Answer:
Step-by-step explanation:
The line has a slope of -1/3. For lines to be perpendicular there product must equal negative 1
m1(m2)=-1
-m/3=-1
m=3
So we know our line has a slope of three so
y=3x+b, we can solve for the y intercept, b, using point (-2,8)
8=3(-2)+b
8=-6+b
b=14, so our line is
y=3x+14
Let one angle be x.
Other angle = x + 30°
Given, angles are complementary;
x + x + 30 = 90
2x = 60
x = 30°
Hence, the angles are 30° and 60°.
Answer:
4%
Step-by-step explanation:
The interest earned on the investment is the difference between the end-of-year value and the initial value:
$83.20 -80 = $3.20 . . . . simple interest per year
__
The interest rate is the ratio of this to the initial investment:
$3.20/$80.00 = 0.04 = 4% . . . . . simple interest rate per year
760,000 is the anwser since the number next to the 10000 place is 5. Round it up and its 760,000
Answer:
x=4
Step-by-step explanation:
The question shows an isoceles triangle, which means both sides should equal:
28=9x-8
36=9x
x=4
