Answer:
x = 2root(22)
see image.
Step-by-step explanation:
The triangle shown is one big triangle cut into two more smaller triangles: one medium-sized and one smaller.
ALL THREE TRIANGLES ARE SIMILAR BY AA.
Set the two smaller triangles up so you can see the corresponding sides. x is the short leg in one triangle and it is the long leg in the smallest triangle. Set up a proportion.
22/x = x/4
crossmultiply
x^2 = 22•4
x^2 = 88
square root both sides.
x = sqroot(88)
x = 2sqroot(22)
see image.
Answer a is 14.40 the discount price is 14.40
Answer:
is the solution set.
Step-by-step explanation:
Divide eqn(2) by 3.
Hence both are the same lines.
if where be any point on real line iR.
from eqn (1)
Hence solution set is
Answer:
6/25, or 0.24
Step-by-step explanation:
There are 25 numbers from which to choose, each equally likely to be chosen.
Multiples of 4 that are between 1 and 25 are {4, 8, 12, 16, 20, 24}
There are 6 such multiples of 4, out of 25 numbers total.
Thus, the probability of choosing a number from 1-25 that is a multiple of 4 is 6/25, or 0.24.
Answer:
19
Step-by-step explanation:
The pattern is that it +6 every number.
-5 + 6 = 1
1 + 6 = 7
7 + 6 = 13
So the next number is 13 + 6 = 19.
