Answer:

a) 256

b) 8

Step-by-step explanation:

a) as it says in the question, each box contains 64 stickers. Mrs Kim bought 4 boxes , so she has 4 times more than a single box (64 stickers)

The calculation is simple: 64 x 4, which equals 256

b) If there are 256 stickers all-together and she has 32 people to share them equally with, you have to divide 256 by 32 to see how many stickers each person will get:

256 ÷ 32 = 8

What is the best approximation for the perimeter of a semicircle with a dimeter of 12cm?

taurus [48]

Answer is choice B: the circumference of a circle is the same as perimeter and is defined by πd (or pi times diameter) We can cut this in half because we are working with a semicircle: so we have 6π which approximates to the value in answer when using 3.14 for pi Woops: forgot to add the diameter of 12 so we would have 30.84

The table below shows the heights of several books. Jean stacks a dictionary on top of her novel. How high is the stack of the t

aev [14]

Answer:

The height of the stack = $5\frac{1}{4}$ in

Explanation:

We are given that Jean stacks a dictionary on top of a novel.

This means that the total height of the stack will be equal to the height of the dictionary added to the height of the novel.

From the givens, we have:

height of dictionary = $4\frac{1}{2}$ in

height of novel = $\frac{3}{4}$ in

Now, adding the two height, we will have:

Total height of stack = height of novel + height of dictionary

Total height of stack = $\frac{3}{4}+4 \frac{1}{2} = \frac{3}{4}+ \frac{18}{4}= \frac{21}{4}=5 \frac{1}{4}$ in

Hope this helps :)

Solve 5x^2 - 7x + 2 = 0 by completing the square.

Reika [66]

Answer: The correct option is (c) $\dfrac{49}{100}.$

Step-by-step explanation: We are given to solve the following quadratic equation by the method of completing the square:

$5x^2-7x+2=0~~~~~~~~~~~~~~~~~~~(i)$

Also, we are to find the constant added on both sides to form the perfect square trinomial.

We have from equation (i) that

$5x^2-7x+2=0\\\\\Rightarrow x^2-\dfrac{7}{5}x+\dfrac{2}{5}=0\\\\\\\Rightarrow x^2-2\times x\times \dfrac{7}{10}+\left(\dfrac{7}{10}\right)^2+\dfrac{2}{5}=\left(\dfrac{7}{10}\right)^2\\\\\\\Rightarrow \left(x-\dfrac{7}{10}\right)^2=\dfrac{49}{100}-\dfrac{2}{5}\\\\\\\Rightarrow \left(x-\dfrac{7}{10}\right)^2=\dfrac{49-40}{100}\\\\\\\Rightarrow \left(x-\dfrac{7}{10}\right)^2=\dfrac{9}{100}\\\\\\\Rightarrow x-\dfrac{7}{10}=\pm\dfrac{3}{10}\\\\\\\Rightarrow x=\pm\dfrac{3}{10}+\dfrac{7}{10}.$

So,

$x=\dfrac{3}{10}+\dfrac{7}{10},~~~~~~~~x=-\dfrac{3}{10}+\dfrac{7}{10}\\\\\\\Rightarrow x=\dfrac{10}{10},~~~~~~~~\Rightarrow x=\dfrac{-3+7}{10}\\\\\\\Rightarrow x=1,~-\dfrac{2}{5}.$

Thus, the required solution is $x=1,~-\dfrac{2}{5}.$ and the value of the constant added is $\dfrac{49}{100}.$

Option (c) is correct.
