Find the distance of AB.
Answer:
3
Step-by-step explanation:
A ( 2, 2 )
( x1, y1 ) = ( 2, 2 )
Here,
x1 = y1 = 2
B ( - 2, - 2 )
( x2, y2 ) = ( - 2, - 2 )
Here,
x2 = y2 = - 2
Distance formula : -
d = √ ( x2 - x1 )² + ( y2 - y1 )²
AB = √ ( - 2 - 2 )² + ( - 2 - 2 )²
= √ ( - 2 )² + ( - 2 )²
= √ 4 + 4
AB = √8
The value of √8 is 2.828.

Q1. For each of the following values of a,b and c, where
(a) a = -20, b = -10, c = 5
(b) a = -40, b = 10, c = -5
Show that:
(i) a÷b ≠ b÷a
(ii) (a÷b)÷c ≠ a÷(b÷c)
(iii) a÷(b+c)≠(a÷b)+(a÷c)
Explanation:-
⟨a⟩Given that
a = -20
b = -10
c = 5
⟨i⟩ LHS = a÷b
⇛ -20÷-10
⇛ -20/-10
⇛ 2
and
RHS = b÷a
⇛ -10÷-20
⇛ -10/-20
⇛ 1/2
LHS ≠ RHS
a÷b ≠ b÷a
⟨ii⟩
LHS = (a÷b)÷c
⇛ (-20÷-10)÷5
⇛ 2÷5
⇛ 2/5
RHS = a÷(b÷c)
⇛ -20÷(-10÷5)
⇛ -20÷-2
⇛ -20/-2
⇛ 10
LHS ≠ RHS
(a÷b)÷c ≠ a÷(b÷c)
⟨iii⟩ LHS = a÷(b+c)
⇛ -20÷(-10+5)
⇛ -20÷(-5)
⇛ -20/-5
⇛ 4
RHS = (a÷b)+(a÷c)
⇛ (-20÷-10)+(-20÷5)
⇛ 2+(-4)
⇛ 2-4
⇛ -2
LHS ≠ RHS
a÷(b+c) ≠ (a÷b)+(a÷c)
⟨b⟩.Given that
a = -40
b = 10
c = -5
⟨i⟩ LHS = a÷b
⇛ -40÷1
⇛ -40/1
⇛-40
and
RHS = b÷a
⇛ 10÷-40
⇛ 10/-40
⇛ -1/4
LHS ≠ RHS
a÷b ≠ b÷a
⟨ii⟩.
LHS = (a÷b)÷c
⇛ (-40÷10)÷-5
⇛ -4÷-5
⇛ 4/5
RHS = a÷(b÷c)
⇛ -40÷(10÷-5)
⇛ -40÷-2
⇛ -40/-2
⇛ 20
LHS ≠ RHS
(a÷b)÷c ≠ a÷(b÷c)
⟨iii⟩ LHS = a÷(b+c)
⇛ -40÷(10-5)
⇛ -40÷(5)
⇛ -40/5
⇛ -8
RHS = (a÷b)+(a÷c)
⇛ (-40÷10)+(-40÷-5)
⇛ (-4)+8
⇛ 8-4
⇛ 4
LHS ≠ RHS
a÷(b+c) ≠ (a÷b)+(a÷c)

Pierre's unicycle wheel has a diameter of 80 cm.
a) How far does the unicycle move if the
wheel turns once?
Give your answer in metres, correct
to 2 decimal places.
b) Pierre enters a 100 m unicycle race.
How many times must the wheel rotate
completely in order for Pierre to
travel 100 m?
Give your answer to the nearest
whole number.
Answer:
a) 251.33 cm
b) 40 times
Step-by-step explanation:
C = d x r
a) C = 80 cm x 3.14 = 251.33 cm
b) 100 m = 10,000 cm
10,000cm/251.33cm = 40 times
My question is in the picture, I WILL GIVE BRAINLIEST AND YOUR GETTING REWARDED 50 POINTS.
Answer:
The form for a point-slope equation is y-y1=m(x-x1), where ”m” is the slope and (x1,y1) is a point on the graph. Substituting in the slope and point, the equation is y+7=-4(x-2).

