Which expression Is equivalent to x2-17x-60
Need work attached.
Answer:
Step-by-step explanation:
Find the roots of x² - 17x - 60
Quadratic formula
x = [17 ± √(17² – 4·1(-60))] / [2·1]
= [17 ± √529] / 2
= [17 ± 23] /2
= -3, 20
x² - 17x - 60 = (x+3)(x-20)
Answer:
(x+3)(x-20)
Step-by-step explanation:
x^2+3x-20x-60
x(x+3)-20(x+3)
= (x+3)(x-20)

1. 3x - 6
2. -9x + 3
3. -4x -8
Step-by-step explanation:
G(x) = 2/3 x - 6 switch x and y around and solve for y.
y = 2/3 x - 6
x = 2/3 y - 6
x + 6 = 2/3 y
3/2 x + 9 = y
Which measurement is closest to the area of the circle in square centimeters ? A. 31.4cm² B. 78.5cm² C.62.8² D.50.2cm²
Answer: it’s a
Step-by-step explanation: took the test got it right
The required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.
What is an area circle?The area of the circle is given by the pie times square of the radius.
Area of circle = πr^2
Here,
Let the radius of the given circle be r = 5 cm
Area of the circle = πr²
Substitute the value in the above expression,
Area of the circle = π 5²
Area of the circle = 78.5cm²
Thus, the required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.

Mr. Fry is building a fence around his pool.
•Length of the fence is 60 feet.
•Width of the fence is 30 feet.
How many yards of fence will Mr. Fry build?
Answer:
30 yards of fence
Step-by-step explanation:
First, convert 60 feet to yards and 30 feet to yards. Remember, 1 foot= 3 yards.
60/3= 20 yards
30/3= 10 yards
Then you add the length and the width of the fence (in yards) to find the total yards of fence.
20+ 10= 30 yards of fence

==========================================================
Explanation:
For each row, divide the earnings over the sales.
In row 1, we have 22/673 = 0.0327 approximately In row 2, we have 37/1298 = 0.0285 approximately In row 3, we have 101/3277 = 0.0308 approximately In row 4, we have 150/5180 = 0.0290 approximatelyAll of these decimal values have the following conversions to percentages
0.0327 = 3.27% 0.0285 = 2.85% 0.0308 = 3.08% 0.0290 = 2.90%If we add up those percentages and divide by 4, we get the average percentage
(3.27+2.85+3.08+2.90)/4 = 3.025
So the average percentage of these four is 3.025%
So for instance, if you made $1000 in sales, then 0.0325*1000 = 32.50 would be the estimated earnings.
A good estimate in my opinion is the equation c = 0.0325d since 3.025% converts to the decimal form 0.0325
Another method you could use is linear regression to help estimate. Though this method is a lot more complicated involving many more steps. It's better to use technology (eg: graphing calculator) if you go this route. The linear regression line is approximately y = 0.02896x + 2.00732; we can see the slope 0.02896 isn't too far off from 0.0325. Other forms of regression are possible as well.

Answer:
[tex]\boxed {\boxed {\sf b=60 \ meters}}[/tex]
Step-by-step explanation:
This is a right triangle because of the small square in the corner representing a 90 degree angle.
Therefore, we can use the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
Where a and b are the legs and c is the hypotenuse.
80 and b are the legs, because they form the right angle. 100 is the hypotenuse because it is opposite the right angle.
[tex]a=80 \\b=b \\c=100[/tex]
[tex](80)^2+b^2=(100)^2[/tex]
Solve the exponents.
(80)²=80*80= 6400 (100)²= 100*100= 10000[tex]6400+b^2=10000[/tex]
Solve for the unknown by isolating the variable. First, subtract 6400 from both sides.
[tex]6400-6400+b^2=10000-6400\\b^2=3600[/tex]
Take the square root of both sides.
[tex]\sqrt {b^2}= \sqrt {3600}\\b=60 \\b= 60 \ m[/tex]
The missing leg is 60 meters.

Market researchers were interested in the relationship between the price of bobbleheads and the demand of bobbleheads. Information was collected from a survey and used to obtain the regression equation ŷ = –0.227x + 50.455, where x represents the price of bobbleheads (measured in dollars) and ŷ is the predicted demand of bobbleheads (in units). What is the predicted demand of a bobblehead that has price of $6.00?
–1.362 units
49.093 units
51.817 units
195.837 units
Answer:
49.093
Step-by-step explanation:
Given the regression equation :
ŷ = –0.227x + 50.455
x represents the price of bobbleheads (measured in dollars)
ŷ is the predicted demand of bobbleheads (in units).
Preductwd demand ; when x = 6
ŷ = –0.227(6)+ 50.455
= 49.093

You purchase a t-shirt for $9.55 and a pair of jeans for 18.12 from Old Army at 7% sales tax.
How much change should you receive if you give the cashier two twenty-dollar bills?
Answer:
$10.39 is the change
Step-by-step explanation:
We start by calculating the total score
9.55 + 18.12 = 27.67
we now calculate the sales tax
This is 7% of the total
= 7% of 27.67
7/100 * 27.67
= $1.94
The total now comes;
1.94 + 27.67 = $29.61
The total was 2 * 20 = $40
The change was;
$40 - $29.61 = $10.39
