Answer:

-7.34 repeating

Step-by-step explanation:

A rational number is described as a number that can be expressed as a fraction or ratio of two integers and -7.34 repeating is the only option that does not fit this description. Repeating decimals can not be rational.

Answer:  [tex]-\sqrt{14}[/tex] in the lower right corner

===========================================================

Explanation:

A rational number is any fraction like 2/3 or 7/9. Pick any two integers, divide them, and you get a rational number. Zero cannot be in the denominator.

Based on that, we can see that 129/999 is rational, which is crossed off the list of potential answers.

Furthermore, [tex]\sqrt{16} = 4 = \frac{4}{1}[/tex] is also rational since we can form a fraction of integers. Cross this off the list as well. Always try to simplify the expression as much as possible.

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

When converting a fraction to decimal form, it turns out that any rational number has either two cases:

This means the number [tex]-7.\overline{34}[/tex] = -7.3434343434... is also rational, which is crossed off the list also.

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

The only thing left is [tex]-\sqrt{14}[/tex] which is not rational, and therefore we consider it irrational. We cannot form a fraction of integers to represent this square root value. Note how 14 is not a perfect square.

Answer:

x = 50°

Step-by-step explanation:

130 and x are adjacent angles on a straight line and sum to 180° , so

x + 130° = 180° ( subtract 130° from both sides )

x = 50°

Answer:

x = - 2

Step-by-step explanation:

Reflection across the y-axis:

( x , 6 ) ------> ( - x , 6 )

Translation 2 units right and 4 units down:

( - x , 6 ) -------> ( - x + 2 , 6 - 4 ) = ( - x + 2 , 2 )

Dilation by a factor of 2:

( - x + 2 , 2 ) ------> ( ( - x + 2 ) × 2 , 2 × 2 ) = ( 8 , 4 ) ⇒

( - x + 2 ) × 2 = 8

- 2x + 4 = 8

- 2x = 4

x = - 2

Answer:

342.7 cubic cm

Step-by-step explanation:

Calculate the volumes of the cylinder and the prism. Subtract.

see image.

Volume is the amount of three-dimensional space enclosed by a closed surface. The volume of the solid is 342.655 cm³.

The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity called volume.

The volume of the solid is the difference between the volume of the cylinder and the volume of the square prism.

[tex]\text{Volume of the solid} =\text{Volume of the cylinder}-\text{Volume of the square prism}[/tex]

[tex]\text{Volume of the solid} =(\pi r^2 h)-(a^2 h)[/tex]

We know that the radius of the cylinder is 4 cm while the length of the side of the square prism is 4 and the height of both is 10cm. therefore, substituting the values,

[tex]\text{Volume of the solid} =(\pi\times 4^2 \times 10)-(4^2 \times 10)[/tex]

                               [tex]=4^2\times10 (\pi -1)\\\\= 342.655\RM\ cm^3[/tex]

Hence, the volume of the solid is 342.655 cm³.

Answer:

if c= 1+px^2+3p and b= 2p+6p^2 find an expression that equals 2c-b in standard form

2p² + 14p + 2

Step-by-step explanation:

Given that;

C= 1+p²+3p

B=2p+6p

The expression that equals to : 2C - -B will be;

2{1+p²+3p} - {-2p-6p}

2+2p²+6p + 2p + 6p

2p² + 6p +2p +6p +2

Answer:

your answer would be 9753/1000

Step-by-step explanation:

2 1/3-1.5x=12.3

step 1:

to solve for x. You have to add 2 1/3 to 12.3 and get x by itself.

2 1/3+ 12.3= 14.63..

step 2 :

now that you have x by itself you're going to divide both sides by x which is -1.5x.

-1.5x/ -1.5x     14.63/ -1.5  =  9.753  

step 3:

to put 9.753 in a fraction get rid of the decimal and put it over 1000 since there are 3 numbers after the decimal point.

so your final answer is 9753/1000

The money will she have after four years is $276.26, the correct option is D.

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.

Given

Sophia puts $250 in the bank with a 2.5% annual interest rate compounded monthly.

The compound interest is given by;

[tex]\rm Amount = Principal ( 1+\dfrac{Rate }{12})^{12\times Time}[/tex]

Substitute all the values in the formula

[tex]\rm Amount = Principal ( 1+\dfrac{Rate }{12})^{12\times Time}\\\\Amount =250(1+\dfrac{0.025}{12})^{12\times 4}\\\\Amount =250(1.002)^{48}\\\\Amount = 250 \times 1.10\\\\Amount=276.26[/tex]
