Answer:

2437.5m

Step-by-step explanation:

Assuming a rectangular shape, we have

Area=w×h, where w is the width anh h the length.

1km²=1000²m²=10⁶m²

7.8km²=7.8×10⁶=78×10⁵=3200×h

78×1000=32h

h=78000/32=2437.5m

A penny is tossed and a number cube is rolled. Find probability P(tails and 3). Please select one answer.

noname [10]

Answer:

the probability is 1/12

Step-by-step explanation:

The probability, P(Tails) to get tails is equal to:

$P(Tails)=\frac{1}{2}$

Because a penny have two possible options heads or tails and tails is one option.

Additionally, the probability P(3) that the number cube get a 3 is equal to:

$P(3)=\frac{1}{6}$

Because the cube have 6 possible options and 3 is one option.

Now, the probability P(tails and 3) is calculated as a multiplication of P(tails) and P(3). then, P(tails and 3) is equal to:

P(tails and 3) $=\frac{1}{2}*\frac{1}{6}=\frac{1}{12}$

Solve each inequality. Graph the solution on a number line.

Kamila [148]

Step-by-step explanation:

Step 1: Find the solution for the first one

$4x > -36$

$4x / 4 > -36 / 4$

$x > -9$ ← Solution

Step 2: Find the solution for the second one

$7u\le-49$

$7y/7\le-49/7$

$y \le -7$ ← Solution

Step 3: Find the solution for the third one

$-5m \ge 15$

$-5m / -5 \ge 15 / -5$

$m \le -3$ ← Solution

Step 4: Find the solution for the fourth one

$-2p > -3$

$-2p / -2 > -3 / -2$

$p < 1.5$ ← Solution

Step 5: Find the solution for the fifth one

$45 \le - 10r$

$45 / -10 \le -10r / -10$

$-4.5 \ge r$ ← Solution

Step 6: Find the solution for the sixth one

$-66 \ge -11t$

$-66 / -11 \ge -11t / -11$

$6 \le t$ ← Solution
