How will you write 7^5 as a multiplication expression?
A.
7 * 5
B.
7*7*777
C.
5 x 5 x 5 x 5 x 5 x 5 x 5

ANSWER

C. sin 126°

EXPLANATION

-576° is coterminal with ±216,±144.

Therefore

cos (-576°)=cos(±216°)=cos(±144°)

The principal angle for -576° is 36° .

Since the terminal side of -576° is in the second quadrant and the cosine ratio is negative in the second quadrant,

cos (-576°)=-cos (±36°)

Also from complementary angles

cos (-576°)=-cos (36°)=-sin (90-36)=-sin(54°)

Answer: The correct answer is inverted

Step-by-step explanation:

Question 4? is (maybe) C because a square and a rectangle's diagonals are perpendicular.

Question 5- True

Question 6- False, a square is always a rombi but a rombi isn't always a square.

Question 7- True

Question 8- True, because if they didn' then they wouldn't equal 360 degrees and the sum of a trapezoids interior angles has to add up to 360 degrees.

Answer:

see explanation

Step-by-step explanation:

Given

Ax - bx - y = z ( add y to both sides )

Ax - bx = z + y ← factor out x from both terms on the left side

x(A - b) = z + y ← divide both sides by (A - b)

x = [tex]\frac{z+y}{A-b}[/tex]

ANSWER

D. 18 m^2

EXPLANATION

The area of a kite is half the product of the diagonals.

The diagonals of the kite are

3+3=6m

and

2+4=6m

The area of the kite

[tex] = \frac{1}{2} \times 6 \times 6[/tex]

[tex] = 3 \times 6[/tex]

[tex] = 18 {m}^{2} [/tex]

The correct answer is D.

The area of kite using the diagonal length 6m and 6 m is 18 m².

Thus, option (d) is correct.

Given:

length of diagonal 1 = 3+ 3 = 6 m

length of diagonal 2 = 2+ 4 = 6 m

Using the formula of Area of Kite

[tex]{\text} Area of kite[/tex] = [tex]\dfrac{1}{2} *[/tex] [tex]{\text} product \; of \;diagonal[/tex]

Now, substituting the values of diagonal into the formula as

[tex]{\text} Area of kite[/tex] = [tex]\dfrac{1}{2} *[/tex] [tex]{\text} (6 * 6)[/tex]

                   = [tex]\dfrac{1}{2} *[/tex] [tex]{\text} (36)[/tex]

                   = 18 m²

Thus, the area is 18 m².

Answer:

The amount after three years is $12831.8

Step-by-step explanation:

* Lets revise the compound interest

- The formula for compound interest is  A = P (1 + r/n)^(nt)

 Where:

# A = the value of the investment with interest

# P = the initial investment amount  

# r = the annual interest rate (decimal)

# n = the number of times that interest is compounded per unit t

# t = the time the money is invested

* Now lets solve the problem

∵ The initial amount is $9000

∴ P = $9000

∵ The rate is 12%

∴ r = 12/100 = 0.12

∵ The interest is compound quarterly

∴ n = 4

∵ The money invested for 3 years

∴ t = 3

∵ A = P (1 + r/n)^(nt)

∴ A = 9000(1 + 0.12/4)^(4×3)

∴ A = 9000(1 + 0.03)^12

∴ A = 9000(1.03)^12 = $12831.8

Answer:

4 inches

Step-by-step explanation:

If you divide 18 by 6, the answer is three, so it is scaled down 3x.

So, you have to divide 12 by 3, and the answer is 4.

Answer: 4 Inches

Step-by-step explanation: The rectangle on the left shows that the length is 18 inches and the height is 12 inches. Now, to find the height on the right, First we must realize what changed has been made from the left to the right. We know that our length has decreased to 6 inches from 18. 18 can be divided by 3 and that will give us the quotient of 6. Now, we must divide our height on our original rectangle by 3 as well. Once we divide, our new height of our rectangle also known as X will be 4 Inches Long.

Step-by-step explanation:

.......

Final answer:

The probabilities are matched as follows: A-24%, B-76%, C-19%, and D-25%. These are calculated based on the total number of balls of each color and the fraction that are labeled to win a prize.

Explanation:

The question provides a scenario where there are 24 yellow balls and 76 red balls in a box, and one-fourth of each color are labeled "Win a prize." We are asked to match descriptions of probabilities with their corresponding percent values.

A: Probability that a randomly selected ball labeled "Win a prize" is yellow = (1/4 * 24) / ((1/4 * 24) + (1/4 * 76)) * 100 = 6 / (6 + 19) * 100 = 24%.

