answer: x=3

Answer: 116 Degrees

Step-by-step explanation:

540 is what the pentagon equals! You add up all of the sides, the square equals 90 degrees because it's a right angle. 121+115+98+90 equals 424. You subtract 540 - 424 and you get 116, which is x! Good luck!

Answer:

1 : 3

Step-by-step explanation:

¼ of the biscuits are chocolate while the rest are plain.

Since a fraction is a part of a whole, 1, then it means that the fraction that are plain is:

1 - ¼ = ¾

Therefore, the ratio of chocolate biscuits to plain biscuits is:

¼ : ¾

To put this in simplest dorm, multiply both sides by 4, we have:

1 : 3

This is the ratio of chocolate biscuits to plain biscuits.

Answer:

300watts

Step-by-step explanation:

Given the power generated by an electrical device modeled by the equation

P(x) = -12x²+120x

The maximum power generated occurs when dP(x)/dx = 0

dP(x)/dx = -24x+120 = 0

-24x + 120 = 0

-24x = -120

x = 120/24

x = 5

Substitute x = 5 into the modeled function to get the maximum power as shown;

Recall that: P(x)=-12x^2+120x

P(5) = -12(5)² + 120(5)

P(5) = -12(25) + 600

P(5) = -300+600

P(5) = 300

Hence the maximum power generated by the circuit is 300watts

-12 + 3 - (10x - 15x + 96)

Step-by-step explanation:

Answer:

Division problems with quotient of 9 and remainder of 5 could include:-

23/2 = 9 + 5/2

32/3 = 9 + 5/3

41/4 = 9 + 5/4

50/4 = 9 + 5/5

But you could justifiably object that more natural forms for the answers would be 11 + 1/2, 10 + 1/3, 10 + 1/4 and 10 , and so you may well prefer such as

59/6 = 9 + 5/6

77/8 = 9 + 5/8  ….. and so on

As you can see the general pattern is (9n + 5)/n = 9 + 5/n

You can now make up your own examples, like 212/23 = 9 + 5/23

Answer:

4

Step-by-step explanation:

(5a^2b^3)(6a^kb) = 30a^6b^4

a^2 * a*k = a^6

a^(2 + k) = a^6

2 + k = 6

k = 4

Answer: 4

The value of k from the equation is k = 4

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

( 5a²b³ ) ( 6a^k )b = 30a⁶b⁴

On simplifying , we get

From the laws of exponents , we get mᵃ×mᵇ = mᵃ⁺ᵇ

So , ( 30a^( 2 + k ) ) b⁴ = 30a⁶b⁴

Divide by 30b⁴ on both sides , we get

a^( 2 + k ) = a⁶

Now , the bases of the exponents are same ,

So , 2 + k = 6

Subtracting 4 on both sides , we get

k = 4

Therefore , the value of k = 4

Hence , the exponential equation is solved

The total money earned by Monique can be written as a expression as 12h + 20.

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

The earning per hour working as lifeguard is $12.

And, the earning from dog city is $20.

Suppose the number of hours worked as lifeguard be h.

Then, the money earned working as lifeguard is 12h.

Now, the expression for total money earned can be given as,

12h + 20

Hence, the expression for the total earning can be given as 12h + 20.

Answer:

The probability is 0.9

Step-by-step explanation:

We start by calculating the density function

That will be;

f(x) = 1/(b-a)

b and a are the extremes

from the question,

a = 15

b = 65

So f(x)

= 1/(65-15) = 1/50 = 0.02

The probability we want to calculate is;

P( x > 20)

The termination point is 65

So the probability will be

(65-20) * 0.02

= 0.9
