Is 90 a perfect cube

Answer:

13%

Step-by-step explanation:

Increase = (New Number - Old Number) / Old Number

(130 - 115) / 115

15/115 = 0.130434783.

0.130434783 * 100 (to get the percentage) = 13.0%

50 percent is c.x=5,y=2.

Step-by-step explanation:

m∠ABC = [tex]\frac{1}{2}[/tex] m∠AOC = 54°

Answer: 54°

because ∠ADC is the  angle at the center of the arc AC and ∠ABC  is the inscribed angle of the arc AC

=> m∠ABC = 1/2. m∠ADC = 108/2 = 54°

Answer:

Step-by-step explanation:

The factors of 84 are: [tex]\pm: 1, 84, 2, 42, 3, 28, 4, 21, 6, 14, 7, 12 ...[/tex]

7 and 12 can make 5. Since 84 is negative and 5 is positive, the larger number of the two must be the positive number in the factorization. In this case, it is

Answer:

Here's the answer

Step-by-step explanation

y= 18x+9.20

Answer:

y = -23x + 85

Step-by-step explanation:

for an equation to be parallel to another, they must have the same slope. So plugging in (4, -7) we get -7 = -23(4) + P. P being the new y intercept we must find. Now simple algebra add -23(4) = -92 to both sides and we get 85 = P. Plug in to y = mx + b and we get

y = -23x + 85

Answer:

11

Step-by-step explanation:

Substitute 4 for x

2(4) +3

Answer:

11

Step-by-step explanation:

F(x) = 2x+3 is just a function, so if you replace one of the "x" with 4 you have to replace the other one so it just becomes

F(4) = 2(4) + 3 then you do 2(4) = 8 then add 3 to it and it gets you 11.

Answer:

180-43=137....................

Answer:

182

Step-by-step explanation:

take 520 and multiply by 0.35

The number of female students participated in a chess tournament is 338.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, 520 students participating in a chess tournament, 35% were male.

Number of male students = 35% of 520

35/100 ×520

= 0.35×520

= 182

So, the number of female students

= 520-182

= 338

Therefore, the number of female students participated in a chess tournament is 338.

Answer:

(1 + 3i)(1 - 3i)

Step-by-step explanation:

The product of a complex number and its conjugate produce a real number.

given a ± bi the conjugate is a ∓ bi ← where a and b are real, then

(a + bi)(a - bi)

= a² - b² ← a real number

The only pair of conjugate complex numbers in the list is

(1 + 3i)(1 - 3i)

The pair of complex numbers that has a real-number product is:

(1 + 3) (1-3) = -8

Option C is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

For a pair of complex numbers to have a real-number product, their imaginary parts must cancel out when the product is expanded.

Let's expand each pair of complex numbers and see which one has a

real-number product:

(1 + 3) x (61) = 61 + 183i

This product has a non-zero imaginary part, so it is not a real number.

(1 + 3) x (2-3) = -5 + 5i

This product has a non-zero imaginary part, so it is not a real number.

(1 + 3) x (1-3) = -8

This product has no imaginary part, so it is a real number.

(1 + 3) x (31) = 124 + 124i

This product has a non-zero imaginary part, so it is not a real number.

Therefore,

The pair of complex numbers that has a real-number product is:

(1 + 3) (1-3) = -8

Answer: (2,2)

Step-by-step explanation:

The solution of the system of equations is the intersection point, or the point where both lines meet. Looking at the graph, we see that the blue and red line meet at (2,2). That means the solution is (2,2).

We can also solve this algebraically. Since we are given that y=x, we can plug that into the equation and solve.

y+2y=6       [combine like terms]

3y=6            [divide both sides by 3]

y=2

Since we are told that y=x, we know that x is also 2. This tells us that the solution is also (2,2).

Answer: x=7 or undefined

Step-by-step explanation:

We can't write x=7 in slope intercept form, since it doesn't have an actual slope or y-intercept. You could put undefined, since the slope is undefined.

Answer:

Step-by-step explanation:

6 of the 10 bars are shaded, so the shaded area is 6/10 of the whole.

"Six tenths" as a decimal is 0.6, that is, a number with 6 in the tenths place.

To convert the number to a percent, multiply either the fraction or the decimal by 100%.

  0.6 × 100% = 60%
