477

The value of the first 7 from the left is 70.

If you divide 70 by 10, you get the value of the second seven, 7.

Another way to know this is equivalent fractions:

1/10 = 7/10

10 X 7 = 70
1 X 7 = 7

May I know why is the answer 1/2? Any idea Thank you!

ElenaW [278]

let's put value of t in equation.

x = 2√t

x = 2√y

x/2 = √y

(x/2)^2 = y

y = x^2 /4

now let's differentiate it with respect to x.

dy/dx = 2x/4 = x/2

differentiating again wrt to x

d^2y/dx^2 = 1/2

There are 9.88 grams of sugar in 4 servings of grapes. How many grams of sugar are in a single serving of grapes?

Korolek [52]

Ok so grapes,

We have 4 servings and 9.88 grams total, so to find one serving we just need to divide by 4.

9.88/4 = 2.47 per serving

A box contains 6 black pens, 4 blue pens, and 7 red pens. Without looking, Clarissa randomly picks a black pen out of the box. I

Answer:

31.35%

Step-by-step explanation:

<h3>Initial reading:</h3>

In the box, there are:

6 Black pens
4 blue pens
7 red pens

Total number of pens in the box = 6 + 4 + 7

= 17

If we count pens as outcomes the total number of possible outcomes are 17.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

<h3>New reading:</h3>

Clarissa takes out a black pen from the box.

That reduces the number of black pens by 1 which increases the total number of pens by 1 as well.

So now:

Number of black pens = 6 - 1 = 5 
Total number of pens = 17 - 1 = 16

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

<h3>Probability:</h3>

$\boxed{ \mathsf{probability = \frac{favorable \: outcomes}{total \: outcomes} }}$

If we want her to pick up a black pen, and she ends up picking one. So, we can say that the outcome is in our favor.

That makes it,

the number of favorable outcomes = number of black pens

= 5

and total outcomes = Total number of pens

= 16

$\implies\mathsf{probability = \frac{5}{16} }$

For showing it as some percent we'll just multiply the fraction by 100

$\implies \mathsf{ \frac{5}{16} \times 100 }$

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

<h3>As a percent:</h3>

$\implies \mathsf{ \underline{ 31.25 \: \% } }$
