the 7 in the thousands place is 10 times greater than the 7 in the hundreds place?

the 7 in the thousands place is 100 times greater than the 7 in the hundreds place?

the 7 in the thousands place is 7 times greater than the 7 in the hundreds place?

Answers

Answer 1
The first one is correct. The 7 in the thousands place is 10 times greater than the 7 in the hundreds place.
Answer 2
Final answer:

The 7 in the thousands place is ten times greater than the 7 in the hundreds place, adhering to the base-10 structure of our numbering system; other proposed multipliers are incorrect.

Explanation:

The question explores the concept of place value in our decimal numbering system, which is based on powers of ten. Specifically, it examines the comparative value of digits in the thousands and hundreds places. Using the decimal system, each place value to the left is ten times greater than the one immediately to its right.

The second statement suggesting that the 7 in the thousands place is 100 times greater is incorrect; it overlooks the base-10 structure of our numbering system. Finally, the suggestion that the 7 in the thousands place is 7 times greater is also incorrect, as it misinterprets the multiplicative property of the decimal system. Therefore, the 7 in the thousands place being 10 times, 100 times, or 7 times greater than the 7 in the hundreds place aligns with the concept of powers of 10.

Answers

Okay. So to solve this problem, we have to try out each of the values to see what we get. x is the number up front and y is the number that is second in line. 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.
the answers are (-1,-7) and (-6,-14) HOPE IT HELPS.

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.

Hi there!

It appears you've written the equation wrong.

It should be: 13 + 1.5n ≤ 35.5

(13 - 13) + 1.5n ≤ (35.5 - 13)

1.5n ≤ 22.5

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.

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.

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

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.

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.
