A Metal rod is 7/8 m long it will be cut into pieces that are each 1/56 meters long how many pieces will be made from the road ?

1 answer:

7 0

Namely, how many times does 1/56 go into 7/8? well, let's check

$\bf \cfrac{\quad \frac{7}{8}\quad }{\frac{1}{56}}\implies \cfrac{7}{8}\cdot \cfrac{56}{1}\implies \cfrac{7}{\underline{8}}\cdot \cfrac{\underline{8}\cdot 7}{1}\implies \cfrac{49}{1}\implies 49$

Which of the following constants can be added to x2 + x to form a perfect square trinomial?

solmaris [256]

The constant should be added to form a perfect square trinomial will be 1/4. Then the correct option is D.

<h3>What is a quadratic equation?</h3>

It's a polynomial with a value of zero. There exist polynomials of variable power 2, 1, and 0 terms. A quadratic equation is an equation with one statement in which the degree of the parameter is a maximum of 2.

The expression is x² + x.

Then the constant should be added to form a perfect square trinomial.

Then the constant will be

The square of the half of the coefficient of the variable x is to be added to make a perfect square.

Then the constant will be 1/4.

Then the perfect square will be

$\rm \rightarrow x^2 + x + \dfrac{1}{4}\\\\\\\rightarrow x^2 + 2 \times \dfrac{1}{2} x + \left (\dfrac{1}{2} \right )^2\\\\\\\rightarrow \left (x + \dfrac{1}{2} \right)^2$

Answer:

120 ft

Step-by-step explanation:

The distance the gravel covers is the total distance times the percentage that the gravel covers

We know the gravel covers 66 ft and the percentage is 55%

distance gravel = total distance * percentage

66 = total distance * 55%

66 = total distance *.55

Divide each side by .55

66/.55 = total distance *.55/.55

120 = total distance

If a histogram is right skewed, which will be greater the mean or the median? Type a single word answer in the space

Mandarinka [93]

Answer:

Mean is greater

Step-by-step explanation:

For a skewed distribution, then the tail is longer to one side from the center than to the other. In a right skewed distribution, the tail is longer to the right.

When a distribution is skewed, the mean will be closer to the tail Than the median. Therefore. For a right skewed histogram, the mean is closer to the tail of the histogram and hence closer to the right. Once this happens, values closer to the right of a distribution are higher (number line). Thus the mean will be greater than the median.
