Answer 1
X = 100 degrees

This is because the straight angle equals 180 degrees in total so to find the value of x you write the following equation

X + X -20 = 180 degrees
2x -20 = 180 degrees
+20 +20
2x = 200
Divide by 2 on both sides
X = 100

Mrs. Olen wants to join a gym. Francis Lewis Gym charges a new member fee of $150 plus $10 each month. Clintonville Gym charges a new member fee of $50 plus $35 each month.

Answers

Answer:Step-by-step explanation:

a. Let x = number of months

Amount charged by Francis Lewis Gym = 150 + 10x

Amount charged by Clintonville Gym = 50 + 35x

Set each expression equal to the other to generate an equation to use in finding the number of months for which the cost of membership will be the same at both months

150 + 10x = 50 + 35x

Collect like terms

150 - 50 = -10x + 35x

100 = 25x

Divide both sides by 25

100/25 = x

4 = x

Answer: 4 months

b. Substitute x = 2 into each if the expression of the amount charged by each gym. The one that gives the lowest amount should be the one Mrs. Open should should join.

Amount charged by Francis Lewis Gym = 150 + 10x

= 150 + 10(2)

= 150 + 20

= $170

Amount charged by Clintonville Gym = 50 + 35x

= 50 + 35(2)

= 50 + 70

= $120

She should join the Clintonville Gym if she plans to join a gym for 2 months.

Answer: Clintonville Gym

TRUE OR FALSE? The difference between two numbers is (-3). WHICH OF THE EXPRESSIONS COULD REPRESENT THE SUBTRACTION PROBLEM? (HINT: Solve each expression - if it equals (-3) it is TRUE - if it does NOT equal (-3) than it is FALSE) REMEMBER: Change subtraction problem into addition problem before solving. A) -4 - 1

Answers

Answer:

A) True

Step-by-step explanation:

[tex]-4,-1[/tex]

If we subtract the two numbers we get

[tex]-4-(-1)=-4+1=-3[/tex]

It can be seen that subtracting the two numbers changes the sign of one number by which we can algebraically subtract the numbers. Since, the addition of 1 shifts the number towards zero in the number line, the minus sign still remains.

So A)-4 -1 is true.

Step-by-step explanation:

This is a word problem which should be tackled accordingly.

The sum of 48 and itself

= 48+48

= 96

It's half and half of its half

= 48/2 and (48/2)/2

= 24+ 24/2

= 24+12

= 36

Is added to 18

= 96+36+18

= 150

From the description above the entire sum is 150.

You found the correct slope for Line 1, but Line 2 has a slope of (3 - 2)/(6-3) = 1/3.

If 2 lines are parallel, their slopes are the same; perpendicular and their slopes are opposite reciprocals (change the sign of the first slope, then divide 1 by it and you get the perpendicular line's slope). 1/3 is NOT the opposite reciprocal of 3 (because they have the same sign) and 1/3 is NOT equal to 3, so that makes the answer neither.

The slope for Line 3 is (3 - 1)/(1 - (-1)) = 2/2 = 1

The slope of Line 4 is (1 - (-1))/(4 - 2) = 2/2 = 1

1 = 1, so these lines are parallel

The population of a community is known to increase at a rate proportional to the number of people present at time t. The initial population P0 has doubled in 5 years. Suppose it is known that the population is 9,000 after 3 years.

Required:
a, What was the initial population P0?
b. How fast is the population growing at t = 10?

Answers

Step-by-step explanation:

Let the initial population of a community be P0 and the population after time t is P(t).

If the population of a community is known to increase at a rate proportional to the number of people present at time t, this is expressed as:

[tex]P(t) = P_0e^{kt}[/tex]

at t = 5 years, P(t) = 2P0

substitute:

[tex]2P_0 = P_0e^{5k}\\2 = e^{5k}\\ln2 = lne^{5k}\\ln2 = 5k\\k = \frac{ln2}{5}\\k = 0.1386[/tex]

If the population is 9,000 after 3 years

at t = 3, P(t) = 9000

a) Substitute into the formula to get P0

[tex]9000 = P_0e^{0.1386\times 3}\\9000 = P_0e^{0.4158}\\9000 = 1.5156P_0\\P_0 = \frac{9000}{1.5156}\\ P_0 = 5938.24[/tex]

Hence the initial population is approximately 5938.

b) In order to know how fast the population growing at t = 10, we will substitute t = 10 into the formula as shown:

[tex]P(10) = 5938.24e^{0.1386(10)}\\P(10) = 5938.24e^{1.386}\\P(10) = 5938.24(3.9988)\\P(10) = 23,745.97[/tex]

Hence the population of the community after 10 years is approximately 23,746

What is the additive inverse of the polynomial

9xy² + 6x²y -5x

Answers

Answer:

-9xy² - 6x²y + 5x

Step-by-step explanation:

The additive inverse of a polynomial is simply defined as the same polynomial but the difference is that the signs attached to each of the terms will change. This means that positive sign will change to negative while negative sign will change to positive.

Now, we are given the polynomial;

9xy² + 6x²y - 5x

Thus, from earlier description, additive inverse of this polynomial is;

-9xy² - 6x²y + 5x

The volume of air in a balloon is represented by the function v(n) = nr), where r is the radius of the balloon, in


inches. The radius increases with time, in seconds, by the function r(t) = 4,2. Which statements are true?

Answers

Answer:

When V is composed with r, the composite function is [tex]\frac{1}{48} \pi t^{6}[/tex]

When Vr6 shows that the volume is 9724. When the radius is increased to 6 inches.

Step-by-step explanation:

Volume is determined by [tex]cm^{3}[/tex] if the balloon is filled with air its volume will be increased and the composite function will represent the volume of the balloon. The radius of the balloon will rise in seconds. If t seconds are consumed to reach to a radius of 6 inches then the pie function is used to determine the volume.

A bee flies at 10 feet per second directly to a flowerbed from its hive. The bee stays at the

flowerbed for 16 minutes, and then fies directly back to the hive at 8 feet

b. How far is the flowerbed from the hive?

a. Write the equation Leld be the distance of the flowerbed from the hive

(Type an equation Use integers of fractions for any numbers in the equation. Do not simplity)

Answers

Answer:

a. s = [tex]\frac{d}{t}[/tex]

b. 9600 ft

Step-by-step explanation:

In the given question, the motion of the bee involves speed (s), distance (d) and its time of flight (t).

a. The equation required to determine the distance of the flowerbed from the hive/ hive to flowerbed is;

speed = [tex]\frac{distance}{time}[/tex]

i.e s = [tex]\frac{d}{t}[/tex]

b. Given that: the bee flies back at 8 feet per second, and in 20 minutes (1200 seconds);

s = [tex]\frac{d}{t}[/tex]

⇒ d = s x t

       = 8 ft/s x 1200 s

       = 9600 ft

The flowerbed is 9600 feet from the hive.

Step-by-step explanation:

the number is x

2x = 4x - - 18

2x = 4x + 18

-2x = 18

x = -9

Answer:

-9

Step-by-step explanation:

Let's solve your equation step-by-step.

2x=4x−(−18)

Step 1: Simplify both sides of the equation.

2x=4x+18

Step 2: Subtract 4x from both sides.

2x−4x=4x+18−4x

−2x=18

Step 3: Divide both sides by -2.

−2x/−2

= 18 /−2 x
