Raise the unit selling price .25 cents from $2.50 to $2.75
Answer:
n = - 30
Step-by-step explanation:
Eight plus the quotient of a number and 3 is −2
Expressing in mathematical terms, we have;
8 + (n/3) = -2
To solve for n;
Multiply all through by 3.
3*8 + 3(n/3) = 3 * (-2 )
24 + n = - 6
n = -6 - 24
n = - 30
Answer:
c = 4.79 feet
Step-by-step explanation:
Given question is incomplete without a picture; find the question with the attachment.
Two poles AD and DB of same length are leaning against each other.
Distance between the poles (AB) = 45 feet
m(∠ADB) = 180°- (60 + 50)°
= 70°
By sine rule,
= 36.68 ft
Similarly,
DB = 
= 41.47 ft
Now c = DB - AD
= 41.47 - 36.68
= 4.79 feet
Answer:
R = 4cm
Step-by-step explanation:
V = π(R)²h = 480π
Divide by π
(R)²h = 480
Substitute h with 30
30*(R)² = 480
Divide by 30
(R)² = 16
Square root
R = 4cm
We do not accept R= -4 because it's a length, so it must be positive.
