Formula = b*h / 2

base = 15 + 6 =21
height = 8

21 * 8 = 168

168/2 = 84

The area is 84 in.

Hope this helped☺☺

Area of triangle = 1/2 x base x height

base = 15 + 6 = 21
height = 8

Area of triangle = 1/2 x 21 x 8 = 84 in²

Answer:

The greatest number of arrangements that he can make if every balloon is used is 8.

Step-by-step explanation:

The greatest number of arrangements will be the greatest common factor between 24 and 32.

GCF of 24 and 32:

We keep factoring both numbers by prime factors, while they can both be divided by the same number. So

24 - 32|2

12 - 16|2

6 - 8|2

3 - 4

There is no factor for which we can divide both 3 and 4. So the GCF is 2*2*2 = 8.

This means that the greatest number of arrangements that he can make if every balloon is used is 8.

1. What is the mean to the nearest tenth?

Inessa [10]

Solution: 1. The mean is given below:

$Mean=\frac{\sum fx}{\sum f}$

Where:

$f$ is the frequency

$x$ is the value

$\therefore Mean=\frac{1 \times 7 + 2 \times 1+ 3 \times 3 + 4 \times 2 + 5\times 2}{15}$

$=\frac{7+2+9+8+10}{15} =\frac{36}{15} =2.4$

Therefore, the mean = 2.4

2. The mean is given below:

$Mean = \frac{8+11+23+15}{4}$

$=\frac{57}{4}$

$=14.3$

I am not understanding why your teacher 14.3 is wrong. Please check whether the weight of 4 pumpkins is correct or not.

3. We are given that on average 5 passengers will board the bus at each of the 6 stops.

Let x be the number of passengers board the bus at the sixth stop.

Therefore, the average is:

$\frac{3+7+5+6+2+x}{6} =5$

$23+x=30$

$x=30-23$

$x=7$

Therefore, 7 passengers need to board the bus at the sixth stop for Leah's prediction to be true.
