Scott had a balance of $1910.30 in his bank account on August 1st. On August 12th, he wrote a check to the local car shop for $75.00, then on August 21st his friend gave him a check for deposit $41.50. Then he bought groceries for 210.25. How much money does she have in her bank account?
Answer: $1,666.55
Step-by-step explanation:
The amount of money that Scott will have in the bank will be the total of the money that was in the bank at the beginning of August plus any money received, less any money that was disbursed.
= Beginning balance + check from friend - check to local car shop - cash spent on groceries
= 1,910.30 + 41.50 - 75.00 - 210.25
= $1,666.55
Figure is assuming groceries were paid for by cash from bank account.

A bag has three marbles: one red, one blue, and one yellow. The marbles are pulled from the bag one at a time without replacing them. In how many different orders could the marbles be pulled from the bag?
The number of different orders that the marbles can be pulled from the bag is 6 ways
Combination and permutation of numbersIf a bag contains one red, one blue, and one yellow, then the total number of marbles contained is 3 marbles.
If the marbles are pulled from the bag one at a time without replacing them, the number of different orders that the marbles can be pulled from the bag is expressed as:
[tex]3C_1=\frac{3!}{(3-2)!} \\3C_1=\frac{3!}{1!}\\ 3C1=3! = 6ways[/tex]
Hence the number of different orders that the marbles can be pulled from the bag is 6 ways

A triangle has a base of 14 centimeters and a height of ( 3x - 4 ) centimeters . The area of the triangle is greater than 56 centimeters . Solve the inequality 1/2 (14) ( 3x - 4 ) > 56 to find the possible values of x???
show your work please
Answer:
1/2 (14) ( 3x - 4 ) > 56
14/2 (3x-4) > 56
7 (3x-4) > 56
21x - 28 > 56
21x > 56+28
21x > 84
x < 4
Answer:
x > 4 or x = (4, + oo)Step-by-step explanation:
The area of the triangle is
A = 1/2bhGiven
b = 14 cmh = 3x - 4Then
A = 1/2*14(3x - 4) = 7(3x - 4) = 21x - 28If A > 56, then solving inequation:
21x - 28 > 5621x > 56 + 2821x > 84x > 84/21x > 4 or x = (4, + oo)find f(-1)+g(2)
f(x)=5x-20
g(x)=x^2+5x-11
Step-by-step explanation:
f(x) = 5x - 20
f(-1) = 5(-1) - 20 = - 5 - 20
= - 25
g(x) = x² + 5x - 11
g(2) = 2² + 5(2) - 11 = 4 + 10 - 11
= 3
Thus, f(-1) + g(2) = - 25 + 3 = - 22
Answer:
Step-by-step explanation:
Substituting x as -1 in f(x), f(-1)
F(-1)=5(-1)-20
F(-1)=-5-20
F(-1)=-25
Substituting x as2 into g(x), g(2)
G(x) =2^2+5(2)-11
G(x)=4+10-11
G(x)=3
F(-1)+g(2)=-25+3

A castle has to be guarded 24 hours a day. 7 knights are ordered to split each day's guard duty equally. How long will each knight spend on duty? Record your answer in minutes
Answer:
≈206 Minutes
Step-by-step explanation:
We know that the castle has to be guarded for 24 hours a day. Since there are 60 minutes in an hour, that means it must be guarded for 1,440 minutes (60 * 24 = 1,440). If we split this evenly between each of the 7 knights, through division, we know that they must each be on guard for 205.714285714 minutes, or approximately 206 minutes.

Justin has 64 ounces of lemonade to divide among 9 people. When he types 64÷9 into his calculator, the number that appears is 7.111111111. How much lemonade should he give to each person?
The number of lemonade should Justin give to each person is 7 with one lemonade still left.
It is given that Justin has 64 ounces of lemonade to divide among 9 people.
We have to find out that how much lemonade should he give to each person.
What will be the value of each part , if 120 is divided in 6 equal parts ?
The value of each part will be 120 divided by 6 or 120 ÷ 6 or 20 i.e., 120 is divided into 6 equal parts of 20 each.
As per the question ,
No. of ounces of lemonade to divide among 9 people = 64
No. of lemonade each people will get = 64 ÷ 9
or
64 ÷ 9 = 7.1111
So , we can't equally divide it because if 7 each is divided between 9 people , one lemonade will still be left.
i.e.,
7 × 9 = 63
64 - 63 = 1
1 still left
Thus , the number of lemonade should Justin give to each person is 7 with one lemonade still left.

Cesar is excited that he only has 12 months left before he pays off his credit card completely. His current balance is $3,750 and his APR is 17. 5%. But when he is involved in a car accident, he is forced to use his credit card to pay a $1,000 deductible to get his car fixed. How much will Cesar’s minimum monthly payment increase if he still wants to pay off his credit card in 12 months? a. $83. 33 b. $91. 44 c. $342. 91 d. $434. 35.
The amount by Cesar’s minimum monthly payment increase will be $91.44.
What will be the amount?Cesar only has 12 months left before he pays off his credit card completely.
His current balance = $3,750
APR = 17.5%
Now we use the formula :
[tex]\rm Present \ value \ of \ anuity= P=( 1-\frac{1+r}{r} })^{-n}[/tex]
PV = Present Value
P = Periodic payment
r = rate per period
n = number of period
Now for the first case:
PV of annuity = $3,750
P =?
r = 17.5% annually = % monthly monthly
n = 12 months
Now we put the values in the formula
[tex]3750=P(1-\dfrac{(1+\dfrac{17.5}{1200})^{-12}}{\dfrac{17.5}{1200} } )[/tex]
[tex]P=\dfrac{3750}{\dfrac{1-0.8405}{0.01458} }[/tex]
[tex]P=342.91[/tex]
Now for the second Case :
PV of annuity = 3750 + 1000 = 4750
P =?
r = 17.5% annually = % monthly = monthly
n = 12 months
Putting the values in the formula
[tex]4750=P(1-\dfrac{(1+\dfrac{17.5}{1200})^{-12}}{\dfrac{17.5}{1200} } )[/tex]
[tex]P=\dfrac{4750}{1-\dfrac{1+\frac{17.5}{1200} }{\frac{17.5}{1200} } }[/tex]
[tex]P=\dfrac{4750}{\dfrac{0.1595}{0.01458} } =434.35[/tex]
Cesar's increased monthly payment will be
434.35 - 342.91 = 91.44
Hence, the amount by Cesar’s minimum monthly payment increase will be $91.44.

Answer: a. 14 Computers
b. 62 Computers
Step-by-step explanation:
a) What is the amount of increase in computers needed?
Number of Computers sold last month = 48
Percentage increase required = 30%
Amount of increase in computers needed= 30% × 48
= 0.3 × 48
= 14.4
= 14 approximately
b)What is the new amount of computers the team must sell?
This will be the amount of Computers sold last month plus the increase.

where r= the radius, and h= the height of the cone. Determine the amount of liquid a paper cone can hold with a 3-inch diameter and a 5-inch height
Answer:
11.78 in³
Step-by-step explanation:
The formula for the volume of a cone is ...
V = 1/3(πr²h)
The cone's radius is half its diameter, so is 1.5 inches. The volume is ...
V = 1/3π(1.5 in)²(5 in) = 3.75π in³ ≈ 11.78 in³
The cone can hold about 11.78 cubic inches of liquid.
