you generate 3 random whole numbers from 1 to 10. Is it unlikely or even impossible that all the numbers could be 10?

It is unlikely but possible to generate the same number 3 times because each number has the same probability of being generated at random.
hope this was helpful.

How tall is a tree which is 15 feet shorter than a pole that is 3 times as tall as the tree?

Citrus2011 [14]

<h2>Height of tree is 7.5 feet</h2>

Step-by-step explanation:

Let t be the height of pole.

Given that the tree is 5 feet shorter than a pole.

Height of pole = t + 15

Also given that the pole is 3 times as tall as the tree.

Height of pole = 3t

So we have

t + 15 = 3t

2t = 15

t = 7.5 feet

Height of tree = 7.5 feet

The spinner of the compass is two congruent isosceles triangles connected by their bases as shown in the diagram. The base of ea

a_sh-v [17]

Answer:

fff

Step-by-step explanation:

By pythagorean theorum we calculate the height:

$\sqrt{5^2-1^2}$

= $\sqrt{24}$ = height of triangle

area of triangle = base * height

area = $2*\sqrt{24}$

There are two triangles so:

$2*2*\sqrt{24}=4\sqrt{24}$

Multiply this by 13.25 to get total cost:

=$259.65

Easy math for smart people problem: 5(2d+4)=35

Likurg_2 [28]

Answer:

3/2 (decimals): 1.5

Step-by-step explanation:

1. 5(2d+4)=35 -> multiply 5 to (2d+4)

2. 10d + 20 = 35

3. Subtract 20 by both sides

10d = 35-20

10d = 15

4. divide 10 by both sides

d = 15/10

d = 3/2
