The diagram shows a sector of a circle radius 10 cm.
Find the area of the sector, giving
your answer correct to 1 decimal place.
135°
10 cm
please give the working out aswell !!
Answer:
Area of sector = 117.6 cm²
Step-by-step explanation:
Radius of sector r = 10 cm
Angle Ф = 135°
We need to find Area of sector
The formula used is: [tex]\mathbf{Area\:of\:Sector=\frac{\theta}{360^{\circ}}\times \pi r^2}[/tex]
Where Ф is the angle, and r is the radius.
Putting values and finding area of sector
[tex]\mathbf{Area\:of\:Sector=\frac{\theta}{360^{\circ}}\times \pi r^2}\\Area\:of\:Sector=\frac{135}{360}\times 3.14 (10)^2\\Area\:of\:Sector=0.375 \times 3.14 \times 100\\Area\:of\:Sector=117.75[/tex]
Now, rounding off answer to 1 decimal place:
[tex]Area\:of\:Sector=117.6\: cm^2[/tex]
So, Area of sector = 117.6 cm²
[Find all the missing side and angles of this triangle]
Step-by-step explanation:
We have AB = 7, Angle ABC = 70°
and Angle ACB = 90°.
Angle BAC = 180° - 70° - 90° = 20°
(Sum of angles in a triangle = 180°)
Using Trignometry,
AC = 7sin70° = 6.58.
BC = 7cos70° = 2.39.
(-3, 11) a solution to the systems of equations: x – 3y = -36 and 3x + 4y = 48
true or false
Answer:
TRUE and FALSE (please look at step-by-step)
Step-by-step explanation:
How to know if it's true or false, you just simply plug in the given numbers to the x and y values.
x = -3
y = 11
for the x - 3y = -36 equation:
-3 -3(11) = -36
-3 - 33 = -36
This equation is true.
for the 3x + 4y = 48 equation:
3(-3) + 4(11) = 48
-9 + 44 = 35
This equation is false.
Find the value of x and y
Step-by-step explanation:
(2x+13)°=3y°
(5y-4)-180=3y
5y-184=3y
5y-3y=184
2y=184
y=92
2x+13=3*92
2x=263
x=131.5
Paulo catches a 7.45 am tram to school. During a period of 79 days, he arrives at school on time 53 occasions. Estimate the probability Paulo:
arrives on time: arrives late:
Answer:
On time: 0.67
Late: 0.33
Step-by-step explanation:
Probabilities
One approach to estimating the probability of occurrence of an event is to record the number of times that event happens (e) and compare it with the total number of trials (n).
The probability can be estimated with the formula:
[tex]\displaystyle P=\frac{e}{n}[/tex]
And the probability that the event doesn't occur is
Q = 1 - P
Paulo arrives on time to school e=53 times out of n=79 times. The probability that he arrives on time is:
[tex]\displaystyle P=\frac{53}{79}[/tex]
P = 0.67
And the probability he arrives late is:
Q = 1 - 0.67 = 0.33

yoko is saving money to buy a bike that costs 125$.She has 60 and will add an additional 5 each week.In how many weeks will she have enough to buy the bikw
Answer:
13 Weeks
Step-by-step explanation:
Yoko currently has $60 so if she gains $5 each week simply 5x13=65
$60+$65=$125
Sue is thinking of buying some 2-liter sodas which are on sale for $1.25 each. The total cost, c, ofall the 2-liter sodas will be proportional to the number of 2-liter sodas, s, that she buys.Which equation represents the relationship between cand s?
Factorise
121ײ + 110 +25 y²
Answer:
(5y+11)²
Step-by-step explanation:
The given expression is :
25y²+110y+121
We need to factors of the given expression.
We know that, (11)² = 121
5² = 25
We can write the given expression as :
25y²+110y+121 = (5y)² + 2(5y)(11) +11²
Using identity : (a+b)² = a²+2ab+b²
25y²+110y+121 = (5y+11)²
Hence, the factors of 25y²+110y+121 is (5y+11)².

The line x-2y=4 and y=2x -2 are
A parallel
B neither
C perpendicular
Answer: B) neither
================================================
Let's isolate y in the first equation. This way we can find the slope.
x-2y = 4
-2y = 4-x
-2y = -x+4
y = (-x+4)/(-2)
y = -x/(-2) + 4/(-2)
y = (1/2)x - 2
This matches with y = mx+b form with m = 1/2 being the slope.
The slope of y = 2x-2 is m = 2
------------------------------
The slope of the first line is 1/2 and the slope of the second line is 2.
Since the two slopes (1/2 and 2) are not equal, this means the lines are not parallel.
Also, the two slopes do not multiply to -1, so the lines aren't perpendicular either.
This leads to B) neither as the final answer.

The point is not a solution for both inequalities, so the point is not a solution for the system of inequalities.
Step-by-step explanation:
y= -5/3x + 3
y= 1/3x - 3
Answer:
y =-2/3x
x = 1
Step-by-step explanation:
adding both equations and then we find the value of y which is given below
y = -2/3x
and then putting the value of y in any above equation then we find the value of X which is given below
X = 1
Write the equation of the line pleaseeee
Answer:
y = 2/3x -1
Step-by-step explanation:
y intersect is -1 as that's where the line passes the y axis
the slope can be found by finding two points and using the slope formula (y-y)/(x-x)

Two snakes race the speed of the first is 24 1/2 inches per minute and the speed of the other is 26 inches per minute how far apart with they be in 3 min? 10 min?
Answer:
In 3 min = 4 1/2
10 min = 15
If you multiply both of the snakes speed by the specific amount of minutes and then subtract both of the sums you'll get the answer :)
