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.

Noya needs to determine the number of books that will fit into a box. If the box has a length of 18 inches and each book is 2/9 of an inch thick, which expression can be used to determine the number of books that will fit into the box?

Answers

2/9 x = 18; If the total amount of space is 18 inches, and each book is 2/9ths of an inch thick, you have to use x to figure out the missing value of how many books will fit
- First  we know that each book is 2/9 inch thick
- The total  length of the box is 18 inches
- And we can fill the box with x Amounts of 2/9 inch books as long as the total  length DO NOT SURPASS 18 inches

So, the expression would be

[tex]2/9 x \leq 18[/tex]

In which x is the total number of books


help...? heres the question:



kayla says that dividing by 5/6 is the same as dividing by 5, then multiplying by 6. is she correct? why?

Answers

Having 5/6 means that, since the 6 is in the denominator (the bottom number or the number to the right of the /), you divide by 6. Next, since 5 is on the top or to the left of the /, you multiply 5. As that does not match up with Kayla's answer, she is incorrect.

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.

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.

At the beginning, you begin with one whole that's been split into 25 pieces, or 25ths. Before you cover any of them up, you still have all 25, so you have 25 25ths, or, as a fraction, [tex] \frac{25}{25} [/tex]. Next, you take away 3 of those 25ths, or [tex] \frac{3}{25} [/tex], which leaves you with [tex] \frac{25-3}{25} [/tex], or [tex] \frac{22}{25} [/tex].

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.

the third equation is correct!

let x be the number, 

3 times the number would be: 3x

increased by 11 would be: + 11

so its 3x+11=17!

Hope this helps!

(8x+1)+(4x+11)=180°
solve for x

Answers

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

A coffee pot contains 1 1/2 quarts of coffee after Tony pours an equal amount of coffee to cups 3 1/2 cups of coffee Remain the pot how much coffee did Tony pour into each cup

Answers

x = 1 1/4 cups

x = 1.25 cup

Tonya poured 1 1/4 cups into each cup.

Tony poured a total of 2 1/2 cups of coffee into an unspecified number of cups.

To solve this problem, we first need to understand the different units of measurement being used and convert them appropriately. In the United States, 1 quart is equal to 4 cups. So, we will start by converting the coffee in the pot to cups.

The coffee pot originally contained 1 1/2 quarts of coffee. To find out how much this is in cups, we multiply by 4 (since there are 4 cups in 1 quart):

1 1/2 quarts = 1.5 quarts

1.5 quarts * 4 cups/quart = 6 cups

Thus, the coffee pot had 6 cups of coffee before Tony poured it into cups.

After pouring, 3 1/2 cups of coffee remain in the pot. To find out how much coffee was poured into the cups, we subtract the remaining coffee from the initial amount:

6 cups - 3 1/2 cups = 2 1/2 cups

This means that Tony poured a total of 2 1/2 cups of coffee into the cups. If we assume that he poured an equal amount into each cup, we would divide the total amount poured by the number of cups to find the amount per cup. However, since we don't know how many cups he filled, we can only conclude that Tony poured a total of 2 1/2 cups of coffee into an unspecified number of cups.

answer d, because the equation is stating 3= $4.41, we are trying to figure out how much 4 cost
so d is correct as if u wanted to find out how much one thing cost u need to divide the number of the thing by its cost .An example is 20dollars for 4 apples. so 20/4=5 dollars for each apple. 

This equation shows how much 3 erasers cost, which in this case its 4.41. the equation equals to 4/x as the cost of 1 eraser is the same. so if u wanted to solve this equation, u can use the cross method to multiply it so
