Emma wants to paint her house light pink. She adds 6 cans of white paint to every 4 cans of pink
paint to make the desired color. How many cans of white paint will she need to mixed with 12 cans of
pink?
To find out how many cans of white paint Emma will need to mix with 12 cans of pink paint, we can use the proportion of white paint to pink paint that she is currently using: 6 cans of white paint to every 4 cans of pink paint.
We can set up an equation using the proportion:
white paint/pink paint = 6/4 =3/2
We know that Emma wants to use 12 cans of pink paint, so we can use this information to solve for the number of cans of white paint she needs:
white paint/pink paint = 3/2
white paint = (3/2) * pink paint
white paint = (3/2) * 12 cans
white paint = 18 cans
So Emma will need 18 cans of white paint to mix with 12 cans of pink paint to get the desired color.

Question 19
Luke invests 34000 into an account that pays 3. 4% compound interest per annum for the first two years, and 2. 3%
thereafter.
Given that the interest is paid into his account monthly (and calculated monthly), work out how much money Luke
will have in his account after 6 years and 3 months.
As per the formula of compound interest the amount in his account after 6 year 3 months is $40,085.307
In math the term called compound interest is defined as when you earn interest on both the money you've saved and the interest you earn.
Here we know that Luke invests 34000 into an account that pays 3. 4% compound interest per annum for the first two years and 2. 3% thereafter.
Here we need to find the amount in his account after 6 years and 3 months.
Then it can be calculated as,
FV = PV(1 + i)ⁿ
Here we know that PV = 34000 and i = 3.4% for two years,
Then the FV is value is calculated as,
=> FV = 34000(1 + 3.4/100)²
=> FV = 34000 ( 1 + 0.034)²
=> FV = 36351.304
Similarly, the FV value of 4 years 3 months is calculated as,
=> FV = 36351.304(1 + 2.3/100)⁴°³
=> FV = 36351.304(1 + 0.023)⁴°³
=> FV = 40085.307

Mr.Todd want to paint the outide of the birdhoue. How much paint doe he need to buy to cover the outide of the entire birdhoue( rounded to the nearet hundredth). Explain how much and how you know in at leat two entence.
The amount of paint needed is 176/36000 = 0.0049 gallons, which is equivalent to 4.9 milliliters, rounded to the nearest hundredth.
To calculate how much paint Mr.Todd needs to buy to cover the outside of the entire birdhouse, we must first know the dimensions of the birdhouse. Let's assume the birdhouse has the dimensions of 10 inches long, 8 inches wide and 6 inches tall, and each side requires 1 coat of paint. The total surface area of the birdhouse is then 10 x 8 + 10 x 6 + 8 x 6 = 176 inches squared. Next, we need to know the coverage of the paint, which we will assume is 250 square feet per gallon. Since 1 square foot is equal to 144 square inches, the coverage of the paint is 36000 square inches per gallon. To find out how many gallons of paint are needed to cover the birdhouse, we need to divide the total surface area of the birdhouse (176 square inches) by the coverage of the paint (36000 square inches per gallon). Therefore, the amount of paint needed is 176/36000 = 0.0049 gallons, which is equivalent to 4.9 milliliters, rounded to the nearest hundredth.

How to find the energy of the object?Energy is the ability to do work. It can take many forms, such as kinetic energy (energy of motion), potential energy (stored energy) etc.
If a 15-kg child is tossed up into the air by her parent and the child is 2.5 meters off the ground traveling 3 m/s.
Then boy has kinetic energy due to his motion and also has potential energy due to his height.
Thus, M = 15-kg, h = 2.5 meters and V = 3 m/s
KE = 1/2(M)(V)² = 1/2 × 15 × 3² = 67.5 J

