Answer:
n = 11
Step-by-step explanation:
n+5=2n-6
you add 6 on both sides and you get
n+11=2n
you then subtract n on both sides and get
11=n
Step-by-step explanation:
n+5 = 2n - 6 -> Original equation
5 = n - 6 -> Take n away from both sides
11 = n -> Add 6 to both sides
n = 11 -> Final answer
*Remember, we are trying to get n by using inverse operations.
A hiker travels 1.13 kilometers south, then travels 2.25 kilometers east. What’s the hiker’s displacement for the trip?
Answer:
Total displacement = 2.52 kilometers [south east][tex]a^2 + b^2 = c^2\\1.13^2 + 2.25^2 = c^2\\c^2 = 6.3394\\c = 2.52[/tex]

Can someone tell me if this is correct if not please correct me in the wrong ones
Answer:
The answer to 2 is "acute".
The answer to 6 is "right triangle"
For 10, it actually is possible. An example is 50, 50, 80
Step-by-step explanation:
An acute triangle is when each angle is less than 90 degrees.
Any triangle with 90 degrees for one angle counts as a right triangle.
all angle measures in a triangle must add up to 180 degrees. Hope this helps!

im confused
Answer:
Angels D and G
Step-by-step explanation:
Alternate exterior angles are formed by a transversal intersecting two parallel lines . They are located "outside" the two parallel lines but on opposite sides of the transversal, creating two pairs (four total angles) of alternate exterior angles. Although in this case angels D and G dont have opposite angels so in this cade their is only 2 alternate exterior angels.
I hope this helps have a great day and happy holidays (｢•-•)｢
Answer:
∠D and ∠G
Step-by-step explanation:
Think about what alternate exterior angles are:
"Alternate" means on either side of each other"Exterior" means outside (the transversal BI).Putting these two elements together, we can clearly see the alternate exterior angles are ∠D and ∠G.
After a rotation, A(-3,4) maps to A/4, 3), B(4.-5) maps to BY-5,-4), and C(1,6) maps to C(6.-1). Which rule
describes the rotation?
O RO 90
O Ra 180°
O Ro 270
ORO 360°
Answer:
3rd option
Step-by-step explanation:
Under a rotation about the origin of 270°
a point (x, y ) → (y, - x ) , then
A (- 3, 4 ) → (4, - 3 )
B (4, - 5 ) → (- 5, - 4 )
C (1, 6 ) → (6, - 1 )
The center of rotation is therefore (h, k) = (1/2, 7/2), and the rule for the rotation is R90 (a 90-degree counterclockwise rotation about the point (1/2, 7/2)).
What is coordinate plane?The coordinate plane is a two-dimensional plane formed by the intersection of a horizontal number line, called the x-axis, and a vertical number line, called the y-axis.
The given information suggests that each point has been rotated 90 degrees counterclockwise around some point (h, k) on the coordinate plane.
To find this point, we can use the fact that the midpoint of the line segment joining each point to its image must be the center of rotation.
Midpoint of segment AA'/4: ((-3 + 4)/2, (4 + 3)/2) = (1/2, 7/2)
Midpoint of segment BB'/5: ((4 - 5)/2, (-5 - 4)/2) = (-1/2, -9/2)
Midpoint of segment CC'/6: ((1 + 6)/2, (6 - 1)/2) = (7/2, 5/2)
Thus, the center of rotation is therefore (h, k) = (1/2, 7/2), and the rule for the rotation is R90 (a 90-degree counterclockwise rotation about the point (1/2, 7/2)).

