Mrs.stevens has award winning rose bushes that grow at a rate of 3/4 foot per week. Her American home rose bush currently measures 5 feet tall, while her camp David Rose bush is 4 1/2 feet tall in two weeks how tall will mrs.stevens American home rose bush measure?
Answer:
The answer would be 6.5 feet.
Pre-Thinking:
Knowing that the rose bushes grow at a rate of 3/4 feet per week, we can turn that into 0.75, a decimal.
Because, we need to know the height of the rose bush in 2 weeks, multiply 0.75 by 2.
0.75 * 2 = 1.5
Working and Stuff:
Because we only need the length of the American Home Rose Bush, which is 5 feet tall, we can discard the other rose bush.
Lastly, add 1.5 to 5.
1.5 + 5 = 6.5 feet

Which equation is equivalent to 2x + 6y = 12?
Answer:
Option C, y = -1/3x + 2
Step-by-step explanation:
2x + 6y = 12
Step 1: Solve for y
2x + 6y - 2x = 12 - 2x
6y / 6 = (12 - 2x) / 6
y = 2 - 1/3x
Answer: Option C, y = -1/3x + 2
Answer:
y = (1/3)x + 2
Step-by-step explanation:
2x + 6y = 12 can be reduced by dividing all three terms by 2; we get:
1x + 3y = 6.
We solve for y. First, subtract 1x from both sides, obtaining:
3y = -1x + 6.
Next, divide all three terms by 3. We get
y = (1/3)x + 2

A candy store makes a 10-lb mixture of gummy worms, candy corn, and sourballs. The cost of gummy worms is $1.00 per pound, candy corn cost $3.00 per pound, and sourballs cost $1.50 per pound. The mixture calls for three times as many gummy worms as candy corn. The total cost of the mixture is $15.00. How much of each ingredient did the store use?
Answer:
6 grams of gummy worms, 2 grams of candy corn and 2 grams of sourballs.
Step-by-step explanation:
Let the number of pounds of each ingredient be as follows:
Gummy Worms = x pounds
Candy Corn = y pounds
Sourballs = z pounds
The store makes a mixtures of 10 pounds. This means the sum of x, y and z would be 10. Setting up the equation:
[tex]x + y +z = 10[/tex] (Equation 1)
The mixture calls for 3 times as many gummy worms as candy corn. This means amount of gummy worm will be 3 times the candy corn. Setting up the Equation:
[tex]x=3y[/tex] (Equation 2)
Cost of gummy worms is $1.00 per pound, candy corn cost $3.00 per pound, and sourballs cost $1.50 per pound. So cost of x, y and z pounds would be:
1x , 3y and 1.5z, respectively. The total cost of mixture is $15. So we can set up the Equation as:
[tex]x+3y+1.5z=15[/tex] (Equation 3)
Using the value of x from Equation 2, in Equations 1 and 3 give us following two equations:
[tex]4y+z=10[/tex] By substitution in Equation 1. (Equation 4)[tex]6y+1.5z=15[/tex] By substitution in Equation 3. (Equation 5)
Multiplying the Equation 4 by 1.5 and subtracting from Equation 5 gives us:
[tex]6y +1.5z-1.5(4y+z)=15-1.5(10)\\\\ 6y+1.5z-6y-1.5z=15-15\\\\ 0=0[/tex]
When two sides of equations turn into something that is always positive, we conclude that there are infinite number of solutions. In such cases, we fix a variable and give different values to it, to find corresponding values of other variables. Lets re-write the solution in terms of z.
From Equation 4, we have:
[tex]y=\frac{10-z}{4}[/tex]
From Equation 2, we have:
[tex]x=3(\frac{10-z}{4} )[/tex]
Therefore, the solution set will be:
[tex](3(\frac{10-z}{4} ), \frac{10-z}{4} , z)[/tex]
Now in order to find any combination of ingredient, we give any value to z. Let, z is equal to 2 grams.
So,
x would be = 6 grams
y would be = 2 grams
So, one of the possible amount of ingredients that store can use is:
6 grams of gummy worms, 2 grams of candy corn and 2 grams of sourballs.

The value of a car is $30,000. It loses 6.5% of its value each year. What will the value of the car be after 5 years?
The value of a car that costs $30,000 and depreciates at 6.5% annually will be $22,530 after 5 years, calculated using exponential decay.
The value of a car is $30,000 and it loses 6.5% of its value each year. To calculate the value of the car after 5 years, we can apply the concept of exponential decay. The value after one year would be the initial value minus 6.5% of the initial value. Mathematically, we can express this as:
V1 = V0 (1 - 0.065),
where V1 is the value after one year and V0 is the initial value. To find the value after 5 years, we would apply this formula iteratively or use the formula for exponential decay:
Vn = V0 x (1 - 0.065)ⁿ,
where Vn is the value after n years. Therefore:
V5 = $30,000 x (1 - 0.065)⁵,
V5 = $30,000 x (0.935)⁵,
V5 = $30,000 x 0.7510,
V5 = $22,530.
After 5 years, the value of the car will be $22,530.
A recipe calls for 2/5 of a pound of chicken for each person. If there are 8 people to be fed how many pounds of chicken are required?
Answer:
3 1/5
Step-by-step explanation:
The 2 pounds of chicken are required to feed 8 people.
To find out how many pounds of chicken are required to feed 8 people, we can multiply the amount of chicken required per person by the number of people:
2/5 pound of chicken per person * 8 people = 2 pounds of chicken
Therefore, 2 pounds of chicken are required to feed 8 people.
Another way to solve this problem is to use ratios. We know that we need to feed 8 people and that we have 2/5 of a pound of chicken per person. We can set up a ratio to find out how many pounds of chicken we need:
8 people / 2/5 pound of chicken per person = x pounds of chicken
To solve for x, we can multiply both sides of the equation by 2/5 pound of chicken per person:
8 people * 2/5 pound of chicken per person = x pounds of chicken
x = 2 pounds of chicken
Therefore, 2 pounds of chicken are required to feed 8 people.

Maureen has two hollow containers. One is a 5 cm cube and the other is a cylinder of radius 2 cm. She completely fills the cube with water and then pours it into the cylinder.
What is the depth of the water in the cylinder? Give your answer in cm correct to 3 significant figures.
You can assume that the cylinder is tall enough to hold all the water from the cube.
Answer:
it's 9.947
Step-by-step explanation:
for this we need an equation which contain height in it so we used volume in both so we get height
π2^2h=5*5*5
π4h=125
h=9.947
To find the depth of water in the cylinder, calculate the volume of the cube and then use that volume to find the height of the cylinder.
Explanation:To find the depth of water in the cylinder, we need to calculate the volume of the cube and then use that volume to find the height of the cylinder.
The volume of a cube is given by V = s^3, where s is the length of a side.
The volume of the cube is (5 cm)^3 = 125 cm^3.
Now, we can use the formula for the volume of a cylinder, V = πr^2h, where r is the radius and h is the height.
Using the volume of the cube as the volume of the water in the cylinder, we get 125 cm^3 = π(2 cm)^2h. Solving for h, we find h = 9.278 cm.
Therefore, the depth of the water in the cylinder is approximately 9.278 cm.
