Answer:

It is the letter A

Step-by-step explanation:

To find the perimeter you need to add all the sides. Since the width of the rectangle is 2 feet, you need to add it to another 2 since they have two equal sides. DO the same with 18 inches which is the length.

A room is 5m by 3m and has a height of 3.5m. Find the distance from a comer point on the floor to the opposite comer of the ceil

stiks02 [169]

Answer:

Approximately 6.8m

Step-by-step explanation:

We can picture this problem by drawing a rectangular prism with a width of 5m, a depth of 3m, and a height of 3.5m. To find the length from one corner of the floor to the opposite corner of the floor, we can use the pythagorean theorem and plug in the width and depth of the room for a and b:

$5^{2}+3^{2}=c^{2}$

And now we can solve for c...

$34 = c^{2}$

$\sqrt{34}=\sqrt{c^{2}}$

c = 5.831m

Now that we have the length from corner to corner across the floor, we can use the pythagorean theorem again, this time using the length from corner to corner across the floor we just derived and the height of the room:

$5.831^{2} + 3.5^{2}=c^{2}$

And now we can solve for c again...

$46.25=c^{2}\\\sqrt{46.25}=\sqrt{c^2}$

c = 6.8m

Thirty-six members of the middle school choir, which represents 30%, participated in the regional contents. How many total stude

Zina [86]

Answer:

120

Step-by-step explanation:

Given data

36 members are equivalent to 30%

Let the total number of students be x

Hence

30% of x= 36

30/100*x= 36

0.3x= 36

divide both sides by 0.3

x= 36/0.3

x= 120 students

Hence the total number of students is 120

What is the answer to this

stealth61 [152]

Hello!

The angle is a right angle, which measures 90°.

3x + x = 4x

Angle = 4x + 10 = 90

Switch that around

90 - 10 = 4x

90 - 10 = 80

80 = 4x

Divide by 4

$\frac{80}{4} = \frac{4x}{4}$ ]

$\framebox{x = 20 \°}$
