Final answer:
After calculating the cost for 6 hours of bicycle rental on Saturday, we subtracted that from the total cost to determine the cost for Sunday. By dividing this amount by the hourly rate, we concluded that Mr. Scott rented the bicycle for an additional 6 hours on Sunday.
Explanation:
The question asks how many hours Mr. Scott rented a bicycle on Sunday. To solve this, we need to calculate the total rental hours using the cost information provided. We know that Mr. Scott rented the bicycle for 6 hours on Saturday, and the rental cost is $4 per hour. He paid a total of $48 for the entire rental period over the two days.
First, let's calculate the cost for Saturday's rental: 6 hours × $4 per hour = $24. Now we know that Mr. Scott spent $24 on Saturday, so the remaining $24 ($48 total - $24 for Saturday) must have been spent on Sunday's rental. Dividing the remaining cost by the hourly rate gives us the number of hours rented on Sunday: $24 ÷ $4 per hour = 6 hours. Therefore, Mr. Scott rented the bicycle for 6 hours on Sunday as well.

A circle whose area is 4 has a radius of x find the area of a circle whose radius is 3x
Answer:
Area = 36 units.
Step-by-step explanation:
Given : A circle whose area is 4 has a radius of x .
To find : find the area of a circle whose radius is 3x.
Solution: We have given
Area of circle = 4 units.
Radius = x .
Formula of area = pi (radius)².
Plug the values
pi (x)² = 4 -------(A)
If the radius = 3x .
Then 4
Area = pi (3x)².
Area = pi (9)(x)².
Area = 9 pi (x)²-----(B) .
We can see from equation ( A) 4 = pi (x)²
Area = 9 * 4.
Area = 36 units.
Therefore, Area = 36 units.

Chris is in training for a bicycle race. He needs to ride 50 kilometers a week as a part of his training. He rode 18.23 kilometers on Monday and 13.94 kilometers on Tuesday.
How much more does Chris need to ride to complete his training for the week ?
A. 4.29 km
B. 17.83 km
C.31.77 km
D. 36.06 km
add how many he rode already:
18.23 + 13.94 = 32.17
now subtract that from 50:
50 - 32.17 = 17.83
answer is B. 17.83 km
Lexi had planted seeds in 3/5 of the garden. She used 1/2 pound of seeds. How many pounds will she use for the entire garden?
Answer:
Lexi will use [tex]\frac{5}{6}[/tex] pounds of seeds.
Step-by-step explanation:
Lexi has planted seeds in [tex]\frac{3}{5}[/tex] of the garden. We know that to plant that part she used [tex]\frac{1}{2}[/tex] pound of seeds.
The entire garden is [tex]\frac{5}{5}=1[/tex].
Then if you multiply [tex]\frac{1}{2}[/tex] in [tex]\frac{5}{5}=1[/tex] and then divide the result in [tex]\frac{3}{5}[/tex] you will obtain how many pounds will she use for the entire garden. (It's a rule of three)
[tex](1).\frac{1}{2} :\frac{3}{5}=\frac{1}{2} :\frac{3}{5}=\frac{5}{2.3}=\frac{5}{6}[/tex]
Lexi will use [tex]\frac{5}{6}[/tex] pounds of seeds.
Let y be inversely proportional to x. if x doubles, what happens to y?
Final answer:
If x doubles and y is inversely proportional to x, then y will become half of its original value, as per the inverse proportionality relation y = k/x.
Explanation:
When variables y and x are inversely proportional, this means that as one value increases, the other value decreases. The relationship between y and x in this case is represented by the equation y = k/x, where k is the proportionality constant. If the value of x doubles, looking at the relationship expressed by the inverse proportionality equation, the value of y will decrease by half.
So, if x becomes 2x, then y becomes k/(2x), which is half the value of the original y if we assume that k is constant. This is reflective of the more-less relationship inherent to inverse proportionality, where increased values of one variable lead to decreased values of the other.

