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
Answers
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.

Answers
Answer:
105°
Step-by-step explanation:
An angle is created by West First Street and South Main Street. Call this angle <1. m<1 = x, an unknown.
An angle is created by West First Street and North Main Street. Call this angle <2. This angle measures 30° less than <1, so it measures x - 30.
The two angles form a linear pair, so they are supplementary.
The sum of the measures of supplementary angles is 180 deg.
x + x - 30 = 180
2x - 30 = 180
2x = 210
x = 105
m<1 = 105
The angle we are looking for, created by North Main Street and East First Street is vertical to angle 1, so it is congruent to angle 1.
Answer: 105°

I plugged the table into Desmos and I determined the slope and intercept from that.
(y2-y2)/(x2-x1)
plug in two points from the table:
(7- -5)/(2- -1) = 12/3 = 4
the slope is 4
plug in one of the points and the slope into point slope form:
y+5 = 4 (x+1)
solve to find slope intercept form:
y+5 = 4x + 4
y = 4x - 1
answer: y = 4x - 1

Subtract 10, divide by 7
Step-by-step explanation:
You’d subtract 10 from both sides to remove 10 from the left side of the equation.
Then you’d divide by 7 on both sides to isolate the variable (m).
