Sonja [21]3 years ago

Na₂O has a molecular mass of (2 x 23.0) + 16 = 62. One mole of any substance is its molecular mass in grams, so if 1 mole of Na₂O = 62.0-g, then 5 moles would be 310-g ...(62.0g/mol x 5-mol) = 310-g Na₂O

Giovanni was playing with blocks and started with one blue triangular block and kept adding more
raketka [301]

Blocks would he need on the 12th step of the pattern is 34.

The correct option is A

<h3></h3><h3>What is series?</h3>

A series is the cumulative sum of a given sequence of terms.

Given:

We can write the series as follows:

1,4,7,10,13,.......

First term =1

common difference= 4-1=3

Using Arithmetic series

a_{12}\\= a+11d

    =  1 +11*3

    = 1+33

    = 34.

Hence, 34 blocks need on 12th step.

A pair of angles is supplementary if the sum of their measures is 180 degrees. A pair of angels is complementary if the sum of t
Hunter-Best [27]

Answer:

The measure of the complement =

= 80°

The measure of the supplement=

= 170°

Step-by-step explanation:

Let

90-x equal the degree measure of its complement

180-x equal the degree measure of its supplement.

We are told in the question that: the supplement of a given angle is 10 degrees more than twice its complement.

Hence, the Equation is;

(180 - x) = 10° + 2(90 - x)

180 - x = 10 + 180 - 2x

Collect like terms

-x + 2x = 10 + 180 - 180

x = 10°

Hence,

The measure of the complement =

90 - x

= 90 - 10

= 80°

The measure of the supplement=

180 - x

= 180 - 10

= 170°

36% of the beans in Pythagoras's soup are lentils, and 33 1/3 of those lentils are green. If Pythagoras removes all the green le
bonufazy [111]

Answer:

Value of x is 88

Step-by-step explanation:

We have,

Percentage of lentils in the soup = 36% = 0.36

Fraction of the lentils which are green = 33\frac{1}{3}

Thus, the amount of green beans in the soup are = 0.36\times 33\frac{1}{3} = 0.36\times \frac{100}{3} = 0.36 × 33.3 = 11.99 ≅ 12.

So, the percentage of the green beans = 12%

The percentage of the original beans in the soup = (100-12)% = 88%

Hence, the value of x is 88.
