Add the veggieburger, soup, and cola prices together.
3.25 + 2.25 + 1.5 = x
Multiply by 0.04 to get the sales tax, then add the food cost to the tax.
0.04x + x = y
Multiply result by 0.15 to get the tip, then add the tip to the food cast and tax total.
0.15y + y = ?

If the sides of two similar triangles are in the ratio of 3:5, find the ratio of their areas.

Kazeer [188]

Ratio of areas of similar triangles is 9 : 25.

Solution:

Given data:

Ratio of sides of two similar triangles = 3 : 5

To find the ratio of areas of the triangles:

We know that,

In two triangles are similar, then the ratio of their area is equal to the square of the ratio of their sides.

$$\text{Ratio of areas} = \frac{\text{Area of triangle 1}}{\text{Area of triangle 2} }$

$$=\left(\frac{3}{5}\right) ^2$

$$=\frac{9}{25}$

Ratio of areas of similar triangles is 9 : 25.

A bag contains 6 red balls numbered 1, 2, 4, 5, 8, 9 and 4 white balls numbered 3, 6, 7, 10,

geniusboy [140]

Answer:

60%

a. 80%

b. 70%

Step-by-step explanation:

In this case we are first asked for the probability that when drawing a ball at random it is 8, 9 and 4 white balls numbered 3, 6, 7, 10, that is 6 balls. We know that there are a total of 10 balls since they are 6 red and 4 white, 6 + 4 = 10.

Therefore the probability is:

6/10 = 0.6

that is to say that the probability that it is one of these balls is 60%

to. that is red or odd,

red are 1, 2, 4, 5, 8, 9 and in addition to that, in white there is one with 3 and with 7 that are odd, making them 8 balls, therefore:

8/10 = 0.8

In other words, the probability is 80%

b. white or even,

the white ones are 3, 6, 7, 10 and in the red ones the 2, 4 and 8 are even, that is to say that they are 7 balls, which means that:

the probability is:

7/10 = 0.7

The probability is 70%
