Answer: verdadero.

Step-by-step explanation:

En geometría se dice que dos figuras son semejantes si tienen la misma forma pero no necesariamente el mismo tamaño.

Ahora, lo que define la forma de un triángulo son sus ángulos, entonces si dos triángulos tienen los mismos ángulos, estos triángulos van a tener la misma forma.

Y los lados siendo proporcionales entre ellos (recordar que una relación proporcional es y = k*x) habla de la relación entre los tamaños de los dos triángulos.

Entonces si, "dos triángulos son semejantes, si sus ángulos son iguales y sus lados proporcionales" es verdadero.

Rammy has $9.60 to spend on some peaches and a gallon of milk. Peaches cost $1.20 per pound, and a gallon of milk cost $3.60.

lesya692 [45]

Answer:

Rammy can buy 5 pounds of peaches

Step-by-step explanation:

1.20(5) + 3.60 = 9.60

subtract the cost of the gallon from the total amount and then divide the leftover cost $6 by $1.20 and you'll get 5.

In how many ways can we put five identical fruits into three bowls? Note that the bowls may be empty. The answer is not 243.

lord [1]

Answer:

6 ways

Step-by-step explanation:

The way to solve for this is to use the formula

Combination C (n-1, r-1)

= n = 5 identical fruits

r = 3 bowls

So, we have: 5 - 1 = 4

3 - 1 = 2

= 4!/2! (4-2)!

= 4 × 3 × 2 × 1/(2 × 1 )(2 × 1)

= 6 ways

1, 3, 6, 10, 15 is it arithmetic, geometric or neither

Gekata [30.6K]

The given sequence is neither arithmetic nor geometric.

Further explanation:

In order to check whether a sequence is geometric or arithmetic we have to find the common ratio and common difference respectively

Common difference is the deifference between cunsecutive terms of a sequence while common ratio is the ratio between two consecutive terms.

Common difference is denoted by d and common ratio is denoted by r

If the common difference is same then the given sequence is an arithmetic sequence
If the common ratio is same then the given sequence is a geometric sequence

Given

1, 3, 6, 10, 15

Common difference:

Here

$a_1=1\\a_2=3\\a_3=6\\a_4=10\\a_5=15\\Common\ Difference=a_2-a_1=3-1=2\\a_3-a_2=6-3=3\\a_4-a_3=10-6=4$

As the common difference is not same, the given sequence is not an arithmetic sequence

Common Ratio:

$r=\frac{a_2}{a_1}=\frac{3}{1}=3\\\frac{a_3}{a_2}=\frac{6}{3}=2\\\frac{a_4}{a_3}=\frac{10}{6}=1.6$

As the common ratio is also not same the sequence is not a geometric sequence.

The given sequence is neither arithmetic nor geometric.

The management of a supermarket wants to adopt a new promotional policy of giving a free gift to every customer who spends more

Vanyuwa [196]

The described situation represents a normal distribution.
For a normally distributed distribution, P(X < x) = P(z < (x - mean) / standard deviation))
P(x > 100) = 1 - P(z =< 100) = 1 - P(z < (100 - 80) / 12.12) = 1 - P(z < 1.6502) = 1 - 0.95055 = 0.04945 = 4.9%

Therefore, the required percentage of the customers expected to get free gifts is 4.9%.
