Answer:
2(t-3) ^2 = 72
(t - 3)^2 = 36
t - 3 = 6 or t - 3 =-6
t = 6+3 = 9. or t =-6 +3 = -3
t = 9 or -3
We have that
The Value of t is
t=9
From the question we are told
2 (t -3) ² - 72=0
In Answering the Question we must follow these few steps
Firstly we must make t the subject of the FormulaSecondly,We perform the necessary arithmeticFinally,The value of t will be gottenGenerally the derivation of t is mathematically given as
[tex](t-3)^2=\frac{72}{2}\\\\t-3=\sqrt{\frac{72}{2}}\\\\t-3=6\\\\t=9[/tex] [Firstly we must make t the subject of the Formula

A model car kit is built to a scale of 1cm : 32cm. The length of the model car is 13 cm. What is the length of the actual car?
Answer:
I'm late but the answer is 416 cm
Step-by-step explanation:
If every cm of the model car equals 32 centimeters of the actual car, you would just multiply 13 by 32 and get 416
simplify the expression 3(5x-3)-2x+4
Answer:
=13x-5
Step-by-step explanation:
Answer:
13x-5
Step-by-step explanation:
You would use distributive property to get 15x-9 and then the -2x+4.
Distributive property works for the numbers in the parenthesis and you multiply the 5x and the -3 by 3.
Then, you would do your basic math to get 13x-5
Cara has two pieces of ribbon, one 15 inches long and the other 20 inches long. To decorate an album, she wants to cut them up to produce many pieces of ribbon that are all of the same length, with no ribbon left over. What is the greatest length, in inches, that she can make them?
Answer:
5 inches
Step-by-step explanation:
Given that :
There are two pieces of ribbon with length:
15 inches and 20 inches
To cut ribbon into equal sizes with no ribbons left ; the greatest length in inches of the ribbon would be :
Calculate the greatest common factor of both lengths : 15 inches and 20 inches
____15___20
_5__ 3___4
OR
Find the factors of 15 and 20 and pick the greatest common to both
15 : 1, 3, 5, 15
20 : 1, 2, 4, 5, 10, 20
Greatest factor common to both = 5
Hence the greatest length she can cut the ribbons into without any leftover is 5 inches

Answer:
$163
Step-by-step explanation:
Bob worked 26 hours and earn $7 per hour. Multiply 26 with 7:
26 x 7 = 182
Bob made a total of $182 last month.
Bob then spent $19. Subtract 19 from the total earned:
182 - 19 = 163
Bob has $163 left.
~
Answer:
He has $163 dollars left
Step-by-step explanation:
Because first we needed to find out how much did he make in 26 hours, 29 (hours) x $7 (per hour) = $182
Then he spent $19, $182 (how much he made in 26 hours) - $19 (how much he spent) = $163
Does anyone know how to find this I'm studying and me and my family don't understand! I only need help on #17
Answer:
4
Step-by-step explanation:
Hi so basically you just convert the inches to decimals so
0.5 x 0.5 x 0.25 = 0.0625
Use a calculator to convert 0.0625 into fraction which is [tex]\frac{1}{16}[/tex]
Multiply [tex]\frac{1}{4}[/tex] by 3 = [tex]\frac{1}{64}[/tex]
Then multiply [tex]\frac{1}{16}[/tex] by [tex]\frac{1}{64}[/tex] = 4

Answer:
length: 2 cubeswidth: 1 cubeheight: 2 cubesvolume: 4 cubesStep-by-step explanation:
We assume in this context that a "1/4 unit cube" is a cube that is 1/4 unit on a side. When the "unit" is "inches", then the "1/4 unit cube" is a cube that is 1/4 inch on a side.
It should not take too much thought to realize that a dimension that is 1/2 = 2/4 inches will be 2 cubes long. A dimension that is 1/4 inch will be 1 cube long.
Then the 1/2 by 1/2 by 1/4 prism will have dimensions in "cubes" of ...
2 cubes × 2 cubes × 1 cube
As with any rectangular prism volume calculation, the volume is the product of the dimensions:
V = LWH = (2)(1)(2) = 4 . . . cubes
_____
For this prism, it should not be too difficult to see that if you stack 2 smaller cubes on top of two smaller cubes, the overall dimensions of that will be 1/2 inch wide by 1/2 inch high by 1/4 inch deep.
_____
Additional comment
Which dimensions you call length, width, and height are irrelevant, as each is interchangeable with any other in the formula for volume. Here, I have elected to call height the vertical dimension, length the left-right horizontal dimension, and width the front-back dimension. You are welcome to choose an assignment of names to dimensions that suits your taste (or that of your grader).

Find the next term of the square 16,9,2,-5....
Answer:
- 12
Step-by-step explanation:
There is a common difference between consecutive terms in the sequence.
9 - 16 = 2 - 9 = - 5 - 2 = - 7
Thus to find the next term subtract 7 from the previous term, that is
- 5 - 7 = - 12

find the rate of interest when principal rs 6400 SIMPLE INTEREST RS 768 and time 2 years
Answer:
rate of interest is 6 percent per annum.
Step-by-step explanation:
Formula for simple interest is given
SI = p*r*t/100
where
SI is simple interest
p is principal
r is the rate of interest
t is the time
_______________________________
Given
p = 6400
SI = 768
t = 2 years
r we have to find
lest sue the above formula and plug the given value in it
768 = 6400*r*2/100
=> 768 = 128r
=> r = 768/128 = 6
Thus, r = 6%
thus, rate of interest is 6 percent per annum.

Sally received a $30 gift card that could be used to download songs. After she downloaded 7 songs , she had $15 remaining on her gift card. If each song costs the same amount to download, what is the cost of one song?
Answer:
Step-by-step explanation:
2 dalliers and 14 cents
Answer:
$2.14285714286 or $2.14
Step-by-step explanation:
This is quite simple.
#1. Take-away $15 from $30 because "$15 remain"ed.
#2. Then you get $15 dollars and divide that by 7, because she used the "same amount to download" each song so you divide 15 among 7 equally.
#3. There you go! You have the answer! it's: $2.14285714286 or $2.14 if simplified.

Charlie runs a book rental business. He currently charges $3 per book and rents out an average of 38 books a day.
According to a study, for every 50C increase in rental price, the average business can expect to lose 4 rentals a day.
Complete the equation that models this scenario, where b(x) is the revenue generated and x is the number of 50 price increases.
b(x)= x + x+ [
Answer:
b(x) = -2X² + 19X + 114
Step-by-step explanation:
b(x) = total revenue generated per day
total revenue formula ⇒ b(x) = price x quantity
price = $3 current price + 0.5X price increase = 3 + 0.5X
quantity = 38 current quantity sold - 4 books per X = 38 - 4X
b(x) = (3 + 0.5X) · (38 - 4X)
b(x) = 114 -12X + 19X - 2X²
b(x) = -2X² + 19X + 114

Answer:
2x + 200 = 6x + 120
Step-by-step explanation:
Super-Clean house cleaning company: 2x + 200
Power Bright: 6x + 120
Now, they have to be equal because we are trying to find the equation for total charges.
So, your equation would be 2x + 200 = 6x + 120.
Hope this helps!
Answer:
Step-by-step explanation:
Let the number of linear feet = x
Let the total cost = y
Condition One
y = 200 + 2x
Condition Two
y = 120 + 6x
Now you want the ys to be the same.
200 + 2x = 120 + 6x
