Is 81 in the sequence with the nth term 4n+1?
Explain

Answers

Answer 1
If you can divide 81 by 4 and end up with a remainder of 1, then yes, 81 is a part of your sequence.

To justify that, it helps to think about ways we can represent numbers in terms of quotients and remainders. For example, if we take 10/3, we’ll obtain the quotient 3 with a remainder of 1, so another way of writing 10 would be 3(3)+1. If we replace that second three with any integer n, 3n+1 represents *every number* that leaves us with a remainder of 1 when we divide it by 3.

By the same logic, 4n+1 represents every number that leaves a remainder of 1 when we divide it by 4. 81 indeed meets this requirement, since can be written as 4(20)+1, so it would be a part of the sequence.

Answer: The toy should be 2.4 inches tall

------------------------------------
------------------------------------

Explanation:

First convert 6 ft to inches
6 ft = (6 ft)*(12 in/1 ft) = (6*12) inches = 72 inches

So, 6 ft = 72 inches

The toy is manufactured with a scale of 1:30 meaning that the toy is 1 unit tall compared to the soldier which is 30 units tall. The soldier is 30 times taller than the toy. We can therefore form the ratio

1/30 = x/72

where x is the height of the toy soldier in inches

Cross multiply and solve for x

1/30 = x/72
1*72 = 30*x
72 = 30*x
72/30 = 30*x/30
72/30 = x
x = 72/30
x = 12/5
x = 2.4

So the toy should be 2.4 inches tall.

Note how 30 times 2.4 gives us
30*2.4 = 72
which fits with the theme that the real soldier is 30 times taller than the toy counter part.


30. The perimeter of a rectangle is 292 feet. The length of the rectangle is 4 feet less than 5 times the width. What is the length and width of the rectangle?
a. length = 121, width = 25​​b. length = 114.3, width = 23.7
c. length = 25, width = 121​​d. length = 121.7, width = 24.3

Answers

formula for perimeter ;
P = length + length + width + width 
P = 2l + 2w

l = -4 + 5w
l = 5w - 4

substitute into equation of perimeter 

292 = 2(5w - 4) + 2w

292 = 10w - 8 + 2w

292 + 8 = 10w + 2w 

300 = 12w

25 = w

substitute into eqution to find the length;

l = 5(25) - 4
l = 125 - 4
l = 121

therefore, the width is 25 and the length is 121

hope that helps, God bless!

Final answer:

To find the dimensions of the rectangle, the problem was solved by setting up and solving equations based on the given perimeter and the relationship between the length and the width. It was found that the width is 25 feet and the length is 121 feet.

Explanation:

To solve the problem, we first need to set up equations based on the information given. We are told the perimeter of a rectangle is 292 feet and that the length (L) is 4 feet less than 5 times the width (W). The formulas for the perimeter (P) of a rectangle is P = 2L + 2W. The relationship between the length and the width can be expressed as L = 5W - 4.

Substituting the second equation into the first, we get: 292 = 2(5W - 4) + 2W.

Simplifying, we find that 292 = 10W - 8 + 2W, leading to 300 = 12W. Therefore, W = 25 feet. Substituting back to find L, we find that L = 5(25) - 4 = 121 feet.

Thus, the width of the rectangle is 25 feet, and the length is 121 feet, which corresponds to option C).

splashtown charges an entrance fee of $25 plus $1 for each ride. Schlitterbahn charges a $40 entrance fee and all the rose are free. After how many rides would Schlitterbahn be cheaper than splashtown

Answers

Splashtown: 25 + 1x
Schlitterbahn: 40
25 + 1x = 40
-25 -25
0 1x = 15
x = 15
So after 15 rides, Schlitterbahn would be cheaper than Splashtown.

Schlitterbahn becomes cheaper than Splashtown after more than 15 rides.

Let's define x as the number of rides:

Cost of Splashtown: $25 + $1 * x
Cost of Schlitterbahn: $40

We need to find the value of x for which the cost of Splashtown becomes greater than the cost of Schlitterbahn.

$25 + $1x > $40

$1x > $40 - $25

x > $15

So, after more than 15 rides, Schlitterbahn would be cheaper than Splashtown.

Lina bought 4 smoothies at a health food store. The bill was less than $16.

Write and solve an inequality to represent the cost of each smoothie.

What values make sense for this situation?

