Answer:
2t - 7
Step-by-step explanation:
We have the expression 2(t - 4) + 1 and are asked to see which is the equivalent.
To solve, we need to first get rid of the parenthesis, which is done by distributing the number outside of the parenthesis to the numbers inside of the parenthesis :
2(t - 4) + 1
(2 * t) - (2 * 4) + 1
2t - 8 + 1
Combine like terms :
2t - 7

Answers
Answer:
30degrees
Step-by-step explanation:
On a unit circle, the terminal point of theta is (sqrt 3/2, 1/2). What is theta if 0° <_theta< 360°?
From the coordinate given;
x = √3/2
y = 1/2
theta = arctan(y/x)
theta = arctan(1/2÷√3/2)
theta = arctan(1/2 * 2/√3)
theta = arctan(1/√3)
theta = 30degrees
Hence the value of theta is 30degrees
On a unit circle, the terminal point of θ is (√3/2, 1/2). What is θ if 0° ≤ θ < 360°?
θ = 30°

There is a sales tax of $6 on an item that costs $64 before tax. The sales tax on a second item is 8.25. How much does the second item cost before tax?
Answers
Hence for the item that costs $1 before tax the sales tax is $(6/64), by the rule of proportions or unitary method
Hence for the item that costs $100 before tax the sales tax is $[100*(6/64)], by the rule of proportions
which is = $75/8 or $9.45
Therefore, the item having a Sales tax of $9.45 or $75/8 costs $100 before tax
thus the item having a Sales tax of $1 costs $[(100*8)/75] before tax, by the rule of proportions or unitary method
thus the item having a Sales tax of $8.25 costs $[(100*8*8.25)/75] before tax, by the rule of proportions
which is = $88

Mr. Hawkins is covering a wall with wallpaper. The room measures 14 feet by 12 feet in a rectangular shape. Each square foot or wallpaper costs $2.90. What is the cost of adding wallpaper to the room?
Answers
Answer:
The total cost of adding wallpaper to the room is 487.20
Answer:
The total cost of adding wallpaper to the room is $487.20
Step-by-step explanation:
Basically, how I got the answer is:
1. The shorter sides of the rectangle are 12 and the longer sides are 14.
2. The formula for a rectangle is A = l x w. The "l" means length and the "w" means width. 14 is the length and 12 is the width. So you should now have A = 14 x 12. If you multiply 14 by 12, you will get 168.
3. Since 1 square foot of carpet costs $2.90, then you should multiply by 168, which will give you $487.20 and that's pretty much it.
Hope this helps! :)
The length of a rectangle is 5 units longer than its width, w. Select the expression that represents the perimeter of the rectangle.
Answers
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

What is the value of a in the equation 0.75 (a - 2) = 5.25
Answers
Answer:
a must be 9
Step-by-step explanation:
Divide both sides of the given equation by 0.75, to isolate (a - 2):
a - 2 = 5.25/0.75 = 7
Then a - 2 = 7, and so a must be 9.

The length of line segment FG is greater,than,less than,equal to.
The perimeter of pentagon CDEFG is less then greater than or equal to the perimeter of pentagon C'D'E'F'G.
Answers
Answer:
The length of line segment FG is equal to the length of F'G'
The perimeter of pentagon CDEFG is equal to the perimeter of pentagon C'D'E'F'G.
Step-by-step explanation:
Given
CDEFG and C'D'E'F'G
Translation: 7 units up and 5 units left
Solving (a): Segment FG and F'G'
When a shape is translated, the resulting image will have the same lengths as the original image (i.e, translation does not change measurements)
Hence:
[tex]FG = F'G'[/tex]
Solving (b): Perimeter CDEFG and C'D'EF'G'
In (a), we established that lengths do not change during translation;
Hence:
The perimeter of the CDEFG and C'D'EF'G' will remain the same

represent 3/4 and 8/9 on a number line
Answers
Answer:
Step-by-step explanation:
3/4 and 8/9 both lie between 0 and 1. Their LCD is 36.
Thus, 3/4 = 27/36 and 8/9 = 32/36.
Dividing the number line between 0 and 1 into 36 equal lengths, plot a dot at the 27th such mark and then another dot at the 32nd mark.
This clearly shows that 32/36 is larger than 27/36.
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
Answers
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,
The sequence
1, 3, 6, 10

_____________________________
The pentagonal numbers
The sequence:
1, 5, 12, 22, 35
As shown in the picture can be divided into three triangles
Triangle 2
x (x + 1) / 2
Triangle 1 and 3 (they are triangles one unit smaller than 2)
n (n + 1) / 2
n= x-1
Replacing n
(x-1) ((x-1) + 1) / 2
(x-1) (x) / 2
(x-1) x / 2
______________
Function represents the pattern
Triangle 2 + (Triangle 1 + Triangle 3)
Triangle 1 = Triangle 3
So then,
Triangle 2 + 2* Triangle 1
x (x +1) /2 + 2* (x -1) x/2
Rearranging
0.5 x (x +1) + x(x -1)
0.5x^2 + 0.5x + x^2 -x
(0.5 x^2 + x^2) + (0.5x -x )
1.5 x^2 - 0.5 x

Answers
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
