How many pieces 1/3 of a foot each can I make out of 7 feet of rope?
Answers
In order to find how many pieces of 1/3 feet rope you can make out of 7 feet rope, you have to divide 7 feet by 1/3 feet.
7/ (1/3) = 21 pieces
Therefore, you can make 21 1/3 – feet ropes.
7 ÷ [tex] \frac{1}{3} [/tex]
[tex]7 * \frac{3}{1} = 21[/tex] pieces
There are twice as many liters of water in one container as in another. If 8 liters of water are removed from each of the two containers, there will be three times as many liters of water in one container as in the other. How many liters of water did the smaller container have to begin with?
Answers
This would make '2x' litres of water in the larger container.
After taking 8 litres from both containers, the following equation can be written:
(2x-8) = 3 (x-8)
Open the brackets:
2x-8 = 3x-24
Collect like terms:
x = 16

Answers
s • s
We can also write this as
s^2
So, for any side length “s”, we can make a function, A(s), such that
A(s) = s^2
Now that we have a quadratic equation for the area of a square, let’s go ahead and solve for the side lengths of a square with a given area. In this case, 225 in^2
225 = s^2
Therefore,
s = sqrt(225)
s = 15
So, the dimensions are 15 x 15 in

QS = QT -- FALSE. S lies inside circle Q, so is closer to the center than T, which lies on the circle. (For some choice of point R, S might lie on the circle, but because this statement is not always true, it must be considered false.)

A conical hat has a radius of 7 inches and a height of 14. What’s the slant height
Answers
The slant height of a conical hat with a radius of 7 inches and a height of 14 inches is found by using the Pythagorean theorem, leading to a slant height of approximately 15.65 inches.
To find the slant height of a conical hat with a radius of 7 inches and a height of 14 inches, we use the Pythagorean theorem for the right triangle formed by the radius, height, and slant height of the cone. The slant height is the hypotenuse of this right triangle, while the radius and the height are the two legs.
The formula for the Pythagorean theorem is:
a^2 + b^2 = c^2
Where:
a is the radius of the cone (7 inches),
b is the height of the cone (14 inches), and
c is the slant height of the cone (what we are trying to find).
Substituting the values into the formula, we get:
7^2 + 14^2 = c^2
49 + 196 = c^2
245 = c^2
To find c, we take the square root of both sides:
c = √245
The slant height (c) is then calculated to be:
c ≈ 15.65 inches

n cold climate areas, trucks are used to disperse salt on the roads in order to de-ice the roads, making them safe for travel. In some cases, cone- shaped sheds store the salt during the off-season, or until the roads need to be de-iced. This large salt storage shed sits 12 feet above the ground and holds approximately 51.4 cubic feet of salt. To the nearest hundredth of a foot, what is the radius of the large storage shed? Use 3.14 for . In your final answer, include all of your calculations.
Answers
You will substitute in the information you know and then solve for the radius(r).
Please see the attached picture for the steps necessary to get an approximate radius of 2.02 ft as the radius.
The radius of the large storage shed is approximately 2.023 feet to the nearest hundredth of a foot.
To find the radius of the large storage shed, we need to use the formula for the volume of a cone, which is given by: [tex]\[ V = \frac{1}{3} \pi r^2 h \][/tex]
where V is the volume, r is the radius of the base, h is the height and [tex]\( \pi \)[/tex]is approximately 3.14. We are given that the volume V is 51.4 cubic feet and the height h is 12 feet. We need to solve for r.
First, let's rearrange the formula to solve for r: [tex]\[ r^2 = \frac{3V}{\pi h} \][/tex]
Now, plug in the given values:
[tex]\[ r^2 = \frac{3 \times 51.4}{3.14 \times 12} \][/tex]
[tex]\[ r^2 = \frac{154.2}{37.68} \][/tex]
[tex]\[ r^2 \approx 4.093 \][/tex]
Now, take the square root of both sides to find r:
[tex]\[ r \approx 2.023 \][/tex]
So, the radius of the large storage shed is approximately 2.023 feet to the nearest hundredth of a foot.
You put $5000 in an account. The account earns $2250 simple interest in 10 years. What is the annual interest rate?
The annual interest rate is
Answers
The annual interest rate is 4.5%.
What is the simple interest?Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
Simple interest is calculated with the following formula: S.I. = (P × R × T)/100, where P = Principal, R = Rate of Interest in % per annum, and T = Time.
Given that, principal =$5000, simple interest=$2250 and time period= 10 years.
Here, 2250= (5000×R×10)/100
225000=50000R
R=225000/50000
R=4.5%

