Lola takes the train from Paris to Nice. The distance between the two cities is about 921,000 meters. If the train travels at a speed of 307 kilometers per hour, how long will it take Lola to travel from Paris to Nice

Answers

Distance =rate/time so your answer is 3 hours first you have to convert meters to kilometers 921000 meters = 921 Km so you have like terms to calculate so your distance becomes 921 Km then divide by the speed 907÷3 = 3 so your answer is 3 hrs

Answer: It will take 1.75 minutes to travel from Paris to Nice.

Step-by-step explanation:

Since we have given that

Distance between the two cities = 921,000 meters

Since we know that

1 km = 1000 meters

[tex]1\ m=\dfrac{1}{1000}\ km\\\\921000\ m=\dfrac{921000}{1000}\ km=921\ km[/tex]

Speed at which the train travels = 307 km/hr

As we know the formula for time taken:

[tex]Time=\dfrac{Distance}{Speed}=\dfrac{921}{307}=0.029\ hours\\\\Time=0.029\times 60=1.75\ minutes[/tex]

Hence, it will take 1.75 minutes to travel from Paris to Nice.

Noah wants to put $1,000 in a savings account with a 1.5% annual interest rate. How much more money will he have after one year if it is compounded monthly versus no compounding

A:$0.10
B:$15.00
C:$1015.00
D:$1015.10

Answers

Assuming that 1.5% annual interest is converted to monthly basis with the same amount, then the monthly interest should be: 1.5%/12= 0.125%.

If you put $1000 for annual interest, the saving account would become: $1000*(100%+1.5%)= $1015

If you put $1000 for monthly interest, the saving account would become: ($1000*(100%+0.125%)= $1000*1.0151035559= $1015.10

Then, the money difference should be:  $1015.10-$1015= $0.10

Find a number whose product with 9 is the same as its sum with 56

Answers

Let x be that number.
9x must be the same as x+56:
[tex] 9x = x+56[/tex].
We substruct x from both sides:
[tex] 8x = 56[/tex]
and we divide by 8 in both sides of the equality:
[tex] x = 7[/tex]

Final answer:

The requested number is 7, which when multiplied by 9 or added to 56, gives the same result of 63.

Explanation:

To find a number whose product with 9 is the same as its sum with 56, we set up the equation x * 9 = x + 56. Solving for x, we first distribute the 9 to the x, resulting in 9x = x + 56. Next, we subtract x from both sides to get 8x = 56. Finally, we divide both sides by 8 to find that x = 7. Hence, 7 is the number we are looking for, as 7 * 9 = 63 and 7 + 56 = 63, confirming that the product and the sum yield the same result.

In a certain grocery store, strawberries cost $4.48 per pound ( 4.48 dollars/lb ). What is the cost per ounce?

Answers

To solve this problem, all we have to do is to convert the pounds to ounce. We know that the conversion factor is:

1 pound = 16 ounce

Therefore:

cost per ounce = ($ 4.48 / pound) * (1 pound / 16 ounce) = $0.28 / ounce

Answer: There is cost $0.28 per ounce.

Step-by-step explanation:

Since we have given that

Cost per pound = $4.48

We need to find the cost per ounce.

As we know that

1 pound = 16 ounces

So, Cost per ounce would be

[tex]\dfrac{4.48}{16}\\\\=\$0.28[/tex]

Hence, there is cost $0.28 per ounce.

simplify the expression (2x − 9)(x + 6). 2x2 − 54

Answers

Answer:

2x²+3x-54

Step-by-step explanation:

To simplify the expression

(2x − 9)(x + 6)

We will multiply both linear equations together to get a quadratic equation of second degree.

(2x − 9)(x + 6)

= 2x²+12x-9x-54

= 2x²+3x-54

This gives the required quadratic expression after simplification.

Stan wants to make a rectangular garden. he has 34 ft of fencing to put around the perimeter. if the length is to be 5 ft more than the width, find the dimensions of the planned garden.

