The product of two consecutive integers is 72. Write a quadratic equation to find the integers, and then solve it.
Answer:
9 x 8
Step-by-step explanation:
Answer:
ok so basically what you do is since you know they are consecutive numbers, one is x and the other is x+1. Now when you multiply x and x+1 you get 72 , so this basically turns into a quadratic where x(x+1)=72. Thus,X^2+x=72. subtract 72 from both sides- x^2+x-72=0. Then you can solve for x using the quadratic formula or some other way and you get x to be 8 or -9. OH WAIT THERE IS ANOTHER SOLUTION IT IS -9 AND -8. . Anyway yea hoped this helped.
Step-by-step explanation:
The expression x3 – 64 can be written as (x)3 – (4)3. What is the factorization of x3 – 64?
a3 – b3 = (a – b)(a2 + ab + b2)
A. (x – 4)(x2 + 4x + 8)
B. (x – 4)(x2 + 4x + 16)
C. (x – 64)(x2 + 64x + 16)
D. (x – 64)(x2 + 64x + 4,096)
Answer:
B
Step-by-step explanation:
(x - 4) because a = x and b = 4, subsitute into (a - b)
(x2 + 4x + 16) because if a = x and b = 4, you subsitute them into (a2 + ab + b2) to get your answer
A cylinder has a diameter of 7 and height of 10.4 . What is its total surface area to two decimal places
Answer:
305.68
Step-by-step explanation:
π = 3.14(aka pi)
d=diameter
h=height
^=exponent
The formula for doing this types of problem is 2π d/2h + 2π(d/2)^2. So all you do is fill in the diameter and height of the variable.
2π 7/2(10.4) + 2π(7/2)^2=305.68

At Yankee Candle, four large candles and three small candles sell for $34. For
two large candles and one small candle, the cost is $16. Choose a system of
equations to find the cost of large and small candles.
Answer:
the answer is D
Step-by-step explanation:
{4x+3y=34
{2x+y=16
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The system of equations to find the cost of large and small candles are,
4x + 3y = 34
2x + y = 16
Option D is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example: 2x + 4 - 8 is an equation.
We have,
At Yankee Candle, four large candles and three small candles sell for $34. For two large candles and one small candle, the cost is $16.
Large candles = x
Small candles = y
Now,
4x + 3y = 34
2x + y = 16
Thus,
The system of equations to find the cost of large and small candles are,
4x + 3y = 34
2x + y = 16
Option D is the correct answer.

David works in a department store selling clothing. He makes a guaranteed salary of $250 per week, but is paid a commision on top of his base salary equal to 5% of his total sales for the week. How much would David make in a week in which he made $1500 in sales? How much would David make in a week if he made xx dollars in sales?
Answer:
250 + 0.05 (1500)
250 + 75 = $325 david made i a week with 1500 in sales
250 + 0.05(xx) is how much david would make if he sold xx that week
Step-by-step explanation:
i hope this helped :)
A linear function is a function that changes at a constant rate.
David would make $325 if he made $1500 in sales,He would make 250 + 0.05x if he made $x in salesThe given parameters are:
Flat Salary = $250 weeklyCommission= 5%A linear function is represented as:
[tex]C(x) = b + mx[/tex]
Where:
b represents the y-interceptm represents the slopeSo, we have:
[tex]C(x) = 250 + 5\% \times x[/tex]
Express 5% as decimal
[tex]C(x) = 250 + 0.05 \times x[/tex]
[tex]C(x) = 250 + 0.05x[/tex]
On a sale of $1500, the equation becomes
[tex]C(x) = 250 + 0.05 \times 1500[/tex]
[tex]C(x) = 325[/tex]
Hence. David would make $325 if he made $1500 in sales, and he would make 250 + 0.05x if he made $x in sales

