the sum of three numbers is 182, the second is 6 times bigger than the first and the third is 14 times bigger than the second number, what are those numbers?
Answer:
The numbers are [tex]2,12,168[/tex]
Step-by-step explanation:
Let the numbers be [tex]a,b,c[/tex]
We have
The sum of three numbers is [tex]182[/tex]
[tex]a+b+c=182-----eqn1[/tex]
The second is [tex]6[/tex] times bigger than the first
[tex]b=6a-----eqn2[/tex]
The third is [tex]14[/tex] times bigger than the second number
[tex]c=14b-------eqn3[/tex]
Substituting in eqn 3
[tex]c=14\times 6a=84a ----eqn4[/tex]
Substituting in eqn 1
[tex]a+6a+84a=182\\\\91a=182\\\\a=2[/tex]
Substituting in eqn 2
[tex]b=6\times2=12[/tex]
Substituting in eqn 3
[tex]c=14\times12=168[/tex]
The numbers are [tex]2,12,168[/tex]
The first number is a , the second number is b , the third number is c
( 0 < a < b < c )
The sum of three numbers is 182
⇒ a + b + c = 182 (1)
The second is 6 times bigger than the first
⇒ b = 6a (2)
The third is 14 times bigger than the second number
⇒ c = 14b = 14.6a = 84a (3)
(1),(2),(3): ⇒ a + 6a + 84a = 182
⇒ 91a = 182
⇒ a = 2
⇒ b = 6a = 6.2 = 12
⇒ c = 14b = 14.12 = 168
Those numbers are 2 , 12 , 168

Isabella made two types of cakes: chocolate and vanilla. She cut all of the
chocolate cakes into 7 slices each and all of the vanilla cakes into 9 slices
each. If Isabella ended up with the same total number of slices of each type
of cake, what is the minimum number of slices of each type?
Answer:
To get the same total number of slices of each type of cake, the answer must be the LCM (lowest common multiple) of 7 and 9.
Multiples of 7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70...
Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90...
As you can see so far, 63 is the lowest common multiple of both 7 and 9.
Thus, the answer is 63
Answer: 63 ( but give the person above me brainliest because they explained it better )
Step-by-step explanation:
If the cakes have the same amount of slices then we must find the lowest common multiple which is 63
So both cakes have 63 slices

If you earned $1000 interest on a loan of $5200 at a yearly interest rate of 2.5%, how many years was the loan for? (Round to the nearest tenth)
Answer:
170 years
Step-by-step explanation:
R/100=2.5%
time= 100=0.025 per year (1/0.025) (5200\1000)-1=168
time=168 years
Answer: 7.7 years
Step-by-step explanation:
Total amount = Principle + Interest = 5200 + 1000 = 6200
A = P(1 + rt)
6200= 5200[1+(0.025)(t)]
6200=5200+130t
-130t=5200-6200
-130t=-1000
t=100/13
t= 7.7 years

Answer:
Simon: 55 hours
Alvin: 70 hours
Theodore: 159 hours
Total: 284 hours
Step-by-step explanation:
Let A, T, and S stand for the hours worked by Alvin, Simon, and Theodore.
We are told that:
A = S + 15,
T = 3S - 6
and
A + S + T = 284
Note that the first two equations state the value of A and T in terms of S. Let's use them in the third equation, so that we'll have only one unknow:
A + S + T = 284
(S + 15) + S + (3S - 6) = 284
5S + 9 = 284
S = 55
Now use this value of S in the first two equations to find A and T:
A = S + 15
A = 55 + 15
A = 70
T = 3S - 6
T = 3*55 - 6
T = 159
(55 + 70 + 159) = 284

Write a function in any form that would match the graph shown below.
Answer:
(x-6)(x+5)^2 - 50
The function that would match the graph shown below is [tex]f(x) = k / (x^2 - 25)[/tex]
where k is a constant.
What is a function?
A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
One example of a function that has intercepts on (5, 0) and (-5, 0) and continues to negative infinity and positive infinity is:
[tex]f(x) = k / (x^2 - 25)[/tex]
where k is a constant that ensures the function continues to negative infinity and positive infinity.
To find the value of k, we can use one of the intercepts, say (5, 0):
0 = k / (5² - 25)
0 = k / 0
This tells us that k can take any value, as long as the denominator is not zero. So, we can choose any non-zero value for k.
For example, let's choose k = 1:
[tex]f(x) = 1 / (x^2 - 25)[/tex]
This function has intercepts on (5, 0) and (-5, 0) and continues to negative infinity and positive infinity.
Thus,
The function that would match the graph shown below is [tex]f(x) = k / (x^2 - 25)[/tex]
where k is a constant.

Based on the cost of the calculator, the discount, the shipping fee, and the tax, the total cost of the purchase was a. $80.07
The cost of the calculator was:
= Cost of calculator x ( 1 - discount)
= 83 x ( 1 - 15%)

When you multiply a number by 25, subtract the result from 2000, and divide everything by 5, you will get 150. What is the initial number?
Answer:
110
Step-by-step explanation:
150*5=750
750+2000=2750
2750/25=110
Answer:
The number is 110
Explanation:
To find the number you have to reverse everything so we will start by the number 150, it says that after dividing by 5 we get 150 so we will multiply 150 with 5 because the opposite of decision is multiplication the answer we get is 750. Then you go a step back again and it says to subtract 2000 and the opposite of subtraction is addition so we add 2000 to 750 and we get 2750. Now we go a step back again and it says to multiply by 25 and the opposite of multiplication is division so we will divide 2750 with 25 and we get 110
Step by step:
150×5= 750
=> 750+2000= 2750
2750÷25= 110
