Answer:

[tex]\frac{9}{8} [W]\ and \ \frac{3}{4} [S].[/tex]

Step-by-step explanation:

1. if the weight of Whisters is 'w', then the weight of Scamp is 'w-3/8'; then

2. it is possible to make up the equation:

[tex]w+w-\frac{3}{8}=1\frac{7}{8};[/tex]

3. if to solve this equation, then w=9/8 - this is the weight of Whiskers;

the weight of Scamp is 9/8-3/8=6/8=3/4 [pounds].

Therefore, we will need volume approximately 694.4 cubic feet of sand to fill the pit to a depth of 30 inches.

The volume of a three-dimensional item, which is measured in cubic units, describes how much room it occupies. Two instances of cubic units are cm3 and in3. To the contrary hand, a measurement of a thing's mass indicates how much material it includes. Typically, the weight of an item is measured in mass units the same as pounds or kilograms.

Here,

a.

Length: 30 feet 2 inches

Width: 9 feet 2 inches

Height: 30 inches (since the sand needs to be 30 inches deep)

To calculate the amount of wood required, we need to find the perimeter and area of the base of the frame.

Perimeter = 2(Length + Width) = 2(30 ft 2 in + 9 ft 2 in) = 2(39 ft 4 in) = 78 ft 8 in

Area of the base = Length × Width = (30 ft 2 in) × (9 ft 2 in) = 275 ft²

The amount of wood needed to surround the pit can then be calculated by finding the total surface area of the wooden frame.

Total surface area = 2(L × H) + 2(W × H) + Area of the base

= 2(30 ft 2 in × 30 in) + 2(9 ft 2 in × 30 in) + 275 ft²

≈ 240.5 square feet

Therefore, we will need approximately 240.5 square feet of wood to surround the pit.

b.

Length: 30 ft 2 in = (30 × 12) + 2 = 362 inches

Width: 9 ft 2 in = (9 × 12) + 2 = 110 inches

Depth: 30 inches

The volume of sand needed to fill the pit can be calculated using the formula:

Volume = Length × Width × Depth

Substituting the values, we get:

Volume = 362 in × 110 in × 30 in

= 1,198,800 cubic inches

To convert cubic inches to cubic feet, we divide by 12^3 (since there are 12 inches in a foot, and we need to cube this conversion factor):

Volume = 1,198,800 in³ ÷ (12³ in³/ft³)

= 694.4 ft³ (rounded to one decimal place)

Therefore, we will need approximately 694.4 cubic feet of sand to fill the pit to a depth of 30 inches.

[tex] \frac{7}{8} = \frac{14}{16} [/tex]

because 7 times 2 is 14 and 8 times 2 is 16, so he got to the correct conclusion

Tony says...

[tex] \frac{1}{7} + \frac{1}{14} = \frac{14}{16} [/tex]

There's no way to get this answer because neither 7 or 14 goes evenly into 16.

Tony got the correct answer, but his addition is incorrect for that said reason

Answer:

Tony's addition is correct.

Step-by-step explanation:

Tony needs to add 7 two times, since the customers ate 7 slices of out both pizzas. And, 7 + 7 is 14, and you need to also count the total slices of pizza, which is 16. So, the fraction would be 14/16, which can be simplified into 7/8, which is just 14/16 multiplied by 2.

Answer:

x = 4/3

y = 7/3

Step-by-step explanation:

7x - y = 7

x + 2y = 6

Times the second equation by -7

7x - y = 7

-7x - 14y = -42

-15y = -35

y = 7/3

Now put 7/3 back in for y and solve for x

x + 2(7/3) = 6

x + 14/3 = 6

x + 14/3 = 18/3

x = 4/3

Let's check

4/3 + 2(7/3) = 6

4/3 + 14/3 = 6

18/3 = 6

6 = 6

So, x = 4/3 and y = 7/3 is the correct answer.

Fixed rate only have fixed payments for at least the first 6 years. Therefore, option A is the correct answer.

