Answer:
$6.21
Step-by-step explanation:
1 apple = $0.60
3 apples = $1.80 (Multiply 0.60 by 3)
2 bananas = $1.00 (Multiply 0.50 by 2)
1 quart of yoghurt = $4.50
Add the prices up first:
1.80 + 1.00 + 4.50 = $7.30
7.30 off 15% = $6.21
Answer:
csc theta = 25/7
Step-by-step explanation:
I believe you meant the Greek character theta, not 0. Note that sin 0 = 0, which is definitely not equal to 7/25.
Rewriting the given info, we obtain:
sin theta = 7/25 find csc theta
The csc function is the reciprocal of the sin function. Therefore,
if sin theta = 7/25, then csc theta = 25/7
Answer:
- 278.4°F
Step-by-step explanation:
Temperature of Object ( T ) = 1200° F
Temperature of surrounding ( M ) = 80°F
Time ( t ) = 1 hour
dT / dt ∝ ( M - T )
dT /dt ∝ | ( 80 - 1200 ) |
dT / dt = k ( 1120 )
(1200 - 830 ) / 1 = k ( 1120 )
hence k = ( 1200 - 830 ) / 1120
= 370 / 1120 = 0.33
<u>what is the object's temperature (x )after 4 hours </u>
( 1200 - x ) / 4 = 0.33 ( 1120 )
( 1200 - x ) / 4 = 369.6
hence x = 1200 - ( 4 * 369.6 )
= - 278.4 ° F
It 0.25 because if you put both together you get 2+2.5=4+2x then solve for x and you get x=0.25
