Han used 1 1/2 gallons of paint to paint 3/5 of a shed. How many gallons of paint will it take to paint the whole shed? Write a multiplication equation or a division equation to represent this situation then find the answer. Show your reasoning
Answer:
2 gallons
Step-by-step explanation:
If Han used 1 1/2 gallons of paint to paint 3/5 of a shed, this can be expressed as;
1 1/2 gallons = 3/5 of the shed
3/2gallons = 3/5 of the shed
To find the number of gallons that will paint the whole shed, we will say;
x gallons = 1 shed
Divide both expressions
3/2/x = 3/5
3/2x = 3/4
2x * 3 = 3*4
6x = 12
x = 12/6
x = 2
Hence 2 gallons will be needed for the whole shed
Evaluate ƒ(x) when x = 3. 6x^2+2
Answer: f(x)=56
Step-by-step explanation:
We are given the equation f(x)=6x²+2. Since we are asking for x=3, we can plug that into the equation and solve.
f(3)=6(3)²+2 [exponent]
f(3)=6(9)+2 [multiply]
f(3)=54+2 [add]
f(3)=56
Now, we know that f(x)=56 when x=3.
The depth of an underwater camera on a cable anchored to the sea floor is proportional to the time. The table records the time in seconds (s) and depth in meters (m) of the camera. What are the missing values in the table?
Answer:
20=-1
60=-3
100=-5
240=-12
Step-by-step explanation:
divide time and depth by 20
When time is 20 the depth is -1, when time is 60 the depth is -3 and time is 240 the depth is -12.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
The depth of an underwater camera on a cable anchored to the sea floor is proportional to the time.
From the table let us take the values of time and depth which both are given.
Time=100 and depth is -5.
From this we can find the other values.
Depth=-1 when time is x
100/-5=x/-1
100=5x
Divide both sides by 5
x=20
So when time is 20 the depth is -1.
Now we have to find the depth when time is 60.
60/x=100/-5
-300=100x
x=-3
So when time is 60 the depth is -3.
Now we have to find the depth when time is 240.
240/x=100/-5
-1200=100x
Divide both sides by 100
x=-12
when time is 240 the depth is -12.
Hence, when time is 20 the depth is -1, when time is 60 the depth is -3 and time is 240 the depth is -12.

Answer:
1 round = 220 meter wire
2 rounds = 440 meter wire
3 rounds = 660 meter wire
Step-by-step explanation:
Given that:
Perimeter of squared garden = 220m
As the perimeter is given, the length of the wire would be calculated with it.
The length of wire to fence with 1 round = 220 * 1 = 220m
The length of wire to fence with 2 rounds = 220 * 2 = 440m
The length of wire to fence with 3 rounds = 220 * 3 = 660m
Hence,
1 round = 220 meter wire
2 rounds = 440 meter wire
3 rounds = 660 meter wire
A video game is on sale for 20% off. The sale price of the game is $35.00. How much did the game ORIGINALLY cost?
Answer:
$43.75
Step-by-step explanation:
To find how much the game would have been 20% off from 43.75, you would have needed the expression
43.75*0.8
So to go from 35 to 43.75, you need the expression
35/0.8.
This expression in simpler terms means What is 38, 80% of?
That is how we get 43.75.
35/0.8 = 43.75.

Together a chair, a table, and a lamp cost $562. The chair costs 4 times as much as the lamp, and the table costs $23 less than the chair. Find the cost of the table.
Answer:
Cost of table is $237
Step-by-step explanation:
Cost of chair, table and lamp = $562
Cost of lamp = x
Cost of chair = 4x (The chair costs 4 times as much as the lamp)
Cost of table = 4x-23 (the table costs $23 less than the chair.)
We need to find the cost of table.
We know that:
Cost of chair, table and lamp = $562
We can write:
[tex]x+4x+4x-23=562[/tex]
First, we need to find value of x by solving the equation.
[tex]x+4x+4x-23=562\\9x=562+23\\9x=585\\x=\frac{585}{9}\\x=65[/tex]
So, we get x = 65
Now, we can find cost of table:
We are given:
Cost of table = 4x-23
Cost of table = 4(65)- 23 = 237
So, Cost of table is $237

A deli sells 2 hot dogs for $2.50. What is the constant of proportionality of dollars per hot dog?
Answer:
$1.25 per hot dog
Step-by-step explanation:
Since we have given that
A deli sells 2 hot dogs for $2.50
i.e.
Cost of 2 hot dogs = $2.50
And we need to find the constant of proportionality of dollars per hot dog, for which we'll use unitary method.
So,
Cost of 1 hot dog is given by
2.50/2=$1.25
So, Cost of per hot dog is $1.25.

Find the slope of the line that contains the points (1, 6) and (10, -9)
Answer:
-15/9
Step-by-step explanation:
The slope is the steepness of the line. To find it, you divide how far up it goes by how far across it goes. This equals the diagonal incline. To find it with points, you find the difference between the y values and divide that by the difference in the x values!
-9-6=-15
10-1=9
-15/9=-15/9
This slope means that for every nine units the line goes across, it goes down 15 units!

ON wednesday Eddy goes to a velodrome to train. He cycles the first lap of the track in 25 seconds. Each lap Eddy cycles takes him 1.6 seconds longer thatn the previous lap.
Required:
a. Find the time in seconds, Eddy takes to cycle his tenth lap 2
b. Eddy cycles his last lap in 55.4 seconds. Find how many laps he has cycled on wednesday.
c. Find the total time in minutes, cycled by Eddy on Sunday.
Answer:
Step-by-step explanation:
The data of timing for each lap will form a arthmetic progression ( AP ) with first term as 25 s and common difference of 1.6 s .
a )
first term a = 25
common difference d = 1.6 .
10 th term of the series can be given by following formula
a₁₀ = 25 + ( 10-1 ) x 1.6
= 25 + 1.6 x 9
= 39.4 s
b )
Let n th be the last lap
a(n) = a + ( n-1 ) x d
55.4 = 25 + ( n- 1 ) x 1.6
n - 1 = 19
n = 20 .
c )
sum of all the term of AP
=( first term + last term ) x no of term / 2
= (25 + 55.4 ) x 20 / 2
= 804 s .
= 804 / 60 min
= 13.4 min .
