The answer using Pythagorean theorem

OverLord2011 [107]

Answer: 12.32 is the answer.

Step-by-step explanation: Using the pythagorean thereom we can solve this by using the formula A^2+B^2=C^2.

We substitute in the values,

17^2+B^2=21^2.

Now we simplify.

289+B^2=441

We subtract the 289 from both sides,

B^2=152

Now we use square root to find the answer.

12.32 is the answer.

Hope this helps!

Help me plz this is to much

Answer:

1 triangle: 2 m²
2 triangles: 4 m²
large rectangle: 32 m²
small rectangle: 3 m²
total area: 39 m²
cost of tile: $487.50

Step-by-step explanation:

You will run across many examples of poorly edited curriculum materials. This is one of them. We presume that every instance of "inches" should be an instance of "meters". The difference between in and m is not always obvious in a diagram, and m apparently got misinterpreted here.

The area of a triangle is given by the formula ...

A = 1/2bh

where b is the base and h is the height perpendicular to the base.

The triangles in this figure have a base of 4 m, and a height of 1 m. Using this formula, we find the area of 1 triangle to be ...

A = 1/2(4 m)(1 m) = 2 square meters . . . . area of 1 triangle

The triangles are the same size, so the area of both together is ...

2(2 m²) = 4 square meters . . . . area of both triangles together

The large rectangle is 8 m long and 4 m high. Its area is given by the formula ...

A = LW

where the length is L and the width is W. Using this formula, we find the area of the large rectangle to be ...

A = (8 m)(4 m) = 32 m² . . . . area of large rectangle

The small rectangle has a length of 3 m and a width of 1 m. Its area is ...

A = (3 m)(1 m) = 3 m² . . . . area of small rectangle

The total area is the sum of the areas of the pieces:

total area = 2 triangles + large rectangle + small rectangle

total area = 4 m² + 32 m² + 3 m² = 39 square meters

_____

At $12.50 per square meter, the cost of covering the patio is ...

($12.50/m²)(39 m²) = $487.50 . . . . cost of tile

Your medical research team is investigating the standard deviation of the cost of a 30-day-supply of a certain heart medication.

Valentin [98]

Considering the situation described, the hypothesis tested are given as follows:

The null hypothesis is $H_0: \sigma \geq 23$

The alternative hypothesis is $H_1: \sigma < 23$

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, it is tested if the standard deviation is not less than $23, that is:

$H_0: \sigma \geq 23$

At the alternative hypothesis, it is tested if there is significant evidence t conclude that the standard deviation is less than $23, that is:

$H_1: \sigma < 23$

Work out 3/5 of 900

Mars2501 [29]

Answer:

540

Step-by-step explanation:

1. We assume, that the number 900 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 900 is 100%, so we can write it down as 900=100%.

4. We know, that x is 3.5% of the output value, so we can write it down as x=3.5%.

5. Now we have two simple equations:

1) 900=100%

2) x=3.5%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

900/x=100%/3.5%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 3.5% of 900

900/x=100/3.5

(900/x)*x=(100/3.5)*x - we multiply both sides of the equation by x

900=28.571428571429*x - we divide both sides of the equation by (28.571428571429) to get x

900/28.571428571429=x

31.5=x

x=31.5

now we have:

3.5% of 900=31.5
