Answer:
3/4 of a liter
Step-by-step explanation:
2 - 5/4
Get a common denominator
2 *4/4 - 5/4
8/4 - 5/4
3/4
The denominator is 4 so rewrite 2 liters as a fraction with 4 as the denominator.
4/4 = 1 so 2 liters would be 8/4
Now subtract:
8/4 - 5/4 = 3/4
There is 3/4 of a liter left.
y = –5x + 30 x = 10 What is the solution to the system of equations? (–20, 10) (10, –20) (10, 4) (4, 10)
Answer:
(10, –20)
Step-by-step explanation:
y = –5x + 30
y = -5(10) + 30
y = -50 + 30
y = -20

A contractor, Susan Meyer, has to haul gravel to three building sites. She can purchase as much as 18 tons at a gravel pit in the north of the city and 14 tons at one in the south. She needs 10, 5, and 10 tons at sites 1, 2, and 3, respectively. The purchase price per ton at each gravel pit and the hauling cost per ton are given in the table below. Susan wishes to determine how much to haul from each pit to each site to minimize the total cost for purchasing and hauling gravel. Pit Hauling cost per Ton at Site Price per ton Site 1 Site 2 Site 3 North $30 $60 $50 $100 South $60 $30 $40 $120 Now suppose that trucks (and their drivers) need to be hired to do the hauling, where each truck can only be used to haul gravel from a single pit to a single site. Each truck can haul 5 tons, and the cost per truck is five times the hauling cost per ton given above. Only full trucks would be used to supply each site.
Required:
Formulate this problem as a transportation problem with two sources and three destinations.

Answer:
y=-0.5x-1
Step-by-step explanation:
To complete the equation, we need the y intercept. The y intercept is at x=0, y=-1
The equation of the line is y = -0.5x - 1.
What is the slope of the line?The slope of the line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
Given,
To determine the equation, we need the y intercept. The y intercept is at x = 0, y = -1
The line passes through the points (0, -1) and (4, -3)
Let
x₁ = 0 y₁ = -1
x₂ = 4, y₂ = -3
∵ Slope m = (y₂ - y₁)/(x₂ -x₁ )
Substitute values in the formula
m = (-3-(-1))/(4-0)
m = (-3+1)/(4)
m = -2/4
m = -1/2
Let the line (y - y₂) = m(x -x₂ )
Substitute the values in the equation,
So, y-(-3) = -1/2(x-4)
y + 3 = -1/2x +2
y = -0.5x + 2 - 3
y = -0.5x - 1
The equation of the line is y = -0.5x - 1.
Thus, the missing number is - 1.

C) y=-2/3x+1
D) 2x+3y=3
Answer:
C, y=-2/3x+1
Step-by-step explanation:
using points (0, 1) and (3, -1) obtained from the graph:
slope = -1-1/3-0 = -2/3
use one of the points above lets take (1, 0) and another point (x,y)
slope = y-0/x-1 = -2/3
y=-2/3x+1

Answer:
English; 12
French; 9
Both; 7
Step-by-step explanation:
28 - 19 = 9, therefore there are only 9 students who can only speak French
28 - 16 = 12, therefore there are only 12 students who can only speak English
12 + 9 = 21, then subtract 21 from the 28 total students
28 - 21 = 7, therefore there are only 7 students who can speak both

Answer:
S8 is 64
Step-by-step explanation:

There are 6 red marbles, 9 blue marbles, and 10 green marbles in a bag.
What is the theoretical probability of randomly drawing a red marble and then a green marble?
10%
9.6%
64%
16%
Answer:
A or B depending on whether replacement takes place
Step-by-step explanation:
Without replacementprobability of getting a red marble=6/25
probability of getting a green marble (considering no replacement of marble drawn has taken place)=10/24
probability of randomly drawing a red marble and then a green marble=(6/25)*(10/24)=0.1=10%
With replacementprobability of getting a red marble=6/25
probability of getting a green marble (considering replacement of marble drawn has taken place)=10/25
probability of randomly drawing a red marble and then a green marble=(6/25)*(10/25)=0.096=9.6%

plot the points (0, -2) (4, 1)
a rectangular plot has 17m length and 14m width. What will be the cost of fencing at a rate of Rs.25 per meter
The fence would be the perimeter of the shape.
Perimeter = 17 + 17 + 14 + 14 = 62 meters.
Multiply the price per meter by total meters:
25 x 62 = 1550
For fencing , we have to find the perimeter of rectangle.
[tex] \large\begin{gathered} {\underline{\boxed{ \rm {\red{Formula \: \: Using \: = \: 2 \: ( \: L + B \: )}}}}}\end{gathered}[/tex]
L denotes length of rectangleB denotes breadth of rectangleL = 17 mB = 14 mSubstuting the valuesPerimeter of rectangle = 2 ( L + B )
Perimeter of rectangle = 2 ( 17 m + 14 m )
Perimeter of rectangle = 2 ( 31 m )
Perimeter of rectangle = 62 m.
Hence, the perimeter of rectangle is 62 m.
For Fencing Cost = perimeter × rate of fencing per metre
Fencing Cost = 62 × 25
Fencing cost = 1,550
Hence, the cost of fencing of a rectangular plot is 1,550
