96÷2=48
63-48=15

So Sam should give Peter 15 of his stamps so that Peter will have twice as many stamps as him.

Answer:

Sam must give Peter 10 stamps so that Peter has twice as much as him.

Step-by-step explanation:

Although the exercise could be done using equations, I will teach you a much simpler method to find the answer to this type of exercise: add the stamps of Sam and Peter:

96 + 63 = 159

Since one must have twice the other, you will have to divide the total value into 3 (then two parts will correspond to Peter and 1 one to Sam)

159/3 = 53

With this value, Sam must have only 53 stamps and give the rest to Peter, and since Sam has 63 stamps, he will have to give Peter 10, with which Peter will have 106 stamps, which is double 53.

Answer:

Step-by-step explanation:

Look at the figure attached below, we know that the area of the cone is the sum of area of circle part and cone part of the figure.

to find the surface area of the cone, first measure the radius of the base and find the area of the circle part by formula $\pi r^2$ . Then measure the side (slant height) length of the cone part and find the area of the cone part by the formula $\pi rl$ .

Now the surface area of the cone is circumference of the circle plus area of the cone part.

i.e. $surface\ Area\ of\ the\ cone=\pi r^{2}+\pi rl$

From the above discussion we concluded that surface area of the cone does not depend only on the circumference of the base but also we need side length of the cone part as well thus all cones with a base circumference of 8 inches will not have the same surface area.

What are the roots of 2x^2+10×-48=0

mojhsa [17]

X=-8,3.
divide all terms by the two in the first term to get x^2+5x-24=0. Then find the factors. To do so, find what two numbers can be multiplied to get 24, and whether those two numbers can be added or subtracted to get the middle term (5). Since 8x(-3)=24 and 8-3=5, (x+8) and (x-3) are the factors. Then set the factors equal to zero. Add or subtract these numbers to the other side of the equation and you then get x=-8,3. These are the roots.
