2. Find the product of 2/7 x 5/6

Mathematics
1 answer:
alex41 [277]3 years ago
8 0

Multiply the numerators together and the denominators:

2/7 x 5/6 = (2x 5) / (7x6) = 10/42 this can be reduced to 5/21

The answer is 5/21

-4/5 x 7/10 = (-4x7) / (5x 10) = -28/50

This can reduce to -14/25

Hulk left home and walked 8 blocks west. Then he turned and walked 6 blocks north. If each block is 500 ft. long, how far is Hul
son4ous [18]
The answer is 5000 ft 

His displacement is actually the hypotenuse (c) of the triangle with sides 6 blocks and 8 blocks.
According to the Pythagorean theoreme:
c² = a² + b²
c² = 6² + 8²
c² = 36 + 64
c² = 100
c = √100
c = 10 blocks

Since 1 block is 500ft long, then 10 blocks are 5000 ft long:
1 : 500ft = 10 : x
x = 10 * 500ft / 1 = 5000 ft

34 divided 5323 in simple form
joja [24]

The value when 34 is divided by 5323 is 0.00639.

<h3>What is division?</h3>

It should be noted that division simply means the opposite of multiplication. It represents the way numbers are combined in order to make new numbers.

The steps include:

1: Take the dividend's first digit starting from the left in step one. Verify if this digit exceeds or is equal to the divisor.

2. Next, divide it by the divisor, and write the result as the quotient on top.

3. Subtract the outcome from the digit, and then put the difference below.

4: Decrease the dividend's subsequent digit (if present).

5: Carry out Step 4 again.

In this case, 34 divided 5323 will be 0.00639. It should be noted that this illustrates a decimal.

Suppose an airline policy states that all baggage must be box shaped with a sum of​ length, width, and height not exceeding 114
NISA [10]

Answer:

Step-by-step explanation:

Represent the length of one side of the base be s and the height by h.  Then the volume of the box is V = s^2*h; this is to be maximized.

The constraints are as follows:  2s + h = 114 in.  Solving for h, we get 114 - 2s = h.

Substituting 114 - 2s for h in the volume formula, we obtain:

V = s^2*(114 - 2s), or V = 114s^2 - 2s^3, or V = 2*(s^2)(57 - s)

This is to be maximized.  To accomplish this, find the first derivative of this formula for V, set the result equal to 0 and solve for s:

dV

----- = 2[(s^2)(-1) + (57 - s)(2s)] = 0 = 2s^2(-1) + 114s - 2s^2

ds

Simplifying this, we get dV/ds = -4s^2 + 114s = 0.  Then either s = 28.5 or s = 0.

Then the area of the base is 28.5^2 in^2 and the height is 114 - 2(28.5) = 57 in

and the volume is V = s^2(h) = 46,298.25 in^3
