Answer:
a quadrilateral with 2 right angles could be a trapezoid so balavan is wrong. because if 3 angles are right angles the the fourth angle might also be a right angle and has to be a square or rectangle so denna is right
Step-by-step explanation:
Answer:
The sum of the angles in a quadrilateral is 360°, and a rectangle or square has four 90° angles.
A quadrilateral can be formed with two right angles and two angles that are other measures.
If three angles are 90°, the total is 270°, so the fourth angle is 90°.

Si al doble de la edad de
Juan le sumas 8, obtienes
32.
¿Cuál es la edad de Juan?
Answer:
Step-by-step explanation:
No se si esto deberia ser mas dificil pero aqui voy:
Pregunta 1.
27 - 15 = 12
El numero es 12
Pregunta 2.
27 - 5= 22 dividido 2 = 11
El numero que pensastes es 11
Pregunta 3.
32 - 8 = 24 dividido 2 = 12
El tiene 12 años
Use el metedo reversa.
Construyendo y resolviendo las ecuaciones, encontramos que:
1. El numero es 12.2. El numero es 11.3. La edad de Juan es 12.---------------
Ejercicio 1
El número es x.Sumando 15, tenemos x + 15 Obtuve 27, entonces:[tex]x + 15 = 27[/tex]
[tex]x = 27 - 15 = 12[/tex]
El numero es 12.---------------
Ejercicio 2
El número es x.Multiplicando por 2, tenemos 2x. Sumando 5, tenemos 2x + 5.Obtuve 27, entonces:[tex]2x + 5 = 27[/tex]
[tex]2x = 22[/tex]
[tex]x = \frac{22}{2}[/tex]
[tex]x = 11[/tex]
El numero es 11.---------------
Ejercicio 3
La edad es x.Doble de la edad es 2x.Sumando 8, tenemos 2x + 8.Obtuve 32, entonces:[tex]2x + 8 = 32[/tex]
[tex]2x = 24[/tex]
[tex]x = \frac{24}{2}[/tex]
[tex]x = 12[/tex]

Find the value of x if the measure of angle 1 = 11x - 9 and the measure of angle 5 = 7x + 9
Answer:
x = 10
Step-by-step explanation:
Lett angle 1 and angle 5 lie on the same straight line. This shows that they are supplementary
Hence;
<1 + <5 = 180
11x - 9 + 7x + 9 = 180
18x = 180
x = 180/18
x = 10
Hence the value of x is 10
The diameter of a planet is about 25,660 mi. The diameter of the planet's moon is about 35% of the diameter of the planet. What percent of the volume of the planet is the volume of its moon?
The volume of the planet's moon is % of the volume of its planet.
(Round to the nearest whole number as needed.)
Answer:
4%
Step-by-step explanation:
Volume of sphere
v = (4/3)πr^3
Volume moon/ volume planet
We don't actually need the numeric value of the radius
just the 35% ratio
Radius of moon = .35 radius of planet
Vm/ Vp = (4/3)π(.35r)^3 / (4/3)π(r)^3
Cancel like terms
Vm / Vp = .35^3
Vm / Vp = 0.042875
Expressed as a percentage
Vm / Vp = 4.2875%
Rounded
Vm / Vp = 4%

what is the product of 3.4* 10^2 and 1.8* 10^3 expressed in scientific notation
Answer:
6.12 x 10⁵
Step-by-step explanation:
You just multiply 3.4 and 1.8 which gives 6.12
And for the notation you add the exponents 2 and 3 which give 5
Answer:
6.12 × 10^5.
Step-by-step explanation:
3.4 × 10² × 1.8 × 10³
To solve this, we can group.
[tex](3.4 * 1.8) * (10^2 * 10^3) =[/tex] [tex](6.12) *(10^5).[/tex]
Therefore,[tex](3.4 *1.8)*(10^2*10^3) = 6.12 * 10^5[/tex]