Answers

The inequality representing the cost of each smoothie is 4x < 16, which simplifies to x < 4, denoting that the cost of each smoothie is less than $4. Sensible values are any positive numbers less than $4.

To represent the cost of each smoothie with an inequality, let's designate the cost of one smoothie as x. Since Lina bought 4 smoothies and the total cost was less than $16, the inequality to represent this situation is:

4x < 16

To solve this inequality, we'll divide both sides by 4:

x < 16 / 4

x < 4

The cost of each smoothie is less than $4.

Values that make sense for this situation would be any positive price per smoothie that is less than $4, as Lina's total purchase for 4 smoothies must not exceed $16. So, x could be any positive real number less than 4.

Estimate the value of 97.5 divided by 1.96

Answers

The estimated value is 50, which is close to the actual value of approximately 49.74.

To estimate the value of 97.5 divided by 1.96, we can round the numbers to make the calculation simpler.

Rounding 97.5 to 100 and 1.96 to 2 gives us an easier division: 100 divided by 2, which equals 50.

This estimation tells us that the actual value will be close to 50.

If we require more accuracy and use a calculator, we would find that 97.5 divided by 1.96.

= 9.75 / 1.96

= 49.74.

Therefore, our rounded estimate of 50 is reasonably close to the actual value.

A fair charges $7.25 for admission and $5.50 for a ride pass. Ten friends visited the fair. Not all of the friends purchased ride passes. If their total cost was $105.50, how many friends purchased ride passes?
tell me pls thank you

Answers

You take
7.25 (10)+5.5p=105.5
72.5+5.5p=105.5
To make the equation easier multiply the whole equation by ten like this
(72.5+5.5p=105.5)10 that equals
725+55p=1055
Then subtract 725 to both sides
725+55p=1055
-725 -725
____ _____
55p=330
Then divide by 55 on both sides and that equals 6 so 6 people bought tickets
Answer:

The number of friends who purchased ride passes= 6

Step-by-step explanation:

It is given that:

A fair charges $7.25 for admission and $5.50 for a ride pass.

Now, if 10 friends visited the fair.

This means that:

Total cost of admission= 7.25×10= $ 72.5

Also, if x friends purchased the ride passes.

Then, the total cost of ride passes= 5.50x

Total cost= 72.5+5.50x

This means that:

72.5+5.50x=105.50

i.e.

5.50x=105.50-72.5

5.50x=33

x=33/5.50

x=6

     Hence, 6 friends purchased ride passes.

The lizards in the show eat 250 crickets per week.About how any crickets do the lizards eat each day?Explain.

Answers

Each day the lizards eat about 36 crickets when we round to the nearest whole number

To calculate how many crickets the lizards eat each day, we need to divide the weekly intake by the number of days in a week. The lizards eat 250 crickets per week. There are 7 days in a week.

So, we divide 250 by 7 which equals approximately 35.71 crickets per day.

Therefore, each day the lizards eat about 36 crickets when we round to the nearest whole number, since you can't have a fraction of a cricket.

Hi there! To solve this problem, first, we need to combine like terms. When you do, you should get 7x - 8 = 8 + 3x. Now, subtract 3x from both sides to get the whole number on the right by itself. When you do, you get 4x - 8 = 8. Now, add 8 to both sides to get 4x on its side alone and you get 4x = 16. Now, divide each side by 4 to isolate the “x”. 16/4 is 4. There. x = 4.

A deep-sea diver must descend and ascend in short steps to equalize pressure on his body. If the diver rises toward the surface too fast, he may suffer from a physical condition called “the bends.” Suppose the diver started at 82 feet below the surface and rose in five steps of 15 feet each. Use an integer to describe his new position in relation to the water surface. is it positive or negative?

Answers

I would say the answer is -7 in relation to the surface.

The deep-sea diver started at 82 feet below the surface and rose in five steps of 15 feet each, which resulted in a new position of -7 feet. This indicates that the diver is still 7 feet underwater, so the integer representing his position is negative.

The diver starts at 82 feet below the surface and rises in five steps of 15 feet each. To find the new position, we start with the initial position and subtract the distance risen in each step:

Initial position: -82 feet (below water is considered negative)

Total rise: 5 steps × 15 feet/step = 75 feet

New position: -82 feet + 75 feet = -7 feet

Therefore, the diver's new position is -7 feet relative to the surface, indicating he is still 7 feet underwater, thus the integer is negative.