The second company offered him a weekly salary of $ 350.00 $350.00 plus a commission of $ 1.30 $1.30 for each cupcake he sells. How many cupcakes must John sell each week for the total pay from each company to be the same?
PLEASE ANSWER FAST WORTH 92 POINTS
Answer:
450 cupcakes
Step-by-step explanation:
Let x be the number of cupcakes sold for John's total pay to be the same for both companies
For the first company
Salary = $800/week
Commission is $0.30 per cupcake
For sales of x cupcakes, total commission = 0.30x
Total pay = Weekly salary + Total commission from sales
Total Pay = 800+ 0.3x
For the second company
Salary = 350 /week
Commission: $1.30 per cupcake
For sales of x cupcakes, total commission = 1.30x
Total Pay = Weekly salary + Total commission from sales
Total Pay = 350 + 1.3x
If both pay must be he same,
800 + 0.3x = 350 + 1.3x
800-350 = 1.3x - 0.3x
450 = 1x
x = 450 cupcakes ANSWER
Answer: 450
Step-by-step explanation:
If we let x and y represent the number of cupcakes John sells and his total weekly income, respectively, we get the following system of equations.
=0.35x+845
=1.4x+372.5
Since both equations are solved for y, any substitution for y will result in the following
211.4 x+372.5&=0.35
x+845
1.4x+372.5
=0.35x+845
Solving for x will give us the number of cupcakes John needs to sell weekly for each paycheck to be the same. Doing so, we get
1.4 x+372.5&=0.35 x+845
1.05 x&=472.5x=450
1.4x+372.5
1.05x
x
=0.35x+845
=472.5
=450
Therefore, John needs to sell 450450 cupcakes each week for both salaries to be the same.

For example, at time t = 10 min, the amount of salt in the tank is 200 - 140e^(-10/25) = 200 - 140(0.7787) = 124.42 oz.
This calculation assumes that brine containing oz of salt per gallon of brine is allowed to enter the tank at a rate of gal/min and the mixed solution is drained from the tank at the same rate. Thus, the amount of salt in the tank is decreasing exponentially with time.

3. If f(x) = x² - 2x + 7, evaluate the following:
f(-5)
f (0)
ƒ (1)
The minimum value of Y is -6 and the maximum value is 10. The range is {-6, 1, 2, 3, 10}.
What is the domain and how is the range calculated range ?Domain of Y = -x³ + 2: A = {-2, -1, 0, 1, 2}. The equation is defined for all x in the set A.
Range of Y = -x³ + 2: To find the range, we need to find the minimum and maximum values of Y for x in the set A. Using the formula Y = -x³ + 2, we can substitute the values of x from the set A and find the corresponding values of Y:
x = -2, Y = -(-8) + 2 = 10
x = -1, Y = -(-1) + 2 = 3
x = 0, Y = -(0) + 2 = 2
x = 1, Y = -(1) + 2 = 1
x = 2, Y = -(8) + 2 = -6
Thus, the minimum value of Y is -6 and the maximum value is 10. The range is {-6, 1, 2, 3, 10}.
Relation Y = -x³ + 2 is a function: A relation is a function if every input x in the domain corresponds to only one output Y in the range. To check if the relation is a function, we need to ensure that no two different inputs in the domain result in the same output.
For this relation, every input x in the domain results in only one unique output Y, so the relation is a function.
Function Notation: If the relation is a function, we can write it in function notation as: f(x) = -x³ + 2, where f is the function name and x is the input.
Evaluating f(-5), f(0) and f(1):
f(-5) = -(-125) + 2 = 127
f(0) = -(0) + 2 = 2
f(1) = -(1) + 2 = 1
Thus, f(-5) = 127, f(0) = 2 and f(1) = 1.

2. Mark is trying to fit a circular tabletop with a diameter
of 88 inches through a door. The width of the door is 36
inches and the height of the door is 84 inches. Will the
tabletop fit through the door?
Answer: lol no it won't
Step-by-step explanation:
In order to determine if the circular tabletop with a diameter of 88 inches will fit through the door, we must compare the dimensions of the tabletop to the dimensions of the door.
The width of the door is 36 inches and the height of the door is 84 inches. The diameter of the tabletop is 88 inches. To fit through the door, the tabletop's diameter must be less than or equal to both the width and the height of the door.
88 inches > 36 inches and 88 inches > 84 inches
In this case, the tabletop will not fit through the door because its diameter is larger than both the width and the height of the door.
