1 1/3 statues so only 1 whole statue.

Step-by-step explanation:

This would be 2/3 divided by 1/2

= 2/3 * 2

= 4/3 or 1 1/3 statues.

Answer:

Step-by-step explanation:

The student have 2/3 liter remaining and want to paint more statues khowing that each one require 1/2 liter .

to solve this exercice we must divide the remaing paint quantity by the quantity each statue needs .

this way :

(2/3)/(1/2)= (2/3)*(2)

= 4/3

We khow that 4/3≈1.33
so the student can paint onlu one more statue fully

The sum of the first ten terms of a linear sequence is 145. the sum of the next ten term is 445. find the sum of the first four

chubhunter [2.5K]

The sum of the first four terms of the sequence is 22.

In this question,

The formula of sum of linear sequence is

$S_n =\frac{n}{2}(2a+(n-1)d)$

The sum of the first ten terms of a linear sequence is 145

⇒ $S_{10} =\frac{10}{2}(2a+(10-1)d)$

⇒ 145 = 5 (2a+9d)

⇒ $\frac{145}{5} =2a+9d$

⇒ 29 = 2a + 9d ------- (1)

The sum of the next ten term is 445, so the sum of first twenty terms is

⇒ 145 + 445

⇒ $S_{20} =\frac{20}{2}(2a+(20-1)d)$

⇒ 590 = 10 (2a + 19d)

⇒ $\frac{590}{10}=2a+19d$

⇒ 59 = 2a + 19d -------- (2)

Now subtract (2) from (1),

⇒ 30 = 10d

⇒ d = $\frac{30}{10}$

⇒ d = 3

Substitute d in (1), we get

⇒ 29 = 2a + 9(3)

⇒ 29 = 2a + 27

⇒ 29 - 27 = 2a

⇒ 2 = 2a

⇒ a = $\frac{2}{2}$

⇒ a = 1

Thus, sum of first four terms is

⇒ $S_4 =\frac{4}{2}(2(1)+(4-1)(3))$

⇒ $S_4 =2(2+(3)(3))$

⇒ S₄ = 2(2+9)

⇒ S₄ = 2(11)

⇒ S₄ = 22.

Hence we can conclude that the sum of the first four terms of the sequence is 22.

The tables below show the values of f (x) and g (x) for different values of x:

dimaraw [331]

2(3)× = 3×+1 is equal when f(x) = g(x).
f(x) is equal to g(x) when x = 0.
Therefore, the solution to the equation 2(3)×=3×+1 is x = 0.

Suppose a jar contains 15 red marbles and 19 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same

Kay [80]

Answer: $\bold{\dfrac{35}{187}}$

Step-by-step explanation:

1st marble and 2nd marble

$\dfrac{15\ red}{34\ total}$ $\times$ $\dfrac{14\ red}{33\ total}$ $=\dfrac{15\times 14}{34\times 33}=\dfrac{5\times 7}{17\times 11}= \boxed{\dfrac{35}{187}}$
