1 Serek is showing how to model the area
formula of a triangle
1) Original triangle
2) Create a congruent triangle.
Rotate it then join it to the original
triangle, forming a parallelogram.
3) Decompose the parallelogram
into a right triangle and a trapezoid.
4) Rearrange the triangle and
trapezoid to form a rectangle.
Which of these steps will identify the area
of the original triangle?
A Find the total area of the trapezoid
B Find half the area of the rectangle
C Find half the area of the trapezoid
D Find the area of the shaded triangle
5.80
Answer:
Find half the area of the rectangle
Step-by-step explanation:
Given
See attachment for the Serek's steps
Required
Which can be used to determine the area of the original triangle
To do this, we simply analyze each step.
At step 2, where he joined two congruent triangles to form a parallelogram.
Half the area of the parallelogram will give the area of the original triangle (since both triangles are equal)
At step 3, where he decomposed the parallelogram to a trapezoid and a right triangle.
Half the sum of the areas of the resulting shapes (trapezoid and right triangle) will equal to the area of the original triangle but half the area of each shape will not amount to the area of the original triangle
At step 4, where the right triangle and the trapezoid are merged to form a rectangle.
The area of the rectangle will equal to the area of the parallelogram in step (2).
So, half the area of the rectangle will equal to the area of the triangle.
Hence, (b) is correct

A. 0, 8, 16, 24, ...
B. 22, 14, 6, -2, ...
C. -22, -30, -38, -46,...
D. -14, -6, 2, 10, ...
Answer:
D. -14, -6, 2, 10, ...
Step-by-step explanation:
Plug in the values for x.
8(1) - 22 = x
8 - 22 = x
-14 = x
8(2) - 22 = x
16 - 22 = x
-6 = x
8(3) - 22 = x
24 - 22 = x
2 = x
8(4) - 22 = x
32 - 22 = x
10 = x

Answer:
8.31
Step-by-step explanation:
Using the Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
[tex]10^2+b^2=13^2[/tex]
[tex]100+b^2=169[/tex]
[tex]b^2=69[/tex]
[tex]b = \sqrt{69}[/tex]
[tex]b = 8.306623863[/tex]
The side length for [tex]x[/tex], rounded to the nearest hundredths, would be 8.31.
The length of a rectangle is 5 units longer than its width, w. Select the expression that represents the perimeter of the rectangle.
Answer: The expression that represents the perimeter of the rectangle is given as
Perimeter= 4x +10
Step-by-step explanation:
Perimeter= 2l+2w =2( l+w)
Let the width be =x
And Length=x+5
So that the Perimeter =2l+2w becomes
Perimeter =2x +2(x+5)
Perimeter =2x+2x+10
Perimeter= 4x +10

Triangle DEF has coordinates D(3, 4), E(4, 1), and F(1, -2). If the triangle is
dilated by a scale factor of 4, what are the coordinates of E?
Answer:
Hello! answer: coordinates of E' are (16, 4)
Step-by-step explanation:
4 × 4 = 16 4 × 1 = 4 therefore the new coordinates are (16, 4)
The coordinate of E after dilation is (16, 4).
What is a triangle?It is a two dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Triangle DEF has coordinates:
D = (3, 4)
E (4, 1)
F = (1, -2)
The coordinates are dilated with a scale factor of 4.
This means,
Multiply all the coordinates by 4.
Now,
D = (3 x 4, 4 x 4) = (12, 16)
E (4 x 4, 1 x 4) = (16, 4)
F = (1 x 4, -2 x 4) = (4 , -8)
Thus,
The coordinate of E is (16, 4).

Answer:
The measurement that is closest to the total surface area of the box is 1,507.96 [tex]in^2[/tex].

Look at the pentagonal numbers. Use finite differences to determine which function represents the pattern.
f(x) = 1.5x - 0.5x
f(x) = 1.5x^2 + 1.5x
f(x) = 1.5x^2 - 0.5v
f(x) = 0.5x^2 + 0.5x
Answer:
f(x) = 1.5x - 0.5x
Step-by-step explanation:
The function of the pattern represented by the pentagonal numbers is the sum of three triangular numbers.
The triangular number general formula
x (x + 1) / 2
For example,

Fred paints houses. He was paid 475 dollars for a job that took 19 hours. His second job took 26 hours and he was paid 720. He was paid 1180 for his 3rd job. How long did this job take?
Answer:
Total time taken to complete the job is 26 hours
Step-by-step explanation:
Fred's First Job
Total amount paid = 475 dollar
Total hours of work = 19 hours
Charge per hour = 475/19 = 25 dollars per hour
Fred's second job
Total amount paid = 720 dollar
Total hours of work = 26 hours
Charge per hour = 720/26 = 27.69 dollars per hour
Fred's third job
Amount paid = 1180
When amount paid was 720, charge per hour was 27.69
When amount paid is 1180, charge per hour is (27.69/720) * 1180 = 45.38
Total time taken to complete the job = 1180/45.38 = 26 hours

Help me with this one. I’m stuck with it since an hour and a bit more.
Answer:
1) 5 : 7 : 8.75
2) Happy = 168 . Juma = 210
3) Rima = 17800 . Happy = 24920 . Juma = 31150
Step-by-step explanation:
1) 5 : 7 : 8.75
Ratio Rima to Happy = 5:7
Ratio Happy to Juma = 4:5
7/4 = 1.75
1.75 x 5 = 8.75
Ratio = 5 : 7 : 8.75
2) Happy = 168 . Juma = 210
Ratio = 5 : 7 : 8.5
120 / 5 = 24
Happy = 24 x 7 = 168
Juma = 24 x 8.75 = 210
3)17800 : 24920 : 31150
5 + 7 + 8.75 = 20.75
73870 / 20.75 = 3560
3560 * 5 = 17800 = Rima
3560 * 7 = 24920 = Happy
3560 * 8.75 = 31150 = Juma

Solve In(5x + 3) = 2.5
Answer:
[tex]x=\frac{e^{2.5}-3}{5}[/tex]
Step-by-step explanation:
Let y = 5x + 3
Then we get
㏑(y) = 2.5
Using exponentiation,
[tex]e^{lny} = e^{2.5}\\\textrm{But }e^{lny} \textrm{ is simply y (log rule)}\\\textrm{So we get}\\y = e^{2.5}\\\\\\\textrm{Substituting for y we get}\\\\5x + 3 = e^{2.5}\\x = (e^{2.5} - 3)/5\\[/tex]
This works out to x = 1.83649879
