40x24/2=384
2000+384=2384
Answer:
2384
Step-by-step explanation:
1. Approach
To solve for the area of the given figure, divide the figure up into two parts. This will ensure that one can find the area of each individual part, and then add the two resulting areas up to find the total area of the figure. One can split this figure into a rectangle, and a triangle.
2.Find the area of the rectangle
The rectangle will have the following dimensions,
(40) x (50)
To find the area of a rectangle, one will use the following formula,
(length) * (width) = (area)
Therefore, the area is the following,
(40) * (50) = 2000
3.Area of the triangle
3a. Approach
To find the area of a triangle, one will use Heron's formula. Herons' formula states the following,
[tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
Where (s) is the semi-perimeter or half of the perimeter, and (a), (b), and (c) are the sides of the triangle. This requires that one knows all of the sides of the triangle.
3b. Find the unknown side and semi-perimeter
It is given that the triangle is right indicated by a box around one of the angles), thus one can use the Pythagorean theorem to find the length of the unknown side. The Pythagorean theorem states the following,
[tex]a^2+b^2=c^2[/tex]
Where (a) and (b) represent the legs, the sides adjacent (next to) the right angle. Moreover, (c) represents the hypotenuse or the side opposite the right angle. Substitute in the given values and solve for (b),
[tex](40)^2=(24)^2+(b)^2\\[/tex]
Simplify,
[tex]1600=576+b^2[/tex]
Inverse operations,
[tex]1024=b^2\\\sqrt{1024}=b\\32=b[/tex]
Add up all of the sides of the triangle and divide by (2) to fin the semi-perimeter,
[tex]\frac{a+b+c}{2}\\\\=\frac{20+24+32}{2}\\\\=48[/tex]
3c. Find the area of the triangle
Substitute into Heron's formula,
[tex]\sqrt{s(s-a)(s-b)(s-c)}\\\\=\sqrt{48(48-32)(48-40)(48-24)}\\\\=\sqrt{48(16)(8)(24)}\\\\=\sqrt{147456}\\\\=384[/tex]
Add the area of the rectangle and triangle together to find the answer,
384 + 2000
= 2384

Answer:
[tex]x = \frac{22}{3}[/tex]
Step-by-step explanation:
Since both CB and ED intersect AD perpendicularly, we can say they are parallel and that ΔACB is similar to ΔAED from Thales intercept theorem. Now, we can set up a proportion from the definition of similar triangles:
[tex]\frac{AB}{AD} = \frac{BC}{DE}[/tex]
We can say that AD = AB + BD(segment addition postulate) and substitute to get AD = 11. Now we can plug in the numbers we have to the proportion:
[tex]\frac{6}{11} =\frac{4}{x}[/tex]
We can cross-multiply to get:
[tex]6x = 44[/tex]
and divide by 6 to get

Which model best represents the data?
y = 47(1.191)x
y = 34(1.204)x
y = 26.9x – 1.3
y = 27x – 4
Answer:
Y=26.9x-1.3is the answer
Step-by-step explanation:
The best model represents y = 26.9x – 1.3
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
As, the data given about productivity is well defined by y = 26.9x – 1.3
As, we have 4 functions so by putting the values we get
x A B C D
2 66.66 49.3 52.5 50
4 94.57 71.44 106.3 104
6 134.14 103.57 160.1 158

10 269.91 217.64 267.7 266
12 382.85 315.5 321.5 320.
So, the most accurate is (C)y = 26.9x – 1.3.

consider this equation tan(theta)=-5/3
if theta is an angle in quadrant II what is the value of sin(theta)
Answer:
B 5√34 / 34
Step-by-step explanation:
tan ∅ = opp/adj
In quad II
tan ∅ = 5 / (-3)
---------------------
hyp^2 = 5^2 + (-3)^2
hyp^2 =25 + 9 = 34
hyp = √34
---------------------------
sin ∅ = opp/hyp
sin ∅ = 5/√34
Rationalizing
sin ∅ = 5√34 / 34
Consider this equation [tex]tan(\theta)=-5/3[/tex]. if theta is an angle in quadrant II the of [tex]sin \theta = \dfrac{5\sqrt{34}}{{34} }[/tex].
What are the trigonometric ratios?Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.
In a right-angled triangle, two such angles are there which are not right-angled(not of 90 degrees).
The slanted side is called the hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.
Consider this equation
[tex]tan(\theta)=-5/3[/tex]
B 5√34 / 34
if theta is an angle in quadrant II what is the of sin(theta)
[tex]tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}[/tex]
In quadrant II
tan ∅ = 5 / (-3)
[tex]hyp^2 = 5^2 + (-3)^2\\hyp^2 =25 + 9 = 34\\hyp = \sqrt{34}[/tex]
[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}[/tex]

Solve -7g - 2 = - 30. Show your steps.
Answer:
g = 4
Step-by-step explanation:
-7g - 2 = -30
Add 2 to both sides to get:
-7g -2+2 = -30+2
which is equal to:
-7g = -28
now divide both sides by -7 to get the value of g which is:
g = -28 / - 7
--> g = 4
Answer:
g = 4
Step-by-step explanation:
First you can add 2 to both sides to isolate the x term:
-7g -2 = -30
+2 +2
-7g = -28
Now, you can divide by -7 both sides to find g,
-7g = -28
÷ -7 ÷ -7
g = 4

The measures of the angles of a triangle are shown in the figure below. Solve for x.
Help please explanation and thank you!
Answer:
D
Step-by-step explanation:
A: The sum of Y and H is +. If the scale is correct, this is not true. Y is further away from 0 than H is. Suppose H = 5 and Y = -7. Then Y + H = 5 + -7 = - 2
B: E and Y area both minus. The minus signs cancel. Therefore the answer will be + B is wrong.
C: H>0 and E<0. A negative times a positive is a negative not a positive. C is wrong
D: A - H Suppose A = 2 and H = 5 . Then A - H = 2 - 5 which is - 3
This is your answer.
The reason is that H is further from the 0 than A is.

Roy made a pizza that is 12 inches in diameter. He knows he can eat about 84.8 in, at what angle should Roy cut the pizza in radians? Round your answer to the tenths place.
Answer:
Cutting angle in radian θ = 3π / 2
Step-by-step explanation:
Given:
Diameter of pizza = 12 inch
He can eat = 84.8 inch²
Find:
Cutting angle in radian
Computation:
Radius of pizza = Diameter of pizza / 2
Radius of pizza = 12 / 2
Radius of pizza = 6 inch
Area of sector = [θ/360][πr²]
Area of sector = [θ/360][(π)(6)²]
84.8 = [θ/360][(π)(36)]
θ = 270°
θ = 270[π/180]
θ = 27π / 18
Cutting angle in radian θ = 3π / 2

|x+1|=|2x-6|
Answer:
x = 5, and/or x= - 7/3
Step-by-step explanation:
|x+1|=|2x+6|
We know eitherx+1=2x+6orx+1=−(2x+6)
x+1=2x+6(Possibility 1)
x+1−2x=2x+6−2x(Subtract 2x from both sides)
−x+1=6
−x+1−1=6−1 (Subtract 1 from both sides)
−x=5
(Divide both sides by -1)
x=−5
x+1=−(2x+6)(Possibility 2)
x+1=−2x−6(Simplify both sides of the equation)
x+1+2x=−2x−6+2x(Add 2x to both sides)
3x+1=−6
3x+1−1=−6−1(Subtract 1 from both sides)
3x=−7
Divide both sides by 3
