Answer:

5940 y

Step-by-step explanation:

Simplify the following:

-11 (-9)×5×3×4 y

-9×3 = -27:

-11×5×-27×4 y

-27×4 = -108:

-11×5×-108 y

-11×5 = -55:

-108-55 y

-55 (-108) = 5940:

Answer: 5940 y

Two jugs are similar. The smaller jug has radius 4cm and the bigger jug has radius
ivolga24 [154]

Given:

Two jugs are similar. The smaller jug has radius 4 cm and the bigger jug has radius 6 cm and surface area 125 cm².

To find:

The area of the smaller jug.

Solution:

If two figures are similar, then the ratio of their areas is proportional to the square of the corresponding sides of the figures.

Two jugs are similar. So,

\dfrac{\text{Area of smaller jug}}{\text{Area of bigger jug}}=\dfrac{(\text{Radius of smaller jug})^2}{(\text{Radius of bigger jug})^2}

\dfrac{\text{Area of smaller jug}}{125}=\dfrac{(4)^2}{(6)^2}

\dfrac{\text{Area of smaller jug}}{125}=\dfrac{16}{36}

\text{Area of smaller jug}=\dfrac{4}{9}\times 125

\text{Area of smaller jug}\approx 55.56

Therefore, the area of the smaller jug is about 55.56 cm².

I have two fair dice, each numbered 1 to 6. I add the two numbers together. What is the probability that I get a total of 5
Lostsunrise [7]

Answer:

Each dice has six combinations which are independent. Therefore the number of possible outcomes will be 6*6 = 36. The probability of rolling a pair of dice whose numbers add to 5 is 4/36 = 1/9.

Step-by-step explanation:

For the odds of these two numbers coming up at the same time, you multiply the odds of one times the odds of the other. 5/6 × 1/6 = 5/36. So the odds that you'll roll 2 dice total six are 5/36 each time you roll ( or approximately 1 chance in 7).
