We'd need to figure out the side of the bigger pentagon, which is going to be messy, but we can do it!

The area of a pentagon equation is messy, and we need to solve for the side given the area, which would be sqrt((4*area)/((5(5+2sqrt(5)))^(1/2)) or sqrt((4*8)/((5(5+2sqrt(5)))^(1/2)) . We get this from the pentagon equation, multiplying both sides by 4 dividing (5(5+2sqrt(5)))^(1/2)) from both sides, then square rooting that to get the side length

Plugging it in, we get 2 and some more, and we multiply that by 2 to get the bigger side length. Plugging that into the area equation, we get a=32 and 32-8=24

A 25-N net force is applied to a rolling cart and produces an acceleration of 5 m/s2.What is the cart's mass

Answers

Remember that Force= mass*acceleration.
Plug in the known values

25 = m* 5

Divide both sides by 5
5= m

Final answer: The mass is 5 kg

The mass of the cart is 5 kg

The calculation can be done as follows

Force= 25 N

Acceleration= 5 m/s²

The mass can be calculated as follows

Force= mass × acceleration

25= mass × 5

mass= 25/5

= 5 kg

Hence the mass of the cart is 5 kg

it rounded to the nearest dime what is the greatest amount of money that rounds to $105.40

Answers

The greatest amount of money that could be rounded to $105.40 would be $105.44. Any higher, and it would be rounded to $105.50.

Answer:

$105.44.

Step-by-step explanation:

We are asked to find the the greatest amount of money that rounds to $105.40, rounded to the nearest dime.

We know that when the next digit to rounded digit is 0, 1, 2, 3, 4; then we keep the same digit.

When the next digit to rounded digit is 5 or more than 5; then we round up our answer by one digit.

We know that 1 dime equals $0.10.

Since our answer in rounded to nearest dime, so the hundredths digit will be less than 5.

Therefore, the greatest amount of money would be $105.44.

Solve for x, Show your work: 1/2 (16 - x) = -12 (x + 7)

Answers

You have to get rid of 1/2 by multiplying it by its recriprocal which is like this:
1) 1/2 x 2/1 which equals to zero and you do the same to the other side.
2) -12 x 2/1 = -24x then multiply-24x with 7 which equals -168.
16-x= -24x -168
3) subtract 16 to the other side and subtract 24x with x
23x= -184
4) divide by 23 to isolate x and you get -8
5) x=-8

First you need to multiply 1/2 by 16, then multiply 1/2 by x to get 8-1/2x=-12(x+7). Then you multiply-12 by x to get-12x an then you multiply-12 by 7 so your equation looks like this 8-1/2x=-12x+-84. Combine the like terms and divide by the number with the x and you have your answer

the rivers family plans to travel to the beach for a summer vacation the family spend 67.50 for 23 gallons of gasoline the distance between their home and the beach is approximately 350 miles to the nearest cent how much money did the rivers family spend per gallon on gas for the trip

Answers

Final answer:

To find the cost per gallon of gasoline for the Rivers family, we divide the total amount spent on gas ($67.50) by the total number of gallons purchased (23). This gives us an approximate cost of $2.93 per gallon for their trip to the beach.

Explanation:

A common way to analyze such problems is to determine the cost per unit, in this case, the cost per gallon of gasoline. The Rivers family spent $67.50 on 23 gallons of gasoline. To figure out how much they spent for each gallon of gasoline, we divide the total cost by the quantity of gallons.

So, the calculation is $67.50 / 23 gallons, which is approximately $2.93 per gallon. Hence, for this trip to the beach, the Rivers family was spending around $2.93 for each gallon of gasoline they purchased.
