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.

Step-by-step explanation:

Given

The distance between them

This is calculated as:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

So, we have:

[tex]D = \sqrt{(3-(-4))^2+(4-(-3))^2}[/tex]

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:

The goal is $19,800.

Step-by-step explanation:

$16,770 is $1,230 less than %90 of the goal. If you add 16,770 and 1,230, you get 18,000. Then you have to multiply that by 1.10 to get it to the goal. That is how you get $19,800, which is the answer.

Answer:

[tex](a)[/tex]  [tex]P(M\ or\ P\ or\ C) = 1.307[/tex]

(b) See Explanation

Step-by-step explanation:

Given

[tex]P = 312[/tex] ---- Professionals,

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

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

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

[tex]MCG = 147[/tex] ----- Married college graduates,

[tex]MP = 86[/tex]  ---- Married professionals,

[tex]MPCG = 25[/tex] ---- Married professional college graduates

[tex]Total =1000[/tex]

Solving (a): P(M or P or C)

This is calculated as:

[tex]P(M\ or\ P\ or\ C) = P(M) + P(P) + P(C)[/tex]

[tex]P(M\ or\ P\ or\ C) = \frac{n(M) + n(P) + n(C)}{Total}[/tex]

[tex]P(P\ and\ T) = \frac{10}{29}[/tex]

[tex]P(P\ and\ T') = \frac{270}{841}[/tex]

Step-by-step explanation:

Given

[tex]n=29[/tex] --- Total

[tex]T = 14[/tex] --- Two person skis

[tex]P = 18[/tex] --- Turbo packs skis

[tex]P\ and\ T = 10[/tex] --- Two person ski and Turbo packs

Solving (a):

This is represented as: [tex]P(P\ and\ T)[/tex]

This is calculated as:

[tex]P(P\ and\ T) = \frac{n(P\ and\ T)}{n}[/tex]

[tex]P(P\ and\ T) = \frac{10}{29}[/tex]

Solving (a):

This is represented as: [tex]P(P\ and\ T')[/tex]

This is calculated as:

[tex]P(P\ and\ T') = P(P)\ and\ P(T')[/tex]

[tex]P(P\ and\ T') = P(P)\ *\ P(T')[/tex]

Using the complement rule, we have:

[tex]P(T') = 1 - P(T)[/tex]

The equation becomes:

[tex]P(P\ and\ T') = P(P)\ *\ [1 - P(T)][/tex]

[tex]P(P\ and\ T') = \frac{n(P)}{n}\ *\ [1 - \frac{n(T)}{n}][/tex]

[tex]P(P\ and\ T') = \frac{18}{29}\ *\ \frac{29-14}{29}[/tex]

[tex]P(P\ and\ T') = \frac{18}{29}\ *\ \frac{15}{29}[/tex]

The required ratio of the unshaded square to the shaded square is 7 : 3.

Given that,
To determine the ratio of the number of unshaded squares to the number of shaded squares.​

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Number of shaded squares = 3
number of unshaded squares = 7
Required ratio = 7 / 3 = 7 : 3

Thus, the required ratio of the unshaded square to the shaded square is 7 : 3.

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:

66

Step-by-step explanation:

first you find the area of the rectangle

5*12=60

then you find the area of the triangle

to find the length of the dotted line you need to subtract 9 from 12 which is 3

to find the length of the line adjacent to the dotted line you need to subtract 5 from 9 which is 4

use the triangle area formula 3*4*1/2=6

add the areas of the triangle and the rectangle 60+6=66
