The area of the rect. is 100 ft times 64 ft, or 6400 ft^2.

Let's list factors of 6400: 64,100

64= 2^6

100= 2^2*5^2

Here we see that 2 appears 8 times as a factor, and 5 appears 2 times:

6400 = 2^6 * 10^2 = 2^8*5^2

Determine the correct set up for solving the equation using the quadratic formula.

netineya [11]

Answer: B

Begin by simplifying the given equation, so it's rearranged into standard form. Move all the terms onto one side, so they equal 0. This would result with $4x^{2}$ -3x-9=0. Quadratic formula is (-b±√(b²-4ac))/(2a). Standard form follow this variable format: $ax^{2}$ +bx+c. Use the numbers that correspond with each variable to substitute them into the quadratic formula. This would be

(-(-3)±√(-3²-4(4)(-9)/2(4).

3 giant Sandwiches,

8 friends,

Have to be shared equally,

Each friend gets = $\frac{3}{8}$

If we solve, we'll end with 0.375 Which is between 0 and 1.

So,
It will lie in between 0 and 1.

If Sam has 6/8 apples and he gives 4/6 away How much doe she have left?

Margaret [11]

Answer: 1/12 apples left

Step-by-step explanation:

Find the least common multiple (LCM)

8: 8, 16, 24, 32, and so on

6: 6, 12, 18, 24, and so on

Both denominators have a common multiple of 24, so let's use that as the LCM

Whatever you do the denominator, you must do to the numerator, and vice versa.

6*4=24, so you have to multiply 4 to the numerator

4*4=16, so the fraction is 16/24

Then do it for the next fraction

8*3=24, so do 6*3=18

18/24

Then subtract them

18/24 - 16/24= 2/24

Then simplify and you get 1/12

Describe the relationship between ∠2 and ∠8

AURORKA [14]

Answer:

Alternate Interior Angles

Step-by-step explanation:

Angles can be corresponding; alternate or same side; or interior or exterior. The angles 2 and 8 are on opposite sides of the transversal; this means that they must be alternate angles. Additionally, they are both within the parallel lines, so they are interior. Alternate interior angles are always congruent. Therefore, their measurements must be equal.
