Answer:
50 ?
Step-by-step explanation:
You didn't give any detail about how many beads it takes to make one bracelet
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
t = 9 / ( 450 × 0.04 ) = 0.5
t = 0.5 years
The time required to
accumulate simple interest of $ 9.00
from a principal of $ 450.00
at an interest rate of 4% per year
<span>is 0.5 years (about 0 years 6 months).</span>
Answer:
The 3 angles are 62 2/3, 44 2/.3 and 72 2/3 degrees.
Step-by-step explanation:
let x be the first angle then the the second angle is x - 18 and the third angle = x + 10
The 3 angles add up to 180 so:
x + x - 18 + x + 10 = 180
3x = 180 + 18 - 10 = 188
x = 188/3 = 62 2/3 degrees.
x - 18 = 44 2/3
x + 10 = 72 2/3.

You only follow the letters as their order
In first triangle, so VX = MK
Answer:
0.50 seconds
Step-by-step explanation:
The time it takes for an echo to return is the time it takes for the sound to make the round trip between the source and the reflecting object.
The boulder is 80 m away from the source, so the round-trip distance is 2×80 m = 160 m. At a speed of 320 m/s, it takes sound ...
(160 m)/(320 m/s) = 0.50 s
to make the round-trip.
It will take 0.50 seconds to hear the echo.