A fixed-rate mortgage is a home loan option with a specific interest rate for the entire term of the loan. Essentially, the interest rate on the mortgage will not change over the lifetime of the loan and the borrower's interest and principal payments will remain the same each month.

An adjustable-rate mortgage, also called an ARM, is a home loan with an interest rate that adjusts over time based on the market. ARMs typically start with a lower interest rate than fixed-rate mortgages, so an ARM is a great option if your goal is to get the lowest possible mortgage rate starting out.

A balloon mortgage begins with fixed payments for a specific period and ends with a final lump-sum payment. The one-time payment is called a balloon payment because it's much larger than the beginning payments.

Answer: The circumference of the smaller circular base of the cone can be found using the formula:

C = 2 * π * r

where "r" is the radius of the circle. The radius can be found using the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the longest side (the hypotenuse).

Since the cut plane is parallel to the base of the cone, the height of the cone and the height of the remaining section of the cone are equal. Let's call this height "h". Then, using the Pythagorean theorem, we have:

r^2 + (h/2)^2 = (h/2)^2

Simplifying, we get:

r^2 = (h/2)^2

Taking the square root of both sides:

r = h/2

Substituting "h/2" for "r" in the formula for the circumference:

C = 2 * π * (h/2) = π * h

Since we do not have a specific value for "h", we cannot find an exact value for the circumference. However, based on the given options, the closest approximate value to π * h is c) 3.36 feet.

Step-by-step explanation:

The required function of s and decreasing function of s are  a) h(s) = V / (s²) b) dh/ds = -2V / (s³).

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

(a) We know that the volume of the box, V, is given by the product of its height, h, and its base area, which is s².

we can write the equation:

V = h * s²

Solving for h, we get:

h = V / (s²)

So the height of the box, h, as a function of s can be expressed as

h(s) = V / (s²)

(b) To determine whether h(s) is an increasing or decreasing function of s, we need to look at the sign of its derivative.

The derivative of h(s) with respect to s is given by:

dh/ds = -2V / (s³)

Since the derivative is negative for all positive values of s, h(s) is a decreasing function of s.

The triangle is not a right triangle because the Pythagorean Theorem (c² = a² + b²) is not satisfied.

What is the Pythagorean Theorem?

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base, and Hypotenuse.

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side, which is opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, the given values of a and b do not satisfy the equation:

c² = a² + b²

(86)² = (76.5)² + (40.1)²

7396 = 5862.25 + 1608.01

7396 = 7470.26

This means that the triangle with sides a = 76.5 yd, b = 40.1 yd, and c = 86 yd is not a right triangle.

The proceeds of the note can be calculated by multiplying the face amount by the interest rate. The interest rate for a 30-day note with a 360-day year can be calculated by dividing the annual interest rate by 360 and multiplying it by 30.

Proceeds of the note = 55,200 * (5/100/360 * 30) = 55,200 * (5/12) = 4,600

The discounted note can be calculated by subtracting the proceeds from the face amount.

Answer: The matrix A of the linear transformation T(f(t)) = f''(t) + 3f'(t) + 7f(t) from the space spanned by the functions cos(t) and sin(t) into itself with respect to the basis {cos(t), sin(t)} can be found by computing the images of the basis vectors under T and expressing those images as linear combinations of the basis vectors.

We have:

T(cos(t)) = -cos(t)'' - 3cos(t)' - 7cos(t) = -cos(t) - 3(-sin(t)) - 7cos(t) = -8cos(t) - 3sin(t)

T(sin(t)) = -sin(t)'' - 3sin(t)' - 7sin(t) = -sin(t) - 3cos(t) - 7sin(t) = -8sin(t) + 3cos(t)

So, with respect to the basis {cos(t), sin(t)}, the matrix A is:

A = [ -8, -3; 3, -8 ]

This is the matrix representation of the linear transformation T with respect to the basis {cos(t), sin(t)}.
