Answer:
Ned lost 16 points total.
Step-by-step explanation:
If Ned got 6 questions wrong, and each one cost him four points, that would be 24 points total. 6x4=24. But since Ned got 8 additional points on a bonus question. It equals out to a total los of 18 points.
-24 + 8= -16
Multiply 2/3 by 3/8:
(2*3/3*8 = 2/8 = 1/4)
Jennifer ate a quarter pound of berries.
Answer:
$176.3193692 or $176.32 (rounded to two decimal places)
Step-by-step explanation:
It is a compound interest, which means the interest accumulates on an initial amount each period.
The formula is A=P(1+R)^n
A= the total amount P=initial amount R=rate n=time (years)
P=$120 Rate= 8% or 0.08 (decimal) n=5 (years)
A=120 (1+0.08)^2
A=120 (1.469328077)
A= 176.3193692
Add 1 to both sides of the equation to get 4x = 4.
Divide both sides by 4 and <em>x = 1</em>.
Answer:
y = (7/2)x -20
Step-by-step explanation:
The given line is in slope-intercept form, so you can read its slope from the equation.
y = mx + b . . . . . m is the slope; b is the y-intercept
y = -(2/7)x + 9 . . . . . . has slope -2/7
The perpendicular line will have a slope that is the negative reciprocal of this, so will be ...
m = -1/(-2/7) = 7/2
We can use this and the given point to write the equation in point-slope form.
y = m(x -h) +k . . . . . . line with slope m through point (h, k)
We have m = 7/2, (h, k) = (4, -6) so the equation is ...
y = (7/2)(x -4) -6
y = (7/2)x -20
