After 2 week he has used 8 1/2 cups of dog food after 5 week he has used 21 1/4 cups construct a function in the form y =mx+ to represent the amount of dog food used y, after x weeks
Answer:
y = 4.25x
Step-by-step explanation:
Given that:
After 2 week he has used 8 1/2 cups of dog food after 5 week he has used 21 1/4 cups, we can write this in coordinate form (x, y) where;
y is the amount of dog food
x is the time in weeks
The coordinates are (2, 8 1/2) and (5, 21 1/4)
get the slope m:
m = y2-y1/x2-x1
m = (21 1/4 - 8 1/2)/5-2
m = (85/4-17/2)/3
m = (85-34/4)/3
m = 51/12
m = 4.25
Get the intercept c:
Substitute any of the points say (2, 17/2) and m = 51/12 into the equation
y = mx+c
17/2 = 51/12(2) + c
17/2 = 51/6 + c
c = 17/2 - 51/6
c = 51-51/6
c = 0
Get the required equation:
substitute m - 4.25 and c = 0 into y = mx+c
y = 4.25x + 0
Hence the required equation is y = 4.25x
Two types of tickets are sold to a play. Floor seats cost $45 each and balcony seats cost $25 each. A play sells 107 tickets and makes a total of $3,375. How many of each type of ticket are sold?
Answer:
floor seats=35
and the balcony seats =72
Step-by-step explanation:
Step one
given data
let the floor seats be x
and the balcony seats be y
so
45x+25y=3375-------1
x+y= 107----------------2
from 2, x= 107-y
put x= 107-y in 1
45(107-y)+25y=3375
4815-45y+25y=3375
collect like terms
-45y+25y= 3375-4815
-20y=-1440
divide both sides by -20
y=72
put y= 72 in eqn 2
x+72=107
x=107-72
x=35

1) First find the number of buses
Equation:
total students ÷ 60 students per bus = number of buses taken
340 ÷ 60 = 5 buses taken with 40 students left
2) Now find the number of cars taken
Equation:
students left ÷ 5 students per car = number of cars taken
40 ÷ 5 = 8 cars taken with 0 students left
So your answer is 8 cars and 5 buses.

On a map of the United States, the distance between New York City and Nashville, TN is 2.5 inches. In real life, the distance is 880 miles. What is the scale on the map? (miles/inch) *
Answer: Rounded: 350 miles/inch
Exactly 352 miles per inch.
Step-by-step explanation: Divide the miles by the inches to find miles per inch.
880/2.5 = 352.
It would make sense to round that to say the scale is 350 miles per inch.
One inch represents 350 miles

Which inequalities correctly show the relationship between the numbers 13, −4, and −17?
Answer:
13 > -17 < -4
Step-by-step explanation
13 = postive number
-17 and -4 = negtive.
13 is greater than -17
Since negtive is oppistie of postive it goes backwards.
So -4 is greater than -17

a motorboat moves across a lake at a constant speed. when it begins it from the shore. after 9 minitues it is 14 km from the shore. which function decribes the motorboat distance from the shore?
a. y= 4x + 50
b. y= -4x + 50
c. y= 9x + 50
d. y= -9x + 50
Answer:
Answer:
The function describes the motorboat's distance from the shore
Step-by-step explanation:
A motorboat moves across a lake as a constant speed. when it begins, it is 50 km from the shore
After 9 minutes, it is 14 km from the shore.
So, rate of change =
Negative sign shows that there is decrease in distance per minute
The rate of change of distance is 4 km / minutes
General equation : y = mx+c
Where m is the slope and c is the constant
Substitute the values in the equation :
y=-4x+50
Where y is the final distance and x is the minutes
So, Option C is true
Hence The function describes the motorboat's distance from the shore

In AUVW, mZU = (92 – 8), m_V = (2x + 2)", and m_W = (3x + 4)
Find m2V.
Answer:
[tex]m\angle V=30^\circ[/tex]
Step-by-step explanation:
Angles in a Triangle
The sum of the angles in a triangle is 180°. We are given the measure of all angles in the triangle:
[tex]m\angle U=9x-8[/tex]
[tex]m\angle V=2x+2[/tex]
[tex]m\angle W=3x+4[/tex]
Thus:
9x - 8 + 2x + 2 + 3x + 4 = 180
Simplifying:
13x - 2 = 180
Adding 2:
13x = 182
Dividing by 13:
x = 182/13 = 14
x = 14
Now we calculate:
[tex]m\angle V=2x+2=2*14+2=28+2 =30[/tex]
[tex]\mathbf{m\angle V=30^\circ}[/tex]

