The surface area of the sandbox assuming there is no lid is 21.3 feet

From the question, we are to determine the surface area of the sandbox

From the given information,

The dimension of the box is 3 feet by 4 feet

Thus,

Length = 4 feet

Width = 3 feet

and

The depth of the box is 8 inches

That is,

Height = 8 inches = 8/12 feet

Height = 2/3 feet

Now,

Using the formula for the surface area of a box

Surface area = (2lw + 2lh + 2wh)

If there is no lid,

The surface area becomes

Surface area = (lw + 2lh + 2wh)

Thus,

Surface area = (4×3 + 2×4×2/3 + 2×3×2/3)

Surface area = (12 + 16/3 + 4)

Surface area = (12 + 5.3 + 4)

Answer:

C

Step-by-step explanation:

Taking a square root of a number that doesn't have a square root like [tex]\sqrt{17}[/tex] will result in an infinite number of random digits which is an irrational number. Hence, C is the answer.

D isn't the answer because even though [tex]\sqrt{5}[/tex] is irrational, you're adding [tex]\sqrt{5}[/tex] and then subtracting [tex]\sqrt{5}[/tex] from the total sum. Hence the total sum would be 5+14.

5+[tex]\sqrt{5}[/tex]+14-[tex]\sqrt{5}[/tex] =5+14+[tex]\sqrt{5}[/tex]-[tex]\sqrt{5}[/tex]= 5+14 ==> 19 is a rational number

The expression which represents the sales price of the bracelet in terms of the sticker price is; s = 0.65p and the evaluation for a sticker price of $60 is; $39.

It follows from the task content that the bracelet has been discounted 35% from its sticker price.

Hence, the sales price of the bracelet is therefore; (100 - 35)% of sticker price, p.

Therefore, we have;

The average rate of change over the entire slide if the height of the slide is 2 feet is; -3.9

Average rate of change is defined as a measure of how much the function changed per unit, on average, over that interval.

First, we will calculate the average rate from x = 0 to x = 15:

We have:

R = ((80 - 10)/(0 - 15))

R = -4.667

Let us now calculate average rate of change for the entire interval supposing that the height of the slide is 2 feet,:

From x = 0 to x = 20, we have;

R = ((80 - 2)/(0 - 20))

R = -3.9

"complimentary" means together they have 90°.

"supplementary" means together they have 180°.

which can be easily and quickly found on any internet search.

7.

A = 70°

A + B = 90°

70 + B = 90

B = 90 - 70 = 20°

B + C = 180°

20 + C = 180

C = 180 - 20 = 160°

8.

A + B = 90°

B + C = 180°

C = 100°

B + 100 = 180°

B = 180 - 100 = 80°

A + 80 = 90

A = 90 - 80 = 10°

According to the solving the distance between two points is:

= 14.77

In coordinate geometry, the distance formula is used to calculate the actual distance between two points. The formula for calculating the distance between two locations (x1,y1) (x 1, y 1) and (x2,y2) (x 2, y 2) is D=(x2x1)2+(y2y1)2 D = (x 2 x 1) 2 + (y 2 y 1) 2.

The length of a line segment seems to be the distance between two locations. Congruent segments are those with the same length. By drawing a line with a ruler, we may compute the approximate distance between two points.

Given points: (-4, 6) and (3, -7)

X₁ = -4
Y₁ = 6
X₂ = 3
Y₂ = -7

We know that the distance between two points:

distance = √((x₂ - x₁)²+(y₂ - y₁)²)

              = √((3 - (-4))²+((-7) - 6)²)

              = √((3 + 4)²+(-13)²)

              = √((7)²+(-13)²)

              = √((49)+(169))

The equation is 6.5 (r-1) + 5.5  = 259 or 6.5 r - 1 = 259.

In this case, r stands for the overall number of rows.

The answer indicates that each row is 6.5 cm tall.

A formula known as an equation uses the equals sign (=) to express how two expressions are equal. The word "equation" and its cognates in other languages may have slightly different meanings. For instance, in French, an equation is defined as having one or more variables, while in English, any well-formed formula consisting of two expressions related with an equals sign is an equation. The task of solving an equation with variables entails figuring out which values of the variables cause the equality to hold true. The unknown variables are also known as the variables for which the equation must be solved, and the unknown variable values that fulfill the equality are known as the equation's solutions. Identity equations and conditional equations are the two types of equations.

The height of the top row is 6.5 - 1 = 5.5 cm.

Except for this row, there are total rows of = (r-1)

So, 6.5 is the total length of these rows (r-1)

The overall length of the wall is therefore equal to the sum of the (r-1) row and the top row.

However, once more in line with the inquiry,

Exactly 259 centimeters must be on the wall.

