Find the area of the shaded part of circle Y.
Answers
Answer:
201.45 cm²
Step-by-step explanation:
The whole circle has an area of π(9)² cm², or 81π cm². The shaded part represents all of the circle except for the chunk swept out by sector XZ.
Sector XZ sweeps out 75°, which represents 75/360 of the whole circle, or, simplified, 15/72. That means the shaded area must represent the other 57/72. To find the area then, we can just multiply that fraction by 81π:
[tex]81\pi\cdot\frac{57}{72}=9\pi\cdot\frac{57}{8}[/tex]
Using π ≈ 3.14 and crunching the numbers out gives us a result of approximately 201.45 cm².

Step-by-step explanation:
Complete question
(Emyr sat his gcse math exam.he scored a total of 112 out of the 200 posible. What is her mark percentage?)
To calculate the percentage of a value, we first of all take the value obtained divided by the total possible value obtainable multiply by 100.
In this case, the value obtained was 112 and the total value obtainable is 200.
x = (112 / 200) * 100
X = 0.56 * 100
x = 56%.
The percentage of his score was 56%

Saj makes Rose Pink paint and Cherry Pink paint. He mixes red paint with white paint as shown. Rose Pink red : white =1:2 Cherry Pink red : white =4:3 He makes 60 litres of Rose Pink paint. To this Rose Pink paint he adds 80 litres of red paint and 28 litres of white paint. Has he now made Cherry Pink paint? You must show your working.
Answers
Answer:
No. He had not made cherry pink paint
Step-by-step explanation:
Rose Pink red : white = 1 : 2
Cherry Pink red : white = 4 : 3
...he adds 80 litres of red paint and 28 litres of white paint.
The question basically want us to check if it follows the ratio.
To have the cherry pink, the ratio must be 4:3 however the ration of paint he mixed is;
80 : 28 which is equivalent to 20 : 7
This means he had not made cherry pink paint
Adding 80 litres of red paint and 28 litres of white paint to the 60 liters of Rose pink paint does not make Cherry pink paint
The ratios are given as:
Rose pink paint-> Red : White = 1 : 2
Cherry pink paint-> Red : White = 4 : 3
When he makes 60 liters of Rose pink paint, the proportion of white and red paints are:
[tex]Red = \frac{1}{1 + 2} \times 60[/tex]
[tex]Red = 20[/tex]
[tex]White = \frac{2}{1 + 2} \times 60[/tex]
[tex]White = 40[/tex]
He then adds 80 liters of red and 28 liters of white paints.
So, the new proportions are:
[tex]Red = 20+80[/tex]
[tex]Red = 100[/tex]
[tex]White = 40+28[/tex]
[tex]White = 68[/tex]
Express as ratio
[tex]Red : White = 100 : 68[/tex]
Simplify to the smallest term
[tex]Red : White = 25 : 17[/tex]
25:17 is not equivalent to 4:3.
Hence, he has not made Cherry pink paint

Answers
one of the trigonometry rules is sin^2(x) + cos^2(x) = 1 if you rearrange this you realize that sin^2= 1-cos^2(x)
we also know that csc^2(x)= 1/sin^2(x) so now you can rewrite your equation as:
sin^2(x) x 1/sin^2(x) = 1
sin^2(x)/sin^2(x) =1
the LHS (left hand side) can cancel down to 1 because the numerator and denominator are the same
so then 1=1 Therefore LHS=RHS

= 1.23%
Answer:
1.23
Step-by-step explanation:
Hey there !!!!!
4.1% of 30
if we solve it :
Y is 4.1% of 30
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 4.1% * 30
Converting percent to decimal:
p = 4.1%/100 = 0.041
Y = 0.041 * 30
Y = 1.23
therefore:
4.1% of 30 = 1.23

∠ HGL = 73°
Step-by-step explanation:
KL is a midsegment of the triangle and is parallel to HG, then
∠ KLJ = ∠ HGL ( corresponding angles ), so
9x - 62 = 5x - 2 ( subtract 5x from both sides )
4x - 62 = - 2 ( add 62 to both sides )
4x = 60 ( divide both sides by 4 )
x = 15
Thus
∠ HGL = 5x - 2 = 5(15) - 2 = 75 - 2 = 73°
