Answer:

C. 27 $cm^{2}$

Step-by-step explanation:

For this problem find the area for the three individual segment then add them together.

Step 1: Find area of the rectangle

formula for area of a rectangle: bxh

b-base

h-height

3x6=18

Step #2: Find area of the triangle

Formula for area of a triangle: $\frac{1}{2} bxh$

b-base

h-height

$\frac{1}{2} (3x3)$ =1/2(9)=4.5

Step #3: Find the area of the triangles total

Because the two triangles have the same area you can just multiply the area of one of the triangles by 2

4.5x2=9

Step #4: Add all the areas together

rectangle+2 triangles

18+9=27

sasho [114]

Answer:

60 different meal packages are possible.

Step-by-step explanation:

Fundamental counting principle:

States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.

In this question:

4 types of drinks

5 types of sandwiches.

3 types of chips.

They are independent events, so, by the fundamental counting principle:

4*5*3 = 60

60 different meal packages are possible.

Can someone help me with 3 a and b?? Thank you

polet [3.4K]

M∠ADB + m∠BDC = m∠ADC [angle addition postulate]

x + x + 10 = 60
2x + 10 = 60
2x = 60 - 10
2x = 50
x = 50/2
x = 25

a
m∠ADB = x = 25°

b
m∠BDC = x + 10 = 25 + 10 = 35°

The circle C has centre A(2,1) and passes through the point B(10,7). Find and equation for C

Semmy [17]

The equation of a circle:
$(x-h)^2+(y-k)^2=r^2$
(h,k) - the coordinates of the centre
r - the radius

$A(2,1) - \hbox{the centre} \\
h=2 \\ k=1 \\ \\
(x-2)^2+(y-1)^2=r^2 \\ \\
\hbox{passes through B(10,7)} \\
x=10 \\
y=7 \\ \\
(10-2)^2+(7-1)^2=r^2 \\
8^2+6^2=r^2 \\
64+36=r^2 \\
r^2=100 \\ \\
\hbox{the equation:} \\ \boxed{(x-2)^2+(y-1)^2=100}$
