15. Considera um losango em que uma diagonal tem 8cm e cuja área é 12cm^2. Qual é o comprimento do lado do losango, arredondado às décimas? Nota: Indica apenas o valor numérico usando algarismos. (Não escrevas unidades de medida na resposta.)

Answers

Answer:

4,3cm

Step-by-step explanation:

Passo 1

Um losango tem 2 diagonais, cujos comprimentos não são iguais

Temos que encontrar o comprimento da segunda diagonal

A fórmula é dada como:

Área de um losango = 1/2 (d1 × d2)

Área do losango = 12 cm²

d1 = Comprimento da primeira diagonal = 8cm

d2 = Comprimento da segunda diagonal = x

12 = 1/2 (8 × x)

12 = 1/2 (8x)

12 = 4x

x = 12/4

x = 3cm

O comprimento da segunda diagonal = 3 cm

Passo 2

A fórmula do comprimento da lateral de um losango é dada como:

s = √d1² + d2² / 2

d1 = 8cm

d2 = 3 cm

s = √8² + 3² / 2

s = √64 + 9/2

s = √73 / 2

s = 8,5440037453 / 2

s = 4,2720018727 cm

Aproximadamente = 4,3 cm

Set up the following ratio which applies to all angle bisectors and the side opposite.

8 / (x + 4) = 12 / (2x + 1) Cross multiply

8 * (2x + 1) = 12 * (x + 4)

16x + 8 = 12x + 48 Subtract 8 from both sides

16x + 8 -8 = 12x + 48-8

16x = 12x + 40 Subtract 12x from both sides

16x - 12x = 40

4x = 40 Divide by 4

4x/4 = 40/4

x = 10

Rachel left home for school at 7:45 one morning. She returned home at 4:05 that afternoon. How many hours and minutes was she gone? (The number of minutes in your answer must be less than 60.)

Answers

Answer:

8 hours 20 minutes

Step-by-step explanation:

Given that :

Time Rachel left for school = 7:45 a.m

Time she returned Home = 4:05 p.m

Time for which Rachael was gone :

4:05 p.m - 7:45 a.m

7:45 a.m to 3:45 p.m= 8 hours

3:45pm to 4:05 pm = 20 minutes

= 8 hours 20 minutes

Rachael was gone for 8 hours 20 minutes

the mean of the ages of 5 brothers is 13 years. If the ages of four of the brothers are 12, 16, 14, and 8, how old is the fith brother

Answers

I don’t feel like solving it right now but in order to find a mean you have to add up all numbers and divide by the amount of people/objects.

If you want to solve this problem you would need to multiply 13 by 5 and then add 12, 16, 14, and 8 together and subtract it from your product of 13 and 5.

After that just check your answer by seeing if the mean of all the numbers is the same.

Mina tiene \dfrac{4}{5} 5 4 start fraction, 4, divided by, 5, end fraction de la harina necesaria para hacer una hogaza. Se necesita la misma cantidad de harina para hacer 111 hogaza que para hacer 121212 panes. ¿Cuál es el mayor número de panes que Mina puede hacer con la harina que tiene?

Answers

Answer:

El mayor número de panes que Mina puede hacer con la harina que tiene es 9 torrejas de pan.

Step-by-step explanation:

Una hogaza equivale a 12 torrejas de pan, si Mina tiene [tex]\frac{4}{5}[/tex] de la harina necesaria para preparar una hogaza. Entonces, el número total de torrejas es [tex]\frac{4}{5}[/tex] de 12 torrejas de pan. Es decir,

[tex]x = \frac{4}{5}\times 12[/tex]

[tex]x = 9.6[/tex]

Puesto que la cantidad de hogazas en un número entero, se trunca al entero más cercano. En consecuencia, el mayor número de panes que Mina puede hacer con la harina que tiene es 9 torrejas de pan.

The segments formed by the altitude to the hypotenuse of a right triangle are 8 and 10. Find the shorter leg of that triangle.

Answers

Answer: 6

Step-by-step explanation:

Since the hypothenuse is 10 and the larger leg of the triangle is given as 8, the shorter leg will be calculated as the square of the hypothenuse minus the square of the longer leg after which we find the square root of the value gotten. This will be:

Shorter leg² = 10² - 8²

Shorter leg² = 100 - 64

Shorter leg² = 36

Shorter leg = ✓36

Shorter leg = 6