Answers

P = 2(L + W)
P = 34
L = W + 5

34 = 2(W + 5 + W)
34 = 2(2W + 5)
34 = 4W + 10
34 - 10 = 4W
24 = 4W
24/4 = W
6 = W <==== the width is 6 ft

L = W + 5
L = 6 + 5
L = 11 <==== the length is 11 ft
Final answer:

Using the concept of perimeter and given conditions, the planned garden's dimensions should be 6 feet by 11 feet with a total perimeter coverage of 34 feet.

Explanation:

The problem can be solved by using the concept of perimeter in mathematics. The perimeter of a rectangle is the sum of all its sides, and given that Stan has 34 ft of fencing, this can be translated to a formula: 2*(length + width) = 34ft.

From the question, we also know that the length of the fence is 5 ft more than the width. This can also be translated into an equation: length = width + 5.

By substituting this into the earlier equation, we can find the width: 2*(width + width + 5) = 34, which simplifies to 4*width + 10 = 34. Solving this gives us width = 6 ft.

Substitute width = 6 ft into the length equation to get length = width + 5 = 6 + 5 = 11 ft. Therefore, the dimensions of the planned garden are 6 ft by 11 ft.

please help !! A safety regulation states that the height h of a guardrail should be 106 centimeters with an absolute deviation of no more than 7 centimeters. Write and solve an absolute value inequality that represents the acceptable heights of a guardrail. The absolute value inequality is_ . The acceptable range of heights of a guardrail are _cm to _cm.

Answers

The height h of a guardrail = 106 centimeters

absolute deviation =  7 centimeters

To find the acceptable heights of a guardrail , we add and subtract absolute deviation(7) from the mean height(106)

The acceptable range of height is 7 cm away from 106 to the left and then to the right.

106 + 7 = 113

106 - 7 = 99

acceptable heights are defined by

99 <=h<=113

The absolute value inequality is |x-106|<=7

The acceptable range of heights of a guardrail are 99 cm to 113 cm.


We want to write an absolute value equation for the acceptable range of the height of a guardrail.

The acceptable range of heights of a guardrail is 99cm to 113cm.

And the absolute value equation is:  |h - 106cm| ≤ 7cm

We know that the height should be 106cm with an absolute deviation of no more than 7 cm.

So the maximum height is:

106cm +7cm = 113cm

The minimum is:

106cm -7cm = 99cm

The absolute value equation that represents this is:

|h - 106cm| ≤ 7cm

Where h is the height of the guardrail.

The acceptable range of heights of a guardrail is 99cm to 113cm.

Any number in the first set is automatically part of the second. We consider the first set to be a subset of the second set. Any natural number you can think of is also a whole number.

I'm not sure about part B, but part A will have the answer "if Ron eats lunch today, then he will drink a glass of milk" (without quotes of course)

The idea is that we have these arguments in symbolic form
P = Ron eats lunch today
Q = Ron eats a sandwich
R = Ron will drink a glass of milk

The format is 
"If P then Q" ----> "if Q then R"  so therefore "If P then R"

We see that P leads to Q, then Q leads to R. So overall P leads to R. We connect them as a chain of sorts. We can skip over Q since we know the first point will lead to the last. Think of it as a shortcut of sorts.

if f(x)=-6x+12, then f^-1(x)=

Answers

Hi!

Okay, so let's start with swapping all of the variables.

x = -6y + 12.

We'll start with subtracting both sides by 12. Our goal is to isolate y, and we do so by doing the inverse of the operation on each value.

Since 12 is positive, the inverse of being positive is negative. So, we shall subtract!

x - 12 = -6y + 12 - 12.

Which leaves us with x - 12 = -6y.

Since the -6 is multiplying our variable, the inverse of multiplication is division, so we shall divide both sides by -6.

[tex] \frac{x - 12}{-6} [/tex] = -6y / -6.

Which leaves us with [tex] \frac{x - 12}{-6} [/tex] = y.

Our final answer is:

[tex] f^{-1}(x) [/tex] = [tex] \frac{x - 12}{-6} [/tex].

Hopefully, this helps! =)
f(x) = -6x + 12

y = -6x + 12

Switching y and x, and then solving for y:

x = -6y + 12

6y = 12 - x

y = [tex] \frac{12- x}{6} [/tex]

Hence, 

[tex] f^{-1} (x) = \frac{12- x}{6}[/tex]