⇒ 259 = 6.5(r-1) + 5.5

⇒ 6.5(r-1) + 5.5 = 259

⇒ 6.5 r - 6.5 + 5.5 = 259

⇒ 6.5 r - 1 = 259

Answer:

RS = 33

Step-by-step explanation:

from the number line

RT = RS + ST ( substitute values )

46 = RS + 13 ( subtract 13 from both sides )

33 = RS

Answer:

RS = 33

Step-by-step explanation:

Given that,

→ ST = 13

→ RT = 46

Then the value of RS will be,

→ RS + ST = RT

→ RS + 13 = 46

→ RS = 46 - 13

→ [ RS = 33 ]

Hence, the value is 33.

The perimeter of the triangle ABC is approximately equal to 35.633 units.

In this problem we find the locations of the three vertices of the triangle and from which we have to calculate the length of each of the three sides. The perimeter is the sum of the three lengths. First, determine the vectors of each side:

AB = (2, - 9) - (- 3, 2)

AB = (5, - 11)

BC = (0, - 10) - (2, - 9)

BC = (- 2, - 1)

AC = (0, - 10) - (- 3, 2)

AC = (3, - 12)

Second, calculate the magnitudes of the three sides:

AB = √[5² + (- 11)²]
AB = √146

BC = √[(- 2)² + (- 11)²]

BC = 5√5

AC = √[3² + (- 12)²]

AC = 3√17

Third, add the three lengths to find the perimeter:

p = √146 + 5√5 + 3√17

p ≈ 35.633

The statement reports a typing mistake that it would take a triangle for an angle, which is absurd since angles only have one vertex. Correct statement is shown below:

Find the perimeter of Δ ABC to the nearest hundred, given the coordinates of its vertices A(x, y) = (- 3, 2), B(x, y) = (2, - 9) and C(x, y) = (0, - 10).

The image of ΔHOP with coordinates H(2,1), O(-3,4), and P(5,7).

(a) after 90° clockwise rotation is H'(1,-2,),O'(4,3),P'(7,-5) ,

(b) after 90° counterclockwise rotation is H''(-1,2),O''(-4,-3),P''(-7,5) ,

(c) after 180° rotation is H'''(-2,-1),O'''(3,-4),P'''(-5,-7) .

When a point (x,y) is rotated 90° in clockwise about the origin then the image after rotation becomes (y,-x) .

When a point (x,y) is rotated 90° in counterclockwise about the origin then the image after rotation becomes (-y,x) .

When a point (x,y) is rotated 180° about the origin then the image after rotation becomes (-x,-y) .

Part(a)

The ΔHOP with coordinates H(2, 1), O(-3, 4), and P(5, 7) is rotated 90° in clockwise direction ,

we know the points (x,y) becomes (y,-x),

So the image of ΔHOP after rotation becomes H' , O' , P'   .

H(2, 1) → H'(1,-2)

O(-3, 4) → O'(4,3)

P(5,7) →  P'(7,-5)

Part(b)

The ΔHOP with coordinates H(2, 1), O(-3, 4), and P(5, 7) is rotated 90° in counterclockwise direction ,

we know the points (x,y) becomes (-y,x),

So the image of ΔHOP after rotation becomes H'' , O'' , P''   .

H(2, 1) → H''(-1,2)

O(-3, 4) → O''(-4,-3)

P(5,7) →  P''(-7,5)

Part(c)

The ΔHOP with coordinates H(2, 1), O(-3, 4), and P(5, 7) is rotated 180°,

we know the points (x,y) becomes (-x,-y),

So the image of ΔHOP after rotation becomes H''' , O''' , P'''   .

H(2, 1) → H'''(-2,-1)

O(-3, 4) → O'''(3,-4)

P(5,7) →  P'''(-5,-7)

Therefore , The image of ΔHOP

(a) after 90° clockwise rotation is H'(1,-2,),O'(4,3),P'(7,-5) ,

(b) after 90° counterclockwise rotation is H''(-1,2),O''(-4,-3),P''(-7,5) ,

A triangle with two angles measuring 45⁰ and 92⁰ is an obtuse scalene triangle. The answer is A.

A triangle is a two-dimensional shape that has three sides and three angles. The sum of its interior angles is 180⁰.

If two angles of a triangle have measures 45⁰ and 92⁰, solving for the third angle

180⁰ = 45⁰ + 92⁰ + third angle

third angle = 43⁰

If a triangle has an angle greater than 90⁰, then it is an obtuse triangle.

If a triangle has angles less than 90⁰, then it is an acute triangle.

If a triangle has an angle equal to 90⁰, then it is a right triangle.

An isosceles triangle is a triangle with two congruent sides and congruent base angles (2 angles are equal).

An equilateral triangle is a triangle with all three sides equal and all three angles are of equal measures.

A scalene triangle is a triangle with no sides are equal and no angle are equal also.
