If the formula is V= Ab x H
then the base and height is 4 and 7.5 because it doesn’t need to be the bottom so you multiply 7.5 x 4= 30 but we have to half it since it’s a triangle which is 15 and then multiply 10 which gives us 150 cm squared.
2 hours 15 mins = 2 1/4 hours
2 1/4 hours = 25 miles
1 hour = 25 ÷ 2 1/4 = 25 ÷ 9/4 = 25 x 4/9 = 11.1 miles
Answer: 11.1 mph
Answer:
-(8 i + 1)
Step-by-step explanation:
Simplify the following:
5 - 3 i - (5 i + 6)
-(6 + 5 i) = -6 - 5 i:
-5 i - 6 + 5 - 3 i
-6 - 5 i + 5 - 3 i = (-5 i - 3 i) + (5 - 6) = -1 - 8 i:
-8 i - 1
Factor -1 from -8 i - 1:
Answer: -(8 i + 1)
The area of a circle is A=πr².
Since π is about 3.14 we can substitute that into the equation.
So A=3.14×r²
We can substitute the given radius for r.
A= 3.14 × 5²
When a number is squared, or has the two over it, we multiply it by itself.
5 × 5= 25
A= 3.14 × 25
Simplify this and the area of the circle is about 78.5
A≈78.5
1. s=6
2. z=16
3. t=2
4.n=98
5.r=-1.8
6.w=74/45
Hope these are correct
