Answer:
In 1 hour run:
4 4/5 miles
Step-by-step explanation:
2 4/5 = 2 + 4/5 = 10/5 + 4/5 = (10+4)/5 = 14/5
Proportions:
14/5 miles ⇒ 7/12 hour
A miles ⇒ 1 hour
A = (14/5 miles)(1hour) / (7/12 hour)
A = (14/5)/(7/12)
A = (14*12) / (5*7)
A = 168 / 35
A = 140/35 + 28/35
A = 4 + 28/35
A = 4 + 4/5
A = 4 4/5 Miles

Gail is selling Girl Scout cookies. This week Mrs. Martin bought 3 boxes, Mr. Leesville bought 4 boxesm, and her friend Carroll bought 1 box. Mr. Millbrook cannot eat cookies so he gave a $7 donation to Gail's troop. If Gail sold 10 boxes last week and the amount of money she collected last week equals the amount of money she collected this week, write and solve an equation to determine how much each box of cookies costs.
Answer:
Let's assume that the cost of each box of cookies is "x" dollars.
Based on the given information, Gail sold a total of 3 + 4 + 1 = 8 boxes of cookies this week, and Mr. Millbrook gave a $7 donation. Therefore, the total amount of money collected this week is:
8x + 7
Since we know that Gail sold 10 boxes of cookies last week and collected the same amount of money, we can set up an equation:
10x = 8x + 7
Solving for x, we get:
2x = 7
x = 3.50
Therefore, each box of Girl Scout cookies costs $3.50.

prove by induction that if we remove the root of a k-th order binomial tree, it results in k binomial trees of the smaller orders. you can only use the definition of bk. per the definition, bk is formed by joining two bk−1 trees.
To prove that removing the root of a k-th order binomial tree results in k binomial trees of smaller orders, we will use mathematical induction.
Base case: For k = 1, removing the root of a 1st order binomial tree results in zero smaller binomial trees, which is true.
Inductive hypothesis: Assume that removing the root of a k-th order binomial tree results in k binomial trees of smaller orders, for some positive integer k.
Inductive step: We want to prove that removing the root of a (k+1)-th order binomial tree results in (k+1) binomial trees of smaller orders.
By definition, a (k+1)-th order binomial tree, denoted by B(k+1), is formed by joining two k-th order binomial trees, denoted by Bk, with one of them as the leftmost child of the root of the other. Let us remove the root of B(k+1) to obtain a new binomial tree, denoted by B'.
Since B(k+1) is formed by joining two k-th order binomial trees, we can apply the inductive hypothesis to each of them to obtain that removing their roots results in k smaller binomial trees each. Let these smaller binomial trees be denoted by B1, B2, ..., Bk and C1, C2, ..., Ck,
respectively.
Now, consider B' and observe that it is a k-th order binomial tree, since it has k children, each of which is a smaller binomial tree. Moreover, B' is obtained from B(k+1) by removing the root, which is the parent of the two k-th order binomial trees Bk and Ck. Thus, we have decomposed B' into k smaller binomial trees, namely B1, B2, ..., Bk and C1, C2, ..., Ck.
Therefore, we have shown that removing the root of a (k+1)-th order binomial tree results in (k+1) binomial trees of smaller orders, which completes the induction.

a heavy rope, 30 ft long, weighs 0.7 lb/ft and hangs over the edge of a building 80 ft high. (a) how much work w is done in pulling the rope to the top of the building?
A heavy rope, 30 ft long, weighs 0.7 lb/ft and hangs over the edge of a building 80 ft high, the work done in pulling the rope to the top of the building is 1785 ft-lb.
To calculate the work done in pulling the rope to the top of the building, we need to use the formula:
W = F x d
where W is the work done, F is the force applied, and d is the distance over which the force is applied.
In this problem, we can calculate the force required to pull the rope as the product of its weight per unit length (0.7 lb/ft) and the length of the rope (30 ft). Thus, the force required is:
F = 0.7 lb/ft x 30 ft = 21 lb
To calculate the distance over which the force is applied, we need to calculate the total length of the rope that needs to be lifted. This can be found using the Pythagorean theorem, as follows:
l = √(30^2 + 80^2) = 85 ft
So the distance over which the force is applied is 85 ft.
Now we can substitute the values for F and d into the formula for work to get:
W = F x d = 21 lb x 85 ft = 1785 ft-lb
This calculation shows how the formula for work can be used to calculate the energy required to lift an object against gravity over a given distance.

