Answer:

0.25

Step-by-step explanation:

Half of a tenth in 5 hundredths.

To find the midpoint of 0.2 and 0.3, think of it as 20 and 30.

What would be the midpoint of 20 and 30? 25.

Therefore, 0.25 would be the midpoint of 0.2 and 0.3

Answer:

The domain is -11 < x < 4 or in interval notation it is (-11, 4).

Step-by-step explanation:

The domain is the set of possible values of x.

Here the open circles at each end mean that these values are not included.

The correct reason for each step in the solution of the equation would be as follows:

12 − 5x + 6x = 4 - Given

12 + x = 4 - Combine Like Terms

Step-by-step explanation:

The amount of change is:

The time difference in years:

The annual rate of change is the ratio of the difference in amount to the time difference:

Step-by-step explanation:

Solution

Number of rows = number of columns = r

:: r × r = 1296

In other words,

r square 2 = 1296

now solve in prime factorization,

the answer is 36

The question is an illustration of related rates.

The rate of change between you and the ball is 0.01 rad per second

I added an attachment to illustrate the given parameters.

The representations on the attachment are:

[tex]\mathbf{x = 100\ m}[/tex]

[tex]\mathbf{\frac{dy}{dt} = 2\ ms^{-1}}[/tex] ---- the rate

[tex]\mathbf{\theta = \frac{\pi}{4}}[/tex]

First, we calculate the vertical distance (y) using tangent ratio

[tex]\mathbf{\tan(\theta) = \frac{y}{x}}[/tex]

Substitute 100 for x

[tex]\mathbf{y = 100\tan(\theta) }[/tex]

[tex]\mathbf{\tan(\theta) = \frac{y}{100}}[/tex]

Differentiate both sides with respect to time (t)

[tex]\mathbf{ \sec^2(\theta) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot \frac{dy}{dt}}[/tex]

Substitute values for the rates and [tex]\mathbf{\theta }[/tex]

[tex]\mathbf{ \sec^2(\pi/4) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]

This gives

[tex]\mathbf{ (\sqrt 2)^2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]

[tex]\mathbf{ 2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]

Divide both sides by 2

[tex]\mathbf{ \frac{d\theta}{dt} = \frac{1}{100} }[/tex]

[tex]\mathbf{ \frac{d\theta}{dt} = 0.01 }[/tex]

Hence, the rate of change between you and the ball is 0.01 rad per second

Step-by-step explanation:

Answer:

b = c/3 + 2/3

Step-by-step explanation:

3b - 4/2 = c

the goal is to have b all by itself on one side of the equals sign.

start by moving the fraction over to where c is by adding.

3b = c + 4/2

adding -4/2 and +4/2 together makes it a 0 on the b side so there's no need to write anything in that space anymore.

Now 3b are next to each other which means they are multiplying. To move 3 we need to do the opposite (divide by 3 on both sides of the equal sign)

b = c/3 + 2/3

notice I divided both c and 4/2 by 3. 4/2 = 2 so I changed it to 2, then divided by 3

Answer:

b

Answer:

16 times

Step-by-step explanation:

Membership cost:

C = 135 + 2x

Non-members:

C = 11x

____

135 + 2x = 11x

135 = 9x

x = 15

The cost would be the same after renting 15 times, so after 16 times the cost would be cheaper for a member.

Step-by-step explanation:

2x+15 = 5x-43

- Add 43 to both sides

2x+58 = 5x

- Subtract 2x from each side

58 = 3x

- Divide by 3

The interest earned in five years is $1400.

Simple interest is interest calculated on the principal portion of a loan or the original contribution to a saving account.

A = P(1 + rt)

Where,

A is the final amount

P is the initial principal balance

r is the annual interest rate

t is time(in years)

According to the given question

We have

Initial Principal balance, P = $7000

Time, t = 5years

Annual interest rate, r = 4% = 0.04

Therefore, the amount in five years is given by

A =  7000(1 + 0.04(5))

A = 7000(1 + 0.2)

A = 7000(1.2)

A = $8400

Now, the interest earned in five years

S.I = A - P

⇒ S.I = $8400 - $7000

⇒ S.I = $1400

Hence, the interest earned in five years is $1400.

The percentage error in the deer population is 17%

Actual population = 21300

Estimated population = 17600

The percentage error will be calculated by subtracting the estimated population from the actual population and then dividing the result. This will be:

= (Actual population - Estimated population) / Actual population × 100

= (21300 - 17600) / 21300 × 100

= 3700/21300 × 100

= 0.17 × 100

= 17%

Therefore, the percentage error in the deer population is 17%

Answer:

1.5 pounds more.

Step-by-step explanation:

3.75 - 2.25

= 1.50.

Answer:

1.50 pounds

Step-by-step explanation:

Paula orders a macaroni salad and coleslaw each weighing 3.75 and 2.25 pounds respectively

so, to find how many more pounds of macaroni salad than coleslaw we do,

3.75-2.25=1.50

therefore,  macaroni salad has 1.50 pounds more than coleslaw.
