The body of a 154-pound person contains approximately 300 times more milligrams of aluminum than milligrams of gold. This is found by dividing the amount of aluminum (60 milligrams) by the amount of gold (0.2 milligrams).
Explanation:To find out how many times the number of milligrams of aluminum is compared to that of gold in a 154-pound human body, we need to divide the amount of aluminum by the amount of gold. The problem states that there are 2 X 10^-1 milligrams of gold and 6 X 10^1 milligrams of aluminum. If we simplify these expressions, we get 0.2 milligrams of gold and 60 milligrams of aluminum.
Next step is to divide the number of milligrams of aluminum by the number of milligrams of gold. Hence, 60 ÷ 0.2 gives us 300.
Therefore, the body of a 154-pound person contains approximately 300 times more aluminum than gold.

The base of a pryramid can be any polygon how many faces does a pentagonal pyramid have ? Describe the shapes of the faces 22 points plz help give a good answer
A pentagonal pyramid has six faces: one pentagonal base and five triangular lateral faces. Each side of the pentagonal base connects to the apex forming five triangular faces. The total number of faces is six.
A pyramid is a three-dimensional geometric shape with a polygon as its base and triangular faces that meet at a single point called the apex.
A pentagonal pyramid has a base in the shape of a pentagon.
The total number of faces in a pentagonal pyramid equals the number of sides on the base (5) plus one more for the base itself, giving a total of six faces.
Thus, a pentagonal pyramid consists of six faces - one pentagonal base and five triangular lateral faces.

A circle has an area of 78.5 square inches. What is the diameter of the circle?
To determine the diameter of a circle with an area of 78.5 square inches, we solve for the radius using the area formula (A = πr²). We find the radius to be 5 inches, and since the diameter is twice the radius, the diameter is 10 inches.
Explanation:The student has asked how to determine the diameter of a circle if the area is known to be 78.5 square inches. To find the diameter, we first need to calculate the radius using the area formula for a circle, which is A = πr², or area equals pi times the radius squared. Pi (π) is approximately 3.14159, but for most calculations, we can use 3.14 for simplicity.
To solve for the radius, we rearrange the formula to r² = A / π. Plugging in the given area of 78.5 square inches:
r² = 78.5 / 3.14 = 25
Next, we take the square root of both sides to find the radius: r = √25 = 5 inches.
Now that we have the radius, we can determine the diameter by multiplying the radius by 2, as the diameter is twice the length of the radius. Thus, the diameter of the circle is 10 inches.

what is the answer to 5+2x10
We are given expression : 5+2x10.
It can be read as 5 plus 2 times 10.
Now, we need to see, what operation should carry out first.
Please note: We always follow the order of operations.
The order of operations could be follow by the rule PEMDAS.
It stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.
We don't have Parentheses, Exponents in the given problem.
So, we would start order of operations: first multiplication and then addition.
So, we need to multiply 2 × 10 first.
2 × 10 = 20.
Now, we need to apply addition operation.
Therefore, 5+2x10 = 5+20.
On adding 5 and 20, we get 25.
So, the final answer is 25.
Answer:
25 (assuming the x means multiplication)
Step-by-step explanation:
Start by using PEMDAS (Parenthesis, exponents, multiplication and division from right to left, addition and subtraction from right to left) you would start with multiplication or 2x10 which is 20 and then you have 5+20 left and that is obviously just 25

all tickets for a concert are the same price.the ticket agency adds a fixed fee to every order.a person who orders 5 tickets pays $93.a person who buys 3 tickets pays $53
The question can be solved using a system of linear equations. The price of each ticket is found to be $20, and the fixed fee added by the ticket agency is $13.
Explanation:The subject of this question concerns solving a system of linear equations. Given the two scenarios, buying 5 tickets for $93 and buying 3 tickets for $53, we can represent these as equations where 't' represents the price of a ticket and 'f' represents the fixed fee. The equations thus become:
5t + f = 933t + f = 53
To solve this system of equations, we could subtract the second equation from the first, which would eliminate 'f' and yield an equation only in terms of 't'. This would look like:
2t = 40
From here, we can see that t (the price of each ticket) equals $20. We can then substitute 't' into one of the equations to find the fixed fee 'f', which in this case equals $13.

