Answer:
Step-by-step explanation:
4 x 10^7 is 40000000
4 x 10^3 is 4000
We are told that 4x10^7 is something times as much as 4x10^3
So we will work backwards to find the answer,
If you divide 40000000 by 4000 you will get 10000
10000 is the same as 10^4
Solution:
<u>We know that:</u>
- Radius: 18 yards
- πr² = Area of circle
- π = 3.14
<u>Finding the area of the circle:</u>
- (π)(r²) = Area of circle
- => (3.14)(18²) = Area of circle
- => (3.14)(324) = Area of circle
- => Area of circle = 3.14 x 324 = 1017.36 yards²
Answer:
carnation $2.50; rose $3.00
Step-by-step explanation:
Let c = price of 1 carnation.
Let r = price of 1 rose.
3c + 5r = 22.5
3c + 2r = 13.50
Subtract the se3cond equation from the first equation.
3r = 9
r = 3
Now substitute r = 3 in the first equation and solve for c.
3c + 5r = 22.5
3c + 5(3) = 22.5
3c = 7.5
c = 2.5
Answer: carnation $2.50; rose $3.00
Equation parallel to y = -x is y=-x+k
so 4.5 = -7 + k so k - 11.5
Equation is y = -x + 11.5
