Answer:
12 movies
Step-by-step explanation:
If you do not rent any vidoes you will be charged $45 no matter what, so...
Movies + 45 = total charge
each movie is 1.99 and you owe (total charge) $68.88
equation:
1.99x + 45 = 68.88
-45 -45 (subtract 45 from each side to keep equation balanced)
1.99x = 23.88 (now divide both sides by 1.99 to get x alone)
x = 12
you rented 12 movies
Use the distributive property to remove the parentheses.
1. 3(8 + x)
2. 7(v - 2)
3. 3(v - 9)
Answer:
1. 24 + x
2. 7v - 14
3. 3v - 27
Step-by-step explanation:
Distributive property means that you go through something by either multiplying or dividing by whatever may be in the parentheses.
1. For one you would multiply the 3 through. 3 x 8 + 3x which can be simplified into 24 + 3x.
2. For two you would multiply the 7 through. 7v - 7 x 2, which can be simplified into 7v - 14.
3. For three you would multiply the 3 through. 3v - 3 x 9, which can be simplified into 3v - 27

Find a premium on Property worth 20 500000 Rupees at 3% if (1) the property is fully insured (2) the property is insured for 80% of its value
Answer:
1)Premium = 615,000 Rupees
2)Premium = 492,000 Rupees
Step-by-step explanation:
Property worth = 20,500,000 Rupees
Premium rate = 3%
1) the property is fully insured means the property is insured to 100% of its value.
Thus, the insured value = 20,500,000 Rupees
Thus,
the premium = 20,500,000 × 3%
Premium = 615,000 Rupees
2) the property is insured to 80% of its value.
Thus, the insured value = 20,500,000 × 80% Rupees = 16,400,000 Rupees
Thus,
the premium = 16,400,000 × 3%
Premium = 492,000 Rupees
What is the equation of the line
that passes through the point
(-3,-5) and is parallel to the line
2x+3y=15
Answer:
y = (-2/3)*x -7
Step-by-step explanation:
2x+3y=15
3y = -2x + 15
y = (-2/3) *x + 5
slope for parallel line should be -2/3 too
pass (-3 , -5) y = mx + b b = y - mx = (-5) - ((-2/3) * (-3))
b = -5 - 2 = -7
parallel line: y = (-2/3)*x -7

A bucket holds b liters of water. But a jar holds 8 fewer liters than the bucket. How many times can the bucket hold than the jar? Thanks for your help!
Answer:
b / (b - 8)
Step-by-step explanation:
Given that :
Litres of water held by bucket = b
Jar holds 8 litres fewer than bucket; hence, litres held by jar = b - 8
The number of times bucket can hold than jar is :
Litres held by bucket / litres held by jar
b / (b - 8)

write a coordinate proof. Given: Rectangle ABCD has vertices A(0,4), B(6,4), C(6,0), D(0,0). E is the midpoint of line DC. F is the midpoint of line DA. Prove: The area of rectangle DEGF is one fourth the area of rectangle ABCD.
Please help I've been trying for a while
Answer:
The answer is below
Step-by-step explanation:
Distance between two points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)\ on \ the\ coordinate\ plane[/tex]
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The area of rectangle = length * breadth
The area of rectangle ABCD = |AB| * |BC|
[tex]|AB|=\sqrt{(6-0)^2+(4-4)^2}=6\\\\|BC|=\sqrt{(6-6)^2+(0-4)^2} =4[/tex]
The area of rectangle ABCD = |AB| * |BC| = 6 * 4 = 24
E(x, y) is midpoint of line DC. Its coordinate is:
x = (6 + 0) / 2 = 3; y = (0 + 0) / 2 =0
The coordinate of E = (3, 0)
F(a, b) is midpoint of line DA. Its coordinate is:
a = (0 + 0) / 2 = 0; b = (4 + 0) / 2 = 2
The coordinate of E = (0, 2)
The area of rectangle DEGF = |DE| * |DF|
[tex]|DE|=\sqrt{(3-0)^2+(0-0)^2}=3\\\\|DF|=\sqrt{(0-0)^2+(2-0)^2} =2[/tex]
The area of rectangle ABCD = |DE| * |DF| = 3 * 2 = 6
Therefore, area of rectangle DEGF is one fourth the area of rectangle ABCD

i own three dogs 5 cats 7 squirrels 8birds 10 lizards and 4 beetles I told my friends that my ratio of dogs+cats to my other pets is 8:37 but my friend says it is 8:29 Who is correct (if any) and if someone made a mistake what was the mistake
Answer:
The friend is correct
Step-by-step explanation:
The ratio of dogs+cats to the other pets is 29. However the ratio of dogs+cats to the total number of pets is 8:37. Which they didn’t ask for, and ask for the ratio of dogs+cats to other pets.
Answer:
Your friend is correct.
Step-by-step explanation:
You have 3 dogs and 5 cats; that makes [8] pets. Now, add up the rest of your pets (excluding dogs and cats, of course).
7 (squirrels) + 8 (birds) + 10 (lizards) + 4 (beetles) = [29] pets
[8:29]
By the looks of it, the mistake made here was adding up everything when calculating the second part of the ratio, including the dogs and cats (this shouldn't have been done).
Hope this helps, and have a good one.
if triangle fgh m f = m h, gf = x + 40, hf =3x - 20, and gh = 2x + 20. The length of GH is
Answer: it’s 60
Step-by-step explanation:
GH=2x+20=2(20)+20=40+20=60
When two angles are equal in a triangle the opposite sides of them are also equal. The value of the side GH is 60 units.
Given information-In [tex]\Delta FGH [/tex],
[tex]m\angle f=m\angle h[/tex]
The sides of the triangle,
[tex]GF=x+40[/tex]
[tex]HF=3x-20[/tex]
[tex]GH=2x+20[/tex]
Isosceles triangle-An isosceles triangle is a triangle in which two sides and two angle are equal.
When two angles are equal in a triangle the opposite sides of them are also equal. Therefore,
[tex]GF=GH\\ [/tex]
Put the values,
[tex]\begin{aligned}\\ x+40&=2x+20\\ 2x-x&=40-20\\ x&=20\\ \end[/tex]
Thus the value of the GH is,
[tex]GH=2x+20\\ GH=2\times20+20\\ GH=60[/tex]
Thus the value of the side GH is 60 units.

a. Two paths of width 2m each run across the middle of a rectangular
garden of length 60m and breadth 40m. What is the total area
covered by the both paths.
b. The area of a rectangular field is 60000 m². If the ratio of length
and breadth is 3:2, find its perimeter.
Answer:
196 m² ; 1000 m
Step-by-step explanation:
Given that:
Dimension of rectangular garden = 60m by 40m
Width of the 2 paths that run across each other = 2m
Hence,
Area of path 1 = (length * width) = (60 * 2) = 120m²
Area of path 2 = (breath * width) = (40 * 2) = 80m²
Area of Point where both paths cross each other (2 * 2) = 4m²
Total area covered by both path = (120m² + 80m² - 4m²) = 196m²
B.)
Area of rectangular field = 60000m²
Ratio of length and breadth = 3 : 2
Length * breadth = 60000
x ; breadth = (2/3)x
x * (2/3)x = 60000
2/3 x² = 60000
x² = 60000 ÷ 2/3
x² = 40,000
x = sqrt(40000)
x = 200
(3/2) * 200 = 300
Length = 300
Hence,
Perimeter = 2(length + breadth)
Perimeter = 2(300 + 200)
Perimeter = 2(500)
Perimeter = 1000m
