Answer:
4.4 km/h
Step-by-step explanation:
From the graph you can see she was at the shop after 30 minutes. If you travel 2.2 km in 30 minutes, your speed is 2.2 / 0.5 = 4.4 km/h
So the trick is to express the 30 minutes as 1/2 hour.
Answer:
4.4 km/h
Step-by-step explanation:
At the store you want to buy a bunch of 3d printed Christmas gifts for your family. Each large tree costs $4.50 , and each small tree costs $2.25, If you buy 4 large trees, and can spend a total of $50. Write and solve an inequality for number of small trees (s) you can buy
We know that each large tree costs $4.50, and each small tree costs $2.25. If you buy 4 large trees, that means you will spend 4 * $4.50 = $<<4*4.5=18>>18 on large trees.
If you can spend a total of $50, then you have $50 - $18 = $<<50-18=32>>32 to spend on small trees.
The total cost of the small trees will be s * $2.25, where s is the number of small trees you buy.
To find the maximum number of small trees you can buy, we can set this expression equal to $32 and solve for s:
s * $2.25 = $32
s = $32 / $2.25
s = 14.22
Since you can't buy a fraction of a tree, the maximum number of small trees you can buy is 14.
Answer:
If each large tree costs 4.50 and you need to buy 4, then 4 x 4.50 = $18.00 leaving you with $32.00. With these 32 dollars left, you can now buy 14 small trees, still being left with a remainder of 0.50$.

Answer:
45 inches
Step-by-step explanation:
The perimeter of the picture before scaling is:
P = L+W+L+W
P = 4+5+4+5
P = 18
Multiply the perimeter by the scale factor.
P = 18 * 2.5
P =45
And it's not f'(x) = (0.1x - 1)^2 + 1)
Answer:
A
Step-by-step explanation:
To reflect a function over the x-axis, we multiply the function by -1. So, if f(x) is the original function, then -f(x) is the function across the x-axis.
To reflect a function over the y-axis, we multiply the inside of the function by -1. So, if f(x) is the original function, then f(-x) is the function across the x-axis.
We have:
\(f(x)=(x-1)^2+1\)
Then:
\(f(-x)=(-x-1)^2+1=f ^\prime(x)\)
We can see that the choice that resembles this is A. If we let:
\(f(-4x)=(-4x-1)^2+1\)
This is a reflection over the y-axis followed by a horizontal compression by a factor of 4.
Hence, our answer is A.

Answer: 5.4n to the power of 5.
Step-by-step explanation: Remove parentheses. 4n 5 +3.5n 5 −2.1×n 5
You get 5.4n to the power of 5
Answer: 5.4n^5, the 3rd option.
Step-by-step explanation:
The first step to solve this is to use the distributive property to change this equation into: 4n^5 + 3.5n^5 - 2.1n^5.
Then, you add 4n^5 + 3.5n^5 which is 7.5n^5.
The last step is to subtract 2.1n^5 from 7.5n^5 which is 5.4n^5.

If 1/2-1/3 = x , then x =
Answer:
1/6
Step-by-step explanation:
1/2 - 1/3 = x
To make the common denominator, you need to make both denominators 6. 1/2 turns into 3/6, 1/3 turns into 2/6, and 3/6 - 2/6 is 1/6.
Answer: \(\frac{1}{6}\)
Step-by-step explanation:
Since \(\frac{1}{2}-\frac{1}{3} = x\), \(x=\frac{1}{2}-\frac{1}{3}\)
Then we are to solve.
The lowest common denominator of 2 and 3 is 6, so;
\(x=\frac{3}{6}-\frac{2}{6}\)
Since the denominators are equal, we can now solve the numerators.
\(x=\frac{3-2}{6}\\\\3-2\\\\1\\\\x=\frac{1}{6}\)
Therefore, if \(\frac{1}{2}-\frac{1}{3} = x\), then \(x=\frac{1}{6}\)

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500
Drag each graph to show which transformation was applied to the original figure.
Each graph is the result of one transformation.
On a coordinate plane, a triangle has points (negative 1, negative 1), (negative 4, negative 1), (negative 1, negative 3).
CLEAR CHECK
Translation
Reflection
Rotation
Each graph is the result of one transformation. 1 and 4 are Reflection. 2 , 3, and 5 are rotation and 6 is translation.
How reflection across axis works?When a graph is reflected along an axis, say x-axis, then that leads the graph to go just on the opposite side of the axis as if we're seeing it in a mirror.
Thus, if you're reflecting a point (x,y) along the x-axis, then its x abscissa will stay the same but y ordinates will negate. Thus (x,y) turns to (x, -y)
Similarly, if you're reflecting a point (x,y) along the y axis, the resultant image of the point will be (-x,y)
1st one would be Reflection
2nd would be Rotation
3rd would be Rotation
4th would be Reflection
5th would be Rotation
6th on the bottom would be translation

Step-by-step explanation:
For the first equation,
h-3=9, we need to put all the knowns (numbers) on one side and all the variables on the other side. because equations are like a scale, if we do the same thing to both sides of the equation, the equation will still be true. for this equation, if we add 3 to both sides, we will get:
h-3+3=9+3
this can be simplified to:
h=12
this is your answer.
For the second equation,
we can apply the same principle for the first equation to the second equation.
1/2 x h = 10
can also be written as:
1/2 of h = 10
we can multiply both sides by 2 to get:
1h=20
or
h=20
A worker can load 4 pallets in 30 minutes. At that rate, how many pallets can he load in 4 hours?
Answer:
32
Step-by-step explanation:
1 hour = 60 minutes
Thus, 30 minutes if half an hour.
The worker can load 4 pallets every 30 minutes.
30*2=60
4*2=8
So the worker can load 8 pallets every 60 minutes, or every hour.
8*4=32
So, a worker can load 32 pallets in 4 hours.
BONUS: The worker can load 1 pallet every 7.5 minute

Answer:
30
Step-by-step explanation:
Since 5 and 6 are coprime, the least common multiple is their product, which is 30.
Answer: 30
Step-by-step explanation:
The least common multiple of two numbers, or LCM, is the smallest multiple that can divide evenly into both numbers. We can easily find the LCM by finding the primes that multiply into both numbers.
\(5=5\\ 6=2*3\)
If there were any in common between the factorization of both numbers, we would only need to count it once. Since there weren't any, the smallest multiple of both numbers would be their product, 30.
Hence, the LCM of 5 and 6 is 30.

All you have to do is subtract the equations to get your solution.
1. -18 1/5 - (-2 3/5) = -15 3/5
2. 49.40 - (-85.63) = 135. 03
3. -52.89 - (-25.63) = -78.52
4. -96 2/9 - 24 4/9 = -120 2/3
Note - when there is follow by a subtraction sign and then parentheses such as the examples of 1,2, and 3 you distribute that subtraction sign over. Which will result in positive number.
So, like - (-85.63), distribute the subtraction sign which will result into a positive 85.63.
