a coffee shop used 30% more sugar this month than last month. if the coffee shop used 728 kilograms of the sugar this month, how much did it use last month
It used 560 kilograms of sugar last month
Step-by-step explanation:
The given is:
A coffee shop used 30% more sugar this month than last monthThe coffee shop used 728 kilograms of the sugar this monthWe need to find how much it used last month
Assume that the coffee shop used x kg sugar the last month
∵ The coffee shop used x kilogram of sugar last month
∵ It used 30% more sugar this month than last month
- Find the value of 30% of x and add it to x to find how many
kilograms it used for this month
∵ 30% of x = [tex]\frac{30}{100}[/tex] × x = 0.3 x
∴ It used this month = x + 0.3 x
∴ It used this month = 1.3 x kg
∴ The coffee shop used 1.3 x kilograms of sugar this month
∵ The coffee shop used 728 kilograms of the sugar this month
- Equate 1.3 x by 728 to find x
∴ 1.3 x = 728
- Divide both sides by 1.3
∴ x = 560
It used 560 kilograms of sugar last month

Which ordered pair is a solution to the system of linear equations Negative 4 x + y = 8 and x minus 5 y = 17?
Answer:
(-3, -4).
Step-by-step explanation:
-4x + y = 8
x - 5y = 17 Multiply this by 4:
4x - 20y = 68 Add this to the first equation:
-19y = 76
y = 76/-19
y = -4.
Plug this into the second equation:
x - 5(-4) = 17
x = 17 - 20
x = -3.
CHECK this result in equation 1:
-4(-3) + -4 = 8
12 - 4 = 8
8 = 8 <------ OK.
The solution of the given system of equations is [tex]y=-4[/tex].
Important information:
[tex]-4x+y=8[/tex] ...(i)[tex]x-5y=17[/tex] ...(ii)System of equations:Multiply both sides by 5 in equation (i).
[tex]-20x+5y=40[/tex] ...(iii)
Add equation (ii) and (iii).
[tex]-19x=57[/tex]
[tex]x=\dfrac{57}{-19}[/tex]
[tex]x=-3[/tex]
Substitute [tex]x=-3[/tex] in (i).

Find the sum of the whole numbers from 1 to 960
Step-by-step explanation:
A quick way to do this sort of question:
First add the last number and the first number:
1 + 960 = 961
Then divide the total amount of numbers by 2.
960 ÷2 = 480
Now multiply these two numbers together:
961 × 480 = 461280
The sum of the whole numbers from 1 to 960 can be found using the formula for the sum of an arithmetic series. By substituting the values into the formula, we find that the sum is 461280.
Explanation:The sum of the whole numbers from 1 to 960 can be found using a simple formula for the sum of an arithmetic series. The formula is S = n/2 * (a + l), where 'n' is the number of terms, 'a' is the first term, and 'l' is the last term.
In this case, 'n' is 960 (there are 960 terms from 1 to 960), 'a' is 1 (the first term), and 'l' is 960 (the last term).
Plug these values into the formula to get: S = 960/2 * (1 + 960) = 480 * 961 = 461280. So, the sum of the whole numbers from 1 to 960 is 461280.

angle K and angle L are complementary angels. If the measurement of angle K =(3x+3) and the measurement of angle L =(10x-4).what is the measure of each angle
The measurement of two angles is 24° and 66°
Step-by-step explanation:
First of all, let us define complementary angles
The angles whose sum is 90° are called complementary angles
Given
∠K = (3x+3)
∠L = (10x-4)
According to the definition,
[tex]K+L = 90\\3x+3 + 10x-4 = 90\\13x -1 = 90\\13x-1+1 = 90+1\\13x = 91[/tex]
Dividing both sides by 13
[tex]\frac{13x}{13} = \frac{91}{13}\\x = 7[/tex]
So,
∠K = 3x + 3 = 3(7) + 3 = 21+3 = 24°
∠L = 10x - 4 = 10(7) -4 =70 -4 = 66°
Hence,
The measurement of two angles is 24° and 66°

a recipe for lemonade calls for 2 cups of sugar for every 1/2 cup of lemon juice. How many cups of sugar would be needed if you had 3 cups of lemon juice?
Answer: 12cups of sugar
Step-by-step explanation:
2cups of sugar = 1/2cup of memo
Xcups of sugar =3cups of lemon
X = 6÷ 1/2
= 12
Answer:
12 cups sugar
Step-by-step explanation:
there are a couple ways to do this...by unit rate or a proportion...
2 cups of sugar for every 1/2 cup of lemon juice
2 / (1/2) = 2 * 2 = 4.....the unit rate is 4/1....or 4 cups of sugar for every 1 cup of lemon.
so if u have 3 cups of lemon, and 1 cup of lemon = 4 cups of sugar, then 3 cups of lemon would equal (4 * 3) = 12 cups of sugar
or set it up as a proportion...
2 cups sugar to 1/2 cup lemon = x cups sugar to 3 cups lemon
2 / (1/2) = x / 3....cross multiply
(1/2)(x) = (3)(2)
1/2x = 6
x = 6 * 2
x = 12 cups sugar
either way u choose to do it will result in the same answer.

