A square window has an area of x2 + 22x + 121 square feet. Find the length of one side of the square.
A) (x + 11) feet

B) (x – 11) feet

C) (x – 6) feet

D) (x + 6) feet

Answers

The answer is A(x+11)

x + 11 ft

Step-by-step explanation:

x² + 22x + 121 ft² = area of square

x² + 11x + 11x + 121 ft² = side²

x(x + 11) + 11(x + 11) ft² = side²

(x + 11)(x + 11) ft² = side²

(x + 11)² ft² = side²

x + 11 ft = side²

Angle Z is 21 degrees larger than twice the measure of angle T. If ∠Z and ∠T are supplementary, what is the measure of angle T? *

Answers

angle T = x

angle Z = 2x + 21

We know that supplementary angles add up to 180 degrees.

180 = x + 2x + 21

Combine like terms.

180 = 3x + 21

Subtract 21 from both sides.

159 = 3x

Divide both sides by 3

53 = x

angle T = 53 degrees

At a convenience store, you have a choice of five diet drinks, 10 regular drinks, six bags of fat-free chips, and 10 bags of regular chips. What is the probability that you will buy a regular drink and a regular bag of chips?

Answers

Answer:

I guess that the purchase is at random, then let's see the possible options:

5 diet drinks.

10 regular drinks.

Total drinks = 15

6 bags of fat-free chips

10 bags of regular chips.

Total chips = 16.

Probability of buying at random, a regular drink is equal to the number of regular drinks divided the total number of drinks:

p1 = 5/15 = 1/3

Probability of buying at random a regular bag of chips, we use the same reasoning as before.

p2 = 6/16 = 3/8

The joint probability will be equal to the product of the individual probabilities:

P = p1*p2 = (1/3)*(3/8) = 1/8.

Answer:

the answer is 5/12

Prove that: (1 + cos A)^2 - (1 - cos A)^2/
sin^2 A=
4cosec A. cotA​

Answers

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

cosec x = [tex]\frac{1}{sinx}[/tex] , cot x = [tex]\frac{cosx}{sinx}[/tex]

Consider the left side

[tex]\frac{(1+cosA)^2-(1-cosA)^2}{sin^2A}[/tex] ← expand and simplify numerator

= [tex]\frac{1+2cosA+cos^2A-(1-2cosA+cos^2A}{sin^2A}[/tex]

= [tex]\frac{1+2cosA+cos^2A-1+2cosA-cos^2A}{sin^2A}[/tex]

= [tex]\frac{4cosA}{sin^2A}[/tex]

= 4 × [tex]\frac{1}{sinA}[/tex] × [tex]\frac{cosA}{sinA}[/tex]

= 4cosecAcotA

= right side,  thus proven

Cypress Middle School wants to have a fundraiser to buy art supplies. Fundraiser A will give the school $1.50 for each order placed plus $75 as a bonus. Fundraiser B will give the school $3.00 for each order placed, but no bonus. How many orders must be placed in order for the total amount of money earned by each fundraiser to be the same? a 150 b.5 c.17 d.50

Answers

Answer:

50

Step-by-step explanation:

Let the number of orders required be x

Fund raiser A , 1.50 for each other plus bonus of 75

for x orders, we have 1.50 * x = 1.50x

Add the bonus = 1.50x + 75

Fund raiser B, $3 for each other , no bonus

Total from fund raiser B is 3 * x = 3x

So to make them equal, we ensure that e equate both values;

3x = 1.5x + 75

3x -1.5x = 75

1.5x = 75

x = 75/1.5

x = 50

50 orders will make both funds equal

Substitute the length of the sides (7 in, 25in n)
into the Pythagorean theorem. Then, find the length of the missing side m
(Please with step by step answer)

Answers

Answer:

with 2 sides, we can assume that the 25 inch side is the hypotenuse.

7^2 + 25^2 = 49 + 625 = 674

674 is NOT a perfect square so we'll make the 25 side as the hypotenuse.

7^2 +n^2  = 625

n^2 = 625 - 49

n^2 = 576

square root (576) = 24

So the 3 sides are

7   24   and 25

Suppose that a number written as a decimal has an infinite number of non-repeating digits after the decimal point. What is this number called?
Oirational
natural
unnatural
rational
Hell yall

Answers

Answer:

Irrational

Step-by-step explanation:

The number is called an irrational number.

These numbers have some distinct properties. The number of numbers after the decimal point is infinite. What this means is that it does not terminate. It keeps on repeating.

Also, these numbers cannot be represented as a ratio of two integers i.e two whole numbers. This is because they keep on going without termination.

Lastly is that these numbers do not repeat after decimal. What I mean by this is that they do not keep repeating a particular number after the decimal point. For example in cases like 2.33333; these are infinite too, but they can be represented by the ratio of two whole numbers and in such cases, they are not irrational in their own respect
