Given that Betty saves $161 per month which is $141 less than Jack per month. find the amount that Jack will save in 2 years.
First, find how much Jack saves. We can do this buy adding 141 to 161 since Betty saves 141 less meaning we can reverse it by adding it.
141 + 161 = 302
Now, that we know how much Jack saves per month.
Then, we have to find out how many months are in 2 years.
We already know that there is 12 months in a year, so for 2 years, we can simply multiply by 2.
12 x 2 = 24
Therefore, there are 24 months in two years.
Lastly, multiply 24 months by the amount that Jack saves to get the amount in total.
24 x 302 = 7,248
Thus, Jack will save approximately $7,248 in 2 years.
Answer:
Jack will save $7248 in 2 years.
Step-by-step explanation:
Because we know that Betty saves $161 a month, but it's $141 less than Jack saves each month.
Adding $141 to $161 let's us know how much Jack saves.
$141 + $161 = $302
Jack saves $302 each month.
There are 24 months in 2 years.
$302 × 24 = $7248.

A trucking company needs to move a pile of dirt. The dirt is stored in a pile shaped like a cone. The pile is 12 yards high, and its base has a diameter of 8 yards. How many truckloads will the company need, if each truck holds 6.28yd3 of dirt?
Answer:
it will take 96 truckload trips to move the entire pile of dirt.
Step-by-step explanation:
The formula for the volume of a cone of height h and radius r is
V = πr²h. Here, the radius, r, is half the given diameter, or r = d/2, or r = (8 yds)/2, or 4 yds, and the height is 12 yds. Thus, in this case, the volume of the conical pile of dirt is
V = π(4 yd)²·12 yd, or
V = 3.14(16 yd²)(12 yd), or
V = 602.88 yd³
If each truck holds 6.28 yd³ and we want to know how many truckloads the company needs in order to move the conical pile, we divide the above volume (V) by 6.28 yd³:
V 602.88 yd³
------------- = --------------------------------------- = 96
6.28 yd³ (6.28 yd³ per truckload)
We interpret this to mean that it will take 96 truckload trips to move the entire pile of dirt.
The number of truckloads the company will need is A = 32 truckloads
What is a Cone?A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the center of base) called the apex or vertex.
The volume of a cone is given by the equation
Volume of Cone = ( 1/3 ) πr²h
where r is the radius of the cone
h is the height of the cone
Surface area of the cone = πr ( l + r )
where l = √ ( b² + r² )
Given data ,
The first step is to find the volume of the pile of dirt using the formula for the volume of a cone: V = ( 1/3 ) πr²h, where r is the radius of the base and h is the height.
The height of the cone is given as 12 yards, and the diameter of the base is 8 yards, so the radius is half of that, or 4 yards. Plugging in these values, we get:
V = (1/3)π (4 yards)² (12 yards)
V ≈ 201.06 yards³
Next, we need to find out how many truckloads the company will need.
We know that each truck can hold 6.28 cubic yards of dirt, so we can divide the total volume of dirt by the volume of one truckload to find the number of truckloads needed:
201.06 cubic yards / 6.28 cubic yards/truckload ≈ 31.99 truckloads
Since the company can't order a fractional number of truckloads, they will need to round up to the nearest whole number.
Hence , the company will need 32 truckloads to move the pile of dirt

If using the method of completing the square to solve the quadratic equation x^2+15x+25=0x
2
+15x+25=0, which number would have to be added to "complete the square"?
Answer:
x = -15/2 ± (1/2)*5√5
Step-by-step explanation:
I will assume that you meant x^2+15x+25=0.
To complete the square, take half of the coefficient of x, square the result, add this square into the equation after '15x,' and then subtract the square from the result:
x^2+15x+25=0 => x^2 + 15x + (15/2)^2 - (15/2)^2 + 25 = 0.
Rewrite the first two terms as (x + 15/2)^2 - 225/4 + 100/4 = 0, or
(x + 15/2)^2 - 125/4 = 0
Taking the square root of both sides, we obtain the solutions:
x + 15/2 ±√[125/4], or
x = -15/2 ± (1/2)*5√5
The quadratic equation x²+15x+25=0, (15/2)² is a number to be added to "complete the square"
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The quadratic equation x²+15x+25=0
x²+15x+(15/2)²+25-(15/2)²=0
(x+15/2)²+25-225/4
(x+15/2)²+(100-225)/4
(x+15/2)²+(-125/4)
(x+15/2)²-(√125/√4)²
(x+15/2+√125/√4)(x+15/2-√125/√4)
(x+15/2+√125/2)(x-15/2-√125/2)
(x+(15+√125)/2)(x-(15+√125)/2)
Hence (15/2)² is a number to be added to "complete the square"