Identify the x- and y-intercepts of the equation
4x - y = 8
[tex]\boxed{\boxed{\pink{\sf \leadsto The \ x - intercept \ is \ (2,0) \ \& \ the \ y \ intercept \ is \ (-8,0) }}}[/tex]
Step-by-step explanation:A linear equation is given to us and we are required to find x and y Intercepts to it. So the given linear equation to us is ,
[tex]\bf \implies 4x - y = 8 \\\\\bf\implies \dfrac{1}{8} \bigg( 4x -y\bigg) =\frac{1}{8}\times 8 \\\\\bf\implies \dfrac{4x}{8}-\dfrac{y}{8} = \dfrac{8}{8} \\\\\bf\implies \dfrac{x}{2}-\dfrac{y}{8}=1 \\\\\bf\implies\boxed{\red{\bf \dfrac{x}{2}+\dfrac{y}{-8}=1 }}[/tex]
Hence on comparing to standard form we get
x intercept as (2 , 0 )y intercept as (0,-8) Hence the x - intercept is ( 2 , 0 ) and the y - intercept is ( 0 , -8 ) .Answer:
x = (2,0)
y = (0,-8)
Step-by-step explanation:
Remember than an intercept always has the other number as 0.
Let's put this in standard form of a linear equation, or y = mx + b
4x - y = 8
-y = -4x + 8
y = 4x - 8
"b" is the y intercept. The y intercept is -8, or (0,-8)
Now, to find the x intercept, all we have to do is substitute 0 for y.
0 = 4x -8
8 = 4x
2 = x
The x intercept is 2, or (2,0)

about the origin?
Answer:
The image if the point is (-7, -9)

If The point (x, y) rotated about the origin by angle 90° counterclockwise, then its image is (-y, x)If the point (x, y) rotated about the origin by angle 180° counterclockwise, then its image is (-x, -y)If the point (x, y) rotated about the origin by angle 270° counterclockwise, then its image is (y, -x)∵ The given point is (9, -7)
∴ x = 9 and y = -7
∵ The given point is rotated 270° counterclockwise about the origin
→ By using the third rule above
∴ The image of the point is (y, -x)
→ That mean change the sign of x-coordinate, then switch them
∵ x = 9 and y = -7
∴ The image if the point is (-7, -9)

Answer:
B) 37.5 cm squared!
Step-by-step explanation:
First, we know that a triangular prism has 5 faces, so in order to find the surface area of this prism, we must find the area of each face, and then add them together.
Face 1 (Rectangle): 6.5 * 1.5 = 9.75
Face 2 (Rectangle): 6 * 1.5 = 9
Face 3 (Rectangle): 2.5 * 1.5 = 3.75
Face 4 (Triangle): (6 * 2.5)/2 = 6
Face 5 (Triangle): (6 * 2.5)/2 = 6
Now, we add all the areas of the faces together.
9.75 + 9 + 3.75 + 6 + 6 = 37.5
37.5 is the surface area of the whole triangular prism.

Answer: See explanation
Step-by-step explanation:
PRINCETON:
December - 50
January - 40
Decrease = 50 - 40 = 10
Percentage Decrease = Decrease/Original value × 100
= 10/50 × 100
= 20%
2) WORCESTER:
December - 256
January - 197
Decrease = 256 - 197 = 59
Percentage Decrease = Decrease/Original value × 100
= 59/256 × 100
= 23.05%
3) CHICAGO:
December - 7050
January - 6708
Decrease = 7050 - 6708 = 342
Percentage Decrease = Decrease/Original value × 100
= 342/7050 × 100

The bakers fits 26 rolls on to a pan that measures 1 5/8ft2. How many square feet does the baker use for each roll
Answer: 1/16 ft²
Step-by-step explanation:
The baker put 26 rolls into a pan that has an area of 1⁵/₈ ft².
Each roll is therefore taking up a space of:
= Area/ Number of rolls
Convert the fraction to an improper fraction:
1 ⁵/₈ = 13/8
= 13/8 ÷ 26
= 13/8 * 1/26
= 13/208
= 1/16 ft²