B: Probability that a randomly selected ball labeled "Win a prize" is red = (1/4 * 76) / ((1/4 * 24) + (1/4 * 76)) * 100 = 19 / (6 + 19) * 100 = 76%.

C: Probability that a randomly selected ball is labeled "Win a prize" and is red = (1/4 * 76) / 100 = 19%.

D: Probability that a randomly selected yellow ball is labeled "Win a prize" = (1/4 * 24) / 24 * 100 = 25%.

Answer:

Step-by-step explanation:

The formula of a volume of a cylinder:

[tex]V=\pi r^2H[/tex]

r - radius

H - height

We have r = 6cm and H = 8cm. Substitute:

[tex]V=\pi(6^2)(8)=\pi(36)(8)=288\pi\ cm^3[/tex]

[tex]\pi\approx3.14\to V\approx(288)(3.14)=904.32\ cm^3[/tex]

Answer:

904.32 cm³

Step-by-step explanation:

The volume (V) of a cylinder is calculated using the formula

V = πr²h ( r is the radius of the base and h the height )

here r = 6 and h = 8, so

V = 3.14 × 6² × 8

   = 3.14 × 36 × 8 ≈ 904.32 cm³

Answer:8>4n=6 or 8>4+n=6

Step-by-step explanation:

Let's solve the equation step by step. The problem statement can be translated into a mathematical equation:
"Eight more than the product of a number and 4 is equal to 6."
Let x be the number we are looking for. When the problem says "the product of a number and 4," we can express this as 4 * x or 4x. The phrase "eight more than" implies we are to add 8 to the product of the number and 4, making the expression 4x + 8. According to the statement, this expression is equal to 6. Thus, we write the equation as:
4x + 8 = 6
To find the value of x, we will follow these steps:
1. Subtract 8 from both sides of the equation to isolate the term with x on one side.
4x + 8 - 8 = 6 - 8
This simplifies to:
4x = -2
2. Divide both sides of the equation by 4 to solve for x.
4x / 4 = -2 / 4
This simplifies to:
x = -1/2
So the number we were looking for, represented as x, is -1/2.

Answer:

2.16 * (10^-5).

Step-by-step explanation:

5 = -log H+

5 = log (1 / H+)

1/ H+ = 10^5

H+ = 10^-5

In a similar fashion  the other brand has H+ of 10^-4.5.

So the difference in hydrogen ion concentration =  10^(-4.5) - 10^(-5)

= 2.16 * (10^-5).

2.16 × 10⁻⁵ is the  difference in the concentration of hydrogen ions between the two brands of vinegar.

pH is a numerical indicator of how acidic or basic aqueous and other liquid solutions are. The phrase, which is frequently used in biology, agronomy, and chemistry, converts the hydrogen ion concentration, which typically ranges between 1 and 1014 gram-equivalents per litre, into numbers ranging from 0 to 14.

The hydrogen ion concentration in pure water, which has a pH of 7, is 107 gram-equivalents per litre, making it neutral (neither acidic or alkaline). A solution having a pH below 7 is referred to as acidic, and one with a pH over 7 is referred to as basic, or alkaline.

5 = -log H+

5 = log (1 / H+)

1/ H+ = 10^5

H+ = 10^-5

difference=  10^(-4.5) - 10^(-5)

               = 2.16 × 10⁻⁵

Therefore, 2.16 × 10⁻⁵ is the  difference in the concentration of hydrogen ions between the two brands of vinegar.

the correct answer is x = 3x - 5

First you must have the quadratic equal to zero. In order to do this you must subtract 7 to both sides

x^2 + 20x + (100 - 7) = 7 - 7

x^2 + 20x + 93 = 0

Now you must find two numbers who's sum equals 20 and their multiplication equal 93

The expression that is 444 times as large as the expression 34 - 15 is (4 x 34) - 15.

Explanation:

To find the expression that is 444 times as large as the expression 34 - 15, we need to multiply the expression by 444. The correct expression is option C, which is (4 x 34) - 15. Let's break it down:

First, we perform the multiplication: 4 x 34 = 136.

Then, we subtract 15 from the result: 136 - 15 = 121.

Therefore, the expression (4 x 34) - 15 is 444 times as large as the expression 34 - 15.

Answer:

Step-by-step explanation:

The perimeter will also be halved:  (1/2)(20) = 10.

Example:  a rectangle of length 14 ft and width 8 ft has perimeter P = 2(14 ft) + 2(8 ft), or 28 ft + 16 ft = 44 ft.

If we halve the length and width, we get 7 ft and 4 ft, and the P is

2(7 ft) + 2(4 ft) = 14 ft + 8 ft = 22 ft, which is half of the original perimeter 44.