A paper hat is folded into the shape of a kite, as shown. What total length of ribbon is needed to line the two long sides of the hat? 10 in. 11 in. 20 in. 22 in.
Answer:
Step-by-step explanation:
your answer is d
A kite is a quadrilateral with four sides that may be divided into two adjacent pairs of equal-length sides. The total length of ribbon that is needed to line the two long sides of the hat is 22 inches.
What is a kite?A kite is a quadrilateral with four sides that may be divided into two adjacent pairs of equal-length sides. A parallelogram, on the other hand, has two sets of equal-length sides that are opposite each other rather than adjacent.
Since the two adjacent small and two adjacent long sides of a kite are always equal. Therefore, the length of the smaller sides can be written as,
(2x + 1) inches = 5 inches
2x + 1 = 5
2x = 4
x = 2
Now, the length of the longer side of the kite can be written as,
(3x + 5) inches
= 3(2) + 5
= 11 inches
As both the long sides are needed to be covered with the ribbon, therefore, the length of the ribbon needed is,
Ribbon needed = 11 inches × 2
= 22 inches
Hence, the total length of ribbon that is needed to line the two long sides of the hat is 22 inches.

As per an axiom in Euclidean geometry, if__ points lie in a plane, the___containing those points also lies in the same plane.
1. two or three
2. plane or line
Answer:
1. Two
2. Line
Step-by-step explanation:
Two out of the five axioms of the Euclidean Geometry are:
1. A straight line can be drawn between any two points.
2. Any straight line can be extended infinitely.
So, from the above axioms, we get that 'If two points lie in a plane, a straight line can be drawn between those points and that line can be extended indefinitely in that plane'.
Hence, 'If TWO points lie in a plane, the LINE containing those points also lie in the same plane'.

Answer: [tex]-2\dfrac{1}{10}[/tex]
Step-by-step explanation:
The given expression to simplify : [tex]5\dfrac{1}{4}\div-2\dfrac{1}{2}[/tex] (i)
First we convert mixed fraction into improper fraction as :
[tex]5\dfrac{1}{4}=\dfrac{5\times4+1}{4}=\dfrac{20+1}{4}=\dfrac{21}{4}[/tex]
[tex]-2\dfrac{1}{2}=-\dfrac{2\times2+1}{2}=-\dfrac{4+1}{2}=\dfrac{-5}{2}[/tex]

ALGEBRA 2- Which property of addition is shown below?
If x = 1 + 2i and y = –1 – 2i, then x + y = 0.
A. commutative property
B identity property
C associative property
D inverse property
Answer:
D inverse property
Step-by-step explanation:
x=1+2i
y=-1-2i
Both x and y are complex numbers with both real and imaginary parts.
x+y = (1+2i) + (-1-2i)
= 1 + 2i - 1 - 2i
= (1 - 1) + (2i-2i)
= 0 + 0 = 0
Since the two given complex numbers add up to 0, this means that each number is the additive inverse of the other.
So x is the inverse of y and y is the inverse of x.
Among the given options, option D , namely, inverse property is the correct one.

PLEASE HELP!!! Write the equation that describes the simple harmonic motion of a particle moving uniformly around a circle of radius 8 units, with angular speed 5 radians per second
The equation that describes the simple harmonic motion of a particle moving uniformly around a circle is x(t) = Acos(wt + φ). In this case, the equation is x(t) = 8cos(5t + φ).
The equation that describes the simple harmonic motion of a particle moving uniformly around a circle can be derived using the concept of circular motion and trigonometry.
The equation for the position of the particle is given by x(t) = Acos(wt + φ), where A is the radius of the circle, w is the angular speed, t is the time, and φ is the phase shift.
In this case, the radius of the circle is 8 units and the angular speed is 5 radians per second. Therefore, the equation for the simple harmonic motion of the particle is x(t) = 8cos(5t + φ).

Tamara earns her living as a salary plus commission employee. Her annual salary is $48,000, and she earns 4% commission on all sales she makes. If Tamara wants to make a total of $6,000 this month, how much in sales does she need to have?
Answer:
$5,000 in sales
Step-by-step explanation:
dividing the annual salary by 12 to find how much she makes in a month:
48,000/12 = $4,000
If she wants to make $6,000 this month, she needs
6,000 - 4,000 = $2,000 in comissions
$2,000 is the 4% of how much she made in sales.
denoting the total of sales by x:
4%x = 2,000
---> 0.04x = 2,000
this makes x = 2,000/0.04
--> x = $50,000
So to get a moth salary of $6,000 she needs to have $5,000 in sales
