Answer: x ≤ 120

Step-by-step explanation: To get x by itself in this inequality, since it's being divided by -6, we must multiply both sides by -6 just like we would if we were solving an equation.

But here is the trick you have to

watch out for with inequalities.

When you multiply or divide both sides of an inequality by a

negative, you must switch the direction of the inequality sign.

So our second step in this problem reads x ≤ 120.

Please give this idea your full attention. Even the most advanced algebra students will sometimes forget to switch the direction of the inequality sign when multiplying or dividing both sides of an inequality by a negative.

Answer with Step-by-step explanation:

a.If the circle has circumference of [tex]6\pi[/tex] in,then it has a diameter of 3 in.

Circumference of circle=[tex]6\pi[/tex]in

We know that

Circumference of circle=[tex]2\pi r[/tex]

Using the formula

[tex]6\pi=2\pi r[/tex]

[tex]r=\frac{6\pi}{2\pi}=3[/tex]in

Diameter of circle=[tex]2\times 3=6[/tex]in

It is false.

b.f the circle has diameter of 2 inches,then it has a circumference of 6.28 in.

Diameter,d=2 in

Circumference of circle=[tex]\pi d=3.14 \times 2=6.28[/tex]in

It is true.

c.If the circle has a circumference of [tex]2\pi[/tex]in then it has an area [tex]\pi[/tex] square inches.

Circumference=[tex]2\pi[/tex]in

[tex]2\pi r=2\pi[/tex]

[tex]r=\frac{2\pi}{2\pi}=1[/tex]in

Area of circle=[tex]\pi r^2=\pi(1)^2=\pi in^2[/tex]

It is true.

d.If the circle has a circumference of [tex]\pi[/tex]in then it has an area [tex]0.5\pi[/tex] square inches.

Circumference=[tex]\pi[/tex]in

[tex]2\pi r=\pi[/tex]

[tex]r=\frac{\pi}{2\pi}=\frac{1}{2}in[/tex]

Area of circle=[tex]\pi(\frac{1}{2})^2=0.25\pi in^2[/tex]

It is not true.

e.If the circle has a radius of 1.5 inches,then it has an area of 7.065 square inches.

Radius,r=1.5 in

Area of circle=[tex]3.14\times (1.5)^2=7.065in^2[/tex]

It is true.

Answer:

16/25

Step-by-step explanation:

We have 4 red marbles and a total of 4 + 1 = 5 marbles.

Probability is simply (# times a specific event can occur) / (# times any event can occur).

Here, the probability of drawing a red marble is: 4/5 (because there are 4 red marbles to choose from and a total of 5 marbles to choose from).

We replace the marble afterward, so the probability that the second pick is also red would still be 4/5.

Then, multiply the two fractions together: (4/5) * (4/5) = 16/25.

Hope this helps!

Step-by-step explanation:

Given that 40 people liked cats, that is 20 women and 20 men

Then the dual bar representing 20 is made up of 4 frequency bars

Then each frequency bar represents 20 ÷ 4 = 5 people

Thus

dogs = 25 (men) + 30 (women) = 55

hamster = 15 ( men) + 5(women) = 20

other = 10(men) + 15(women) = 25

A total of 40 + 55 + 20 + 25 = 140

Answer:

mean = 24

Step-by-step explanation:

In a stem-and-leaf plot, each leaf represents a number or piece of data.

Each the leaf will only show the last digit of the number, and the stem will have the rest.

Examples:

stem value of 1 with a leaf value of 2 = 12

a stem value of 3 with a leaf value of 0 = 30

So, this is your plot:

Stems| Leaves

  1      |   2  3  5

  2     |   8  8

  3     |   0

  4     |   2

Your data is 12, 13, 15, 28, 28, 30, 42.

Add up all these numbers and divide by the number of leaves.

Sum of data = 12 + 13 + 15 + 28 + 28 + 30 + 42 = 168

Number of leaves = 7

168 ÷ 7 = 24

∴ The mean is the values in the stem-and-leaf plot is 24.

