The measure of the obtuse angle marked UVW is 108

Step-by-step explanation:

Here, we want to get the measure of the angle marked UVW

To get this, we refer to the given diagram

From the diagram;

UVW = UVX + XVW

UVW = 68 + 40

UVW = 108 degrees

Answer:

A quadrilateral has a parallelogram if one pair of opposite sides is congruent and parallel. Parallelograms are designed to have diagonals that bisect one another. When ABCD is bisected by — BD and —AC, then ABCD is a parallelogram.

Step-by-step explanation:

Answer:

A quadrilateral has a parallelogram if one pair of opposite sides is  coinciding exactly when superimposed and parallel. Parallelograms are designed to have diagonals that bisect one another. When abcd is bisected by  bd and ac, then abcd is a parallelogram.

Answer:

45000 m

Step-by-step explanation:

Speed = distance / time

10 km/h = distance / 4.5 hours

distance = 10 x 4.5 = 45 km

Kilometre needs to be converted to metres

Ikm = 1000m

45 x 1000 = 45,000m

Step-by-step explanation:

Diagonals of a parallelogram bisects each other.

Therefore,

4x = 8

x = 8/4

x = 2

Or

5x = 3x + 4

5x - 3x = 4

2x = 4

x = 4/2

x = 2

Answer:

69

Step-by-step explanation:

Answer:

69 m²

Step-by-step explanation:

The figure is composed of 2 right triangles

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

A of triangle on left is

A = [tex]\frac{1}{2}[/tex] × 9 × 10 = 45 m²

A of triangle on right is

A = [tex]\frac{1}{2}[/tex] × 8 × 6 = 24 m²

Total area = 45 + 24 = 69 m²

Answer:

Only those members of the marketing team eating together at the picnic

Step-by-step explanation:

The members of the marketing team eating together at the picnic weren't randomly selected from a larger population. They may not be representative of employees (marketing team or not) beyond their group.

Only members of the marketing team eating together depicts a 80 percent legitimate estimate of the percent of employees who like the new slogan.

This can be defined as the approximate calculation of a set of data or values.

The members of the marketing team eating together will represent 80 percent legitimate estimate because they weren't randomly selected from a larger population.

Answer:

x²+2x+3

Step-by-step explanation:

We are to simplify the expression;

5x³+10x²+15x/5x

Factor out 5x from the numerator

= 5x(x²+2x+3)/5x

5x will cancel out both at the top and bottom to have;

x²+2x+3

Factorize

x²+2x+3

Hence the simplified form is x²+2x+3

Answer:

y = 841.25 feet

Step-by-step explanation:

Given that,

The height of the rocket, y in feet, is  related to the time after launch, x in seconds, by the given equation as follows:

[tex]y = -16x^2 + 212x + 139[/tex] ....(1)

We need to find the maximum height reached by the rocket.

For maximum height, put dy/dx = 0

So,

[tex]\dfrac{d(-16x^2 + 212x + 139)}{dx}=0\\\\-32x+212=0\\\\x=\dfrac{212}{32}\\\\x=6.625\ s[/tex]

Pu x = 6.625 in equation (1).

[tex]y = -16(6.625)^2 + 212(6.625) + 139\\\\y=841.25\ feet[/tex]

So, the maximum height reached by the rocket is equal to 841.25 feet.

Pregunta completa:

Un albañil pone azulejos a una pared de 6 m de largo y 2,4 m de alto. Los azulejos son cuadrados de 30 cm de lado. ¿Cuants, cajas tendra que comprar si en una caja hay 25 azulejos? Con procedimiento.

Respuesta:

160 tejas

7 cajas

Explicación paso a paso:

Dimensión de la pared = 6 m por 2,4 m

Área de la pared = 6 m * 2,4 m

Área de la pared = 14,4 m²

Longitud lateral, s de teja cuadrada = 30 cm = 0,3 m

Área de la loseta cuadrada = s² = 0.3² = 0.09m²

Número de baldosas cuadradas necesarias:

14,4 m² ÷ 0,09 m²

= 160 fichas cuadradas

Si hay 25 fichas en una caja;

Número de cajas a comprar:

160/25

= 6,4 ≈ 7 cajas

Answer:

I think it's 160 square inches. Try L x W x H (length multiplied by width multiplied by height). So that would mean 4 x 5 = 20 x 8 = 160,

Answer:

b = -9

Step-by-step explanation:

Given the equation (−34 + 43)+ b = 0

We are to find the value of b

First solve for the value in parenthesis

(−34 + 43)+ b = 0

9+b = 0

Subtract 9  from both sides

9+b-9 = 0 - 9

b+0 = -9

b = -9

Hence the value of b will make the equation a true statement is -9