Answer:
60 tokens and the rule is the number of tokens divided by 2
20 cups of oats and the number of cups of raisins times 2
Rosa can play a total of 60 games with 120 tokens.
Explanation:To determine the number of games Rosa can play with 120 tokens, we need to divide the total number of tokens by the number of tokens required to play a game. Since each game costs 2 tokens, we divide 120 by 2. This gives us the number of games Rosa can play, which is 60.
We can also write a rule to calculate the number of games Rosa can play. Let G represent the number of games, and T represent the number of tokens. The rule would be: G = T ÷ 2. We can substitute T with 120 to find G: G = 120 ÷ 2 = 60.

The temperature in degrees Fahrenheit when it is 90 °C is approximately 194 °F. Therefore, option d is the correct answer.
Let's use the correct formula [tex]F = \frac{9}{5}C +32[/tex] to find the temperature in degrees Fahrenheit when it is 90 °C.
[tex]F = \frac{9}{5} *90+32[/tex]
Now, let's calculate:
[tex]F = \frac{9}{5} *90+32[/tex]
F=162+32
F=194
Therefore, the temperature in degrees Fahrenheit when it is 90 °C is approximately 194 °F.
So, the correct answer is D. 194 °F.

Which expression is NOT equivalent to 8 times −5 and 1/4?
Drag this expression to the box.
Answer:
Step-by-step explanation:
Two cyclists leave town at the same time on the same road going in the same direction. Cyclist a is going 6 miles per hour faster than cyclist b. After 8 hours, cyclist a has traveled three times the distance as cyclist b. Use the equation 24x= 8(x+6) to find how fast cyclist b was traveling.
Answer:
3 mph
Step-by-step explanation:
Two cyclists leave town at the same time on the same road going in the same direction.
Cyclist A is going 6 mph faster than cyclist B
Let speed of cyclist B be x mph
Speed of cyclist A be (x+6) mph
Both cyclist leave town at the same time and traveled 8 hours.
Distance covered by cyclist A in 8 hours= 8(x+6)Distance covered by cyclist B in 8 hours= 8xAfter 8 hours cyclist A has traveled 3 times the distance as cyclist B
Therefore, 8(x+6) = 3(8x)
8x + 48 = 24x
24x - 8x = 48
16x = 48
x = 3 mph
Hence, The speed of cyclist B was 3 mph
Daniel gets a weekly $10 allowance. He has swimming class once a week and pays a $1.50 pool fee. After class, he sometimes goes out to eat with friends and spends $5 to $10. He is saving up for new swim trunks and sets aside $2.50 per week. Every few weeks, he goes to a swim meet in another town and spends $3 to $9 on bus fare.
This month, Daniel went out with friends and spent $8.50 for lunch. He went to 2 swim meets and spent $7 on bus fare each time. What are this month’s totals of his fixed and variable expenses?
fixed expenses total: $ ___
variable expenses total: $ ___
We have been given that Daniel's weekly allowance is $10 and we have to figure out his monthly fixed and variable expenses. To tackle this problem we have to figure out what are fixed expenses and what are variable expenses.
Fixed expenses are not going to vary as they are fixed. We have been given that Daniel has swimming class once a week and pays a $1.50 pool fee. Daniel is also saving for a new swimming trunks and sets aside $2.50 per week.
Variables expenses vary in a given range. We have been given that Daniel sometimes goes out to eat with friends and spends $5 to $10. Daniel goes to a swim meet in another town and spends $3 to $9 on bus fare.
Now let us find monthly fixed expenses first. [tex]1.50+2.50[/tex] are his weekly fixed expenses. To figure out monthly expenses we will multiply weekly expenses by 4 because a month has four weeks.
Monthly fixed expenses=[tex]4\times (1.50+2.50)=4\times 4=16[/tex]$
Now we will figure out monthly variable expenses. We have been given that Daniel has spent $8.50 for lunch and gone for two swim meets costing $7 each.
Monthly variable expenses=[tex]8.50+2\times 7=8.50+14=22.50[/tex]$
