The surface area of a solid object is a measure of the total area that the surface of the object occupies.

The surface area of a solid object is a measure of the total area that the surface of the object occupies.

Area = length x breadth

To find the surface area of the postal box, we first find the area of each sides of the box and add them together.

Top and bottom area = L x B = 12 x 8 = 96inches² x 2 = 192inches²

Front and back areas = L x B = 12 x 2 = 24inches² x 2 = 48inches²

Area of the sides = L x B = 8 x 2 = 16inches² x 2 = 32inches²

Total surface area will be 192 + 48 + 32 = 272inches²

Step-by-step explanation:

Answer:

I think that's right. I checked my answer and proved it on that sheet.

The two-sided limit exists as long as the limits from either side also exist and are equal. So to compute the limit, you have to compute the one-sided limits,

\(\displaystyle\lim_{x\to0^-}f(x)\)

\(\displaystyle\lim_{x\to0^+}f(x)\)

f(x) has a different definition and thus different behavior as x approaches 0 depending on which direction x is approaching 0:

• When x approaches 0 from the left (or from below), you use the definition of f for x < 0, so

\(\displaystyle\lim_{x\to0^-}f(x) = \lim_{x\to0}(-x-2) = -2\)

• When x approaches 0 from the right (or above), you use the other definition, so

\(\displaystyle\lim_{x\to0^+}f(x) = \lim_{x\to0} \left(\frac x2-2\right) = -2\)

The limits from either side match, so the two-sided limit exists and is also -2.

The correct statement is their corresponding sides have equal lengths, and the angle measures of triangle 2 are 0.25 times the corresponding angle measures of triangle 1.

What is property of similar triangle?

If the corresponding sides of two triangles have the same ratio and the corresponding angles are equal, then the triangles are similar.

They have parallel corresponding sides, and they have angles with the same measure.

Answer:

he can make 8 piles before he runs out and has 2 cards leftover

Step-by-step explanation:

The number that is equal to the difference of sum of both the sum is 325.

The multiples of 4 are 4,8,12,16,20...

The multiples of 3 are 3,6,9,12,15,...

Both the sequences are forming an Arithmetic progression(AP),

The sum of n terms of an AP is,

Sₙ = n/2(2a + (n-1)d)

Where,

n is the number of terms,

a is the first term,

d is the common difference.

So, For multiples of 3,

a = 3

d = 3

n = 25

So, putting values in the formula,

S₂₅ = 25/2(6+24x3)

S₂₅ = 975

For the multiples of 4,

a = 4

d = 4

n = 25

Putting values in the formula,

S'₂₅ = 25/2(8+24x4)

S'₂₅ = 1300

The difference in both the sums,

S'₂₅ - S₂₅ = 1300-975

S'₂₅ - S₂₅ = 325

The difference of the sum is 325.

The one or two other sequence to create FGHIJ from ABCDE are:

1. F, B+5=G, C+5=H, D+5=I, E+5=J.

2. Reverse ABCDE to get EDCBA

A sequence refers to an ordered list of items. It may be letters, numbers, or any other objects arranged in a particular order.

A sequence of rigid motions and dilations is a combination of transformations that preserve the original shape and size of a figure, but change its position, orientation, and scale.

To create the sequence FGHIJ from ABCDE, there are many possible sequences that can be used. Here are two:

Sequence 1:

Add 5 to each letter in ABCDE to get FGHIJ: A+5=F, B+5=G, C+5=H, D+5=I, E+5=J.

Sequence 2:

Reverse the order of the letters in ABCDE to get EDCBA.

Add 5 to each letter in EDCBA to get JIHGF: E+5=J, D+5=I, C+5=H, B+5=G, A+5=F.

Answer:

Diameter = 49

radius = 49/2

circumference of circle is = 2π r

The radius will grow at a rate of 1.269miles per hour.

Given that,

A ruptured tanker's oil leak propagates in a circle whose area grows at a constant rate of 9 mi2/hr.

To find : Radius growing at what rate when area is 4 mi2

The area of a circle can be represented by  A = π r²  ---> (i)

Differentiating both sides w.r.t time

da/dt = 2πr dr/dt ------------>(ii)

Dividing II by I , we have

(da/dt = 2πr dr/dt)  /  (A = π r²)

da/a = 2 * dr/r

Substituting the values

dr/r = 9/4*2 = 9/8

=1.125 mi per unit radius

or dr = 1.12 x 1.125 = 1.269 mi/hr

Here 1.12 mi is the radius , when area of circle is 4 mi²

The required original number that June was thinking of is 36.

