Step-by-step explanation:
The proportion of the money that Sarah gets is 2/3 of the total amount
How to determine Sarah's proportion?From the complete question, the fraction of the money is:
Caroline = 1/9
The remaining amount is calculated using:
Remaining = 1 - 1/9
Evaluate
Remaining = 8/9
Colin and Sarah's share is:
Colin : Sarah = 1 : 3
This means that Sarah's share is:
Sarah = 3/(3 + 1) * 8/9
This gives
Sarah = 3/4 * 8/9
Evaluate
Sarah = 2/3
Hence, the proportion gotten by Sarah is 2/3

ALGEBRAICALLY solve each system of equations below. Show all of your work!
a. 7x - y = 98
3x-5y=10
b. x + 3y = 4
x = 6 - 27
Answer:
a. y = 7x-98
y =-3/5x-2
b. y =-1/3x+4/3
x =-21
Step-by-step explanation:
a. 7x - y = 98
98 - 7x
-y = -7x + 98
divide by -
y = 7x - 98
3x - 5y = 10
10 - 3x
-5y = -3x + 10
divide by -5
y = -3/5x - 2
b. x + 3y = 4
4 - x
3y = -1x + 4
divide by 3
y = -1/3x + 4/3
x = 6- 27
x = -21
convert 0.16 liters to milliliters
0.16 liters in terms of mililiters is equal to 160 ml
What is the unitary method?The unitary method is a method in which you find the value of a unit and then the value of a required number of units.
Given here: 0.16 liters
Now we know 1 liter= 1000 ml
Thus 0.16 liter would be equal to 0.16×1000=160 ml
Hence, 0.16 liters in terms of mililiters is equal to 160 ml

Step-by-step explanation:
This question is asking you to insert two equations, f(x) and g(x), into the equation g(x) - f(x). This will lead to the equation below.
[tex] { - 12x}^{2} - 15x + 7 - ({ - 7)x}^{2} + 9x - 15[/tex]
Now we can solve for the equation.

Calculate the average rate of change of f (x) = 3x2 + 2x + 5 on the interval (0, 2).
A. -1
B. 8
C. 38
D. 128
The average rate of change of a continuous function f(x) in an interval (a, b) is
(f(b) - f(a)) / (b - a)
So for
f(x) = 3x ² + 2x + 5
on the interval (0, 2), we have
• f (2) = 3 • 2² + 2 • 2 + 5 = 21
• f (0) = = 3 • 0² + 2 • 0 + 5 = 5
so that the average rate of change is
(f (2) - f (0)) / (2 - 0) = (21 - 5) / 2 = 16 / 2 = 8
and the answer is B.
The students at Porterville Elementary sold raffle tickets, each for the same price, for a fundraiser. The equation below shows how much money was raised with t tickets sold. $836 = $11t What is the unit rate in the equation above?
Answer:
76
Step-by-step explanation:
We were given The equation below which shows how much money was raised with t tickets sold. $836 = $11t
Mathematically, unit rate is How much of something per 1 unit of something else
$836 = $11t
Then we can get the value for "t" as
t= 836/11
t= 76
Hence, Unit rate is 76

Given f(x)=x^3+kx-2, an x−1 is a factor of f(x), then what is the value of k?
Answer:
The value of k is 1
Step-by-step explanation:
If x-1 is a factor, if we equate x - 1 to 0 and substitute the value of x
Then, we should have 0 as the f(x) value
so;
x-1= 0
x = 1
Substitute this
0 = 1^3 + k(1) - 2
0 = 1 + k-2
0 = k-1
k = 1

Need help with this please
Answer:
55 degrees.
Step-by-step explanation:
ok so first off we know altogether the angles of a triangle have to equal 180 degrees total we have one thats 80 so the other two together must be 100 given that information we can make the equation 7x+6+3+6x=100 we simplify to get 13x+9=100 after moving it around you get 13x=91 solve the equation by dividing both sides by 13 to get x=7, but we are not done we have to solve for angle A by inputting the X so we get angle A=55 degrees
====================================================
Work Shown:
A+B+C = 180 ..... angles of a triangle add to 180
(7x+6) + (80) + (3+6x) = 180
13x + 89 = 180
13x = 180-89 .... subtract 89 from both sides
13x = 91
x = 91/13 .... divide both sides by 13
x = 7
Use this x value to find the missing angle measures.
angle A = 7x+6 = 7*7+6 = 55
angle C = 3+6x = 3+6*7 = 45
Note that,
A+B+C = 55+80+45 = 180
which helps confirm our answer.

JJ decides to leave a tip that is 15% of the original price for his meal. How much should he leave as tip for the $5.50 cheeseburger and $2.50 milkshake? Express your answer to the hundredths place?
Answer: $9.20
Step-by-step explanation: To get the answer, you add both the cost and multiply it by .15. Then you add the product to the number you got adding the cost of the food.
Answer:
$1.20
Step-by-step explanation:
He has to leave 100% of the cost which is $5.50 + 2.50 or $8.00.
He wants to leave 115% of the $8 he has to leave.
So you set it up like
x/8 = 115/100
Then you solve for x
8(115) = 920
920/100 =9.2
So he will leave $9.20.
It then asks for just how much the tip is that he will leave so
9.2 - 8 = 1.2
So the tip is $1.20.
