Step-by-step explanation:
1/2bh is how you find the area of a triangle ! :)
This means that for both triangles, the area is 2 times the height, 9, then multiplied by one half. The area is 9 for both the left and right triangle.
The area of the rectangle is the product of the two lengths: 9 and 12, which is 108.
This means that the area of the entire trapezoid is 126. :D

Answers
Answer:
Step-by-step explanation:
By using the Pythagorean theorem:
b^2+3^2=5^2
b^2+9=25
b=sqrt (25-9)
b=sqrt(16)
b=4
=> 4^2+7^2=c^2
16+49=c^2
65=c^2
=>c=sqrt(65)

Make x the subject
x=5y-4...(3)
Put Eqn(3) into Eqn(2)

15y-12-y=16
14y-12=16
14y=16+12

A tree is 4 ft 2 in. Tall. To find the height of a tower, the shadow of the tree and the shadow of the tower were measured. What is the height h of the tower?.
Answers
Answer:
20 ft
Step-by-step explanation:
Convert all measurements to a single unit, inches, using the fact that 1 foot is equal to 12 inches.
ZY=(24⋅12) in.
Simplify.
ZY=288 in.
RH=(4⋅12) in.+2 in.
Simplify.
RH=50 in.
RQ=(5⋅12) in.
Simplify.
RQ=60 in.
ZX¯¯¯¯¯ and QH¯¯¯¯¯¯ are parallel because the rays of the Sun that form them are parallel. Therefore, the angles they form with the ground
are congruent: ∠Z≅∠Q.
∠Y≅∠R by the Right Angle Congruence Theorem.
Therefore, by the Angle-Angle Similarity △ZXY~△QHR.
Find XY. Set up a proportion with the lengths of the known sides and the unknown length (height of the tower).
ZYQR=XYHR
Substitute the values.
28860=h50
Cross multiply.
60h=50(288)
Simplify.
60h=14400
Divide both sides by 60.
h=240
The height of the tower is 240 in., or 20 ft.
Which conclusion can best be made from this scatter plot?
Answers
According to the graph, it can be inferred that the most accurate conclusion is that the older the age, the percentage of 3 points is lower (option c).
What does the graph show?The graph shows the relationship between the percentage of 3 points and different ages from 20 years to 50 years. In general, from twenty to 35 are the most points that refer to the percentage of 3 points.
What conclusion can be obtained?According to the graph, it can be inferred that the most appropriate conclusion for this graph is that the older the age, the percentage of 3 points decreases because most of the points are in a range of 20 to 35 years of age.
After 40 years, there are only 3 points, which indicates a very significant decrease in the percentage of points at older ages.

The canopy of a parachute is a semicircle with a radius of 13 feet.
A company that is making parachutes for a Fourth of July celebration wants each parachute to be made from equal parts of red, white, and blue fabric.
What is the surface area of a semicircle?The area of a semicircle is half of the area of the circle.
The first step is the surface area of the semicircle.
The surface area of a circle is;
[tex]\rm Surface \ area=\pi r^2\\\\Surface \ area=3.14 \times 13^2\\\\Surface \ area =530.929[/tex]
Since the semicircle, we divide this by 2.
S.A of the parachute is;
[tex]\rm =\dfrac{530.929}{2}\\\\= 265.4645[/tex]
To get the fabric is needed for each color we divide this by 3.
The fabric needed for each color is;
[tex]\rm= \dfrac{265.4645}{3}\\\\=88.5[/tex]
Hence, the 88.5 ft² fabric of each color will be needed to make a single parachute canopy.

The time,
T
(seconds), it takes for a pot of water to boil is proportional to the amount,
A
(litres), of water.
It takes 210 seconds to boil 2.5 litres of water.
Work out how long it takes (to the nearest second) to boil 2.8 litres
Answers
Answer:
2.5 liters = 2500 grams
210 ÷ 2500 = 0.084
2.8 liters = 2800 grams
2800-2500 = 300
300×0.084 = 25.2
25.2 + 210 = 235.2 to boil 2.8 liters

What is the sum of the given polynomials in standard form? (x2 – 3x) (–2x2 5x – 3).
Answers
Sum of standard form polynomials means adding the terms of same variable. The sum of the given polynomial in standard form is,
[tex]-x^2+2x-3[/tex]
What is polynomial equation?A polynomial equation is the equation in which the unknown variable is one and the highest power of the unknown variable is n.
Here, n is any real number.
In the polynomial equation the the terms are added or subtracted from each other only when the power of the variable is same.
Given information-
The first polynomial equations given in the problem is,
[tex](x^2 - 3x)[/tex]
The second polynomial equations given in the problem is,
[tex](-2x^2+ 5x - 3).[/tex]
To find the sum of these two polynomials, add the two terms together as,
[tex](x^2 - 3x)+(-2x^2+ 5x - 3)[/tex]
Let the result of the sum is [tex]f(x)[/tex]. Thus,
[tex]f(x)=(x^2 - 3x)+(-2x^2+ 5x - 3)\\f(x)=x^2-3x-2x^2+5x-3[/tex]
Separate the similar power variable as,
[tex]f(x)=(x^2-2x^2)+(-3x+5x)-3\\f(x)=-x^2+2x-3[/tex]
Thus the sum of the given polynomial in standard form is,

if you are diving from a diving board that is 20 feet in the air, into a pool. When jumping into the pool, you touch the bottom in the 10-foot section of the pool. How far did you fall from the diving board to the bottom of the pool? (sentence required)
Answers
Answer: 30 feet
Explanation:
Draw a vertical number line.
Mark +20 or simply 20 which is the starting position at the diving board. The value 0 on the number line is the water's surface. The position -10 is the portion 10 feet at the bottom of the pool.
Going from 20 to 0 is 20 feet. Then going from 0 to -10 is another 10 feet.
Overall, you travel 20+10 = 30 feet.
