When a number is added to 20 and 5 is subtracted from the number, their product is 150. Find the two possible numbers
Answer:
--15 and --10 respectively
Step-by-step explanation:
Let the first no be a and second no be b
From the interpretation of the question
a + 20 (added) -- 5 (subtracted) = 0
a + 20 -- 5 = 0
a + 15 = 0
a = --15
Product = 150
a×b = 150
(--15) × b = 150
b = --150/15
b = --10

5. Suppose that 25 acres of land is purchased, but because of roads and wetland concerns, 6 2/3 acres can not be developed into lots. How many 5/6 acre lots can the rest of the land be divided into?
22 lots of 5-6 acres each can be created from the remaining area.
What is acres?
The imperial and US customary systems both utilise the acre as a unit of land area. One chain by one furlong (66 by 660 feet) is the traditional definition, which is exactly equal to 10 square chains, 1/640 of a square mile, 4,840 square yards (43,560 square feet), and 4,047 m² (or around 40% of a hectare). An acre may be stated to be exactly 4,046.8564224 square metres based on the international yard and pound agreement of 1959.
Out of 25 acres of land 6 2/3 acres can not be developed into lots.
Therefore land that is left = 25 - 6 2/3 acres
= 25 - 20/3 acres
= 55/3 acres
No.of 5/6 acre lots can the rest of the land be divided into = 55/3 / 5/6 lots
= 22 lots

(c) find x if f(x) = 0
Answer:
A) f(0) = -7
B) f(-3) = 44
C) x = -1, (7/5)
Step-by-step explanation:
2. Let f(x) = 5x² - 2x - 7.
(a) find f(0)
f(x) = 5x² - 2x - 7
f(0) = 5(0)² - 2(0) - 7
f(0) = -7
(b) find f(-3)
f(x) = 5x² - 2x - 7
f(-3) = 5(-3)² - 2(-3) - 7
f(-3) = 5(9) - 2(-3) - 7
f(-3) = 45 + 6 - 7
f(-3) = 45 + 6 - 7
f(-3) = 44
(c) find x if f(x) = 0
f(x) = 5x² - 2x - 7
f(x) = 5x² - 2x - 7 = 0

Point M is the midpoint of AB¯¯¯¯¯. AM=2x+9, and AB=8x−50.
What is the length of AM¯¯¯¯¯¯?
Answer:
43
Step-by-step explanation:
→ Set up an equation
2x + 9 = 0.5 ( 8x - 50 )
→ Simplify
2x + 9 = 4x - 25
→ Minus 4x from both sides
-2x + 9 = -25
→ Minus 9 from both sides
-2x = - 34
→ Divide both sides by -2
x = 17
→ Substitute into AM
2 × 17 + 9 = 34 + 9 = 43
If it laptop computer right now because $1549 and is on sale for $1149 what percentage discount is being given round your answer to the nearest hundredth when necessary
Okay, here we have this:
Considering the following equation:
Sale Price=Original Price*(100%-Percentage discount)
Replacing we obtain:
$1149=$1549*(100%-Percentage discount)
$1149/$1549=(100%-Percentage discount)
0.7417=100%-Percentage discount
Percentage Discount=100%-0.7417
Percentage Discount=1-0.7417
Percentage Discount=0.2583
Percentage Discount=25.83%
Finally we obtain that the discount percentage is 25.83%.

