What total length of ribbon is needed to Line the two long sides of the hat?
Answers
Answer:
Total length of ribbon to line the long sides will be 22 in
Step-by-step explanation:
In the given figure of kite if we draw a line "h" vertically will form two right angle triangles.
Then by applying Pythagoras theorem in both the triangles.
h²= (3x + 5)² + (2x + 1)² ------(1)
h²= (5x + 1)² + 5² ------(2)
By equating both the equations
(3x + 5)² + (2x + 1)² = (5x + 1)² + 25
9x² + 25 + 30x + 4x² + 4x + 1 = 25x² + 10x + 1 + 25
13x² + 34x + 26 = 25x² + 10x + 26
13x² - 25x² + 34x - 10x + 26 - 26 = 0
- 12x² + 24x = 0
12x² - 24x = 0
x² - 2x = 0
x(x - 2) = 0
x = 2
Now we will put x = 2 in the measure of sides of the kite.
Side 1 = (3x + 5)
= 3×2 + 5
= 11
Side 2 = (5x + 1)
= 5×2 + 1
= 11
Side 3 = (2x + 1)
= 2×2 + 1
= 5
Therefore, Total length of ribbon to line the long sides will be = 11 + 11
= 22 in.
Your answer will be D-22.

Final answer:
Para encontrar cuántos kilos de durazno compró Clara, debemos restar el peso de las manzanas y peras del peso total de la fruta que compró. Esto nos da que Clara compró 2.55 kilos de durazno.
Explanation:
Para calcular cuántos kilos de durazno compró Clara, primero debemos saber la cantidad de frutas que ya ha comprado. Sabemos que Clara compró 3/4 de kilo de manzanas y una libra de peras. En muchos lugares, una libra se considera 0,45 kilos, por lo que 1 libra de peras equivale a 0,45 kilos. Entonces sumamos estas dos cantidades, lo que equivale a 1.2 kilos (3/4 kilos + 0,45 kilos).
Ahora, si restamos este total (1.2 kilos) del peso total de la fruta que Clara compró (3 3/4 kilos o, lo que es lo mismo, 3.75 kilos), obtendremos el peso de los duraznos que compró Clara. Por lo tanto, 3.75 kilos - 1.2 kilos nos da 2.55 kilos.
Por lo tanto, Clara compró 2.55 kilos de durazno.

Distribute 1/3 into the parenthesis:
3x - 2 = 2x + 3
Subtract 2x to both sides:
x - 2 = 3
Add 2 to both sides:
x = 5
fist distirbute
a(b+c)=ab+ac
1/3(9x-6)=3x-2
3x-2=2x+3
subtract 2x from both sdies
x-2=3
add 2 to both sdies
x=5
