Find the area of the triangle with the given base and height. b = 3 m and h = 10 1/2 m

svetoff [14.1K]

Statement:

The base of a triangle is 3m and its height is $10 \frac{1}{2}$ m.

To find out:

The area of the triangle.

Solution:

Given, base = 3m, height = $10 \frac{1}{2}$ m
We know,

$\sf \: area \: \: of \: \: a \: \: triangle = \frac{1}{2} \times base \: \times height$

Therefore, the area of the triangle

$\sf = (\frac{1}{2} \times 3 \times 10 \frac{1}{2} ) {m}^{2} \\ \sf = ( \frac{1}{2} \times 3 \times \frac{21}{2} ) {m}^{2} \\ = \sf \frac{63}{4} {m}^{2} \\ = \sf 15\frac{3}{4} {m}^{2}$

Answer:

The area of the triangle is $\sf \: 15 \frac{3}{4} {m}^{2}$

Hope you could understand.

There are 24 people using a gun. the ratio of men to women is 2 : 1. how many men are using the gym

Arada [10]

The number of men using the gun is 8, using the given ratio of men to women as 2:1.

In the question, we are given that the ratio of men to women using a gun is 2:1, and a total of 24 people use a gun.

We are asked to find the number of men using the gun.

By the given ratio, we take the number of men using a gun to be 2x, whereas the number of women using a gun is x.

Thus, the total number of people using the gun = the number of men using a gun + the number of women using the gun,

or, the total number of people using the gun = 2x + x = 3x.

But, the total number of people using the gun is given to be 24.

Thus, we get an equation 3x = 24.

On solving this, we get:

3x = 24,

or, 3x/3 = 24/3,

or, x = 8.

Now, the number of men using a gun = 2x = 2*8 = 16.

The number of women using a gun = x = 8.

Thus, the number of men using the gun is 8, using the given ratio of men to women as 2:1.

A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a storm is in progress wit

shtirl [24]

Answer:

The alternate hypothesis is:

$H_{a} < 16$

Step-by-step explanation:

There are two types of hypothesis. The null hypothesis and the alternate hypothesis. The null hypothesis is that the mean found is equal to the expected value. The alternate hypothesis is a question about this expected value(different, more, less)

A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore.

This means that the null hypothesis is $H_{0} = 16.4$

Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis

Dying down means lower average peak, that is, lower than the average of 16.4. This means that the alternate hypothesis is:

$H_{a} < 16$
