The formula is base x height
Answer: You need a grade of 78 on the final exam to earn a final grade average of at least 87 in each grading system.
Step-by-step explanation:
(85 + 90 + 95 + x)÷ 4 =87
Simplify:
(270 + x) ÷ 4 = 87
Rearrange:
(x + 270) ÷ 4 = 87
Multiply terms to Reduce:
4((x + 270) ÷ 4) = 4 * 87
Cancel Multiplied terms in Denominator:
x + 270 = 4 * 87
Multiply:
x + 270 = 348
Subtract 270 on both sides of the equation:
x + 270 - 270 = 348 - 270
Simplify:
x = 78
Cow : 9 x 10^2 = 9 * 100 = 900
whale : 1.8 x 10^5 = 1.8 * 100,000 = 180,000
180,000/900 = 200
The blue whale has about 200 times more mass <==
The equation is y=(-1/2)x +2
Answer:
A=1
B=6
C=5
Step-by-step explanation:
0=ax²+bx+c
0= 1x²+6x+5
There is no number in front of x², so you know the coefficient is 1.
The coefficient in front of the x is 6.
The remaining number is 5.
