How large of a circle would it
take to fit 10,000 toy cars
inside?
The largeness of the circle is an illustration of proportions
Using the assumed parameters, the circle must be 200 times larger than a normal circle
How to determine the size of the circle?The question is incomplete; so I will make use of assumed values
Assume that a normal circle of radius r can take up to 50 toy cars.
When the normal circle is replaced by a larger circle of radius R to take up to 10000 toy cars, the size of the circle must be:
Size = 10000/50
Divide
Size = 200
This means that the circle must be 200 times larger than a normal circle

The length of a rectangle is eight more than twice its width. The perimeter is 96 feet. Find the dimensions of the rectangle
Variable=
Equation=
Step-by-step explanation:
Length = L
Width = W
L=8 more than 2W
L = 8 * 2W
L = 16W
Perimeter = 96
perimeter is the lengths of all sides added together
so
2L + 2W = 96
we have
L = 16W
2L + 2W = 96
let's do substitution
put what L = into 2L + 2W = 96
so
2(16W) + 2W = 96
can you rearrange that to get w

If ΔRST congruent to ΔNPQ, which of the following is true? A. ∠R congruent to ∠P B. ∠R congruent to ∠Q C. ∠T congruent to ∠P D. ∠T congruent to ∠Q
Answer:
Step-by-step explanation:
The order of the expression for congruent shapes indicate the
corresponding vertices between the two shapes that are congruent.
The option which is true is D. T = Q.
Reasons:
The given statement is; ΔRST ≅ ΔNPQ
By Corresponding Parts of Congruent Triangle are Congruent, CPCTC, we
have; The sides on ΔRST are congruent to the corresponding sides of ΔNPQ
Therefore;
RS ≅ NP
RT ≅ NQ
ST ≅ PQ
By CPCTC, we have that the angles on ΔRST are congruent to the corresponding angles of ΔNPQ
Therefore;
∠R ≅ ∠N
∠S ≅ ∠P
∠T ≅ ∠Q
Which gives, by definition of congruency;
∠R = ∠N
∠S = ∠P
∠T = ∠Q
Therefore, the true statement is D. T = Q.

How to calculate intrest
Answer:
You can calculate Interest on your loans and investments by using the following formula for calculating simple interest: Simple Interest= P x R x T ÷ 100, where P = Principal, R = Rate of Interest and T = Time Period of the Loan/Deposit in years.
Formula: Simple Interest=P×r×t where: P=Principal amount; r=Annual interest rate; t=...
Principal Amount: Principal Amount remains constant on Simple Interest
Meaning: Simple Interest is calculated on the Principal Amount for the entire tenure
Calculation: It is easy to calculate Simple Interest
Answer:
To calculate simple interest, you can use a specific formula:
I (interest) = p (principal) x r (rate) x t (time)
Important: Rate is always a decimal, and time must be a compatible unit that matches with the rate (months, years, etc.).

Explanation and Answer:
The graph of y=[tex]x^2[/tex] is a parabola (it looks like a u) that intersects the graph at the origin. These are all shifted variations of that graph, so from that you can figure out their formula by visualizing it.
You can also try substituting numbers into the equations and drawing a graph from that.
Graph A is the y=x^2, shifted to the left, so it becomes [tex]y=x^2+x[/tex]. It's +x because now negative numbers can be gotten from the equation, as compared to before when x^2 gives only positive numbers.
Graph B is [tex]y=x^2+3x[/tex] . Similar to graph A, but now it moves down by more units, because of the 3x.
Graph C is [tex]y=-x^2+2[/tex]. Imaging y=x^2 flipped, it changes from looking like a u to n. That's y=[tex]-x^2[/tex]
Graph D is [tex]y= x^2-x[/tex]. The opposite of Graph A.

Find an
angle in each quadrant with a common reference angle with 216°, from
0°=0<360°
Answer:
Quadrant 1: 36°
Quadrant 2: 144°
Quadrant 3 (Given): 216°
Quadrant 4: 324°
Step-by-step explanation:
A 216° angle in standard position has its terminal side in quadrant 3 since 216° is between 180° and 270°.
216° - 180° = 36°
The reference angle for 216° is 36°
Quadrant 1: 36°
Quadrant 2: 180° - 36° = 144°
Quadrant 3 (Given): 216°
Quadrant 4: 360° - 36° = 324°

[tex]\mathrm{0=20-3y}[/tex]
Now, add 3y to both sides:
