Answer:
x = 10/3 or x = -16/3
Step-by-step explanation:
3x+3 = 13
3x =10
x = 10/3
3x+3 = -13
3x = -16
x = -16/3

You drop a ball from a height of 1.5 meters. Each curved path has 74% of the height of the previous path. a. Write a rule for the sequence using centimeters. The initial height is given by the term n = 1. b. What height will the ball be at the top of the sixth path?
A. A(n) = 150 • (0.74)^n–1 ; 33.29 cm
B. A(n) = 1.5 • (0.74)^n–1 ; 0.33 cm
C. A(n) = 150 • (74)^n–1 ; 332,850,993,600 cm
D. A(n) = 0.74 • (1.5)^n–1 ; 5.62 cm
Answer:
A. A(n) = 150 • (0.74)^n–1 ; 33.29 cm
Step-by-step explanation:
This is a geometric sequence.
a%5B1%5D=1.5m=150cm, r=0.74
The formula is
a%5Bn%5D=a%5B1%5Dr%5E%28n-1%29
Just substitute a1 = 150cm and r = 0.74
a%5Bn%5D=150%280.74%29%5E%28n-1%29
That's the rule.
For the second part, substitute n = 6

He also spent 1/8
of his pocket money on a scarf at the match.
(a) What fraction of his pocket money has Harry spent?
(b) What fraction of his pocket money does Harry have left?
The fraction of money spent is 5 / 8 x.
The fraction of money left is 3 / 8 x.
How to find the fraction of money he spent?This week Harry spent 1/2 of his pocket money on a ticket for a football match. Therefore,
let
x = amount of money he has
Therefore,
amount spent on football match = 1 /2 x
He also spent 1/8 of his pocket money on a scarf at the match.
Therefore,
amount spent on scarf = 1 / 8 x
Fraction of money spent = 1 / 2 x + 1 / 8 x = 4 + 1 / 8 = 5 / 8 x
Fraction of money left = x - 5/8 x = 8x - 5x/8 = 3 / 8 x

Find the equation of the lines perpendicular and parallel to 2x-3y=8 line through the point (-2,-4)
Answer:
y= -1.5x-7 is the equation of the perpendicular line
Here's why:
when we convert 2x-3y=8 to standard form, we get y= 2/3x-8/3. This means the perpendicular line will have a slope of the negative reciprocal of the original one, so the perpendicular slope is -1.5. When we substitute the points (-2,-4) into the equation y=-1.5x+b, we get a b value of -7. So the perpendicular line equation is y= -1.5x-7. You can't the parallel line equation with the points (-2,-4) as it is part of the line 2x-3y=8.
Four students took an exam. The fraction of the total possible points that each received is given. Which student had the highest score? A. Monica, 22/55
B. Lily, 17/20
C. Nikki, 4/5
D. Sydney, 3/4
Answer:
B
Step-by-step explanation:
The easiest way to find the answer is to convert all of the fractions to have the same denominator,...
A = (22/55 / 11 = 2/5 and 2/5 * 20) = 40/100
B = (17/20 * 5) = 85/100
C = (4/5 * 20) = 80/100
D = (3/4 * 25) = 75/100
B (Lily) is the highest followed by C (Nikki), D (Sydney), and A (Monica)

A square pool has an area of 169ft^2 . What is the side length of the pool?
Area of a square is side ^2
To find the length of the side using area find the square root of the area.
Side length = sqrt(169)
Side length = 13 feet
Answer:
13 ft
Step-by-step explanation:
The area of a pool is length × width (l × w) , but the length and width are the same so I'll use [tex]b[/tex] representing both length and width:
A = l × w
A = [tex]b^{2}[/tex]
Area of the pool is 169
169 = [tex]b^{2}[/tex]
[tex]b[/tex] = [tex]\sqrt{169}[/tex]
[tex]b[/tex] = 13

In this situation, As we rise to higher attires, the temperature lowers therefore, only Option B [42. 1º. 40.5º. 39. 70. 34.49. 30.00] follows that requirement.
Now show why there are other possibilities wrong
Option A increases with the altitude, which violets the particular condition.Option C again increases at this temperature as the altitude increases and abruptly falls to 20, which is not our condition.option D up to 51.8 sounds excellent, however, this is achievable as is our given situation but the temperature goes to 59.3, therefore, this option is also refused.Learn more:

Which planets would you MOST LIKELY be able to see in the night sky without a telescope?
A)
Venus and Saturn
B)

D)
Mercury and Neptune
Answer:
There are 5 planets visible without a telescope, Mercury, Venus, Mars, Jupiter, and Saturn (6 if you include Uranus for those with sharp eyes!). All of them plus Neptune move within 7 degrees of the ecliptic.
Venus. After the Moon, Venus is the brightest natural object in the night sky. It is both the Earth's closest neighbor in our Solar System and the planet most similar to Earth in size, gravity, and composition. We can't see the surface of Venus from Earth, because it is covered with thick clouds.

please mark me brainliest pleasethe floor of a room is 12 m long and 6 m wide the floor of this room is to be fitted with tiles of dimension 10 cm x 2 cm what will the total expense in Rupees if the cost of tiling is 5 atile
Step-by-step explanation:
the price is 5 per tile ?
the area of the rectangular room is
12×6 = 72 m²
each m² has 100×100 = 10000 cm²
so, we have for the total area in cm²
72 × 10000 = 720000 cm²
one tile has 10×2 = 20 cm²
so, how many tiles will we need ?
720000 / 20 = 72000 / 2 = 36000 tiles.
so, if truly 1 tile costs 5 Rupees, then we have
36000 × 5 = 180000 Rupees as total costs.
Step-by-step explanation:
1 m = 100 cm
12 m = 1200 cm
6 m = 600 cm
Area of room = l × w
Area = 1200 × 600
Area = 720000 cm²
Area of tile = l × w
Area = 10 × 2
Area = 20 cm²
Total tile = 720000/20 = 72000/2 = 36000
Cost = 36,000 × 5
Cost = $ 180000

Angle PRS is 98 degree. It is made of two smaller angles. One smaller angle is 3x-8 and the other one is 2x+6. What is the measure of the smaller angle?
Answer:
46
Step-by-step explanation:
The sum of the two smaller angle measures is 98.
(2x + 6) + (3x - 8) = 98
Combine like terms.
5x - 2 = 98
5x = 100
x = 20
Plug this into the expressions for the two smaller angle measures.
2x + 6 = 2(20) + 6 = 46
3x - 8 = 3(20) - 8 = 52
The smaller of the two angles measures 46.
