pounds less than three times what Dylan weighs. If Cecil weighs the same as the combined weight of Bruce and Alan, what is Cecil's welght in
terms of Dylan's weight (d)?
Complete the steps below to solve this problem and others like it.
Part A
Alan weighs 3 pounds more than twice what Dylan weighs. Write an explession to represent Alan's weight in terms of Dylan's weight.

Answers

Answer 1

Answer:

Step-by-step explanation:

a=2d+3

b=3d-12

c=a+b so

c=2d+3+3d-12

c=5d-9

Answer 2

Answer:

2d + 3

Step-by-step explanation:

Dylan’s weight is d.

Twice Dylan’s weight is 2d.

Three pounds more than twice Dylan’s weight is 2d + 3.

So, the expression for Alan’s weight in terms of Dylan’s weight is 2d + 3.

Use the table below to determine whether f(x) could represent a linear function. If it could write f(x) in the form f(x) = mx +b.

Answers

Answer:

5x-3

Step-by-step explanation:

This is linear because the numbers are changing at a constant rate (of 5)

We can also see that when x=0 y= -3 which means that in our equation

y=mx+b

-3 =b

I said prior that the rate of change is 5 which means that our slope is 5

which means that our equation looks like

Jack's linear speed is (Select ]
feet per minute.

Bob's linear speed is Select !
feet per minute.

Answers

Bob's linear speed is higher than Jack's because the radius of the circle

around which Bob rotates is larger.

Responses:

Jack's linear speed is approximately 377 feet per minuteBob's linear speed is approximately 527.8 feet per minute

What is the relationship between linear speed and angular speed?

Given:

The rotational speed of the merry go round = 6 revolution per minute

Jack's distance from the center = 10 feet

Bob's distance from the center = 14 feet

The angular speed, ω, of the merry-go-round is found as follows;

[tex]\omega = \mathbf{\dfrac{6 \times 2 \cdot \pi}{1 \ minute}} = 12 \cdot \pi \ rad/minute[/tex]Linear speed = ω × r

Which gives;

Jack's linear speed = 12·π rad/min × 10 feet ≈ 377 feet per minuteBob's linear speed = 12·π rad/min × 14 feet ≈ 527.8 feet per minute

Carlos is a member of a gym. He pays a monthly fee plus a per- visit fee. The equation y = 3x + 10 represents the monthly amount Carlos pays for x visits.
if Carlos pays $85 in the last month how many times did he visit the gym?

Answers

Answer:

25 times

Step-by-step explanation:

To find how many times he visited, plug in 85 as y and solve for x:

y = 3x + 10

85 = 3x + 10

75 = 3x

25 = x

So, Carlos visited the gym 25 times

Find the missing length.

Answers

Answer:

Triangle 1 - 4

Triangle 2 - 10

Step-by-step explanation:

To find the missing side lengths of a right triangle, use the Pythagorean Theorem. The Pythagorean Theorem states that: a² + b² = c². In this equation, a and b are legs, and c is the hypotenuse.

Using this to solve triangle 1, you get the equation: a² + 3² = 5² or a² + 9 = 25. To solve for a², you subtract 9 from both sides to get a² = 16. To solve for a, find the square root of 16, which is 4.

Using the Pythagorean Theorem to solve for triangle 2, you get the equation: 6² + 8² = c² or 36 + 64 = c². Add 36 + 64 to get 100 = c². Find the square root of 100 to solve for c. The square root is 10.

Hope it helps!
