Answer: can choose 1 of 3 entrees, 1 of 5 main courses and 1 of 2 desserts.
Step-by-step explanation:
She can choose entrees in 3 ways, the main course in 5 ways and dessert in 2 ways.
Now we just need to multiply these numbers so that we get all the possible combinations.
# of ways = 3 x 5 x 2 = 30
She can choose a three-course meal in 30 ways

Answer:
Hence, 12,90,000 can be expressed as 
.
Step-by-step explanation:
- Given 12,90,000
- Use given, move the decimal point so that first factor is greater than or equal to 1 but less than 10 .
- Then count n and write in scientific notation.
Step 1 of 1
Consider 12,90,000
1.29
So, 1.29 lies between 1 & 10.
Now, Decimal moved to 6 places at left.
So, 
.

Answer:
The numbers are 87 and 106
Step-by-step explanation:
x + y = 193
x - y = 19
Add y to both sides of the equation
x = 19 + y
Substitute new value for x into first equation
19 + y + y = 193
Add y's together
19 + 2y = 193
Subtract 19 from both sides of the equation
2y = 174
Divide both sides of the equation by 2
y = 87
193 - 87 = 106
The numbers are 87 and 106

Perpendicular is slope multiplies to -1
for
ax+by=c
slope=-a/b
4x-3y=6
-a/b=-4/-3=4/3
perpendicular to 4/3 is -3/4
point slope form
y-y1=m(x-x1)
for slope=m
a point is (x1,y1)
point (4,-2)
slope is -3/4
y-(-2)=-3/4(x-4)
y+2=-3/4(x-4)
or converted
y=-3/4x+1
or
3x+4y=4
