Answer:

The circumference of circle is 15.7 feet

Step-by-step explanation:

First, you have to find the radius of circle by dividing the diameter by 2 :

$radius = diameter \div 2$

$radius = 5 \div 2$

$radius = 2.5 \: feet$

Next, you have to substitute it into the formula of circumference, C = 2×π×r where r represents radius :

$C = 2 \times \pi \times 5$

$let \: \pi = 3.14 \\ let \: r = 2.5$

$C = 2 \times 3.14 \times 2.5$

$C = 15.7 \: feet$

Sam has fewer baseball cards than Jill (she has 36). There are only three ways that he can arrange all of his cards in equal row

pantera1 [17]

Answer:

27, 30, 33

Step-by-step explanation:

Since Sam has fewer number of baseball cards than Jill who has 36 baseball cards and can arrange all his cards in only three ways, the possible number of baseball cards that Sam could have is 27, 30 or 33.

If he has 27 baseball cards, he can arrange 9 baseball cards per row in 3 rows

If he has 30 baseball cards, he can arrange 10 baseball cards per row in 3 rows

If he has 33 baseball cards, he can arrange 11 baseball cards per row in 3 rows

What number must you add to complete the square x^-8x=39

notsponge [240]

Answer:

Given equation: $x^2-8x =39$

when we complete the square , we take half of the value of 8 , then square it, and added to the left sides, we get;

$x^2-8x+4^2 = 39 +4^2$

∵8 is the value $(\frac{8}{2})^2$

Notice that, we add this both sides so that it maintains the equality.

then;

$x^2-8x+4^2 = 39 +4^2$

$(x-4)^2 = 39 + 16$ [ $(a-b)^2 = a^2-2ab+b^2$ ]

Simplify:

$(x-4)^2 =55$

The number must be added to complete the square is, $4^2 = 16$
