Step-by-step explanation:
sales tax = total sales * tax rate
or I=PrT
s=(15.30)(.065)
s=.99
15.3+.99=16.29
First 6-10=-4
So then you get -4=9-X
Now you subtract 9 on both side
-4=9-X
-9. -9
----------
-13= -X
Now make the X positive basically get rid of the negative on both sides
x=13
Check by substituting in 13 for X
9-13= -4
6-10= -4
Answer:
5.75 cm²
Step-by-step explanation:
→ Utilise the area of a triangle formula
Area of a triangle = 0.5 × Base × Height
→ Identify base and height in the triangle
Base = 4.6 cm
Height = 2.5 cm
→ Substitute in the values into the area of a triangle formula
Area of a triangle = 0.5 × 4.6 × 2.5
→ Simplify
Area of a triangle = 5.75 cm²
The answer is probably the first or second one. I made it easier for you
Answer:
-16¹/₂ feet per second
Step-by-step explanation:
average change in altitude in feet per second = change in altitude in feet/change in time in seconds
= -41¹/₄ ft ÷ 2¹/₂ s
= -165/4 ft ÷ 5/2 s
= -165/4 × 2/5 ft/s
= -33/2 feet per second
= -16¹/₂ feet per second
