Answer:
24.44%
Step-by-step explanation:
1) Find the difference between 45 and 56 as a number.
2) Divide the result from Step 1 by the starting number 45.
3) Multiply the result from Step 2 by 100 to get it in terms of percent.
The three steps above can be made into a formula. Thus, to find the percent change from 45 to 56, we use this formula:
((Y-X)/X)*100 = Percent Change
X is the starting number 45, and Y is the ending number 56 that it changed to. When we enter these numbers into the formula, we get:
((56-45)/45)*100 = 24.44%
Thus, the answer to the question "What is the Percent Change from 45 to 56?" is:

Anamara has 3 cats. She wanst to feed them an equal amount of food. One bag of cat food has 9 grams of food. How many grams will each cats get?
Answer: 3 grams
Step-by-step explanation: Each distribution of food must be equal so divide food by amount of cats which is 3 to get 3
Mathmatically 9/3 = 3 grams
f(x) = 2x² + x – 4
Find f(-10)
NEED IT FAST
Answer:
[tex]f(-10)=186[/tex]
Step-by-step explanation:
We can use substitution to find the value of [tex]f(-10)[/tex].
[tex]f(x) = 2x^2+x-4[/tex]
[tex]f(-10) = 2(-10)^2-10-4[/tex]
[tex]=200-10-4[/tex]
[tex]=186[/tex]
∴ [tex]f(-10) =186[/tex]
Hope this helps :)
Answer:
The value of f(-10) is equal to 186.
Step-by-step explanation:
We are given the function:
[tex]f(x) = 2x^2 + x - 4[/tex]
We are told to find the value of:
[tex]f(-10)[/tex]
If we pay close attention, we can see a transition between:
[tex]f(x) \rightarrow f(-10)[/tex]
We have turned x into -10, making x = -10.
Therefore, we can change the value of x in the entire function to -10.
[tex]f(-10)=2(-10)^2+(-10) - 4\\\\f(-10) = 200 - 10 - 4\\\\f(-10) = 186[/tex]
Therefore, f(-10) = 186.

The equation of your best fit line is
y= 0.404x - 0.003
Use that equation to calculate how high the line will be when
x = 100
Answer:
The answer will be 40.397.
Step-by-step explanation:
Since the equation of your best fit line is y= 0.404x - 0.003 and they want you to calculate how high the line will be when x=100, plug in 100 in x which will be y= 0.404(100) - 0.003 and you'll get an answer of 40.397.
Answer:
40.397
Step-by-step explanation:
0.404(100)-0.003=40.397
Just plug in the X value for X in the equation and solve. it gives you your answer.
Hope this helps.
A bookstore costs $96 a day to keep open, and it spends $12 for each book that it sells. If each book sells for $18, what is the break-even point
for this bookstore?
Answer: The break even point is when they have sold 16 books and have made $288
Step-by-step explanation: The costs are modeled in the equation y = 12x + 96. x is the number of books sold.
The earnings are modeled by he equation y = 18x.
Substitute 18x for y and solve for x.
18x = 12x + 96 Subtract 12x from both sides.
6x = 96 Divide both sides by 6
x = 16
Substitute into the original equations to solve for y
y = 12(16) + 96
y = 192 + 96
Y = 288
y = 18(16)
y = 288
Answer:

Answer:
The system is consistent; it has one solution ⇒ D
Step-by-step explanation:
A consistent system of equations has at least one solution
The consistent independent system has exactly 1 solutionThe consistent dependent system has infinitely many solutionsAn inconsistent system has no solution
In the system of equations ax + by = c and dx + ey = f, if
a = d, b = e, and c = f, then the system is consistent dependent and has infinitely many solutionsa = d, b = e, and c ≠ f, then the system is inconsistent and has no solutiona ≠ d, and/or b ≠ e, and/or c ≠ f, then the system is consistent independent and has exactly one solutionIn the given system of equations
∵ -2y + 2x = 3 ⇒ (1)
∵ -5y + 5x = 12 ⇒ (2)
→ By comparing equations (1) and (2)
∵ -2 ≠ -5
∵ 2 ≠ 5
∵ 3 ≠ 12
→ By using the 3rd rule above
∴ The system is consistent independent and has exactly one solution
∴ The system is consistent; it has one solution
-21, -16, -11, -6, ...
Is this sequence arithmetic, geometric, or neither?
Answer:
Geometric sequence
.Step-by-step explanation:
Geometric sequences are defined by an initial value and a common ratio . If a sequence does not have a common ratio or a common difference, it is neither an arithmetic nor a geometric sequence. You should still try to figure out the pattern and come up with a formula that describes it.
Answer: Neither

Calculate the frequency of light that has a wavelength of
4.25 x 10^-9m and a velocity of 300 m/s.
Answer:
The velocity of light, v, is the product of its wavelength, λ , and its frequency, f. This means that the wavelength is the velocity, v, divided by the frequency, f.
Wavelength of light = velocity of light / frequency of light
λ = v/f
λ = Wavelength of light, meters
v = Velocity of light (c = 3.0 x 108 m, for speed of light if not otherwise defined)
f = frequency of light, Hz

To work this out, we simply need to divide 1 3/4 miles by 4 9/10 miles.
1 3/4 ÷ 4 9/10
Start by converting both terms to improper fractions:
(4/4 + 3/4) ÷ (40/10 + 9/10)
= 7/4 ÷ 49/10
To divide, we simply multiply by the reciprocal of the second fraction:
7/4 * 10/49
= 70 / 196
Now we can take out common factors of the 70 / 196
70 / 196
= (5 * 2 * 7) / (14 * 2 * 7)
= 5 / 14

2. If you use 5 cups of sugar, how much flour do
you need to use?
Answer:
10 flour
Step-by-step explanation:
1:2
5:x all you have to do is multiply by 2, sense the ratio is 1:2, flour will always be 2 times greater than sugar. so the answer is 5 x 2 =10
