Answer:

7x² - 2x + 4

Step-by-step explanation:

(5x² + 2x + 11) - (7 + 4x - 2x²) = 5x² + 2x + 11 - 7 - 4x + 2x² =

(5x² + 2x²) + (2x - 4x) + (11 - 7) = 7x² - 2x + 4

Answer:

x=2

Step-by-step explanation:

We see that there is already a common variable that can be canceled out -- y. y+(-y)=0! (Alternatively you may also multiply an equation by negative 1 and do subtraction, but in this case it's already done for you)

So now we just do some addition.

2x+6x=8x

y+(-y)=0

7+9=16

This means that 8x=16. Now we solve!

(Divide both sides by 8)

We're left with x=2 :)

Answer:

42 or 48

Step-by-step explanation:

It's a acute angle so it's that one or that one.

Answer:

42 degrees

Step-by-step explanation:

180-132 = 48

90 + 48 = 138

180 - 138 = 42

Answer:

54 lick per 3 lollipops is a unit rate of 18 licks per lollipop.

36 is 2 times 18, so it needs 2 times as many licks as 18 lollipops.

36 2

I assume the last line is 5 lollipops.

If 1 lollipop takes 18 licks, then 5 lollipops take 5 * 18 licks.

5 * 18 = 90

90 5

Answer: i think 2 because 90 divided by 5 is 18 and 54 divided by 3 is 18 so

Answer:

Here :D

Step-by-step explanation:

look at one of the 30 central triangles.

Each will be isosceles with a vertex angle of 12°

base^2 = 1^2 + 1^2 - 2(1)(1)cos12°

= 2 - 2cos12°

so the perimeter is 30(2 - 2cos12°)

= 60 - 60cos12°

use your calculator if you need a decimal answer.

Answer:

$478.06

Step-by-step explanation:

let's first start out by figuring out the present value of the loan

((20540*1.0825)+955+57)-3900

Which gives me a value of 23246.55

I'm then going to assume that the 8.6% is a nominal interest rate meaning that the effectively monthly rate is equal to .086/12=.0072

Which means we have

23246.55=X(a angle 60 at .0072) (i'm using annuities to solve this if you don't know what this is just ask)

Solve this and get $478.06

Answer:lol it's -3

Step-by-step explanation: it's 3 because you had dirt 45.50 in your account and then you have to get books and those books will cost $3 more which means that you don't have that money since it indicates that in the problem which means that it would be -3 because you don't have the money so that's why I think it's negative 3.  

Answer:

The answer is B. Beta Mart

Step-by-step explanation:

First you convert everything to pints. So that would be:

Alpha - 2 pints is $1

Beta - 8 pints is $3

Gamma - 1 pint is $0.54

Delta - 4 pints is $1.86

Then you find the unit rate of each. That would be:

Alpha - 1 pint is $0.50

Beta - 1 pint is $0.375(0.38)

Gamma - 1 pint is $0.54

Delta - 1 pint is $0.465(0.47)

Whichever unit rate is the least (Beta Mart) has the lowest rate. Even though it says ounces, it would still be the same answer.

• The single-digit numbers 1-9 do not have any repeated digits, so they contribute 9 numbers.

• Of double-digit numbers 10-99, the first digit can be picked from 1-9 and the second from 0-9 minus whichever one is picked for the first digit, so they contribute 9×(10 - 1) = 81 numbers.

• Of the triple-digit numbers 100-999, the first digit is picked from 1-9 and the second and third digits from 0-9, so they contribute 9×(10 - 1)×(10 - 2) = 648 numbers.

So there are 9 + 81 + 648 = 738 numbers from 1-999 without repeated digits.

Of these numbers, the ones that are even end in 0, 2, 4, 6, or 8.

• Of the single-digits, there are 4 numbers.

• Of the double-digits, the first digit can be chosen from 1-9 and the second from {0, 2, 4, 6, 8}.

•• If the first digit is odd and picked from {1, 3, 5, 7, 9}, then they contribute 5×5 = 25 numbers.

•• If the first digit is even, then they contribute 4×(5 - 1) = 16 numbers (because the first digit can't be 0).

• Of the triple-digits, the third digit is picked from {0, 2, 4, 6, 8}.

•• If both the first and second digits are odd, then they contribute 5×(5 - 1)×5 = 100 numbers.

•• If the first is odd and the second is even, then they contribute 5×5×(5 - 1) = 100 numbers.

•• If the first is even and the second is odd, then they contribute 4×5×(5 - 1) = 80 numbers.

•• If both are even, then they contribute 4×(5 - 1)×(5 - 2) = 48 numbers.

So there are 4 + (25 + 16) + (100 + 100 + 80 + 48) = 373 even numbers from 1-999 with no repeating digits.

Answer:

No change ; = ; research ; parameter

Step-by-step explanation:

The Null hypothesis in a statistical test is always the initial truth which always means that a research scenario or statement is as it is or that there is no change whatsoever. The null hypothesis is usually denoted as H0 ; because it is always the initial truth or accepted claim, it usually takes a equal to sign, this denotes that, there is no change in parameter, either the population mean or any other statistical measure we wish to test. The alternative hypothesis on the other hand always negated the null hypothesis, because it brings up a claim which is to check or peruse the Null hypothesis, hence, it is a research hypothesis, denoted as Ha: ;

The alternative hypothesis contains the statement about the population parameter we wish to test( parameter is a measured value about the population).

Answer:

Option B, There is no correlation between the last digit of phone number and the quiz grade.  

Step-by-step explanation:

The values on the scatter plot are dispersed and hence no best fit curve can be drawn for this data set.

Hence there is no relation between the two variables that is last digit of phone number and the quiz grade.

Answer:

  (3, 4)

Step-by-step explanation:

Put the numbers in the formula and do the arithmetic.

  Q = (A + B + C)/3

  Q = ((1, 1) +(4, 5) +(4, 6))/3 = (1+4+4, 1+5+6)/3 = (9, 12)/3

  Q = (3, 4)

The centroid is (3, 4).

Step-by-step explanation:

Area of Figure

= Area of Parallelogram + Area of Semicircle

= (26)(13) + 0.5π(24/2)²

= 338 + 72π

= 564.2.

Answer:

Area of the figure :---

Area of the parallelogram+area of the semicircle

(26×13)+(1/2)π(12)²

=338+72π

=338+226.2

=564.2 square unit

Given:

Score in first round = 5 points

Score in second, third and fourth rounds was identical.

A participant has to score a total of at least 30 points in the first four rounds combined to move on to the fifth and final round.

To find:

The inequality for the given problem.

Solution:

Let p be the number of points, p, that Steward scored in each of the second, third, and fourth rounds.

Score in first 4 rounds = Score of 1st round + Score of 2nd round + Score of  1s 3rd round + Score of 4th round

Score in first 4 rounds [tex]=5 + p + p + p[/tex]

                                     [tex]=5 +3p[/tex]

A participant has to score a total of at least 30 points in the first four rounds combined to move on to the fifth and final round. It means the total score in first 4 rounds must be greater than or equal to 30.

[tex]5+3p\geq 30[/tex]

Therefore, the correct option is A.