Find the median of 1.4, 0.9, 2.4, 3.5, 2
Step-by-step explanation:
We arrange the numbers in increasing order:
0.9, 1.4, 2, 2.4, 3.5
Since there are five terms, the median is the third term, which is 2.
The median of the given data set is 2.
What is a median?The median is the middle number in a sorted, ascending or descending list of numbers.
Given is a data set, 1.4, 0.9, 2.4, 3.5, 2, we need to find median,
Rearranging the data from lowest to greatest,
0.9, 1.4, 2, 2.4, 3.5
Since, the median is the middle most value in a data, therefore, the middle most value of the given data is 2.
Therefore, we can say the median is 2.
Hence, the median of the data is 2.

Max is building a treehouse. He has a piece of wood that is 6 ft long. How many 1/3 ft pieces of wood can you cut
Answer:
18 pieces
Step-by-step explanation:
Max is building a treehouse. He has a piece of wood that is 6 ft long. How many 1/3 ft pieces of wood can you cut?
From the above question, we can deduce that:
1 piece of wood = 1/3ft
Hence:
1/3 = 1 piece of wood
6 ft = x
Cross Multiply
1/3ft × x = 6 ft × 1
x = 6 / 1/3
x = 6 × 3
x = 18 pieces
Hence, you can cut 18 (1/3 ft )pieces of wood .
Choose the correct label for the solution to each system of equations from the drop-down menus.
Answer: left one is no solution and right one is infinite solutions
explanation: the left one the lines don’t touch at all which has no solution and the right one means that both lines are on top of each other
In the first graph, there are ''No solution.''
In the second graph, there are ''Infinitely solution.''
What is Number line?Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
Now,
For the first graph;
In this graph we can see that there are two parallel lines.
We know that two parallel lines never intersect.
Therefore, we never get any common coordinate for this.
Thus, This system has ''No solutions.''
For the second graph;
There is a single straight line is given.
We know that each point be the solution of this line and a line contains infinitely many pints.
Thus, it has ''infinitely many solutions.''
Hence, The first graph is shows the ''No solution'' and the second graph is shown the ''infinitely many solutions.''

A circle has equation x2 + y2 = 25
The circle passes through the points A, B, C and D.
Complete the coordinates for A, B, C and D.
A. (5,_)
B.(_,-5).
C. (_,0)
D(0,_)
Answer: A. (5; 0), B. (0; - 5), C. (-5; 0), D. (0; 5).
Step-by-step explanation:
A. (5; _) [x = 5; y - ?]
x² + y² = 25
5² + y² = 25
25 + y² = 25
25 + y² - 25 = 25 - 25
y² = 0
y = 0
A. (5; 0)
B. (_; -5) [x - ?; y = -5]
x² + y² = 25
x² + (- 5)² = 25
x² + 25 = 25
x² + 25 = 25
x² + 25 - 25 = 25 - 25
x² = 0
x = 0
B. (0; - 5)
C. (_; 0) [x - ?; y = 0]
x² + y² = 25
x² + 0² = 25
x² + 0 = 25
x² = 25
x = ± √25 = ± 5
C. (-5; 0) or (5; 0)
Point A has coordinates (5; 0), which means that
point C has coordinates (-5; 0).
D. (0; _) [x = 0; y - ?]
x² + y² = 25
0² + y² = 25
0 + y² = 25
y² = 25
y = ± √25 = ± 5
D. (0; - 5) or (0; 5)
Point B has coordinates (0; -5), which means that
point D has coordinates (0; 5).
An empty box weighs 200 g the boxes filled with party goody bags and now it weighs 6.2 kg each goodie bag weighs 100 and grams work out how many goody bags are inside the box
Answer:
60 goody bags
Step-by-step explanation:
1 kg = 1000 g
6.2 kg = 6,200 g
Empty box = 200 g
Box + goody bags = 6,200 g
Weight of Goody bags = Box + goody bags - empty box
= 6,200g - 200g
= 6,000 grams
Each goody bag = 100 g
how many goody bags are inside the box
Number of goody bag in the box = total weight of goody bag / weight of each goody bag
= 6,000 grams / 100 grams
= 60 goody bags
There are 60 goody bags in the box