Make x the subject of the formula ax+2d=5cx+3b
Answer:
x = [tex]\frac{3b-2d}{a-5c}[/tex]
Step-by-step explanation:
ax + 2d = 5cx + 3b ( subtract 5cx from both sides )
ax - 5cx + 2d = 3b ( subtract 2d from both sides )
ax - 5cx = 3b - 2d ← factor out x from each term on the left side
x(a - 5c) = 3b - 2d ← divide both sides by (a - 5c)
x = [tex]\frac{3b-2d}{a-5c}[/tex]
A right triangle has a hypotenuse that is between 28 and 29 units long. Name two pairs of lengths that could be the lengths of the legs of the right triangle
Answer:
5.3 of both lengths, if the lengths are the same
Step-by-step explanation:
28 squared equals 5.29... which rounds up to 5.3 if you're trying to find a number rounded up to the tenths. I also tried with 5.2 and 5.4, but they weren't in btw. 28 and 29, so the answer must be 5.3

it takes 22 minutes to go 1 mile on horseback. at this rate, how long will it take tim to go 6 miles
Answer:
132 minutes
Step-by-step explanation:
If you see that 1 mile is 22 minutes, then you would know 2 miles is double, three miles is triple and so on. So you would do 22x6 for the six miles to get your answer of 132, or you can even do 22 plus 22 six times.
Answer:
132 minutes = 2 hours and 12 minutes
Step-by-step explanation:
22 x 6 = 132 (minutes)
to find it in hours:
132 divided by 60 = 2.2 (2 hours)
2 x 60 = 120
132 - 120 = 12 (minutes)
(-2,2) reflected in the line y=-1
Answer:
(-2,-4)
Step-by-step explanation:
Graph it and you would find that (-2,2) is 3 units higher than the line y=-1. So you would reflect it across by starting at (-2,-1) and count downwards, 3 to get (-2,-4).

what statement makes the open sentence 12 + 3x = 30 true?MUTIPLE CHOICE QUESTION WILL MARK BRAINLIEST
(x=2), (x=4), (x=5), (x=6)
Answer:
x= 6
Step-by-step explanation:
12+3x=30
3x+12=30
3x+12-12=30-12
3x=30-12
3x=18
3x divided by 3 = 18 divided by 3
x=18 over 3
18 divided by 3 is 6
x=6
Answer:
x = 6
Step-by-step explanation:
12 +3x = 30
Subtract 12 from both sides
3x = 30 - 12
3x = 18
Divide both side by 3
x = 18/3
x = 6

3)-3(v + 25) = 111
Use distributive property
-3v + (-3)*25 = 111
-3v - 75 = 111
Add 75 to both sides
-3v = 111+ 75
-3v = 186
Divide both sides by (-3)
v = 186/(-3)
v = -62

The following ratio gives us a unit rate of 2 feet per second.
Fill in the missing number in the ratio.
?/10 foot : 1/4 second
Step-by-step explanation:
2 ft / 1 second
and now
x/10 foot / 1/4 second
we need to multiply the original ratio by 1/4 to get the same denominator :
2/1 × (1/4)/(1/4) = (2/4) / (1/4) = (1/2) / (1/4)
how many 10th foot are 1/2 ?
we need to bring 1/2 to the denominator of 10.
1/2 = x/10
10 = 2x
x = 5
so, 1/2 = 5/10
therefore, or answer is
5/10 foot / 1/4 second

which is the better but?A dozen eggs for $2.50 or one egg at a time on sale for $0.20 each
pls help
Answer:
single egg
Step-by-step explanation:
0.20 x 12 = 2.40
regular = 2.50
Answer:
one egg a time
Step-by-step explanation:
We know a dozen eggs consists of 6eggs and in total it costs $2.50
Now 1 egg is $0.20 when you buy 5 more eggs separately it gives you a total amount of $1.25 so you save more money when you buy one egg at a time
School rules permit no fewer than 2 teachers per 25 students. There are at least 245 students enrolled in the school. If x represent teachers and y represents students, which system of linear inequalities can be used to determine the possible number of teachers and students at the school?
2y ≥ 25x and y ≥ 245
2y ≤ 25x and y ≥ 245
25y ≤ 2x and y ≥ 245
25y ≥ 2x and y ≥ 245
Answer:
(b) 2y ≤ 25x and y ≥ 245
Step-by-step explanation:
You want the teacher/student ratio to be at least 2/25, so ...
x/y ≥ 2/25
25x ≥ 2y . . . . . multiply by 25y
2y ≤ 25x . . . . . swap sides to get the form used in answer choice B
The other inequality says the number of students is at least 245:
y ≥ 245
Answer:
B- 2y ≤ 25x and y ≥ 245

Find the value of x.
(Round to the nearest tenth as needed.)
Answer:
27.7 degrees
Step-by-step explanation:
We can use the inverse sine to find the angle x as we are given the opposite sided length and the hypotenuse
x = sin-1(13/28)
x = 27.66
x = 27.7 (round to tenths)

12=2(7x + 8)
Step-by-step explanation:
2(7x +8)=12
2(7x +8)/2 =12/2
7x +8 =6
7x=6-8
7x = -2
x= -2/7
Hi there! :)
12=2(7x+8)
Use the Distributive property:
12=14x+16
Move all the numbers to the right side and the variables to the left side:
-14x=16-12
-14x=4
Divide both sides by -14 to isolate x:
x=[tex]-\frac{4}{14} \\-\frac{2}{7}[/tex]
Therefore, x=[tex]-\frac{2}{7}[/tex]Hope this helps you!
