Estimate 16.82-8.264 by first rounding each number to the nearest tenth.
pls help i need the right answer!
Answer:
so the answer is about 8.40
Steps
--------------------------------------------------------------------------------------------------------------
find the number in the tenth place and look one place to the right for the rounding digit. Round up if the number is greater than or equal to 5 but since 2 is less than 5, stays the same
16.820⇒16.82
--------------------------------------------------------------------------------------------------------------
8.264⇒8.364
Remember round up if the number is greater than or equal to 5 and round down if the number is less than 5.
--------------------------------------------------------------------------------------------------------------
now that we have rounded everything. It is time to estimate 16.82-8.364.
16.82 is close to 16.80 and 8.364 is close to 8.40.
16.80-8.40=8.40

Find the coordinates for the point Y that lies on the directed segment from X(-1,3) to Z(5,6) and partitions the segment in the ration 2:3
Answer:
(2.6, 4.8)
Step-by-step explanation:
The midpoint segment formula is expressed as;
M(X, Y) = [(ax2+bx1)/a+b, (ay2+by1)/a+b]
X = ax1+bx2)/a+b
Y = ay1+by2)/a+b
Given X(-1,3) to Z(5,6) and a = 2, b = 3
X = 2(-1)+3(5)/2+3
X =(-2+15)/5
X =13/5
X = 2.6
Similarly;
Y = 2(3)+3(6)/2+3
Y =(6+18)/5
Y =24/5
Y = 4.8
hence the required coordinate of Y is (2.6, 4.8)

Resuelve los siguientes triángulos rectángulos encontrando todos los datos faltantes
Respuesta:
A = 51,167
b = 28,5 pies
c = 45,4 pies
Explicación paso a paso:
C = 90 °
B = 38 ° 50 '
Convertir B a grado
1 ° = 60 '
x ° = 50 '
Multiplicar en cruz:
60x = 50
x = 50/60
x = 0,83333 °
Por lo tanto, 38 ° 50 '= 38 ° + 0.833 ° = 38.833 °
Recordar :
A + B + C = 180 ° (Suma de ángulos en un triángulo)
A + 38.833 + 90 = 180
A + 128.833 = 180
A = 180 - 128,833
A = 51,167 °
Usando identidades trigonométricas, podríamos encontrar byc
Para obtener b:
Tan B = opuesto / adyacente = b / 35.4
Tan 38,833 = b / 35,4
b = Tan 38,833 * 35,4
b = 28,5 pies
Para obtener c:
Podríamos usar:
Sin A = opuesto / hipoteno = 35,4 / c
Sin 51,167 = 35,4 / c
c * sin 51,167 = 35,4
c = 35,4 / sen 51,167
c = 45,4 pies

x/9=15/2 rounded to the nearest tenth
20/8.7=5.8/x to the nearest tenth
5/16=11/x nearest tenth
x/0.06=17/0.5 to the nearest tenth
29/x=75/44
Answer:
1. x = 67.5
2. x = 2.5
3. x = 35.2
4. x = 2.0
5. x = 17.0
Step-by-step explanation:
Question 1
The proportion is set up in the form x/9 = 15/2. Multiply both sides by two to get rid of the two in the denominator on the right side. After doing so, multiply by 9 on both sides to get rid of the 9 in the denominator on the left:
2x/9 = 15
2x = 9(15)
Next solve for x:
2x = 135
x = 67.5
Question 2
The proportion is set up in the form 20/8.7 = 5.8/x. Multiply both sides by the second denominator, x, and then both sides by the first, 8.7. This will leave you with the work below:
20x/8.7 = 5.8
20x = 8.7(5.8)
Next, solve for x:
20x = 50.46
x = 2.523
Round to the nearest tenth:
x = 2.5
Question 3
The proportion is set up in the form 5/16 = 11/x. Multiply both sides by the second denominator, x, and then both sides by the first, 16. This will leave you with the work below:
5x/16 = 11
5x = 11(16)
Next, solve for x:
5x = 176
x = 35.2
Question 4
The proportion is set up in the form x/0.06 = 17/0.5. Multiply both sides by the second denominator, 0.5, and then both sides by the first, 0.06. This will leave you with the work below:
0.5x/0.06 = 17
0.5x = 17(0.06)
Next, solve for x:
0.5x = 1.02
x = 2.04
Round to the nearest tenth:
x = 2.0
Question 5
The proportion is set up in the form 29/x = 75/44. Multiply both sides by the second denominator, 44, and then both sides by the first, x. This will leave you with the work below:
29(44)/x = 75
29(44) = 75x
Next, solve for x:
1276 = 75x
x = 17.0133
Round to the nearest tenth:
x = 17.0
4. The route for Millburn's Fourth of July parade stretches 2 miles (10,560 feet).
Spectators are usually evenly distributed along both sides of the route. Along one
side of 50 feet of the route, you count 15 children. Estimate the number of children
who attended the parade.
PLEASEEE HELP
Answer:
The estimated number of children who attended the parade is 6,336.
Step-by-step explanation:
Since the route for Millburn's Fourth of July parade stretches 2 miles (10,560 feet), and spectators are usually evenly distributed along both sides of the route, and along one side of 50 feet of the route, you count 15 children, to estimate the number of children who attended the parade, the following calculation must be performed:
(10,560 / 50) = 211.2
211.2 x 15 x 2 = X
211.2 x 30 = X
6.336 = X
Therefore, the estimated number of children who attended the parade is 6,336.

