Answer:
h = 16 unit
Step-by-step explanation:
The formular for the surface area of a triangular prism is given as,
A = ab+3bh............................ Equation 1
Where A = surface area of the triangular prism, a = height of the base triangle, b = base of the triangle, h = height of the box.
make h the subject of the equation
h = (A-ab)/3b........................ Equation 2
Given: A = 439.2, a = 6.9, b = 8
Substitute into equation 2
h = [439.2-(6.9*8)]/(3*8)
h = (439.2-55.2)/24
h = 16.
Hence the height of the box is 16 unit

Cynthia besch wants to buy a rug for a room that is 18ft wide and 35ft long she wants to leave a uniform strip of floor around rug she can afford to buy 528 ft of carpeting what dimensions should rug have
Answer:
rug long = 34 ft
rug wide = 17 ft
Step-by-step explanation:
given data
wide = 18 ft
long = 35 ft
area of carpet = 528 ft
solution
we get here area of floor that is
and we consider length of carpet = 35 - 2x
and width = 18 - 2x
(35 - 2x) × (18 - 2x) = 528 ...................1
solve it we get
x = 25.5 and x = 1
we choose 1 ft. as the width of the strip
so rug long = 35 - 1 = 34 ft
and rug wide = 18 - 1 = 17 ft

Answer:
Area = 7.853981 in^2 (2.5 Pi)
Perimeter = 11.42478 in (3.63Pi)
Step-by-step explanation:
Area
Lg semi circle area = Pi(2^2)(0.5) = 3.141593(4)0.5) = 6.283185 in^2
Sm semi circle area = Pi(1^2)(0.5) = 3.141593(2)(0.5) = 1.570796 in^2
added together = 7.853981 in^2
Perimeter
Lg semi circle perimeter = Pi(4)(0.5) + 2 = 8.283185 in
Sm semi circle perimeter = Pi(2)(0.5) = 3.141593 in
added together = 11.42478 in
if you get 0=0 is that no solution or IMS
looks like that would be ims

The x and y value from the given system of equations are 7 and -3 respectively.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
The given simultaneous equations are 3x-2y=27 ------(I) and 3x-y=24 ------(II) .
Subtract equation (I) from (II), we get
3x-y-(3x-2y)=24-27
⇒ y=-3
Substitute y=-3 in equation (I), we get
3x-2(-3)=27
⇒ 3x=21
⇒ x=7
Therefore, the x and y value from the given system of equations are 7 and -3 respectively.

Answer:
(-1,-3)
Step-by-step explanation:
Substitute y=x-2 into y=4x+1
x-2=4x+1
substract -1 on both sides.
x-3=4x
subtract x on both sides
-3=3x
divide by 3 on both sides
x=-1
Substitute -1 into equation
y=x-2
y=(-1)-2
y=-3
So it would be (-1,-3)

Is every rhombus with four right angles is a square. True or False
Answer:
True.
Step-by-step explanation:
A rhombus has four side of the same length (sometimes) and bisecting diagonals.
A square has what a rhombus has, as well as what a rectangle has.
A rectangle has parallel sides, four right angles, and congruent diagonals.
That means that a square has four right angles, four sides of the same length, and bisecting diagonals.
That's why a square is a rhombus and a rectangle but not its converse.
So, true.
Every rhombus with four right angles is a square. Therefore, the given statement is true.
What is a rhombus?A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square. Look at the image below to understand the relationship of rhombus shape with parallelogram and square.
A square is a quadrilateral with four equal sides. There are many objects around us that are in the shape of a square. Each square shape is identified by its equal sides and its interior angles that are equal to 90°.
Therefore, the given statement is true.

Si tengo $ 86 pesos y compro 3 libros de 1 ! " cada uno y seis objetos de a $ # " cada uno, ¿cuánto me queda? R = 77 $ " � %!& "
Answer:
Originalmente tenés $86 pesos.
Compras 3 libros de " 1 ! " cada uno.
(voy a suponer que 1 ! es un valor)
Entonces tenés que pagar 3 veces el valor 1 !
Esto significa que ahora tendrás:
$86 pesos - 3*(1 !)
Y ahora compras 6 objetos de $# cada uno.
Entonces tenés que pagar 6 veces $#.
Esto significa que tenemos que restar 6*$# a lo que te quedaba, entonces ahora vas a tener:
$86 - 3*(1 !) - 6*($#)
Este será tu resto después de la compra.