Nolan used the following procedure to find an estimate for the square root of 18.
Step 1: Since 4^2=16 and 5^2= 25 and 16 < 18 < 25, the square root of 18 is between 4 and 5.
4.1^2=16.81
4.2^2=17.64
4.3^2=18.49
4.4^2=19.36
Step 3: Since 18.49 rounds to 18, 4.3 is the best approximation for the square root of 18.
In which step, if any, did Nolan make an error?
A) In step 1, the square root of 18.
is between 4 and 5 because the square root of 18 equals about 20 and 4 times 5= 20.
B) In step 2, he made a calculation error when squaring.
C) In step 3, he should have determined which square is closest to 18.
D) Nolan did not make an error.
Answers
Nolan correctly identified the square numbers before and after 18.
The square roots of them are 4 and 5.
Clearly, square root of 18 should lie between 4 and 5 only.
He, then carefully squared 4.1, 4.2, 4.3 etc. and identified that 4.3 squared is nearer to 18.
Since, Nolan is finding estimated square root, his steps are cool and he didn't make any error.

Find the cardinal number for the following sets.
A = {102, 103, 104, 105,..., 155}
B = {102, 104, 106, ..., 252}
Answers
For example, if P={1,4,6}, cardinality is 3 because there are three member in the set.
For A, the numbers run consecutively from 102 to 155, so there are (155-102)+1=54 members. The cardinality is therefore 54
Similarly, for B={102,...252}, there are (252-102)+1=151 members. So the cardinality is 151.
Find the surface area of a pyramid with base sides of 2.5 inches and a slant height of 3 inches.
Answers
The formula to find the surface area of a pyramid is as follows:
[tex] \frac{1}{2} [/tex] pl + B
In this formula p represents the perimeter of the pyramid's base, l is the slant height, and B is the area of the base.
So, we know that the length of the base sides is 2.5 inches and the slant height (or l) is 3 inches.
The first thing we can do is solve for p or the perimeter of the base. To find the perimeter, you can either add up each of the sides or since it's a square just multiply the side length by 4; both of these options will give you the same answer.
2.5+2.5+2.5+2.5 = 10 2.5*4 = 10
So, we now know that p = 10 inches.
Next, we can solve for B or the area of the base. To do this, we take the length of the base * the width of the base, or in this case just 2.5*2.5; this gives us 6.25 inches
We now have the value of B which is 6.25 inches.
Now that we have all the elements, we can plug the values into the formula!
So, the formula originally is [tex] \frac{1}{2} [/tex] pl + B and with the values we just found plugged in it becomes [tex] \frac{1}{2} [/tex] (10)(3) + (6.25).
And now all we have to do is solve!
[tex] \frac{1}{2} [/tex] (10)(3) + (6.25)
[tex] \frac{1}{2} [/tex] (30) + (6.25).
15 + (6.25).
21.25
And there you have it! The surface area of a pyramid with base sides of 2.5 inches and a slant height of 3 inches is 21.25 inches.
Hope you find this helpful!
Final answer:
The surface area of a pyramid with a base side of 2.5 inches and a slant height of 3 inches is calculated by finding the area of the base and the four triangular faces separately and then adding them together, resulting in a total surface area of 21.25 square inches.
Explanation:
To find the surface area of a pyramid with a square base of 2.5 inches and a slant height of 3 inches, we need to calculate the area of the base and the area of the four triangular faces.
For the base, which is a square:
Area of base = side × side = 2.5 inches × 2.5 inches = 6.25 square inches
For each triangular face:
Area of one triangle = (base × slant height) / 2 = (2.5 inches × 3 inches) / 2 = 3.75 square inches
Since there are four such triangles, we multiply the area of one triangle by 4:
Total area of four triangles = 3.75 square inches × 4 = 15 square inches
Finally, add the area of the base and the total area of the triangular sides to get the total surface area:
Total surface area = area of base + total area of triangles = 6.25 square inches + 15 square inches = 21.25 square inches
The surface area of the pyramid is therefore 21.25 square inches.