Answer:
x= -1 y= -5
There for: (x, y). (-1,-5).
Step-by-step explanation:
Step one:
y=y
5x=9x+4
5x-9x=4
-4x=4
x= -1
Step two:
y=5x
y= 5(-1)
y= -5
Hope u find this helpful
Step-by-step explanation:
y=5x
y=9x+4
Substituting value of x in equation 2
y=9x+4
5x=9x+4
5x-9x=4
-4x=4
so x = -1
again
y=5x
y=5 * (-1)
so y = -5.

There are 20 questions in a quiz. Each correct answer scores 7 points, each wrong answer scores -4 points and each question left blank scores 0 points. Eric took the quiz and scored 100 points. How many questions did he left blank?.
He answered 16 questions correctly, and got 3 wrong answers.
==========================================================
Explanation:
Let
x = number of questions that are correct y = number of wrong answers z = number of questions left blankx,y,z are nonnegative whole numbers.
-------------------
Since there are 20 questions total, this means the first equation to set up is:
x+y+z = 20
Solving for y leads to
x+y+z = 20
y+z = 20-x
y = 20-x-z
We'll use this later.
-------------------
Another equation to set up is 7x-4y = 100 because Eric earns 7 points per correct answer and loses 4 points for each incorrect answer, and all that leads to 100 points total which was his quiz score. We'll ignore the questions he left blank since they add 0 points.
Let's plug the equation in which we isolated y
7x-4y = 100
7x-4(20-x-z) = 100
7x-80+4x+4z = 100
7x+4x+4z = 100+80
11x+4z = 180
-------------------
Now we can guess and check to see which pair of x and z values will make that last equation above true. I suggest starting with the smallest possible value of x and using that x value to solve for z.
If x = 0, then,
11x+4z = 180
11(0)+4z = 180
4z = 180
z = 180/4
z = 45
So if Eric got 0 correct answers, then he left 45 questions blank. But that isn't possible because there are only 20 questions total. So we'll ignore the case that x = 0.
If we increase x by 4, and decrease z by 11, then we get another ordered pair solution to this equation
So another solution is (x,z) = (4,34)
Note that
11x+4y = 180
11(4) + 4(34) = 180
But like before, z = 34 isn't possible since 20 is the max.
Increase x by 4 again, and drop z by 11 to get (x,z) = (8,23). Again we run into the same issue as before.
Increase x by 4 again, and decrease z by 11 to get (x,z) = (12, 12). Now we have both x and z smaller than 20, but note how x+z = 12+12 = 24 which exceeds the total number of questions. So we rule this case out as well.
Do another round of "increase x by 4, decrease z by 11" to get to (x,z) = (16, 1). This is the only case left because anything beyond this, z will be negative.
Luckily, this final case does work. If Eric answers x = 16 questions correctly, then he left z = 1 of them blank. That must mean y = 20-x-z = 20-16-1 = 3 questions were incorrect.
We can see that:
7x-4y = 7(16)-4(3) = 112-12= 100
meaning that (x,y) = (16,3) is a solution to 7x-4y = 100.
-------------------
To summarize, we found that the only possible solution is (x,y,z) = (16, 3, 1)
Meaning x = 16 questions were correct, y = 3 were wrong, and z = 1 question was left blank.
