Answer:
c(10) is 25 which means there is a balance of $25 in cafe account after 10 days
Step-by-step explanation:
c(10) = 50 - 2.5(10)
c(10) = 50 - 25 which is 25
Based on the pattern shown, what is 46?
41 = 4
42 = 16
43 - 64
Answer: 44 equals 128
Step-by-step explanation: This is because you do 16 times 4 to get 64, then you double that to 8, so you do 16 times 8 and get your answer 128

12 and a half percent of 48.40
Answer:
6.05
Step-by-step explanation:
12 and a half percent of 48.4 = 6.05 because you can put .125 in your calculator and it is the same at 12.5% so you do .125 * 48.40 and you get 6.05

Amanda was 48 inches tall. She grew n inches last year and is now 56.5 inches. Which expression represents the number of inches Amanda grew?
56.5 + n = 48
48 + n = 56.5
48 - n = 56.5
48n = 56.5
Answer:
It should be 48+n=56.5
Step-by-step explanation:
Answer: Choice B
48 + n = 56.5
============================================================
Work Shown:
48 = height last year, in inches
n = number of inches she grew last year
48+n = current height right now, in inches
48+n = 56.5 since her current height is 56.5 inches
Side notes:
48 inches = 4 feet56.5 inches = 4.71 feet (approximate) = 4 ft, 8.5 inches (exact)To convert from inches to feet, you divide by 12. The equation in bold solves to n = 8.5, meaning she grew 8.5 inches over the last year.Find the value of k, such that x² - 4x2 + kx + 4 will leave a remainder of 4 when divided by (x - 1).
A -3
B 8.4
C 0,3
D -4
Can someone help me with this one ASAP
Answer:
k=4
Explanation:f(x)=x3+4x2−kx+1By the remainder theorem, the remainder when dividing a polynomial f(x)by (x−a)
is f(a)In our case, we have a=−1 and we need:0=f(−1)=(−1)3+4(−1)2−k(−1)+10=f(−1)=−1+4+k+10=f(−1)=k+4
Hence k=−4
might have gotten it wrong sorry if so.
You want to open a checking account at your local bank which offers two options. A standard checking account charges $6 each month plus $.25 for each check written. A select checking account charges $4.50 each month plus $.50 for each check written. Which system of equations can be used to determine the number x of checks that must be written in a month in order for the total charges y for the two checking accounts to be the same?
Answer:
The total charges for the two checking accounts will be the same after 6 checks written.
Step-by-step explanation:
Since I want to open a checking account at my local bank which offers two options, a standard checking account that charges $ 6 each month plus $ 0.25 for each check written, and a select checking account that charges $ 4.50 each month plus $ 0.50 for each check written, to determine which system of equations can be used to determine the number X of checks that must be written in a month in order for the total charges Y for the two checking accounts to be the same, the following calculation must be performed:
6 + 0.25X = Y
4.5 + 0.5X = Y
6 + 0.25x5 = Y
4.5 + 0.5x5 = Y
6 + 1.25 = Y = 7.25
4.5 + 2.50 = 7
6 + 0.25x6 = Y
4.5 + 0.5x6 = Y
6 + 1.50 = Y = 7.50
4.5 + 3 = 7.50
Therefore, the total charges for the two checking accounts will be the same after 6 checks written.

A train trip took 4 hours. For the trip, the train traveled at 60 kilometers per hour. For the
2
rest of the trip, the train traveled at 100 kilometers per hour. How far did the train travel
in all?
Answer:
320 kilometers
Step-by-step explanation:
1/2 -- (60 * 2) = 120 km
rest pf the trip -- 100 km per hour -- 2 hours left -- (100 * 2) = 200 km
Therefore, 120 + 200 = 320 km
Thenks and mark me brainliest :)
Let A be the set of all lines in the plane. Define a relation R on A as follows. For every l1 and l2 in A, l1 R l2 ⇔ l1 is parallel to l2. (Assume that a line is parallel to itself). Which of the following is true for R?
A. R is reflexive.
B. R is symmetric.
C. R is transitive.
D. R is neither reflexive, symmetric, nor transitive.
Answer:
Hence, the relation R is a reflexive, symmetric and transitive relation.
Given :
A be the set of all lines in the plane and R is a relation on set A.
[tex]R=\{l_1,l_2\in A|l_1 \;\text{is parallel to}\; l_2\}[/tex]
To find :
Which type of relation R on set A.
Explanation :
A relation R on a set A is called reflexive relation if every [tex]a\in A[/tex] then [tex](a,a)\in R[/tex].
So, the relation R is a reflexive relation because a line always parallels to itself.
A relation R on a set A is called Symmetric relation if [tex](a,b)\in R[/tex] then [tex](b,a)\in R[/tex] for all [tex]a,b\in A[/tex].
So, the relation R is a symmetric relation because if a line [tex]l_1[/tex] is parallel to the line [tex]l_2[/tex] the always the line [tex]l_2[/tex] is parallel to the line [tex]l_1[/tex].
A relation R on a set A is called transitive relation if [tex](a,b)\in R[/tex] and [tex](b,c)\in R[/tex] then [tex](a,c)\in R[/tex] for all [tex]a,b,c\in A[/tex].
So, the relation R is a transitive relation because if a line [tex]l_1[/tex] s parallel to the line [tex]l_2[/tex] and the line [tex]l_2[/tex] is parallel to the line [tex]l_3[/tex] then the always line [tex]l_1[/tex] is parallel to the line [tex]l_3[/tex].
Therefore the relation R is a reflexive, symmetric and transitive relation.
Circle O and circle P are congruent. What can you conclude from the diagram?
Answer:
We can only infer that OA=OB=PD=DE.
Step-by-step explanation:
Since, if two circles are congruent then their radius must be equal.
And, here A and B are the points in the circumference of circle O therefore, the distance of these points from the center O of the circle is the radius of the circle.
So, OA=OB. ( if we join the points O and C then OA=OB=OC)
Similarly, In Circle P, PE= PD. ( if we join the points P and CF then PD=PE=PF).

Dan has put his coins into 2 stacks, Each stack has the same number of coins. There are 12 coins total, How many coins are in each stack?
Answer: 6
Step-by-step explanation: Division use a calculator 12/2
Answer:
6
Step-by-step explanation:
From question:
Dan has put his coins into 2 stacks
2 stacks in total
Each stack has the same number of coins
Number of coins in stack 1 = number of coins in stack 2
x = x
There are 12 coins total
Total number of coins in 2 stacks = 12
2x = 12
x = 6
There are six coins in one stack.

Find missing side round to nearest tenth
Answer:
x = 9.9 or 10
Step-by-step explanation:
to find missing angle -->
90 + 61 + z = 180
151 + z = 180 *subtract 151 from both sides*
z = 29
to find x -->
tan (29) = x/18 *put tan(29) over 1 then cross multiply*
x = 18 (tan(29))
x = 9.97 --> round up to 10

Answer:
Circumference of given circle = 154 cm² (Approx.)
Step-by-step explanation:
In given diagram:
Diameter of given radius = 49 cm
Value of π = 3.14
Find:
Circumference of given circle
Computation:
Radius of given circle = Diameter of given radius / 2
Radius of given circle = 49 / 2
Circumference of given circle = 2πr
Circumference of given circle = 2(3.14)(49/2)
Circumference of given circle = (6.28)(49/2)
Circumference of given circle = 153.86
Circumference of given circle = 154 cm² (Approx.)
