5 Clear 1 Petrov ran 7 laps around a track. Each lap around the track is a distance of mile. What is the total distance Petrov ran in feet? A 9,240 ft 3,017 ft 1,327 ft 36,960 ft
Answer: 36,960 ft
Step-by-step explanation:
Each lap around the track was a mile in distance.
Petrov therefore ran a total of 7 miles.
A mile is 5,280 feet.
If Petrov ran 7 miles in total, this distance in feet is:
= 7 * 5,280
= 36,960 ft

Answer:
x = 15
Step-by-step explanation:
we know that the total degree inside of a triangle made up of 180°
6x + 4x + 2x = 180
12x = 180
x = 15
To find each angle we multiple 4x , 6x, 2x by 15
4(15) = 60°
6(15) = 90°
2(15) = 30°
Answer:
soln,
2x+6x+4x=180°( being s of the angle of triangle is 180°)
12x=180°
X= 180°/12
X= 15
again,
2x=2×15. 6x= 6×15. 4x=4×15
2x=30. 6x=90. 4x=60

What is the end behavior of the graph of the polynomial function f(x) = 3x6 + 30x5 + 75x4?
Answer:
rises to the left and rises to the right
Step-by-step explanation:
The end behavior of the graph of f(x) = 3x⁶ + 30x⁵ + 75x⁴ is that it as x → -∞, y → ∞ and as x → -∞, y→ ∞.
What is a polynomial?A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.
The degree of the polynomial function is 6, which is even, and the leading coefficient is positive, so the end behavior of the graph is as follows:
As x approaches negative infinity, both the x⁶ and x⁵ terms become very large positive numbers, and so the value of the function f(x) approaches positive infinity.
As x approaches positive infinity, both the x⁶ and x⁵ terms become very large positive numbers, and so the value of the function f(x) also approaches positive infinity.
Therefore, the end behavior of the graph of f(x) is that it as x → -∞, y → ∞ and as x → -∞, y→ ∞.

6. A survey was conducted by
asking 120 students in a town
how they traveled to school.
The following pie chart shows
the result of the survey.
What are the number of students
that travel to school by bus?
Best Answer gonna have branliest
Answer:
(a) Since, the highest central angle 120⁰ is of the bus
hence , the most common mode of transport is the bus.
(b) Fraction of children travelling by car =
angle covered by car section
--------------------------------------------
total angle
= 90⁰ 1
--------- = ---------
360⁰ 4
(c) No. of children travelling by car = Fraction of children travelling by car× Total no of children.
1
= 18 = ----- × Total no. of children.......from(b)
4
⇒ Total no of children = 18×4
⇒ Total no of children = 72
(d) Central angle of children who do not take texi = 120⁰ +90⁰ +60⁰+60⁰
⇒ Central angle of students who do not take taxi = 330⁰
⇒ Central angle of students who do take taxi = 360⁰ −330⁰ =30⁰
30⁰
No . of children travelling by taxi = --------- × Total no of children
360⁰
30⁰
⇒ No of children travelling by taxi = --------- × 72 = 6
360⁰
(e) The central angle for students travelling by cycle and those who walk is same.
Thus , the two modes of transport are equal number of children travelling are cycle and walk.

Answer:
1) Zero based on (-16·t - 2) is t = -1/8 second
2) Zero based on (t - 1) is t = 1 second
Step-by-step explanation:
The given functions representing the height of the beach ball the child throws as a function of time are;
y = (-16·t - 2)·(t - 1) and y = -16·t² + 14·t + 2
We note that (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
Therefore, the function representing the height of the beachball, 'y', is y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
The zeros of a function are the values of the variables, 'x', of the function that makes the value of the function, f(x), equal to zero
In the function of the question, we have;
y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
The above equation can be written as follows;
y = (-16·t - 2) × (t - 1)
Therefore, 'y' equals zero when either (-16·t - 2) = 0 or (t - 1) = 0
1) The zero based on (-16·t - 2) = 0, is given as follows;
(-16·t - 2) = 0
∴ t = 2/(-16) = -1/8
t = -1/8 second
The zero based on (-16·t - 2) is t = -1/8 second
2) The zero based on (t - 1) = 0, is given as follows;
(t - 1) = 0
∴ t = 1 second
The zero based on (t - 1) is t = 1 second

m∠R=140 and m∠S=100. Find the m∠T. The diagram is not on the scale.
Answer:
m<T = 20°
Step-by-step explanation:
m<R = 140°
m<S = 100°
The figure given is a kite. The angles formed where two unequal sides meet are always congruent to each other. This means:
m<S = m<U = 100°
Sum of all interior angles of a quadrilateral = 360°
Therefore:
m<T = 360° - (m<S + m<U + m<R)
m<T = 360° - (100° + 100° + 140°) (substitution)
m<T = 20°

Simplify cot θ sec θ.
Answer:
csc θ
Step-by-step explanation:
cot θ sec θ can be substituted by reducing the expression into equivalent parts.
cot θ = (cos θ)/(sin θ)
sec θ = 1/(cos θ)
Reduce these two values to get 1/(sin θ)
This expression can then be changed to csc θ, as it is also equivalent.
The trigonometric expression cot θ × sec θ in the simplified form will be cosec θ.
What is trigonometry?Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The expression is given below.
⇒ cot θ × sec θ
We know that cot θ = cos θ / sin θ and sec θ = 1 / cos θ, then we have
⇒ cot θ × sec θ
⇒ cos θ / sin θ × 1 / cos θ
⇒ 1 / sin θ
We know that 1 / sin θ = cos θ
⇒ 1 / sin θ
⇒ cosec θ
The trigonometric expression cot θ × sec θ in the simplified form will be cosec θ.

A local hamburger shop sold a combined total of 450 hamburgers and cheeseburgers on Thursday. There were 50 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Thursday?
Answer:
250 hamburgers
Step-by-step explanation:
so if there were 50 less cheeseburgers then I would take 50 away from 450 and I would get 400. And then I divided it by 2. And so 200+50 = 250 so 250 hamburgers and 200 cheeseburgers. I hope this helps and I'm not good at explaining. :)

Answer: [tex]\frac{3}{8}[/tex]=[tex]\frac{21}{56}[/tex] [tex]\frac{3}{7}[/tex]=[tex]\frac{24}{56}[/tex]
Step-by-step explanation:
In order to get from 8 to 56, we have to multiply by 7.
We always do the same to the top! 3 multiplied by 7 = 21.
In order to get from 7 to 56, we have to multiply by 8.

Solve these simultaneous equations: 3x = y and x = y - 16
Answer:
x=8
y=24
Step-by-step explanation:
3x=y
x=y-16
Substitute y for 3x
x=3x-16
Add 16 to each side
x+16=3x
Subtract x
16=2x
Divide each side by 2
8=x
y=3x=3×8=24
y=24
Here we have been given with two equations and we have to calculate the values of x and y. So we would be using substitution method for it.
3x = y (Equation No 1)x = y - 16 (Equation No 2)Here we can clearly see that value of y is 3x. So we would substitute it in Equation No 2.
>> x = y - 16
>> x = 3x - 16
>> x - 3x = -16
>> -2x = -16
>> 2x = 16
>> x = 16 / 2
>> x = 8
★ Finding out value of y:-
>> y = 3x
>> y = 3 (8)
>> y = 3 × 8
>> y = 24 [tex] \: [/tex]
