Answer:
f(-4) is basically just saying that you need to use the function given while x = -4.
The function given:
f(x) = -8(5-x)
We see that f(-4) means that x has to be -4, so we can substitute it in:
f(-4) = -8(5-(-4))
f(-4) = -8(9)
f(-4) = -72
Therefore, f(-4) is -72.

Answer:
Step-by-step explanation:
We can use the formula density mass over volume to find the density of a substance square metal plate has a density of 10.7 g of per cubic centimeters and a mass of 23.54 g calculate the volume
Answer: The volume of given substance is [tex]2.2 cm^{3}[/tex].
Step-by-step explanation:
Given: Density = 10.7 [tex]g/cm^{3}[/tex]
Mass = 23.54 g
Density of a substance is the mass of substance divided by its volume.
Mathematically, [tex]Density = \frac{mass}{volume}[/tex]
Substitute the values into above formula to calculate volume as follows.
[tex]Density = \frac{mass}{volume}\\10.7 g/cm^{3} = \frac{23.54 g}{volume}\\volume = \frac{23.54 g}{10.7 g/cm^{3}}\\= 2.2 cm^{3}[/tex]
Thus, we can conclude that the volume of given substance is [tex]2.2 cm^{3}[/tex].

i really need help to understand this!
Answer:
I believe 90
Step-by-step explanation:
because if you take away 25 (40 pounds) from 100, you divide 100 by 2 to see how many pounds that are 2 $ fit in 100
100/2=50 (pounds)
so 50pounds + the 40pounds (which was the 25$ i took off to make it easier) =90 pounds
hope I helped and feel free to ask questions :)

Two cylinders are similar. The heights of the cylinders are 15 cm and 12 cm. If the surface
area of the smaller cylinder is 487 cm square. find the surface area of the larger cylinder.
Answer:
Step-by-step explanation:
Two cylinders are similar. The heights of the cylinders are 15 cm and 12 cm. If the surface area of the smaller cylinder is 487 cm square. find the surface area of the larger cylinder.
Height of the smaller cylinder = 12cm
Area of the smaller cylinder = x
Height is the bigger cylinder = 15cm
Area of the bigger cylinder = 487cm²
We can find the radius of the bigger cylinder
Radius of the bigger cylinder = 4.07 cm
Hence: we form our proportion to find radius of Smaller cylinder
12/15 = x/4.07
Cross Multiply
15x = 12 × 4.07
x = 12 × 4.07/15
x = 3.256 cm

Step-by-step explanation:
Which of the following proportional relationships has a higher rate
Answer:
the proportional relationship represented by the table has a higher rate of change (15)
Step-by-step explanation:
✔️The rate of y = 12x is 12
✔️Rate of the table of values given is:
y/x = 30/2 = 60/4 = 75/5 = 15
Rate of change for the table of values = 15
✔️Rate of change for the graph given can be found using the coordinates of any point on the line:
Using (1, 4),
rate of change = y/x = 4/1 = 4
✅Therefore we can conclude that the proportional relationship represented by the table has a higher rate of change (15)

Help plz math question. EXPLAIN HOW YOU GOT THE ANSWER. 30 PTS btw thx if u help
Answer:
256
Step-by-step explanation:
4^4^4 = 4^(4^4) = 4^256
so written in base 4, there will be 256 zeroes after a 1.
This translates to approximately 154 digits in decimal.
Just like 2^2^2 = 2^4
there will be four zeroes after a 1.
2^2^2=2^(2^2) = 2^4 = 16 = 10000 (16 in base 2).
2.5x + 1 = 26 help hurryyyyyyyyy!!!!?!?!??!?!?!
Answer:
2.5x=26-1
x=25/2.5
x=10
Step-by-step explanation:
Answer:
I assume you're solving for x, so the answer is 10
Step-by-step explanation:
First you isolate the x, so you need to subtract one from both sides, which results in the equation 2.5x = 25, and then you divide 25 by 2.5, which gives you x = 10

Ruby is ordering some pizza! She has to pay for the cost of the pizza plus the cost of the delivery fee(cost per minute that it takes a the delivery driver to get to her house). The pizza cost $12, and it took 10 minutes for the delivery driver to get there. In total, she has to pay $15
Answer:
Delivery cost per minute = $0.3 per minute
Step-by-step explanation:
Given:
Cost of pizza = $12
Total amount pay by Ruby = $15
Time taken for delivery = 10 minutes
Find:
Delivery cost per minute
Computation:
Total amount of delivery = Total amount pay by Ruby - Cost of pizza
Total amount of delivery = 15 - 12
Total amount of delivery = $3
Delivery cost per minute = Total amount of delivery / Time taken for delivery
Delivery cost per minute = 3 / 10
Delivery cost per minute = $0.3 per minute

PLEASEEEE HELPPPPP PLEASEEEE
Answer/Step-by-step explanation:
A. The quadrilateral cam be named using the letters of the vertices. Thus, it is named as: quadrilateral LMNP
B. 82° + (3x - 1)° = 180° (adjacent angles are supplementary)
Solve for x
82 + 3x - 1 = 180
Add like terms
81 + 3x = 180
Subtract 81 from both sides
3x = 180 - 81
3x = 99
x = 99/3
x = 33
C. Opposite angles in a quadrilateral are equal. Therefore,
m<L = (3x - 1)°
Plug in the value of x
m<L = 3(33) - 1
m<L = 99 - 1
m<L = 98°

3. You owe $1,350.00 on a credit card with a 14.25% APR. You pay $300.00 at the beginning of
the month How much interest do you save by paying at the beginning of the month versus
at the end of the month?
Answer:
Step-by-step explanation:
As an aside, I don't know why Americans don't use a debit card. Usually to figure out what the monthly interest is, you divide the yearly interest by 12
14.25 / 12 = 1.875 and you keep all the decimals.
1350 * 1.875 / 100 = 16.03 is what you save, but there is more. It seems very tiny, but don't be fooled. The credit card company certainly isn't. They will likely round up to 16.04 just so hackers won't make anything if they break into someone's account.
16.04 doesn't seem like much to pay, but realize that if you had to pay it every month, it would be 192.48 a year. That on 1350 is usury.