Answer:

- 1364

Step-by-step explanation:

The n th term of a geometric series is

[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]

where a is the first term and r the common ratio

4[tex](-2)^{n-1}[/tex] ← is an n th term

with a = 4 and r = - 2

The sum to n terms of a geometric series is

[tex]S_{n}[/tex] = [tex]\frac{a(r^{n}-1) }{r-1}[/tex], thus

[tex]S_{10}[/tex] = [tex]\frac{4((-2)^{10}-1) }{-2-1}[/tex]

      = [tex]\frac{4(1024-1)}{-2-1}[/tex]

      = [tex]\frac{4(1023)}{-3}[/tex]

      = [tex]\frac{4092}{-3}[/tex]

      = - 1364

Answer:

Therefore 2000 units are sold when $1000 is spent on advertising.

Step-by-step explanation:

Given that,

The equation of a model for consumer's response to advertising is

N(a)=2000+500 ln(a)

where a is the amount spent on advertising, in thousand of dollars and a≥1,N(a) is the amount of units sold.

$1000 is spent on advertising.

Since a is in thousand of dollars.

∴a=1

Now plug a=1 in the given model

N(a)=2000+500 ln(1)

⇒N(a)=2000+500×0       [ ∵ln(1)=0 ]

⇒N(a) = 2000

Therefore 2000 units are sold when $1000 is spent on advertising.

The equation a = 100 + 75d represents Maria's  account balance.

Step-by-step explanation:

Given that,

You need to find the equation to represent Maria's  account balance, a after she has  completed d deposits.

Therefore, the equation for the total account balance can be framed as the sum of the initial deposit and amount deposited after that.

To find the amount that was deposited after the initial deposit :

⇒ $75 × number of times Maria deposited.

⇒ 75 × d

The equation is written as,

⇒ a = 100 + 75d

Hence the equation a = 100 + 75d represents Maria's  account balance.

Answer:

  D) x² − xy − 100 = 0

Step-by-step explanation:

You want an expression for "An unknown integer, multiplied by the unknown integer minus a different unknown integer, equals 100."

Let x represent the unknown integer, and y represent the different unknown integer. Their difference will be (x -y). When that is multiplied by x and the result equal to 100, we have ...

  x(x -y) = 100

Eliminating parentheses using the distributive property, we have ...

  x·x -x·y = 100

  x² -xy = 100

Subtracting 100 gives an expression equal to zero:

  x² -xy -100 = 0 . . . . . . . matches choice D

Answer:

40% decrease

Step-by-step explanation:

Say the percent decrease is x%. Then, we can write the equation:

65 - x% * 65 = 39

Notice that 65 is a common factor of both terms on the left, so factor that out:

65 * (1 - x%) = 39

Divide by 65 on both sides:

1 - x% = 0.6

Subtract 0.6 from and add x% to both sides:

x% = 0.4

Remember that % simply means "out of 100", so x% = x/100:

x/100 = 0.4

Multiply by 100:

x = 40

So the percentage decrease is 40%, or the percent increase is -40% (whichever way the question asks).

Hope this helps!

Answer:

p = 40%

Step-by-step explanation:

65 - p%65 = 39

65 - 65p/100 = 39

6500 - 65p = 3900

6500 - 3900 = 65p

65p = 2600

p = 2600 : 65

p = 40%

Answer:

She travels 30 miles for work.

Given,

Total time = 45 minutes

Speed on small world = 32mph

Time on small world = 1/2 hour

Distance = Speed * time =

Distance on small world = 16 miles

Speed on small road = 56mph

Time on small road = 1/4 hour

Distance on small road =

Distance on small road = 14 miles

Total distance = Distance on small world + Distance on small road

Total distance = 16+14= 30 miles

She travels 30 miles for work.

Keywords: Distance, speed

Step-by-step explanation:

Final answer:

Carol travels 12 miles on the small road and 28 miles on the highway, totaling 40 miles to get to work.

Explanation:

The question asks us to calculate the total distance Carol travels to work using two different speeds on two different roads. To solve this problem, we use the formula d = vt, where d represents distance, v is velocity (or speed), and t is time.

On the small road, Carol drives at 24 miles per hour for half an hour (0.5 hours). Therefore, the distance traveled on the small road is:

d = (24 miles/hour)(0.5 hours) = 12 miles

On the highway, she drives at 56 miles per hour for half an hour (0.5 hours) as well. The distance traveled on the highway is:

d = (56 miles/hour)(0.5 hours) = 28 miles

To find the total distance, we add the distances from both roads:

Total distance = 12 miles + 28 miles = 40 miles

Carol travels a total of 40 miles to get to work.