Lily has $2. 75 in her pocket, consisting of dimes and quarters. If there are 17 coins in all, how many of each does she have?.
Answer:
Lily has 7 Quarters and 10 Dimes
Step-by-step explanation:
Let's use pennies instead of $.
Let D and Q stand for the numbers of Dimes and Quarters, respectively.
We are told that there are 17 coins total:
D + Q = 17
We also learn that they amount to 275 (pennies). We can write that as:
10D + 25Q = 275 [Each D is worth 10 pennies, etc.]
We have two equations and two unknowns. We can rearrange one equation to find the value of either of the unknowns, and then use that it the second equation.
I'll rearrange the first:
D + Q = 17
D = 17 - Q
Now use this value of D in the second equation:
10D + 25Q = 275
10(17-Q) + 25Q = 275
170 - 10Q + 25 Q = 275
15Q = 105
Q = 7 : 7 Quarters.
Since D + Q = 17:
D + 7 = 17
D = 10 Dimes
==========================================
Let's check these results:
Q = 7 Quarters
D = 10 Dimes
1. Is this 17 coins in total? (7+10 = 17) YES
2. Does this add to $2.75? (10*10) + (7*25) = 275 cents?
(100 + 176) = 275 (cents) YES
============================
Lily has 7 Quarters and 10 Dimes

Find the measure of the indicated angle in the triangle.
Answer:
70°
Step-by-step explanation:
The V angle is complementary with the R which means that
120° + V angle = 180° Therefore V = 60°
The sum of the internal angles of the triangles equals 180.
We have 50° + 60° + U = 180
70° is the answer

What is the value of b for the following circle in general form? x2 + y2 + ax +by+c=0
Answer:
Step-by-step explanation:
(1). (x - h)² + (y - k)² = r²
where (h, k) are coordinates of a center of the circle with radius r
(2). ( a ± b )² = a² ± 2ab + b²
~~~~~~~~~~~~~~
( 1 , - 2 ) ; r = 3
( x - 1 )² + ( y + 2 )² = 3²
x² - 2x + 1 + y² + 4y + 4 = 9
x² + y² - 2x + 4y - 4 = 0
a = - 2
b = 4
c = - 4
a-y= b+y/a make y subject
Answer:
y = [tex]\frac{a^2-ab}{a+1}[/tex]
Step-by-step explanation:
a - y = b + [tex]\frac{y}{a}[/tex] ( multiply through by a to clear the fraction )
a² - ay = ab + y ( subtract y from both sides )
a² - ay - y = ab ( subtract a² from both sides )
- ay - y = ab - a² ← factor out y from each term on the left side
y(- a - 1) = ab - a² ( divide both sides by - a - 1 )
y = [tex]\frac{ab-a^2}{-a-1}[/tex] ( multiply numerator/ denominator by - 1 )
y = [tex]\frac{a^2-ab}{a+1}[/tex]

Answer:
(4, -2)
Step-by-step explanation:
Use the expression for y given by the first equation to substitute for y in the second equation.
2(2x -10) = x -8 . . . substitute for y

3x = 12 . . . . . . . . add 20-x
x = 4 . . . . . . . . .divide by 3
y = 2(4) -10 = -2 . . . substitute for x in the first equation
The solution is (x, y) = (4, -2).

We've been given to find out the values of x & y from the two given linear equations by substitution method.
Here we have,
y = 2x - 10 - - - - - (1) 2y = x - 8 - - - - - (2)As we have given the value of y i.e (y = 2x - 10) placing this value of y in the second equation we get,

[tex]:\implies\tt{4x - 20 = x - 8}[/tex]

Records show that Oliver is typically 10–30 minutes late for his shift at work. The distribution for the minutes he is late forms a consistent pattern, which can be graphed as the given uniform density curve.
A uniform density curve is at y = StartFraction 1 Over 20 EndFraction.
Company policy requires employees to be less than 12 minutes late for work. What percentage of the time will Oliver meet company policy?
6.7%
10%
60%
90%
Based on the information given, the percentage of time that'll be required to meet the policy will be 10%.
From the complete information, the probability distribution will be:
= 1/(b - a) = 1/(30 - 10) = 1/20
Since the company policy requires employees to be less than 12 minutes late for work, the percentage of the time that Oliver will meet company policy will be:
= (12 - 10) × 1/20
= 2 × 1/20
= 1/10
= 10%