Let's assume the original number June was thinking of is represented by "x". According to the problem, June doubles the original number (2x) and adds 18 to get an answer of 90. We can write this as the equation:

\(2x + 18 = 90\)

To find the value of x, we need to isolate it on one side of the equation. Let's subtract 18 from both sides:

\(2x = 90 - 18 \\ 2x = 72\)

Now, we divide both sides of the equation by 2 to solve for x:

\(x = 72 / 2 \\ x = 36\)

Therefore, the original number that June was thinking of is 36.

We have the lease of a building is for 10 years with an annual rent of $48 000.

We first determine the 7.5% for the first 5 years, for that we add the cost of the rent for 5 years, that is:

In 5 years the rent will be of $240 000, now we find the 7.5%:

Her commision for the first 5 years is going to be of $18 000.

Now we determine the 5% for the next 3 years, for this we determine the rent for 3 years:

The rent for 3 years adds $144 000, now we determine the 5%:

From this we have that the commission for the next 3 years will be of $7200.

And finally, we determine the rent for the two remaining years:

We have that the last two years the rent will be of $96000, now we determine the 3.5% of her commission during that time:

From this we have her commission for the last two years will be of $3360.

Finally we add all of the values of the commissions she will get:

From this we have that the total commision money she will be getting during those 10 years will be $28 560.

From the given graph, CE is longer than CD.

The length of the line segment bridging two locations in a plane is known as the distance between the points. d=√((x₂ - x₁)²+ (y₂ - y₁)²) is a common formula to calculate the distance between two points. This equation can be used to calculate the separation between any two locations on an x-y plane or coordinate plane.

Coordinates of E(8,6)

Coordinates of C(6,1)

Coordinates of D(3,-3)

x=8, y=6

x=6, y=1

x=3, y=-3

Distance CE=√{(8-6)² +(6-1)²} = √29

Distance CD=√{(6-3)² +(1+3)²}= √25=5

Therefore, CE is longer than CD.

(A) 4x² - 3x + 7 and (B) y² + √2 are polynomials with one variable and the rest are not.

A polynomial is a mathematical equation made up of coefficients and indeterminates that exclusively uses the operations of addition, subtraction, multiplication, or powers of positive numbers of the variables.

x² - 4x + 7 is an illustration of a quadratic with a solitary indeterminate x.

(A) 4x² - 3x + 7:

'x' is the only variable in the provided polynomial.

As a result, the polynomial 4x² - 3x + 7 has one variable.

(B) y² + √2:

'Y' is the only variable in the provided polynomial.

y² + √2 is a polynomial in one variable as a result.

(C) 3√t + t√2:

Since the power of the variable in the first term is 1/2, which is not a whole integer, 3√t + t√2 is not a polynomial.

(D) y + (2/y):

Because the power of the variable in the second term is -1, which is not a whole number, y + 2y⁻¹ is not a polynomial.

(E) x¹⁰ + y³ + t⁵⁰

Due to the fact that x, y, and t are all three variables, x¹⁰ + y³ + t⁵⁰ is not a polynomial in one variable.

Answer:

\( \boxed{\sf Length \ of \ the \ rectangle = 16 \ in} \)

Given:

Perimeter of rectangle = 48 in

Length = Twice the width

To Find:

Length of the rectangle

Step-by-step explanation:

Let width of the rectangle be 'w'.

So,

Length of the rectangle = 2w

\(\sf \implies Perimeter \ of \ rectangle = 2(Length + Width \\ \\ \sf \implies 48 = 2(2w + w) \\ \\ \sf \implies 48 = 2(3w) \\ \\ \sf \implies 48 = 6w \\ \\ \sf \implies 6w = 48 \\ \\ \sf \implies \frac{ \cancel{6}w}{ \cancel{6}} = \frac{48}{6} \\ \\ \sf \implies w = \frac{48}{6} \\ \\ \sf \implies w = \frac{8 \times \cancel{6}}{ \cancel{6}} \\ \\ \sf \implies w = 8 \: in\)

Width of the rectangle (w) = 8 in

Length of the rectangle = 2w

= 2 × 8

= 16 in
