Answer:

72°

Step-by-step explanation:

Hello There!

Complementary angles have a sum of 90 degrees

So to find the missing angle we subtract the measure of the given angle (18 in this case) from 90

90 - 18 = 72

so your answer will be 72°

Answer:

Step-by-step explanation:

hello :

r+b=7... (*)

3.75r+2.75b=22.25.... (**)

use (*) :  r = 7 - b

put this value in (**) :

3.75(7 - b)+2.75b =  22.25

26.25 -375b +2.75b = 22.5

-375b +2.75b = 22.5 - 26.25

- b = -3.75

so : b  = 3.75

but : r = 7 - b

r = 7 - 3.75

r = 3.25

Answer:

16

Step-by-step explanation:

because to get what you need add 27 and 28 and you get 55 then subtract 71 by 55 to get 16

71-(27+28)

Answer:

Grace sold 16 tickets.

Step-by-step explanation:

We have a total of 71 tickets sold between 3 people. Blake sold 27 tickets and Chang sold 28 tickets. Adding those sold by Blake and those sold by Chang, gives us: 27 + 28 = 55, if that amount is subtracted from the total sales that are 71 tickets, the result would be: 71 - 55 = 16, which would be the tickets sold by Grace.

Answer:

(1 cm)cos3πt

Step-by-step explanation:

Since the piston starts at its maximal height and returns to its maximal height three times evert 2 seconds, it is modelled by a cosine functions, since a cosine function starts at its maximum point. So, its height h = Acos2πft

where A = amplitude of the oscillation and f = frequency of oscillation and t = time of propagation of oscillation.

Now, since the piston rises in such a way that it returns to the maximal height three times every two seconds, its frequency, f = number of oscillations/time taken for oscillation where number of oscillations = 3 and time taken for oscillations  = 2 s

So, f = 3/2 s =1.5 /s = 1.5 Hz

Also, since the the piston moves between 3 cm and 5 cm, the distance between its maximum displacement(crest) of 5 cm and minimum displacement(trough) of 3 cm is H = 5 cm - 3 cm = 2 cm. So its amplitude, A = H/2 = 2 cm/2 = 1 cm

h = Acos2πft

= (1 cm)cos2π(1.5Hz)t

= (1 cm)cos3πt

Answer:

2 1/5+6 4/5 =  9

6 5/12 -2 1/12 = 4 1/3

11 8/9+4 1/3 =16  2/9

7 1/6-5 3/4 = 1  5/12

11/18+ 6 1/10 = 6 64/90

15 1/3- 2 5/8 = 12  17/24

Step-by-step explanation:

Using the technique of mixed numbers to add the fractions

2 1/5+6 4/5

=2+6 + 1/5+4/5     add the whole numbers separately and then the fractions

=8 5/5= 9

6 5/12 -2 1/12

=6-2 + 5-1/12

=4 4/12

= 4 1/3

11 8/9+4 1/3

=11+4 +8/9+1/3     adding the whole numbers separately

=15 + 8+3/9

= 15+11/9             adding the fractions separately

= 15+1+2/9

= 16+2/9

=16  2/9

7 1/6-5 3/4

= 7-5 +1/6 -3/4   subtracting the whole numbers separately

= 2+ 2-9/12   subtracting the fractions separately

= 2-7/12  

= 24-7/12

= 17/12

=1  5/12

11/18+ 6 1/10

= 11/18 + 61/10

= 110 +1098/180

= 1208/180

= 6 128/180

= 6 64/90

15 1/3- 2 5/8

=15- 2 + 1/3- 5/8

=13 + 8- 15/24

= 13 + -7/24

= 312-7/24

= 12 17/24

Answer:

n= -12

Step-by-step explanation:

- 2n/3  + 7=15          Subtract 7 from both sides and move all terms containing

           -7 = -7                      n to the right

- 2n/3 = 8                multiply both sides of equation by - 3/2

-3/2  x (-2n/3) = -3/2 x 8

n= -3/2 x 8                     cancel the common factor of 3

n= -12

Answer:

Answer:574.9ft^3.

Step-by-step explanation:

radius (r) = 6.5feet

π=3.14

volume of hemisphere=2/3 x π x r^3

Volume=2/3 x 3.14 x (6.5) ^3

Volume=2/3 x 3.14 x 6.5 x 6.5 x 6.5

Volume = (2x3.14x6.5x6.5x6.5) ➗ 3

Volume=1724.645 ➗ 3

Volume=574.9ft^3

The volume of a hemisphere with a radius of 6.5 ft, rounded to the

nearest tenth of a cubic foot is 574.9ft^3.

The volume of a hemisphere that has radius r can be calculated as

[tex]2/3\times \pi \times r^3[/tex]

It is given that the hemisphere

radius (r) = 6.5feet

π=3.14

The volume of a hemisphere

=[tex]= 2/3\times \pi \times r^3\\\\= 2/3 \times3.14\times (6.5) ^3\\\\2/3 \times3.14 \times6.5 \times6.5 \times6.5\\\\1724.645 /3\\574.9ft^3[/tex]
