The diagram gives information about two paintings, P and Q.
Each painting is in the shape of a rectangle.
Painting P has an area 1400 cm more than the area of painting Q.
Work out the area of painting P.
Answer: 2600 cm^2
Step-by-step explanation:
FORMULA
Painting P area = Painting Q area + 1400
so...
40(3x-10) = 30(x+15) + 1400
EXPAND EXPAND
120x - 400 = 30x + 450 + 1400
SIMPLIFY
120x-400 = 30x + 1850
+400 +400
120x = 30x + 2250
- 30x - 30x
90x = 2250
DIVIDE BY 90 DIVIDE BY 90
x = 25
SO... Now we have to find the AREA of PAINTING P
LENGTH: (3x - 10)= 3(25) - 10 = 65cm
HEIGHT: 40cm
AREA OF PAINTING P = 65cm X 40cm = 2600cm^2
By solving a system of equations, we will see that the area of painting P is 2,600 cm^2
How to get the area of painting P?Remember that the area of a rectangle of length L and width W is:
A = L*W
Then the area of painting P is:
A = 40cm*(3x - 10)cm
The area of paint Q is:
A' = (30 cm)*(x + 15)cm
And que know that:
A = A' + 1400cm^2
Then we havea system of equations:
A = A' + 1400cm^2
A = 40cm*(3x - 10)cm
A' = (30 cm)*(x + 15)cm
First, we can replace the third equation into the first one to get:
A = (30 cm)*(x + 15)cm + 1400cm^2
And that must be equal to:
A = 40cm*(3x - 10)cm
So now we can solve:
40cm*(3x - 10)cm = (30 cm)*(x + 15)cm + 1400cm^2
for x.
It gives:
120cm*x - 400cm^2 = 30cm*x + 1850 cm^2
120cm*x - 30cm*x = 1850cm^2 + 400cm2
x = (2250cm^2)/(90cm) = 25cm
Now that we know x, we can get the area of painting P.
A = 40cm*(3*25cm - 10cm) = 2,600cm^2

Answer:
1) If we have a point (x, y), the angle between the x-axis and a ray that goes from the origin to the point is defined by:
cos(θ) = x/(√(x^2 + y^2))
sin(θ) = y/(√(x^2 + y^2))
Then for the point:
(√(7)/4 , 3/4)
x = √(7)/4
y = 3/4
√(x^2 + y^2) = √((√(7)/4)^2 + ( 3/4)^2) = (1/4)*√(7 + 9) = 1
Then replacing these values in the above equations for the cosine and sine functions, we get:
cos(θ) = x/(√(x^2 + y^2)) = (√(7)/4)/1 = √(7)/4
sin(θ) = y/(√(x^2 + y^2)) = (3/4)/1 = 3/4
2) To find the period, we just need to find the distance between two peaks, or two x-intersects (such that the slope is the same).
Let's look at the graph.
We can see that at x = 0, the graph intersects the x-axis and increases
The next point where this happens is at x = π/3
Then the period of this function is:
P = π/3 - 0 = π/3
The period is π/3

The height of the triangle is 15 centimeters.
Given the following data:

Find the values of x and y. Write your answers in simplest form.
Answer:
To find X you'll need this formula Tan 30, and this one to find y cos 30.
Step-by-step explanation:
tan 30 = 9 / x.
tan 30*x = 9
x = 9 / tan 30
x = 15.58
To find y, the value of X will be needed, which is 15.5 that we just found.
Cos= A/H
Cos 30 = 15.58/ y
Cos 30 * y = 15.58
y = 15.58/ cos 20
y = 17.99

How many moles of oxygen atoms are in 2.000 x 10^15 molecules of sulfur dioxide (SO2)?
Answer:
6.64*10^(-9) moles of oxygen.
Step-by-step explanation:
If we have N molecules, the number of moles is given by:
n = N/Nₐ
where Nₐ is the Avogadro's number:
Nₐ = 6.02214076*10^23
In 2.000*10^15 molecules of sulfur dioxide, we have:
n = (2.000*10^15)/(6.02214076*10^23) = 3.32*10^(-9) moles of sulfur dioxide.
Now, sulfur dioxide has two oxygens and a single sulfur.
Then a mole of sulfur dioxide has two moles of oxygen and a single mol of sulfur.
Then in 3.32*10^(-9) moles of sulfur dioxide, we have twice that amount moles of oxygen, or:
2*3.32*10^(-9) = 6.64*10^(-9) moles of oxygen.

