Sergeeva-Olga [200]

Answer:

I got 2 as an answer

Step-by-step explanation:

$( {3x}^{4} ) - 5 = 43 \\ ( {3x}^{4} ) = 43 + 5 \\ ( {3x}^{4} ) = 48 \\ \frac{ {3x}^{4} }{3} = \frac{48}{3}$

${x}^{4} = 16 \\ \sqrt[4]{ {x}^{4} } = \sqrt[4]{16} \\ x = 2$

Can you please help me and explain this in a way that I can understand

Answer:

180 Degrees

Step-by-step explanation:

So, m∠1 = m∠2 = m∠3 means that these angles are the same degrees

The question asks whats the degree of m∠CDG so first we find those points. In this image, it looks like points C,D and G form a line which is also equivalant to 180.

I hope you understand! If not, i'll try to elaborate more

In 2006, the population of the country was 30.4 million. This represented an increase in population of 7.6 % since 2001. What w

Molodets [167]

Answer:

28.25 million

Step-by-step explanation:

Population of the country:

in 2001 - x million
in 2006 - 30.4 million

Population of the country as percent:

in 2001 - 100%
in 2006 - 100% + 7.6% = 107.6%

Write a proportion:

$\dfrac{x}{30.4}=\dfrac{100}{107.6}$

Cross multiply:

$107.6\cdot x=30.4\cdot 100$

Divide by 107.6:

$x=\dfrac{30.4\cdot 100}{107.6}=\dfrac{3,040}{107.6}\approx 28.25$

Help me please:(((((

Answer:

• Consider points (2, 0) and (0, 6) spotted from the graph.

${ \boxed{ \rm{slope = \frac{y _{2} - y _{1} }{x _{2} - x _{1} } }}}$

• substitute:

${ \rm{slope = \frac{6 - 0}{0 - 2} }} \\ \\ { \rm{ = \frac{6}{ - 2} }} \\ \\ { \boxed{ \boxed{ \tt{ \: \: slope = - 3 \: \: }}}}$
