Answer:
[tex]\huge \boxed{x < 3}[/tex]
Step-by-step explanation:
4x - 1 < 11
Add 1 on both sides.
4x - 1 + 1 < 11 + 1
4x < 12
Divide both sides by 4.
(4x)/4 < 12/4
x < 3
Simplify 3 x times the fraction 1 over x to the power of negative 4 times x to the power of negative 3.
Answer:
3x^2
Step-by-step explanation:
Given:
(3x) * {(1/x)^-4 }* (x^-3)
=(3x) * {1 ÷ (1/x)^4} * {1/x^3}
=(3x) * {1(x/1)^4} * (1/x^3)
=(3x) * (x^4) * (1/x^3)
=(3x) (x^4) (1) / x^3
Multiply the denominators
=3x^5 / x^3
Can also be written as
=3*x*x*x*x*x / x*x*x
Divide the x
= 3*x*x / 1
=3x^2

Vince went on a 333 day hiking trip. Each day, he walked 3\4 the distance that he walked the day before. He walked 83.2583, point, 25 kilometers total in the trip.
Answer:
x= 36 km
Step-by-step explanation:
Vince went on a 3 day hiking trip. Each day, he walked 3/4 the distance that he walked the day before. He walked 83.25 kilometers total in the trip. How far did Vince walk on the 1st day of the trip?
Assume vince walked x km on the first day .
The following equation can be formed
x + 3/4 x + (3/4)^2 x = 83.25
x + 0.75x + 0.5625x = 83.25
Add the like terms
2.3125x = 83.25
Divide both sides by 2.3125
x = 36 km.

ABCD RECTANGLE α + β = ?
Answer:
Step-by-step explanation:
I'm going to walk through this analytically, so I will have to assign some variables to angles that are not marked. Pay close attention so you can follow the logic.
The angle at the top left next to and to the left of 40 will be "x", and the one to the right of 40 will be "y". Because that angle is a right angle, then we know that
x + y + 40 = 90 and
x + y = 50.
We also know that, by the Triangle Angle-Sum Theorem, the 2 triangles that contain alpha and beta will add up to equal 360, 180 apiece. So now we have:
x + 90 + α + y + 90 + β = 360.
Let's regroup a bit:
x + y + α + β + 90 + 90 = 360 and
(x + y) + α + β + 180 = 360.
But we know from above that x + y = 50, so
50 + α + β + 180 = 360 and
230 + α + β = 360 and
α + β = 130. There you go!
Answer:
α + β = 130
Step-by-step explanation:
∠ A = ∠ C = 90°
The sum of the 3 angles in a triangle = 180°
vertex angle at D inside the Δ = 180 - (90 + α ) ← Δ on left
vertex angle at D inside the Δ = 180 - (90 + β ) ← Δ on right
∠ ADC = 90° thus
180 - (90 + α) + 180 - (90 + β) + 40 = 90
180 - 90 - α + 180 - 90 - β + 40 = 90, that is
220 - α - β = 90 (add α and β to both sides )
220 = 90 + α + β (subtract 90 from both sides )
130 = α + β

7. Verify the following: i) (ab + bc) (ab – bc) + (bc + ca) (bc – ca) + (ca + ab) (ca – ab) = 0 ii) (a + b + c) (a² + b² + c² – ab – bc – ca) = a³ + b³+ c³ – 3abc iii) (p – q) (p² + pq + q²) = p³ – q³. EXPLAIN
1. (ab + bc) (ab – bc) + (bc + ca) (bc – ca) + (ca + ab) (ca – ab) = 0
We know that (a+b)(a-b) = a²-b²
(ab + bc)(ab -bc) can be written as a²b² - b²c²
(bc + ca)(bc -ca) can be written as b²c² - c²a²
(ca + ab)(ca - ab) can be written as c²a² - a²b²
→ a²b² - b²c² + b²c² - c²a² + c²a² - a²b²
→ a²b² - a²b² - b²c² + b²c² - c²a² + c²a²
→ 0
2. (a + b + c) (a² + b² + c² – ab – bc – ca) = a³ + b³+ c³ – 3abc
→ a³ + ab² + ac² -a²b - abc -ca² + a²b + b³ + bc² - ab² - b²c - abc + a²c + b²c + c³ - abc - bc² - c²a
→ a³ + b³+ c³ + (- abc - abc - abc) + (ab² - ab² )+ (ac² - ca² ) -(a²b + a²b )+ (bc² - bc² )+ (a²c - c²a) + (b²c - b²c)
→ a³+b³+c³ - 3 abc .
3. (p – q) (p² + pq + q²) = p³ – q³.
→ p³ + p²q + pq² - p²q - pq² - q³
→ p³ - q³ +(p²q - p²q) + (pq² - pq²)
→ p³ - q³
A business tenant has a percentage lease stating rent payment is greater of 2% of the business's total gross sales volume or a minimum base rental of $1,000.00 per month. In the past year, sales totaled $435,000. How much rent did the business pay?
Answer:
The answer is $12,000. 12 months × $1,000 per month = $12,000 minimum annual base rent; $435,000 gross sales × 2% = $8,700. The tenant paid $12,000 because the minimum base rent was more than the percentage of gross sales.

