Its C, It can't be equal because it is not dividing by 1, It can't be less than 0.4 because if you divide by a decimal the quotient will increase. So the obvious choice is C because it will be greater than 0.4. Also a question for you, why use this website to get answers when there are online calculators....

If m <2 =40o then What does m <z equal

For the small triangle, <2=40, so we can add 40 to the 90 degree angles to get 130. subtract 180-130 to get the remaining angle in the small triangle to get 50.
The remaining angle, 50 is also the angle to the large triangle. So Since the top angle of the large triangle is =90. So add the 50 and 90 to get 140.Subt 180-140 because the total of the large angles should be 180 degrees. That leaves 40 degrees for angle z. So that would be B.

How many of the numbers from 10 through 92 have the sum of their digits equal to a perfect​ square?

All the numbers in this range can be written as 10d_1+d_0 with d_1\in\{1,2,\ldots,9\} and d_2\in\{0,1,\ldots,9\}. Construct a table like so (see attached; apparently the environment for constructing tables isn't supported on this site...)

so that each entry in the table corresponds to the sum of the tens digit (row) and the ones digit (column). Now, you want to find the numbers whose digits add to perfect squares, which occurs when the sum of the digits is either of 1, 4, 9, or 16. You'll notice that this happens along some diagonals.

For each number that occupies an entire diagonal in the table, it's easy to see that that number n shows up n times in the table, so there is one instance of 1, four of 4, and nine of 9. Meanwhile, 16 shows up only twice due to the constraints of the table.

So there are 16 instances of two digit numbers between 10 and 92 whose digits add to perfect squares.

To divide one by two means to take one and split it in half. For example, if you have 1 pie and you / by 2. You took one whole pie and made two, half slices. 

Your result is; from one pie, you have two pieces, if you divide by five, you get five pieces. So on & so so forth. But be careful, because each time you divide more and more, the slices get smaller & smaller. Hope this helps.

It is in standard form because the coefficients are in order from highest to lowest. c. It is not in standard form because the constant should be the first term. d. It is not in standard form because it can be further simplified.

Answer:

a. It is in standard form because the exponents are in order from highest to lowest.

Step-by-step explanation:

-24x^7-12x^2-9x+6

A polynomial is in standard form when the exponents are in order from highest to lowest.

In the given expression , the exponent is in order x^7 and then x^2 and then x

Standard form does not depends on the coefficient of each each.

The given polynomial is in standard form because the exponent are in order from highest to lowest.

A spinner with five equal-sized colored sections is spun with the results shown in the table. Based on the experimental probability, predict the number of blue results for 200 trials. Red :15 Orange : 16 Yellow :14 Green : 19 Blue : 19 16 20 32 4

Answer:  46

Step-by-step explanation:

From the table , The number of times spin got results as blue = 19

Total results = 15+16+14+19+19=83

Then , the experimental probability to get blue :-

\dfrac{19}{83}

If the total number of trails = 200

Then , the estimated number of blue results = \dfrac{19}{83}\times200

=45.7831325301\approx46

Hence, the predicted number of blue results for 200 trials= 46

Malene wrote the equation x² + 8x + 60 = x² + 12x + 20 to show that the area of a changed rectangle is 60 cm² greater than the area of the original rectangle. How did the rectangle change? 1 was added to each side. 2 was added to each side. 8 was added to each side. 10 was added to each side.

Answer:

2 was added to each side

Step-by-step explanation:

Given that a rectangle when changed sides, the area became 60 greater than the original

The equation given is

x^2 + 8x + 60 = x^2 + 12x + 20

From the above equation we can see that the original area wasx^2 + 8x

and it changed to

x^2 + 12x + 20

Original rectangle dimensions= factors of area terms = x , x+8

New rectangle dimensions = factors of x^2 + 12x + 20

=x+2, x+10

Thus we have both length and width increased by 2 units.

Brian, Chris, and Damien took a math test that had 20 questions. The number of questions Brian got right is 14 more than 1/4 the number of questions Chris got right. Damien correctly answered 2 less than 5/4 the number of questions Chris answered correctly. If Brian and Damien have the same score, which statement is true?

Answer: only true statement is ---The number of questions Brian got right is 14 more than 1/4 the number of questions Chris got right

Step-by-step explanation:

Let Brain and Damien both scored x while Chris scored y then

According to the first relation

x=\frac{y}{4}+14

where x and y are less than or equal to 20 .

For y=20 , x=19     possible value

According to the second relation

x=y\times \frac{5}{4}-2

where x and y are less than or equal to 20 .

For y=20 , x= 23 not possible

so only true statement is ---The number of questions Brian got right is 14 more than 1/4 the number of questions Chris got right

The answer is 10 was added to each side.

x² + 8x + 60 = x² + 12x + 20
____
Subtract x
² from both sides:

x² + 8x + 60 - x² = x² + 12x + 20 - x²
8x + 60 = 12x + 20
60 - 20 = 12x - 8x
40 = 4x
x = 40/4
x = 10

So, 10 was added to each side.