What is y = 4 * (0.8) ^ t
The function y = 4 * (0.8)^t is an exponential decay function, representing the decrease of a quantity over time, with y being the value at time t. To find y at any given t, substitute t into the equation and calculate the result.
Explanation:The given function y = 4 * (0.8)^t is an exponential decay function, where y represents the value of the function at time t, the number 4 is the initial value of the function when t = 0, and 0.8 is the decay factor relevant for each time unit. This type of function is often used in contexts such as radioactive decay, depreciation of value over time, or population decrease in a closed environment, where some quantity decreases by a consistent percentage over equal time intervals.
To solve for y at a given time t, simply substitute the value of t into the function and evaluate the exponential expression. It is important to use a calculator or software tool to evaluate the exponential term accurately when t is not a round number.

| 3y - 3x = -12
Answer:
x=5/2, y=-3/2. (5/2, -3/2).
Step-by-step explanation:
2=2y+5
3y-3x=-12
--------------
2-5=2y
2y=-3
y=-3/2
3(-3/2)-3x=-12
-9/2-3x=-12
3x=-9/2-(-12)
3x=-9/2+12
3x=-9/2+24/2
3x=15/2
x=(15/2)/3
x=(15/2)(1/3)
x=15/6=5/2
The solution for the system of equations is x = -5/2 and y = -3/2.
To solve the system of equations given, one can use substitution or elimination methods. The first equation 2= 2y + 5 can be rearranged to solve for y:
2y = 2 - 5
2y = -3
y = -3/2
Using the second equation 3y - 3x = -12, we substitute y with -3/2 to solve for x:
3(-3/2) - 3x = -12
-9/2 - 3x = -12
3x = -12 + 9/2
3x = -15/2
x = -15/6
x = -5/2
Therefore, the solution for the system of equations is x = -5/2 and y = -3/2.

Andrew and Karleigh each run for 1 hour. Which statement explains who ran a greater distance?
Answer: The one who ran at the greater Average Speed in 1 hour ran the greater Distance.
Step-by-step explanation:
Speed (S) is the ratio of the distance (D) covered to the time (t) taken.
That is, S = D/t
Suppose Andrew ran a distance D1 in 1 hour (3600 seconds) at a Speed, say S1, we have
S1 = D1/t
We can then say he ran a distance
D1 = t × S1
= 3600S1
Similarly, let's say Karleigh ran a distance
D2 = t × S2
= 3600S2
Let us compare these two, you will notice that the bigger number between S1 and S2 is going to determine the bigger number between D1 and D2.
Let's choose random numbers for S1 and S2 for clarity, say S1 = 5, S2 = 10
D1 = 3600 × 5
= 18000
D2 = 3600 × 10
= 36000
This makes D2 bigger than D1.
I hope this is clear.
Answer:
Karleigh ran a greater distance. The slope of the line described by the data in her table increased at a rate of 1/10 mile per minute compared to Andrew’s 1/12 mile per minute.

$37.50 decreased by 4% =
Answer:
$36
Step-by-step explanation:
The original value is $37.50 so that is 100%.
A decrease of 4% from original value means that you are finding 96% of the value, since 100% -4%= 96%
So the new value is 37.50/100 ×96= $36
This is because:
100% ----- $37.50
1% --------- $0.375
96% ------- $36
or taking 96% of original value would be
96/100 × $37.50= $36
Which would give you the same answer

Step-by-step explanation:
An apartment building currently has rented x apartments with two occupants and 16 apartments with one occupant. The apartment building has 92 total occupants.
2× + 16 =92
How many double-occupancy apartments are currently rented?
The currently rented double-occupancy apartments are 38 apartments.
Step-by-step explanation:
An apartment has rented x apartments with two occupants and 16 apartments with one occupant and the total occupants were 92, these can be written in the equation as
[tex]2x+16=92[/tex]
To find the number of double occupancy apartments that are rented, we need to solve the equation and find the value of x.
[tex]2x+16=92[/tex]
Subtracting 16 from both sides of the equation,
[tex]\begin{aligned}&2 x=92-16\\&2 x=76\end{aligned}[/tex]
Dividing both sides by 2, we get,
[tex]\begin{aligned}\frac{2 x}{2} &=\frac{76}{2} \\x &=38\end{aligned}[/tex]
Thus, there are 38 double-occupancy apartments are currently rented.
The correct answer is that there are 38 double-occupancy apartments currently rented.
To solve the problem, we start with the given equation that represents the total number of occupants in the apartment building:
[tex]\[ 2x + 16 = 92 \][/tex]
This equation takes into account that each double-occupancy apartment (x) houses two occupants, and there are also 16 single-occupancy apartments. We want to find the value of x, which represents the number of double-occupancy apartments.
First, we subtract 16 from both sides of the equation to isolate the term with x:
[tex]\[ 2x + 16 - 16 = 92 - 16 \][/tex]
[tex]\[ 2x = 76 \][/tex]
Next, we divide both sides of the equation by 2 to solve for x:
[tex]\[ \frac{2x}{2} = \frac{76}{2} \][/tex]
[tex]\[ x = 38 \][/tex]
Therefore, there are 38 double-occupancy apartments currently rented in the building. This matches the correct answer provided at the beginning.