Kia was 200 m north of the Liebrary when he remembered he had to return some books to the library it took him to 200 seconds to do the round-trip which best describes cost round-trip
Answer:
His speed is 2 m/s
His velocity is 0 m/s
Step-by-step explanation:
I'll assume the question is
Kia was 200 m north of the Library when he remembered he had to return some books to the library it took him to 200 seconds to do the round-trip which best describes hist round-trip.
Kia's distance from the Library is 200 m
the round-trip took him 200 s
The total distance for the round trip = 200 x 2 = 400 m
His displacement for the round trip = 0 m (since he returns to his original position)
His speed = distance/time = 400/200 = 2 m/s
His velocity = displacement/time = 0/200 = 0 m/s
Observe the figure drawn, in which a square of side 15cm is removed from one corner of the given rectangle. Find the perimeter of the shaded region. Pls answer, no other irrelevant answer. Pls solve this. I will follow you if you do it. It's urgent!!!
Step-by-step explanation:
Let's start by finding the area of figure 1
The square:
15cm×15cm=225cm²
Then we're going to find the area of figure 2
it's a rectangle (A=L×W)
L=60cm-15cm(because those cm have been cut off)=45cm
W=40cm
Area=45cm×40cm
=1800cm²
Then we add up the sum
Area of 1+Area of 2
=225cm²+1800cm²
=2025cm²
Answer:
140 cm is the perimeter of the unshaded shape.
Step-by-step explanation:
Perimeter of the rectangle in whole = 2l + 2w
Where length is 60 cm and width is 40 cm.
P = 2 × 60 + 2 × 40
= 120 + 80
= 200 cm
To find the perimeter of the unshaded square = 4l
Where the length is 15 cm.
P = 4× 15
= 60 cm
To find the perimeter of the shaded shape = Perimeter of rectangle - Perimeter of unshaded square.
P = 200 - 60
= 140 cm
140 cm is the perimeter of the unshaded shape.

Euclid's division lemma : Let a and b are two positive integers. There exist unique integers q and r such that
a = bq + r, 0 [tex]\leqslant[/tex] r < b
Or We can write it as,
Dividend = Divisor × Quotient + Remainder
Work out:
Given integers are 240 and 228. Clearly 240 > 228. Applying Euclid's division lemma to 240 and 228,
⇛ 240 = 228 × 1 + 12
Since, the remainder 12 ≠ 0. So, we apply the division dilemma to the division 228 and remainder 12,
⇛ 228 = 12 × 19 + 0
The remainder at this stage is 0. So, the divider at this stage or the remainder at the previous age i.e 12

Answer:
Weight of wastage=179.775kg
weight of rice cultivated= 585.225 kg
percentage of rice cultivated=76.5%
Step-by-step explanation:
Area of land=100 square meters
Cultivated rice=765kg
Wastage=23.5%
1) Weight of the wastage=23.5% of 765kg
=23.5/100 × 765
=17977.5 / 100
=179.775 kg
2) Weight and percentage of rice cultivated.
weight of rice cultivated = 765 kg - 179. 775 kg
= 585.225 kg
percentage of rice cultivated = 100 - 23.5
= 76.5%
3) if area is increased 40 times in size
New area=1000 square meters × 40
=40,000 square meters
Cultivated rice= 765kg × 40
=30,600 kg
Cultivated rice excluding wastage=585.225 kg × 40
=23,409 kg

A rectangle has an area of 21x+81. If the width is 3 units, what is the length of the rectangle
Answer:
(7x + 27) units
Step-by-step explanation:
A rectangle is a quadrilateral (has four sides) in which opposite sides are equal and parallel, also all the angles are equal. The area of a rectangle is given as:
Area = Length × Width
Given that the area of the rectangle is 21x + 81 and the width is 3 unit, to find the length of the rectangle, we have to use the formula of the area and then get the length. Therefore:
Area = Length × Width
21x + 81 = Length × 3
Length = (21x + 81) /3
Length = 7x + 27
The length of the rectangle is 7x + 27 units