Use a table of trigonometric values to find the angle θ in the right triangle in the following problem. Round to the nearest degree, if necessary.
sin θ = 0.7071 O = 5 H = ?
By applying sine trigonometry, the angle θ in this right angled triangle is approximately equal to 50 degrees.
What is the law of sines?In Trigonometry, the law of sines is also referred to as sine law or sine rule and it can be defined as an equation that relates the side lengths of a triangle to the sines of its angles.
How to apply basic trigonometry?In order to determine the value of H, we would apply basic trigonometry. From the information provided about this right angled triangle, we can logically deduce the following parameters:
sinθ = 0.7071Opposite (Opp) = 5Hypotenuse (Hyp) = H.Therefore, we would use the sine trigonometry to determine the value of H as follows:
Sinθ = Opp/Hyp
0.7071 = 5/H
H = 5/0.7071
H = 7.0711.
Now, we can determine the angle θ in this right angled triangle as follows:
Sinθ = Opp/Hyp
Angle, θ = sin⁻¹(Opp/Hyp)
Angle, θ = sin⁻¹(5/7.0711)
Angle, θ = sin⁻¹(0.7071)
Angle, θ = 44.999 ≈ 50°.
Angle, θ = 50 degrees.

Chris and Beth Micelli made a $235,000 offer for the purchase of a new home, which was accepted. They made a 30% down payment and financed the rest. Using the closing cost table below, find the mortgage total if they include the closing costs in the mortgage amount.
The amount of mortgage will be the remaining amount after they made a downpayment.
Since the downpayment is 30%, the mortgage will be 70% of the purchased amount
So mortage will be :
mortgage = 0.70 x $235,000 = $164,500
From the closing cost table :
There are charges related to the mortgage (Points, Document stamp and Processing fee)
Adding these charges will be :
=2% + 0.30% + 1.10% = 3.4% of the mortgage
So this will give us :
= 0.034 x $164,500 = $5,593
Now to find the total mortgage, add the values in the closing cost table including the mortgage itself.
Total mortgage = 164500 + 5,593 + 252 + 65 + 325 + 212 + 410 + 350 + 450
Answer :

The net force acting on the object is 12.44 N.
In this problem, we are dealing with the magnitude of a vector, where A vector is an object that has both a magnitude and a direction. Geometrically, able to picture a vector as a directed line segment, whose length is the magnitude of the vector, and with an arrow showing the direction. A vector's magnitude is the length of the vector. The magnitude of the vector a is signified as ∥a∥. Since we are provided with magnitudes of the three forces acting on the object which are (-8,5), (0,1), and (4, -7) So we can represent them in terms of vectors which are :
F₁= -8i+5j
F₂= j
F₃ = 4i-7j
The magnitude of a vector is basically to add the individual horizontal and vertical components to get the horizontal and vertical components of the resultant force, then sum up the square of the vertical components and horizontal of the resultant force and take the square root of the result.
F(net) =[tex]\sqrt{}[/tex]( F₁²+ F₂²+ F₃²)

40% of the airplanes were hydroplanes. If 660 were hydroplanes, how many were not hydropons?
40% of the airplanes were hydroplanes.
If 660 were hydroplanes, how many were not hydroplanes?
SOLUTION
If 40% of the airplanes were hydroplanes.
Let x represents the total number of Hydroplanes.
So that 40 % of X = 660
40/ 100 x X = 660
2 / 5 x X = 660
2X / 5 = 660
cross- multiply, we have:
2X = 660 X 5
2 X = 3300
Divide oth sides by 2 , we have :
X = 3300 / 2
X = 1650
Total number of Hydrophones = 1650
Those that are Hydrophones = 660
Those that are not Hydrophones = 1650 - 660
= 990

Remember that to find a distance between two numbers, we have to subtract the least number from the greater one. So, in this case, we have -4 and 5, where 5 is greater than -4.
[tex]5-(-4)=5+4=9[/tex]Therefore, the distance between the numbers is 9.The answer is C.15. The area of a triangle is given by
A = 1/2bh, where b is the base and h is the height of the triangle. In the triangle PQR above, PR=6, PQ=7, QR=12, and PH=3. If PH is perpendicular to QR, what is the area of the triangle PQR?
(A) 12
(B) 18
(C) 36
(D) 42
The answer is (B) 18.
In order to calculate the area of a triangle we must use the equation 1/2·base·height.
In this case, the base of the triangle would be QR, which is 12. The height would be PH, which is 3.
Using the formula above, we can do 1/2·12·3 which equals 18. This is the area of triangle PQR and our final answer.
