A student uses the equation tangent theta = startfraction s squared over 49 endfraction to represent the speed, s, in feet per second, of a toy car driving around a circular track having an angle of incline theta, where sine theta = one-half. to solve the problem, the student used the given value of sine theta to find the value of tangent theta and then substituted the value of tangent theta in the equation above to solve for s. what is the approximate value of s, the speed of the car in feet per second? 5.3 7.5 9.2 28.3
The approximate value of the speed of the car in feet per second is A. 5.32 ft/s.
How to find the spped?An equation is an expression that shows the relationship between two or more numbers and variables. In this case, tan(θ) = s² / 49
sinθ = 1/2
θ = sin⁻¹ (0.5) = 30⁰
tan(30) = s² / 49
s = 5.32 ft/s
Therefore, the approximate value of the speed of the car in feet per second is 5.32 ft/s.

what is the shaded part of the digestive (use 3. 14 as estimate for pi)
35 points for right answer
Answer:
Option A
Step-by-step explanation:
Area of shaded region
Square:
Side = 12 m
Area of square = Side *side
= 12 *12
= 144 square m
Circle:
diameter = side of the square
= 12 m
r = 12/2
r = 6 m
Area of circle = πr²
= 3.14 *6 * 6
= 113.04 m²
Area of the shaded part = area of square - area of circle
= 144 - 113.04
= 30.96 m²

WILL GIVE BRAINLIEST (08.03) Consider the following pair of equations:
y = 3x + 3
y = x − 1
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answer:
(- 2, - 3 )
Step-by-step explanation:
y = 3x + 3 → (1)
y = x - 1 → (2)
substitute y = 3x + 3 into (2)
3x + 3 = x - 1 ( subtract x from both sides )
2x + 3 = - 1 ( subtract 3 from both sides )
2x = - 4 ( divide both sides by 2 )
x = - 2
substitute x = - 2 into either of the 2 equations and evaluate for y
substituting into (2)
y = - 2 - 1 = - 3
solution is (- 2, - 3 )
Answer:
y = -3, x = -2
Step-by-step explanation:
1. Substitute "y = x - 1" in for y in the first equation:
x - 1 = 3x + 3
2. Isolate x:
x = 3x + 3 + 1
3. Combine like terms:
-2x = 4
4. Solve for x:
-2x/-2 = 4/-2
x = -2
5. Solve for y with substitution (using the second equation):
y = -2 - 1
y = -3

Please answer. Correct answer will be brainliest.
Answer:
161
Step-by-step explanation:
It's a system of equations, let's solve it step-by-step!
Equation: [3 * 2^5 + 13 * (-2)] + 7[8 - (4 - 9)]
2^5 = 32
so we have [3 * 32 + 13 * (-2)] + 7[8 - (4 - 9)].
3 * 32 = 96
so we have [96 + 13 * (-2)] + 7[8 - (4 - 9)].
13 * (-2) = -26
so we have [96 - 26] + 7[8 - (4 - 9)].
96 - 26 = 70
so we have 70 + 7[8 - (4 - 9)].
4 - 9 = -5
so we have 70 + 7[8 - (-5)].
8 - (-5) = 13 (the signs cancel out)
so we have 70 + 7[13].
7 * 13 = 91
so we have 70 + 91.
70 + 91 = 161
Therefore our answer is 161.

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Alexander sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
8 visitors purchased no costume.
340 visitors purchased exactly one costume.
28 visitors purchased more than one costume.
If next week, he is expecting 600 visitors, about how many would you expect to buy more than one costume? Round your answer to the nearest whole number.
Answer:
45 people
Step-by-step explanation:
1) Add all of the origanal visitors (376)
2) Find the ratio (28/376) = 0.0744
3) Either 28/376 * 600 OR 0.0744 * 600 (I would recomend the fraction for more accurate answers, but because it says to round to the nearest whole number either will work, but you should still use fraction)
4) 44.6908

The radius of a circle is 7 m. Find its circumference in terms of
π
π.
[tex]circumference = 2 \times \pi \times r[/tex]
[tex]circumference = 2 \times \pi \times 7[/tex]
[tex]circumference = 14\pi[/tex]
Answer:
14π
Step-by-step explanation:
Given:
Radius of circle = 7 mTo determine the circumference of the circle, we need to use the formula 2πr, where "r" represents the radius of the circle.
Substitute the radius in the formula:
[tex]\implies 2\pi (r) = \text{Circumference}[/tex]
[tex]\implies 2\pi (7) = \text{Circumference}[/tex]
Simplify the circumference:
[tex]\implies 2\pi (7) = \text{Circumference}[/tex]
[tex]\implies 14\pi = \text{Circumference}[/tex]
Thus, the circumference is 14π.

A bus travels 25 yards in 1 second. How many miles will it travel in 2 hours?
Answer:
102 miles
Step-by-step explanation:
In 2 hours there are 7200 seconds ([tex]60*60 = 3600 * 2 = 7200[/tex])
In one second the bus travels 25 yards, so; [tex]7200 * 25 = 180,000 yards[/tex]
Converting yards to miles is: [tex]x (yards) / 1760[/tex]
[tex]180000/1760 = 102.2727272...[/tex]
∴ The bus will travel 102 miles in 2 hours.

The graph that represents the solution set for x > -6 is Graph D.
What is Number line?In mathematics, a number line is a straight line that represents numbers and their relative positions. It is a visual representation of the real number system.
To find the solution set for the inequality 2x + 3 > -9,
2x + 3 > -9
Subtract 3 from both sides:
2x > -12
Divide both sides by 2:
x > -6
The solution set for the inequality is x > -6, which means that x is greater than -6.
So, Among the given graphs, the graph that represents the solution set for x > -6 is Graph D.
