She needs 8 daisies.
1 arrangement = 10 flowers = 2/10 are daisies.
4 * 10 = 40 flowers
2/10 * 40 = 80 / 10 = 8 daisies.
4 arrangements = 40 flowers = 8/40 are daisies
Proportionality: where a/b = c/d
a = 2 daisies
b =10 flowers
c = 8 daisies
d = 40 flowers
We will know if the proportions are correct because the cross products will be equal.
ad = bc
2*40 = 10*8
80 = 80
One application of volume is determining the density of an object. Assume the object is made of a pure element (eg: gold). If we know the volume (v) of the object, and we know the mass (m), then we can use the formula D = m/v to figure out the density D. Knowing the volume is also handy to determine if the object can fit into a larger space or not. Another application is figuring out how much water is needed to fill up the inner space of the 3D solid (assuming it's hollow on the inside).
The surface area is handy to figure out how much material is needed to cover the outer surface. This material can be paint, paper, metal sheets, or whatever you can think of really. A good example is wrapping a present and the assumption is that there is no overlap.
Answer:
Step-by-step explanation:
So we have y-3=2(x+4)
So the first thing we want to do is distribute the 2 in front of the (x+4)
2(x+4) = 2x+8
Which means we have:
y-3=2x+8
Remember we need to get it into the form y=mx+b
As you can see here the 3 is preventing our equation from being in that form to we need to add it to both sides. This leaves us with:
y - 3 + 3 = 2x+8+3
Which gives: y = 2x+11
Therefore the slope form of this equation is y = 2x+11
Check the picture below.
so the perimeter will be, 3+3+3+3+3+3 plus the circumference of those two semi-circles, now, the two semi-circles together form a whole circle, whose radius is 3, so the perimeter will be 3+3+3+3+3+3 plus the circumference of a full circle with a radius of 3.
