Answer:

58°

Step-by-step explanation:

Good luck , hope it helped you :)

Answer:

58 degrees

Step-by-step explanation:

Since a straight line is 180 degrees then we can find out the two missing angles within the triangle.

180-126=54

180-112=68

54+68=122

180-122=58

m=58 degrees

Hope this helps :)

Answer:

Step-by-step explanation:

5 x (8 − 5) ÷ 3   5 times

5 x (8 − 5) ÷ 3   the difference of 8 and 5

5 x (8 − 5) ÷ 3   then divide by 3

5 times   the difference of 8 and 5   then divide by 3

Answer:

C. 10

Step-by-step explanation:

5+5=10

10+10=20

10+20=30

Answer:

The other is 10 yards long

Step-by-step explanation:

For a given rectangle

Perimeter (P) = 30 yards

and one of rectangle is 5 yards

Now,

Perimeter of rectangle

P = 2l + 2b

30 = 2(5) + 2b

30 = 10 + 2b

30 - 10 = 2b

20 = 2b

b = 20 ÷ 2

b = 10 yards

Thus, The other is 10 yards long

Answer:

86.33 square micrometers

Step-by-step explanation:

A silicon wafer is textured to minimize light reflection. This results in a surface made up of square pyramids. Each triangular face of one of the pyramids has a base of 5 micrometers and a height of 5.6 micrometers. Find the surface area of the pyramid, including the base.

The formula for the Surface Ares mma is given as :

A=a² + 2a √a²/4+ h²

a = base edge = 5 micro meters

h = height = 5.6 micro meters

=5²+2× 5 × √5²/4+ 5.6²

= 86.32699 square micrometers

≈ 86.33 square micrometers

Answer:

The given statement is true

Step-by-step explanation:

Complete question

As a result of aerobic respiration, the composition of the air that is breathed in and the air that is breathed out changes. Is this true

Solution

Yes the composition of gases inhaled and exhaled are of different composition.

We intake oxygen from atmosphere while breathing in. However, while breathing out we release carbon dioxide (CO2).

Hence the given statement is true.

You calculate wall-length like this.

Measure the length of each wall including doors and windows. Find the total square feet of the wall(s) by multiplying ceiling height by total wall length. Subtract areas that will not be covered.

Step-by-step explanation:

Answer: 4 and 1/2

Step-by-step explanation: Ok so 12 is a whole number so to turn it into a fraction put it over one as in 12/1.

Then just multiply 12/1 x 3/8 which equals 36/8 But we aren't done!

now we must calculate how many times 8 goes into 36 without going over 36 which is 4. 8 times 4 is 32 so we have 4 leftover. Now writing this as a fraction is 4   4/8. 4 is the whole number and that 4 represents 8 going tinto 36 4 times like we just demonstrated. since 36-32 is 4 thats how you get a 4/8 as your fraction.

Then you just simplify your fraction and 4  4/8 turns into just 4   1/2.

I really hope I explained this well and you understand it! :)

area of a circle = [tex]\pi r^{2}[/tex]

circumference =[tex]2\pi r[/tex]

Okay so the center of the circle is the same for both of the circles lets take that value as m so the radius of the inner circle is 54 - m

we have the circumference of the inner circle which is 270.04 we can find the value of m using that

[tex]270.04=2\pi (54-m)\\270.04= 339.2-6.28m \\6.28m = 339.2-270.04\\m= 11.02[/tex]

the radius of the inner circle is therefore 42.98

and the full circle has a radius off 65.02

area of shaded region = area of full circle - area of inner circle

area of shaded region = [tex]\pi (65.02)^{2} - \pi (42.98)^{2}[/tex]

area of shaded region = [tex]13281.39 - 5803.4[/tex]

area of shaded region = 7478 rounded off to the nearest whole number

Answer:

16

Step-by-step explanation:

In a 30 60 90 degree triangle, the hypotenuse is always double the shorter leg. Hope this helps! :)

The hypotenuse of the 30-60-90 triangle whose shorter leg is 8 m is: 16 m.

The 30-60-90 triangle is a right triangle whose hypotenuse length is always twice the length of the its shorter leg.

Given a 30-60-90 triangle whose shorter leg is 8 m long, therefore:

Hypotenuse of the 30-60-90 triangle = 2(length of the shorter leg)

Hypotenuse of the 30-60-90 triangle = 2(8)

Hypotenuse of the 30-60-90 triangle = 16 m.
