Monster Mike's truck decelerates from 72 m/s to 0 m/s in 6 seconds. What is his rate of deceleration?

Answers

Answer:

this may be wrond but I think it is -12 m/s

Step-by-step explanation:

[tex]72/6=12[/tex]

The requried rate of deceleration of Monster Mike's truck is -12 m/s².

What is speed?

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Here,
The rate of deceleration of Monster Mike's truck can be calculated using the following formula,

Acceleration = (Final Velocity - Initial Velocity) / Time

Final Velocity = 0 m/s (since the truck comes to a stop)

Initial Velocity = 72 m/s

Time = 6 seconds

Substituting the given values into the formula,

Acceleration = (0 m/s - 72 m/s) / 6 s

Acceleration = -12 m/s²

Therefore, the rate of deceleration of Monster Mike's truck is -12 m/s². The negative sign indicates that the acceleration is in the opposite direction to the initial velocity of the truck.

Answers

y-1=-1/8(x+2) You just plug your points into the formula

Hey there! :) How are you? Explanation: So basically the cook has 3 1/2 cups of flour which is 7/2 as a improper fraction. The recipe calls for 3 2/3 cups of flour which is 11/3. So next we need to find a common denominator. 2 and 3 both have 6 in common, so7/2=21/6 and 11/3=22/6. The final step is 22/6-21/6= 1/6.

A Cab charges $1.75 for the flat fee and $0.25 for each mile. Write and solve an inequality to determine how many miles Eddies can travel if he has $15 to spend

Answers

1.75 + 0.25x ≤ 15
where x is equal the number of miles.

The key to solving an inequality is just temporarily making the ≤ symbol a =. Then solve for x like any other algebraic equation. Once you find the value of x, you will have solved the inequality. Make sure to add back the ≤ when you are done. 

15 - 1.75 = 13.25
13.25/0.25 = x 
x = 53
add back the ≤
x ≤ 53
This means Eddies can travel up to 53 miles with his $15.

You would combine like terms, so it would become 12x +12=180 Then you would subtract 12 from both sides so that the x is on one side and the just plain numbers are on the other side. So your equation now is 12x=168 You then at this point would divide both sides by 12 to get the x alone. Your final answer then would be x=14

C) write the equation of the line in slope-intercept form. Show your work.
A,B,C are all parts of the question that have to be answered.

Answers

you're answer should be (B) hopes it helps.
Part A:

Slope of line is given by vertical distance ÷ horizontal distance

Let (8, 9) be (x₁, y₂) and (-2, 4) be (x₂, y₂)
The vertical distance is y₂ - y₁ = 4 - 9 = -5
The horizontal distance is x₂ - x₁ = -2 - 8 = -10

slope of the line = -5 ÷ -10 = 0.5
---------------------------------------------------------------------------------------------------------------

Part B

The point-slope form is given by
(y - y₁) = m (x - x₁)

We have the gradient, m = 0.5
(x₁, y₁) = (8, 9) ⇒ You can also use the other coordinate (-2, 4)
Substitute these value into the form, we have

(y - 9) = 0.5 (x - 8)
----------------------------------------------------------------------------------------------------------------

Part C

The slope-intercept form is given by the equation
y = mx + c

Where m is the slope gradient and c is the point where the line intercepts the y-axis. We don't have the value of c at the moment but we can find out by simplifying the equation in part B

y - 9 = 0.5 (x - 8) ⇒ Multiplying out the bracket
y - 9 = 0.5x - 4
y = 0.5x - 4 + 9
y = 0.5x + 5 ⇒ This the slope-intercept form

Let's try out the first. 7 * 7 is 49 and 5 * 9 is 45. 49 - 45 is 4. 4 < 28. Therefore, A is out. 7 * -1 is -7 and 5 * -7 is -35. -7 - (-35) is 28. 28 = 28. Score! But wait. 7 * 4 is 28 and 5 * 10 us 50. 28 - 50 is -22. C is out. 7 * -6 is -42 and 5 * -14 is -70. -42 - (-70) is also 28. 28 = 28. You have two answers. They are B and D.

a number q multiplied by 1/4 is greater than -16

Answers

In number form this is:
q · 1/4 > -16
To get rid of the fraction, multiply both sides by 4 to get the answer:
q > -64

Final answer:

The student is dealing with an inequality where a number q is multiplied by [tex]\frac{1}{4}[/tex] and needs to be greater than -16. Upon solving, the result is that q must be greater than -64.

Explanation:

The student is asking about an inequality in mathematics where a number q multiplied by [tex]\frac{1}{4}[/tex] must be greater than -16. To solve this, we set up the inequality as follows:

[tex]\frac{1}{4}[/tex] × q > -16

When solving for q, you would multiply both sides of the inequality by 4 to isolate q:

q > -16 × 4

q > -64

Therefore, the value of q must be greater than -64 to satisfy the inequality.

how do you solve
x+3/5-3x/10=7

Answers

Heyo!

x+3/5-3x/10=7

Multiply both sides of the equation by 10

10x +6 - 3x = 70

Collect the terms

7x + 6 = 70

Move constant to the right side and
change its sign

7x = 70 -6

Subtract the numbers

7x = 64

Divide both sides by seven

x = 64/7

3x - 4y =7 solve for y

This is a literal equation in which you need to isolate the variable 'y'

Answers

3x - 4y = 7...subtract 3x from both sides
-4y = -3x + 7...divide both sides by -4
y = 3/4x - 7/4 <==

The solution of the given equation 3x - 4y = 7 for the value of y in terms of variable x is given by y = (3x - 7) / 4.

To solve for 'y' in the equation 3x - 4y = 7, we need to isolate 'y' on one side of the equation. Here's how you can do it step by step:

Move the term containing 'y' to the other side of the equation by adding 4y to both sides:

3x - 4y + 4y = 7 + 4y

Simplify the equation:

3x = 7 + 4y

Now, we want to isolate 'y' on one side. Start by moving the constant term (7) to the other side by subtracting 7 from both sides:

3x - 7 = 7 + 4y - 7

Simplify the equation:

3x - 7 = 4y

Finally, to get 'y' alone, divide both sides by 4:

(3x - 7) / 4 = y

Therefore, the solution for 'y' in terms of variable 'x' is y = (3x - 7) / 4.

a tin can collecting money on a store counter for the holiday season contains 15.80 dollars in quarters and dimes. if there are a total of 74 coins how many of each coins are in the tin

Answers

Final answer:

To find out how many quarters and dimes are in the tin, we set up a system of equations based on the total value and total number of coins. Solving these equations reveals that the tin contains 56 quarters and 18 dimes.

Explanation:

The student is asking for help with a system of equations problem that involves quarters and dimes that add up to $15.80, with a total of 74 coins in the tin. To solve this, we set up two equations: one for the total amount of money (1) and the other for the total number of coins (2).

Let's let Q be the number of quarters and D be the number of dimes. Therefore:

0.25Q + 0.10D = $15.80 (because quarters are $0.25 each and dimes are $0.10 each)Q + D = 74 (total number of coins)

From equation (2), we can express D in terms of Q as D = 74 - Q. Substituting this into equation (1) gives us:

0.25Q + 0.10(74 - Q) = $15.80

This simplifies to:

0.25Q + 7.4 - 0.10Q = $15.80

0.15Q = $15.80 - 7.4

0.15Q = $8.40

Dividing both sides by 0.15 gives:

Q = $8.40 / 0.15

Q = 56 quarters

Substitute Q (56) back into equation (2) to find D:

D = 74 - 56

D = 18 dimes

Therefore, there are 56 quarters and 18 dimes in the tin.
