On an airplane, the passengers may have chicken, vegetable or tomato soup
Half of the passengers choose chicken soup
A third of the passengers choose tomato soup.
(a) What fraction of the passengers choose vegetable soup?
There are 240 passengers on the airplane.
(b) How many passengers choose vegetable soup?
Answer:
1/6 and 40
Step-by-step explanation:
for 1/6 you can get the answer by getting 1/2 chicken = 3/6 then 1/3 tomato soup = 2/6 and you have 1/6 left which will be the answer.
For the number of people, 1/6 is equal to 40 because 240 divided by 6 equals 40
Add the following (-3) and(-5) using number line.
Answer:
hope it will help you. ans is -8
Step-by-step explanation:
SOLUTION
Starting at zero on the number line facing positive direction and move 3 steps backward reaching -3.
-9-8
-6-5-4-3-2-1
0
Then we move 5 steps backward to represent -5 and reach -8.
(-3) + (-5) = -8

What is the slope of the line for BOTH graphs? Are the slopes the same or different?
PLS HELP MEEE
Answer:
both are -10
Step-by-step explanation:
#1
x1 y1 x2 y2
1.5 180 6 135
(Y2-Y1) (135)-(180)= -45 ΔY -45
(X2-X1) (6)-(1.5)= 4.5 ΔX 4.5
slope= -10
B= 195
Y =-10X +195

AB = 2x – 17, AC = 14, and BC = x + 1.
Find x.
9514 1404 393
Answer:
x = 10AB = 3BC = 11Step-by-step explanation:
If B lies between A and C on a line segment, then ...
AB +BC = AC
(2x -17) +(x +1) = 14
3x = 30 . . . . . . . . . . . . . add 16, collect terms
x = 10 . . . . . . . . . . . divide by 3
AB = 2(10)-17 = 3

find the slope of the line that is perpendicular to the line graphed in the figure
Answer:
- [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m = [tex]\frac{1-(-4)}{1-0}[/tex] = [tex]\frac{1+4}{1}[/tex] = 5
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{5}[/tex]

Adjacent sides of Figure 1 are perpendicular. Four sides of Figure 1 are removed to form Figure 2. What is the total length, in units, of the segments in Figure 2?
Answer:
19
Step-by-step explanation:
Here ( left and right) side 8 and 6 are same in both
in fig 1 base side is 1 +2 + 1 =4
so in figure 2 it will be also 4
and at last only 1 unit in fig 1 ( upside) is taken in figure 2
so total addition is...
8 + 6 + 4 + 1
= 19

solve: 24x power 3 -26x power 2 +9x -1=0
Answer:
hiiiiiiii
Step-by-step explanation:
hiiiiiiiii
Answer:
x = 1/2 , x = 1/4 , x = 1/3
Step-by-step explanation:
Factor the following equation --> 24x^3 — 26x^2 + 9x — 1 = 0
You will get ----> (2x - 1) (4x - 1) (3x - 1) = 0
Now make all the above expressions = 0 and solve.
2x - 1 = 0 4x - 1 = 0 3x - 1 = 0
+1 +1 +1 +1 +1 +1
------------------ ------------------ ------------------
2x = 1 4x = 1 3x = 1
/2 /2 /4 /4 /3 /3
------------------- ------------------- ----------------------
x = 1/2 x = 1/4 x = 1/3

if 6x=9y find the value of x:y.
Answer:
A complete angle is one which measures 360∘360∘.
The three angles
6x+20∘,9y+30∘,3z+40∘6x+20∘,9y+30∘,3z+40∘
add up to 360∘360∘, as per the question.
6x+20∘+9y+30∘+3z+40∘=360∘6x+20∘+9y+30∘+3z+40∘=360∘
⟹3(2x+3y+z)+90∘=360∘⟹3(2x+3y+z)+90∘=360∘
⟹3(2x+3y+z)=270∘⟹3(2x+3y+z)=270∘
⟹2x+3y+z=90∘⟹2x+3y+z=90∘
This is the required relation.

Rowena sells a dress for $42.60 after making a profit of 20% on the cost price.
Calculate the cost price.
20
$ ...................................................
Answer:
$35.50
Step-by-step explanation:
With a 20% profit then $42.60 represents 120%
We require to find the cost price represented by 100%
Divide the amount by 120 to find 1% then multiply by 100, that is
cost price = [tex]\frac{46.60}{120}[/tex] × 100 = $35.50