C. (c) 3.14 inches
D. D 5.24 inches
The approximate arc length of one slice of pic is 5.24 inches according to the circle circumference.
Let us assume that the pic is equally cut into 6 pieces. Also given that the diameter of the pie is 10 inches.
Diameter (D)=10.
So the radius will be D/2.
Radius (R)=10/2=5.
The pie's circumference is given by:
C=2πR
C=2π*5
C= 10π (in)
Because the pie is divided into six pieces, the circumference of the pie is divided into six equal-length arcs. So,
Length of Arc (L)= 10π/6
L = 5π/3
L= 5(3.14)/3
L=5.234=5.24

Mr. Mackinson has to choose 2 students to lead the class field trip. If he draws from a list of 6 boys and 6 girls, what is the probabilty that the names of 2 girls will be drawn?
The required probability of Mr. Mackinson choosing the names of 2 girls is approximately 0.2273.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
The total number of ways to choose any 2 students from a group of 12 is given by the combination formula:
C(12,2) = 12! / (2! * 10!) = 66
This means there are 66 total ways for Mr. Mackinson to choose any 2 students from the class.
To calculate the probability of choosing 2 girls, we need to count the number of ways to choose 2 girls from the group of 6 girls. We can use the combination formula again:
C(6,2) = 6! / (2! * 4!) = 15
This means there are 15 ways for Mr. Mackinson to choose any 2 girls from the class.
So the probability of Mr. Mackinson choosing 2 girls is:
P(2 girls) = number of ways to choose 2 girls / total number of ways to choose 2 students
= C(6,2) / C(12,2)
= 15 / 66
= 0.2273

You order a pizza with a 12” diameter. What is the area of the pizza?
What is the radius of a pizza that is 25% larger??
Pls help
Answer:
1. The formula for the area of a circle is given by A = πr^2, where r is the radius of the circle. To find the area of the 12" pizza, we first need to find the radius:
r = 12 / 2 = 6 inches
The area of the pizza is then:
A = πr^2 = π * 6^2 = 36π square inches
2. To find the radius of a pizza that is 25% larger, we can first find the amount by which the radius will increase:
increase = 6 * 0.25 = 1.5 inches
The new radius will then be:
new_r = 6 + 1.5 = 7.5 inches.
Step-by-step explanation:
Answer:
113.1, 8
The equation to find the area of a circle is:
Area = π (d/2)^2Now we can input 12 into the equation:
Area = π (12/2)^2Area = 113.1To find the radius of a pizza that is %25 larger, we can use this equation:
Radius × 1.25 = new radiusWhy do we multiply by 1.25?Well, that's a good question! If we were to multiply by 0.25, the radius would get smaller, instead of bigger. We add the 1.0 because we have to add the original radius, not just the added length.
Fitting the radius into the equation:
6 × 1.25 = 8Therefore, the area of the pizza is 113.1, and the radius of a pizza that is %25 larger is 8.

Sarah Meeham blends coffee for Tasti-Delight. She needs to prepare 120 pounds of blended coffee beans selling for $4. 17 per pound. She plans to do this by blending together a high-quality bean costing $5. 25 per pound and a cheaper bean at $2. 00 per pound. To the nearest pound, find how much high-quality coffee bean and how much cheaper coffee bean she should blend
Sarah should blend 80.5 pounds of the high-quality beans and 39.5 pounds of the cheaper beans to make 120 pounds of blended coffee.
In this problem, we are given that Sarah Meeham needs to prepare 120 pounds of blended coffee beans to sell at a rate of $4.17 per pound. She plans to blend two types of coffee beans: a high-quality bean costing $5.25 per pound and a cheaper bean costing $2.00 per pound.
Let x be the number of pounds of the high-quality coffee beans needed and y be the number of pounds of the cheaper coffee beans needed. Since we need 120 pounds of the blended coffee, we have:
x + y = 120
The cost of the blended coffee is $4.17 per pound. This means that the total cost of the blended coffee is:
4.17(120) = 501.6
We can also find the cost of the high-quality and cheaper beans in terms of x and y:
5.25x is the cost of the high-quality beans
2.00y is the cost of the cheaper beans
The total cost of the two types of beans is the sum of their individual costs:
5.25x + 2.00y
Since we need 120 pounds of the blended coffee, we can set up the following equation using the above expressions for total cost:
5.25x + 2.00y = 501.6
Now, we can use the system of equations consisting of x + y = 120 and 5.25x + 2.00y = 501.6 to solve for x and y. One way to do this is by substitution:
x = 120 - y (from the first equation)
5.25(120 - y) + 2.00y = 501.6 (substituting x in the second equation)
Simplifying and solving for y, we get:
630 - 5.25y + 2.00y = 501.6
3.25y = 128.4
y ≈ 39.5
Now we can use this value of y to find x:
x = 120 - y
x = 120 - 39.5
x ≈ 80.5
