A
,
B
and
C
are points on a circle with
A
C
as a diameter.
A
B
C
is a right-angled triangle.
Work out the total area of the regions shaded in the diagram.
Give your answer correct to 1 decimal place.
Answer:
Area of the shaded portion = 54.5 cm²
Step-by-step explanation:
Solve first for the area of the circle:
[tex]area \: of \: circle = \pi {r}^{2} \\ = \pi( \frac{d}{2} )^{2} \\ = \pi( \frac{10}{2} )^{2} \\ = 25\pi \: or \: 78.5398 {cm}^{2} [/tex]
Then, compute for the area of the triangle:
[tex]area \: of \: triangle = \frac{1}{2} \times base \times height \\ = \frac{1}{2} ( {8})(6) \\ = 24 {cm}^{2} [/tex]
Since we only needed the shaded portion, we have to subtract the area of the triangle from the area of the circle
[tex]25\pi {cm}^{2} - 24 {cm}^{2} = 54.5398 {cm}^{2} [/tex]
Mario received y text messages each minute for 10
minutes yesterday and received t test messages
each minute for 20 minutes today. What is the
total number of text messages he received for two
days in terms of y and t?
a. 30yt
b. 200yt
C. 20y+100
d. 10y+20t
The total number of text messages he received for two days is 10y+20t
What is equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, Mario received y text messages each minute for 10 minutes yesterday and received t text messages each minute for 20 minutes today.
Number of text messages for yesterday = 10y
Number of text messages for today = 20t
Total = 10y+20t
Hence, The total number of text messages he received for two days is 10y+20t

m∠1=(3x+8)°, m∠2=(3x+18)°, and m∠3=(7x+9)°. What is m∠3?
Answer:
87.4°
Step-by-step explanation:
(3x + 8) + (3x + 18) + (7x + 9) = 180
3x + 8 + 3x + 18 + 7x + 9 = 180
add the common numbers
13x + 35 = 180
subtract 35
13x = 145
divide 13
x = 11.2
then plug it back in to m<3
7(11.2) + 9
78.4 + 9
= 87.4°

O salário de um artista é calculado através da função y = 2000 + 500x onde Y representa o valor total em Reais recebido em um mês de trabalho e "x" o número de shows realizados no mês. Qual foi o salário desse artista no mês em que realizou 12 shows?
Answer:
The artist's salary in the month is 8000.
Step-by-step explanation:
The salary of an artist is given by the function :
y = 2000 + 500x ....(1)
where Y represents the total amount in Reais received in a month of work and "x" the number of shows performed in the month.
We need to find the artist's salary in the month she performed 12 shows.
Put x = 12 in equation (1)
y = 2000 + 500(12)
= 2000 + 6000
= 8000
Hence, the artist's salary in the month is 8000.

The perimeter of a rectangle is forty inches. The length is
two inches more than three times the width. Find the dimensions of
the rectangle.
Let Width (inches) = X
Let Length (inches) = 3x + 2
40 = (x) + (3x + 2) + (x) + (3x +2)
40 = 8x + 4
-4 -4
36 = 8x
/8 /8
4.5 = x (width)
Length = 3x + 2
length = 3(4.5) + 2
length = 13.5 + 2
length = 15.5 inches
CHECK
40 = 15.5 + 4.5 + 15.5 + 4.5
40 = 20 + 20
40 = 40
