Answer:
12cm
Step-by-step explanation:
Width = 10 cm
Area = 120 cm²
Length = ?
Area = Length(L) × Width(W)
120cm² = L × 10cm
L = 120cm² ÷ 10 cm = 12cm
.6 x 10^-3 (Move the decimal in a multiple of 3 and don't forget it's 6 tenths not the whole number 6) In scientific notation this would be;
(the whole number)6 x 10^-4
"The quotient of a number and 3 less than twice the number" would translate to the expression x/(2x-3)
Basically we have x up top the fraction and 2x-3 in the bottom denominator of the fraction. The slash / means divide
Answer:
x = 14
Angle B = 121°
Angle C is 59°
Step-by-step explanation:
First we'll find x, then we'll find Angle B (by substituting in x), then we'll find Angle C (bc Angle B and C are supplementary--that us, they add up to 180°)
10x-19 = 7x+23 subtract 7x
3x-19 = 23 add 19
3x = 42 divide by 3
x = 14
Angle B is 10x-19, and if x=14, then its 10(14)-19
Angle B is 140-19
which is 121°
Angle B = 121°
Angle B and Angle C add up to 180°
121° + c = 180°
c = 180-121
Angle C is 59°
Hi there!
Find the volume of a sphere using the following equation:
V = 4/3πr³
Substitute in the given radius:
V = 4/3π(1)³
V = 4/3π or ≈ 4.19 units³
