Answer:

about $709 per month

Step-by-step explanation:

Okay, so in order to solve this question, we should follow this formula:

3,000 + 24x \geq 20,000

where 24 is the amount of time we have and x is the variable we are using as to show the unknown amount of money earned per month.

3,000 + 24x \geq 20,000

-3,000               -3,000

24x \geq 17,000

/24           /24

x \geq approximately 709 dollars

so, we substitute x for 709

3,000 + 24(709) \geq 20,000

3,000 + 17,016 \geq 20,000

20,016 \geq 20,000

which is true

Hope this helps :)

Hello!

Let's convert these fractions to decimals.

To convert a fraction to a decimal, simply divide its numerator by its denominator.

3/4 = 0.75

3/8 = 0.375

7/10 = 0.70

1/2 = 0.50

ANSWER:

Since Mary only had 3/8 of her juice, she drank less than half of her juice.

If (x + 2) is a factor of x3 − 6x2 + kx + 10, k =
ch4aika [34]

Answer:

The value of k is -11

Step-by-step explanation:

If (x+2) is a factor of x3 − 6x2 + kx + 10:

Then,

f(x)=x3 − 6x2 + kx + 10

f(-2)=0

f(-2)=(-2)³-6(-2)²+k(-2)+10=0

f(-2)= -8-6(4)-2k+10=0

f(-2)= -8-24-2k+10=0

Solve the like terms:

f(-2)=-2k-22=0

f(-2)=-2k=0+22

-2k=22

k=22/-2

k=-11

Hence the value of k is -11....

Naya [18.7K]

Answer:

b = 9 ft

Step-by-step explanation:

Pythagorean Theorem:

a^2 + b ^2 = c^2

Given:

a = 12

b = ?

c = 15

Plug in values:

12^2 + b^2 = 12^2

Solve for b^2:

b^2 = 15^2 - 12^2

b^2 = 225 - 144

b^2 = 81

Take square root of both sides to find b:

sqrt(b^2) = sqrt(81)

b = 9


Hope this helps! :)
