Answer:

x=8.25

Step-by-step explanation:

8x=66

x=66/8

x=8.25

Answer:   The equation of the line = y = 12x as s =4  because  y = (length of a square)x  when x is 1 and when x is 0     We then use and prove the formula  y2-y1  / x2 - x 1   and one we have the slope we can show the unit for x (or add it to the equation for proof below)   = s4  =  12x * 4         = isolate s =  s = (12x *4)/4 = (12x *4)  /  4 = to find length s      therefore p =  length s * 4  and  s =  12x * 4 / 4  in the example below                                     

4s = p (perimeter) The perimeter an be a linear but it has boundaries of end point = 4s so in order to find the equation of the line if s = y  and s =1 given y = 1 where a length of side is possible in unit form - Which means if a square truly is equal sides then each length in units would double equally and then triple equally and quadruple equally - If the square was 120mm each length then the actual 1/12 creates a low positive linear always unless the unit is 0-9  anymore it would show a lesser steep positive linear as higher numbers for when y = 1  Therefore if 120mm = 12cm   x/y = 12/1  matching coordinates (12 1)  rise over er run  point 1  and point 4(end point) therefore would be * 12 linear =x/y   or would be  * (unit length) linear =x/y in the 12 linear we would have coordinates   (48 4) end point and formula 48-12 / 4-1 = 36/3 = 12  which proves the slope is always the function measure of all sides = y = 12x  when x is 1 and when x is 0 given the example for when a length is 12cm

Step-by-step explanation:

 4s  =    12x * 4   could be the function based if using a length of 12cm  or equation of the line = y = 12x and s =4

Step-by-step explanation:

3 wholes, 12 tenths, 4 hundredths. After the change, it's 4 wholes, 2 tenths, and 4 hundredths. The sum is 4.24.

Answer:

In the begining you put 4 hundreths and 12 tenths in the next boxes you would put 4 wholes 2 tenths and 4 hundreths and the sum is 4.24

Step-by-step explanation: I have taken this quiz but the long green tens are your tenths and the the little blue blocks are hundredths and  the big orange ones are wholes. So you count them all and put them in the 2 boxes .

Answer:

yes, because the value of the angles in both the triangles are the same

Step-by-step explanation:

in triangle 1, the given value is 47 and 78. we can find the unknown value by taking 180 and minus 47 and 78, you will get 55°. in triangle 2, the given value is 47 and 55, like the previous step, take 180 and minus 55 and 47. you will get 78.

and now, you can find out that the three values in both the triangles are the same

Answer:

Yes, I guess you can say the triangles are similar. For example, all 4 sides are an acute angle. In addition, both triangles are missing 1 degree shown on the picture.

Answer:

525

Step-by-step explanation:

If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525

Answer:

The first two answers and the last one are correct.

Step-by-step explanation:

In order to check if the expressions are equivalent, look at the number in front (coefficient) and its sign (positive/plus or negative/minus), the letter (variable) and its exponent.

In the question the 3x² is a (positive or plus) +3x²

The 5a³ is a (negative or minus) -5a³

The 2y^4 is also (positive or plus).

All of the signs in the answers are the same as the question (as well as the number, letter, exponent) EXCEPT for the third answer has a different sign. It has NEGATIVE 2y^4 and POSITIVE 5a³ which are wrong.

The terms can be rearranged, but they MUST keep their positive or negative signs with them, and keep them the same sign as the original question.

Answer:

H. is the correct answer.

Step-by-step explanation:

You find range by subtracting the lowest amount from your data by the highest amount. The highest number in Ms. Gambino's class is 12, and the lowest is 5.

\(12-5=7\)  This is the range of Ms. Gambino's class

The highest number in Mr. Joe's class is 10 and the lowest is 5

\(10-5=5\\\) This is the range of Mr. Joe's class.

Therefore, the range in Mr. Joe's class is less than the range of data in Ms. Gambino's class.

Answer:

Step-by-step explanation:

To find the median, we need to arrange the data in ascending order:

70, 71, 72, 74

Since the data set has an even number of values, the median is the average of the two middle values. In this case, the two middle values are 71 and 72. Therefore, the median is:

(71 + 72) / 2 = 143 / 2 = 71.5

So, the median for the given set of data is 71.5.

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Answer: x=-25

Step-by-step explanation:

Concept to know:

When given a number that is cubic root, in order to solve the equation/function, you need to cube numbers on both sides.

Solve:

Given

∛5x+10=5

Subtract 10 on both sides

∛5x+10-10=5-10

∛5x=-5

Cube numbers on both sides

5x=-125

x=-25

Answer:

Step-by-step explanation:

If ∛5x+10=5, Find x

∛5x = 5 - 10

∛5x = -5

take both sides of equation to the power of 3

5x = -125

x = -125/5

x = -25

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.

b) The correct expression is given as follows: -8.6b + 28.

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.
