Answer:
0.75(3/4) part of the roomStep-by-step explanation:
Step one:
given data
we can express the given data mathematically as
John can paint 0.5room in 2/3 hours
let the part of the room he can paint in an hour be x
so
if he takes 2/3 hours to paint 0.5 room
then he will take 1 hour to paint x
cross multiply we have
x= 0.5/2/3
x=0.5*3/2
x= 1.5/2
x=0.75 part of the room
75/100= 15/20=3/4 part
if the solutions of p(x)=0 are -14 and 11, which function could be p?
(A) p(x)=x^2-3x-154
(B) p(x)=x^2-14x+11
(C) p(x)=x^2+14x+11
(D) p(x)=x^2+3x-154
Answer:d
Step-by-step explanation:
The required function is [tex]P(x)=x^2+3x+154[/tex]. So, option D is correct.
Important information:
The solutions of [tex]p(x)=0[/tex] are [tex]-14[/tex] and 11.We need to find the function p(x).
Function:If [tex]x=c[/tex] is a solution of [tex]p(x)=0[/tex], then [tex](x-c)[/tex] is a factor of p(x).
It means [tex](x+14)[/tex] and [tex](x-11)[/tex] are two factor of p(x).
[tex]P(x)=(x+14)(x-11)[/tex]
[tex]P(x)=x^2-11x+14x+154[/tex]
[tex]P(x)=x^2+3x+154[/tex]
Therefore, the correct option is D.

X + 2x + 12y + x Apply the properties of operations by combining like terms to produce an equivalent expression. Prove your answer by showing your work.
Answer:
4(x+3y)
Step-by-step explanation:
Given the expression X + 2x + 12y + x
First thing to do is combine the like terms;
X + 2x + 12y + x
= x+x+2x+12y
Add the like terms(Addition property)
= 4x + 12y
Then factor out the like terms
= 4(x+3y)
Hence the equivalent expression is 4(x+3y)
divide the polynomial 3x^4-6x^2-x/x=
Answer: 3x^3-6x-1
Step-by-step explanation:
Take out an x from everything. Numbers that have powers will just go down a power (ex- 3x^4 would go to 3x^3) and if you have just an x then it turns into one.
The polynomial by the division is equal to [tex]3x^3-6x-1[/tex]
What is a polynomial?They are mathematical expressions involving variables raised with non negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non negative exponentiation of variables involved.
We are given the polynomial
[tex]3x^4-6x^2-x/x[/tex]
We need to divide the polynomial by x.
[tex]3x^4-6x^2-x/x[/tex]
Then we need to factor out x
[tex]x(3x^3-6x- 1)/x[/tex]
The answer is [tex]3x^3-6x-1[/tex]

The perimeter of a kite is 50 mm. The length of one of its sides is 1 mm more than twice the length of another. Find the length of the LONGEST side of the kite. Only write the value of the longest side.
Answer:
The length of the longest side is 13mm
Step-by-step explanation:
Represent the two sides with a and b, where a is the longest
[tex]Perimeter = 50[/tex]
[tex]a=b + 1[/tex]
Required
Determine the length of the longest side
Perimeter of a kite is calculated as thus:
[tex]Perimeter = 2(a + b)[/tex]
Make b the subject in [tex]a=b + 1[/tex]
[tex]b = a -1[/tex]
Substitute a - 1 for b and 50 for Perimeter in [tex]Perimeter = 2(a + b)[/tex]
[tex]50 = 2(a + a - 1)[/tex]
Divide through by 2
[tex]25 = a + a - 1[/tex]
[tex]25 = 2a- 1[/tex]
Add 1 to both sides
[tex]25 + 1 = 2a - 1 +1[/tex]
[tex]25 + 1 = 2a[/tex]
[tex]26 = 2a[/tex]
Solve for a
[tex]a = 26/2[/tex]
[tex]a = 13[/tex]
Hence, the length of the longest side is 13mm

x = (-3±√69)/10
Step-by-step explanation:
Perhaps you want to find the solutions using the quadratic formula.
For the equation ...
ax² +bx +c = 0
The solution is given by the formula ...
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Here, we have a=5, b=3, c=-3, so the values of x are ...
[tex]x=\dfrac{-3\pm\sqrt{3^3-4(5)(-3)}}{2(5)}\\\\\boxed{x=\dfrac{-3\pm\sqrt{69}}{10}}[/tex]
A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t^2+64t+80 gives the height, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?
I already found the maximum height, it's at 144 feet
A. 5
B. 16
C. 2
D. 9
Answer:
5 seccsStep-by-step explanation:
Given the modeled function of the height expressed as;
h(t)=-16t^2+64t+80
The ball hits the ground when h(t) = 0 (when the height is zero)
Substitute into the function and find t;
0 =-16t^2+64t+80
divide through by -16
0 = t²-4t-5
Factorize;
t²-4t-5 = 0
t²-5t+t-5 = 0
t(t-5)+1(t-5) = 0
(t+1)(t-5) = 0
t + 1 = 0 and t-5 = 0
t = -1 and t = 5
Time can't be negative
Hence it will take the ball 5secs before it hits the ground

There are 2.54 centimeters in 1 inch. There are 100 centimeters in 1 meter.
To the nearest inch, how many inches are in 13 meters? Enter the answer in the box.
inches
Answer:
Answer: 512 inches
Step-by-step explanation:
Unit Conversion
We need to recall two basic unit conversions for length:
1 inch = 2.54 cm
1 meter = 100 cm
We are given a length of 13 meters. Converting to centimeters:
13 * 100 = 1300 cm
Now convert to inches dividing by 2.54:

Jessica earns 2,000 per month as a saleswomen. In addition to the salary she earns 80 per product that she sells. If her goal is to earn 10,000 per month, how many products does she need to sell
Answer:
100 products
Step-by-step explanation:
Jessica earns 2,000 per month as a sales woman
In addition to the salary she earns 80 per product that she sells
Her goal is to earn 10,000 per month
Therefore the number of products that will be sold to attain 10,000 can be calculated as follows
= 80×100
= 8,000
= 8,000+2,000= 10,000
Hence she needs to sells 100 products to attain 10,000
