65/500 = 13/100 = 13% of the flowers are roses.
Answer:
D
Step-by-step explanation:
in the question the scale factor is 4 so that means it is a dilation (getting larger) because the scale factor is >1
To solve this system of linear equations we need a little trick called elimination steps are below
we are given the following system of equations


if you look at the x variables in both equations you can see that we can easily eliminate them by multiplying the bottom equation by -4 as so


simplify and we get


now we can combine like terms on each side with the x's cancelling and get

now divide off -35

great now we can go back to our original system and pick a equation and substitute y back in to find x lets use

so now we substitute y and get




now we put x and y into one coordinate (x,y)
so now our FINAL ANSWER IS
(-17,-1)
Answer:
92
Step-by-step explanation:
x= the ideal mark for his third test
100 + 63 + x/3 = 85
163+x=85x3
163 + x = 255
x=92
He would need to get at least a 92 to have the 85 average.
Hello!
We must use a certain formula to find the circumference of a circle. The formula is:
C = 2 × pi × r
We have the diameter of the circle, so we'll be able to find its radius, since radius is always half the diameter.
r = d ÷ 2
r = 9 ÷ 2
r = 4.5
So, the radius of the circle is 4.5 centimetres. Pi equals approximately 3.14. Substitute:
C = 2 × 3.14 × 4.5
C = 6.28 × 4.5
C = 28.26
ANSWER:
The circumference of the circle is 28.26 centimetres long.
