Omar is driving to Denver. Suppose that the distance to his destination (in miles) is a linear function of his total driving time (in minutes). Omar has 55 miles to his destination after 44 minutes of driving, and he has 41.5 miles to his destination after 62 minutes of driving. How many miles will he have to his destination after 74 minutes of driving?

Answers

Answer:

After 74 minutes of driving, he still has 32.5 miles to his destination.

Step-by-step explanation:

A linear relationship can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we know that a line passes through the points (x₁, y₁) and (x₂, y₂), then we can write the slope as:

a = (y₂ - y₁)/(x₂ - x₁)

Now let's go to the question.

We know that the distance to his destination is a linear function of his total driving time.

We know that he has 55 miles to his destination after 44 minutes of driving. We can write this as the point (44 min, 55mi)

We know that he has 41.5 miles to his destination after 62 minutes of driving, we can write this as (62 min, 41.5mi)

Then the slope of this equation will be:

a = (41.5mi - 55mi)/(62min - 44min) = -0.75 mi/min.

Then the linear equation is something like:

y = (-0.75 mi/min)*x + b

to find the value of b we can use the fact that this line passes through the point (44 min, 55mi)

This means that when x = 44 min, we must have y = 55mi

Then:

55mi = (-0.75 mi/min)*44min + b

55mi + (0.75 mi/min)*44min = b

88mi  =  b

Then the equation is:

y = (-0.75 mi/min)*x + 88mi

Now we want to know how many miles will he have to his destination after 74 minutes of driving, then we need to replace x by 74 min.

y = (-0.75 mi/min)*74min + 88mi

y = 32.5mi

After 74 minutes of driving, he still has 32.5 miles to his destination.

Matt earns $5 for each lawn he does. He wants to earn at least $100. Which inequality represents his situation?

Answers

Answer:

$100 is less than or equal to x

X is greater than or equal to $100.
The reason x is more is because he wants to earn $100 but could always earn more money because more money is always great. So x being the money he earns- could either be MORE or EQUAL to $100.

w=14

Answer:

14 units

Step-by-step explanation:

Given, the area of rectangle = 182 square units

length = 13 units

width = ?

By using the formula to find the area of a rectangle, we have

area of rectangle = length * width

182 = 13 * width

182/13 = width

14 units = width

The circumference of a circular garden is 138.16 feet. What is the radius of the garden? Use 3.14 for it and do not round your answer.
Il feet
?

Answers

Answer:

11 feet

Step-by-step explanation:

The radius of the circular garden is approximately 22 feet.

The formula to calculate the circumference of a circle is given by:

C = 2πr

where C is the circumference and r is the radius of the circle.

We are given the circumference as 138.16 feet, so we can set up the equation:

138.16 = 2 * 3.14 * r

To solve for the radius (r), we can rearrange the equation:

138.16 = 6.28r

Dividing both sides of the equation by 6.28:

138.16 / 6.28 = r

r ≈ 22

Therefore, the radius of the circular garden is approximately 22 feet.

Jimmy invests $2,936 in a retirement account with a fixed annual interest rate of 5% compounded continuously. What will the account balance be after 18 years?

A) $6,599.86

C) $6,534.19

B) $7,221.39

D) $6,869.20

Answers

Answer:

B) $7,221.39

Step-by-step explanation:

Given data

Principal=$2,936

Rate=5%

n=12

Time = 18 years

The expression for compound interest is

A=P(1+r/n)^nt

substitute

A= 2936(1+0.05/12)^12*18

A= 2936(1+0.00416)^12*18

A= 2936(1.00416)^12*18

A= 2936(1.00416)^216

A= 2936*2.45149

A=7197.57464

Hence the approximate amount is B) $7,221.39

Answers

Answer:

Your answer is 8.06.

Step-by-step explanation:

Since you're finding the hypotenuse of the triangle through Pythagorean theorem, you need to use the formula:

a² + b² = c²

Here, you have to remember that x is the same as c in the formula. c is the hypotenuse and x.

a is going to be your smallest leg, so in this case a = 4.

b is going to be your longest leg, so it is b = 7.

Now, you don't know what c yet is so you simply write it as:

4² + 7² = c²

Do the exponents.

16 + 49 = c²

Add.

65 = c²

Now you need to get the exponent away from the c. To do that, all you have to do is square root both sides.

√65 = √c2

Once you do that, you have your answer!

8.0622577483 = c

Now just simplify and you're done :)

8.06
