Answer:
25.2294 feet
Step-by-step explanation:
We can solve this question drawing a triangle using the values given and then using the law of sines. (See image attached to know how to draw the triangle and use the values).
First we need to find the third angle of the triangle, that is, the angle in the vertix where the bird is:
y + 55 + 63 = 180
y = 62°
The relation between the angles and the distances are:
25 / sin(y) = x / sin(63)
25 / 0.8829 = x / 0.8910
x = 25 * 0.8910 / 0.8829 = 25.2294 feet
Answer:
u probably need to just count the boxes. some are half so take it as 0.5
let the size of each box be 1 cm.
1) 14 cm or 14 unit (i m sure for this one)
2) it would approximately be 15 unit
my teacher taught me if the boxes are have different measurement other than half so just don't count that
u will fine your answers at the back of your textbook
Answer: The director can choose first a lead singer and then a stand-in for the lead singer in 132 ways.
Step-by-step explanation:
Given : The total number of singers auditioning for the school musical.= 12
The director wanted choose first a lead singer and then a stand-in for the lead singer.
We use Permutations here because order of selecting the singers matters.
The number of permutations of selecting r things out of n things =
Similarly , the number of ways to select 2 singers in an order from 12 singers
Hence, the director can choose first a lead singer and then a stand-in for the lead singer in 132 ways.
okkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk
Y= -3/2x
Because of rise over run so the rise is positive three and the run is negative 2 since it goes towards the negative direction
