The figure can be composed in to one triangle and one rectangle and the area is 30 square feet.

Area of a two dimensional shape is the total region which is bounded by the object's shape.

Given is a figure.

We can divide the figure in to one triangle and one rectangle by drawing a vertical line.

Area of a rectangle = Length × Width

Here, length = 8 feet and width = 3 feet

Area of rectangle = 8 × 3 = 24 feet²

Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height

Base = 12 - 8 = 4 feet and height = 3 feet

Area of triangle = [tex]\frac{1}{2}[/tex] × 4 × 3 = 6 feet²

Total area = 24 feet² + 6 feet² = 30 feet²

Hence the area is 30 feet².

Answer:

200 patients

Step-by-step explanation:

120 =60% means that

2=1%

1% x 100 = 100%

2 x 100 = 200

200 total patients

120 Female

80 Male

Answer:

20% (pls mark me brainliest)

Step-by-step explanation:

1. you have to figure out what percentage each marble is by dividing 100 by the total amount of marbles 100 ÷ 16 = 6.25%

2. you then take that sum and you multiply it times seven because there are seven purple marbles, 6.25 x 7 = 43.75% which is the probability that you'll pick a purple marble.

3. you would then have 15 marbles so you would have to do step 1. again but with 15 substituted instead of 16, 100 ÷ 15 = 6.67%

4. after that you would do step 2. again, this time taking 6.67 and multiplying it by seven because of the seven orange marbles: 6.67 x 7 = 46.69%

5. since for this to work you would need to choose the purple one in the first place you need to figure out what 46.69% is out of 43.75%: 20.426875% which rounds down to 20%

Answer:

∠s + ∠y are complementary

∴ ∠s + ∠y = 90°

∠s = 4(∠y ) -100

s + y = 90

4y - 100 + y = 90

5y = 90 + 100

5y = 190

y = 38

Ans: y = 38°

Answer:

DB = 8

Step-by-step explanation:

Δ ADB and Δ BDC are similar so ratios of corresponding sides are equal, that is

[tex]\frac{DB}{DC}[/tex] = [tex]\frac{AD}{BD}[/tex] , substitute values

[tex]\frac{DB}{17.8-5}[/tex] = [tex]\frac{5}{BD}[/tex]

[tex]\frac{DB}{12.8}[/tex] = [tex]\frac{5}{BD}[/tex] ( cross- multiply )

DB² = 64 ( take the square root of both sides )

DB = [tex]\sqrt{64}[/tex] = 8

The length of segment DB is 8 units.

From the given right triangle we can deduce the following;

From the corresponding triangle rules, we can calculate the length of DB by considering the following ratios;

[tex]\frac{DB}{DC} = \frac{AD}{DB} \\\\DB^2 = AD\times DC\\\\DB^2 = 5 \times (17.8-5)\\\\DB^2 = 5 \times 12.8\\\\DB^2 = 64\\\\DB = \sqrt{64} \\\\DB = 8 \ units[/tex]

Thus, the length of segment DB is 8 units.

The expressions represented by the grid will be 0.6 x 4 and 0.4 x 6. The correct options are A and C.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that there is a grid showing the shaded boxes. The expression used to calculate the shaded boxes will be written below,

E₁ = 0.6 × 4

E₂ = 0.4 × 6

Hence, the expressions will be 0.6 x 4 and 0.4 x 6.

Answer:

y = x + 3

Step-by-step explanation:

The given graph indicates that the y-intercept of this line is 3 (that is, b = 3).  The y-intercept is also represented by (0, 3).  The graph also goes through (-3, 0).  The 'run' is the jump of the x-coordinate from -3 to 0, and thus is 3; the 'rise' is the jump of the y-coordinate from 0 to 3, and is thus 3.  Therefore, the slope of this line, m, is rise/run, which here is m = 3/3, or just 1.

The slope-intercept equation y = mx + b is therefore y = x + 3.

I would suggest you write out your objective before attempting problem solution.  In this case, write out "find the equation of the line shown in this graph, in slope-intercept form."
