Answer:

The amount of the bill is dependent on the number of texts sent. Let y be the bill amount and x the number of texts. Then x is independent and y is dependent. This is because x can be any non-negative number, but y depends upon it. You cannot find the bill without knowing the number of text messages, right?

Answer:

the amount of money that you are charged

Step-by-step explanation:

the dependent variable is defined as a variable which changes depending on the other variables that are manipulated in a function so what that means is that the inputs are independent variables and the outputs are the dependent variables and in the case of this question the amount of texts sent are the independent variables and the amount charged is the dependent variable

-1/3 It cant be the others because -1 is already at the edge and is not the number, 1/3 is positive but -1/3 is left of zero, therefore negative and 1 is right of zero, so is positive.

Which expression is equivalent??? help!

dexar [7]

Answer:

The equivalent expression for the given expression $\sqrt[3]{256x^{10}y^{7} }$ is

$4x^{3} y^{2}(\sqrt[3]{4xy} )$

Step-by-step explanation:

Given:

$\sqrt[3]{256x^{10}y^{7} }$

Solution:

We will see first what is Cube rooting.

$\sqrt[3]{x^{3}} = x$

Law of Indices

$(x^{a})^{b}=x^{a\times b}\\and\\x^{a}x^{b} = x^{a+b}$

Now, applying above property we get

$\sqrt[3]{256x^{10}y^{7} }=\sqrt[3]{(4^{3}\times 4\times (x^{3})^{3}\times x\times (y^{2})^{3}\times y )} \\\\\textrm{Cube Rooting we get}\\\sqrt[3]{256x^{10}y^{7} }= 4\times x^{3}\times y^{2}(\sqrt[3]{4xy}) \\\\\sqrt[3]{256x^{10}y^{7} }= 4x^{3}y^{2}(\sqrt[3]{4xy})$

∴ The equivalent expression for the given expression $\sqrt[3]{256x^{10}y^{7} }$ is

$4x^{3} y^{2}(\sqrt[3]{4xy} )$

Last year the girl's basketball team had 8 fifth-grade students and 7 sixth-grade students.What was the ratio of sixth-grade stu

Rashid [163]

Answer:

The ratio of sixth-grade students to fifth-grade students on the team was 7 : 8.

Step-by-step explanation:

Given:

The girl's basketball team had 8 fifth-grade students and 7 sixth-grade students.

Now, to find the ratio of sixth-grade students to fifth-grade students on the team.

Number of fifth-grade students = 8.

Number of sixth-grade students = 7.

Now, to get the ratio of sixth-grade students to fifth-grade students on the team :

$Number\ of\ sixth-grade\ students:Number\ of\ fifth-grade\ students$

$=7:8.$

Therefore, the ratio of sixth-grade students to fifth-grade students on the team was 7 : 8.
