Step-by-step explanation:
Reflecting over the y axis does not change the Y value. It multiplies the x value by -1.
So (-1,11) is (1,11)
And (-3,-9) would become (3,-9)
And (2,-7) would become (-2,-7)

p is supplemetary to n
z and 50 are opposites in a quadrilateral
The wheel of the Singapore Flyer is a circle with a diameter of 150 metres. Calculate the circumference of the wheel. Give your answer correct to the nearest metre.
Answer:
circumference is given by πd, where d is the diameter of the circle.
This implies, the circumference= 22/7*150m
=3300/7=471.429m
The lines of symmetry in a regular polygon are equal to the number of sides minus 2. True or False
Answer:
False
Step-by-step explanation:
A regular polygon may be defined as the polygon that have sides of equal length known as equilateral and angles made up of equal angles, known as equiangular.
The [tex]$\text{number of lines}$[/tex] of symmetry in a regular polygon is always equal to the number of sides of the polygon. For example, a regular pentagon have 5 sides, so the lines of symmetry of the regular pentagon is also 5, a square having 4 sides also has 4 lines of symmetry.
Expand and combine like terms.
(6y^2+ 5y^4)^2
Answer:
36y⁴ + 60y⁶ + 25y⁸
Step-by-step explanation:
(6y² + 5y⁴)² = (6y² + 5y⁴)(6y² + 5y⁴)
we can use the FOIL method to get:
36y⁴ + 30y⁶ + 30y⁶ + 25y⁸
we can simplify the two middle terms and get:
36y⁴ + 60y⁶ + 25y⁸
Answer:
[tex]\left(6y^2+5y^4\right)^2[/tex]
[tex](6y^2+5y^4)^2=36y^4+60y^6+25y^8[/tex]
[tex]=\left(25y^8+60y^6+36y^4\right)[/tex]

The sound of a jet engine of a skyhawk jetfighter is 70000 times louder than the sound of a lawnmower if the lawnmower has the loudness of 88db then what is the loudness of the jet engine rounded to the 1DP
Answer: 6,160,000 db
Step-by-step explanation:
The sound of a jet engine is 70,000 times louder than that of a lawn mower.
Since we know the sound of a lawnmower, we can multiply that by 70,000 to find the sound of a jet engine:
= Sound of lawnmower * 70,000
= 88 * 70,000
= 6,160,000 db
A student has an average (arithmetic mean) score
of 86 points for 4 tests. What total score does this
student need in the next two tests in order to have
an average of 90 for all 6 tests?
Please help!! Thank you!
Answer:
90 & 96
Step-by-step explanation:
if you add them and mean them you will conclude this solution
The total score this student needs in the next two tests in order to have an average of 90 for all 6 tests will be 196.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
A student has an average (arithmetic mean) score of 86 points for 4 tests.
The total number of 4 tests will be
→ 86 x 4
→ 344
Then the total score this student needs in the next two tests in order to have an average of 90 for all 6 tests will be
The total number of 6 tests will be
→ 6 x 90
→ 540
Then the score in the last 2 tests will be
→ 540 - 344
→ 196

Find the missing angle measure, arc measure of solve for x. Show all work!
Answer:
hmmmmm
Step-by-step explanation:
Answer:
m∠SRT = 47°
Step-by-step explanation:
The measure of an inscribed angle is 1/2 the measure of the intercepted arc.
So,
16x - 1 = 1/2(30x + 4) = 15x + 2
x - 1 = 2
x = 3
m∠SRT = 16(3) - 1 = 48 - 1 = 47
The length of a trip varies directly as the amount of gasoline used. Yael's car used 16 L for the first 145 km of his trip from Toronto to Montreal. a) How much gasoline, rounded to the nearest litre, should he expect to use in the remaining 400 km of his trip? b) Can he complete the trip with a budget of $70, if gasoline costs $1.13/L?
Answer:
44
yes. the total cost is 68 which is less than 70
Step-by-step explanation:
There is positive proportionality is two variables are positively related to each other.
The equation for direct proportionality =
y = bx
where y = dependent variable
b = constant
x = independent variable
amount of gasoline = b x length of the trip
16 = b x 145
b = 16/145 = 0.110345
a. 400 x 0.110345 = 44
total litres used for the trip = 44 + 16 = 60
total cost of the trip = 60 x 1.13 = 67.8
total amount spent on gasoline is 67.8. this is less than the budget

|x-1|-1=1 what’s the value of x
Answer:
x=3, x=-1
Step-by-step explanation:
|x-1|-1=1
Add 1 to each side
|x-1|-1+1=1+1
|x-1|=2
Now set the absolute value to ±2
x-1 = 2 and x-1 = -2
Add 1 to all sides
x-1+1 = 2+1 x-1+1 = -2+1
x=3 x = -1

seconde
et la part du troisième est égale aux trois quarts de la somme des parts des deux autres.
Calculer la part de chaque personne.
Answer:
P 2.680 S 2.920 T 4.200
Step-by-step explanation:
S = seconde
Premiere = S-240
Troisieme = 3/4( 2S -240)
S + S-240 + 3/4(2S-240) = 9800
Multiplie tout par 4 pour eliminer la fraction
4S + 4S -960 + 6S - 720 = 39200
14 S = 40.880
S = 2.920
P = 2.920-240 = 2.680
T =3/4(5.600) = 4.200
2.920 + 2.680 + 4.200 = 9.800

Use the function r(x)=2x+1
if r(b)=19 what is the value of b?
Let's think of this like a point. We know the y-value, but not the x-value. Therefore, in order to find b, we should plug in our known y-value, 19, for r(x).
19 = 2b + 1 || We can leave it as x in our equation or change it to b. Either way you will get the same answer. I changed it to b in this case just to follow through with what the question is asking.
18 = 2b
b = 9
Hope this helps!! :)
Answer:
9
Step-by-step explanation:
They are asking what value of x can you input into 2x+1 so that the outpot is 19.
In other words, you need to solve 2x+1=19.
Subtracting 1 on both sides gives: 2x=18.
Dividing 2 on both sides gives: x=9.
So r(9)=19 since 2(9)+1 is 19.

A theatre has seats arranged in rows of 24, three hundred eighty -two(382) people attend a show at the theatre. What is the smallest number of rows that is needed to seat these people?
Answer:
Smallest number of rows that is needed to seat these people = 16
Step-by-step explanation:
Given - A theatre has seats arranged in rows of 24, three hundred eighty -two(382) people attend a show at the theatre.
To find - What is the smallest number of rows that is needed to seat these people?
Solution -
Given that,
Total number of seats in a Row = 24
Let us assume that, there are x rows
As.
There are 382 people in the Theatre
So,
Minimum seats required is
24 x = 382
⇒x = 382 ÷ 24
⇒x = 15.91
i.e.
Smallest number of rows that is needed to seat these people = 16

Answer: Choice B) SAS
=======================================================
Explanation:
The sides that have the double tickmarks are the same length. This forms one "S" of "SAS".
The square angles are 90 degree angles, or right angles. They are congruent. This forms the "A" of "SAS".
The overlapping sides are the same length, which forms the second "S" of "SAS".
The angle is between the two sides allowing us to use SAS. The order is important.

the height in feet above the ground of an arrow after it is shot can be modeled by y=-16r^2+63r+4.Can the arrow pass over a tree that is 68 feet tall? Explain.
Answer:
yes
Step-by-step explanation:
y=-16r^2+63r+4
maximum value of y :
y'=0
-32r +63=0
r= 63/32
y = -16(63/32)²+63(63/32)+4
= -4 + 124 + 4 = 124 ft
124 > 68
the Arrow can pass over the tree