Given the functions 8m², 4m and 10m⁴, in order to find the greatest common factor, we will find a factor common to all the functions as shown;
8m² = 2*2*(2*m)*m
4m = 2*(2*m)

Mr. Maxwell White bought a house at the cost of GHȼ250,000,000.00. He paid 20% of the cost out of his own resources an took a loan for the remaining amount at 2 1/2 % simple interest per annum. Calculate the total amount Mr. Maxwell White paid for the house, if he paid the loan 8 years later.
Answer:GHȼ290,000,000
Step-by-step explanation:
Given the following :
Cost of house = 250,000,000
Amount paid out of his own resources = 20% of house cost
Amount loaned = 250,000,000 - (20% of 250,000,000)
Rate = 2 1/2% = 5/2% = 0.025
Period or time = 8 years
Therefore,
Amount paid out of his own resources :
0.2 × 250,000,000 = 50,000,000
Amount loaned = (250,000,000 - 50,000,000) = 200,000,000 = principal
Simple Interest on loan = (principal × rate × time)
200,000,000 × 0.025 × 8 = 40,000,000
Total amount paid back= (200,000,000 + 40,000,000) = 240,000,000
Total amount paid for the house :
Total loan paid + amount paid from own resource:
240,000,000 + 50,000,000 = 290,000,000

A trampoline gym charges $6 for 1/2 of an hour. At that rate, what does 1 hour cost?
Answer:
Step-by-step explanation:
12
One hour's cost for the trampoline gym will be $12.
What is ratio?The ratio can be defined as the number that can represent one quantity as a percentage of another. They can be compared only when the two numbers in a ratio have the same unit. Ratios are used to compare two objects.
Given, A trampoline gym charges $6 for 1/2 of an hour.
Since,
For 1/2 hour gym charges = 6$
So from the definition of the ratio
Thus,
For 1-hour gym will charge = 6*2
For 1 hour gym will charge = 12$
therefore, One hour cost for the gym will be $12.

A. David notices that the shape of the Ligersville toxic dump site is somewhat like a triangle. He claims that he can approximate the perimeter of the dump site without doing any extra measurements. What assumption about side AB of the dump site would David need to make in order to justify his claim?
B. Based on the assumption in part A, determine the approximate length of side AB of the dump site. Explain your reasoning in at least two sentences.
C. Determine the approximate perimeter of the Ligersville toxic dump site. Explain your reasoning.
Answers and Step-by-step explanations:
A. David would need to assume that side AB is the hypotenuse of the almost-right triangle that A, B, and C make. That way, he can use the Pythagorean Theorem to solve for AB.
B. AB² = 24² + 32² = 1600 ⇒ AB = √1600 = 40 yards
We can use the Pythagorean Theorem because we assume that ABC is in the form of a right triangle, with AB as the hypotenuse. Then since whenever we have a right triangle, we can use the Pythagorean Theorem to solve for an unknown side, that applies here as well.
C. The approximate perimeter is 24 + 32 + 40 = 96 yards. Using the approximation of AB from part B, we simply add up all the side lengths of this "triangle", as that is the definition of "perimeter". Thus, when we add them all together, we get a total of 96 yards.
Answer:
A. Assumption: length of the curve AB is equal to the hypotenuse of the triangle formed AB was a straight line.
B. 40 yards
C. 96 yards
Step-by-step explanation:
A. Assumption: length of the curve AB is equal to the hypotenuse of the triangle formed AB was a straight line.
B. AB² = 32² + 24²
AB² = 1600
AB = 40
Since we have assumed that AB is equal to the hypotenuse, we can use pythagoras theorem to find an approximate length of AB
C. Perimeter is the sum of all lengths:
32 + 24 + 40 = 96

Answer: 15cm.
Step-by-step explanation:
Hi, to answer this question we have to multiply the real height of the kite (1.5m) by the scale factor of the drawing (10):
Mathematically speaking:
Since 1 m = 10 cm
So:
1.5 m x 10 cm/m = 15 cm
The kite is 15 centimeters tall in the drawing.

Find the length of the third side to the nearest tenth.
Answer:
5.3
Step-by-step explanation:
You use the Pythagoras theorem which is a^2+b^2=c^2.
Since you're solving for a side length that's not the hypotenuse you will manipulate the equation to c^2-a^2=b^2. From here you just plug in numbers.
8^2 - 6^2 = b^2
64 - 36 = b^2
b = sqrt(28)
b = 5.2915.... = 5.3
