Step-by-step explanation:

Area of rectangle= l×b

= 4cm×6cm

= 24cm²

Area of circle. = πr²

radius of circle = diameter÷2=6÷2=3cm

Area of circle. = 3.14×3²=3.14×9

Area of circle. = 28.26cm²

[tex]area \: of \: composite \: figure = area \: of \: circle \: + area \: of \: rectangle[/tex]

Area of........... = 28.26cm²+24cm²

= 52.26cm²

PLEASE MARK BRAINLIEST.

The area of the composite shape is: B. 38 cm²

Area of a composite shape = sum of the area of each shape that makes up the composite shape.

Thus:

Area of composite shape = area of semicircle + area of rectangle

= 1/2πr² + length × width

Radius (r) = 1/2(6) = 3 cm

Length = 6 cm

Width = 4 cm

Substitute

Area of composite shape = 1/2(3.14)(3²) + 6 × 4

Area of composite shape = 38 cm²

Answer:

6 cookies

Step-by-step explanation:

Roger wants to place 84 sugar cookies and 66 chocolate chip cookies into plastic bags. Each bag must have the same number of cookies and only one type of cookie must be in each bag.

For the 84 sugar cookies:

number of cookies : 1    2     3      4      6     7      12      14      21     28    42    84

number of bags    : 84   42   28    21    14    12     7        6       4       3      2        1

For the 66 chocolate cookies:

number of cookies : 1       2      3       6      11       22     33      66

number of bags      : 66   33    22     11       6       3        2       1

The maximum common factor between 84 and 66 is 6.

Therefore 6 cookies should be placed in each bag. For sugar cookies, 6 cookies would be placed in each of the 14 bags while for the chocolate cookies, 6 cookies would be placed in each of the 11 bags.

Using proportions, it is found that her monthly salary is of $1,528.9.

A proportion is a fraction of total amount.

In this problem, her monthly sales are $18,545, with a commission of 3.5%, hence, in commission, the amount she makes is:

0.035 x 18545 = 649.075

Her annual salary is $18,995.80, of which 18995.80 - 649 = $18,346.8 she receives in 12 payments, hence:

18,346.8/12 = $1,528.9.

Her monthly salary is of $1,528.9.

It passes the vertical line test, meaning you can draw a vertical line anywhere on the graph and it will only intersect at one point

this means that for every input (x value) there is only one output (y value)

Yes, The graph represents a function.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

We have to show a graph.

Answer:

15 cm

Step-by-step explanation:

Base x height / 2 = Area(of a triangle) =

3 x 10 / 2 =

15 cm

The solution is :  the area of the following triangle is, 15 cm².

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

Here, we have,

given that,

4.2 cm

3 cm

10 cm

We know that,

area = bh/2

i.e. we get,

Base x height / 2

= Area(of a triangle)

substituting the values, we get,

= 3 x 10 / 2

= 15 cm²

Hence, The solution is :  the area of the following triangle is, 15 cm².

[tex]M = 470[/tex] ----- Married persons,

[tex]C = 525[/tex] ---- College graduates,

[tex]PCG = 42[/tex]  ----- Professional college graduates,
