A factory makes 450 pies every day.
Gemiola [76]
Step by step:

Each day it takes a sample of 15 pies - on Monday he needed 4:

4/15 = x/450 (450 being the total for each day)

4 x 450 = 1800
1800 divided by 15 = 120

120 is the amount of pies that were made on Monday


Hope this helps

Hello brainly team I need help​
vova2212 [387]

Answer:

5)

x=13.856

y=8

6)

u=4

v=3.464

Step-by-step explanation:

5)

y=hypothesis * sin(opposing angle)/sin(angle opposite of hypothesis)

y = 16*sin(30)/sin(90)

y=8

x=hypothesis * sin(opposing angle)/sin(angle opposite of hypothesis)

x=16*sin(60)/sin(90)

x=13.856

6)

sinA/(opposite of angle A) = sinB/(opposite side of angle B) = sinC/(opposite of side of angle C)

sin(90)/u= sin(30)/2

u *sin(30) = 2* sin(90)

u *sin(30) = 2

u=2/sin(30)

u=2/0.5

u=4

sin(60)/v= sin(30)/2

v *sin(30) = 2* sin(60)

v *sin(30) = 2 * 0.866

v * sin(30) = 1.73

v = 1.73/sin(30)

v = 3.464

What are the solution(s) to the quadratic equation 9x2 = 4?
Lunna [17]
Multiply 9 by 2

18 = 4

Then subtract 4 from both sides

18 - 4 = 0 will become

14 = 0

Since 14 ≠ 0, there are no solutions
