Answer:

31.4

Step-by-step explanation:

To find circumference, the formula is A=pi*r^2. The radius is 1/2 the diameter. The radius of the donut is 3.5. 3.5^2 is 12.25. Pi is approximately 3.14, so 12.25*3.14 is 38.465. The donut hole takes away from the circumference, so we have to subtract the circumference of the donut hole from the donut. 1.5^2 is 2.25, and 2.25*3.14 is 7.065. 38.465-7.065 is 31.4. The circumference of the circle is 31.4.

Answer: 480 sq ft

Step-by-step explanation:

for two rectangles on right do 8*16 =128*2 = 256

the rectangle on the right is also 128

total of all rectangles is 384 ft

now for the triangles

formula: 1/2 b*h

1/2 * 16*6 = 48

multiply that by 2 for both triangles

you have 96

add that to total and you get

480 sq ft

Answer:

Step-by-step explanation:

The hypotenuse of the triangles is the length of the rectangles so the length of the rectangles is 16 ft. The width of the rectangles is 8 ft. There are 3 rectangles so the surface area of them is:

(16*8)*3 = 384[tex]ft^{2}[/tex]

The area of a triangle is base times height divided by two. Here, the height of the two triangles is 6 ft and the base is 16 ft. So, the area of the two triangles is:

[tex]\frac{6*16*2}{2}[/tex] = 16*6 = 96  [tex]ft^2[/tex]

Add the two areas together to get the surface area.

384[tex]ft^2[/tex] + 96[tex]ft^2\\[/tex] = 480[tex]ft^2[/tex]

Hence, the surface area of the triangular prism is 480[tex]ft^2[/tex]

Answer:

first is 1/8, second is 1/10, third is 1/15, and fourth is 1/16

Step-by-step explanation:

1/2 divided by 4 = .5/4

.5/4 = 0.125

.125 = 1/8

1. 1/8

1/5 = .2

.2/2 = .1

.1 = 1/10

2. 1/10

since 1/3 would be a repeating term, you can change 5 to 5/1

3/1 = 3

1/5 = .2

.2/3 = 1/15

3. 1/15

1/4 divided by four = 1/4 divided by 1/4

1 x 1 = 1

4 x 4 = 16

4. 1/16

Answer:

Pythagoras

Step-by-step explanation:

To figure out how old each philospher was, we can find the difference between their birth and death years.

For Aristotle: 384 - 322 = 62 years old

For Pythagoras: 580 - 495 = 85 years old

For Plato: 428 - 348 = 80

85 > 80 > 62

So, Pythagoras lived the longest out of these three Greek philosophers.

Given :

48°

90°{boxed like shape}

{sum of angles of triangle}

~Tulpe⚘

Answer:

x = 42°

Step-by-step explanation:

Given that,

→ A = 48°

→ B = 90°

→ C = x

Formula we use,

→ A + B + C = 180°

Let's solve for the value of missing angle,

→ A + B + C = 180°

→ 48° + 90° + x = 180°

→ 138° + x = 180°

→ x = 180° - 138°

→ [ x = 42° ]

Hence, value of missing angle is 42°.

The balance point, or average value of those numbers, would be 4.75 or 4 and 3/4

Answer:

tan (A) = 1

Step-by-step explanation:

When sine and cosine are equal to each other, they have the same value. We know that tan (A) = sin (A) / cos (A). If sin (A) and cos (A) are the same, and any number divided by itself equals 1, the final answer must be tan (A) = 1.

The angle the 14 foot long wire must make with the gound is approximately 51 degrees.

A right angle triangle is a triangle that has one of its sides as 90 degrees. The situation forms two right angle triangle.

Using cosine law,

17² = 14² + 22² - 2 × 14 × 22 cos C

289 - 196 - 484 = -616 cos C

-391 = -616 cos C

divide both sides by -616

cos C = -391  / -616

cos C = 0.63474025974

C = cos⁻¹ 0.63474025974

C = 50.59929658

C = 51 degrees.

Therefore, the angle the 14 foot long wire must make with the gound is approximately 51 degrees.

As per the  Intersecting Chords theorem, if two chords cross in a circle, the products of the chord segments' measures are equal. The measure of the line segment is DF is 14 units.

If two chords cross in a circle, the products of the chord segments' measures are equal.

As per the Intersecting Chords theorem, the product of DF and FB will be equal to the product of CF and FA, therefore,

DF×FB = CF×FA

(x+8) × 8 = 16 × 7

(x+8) = (16×7)/8

(x+8) = 14

Hence, the measure of the line segment is DF is 14 units.

Answer:

0.8 or 8/10

Step-by-step explanation:

1/10 can be converted to decimal form as 0.1.

70/100 can be converted to decimal form as 0.7

0.1 + 0.7 = 0.8

Another way is making use of a common denominator:

Common denominator --> 100

1/10 --> mutiply numerator and denominator by 10 --> 10/100

10/100 +70/100 = 80/100 = 8/10 = 0.8