O4
O 20
O 100
O 200
Answer:
20
Step-by-step explanation:
2 x 10 = 20
divided by 4 = 5
The larger pool will hold is 100 times more gallons than the smaller pool
What is capacity and measurement?From the question, we are to determine how many times more gallons the larger pool holds than the smaller pool
From the given information,
Capacity of the larger pool = 2 × 10¹⁰ gallons
Capacity of the smaller pool = 2 × 10⁸ gallons
To determine how many times more gallons the larger pool holds more than the smaller pool, we will simply divide the capacity of the larger pool by the capacity of the smaller pool
That is,
[tex]\frac{2 \times 10^{10} }{2 \times 10^{8}}[/tex]
= 10²
= 100
Hence, the larger pool will hold is 100 times more gallons than the smaller pool.

A rectangular tabletop has an area of.......
[tex]t^2+2t-99[/tex]
What are the possible dimensions of the tabletop? Use factoring.
The order doesn't matter, so you could say "t+11 and t-9" to mean the same thing.
=======================================================
Explanation:
Think of two numbers that multiply to -99, but also add to 2. In other words, find two factors of -99 which add to 2. We'll use trial and error.
Here are all the ways to multiply to -99 using integers only:
1 and -993 and -339 and -1111 and -933 and -399 and -1Add up each factor pair to see which sum is equal to 2.
1 + (-99) = -983 + (-33) = -309 + (-11) = -211 + (-9) = 2 is what we want33 + (-3) = 3099 + (-1) = 98We can see that 11 and -9 are the two numbers we're after, so therefore, t^2+2t-99 factors to (t-9)(t+11). The order doesn't matter with the factor multiplication.
As a more efficient alternative method, you can use the quadratic formula to solve t^2+2t-99 = 0 to end up with t = 9 and t = -11. That would lead to the two equations t-9 = 0 and t+11 = 0. Applying the zero product property then gets us (t-9)(t+11) = 0.
To help show that (t-9)(t+11) becomes t^2+2t-99, you can use the FOIL rule to expand that factorization out. This is one way to verify the answer.

Uhh I’m doing math work and I need help! I’m doing Solve the system of linear equations using substitution. And I have this problem and I keep getting -6 for y but the right answer for y is positive 6; can someone tell me what I’m doing wrong?!?
Answer:
x=0 and y=6
Step-by-step explanation:
First, you would solve x=y-6 for x.
x=y-6 so you substitute the x in -6x-2y=-12 with (y-6)
-6x-2y=-12 → -6(y-6)-2y=-12
Simplify both sides of the equation = -8y+36=-12
Add -36 to both sides to remove it = -8y+36+-36=-12+-36
-8y+36+-36=-12+-36 → -8y=-48
Divide both sides by -8 to remove it. [tex]\frac{-8y}{-8} =\frac{-48}{-8}[/tex] → y=6
I believe where you went wrong was with where you substituted y-6.
y-6 is the substitute for x so in parenthesis you would put (y-6) where x is in -6x-2y=-12 making the new equation -6(y-6)-2y=-12.

Strictly increasing functions:
Let a function f(a) for x = a, then,
f(a + h), for x = a + h,
If f(a + h) > f(a), we say this a strictly increasing function, as with increase in x, f(x) also increases.
In the given graph, there are straight lines so you can say increasing interval would have +ve slope.
For x = -4 to 0, it increases = [-4, 0]
For x = 2 to 5, it increases = [2, 5]
Answer: [-4, 0], [2, 5]

Women 76 424 500
Men 169 331 500
Total {occupation wise} 245 755 1000 [Grand Total]
1) Probability (any person in S & E) = Total people in S & E / Total people = 245 / 1000 = 0.245
2) Prob (woman & works in S & E) , ie P (W ⋂ S) = Total women in S & E / Total people = 76 / 100 = 0.76
3) Prob (woman or works in S & E), ie P (W U S) = P( Women) + P (S & E) - Prob (Women & SE), ie P (W) + P (S &E) - P (W ⋂ S) = ( 500 + 245 - 76 ) / 1000 = 669 / 1000 = 0.669
The probability that a randomly selected person works in an S&E occupation is 0.245.
The probability that a randomly selected person is a woman and works in an S&E occupation is 0.12.
The probability that a randomly selected person is a woman or works in an S&E occupation is 0.745
What are the probabilities?
Probability determines the odds that an event would happen.
The probability that a randomly selected person works in an S&E occupation = total number of people that work in SE / total number of people= 245 / 1000 = 0.245.
The probability that a randomly selected person is a woman and works in an S&E occupation = (number of women / total number of people surveyed) x (number of people that work in SE / total number of people surveyed)
500 / 1000 x (245 / 1000) = 0.12
The probability that a randomly selected person is a woman or works in an S&E occupation = (number of women / total number of people surveyed) + (number of people that work in SE / total number of people surveyed)
= 500 / 1000 + (245 / 1000) = 0.745
