for that is that vertical angles are congruent. Lastly, you say that triangle ADE is congruent to triangle CBE.

How many of the possible outcomes have an even number or a B?
Answer:
The possible outcome could be 4 or 3
Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
There are 12 possible outcomes. Of the 12, 6 are even and 4 have B's. That would give up 10/12. But then you would subtract the possible outcomes that are BOTH even AND have a B. Only 2 possible outcomes have an even number and the letter B. So 10 minus 2 is 8. That would give you 8/12. Simplify and you will get your answer of 2/3!

State which of the following ordered pairs is a function. Set A: (-1, 0), (-2, 1), (4, 3), (3, 4) Set B: (1, 4), (2, 3), (3, 2), (4, 1) Set C: (2, 1), (3, 2), (2, 3), (1, 4) a. Set A b. Set B c. Both Set A and Set B d. Set C Please select the best answer from the choices provided
Answer:
Both set A and B.
Step-by-step explanation:
Set A: (-1, 0), (-2, 1), (4, 3), (3, 4)
Set B: (1, 4), (2, 3), (3, 2), (4, 1)
Set C: (2, 1), (3, 2), (2, 3), (1, 4)
In order for (x,y) to be a function, only one x get the value of y, but many x'es can get the value y.
Looking at the set A and B, and the definition above, we can say that they are functions.
What about set C? It is not a function, as x = 2 is equal 1 or 3, which does not meet the condition from the definition.
Final answer:
Both Set A and Set B are functions because each member of the domain in these sets maps to a unique value in the range. Set C is not a function because the same first element maps to different values in the range. Both set A and B are the answers.
Explanation:
To determine which set(s) represent a function, we need to ensure that each element of the domain maps to one and only one value in the range. By examining each set:
Set A: (-1, 0), (-2, 1), (4, 3), (3, 4): Every first element is unique, indicating a function.
Set B: (1, 4), (2, 3), (3, 2), (4, 1): Similarly, all first elements are unique, indicating a function.
Set C: (2, 1), (3, 2), (2, 3), (1, 4): The number 2 appears twice as a first element with different second elements, violating the definition of a function.
Therefore, both sets A and B represent functions since they each map every member of the domain to a unique member of the range, while set C does not.
The answer is b. Both Set A and Set B are functions.

a) 805.
b) 825.42
c) 850.85
d) 810.34
Answer:
(d) 810.34
Step-by-step explanation:
The explicit formula used for calculating the account's balance is given by:
A= P(1+R)^T
where: A= Amount (account's balance)
P= Principal (700)
R= Rate (5%)
T= Time (3 years) [since, the balance is calculated in the beginning of the forth year]

type the integer that makes the following addition sentence true
+ -6 = 1
It would be 7.
Here's why:
7 + - 6 = 1
1 = 1
It's a TRUE statement!
Hope this helps you!!!! :)
The integer value that makes the sentence true is 7, as in mathematics, adding a negative number 6 to a number, to yield 1, equates deducting 6 from that number to yield 1.
Explanation:This is a mathematics problem involving the concept of integer addition. In mathematics, adding a negative number is equivalent to subtracting that number's absolute value. Therefore, to find the integer that makes the addition sentence true, you would need to identify the number that, when subtracted by 6, equals 1.
So, the equation can be rewritten as X - 6 = 1. If you add 6 on both sides of the equation to isolate the variable X on one side, the equation becomes X = 1 + 6. As a result, it is clear that the integer value X that would make the equation + -6 = 1 true is 7.

1.) write an equation in point-slope form that represents the situation (define your variables)
2.) convert your equation to slope-intercept form
In this exercise we have to use the knowledge of equations to write the intersection equation, so we have to:
The formula for setting up an equation is given by:
[tex](y - y1) = m(x - x1)[/tex]
1.) So by the formula above, substituting for the values given in the statement, then:
[tex](y - 120) = -2(x - 7)[/tex]
2.) The equation in slope intercept form will be:
[tex](y - 120) = -2(x - 7)\\(y - 120) = -2*x + (-2*-7)\\y - 120 = -2x + 14\\y = -2x + 134[/tex]

To find the distance between two points (1,4) and (-2,3) using the distance formula, perform the relevant calculations and steps.
Explanation:To find the distance between two points using the distance formula, you can follow these steps:
Identify the coordinates of the two points. In this case, the coordinates are (1,4) and (-2,3).Plug the values of the coordinates into the distance formula: D = (√((x2 - x1)^2 + (y2 - y1)^2)).Calculate the difference between the x-coordinates and the y-coordinates separately. For this example, (x2 - x1) = (-2 - 1) = -3, and (y2 - y1) = (3 - 4) = -1.Square the differences calculated in the previous step: (-3)^2 = 9 and (-1)^2 = 1.Add the squared differences together: 9 + 1 = 10.Take the square root of the sum to find the distance: √10 ≈ 3.16.So, the distance between the points (1,4) and (-2,3) is approximately 3.16 units.

let's firstly convert the mixed fractions to improper fractions.
now, 1¼ dozen of cupcakes.... well, let's keep in mind that a dozen has 12 units, so 1¼ dozen is then 12(1¼) cupcakes total.
[tex]\bf \stackrel{mixed}{1\frac{1}{4}}\implies \cfrac{1\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{5}{4}}~\hfill \stackrel{mixed}{1\frac{2}{3}}\implies \cfrac{1\cdot 3+2}{3}\implies \stackrel{improper}{\cfrac{5}{3}} \\\\[-0.35em] \rule{34em}{0.25pt}[/tex]

In the given case, Rashida can make approximately 9 cupcakes with 1 cup of flour.
To determine how many cupcakes Rashida can make with the 1 cup of flour she has, we need to calculate the conversion factor between the given measurement of 1 2/3 cups of flour and the available 1 cup of flour.
The conversion factor is found by dividing the available amount by the required amount
(1 cup ÷ 1 2/3 cups).
We can simplify the fraction to obtain a decimal,
1 ÷ (5/3) = 3/5 ≈ 0.6.
So, Rashida can make approximately
0.6 × 1 1/4 dozen = 0.6 × 15 = 9 cupcakes.
