Joãozinho de Gitana calculadora o número de 12750 Qual é o número que tempo para subtrair para obter como resultado o número 12250
Responder:
500
Explicação passo a passo:
O número a subtrair de 12.750 em outro para obter 12.250
Deixe o número = x
Isso é ; se x for subtraído de 12750; nós obtemos 12250
12750 - x = 12.250
Subtraia 12750 de ambos os lados
12750 - x - 12750 = 12.250 - 12750
-x = - 500
x = 500

What is the value of x
Answer:
x = 36.03°
Step-by-step explanation:
We have to find: Angle A, also called "x
We are given: Side opposite to x and the hypotenuse of the triangle.
Trigonometric Ratio that would be used: Sin
=> Sin(x) = Opposite/Hypotenuse
=> Sin(x) = 10/17
=> x = Sin⁻¹(10/17)
=> x = 36.03 Degrees

Miko and her parents rent boats for the afternoon. Her parents rent a canoe and Miko rents a kayak. • It costs $20.49 to rent a canoe plus an additional $7.49 for each hour. • It costs $17.99 to rent a kayak plus an additional $5.99 for each hour. Miko and her parents rent one canoe and one kayak for the same amount of time, and their total cost for the rentals is $78.92. Write and solve an equation to determine the amount of time, in hours, that they rented the kayak and canoe.
Answer:
Kayak and Canoe rented for 3 hours
Step-by-step explanation:
Let the time for which they rent canoe & kayak = x hours
Total canoe cost = 20.49 + 7.49x , Total kayak cost = 17.99 + 5.99x
Given] Total canoe & kayak cost = 78.92
So, (20.49 + 7.49x) + (17.99 + 5.99x) = 78.92
20.49 + 17.99 + 7.49x + 5.99x = 78.92 ; 38.48 + 13.48x = 78.92
13.48x = 78.92 - 38.48 ; 13.48x = 40.44
x = 40.44 / 13.48 ; x = 3

Answer:
x = 9
Step-by-step explanation:
The secant- secant angle 4x° is half the difference of the intercepted arcs, that is
4x = [tex]\frac{1}{2}[/tex] (9x + 26 - 35 ) ← multiply both sides by 2 to clear the fraction
8x = 9x - 9 ( subtract 8x from both sides )
0 = x - 9 ( add 9 to both sides )
9 = x

Answer: s = 16
Step-by-step explanation:
234 = (s+2)(s-3)
s = 16, -15 (throw away -15, measurements cannot be negative)
This can be proven by substituting s for 16
234 = (16+2)(16-3)
234 = 18*13
234= 234

When factoring a trinomial into two binomials, how do you know if you are adding or subtracting the factors of the last term to get the middle term?
Answer:
Write out all the pairs of numbers which can be multiplied to produce c.
Add each pair of numbers to find a pair that produce b when added.
If b > 0, then the factored form of the trinomial is (x + d )(x + e).
Check: The binomials, when multiplied, should equal the original trinomial.
Solve for x. Round your answer to the nearest tenth.

Answer:
5.6
........................................................................
Answer:
x = 5.6
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2
4.8 ^2 + x^2 = 7.4^2
23.04 +x^2 =54.76
Subtract 23.04 from each side
x^2 = 54.76 - 23.04
x^2 =31.72
Take the square root of each side
x =5.632051136
Rounding to the nearest tenth
x = 5.6

*40 people responded that they use mouthwash.
*Of the people who use mouthwash, 30 people use floss.
*55 people responded that they do not floss.
*45 people responded that they don't floss and don't use mouthwash
Answer: The image of the completed table is shown below
In the completed table, we have the following values (left to right)
Row One: 30, 10, 40Row Two: 15, 45, 60Row Three: 45, 55, 100==============================================
Explanation:
We're told that "40 people responded that they use mouthwash". That means we'll write "40" at the very end of the "use mouthwash" row. This represents the total number of people who use mouthwash, since we're underneath the "total" in that far right column.
Then we're further told that "Of the people who use mouthwash, 30 people use floss", so we'll write "30" in the first row, first column blank space. These are the people who both floss and use mouthwash. Because earlier we know 40 people use mouthwash overall, this leaves 40-30 = 10 people who use mouthwash, but they don't floss.
To summarize so far: In row 1, we have the following values from left to right: 30, 10, 40
The first two items of this row must add to the last item.
---------------------
Now onto row 2
Since 40 people use mouthwash, and 100 people were surveyed, this means that 100-40 = 60 people do not use mouthwash. The value 60 goes at the very end of row 2. This represents another total.
Like earlier, the first two items must add to the last. So 40+60 = 100.
Now turn to the fact that "45 people responded that they don't floss and don't use mouthwash". This tells us that "45" will be in the "no mouthwash" row and "don't floss" column.
We have 60 people who don't use mouthwash, and 45 of those people also don't floss. Therefore, 60-45 = 15 people do floss but they don't use mouthwash. We'll write "15" in the second row, first column.
Along row 2, we have the following values: 15, 45, 60
----------------------
Row 3
For each column, add up the first two items to get the third one. This will lead to the totals along this bottom row.
Floss: 30+15 = 45Don't Floss: 10+45 = 55 .... note how this matches up with the third piece of information your teacher providedThe third column is already done, but again we can see that 40+60 = 100.
Furthermore, the first two items of the third row add to 45+55 = 100 which helps confirm our answers.
The full completed table is shown below.
------------------------
To summarize, we are effectively just sorting the values given to us to write them into the table. Then we use a bit of algebraic detective work to find out what values are missing so we fill out the completed table.
