Answer:

A: 0.3318 m^2  P: 2.66

Step-by-step explanation:

The perimeter is only adding each of the side lengths, so that's not much of an issue. The equation for the area of a triangle is A = (b x h)/2, with "b" being the base length and "h" representing the triangle's height. We must first multiply the base and height, 0.84 x 0.79. This makes 0.6636 which we will then divide by 2. Our area is now proven to be 0.3318 square meters.

Answer:

y = 1/2x + 0.5

or

y = 1/2x + 1/2

Step-by-step explanation:

y = mx + b

b is y-intercept:

when x = 0, y = 0.5 (when the line cross the vertical (y) axis of the graph)

the point is (0, 0.5) so b = 0.5

m is slope:

slope = rise / run

rise = 1

run = 2

for every 2 x values, y increase by 1

slope (m) = 1/2

The line perpendicular to y - 3 = 4(x+2) is y-3 = -1/4(x+2)

Two lines are said to be perpendicular if the product of their gradient is -1.

which means m1 x m2 = -1

Analysis:

y - 3 = 4(x+2)

y = 4x + 8+3

y = 4x + 11    m1 = 4

so m1 x m2 = -1

m2 = -1/4

so from the options, the equation with a gradient x = -1/4 is C, y-3 = -1/4(x+2)

In conclusion, the line that would be perpendicular to y - 3 = 4(x+2)

Answer:

The equation to find Hannah's age is  2h - 2 = 92.

This yields Hannah's age as 47 years.

Step-by-step explanation:

Let h = Hannah's age.

Hannah is older than her sibling, and their ages are consecutive odd integers. Therefore, h = an odd number and the sibling's age =  h-2.

The sum of their ages is 92, therefore

h + (h-2) = 92

2h - 2 = 92

2h = 94

h = 47 years

B:Similar :SAS

Step-by-step explanation:

The Angle-Side (SAS) Similarity Theorem states that  If an angle of one triangle is congruent to an angle of a second triangle and the lengths of the sides including these angles are proportional, then the triangles are similar.

In the given triangles <B=<E= 40 °

Or,

Hence triangle ABC~ Triangle DEF by SAS similarity theorem.

Give brainliest :)

Option B is correct, by SAS postulate the triangles ABC and DEF are similar.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

ABC and DEF  are similar triangle as the corresponding angles are congruent and the corresponding sides are in proportion .

If two sides and the included angle in one triangle are congruent to two sides and the included angle in another triangle, then the two triangles are congruent.

Hence, by SAS postulate the triangles ABC and DEF are similar.

60.7%

17:28

11/28

39.3%

11:28

Difference:  [tex]\frac{3}{14}[/tex]

Explanation:

A fraction can be turned into a percent by dividing the numerator by the denominator and multiplying the result by 100%.

For example:

17/28 = 0.607

0.607 * 100% = 60.7%

A fraction can be turned into a ratio by writing it like this:

numerator:denominator

For example:

11/28

11:28

To find the difference between 2 fractions with the same denominator, simply subtract the 2 numerators.

For example:

[tex]\frac{17}{28} - \frac{11}{28}[/tex]

You subtract 11 from 17, then put the resulting 6 in the fraction with the same denominator. This results in [tex]\frac{6}{28}[/tex] which can be simplified to [tex]\frac{3}{14}[/tex].

Answer:

50 calories

Step-by-step explanation:

One serving of a certain brand of microwave popcorn provides 150 calories, 90 of which are from fat. The fraction that comes from fat:

= 90/150 = 3/5

One serving of a certain brand of low-sodium pretzels provides 120 calories, 12 of which are from fat. The fraction that comes from fat here:

= 12/120 = 1/10

The fat that are provided by a 100 calorie serving of the microwave popcorn would be:

= 3/5 × 100

= 60

The fat that are provided by a 100-calorie serving of the pretzels would be:

= 1/10 × 100 = 10

The difference from fat that are provided by a 100 calorie serving of the microwave popcorn than are provided by a 100-calorie serving of the pretzels would be:

= 60 - 10

= 50 calories

The number of hours worked in a week where her earnings would be $210 is 20 hours.

Direct variation is when two variables move in the same direction. If one variable increases, the other variable increases. Sadie's earnings increase with hours worked. This is a direct variation.

Hours worked = Total earnings / earning per hour

The quadrilateral is a trapezoid and the area of the quadrilateral is 85.04 square units

The vertices are given as:

A:(-2, 3) B:(4, -6) C:(10, 2) D:(6, 8)

Next, we plot the vertices (see attachment)

From the attached graph, we can see that the quadrilateral is a trapezoid

From the plot, we have the following features:

Height: AD

Parallel sides: CD and AB

Calculate the lengths using:

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

So, we have:

[tex]AD = \sqrt{(-2 -6)^2 + (3 -8)^2}[/tex]

[tex]AD = \sqrt{89}[/tex]

[tex]CD = \sqrt{(10 -6)^2 + (2 -8)^2}[/tex]

[tex]CD = \sqrt{52}[/tex]

[tex]AB = \sqrt{(-2 -4)^2 + (3 +6)^2}[/tex]

[tex]AB = \sqrt{117}[/tex]

The area is then calculated as:

Area = 0.5 * (CD + AB) * AD

This gives

Area = 0.5 * (√52 + √117) * √89

Evaluate

Area = 85.04

Hence, the area of the quadrilateral is 85.04 square units
